polymer materials, in particular relates to a single yarn, a single
yarn product and a preparation method thereof.
BACKGROUND OF THE INVENTION
[0002] Ultra high molecular weight polyethylene (Ultra High

high; and furthermore, in the preparation process of the product,
the surfaces of the fibers are liable to the generation of burrs
due to friction, and the fibers are liable to breaking, distortion,
intertwining and other phenomena, thereby being not conductive to
realizing integral uniform stress of the multiple fibers, enabling
the strength of the integral strength of the prepared product to be
often lower than the strength of the multiple ultra high molecular
weight polyethylene fibers and realizing a relatively low strength
utilization ratio.

to the implementation ways must be made to facilitate the
implementation of specific targets of development staff, such as
those limiting conditions which are related to a system and
business, and these limiting conditions can change along with
different implementation ways. In addition, it should also be
understood that, although the development work may be very complex
and time-consuming, the development work is just a routine task for
those skilled in the art and benefiting from the disclosure of the
present invention. Herein, it still needs to be noted that, in
order to prevent the unnecessary details from obscuring the present
invention, only the device structure and/or the treatment steps
which are closely related to the solutions of the present invention
are described in the accompanying drawings and the description, and
the representations and the descriptions of the parts and the
treatments which are not closely related to the invention and known
to those of ordinary skill in the art are omitted.
[0035] Ultra high molecular weight polyethylene is polyethylene
with a molecular weight of above 1 million. The traditional
technologies using the ultra high molecular weight polyethylene
take ultra high molecular weight polyethylene fibers as the basis
to prepare various products. The technical solutions provided by
the various embodiments of the present invention are essentially
different from the traditional technologies using ultra high
molecular weight polyethylene and are revolutionary innovations
against the traditional technologies, namely, an ultra high
molecular weight polyethylene thin film or strip is used for
replacing traditional ultra high molecular weight polyethylene
fibers to develop and prepare application products, and the core
concept mainly includes the following contents:
(1) The ultra high molecular weight polyethylene thin film or strip
is used for replacing traditional ultra high molecular weight
polyethylene fibers to prepare a single yarn, namely, the single
yarn is prepared by converging or converging and twisting the ultra
high molecular weight polyethylene thin film or strip. (2) The
single yarns obtained by converging or converging and twisting the
ultra high molecular weight polyethylene thin films or strips
replace the traditional ultra high molecular weight fibers in the
development of various products (hereinafter referred to as single
yarn products).
[0036] Wherein, as shown in FIG. 1a, the ultra high molecular
weight polyethylene thin film 101 is a thin slice which is prepared
from ultra high molecular weight polyethylene and has a certain
width and thickness, wherein the width is much greater than the
thickness. As shown in FIG. 1b, the ultra high molecular weight
polyethylene strip 102 is a strip-like thin slice which can be
prepared independently or be formed by performing slitting process
step before and after stretching the thin film, wherein the width
of the strip is less than the width of the thin film, and the
thickness is equivalent to that of the thin film or greater than
the thickness of the thin film.
[0037] The ultra high molecular weight polyethylene thin film or
strip provided by the present invention is different from the ultra
high molecular weight polyethylene fibers and also different from a
plane formed by bonding the multiple ultra high molecular weight
polyethylene fibers, and the significant difference lies in that
the ultra high molecular weight polyethylene thin film or strip
provided by the present invention has a certain width and thickness
and is an integral structure without integration points or trim
lines.
[0038] The single yarn provided by each of the various embodiments
of the invention is prepared on the basis of the ultra high
molecular weight polyethylene thin film or strip. In the
preparation process of the single yarn, the ultra high molecular
weight polyethylene thin film or strip is taken as a whole for
treatment, thereby having good structural integrity, being simple
in preparation process, eliminating a complex process for
respectively arranging multiple fiber silks, obviously reducing the
probability of generating burrs on the surface of the thin film or
strip and also obviously reducing the probability of producing
breaking, distortion, intertwining and other phenomena in the thin
film or strip. When the single yarn formed by converging the ultra
high molecular weight polyethylene thin film or strip is used for
bearing a load, the ultra high molecular weight polyethylene thin
film or strip is stressed as a whole, so that the strength of the
single yarn adopting the ultra high molecular weight polyethylene
thin film or strip is higher than that of a product prepared by
adopting the ultra high molecular weight polyethylene fiber with
the same denier number, and the single yarn has the advantages of
good structural integrity, high strength, high strength utilization
ratio, high production efficiency, low processing cost, light
weight, small linear density, good flexibility and the like.
[0039] The single yarn provided by each of the various embodiments
of the present invention can completely replace traditional ultra
high molecular weight polyethylene fibers to prepare the products
to be widely applied in various fields. Specifically, in various
embodiments of the present invention, the single yarn can
substitute the ultra high molecular weight polyethylene fibers to
prepare various single yarn products. In the preparation process of
the single yarn product, the single yarn is taken as the basis for
processing treatment. Compared with the similar products obtained
by processing treatment on the basis of the ultra high molecular
weight polyethylene fibers, the single yarn product has the
advantages of good structural integrity, simple preparation process
and high production efficiency. When the single yarn product bears
the load, each single yarn is stressed as a whole, so that the
strength of the single yarn product prepared by adopting the single
yarns is higher than that of the similar product prepared on the
basis of the ultra high molecular weight polyethylene fibers with
the same denier number, the strength utilization ratio is
effectively improved, and the single yarn product simultaneously
has the advantages of good structural integrity, light weight,
small linear density, environmental friendliness and the like.
[0040] Embodiment of Single Yarn and Preparation Method Thereof
[0041] A single yarn 201 provided by an embodiment of the present
invention is formed by converging an ultra high molecular weight
polyethylene thin film or strip. As shown in FIG. 2, the ultra high
molecular weight polyethylene thin film or strip can be converged
to prepare the single yarn. For example, an optional process flow
is as follows: placing the ultra high molecular weight polyethylene
thin film or strip on a bobbin creel, releasing and enabling the
ultra high molecular weight polyethylene thin film or strip to
sequentially pass through a thread guide mechanism and a bunching
mechanism and then be wound on a tube core. The prepared single
yarn has the advantages of good structural integrity, high
strength, high strength utilization ratio, high production
efficiency, low processing cost, light weight, good flexibility and
the like. In addition, as the single yarn is formed by converging
the ultra high molecular weight polyethylene thin film or strip,
compared with the similar products formed by bonding the ultra high
molecular weight polyethylene fibers, the single yarn further has
the advantages of no glue, environmental friendliness and the
like.
[0042] Optionally, the single yarn can also be prepared by
converging and twisting the ultra high molecular weight
polyethylene thin film or strip, namely, the ultra high molecular
weight polyethylene thin film or strip is firstly converged and
then twisted to prepare the single yarn. The twisting direction and
the twist for twisting can be determined according to actual needs
and are not limited in the various embodiments of the present
invention, for example, the twisting direction for twisting of the
ultra high molecular weight polyethylene thin film or strip can be
left twisting or right twisting, and the twist is 1-100/m. The
single yarn prepared according to the solution further has the
advantages of good compactness and effect of being less liable to
looseness, is convenient to process the single yarn product and can
reduce the processing cost and improve the production
efficiency.
[0043] Optionally, in the preparation process of the single yarn,
the ultra high molecular weight polyethylene thin film or strip can
be converged along the straightening direction of a molecular chain
thereof. As the ultra high molecular weight polyethylene has a
linear structure, the strength of the ultra high molecular weight
polyethylene thin film or strip along the straightening direction
of the molecular chain thereof is the maximum. Thus, when the
single yarn is prepared by converging along the straightening
direction of the molecular chain thereof, the strength of the
single yarn can be improved, the loss which may be caused to the
strength performance of the thin film for strip by converging
treatment can also be reduced, and the strength utilization rate is
high.
[0044] Optionally, the related parameters of the ultra high
molecular weight polyethylene thin film at least meet one and more
of the following conditions: the linear density is above 5000
deniers; the width is above 100 mm; the thickness is below 0.2 mm;
the breaking strength is above 10 grams/denier; the tensile modulus
is above 800 grams/denier; and the elongation at break is below
6%.
[0045] By preparing the single yarn on the basis of the ultra high
molecular weight polyethylene thin film with one or more
above-mentioned properties, the single yarn has higher integral
strength and can better meet the preparation requirements of
high-strength load, bulletproof and other products.
[0046] Optionally, the related parameters of the ultra high
molecular weight polyethylene thin film at least meet one or more
of the following conditions: the linear density is above 100
deniers; the width is 1-100 mm; the thickness is below 0.2 mm; the
breaking strength is above 10 grams/denier; the tensile modulus is
above 800 grams/denier; and the elongation at break is below 6%. By
preparing the single yarn on the basis of the ultra high molecular
weight polyethylene strip with one or more above-mentioned
properties, the single yarn has higher integral strength and can
better meet the preparation requirements of high-strength load,
bulletproof and other products.
[0047] In addition to the advantages of wear resistance, impact
resistance, corrosion resistance, UV resistance and the like which
are similar to those of the ultra high molecular weight
polyethylene fibers, the single yarn formed by converging or
converging and twisting the ultra high molecular weight
polyethylene thin film or strip provided by the various solutions
in this embodiment also has the unique advantages of good
structural integrity, high strength, high strength utilization
ratio, high production efficiency, low processing cost, light
weight, small linear density and the like, and therefore the single
yarn can replace traditional ultra high molecular weight
polyethylene fibers in the preparation of the various products and
is widely used in various fields, such as civil use, individual
protection, national defense military supplies, civil engineering,
industrial construction, offshore operations, fishing, ship
manufacturing, sports goods and the like.
[0048] Embodiment of Single Yarn Product and Preparation Method
Thereof
[0049] The single yarn product provided by the embodiment includes
at least a body prepared from the above-mentioned single yarn.
Namely, the single yarn product can be the body prepared from the
single yarns, or the single yarn product includes not only the body
prepared from the single yarns, but also a reinforcer, a
flame-retardant layer and other accessories, and the composition is
not limited in the invention. After the body is prepared from the
single yarns, if the preparation of the single yarn product
includes not only the body, but also the reinforcer, a
flame-retardant sleeve and other accessories, the processing of
other accessories can be implemented by adopting the prior art,
which will not be described in detail herein.
[0050] The single yarn product provided by the embodiment of the
present invention uses the single yarns formed by converging or
converging and twisting the ultra high molecular weight
polyethylene thin films or strips to replace traditional ultra high
molecular weight polyethylene fibers as raw materials and is
prepared by adopting one or more processes of unidirectional
arranging, converging, twisting, interweaving, bonding,
intertwining, hot-pressing and the like.
(1) Optionally, the multiple single yarns are unidirectionally
arranged, connected, converged, twisted, interwoven, bonded,
intertwined and/or hot-pressed into a whole to prepare the body of
the single yarn product.
[0051] For example, the multiple single yarns formed by converging
the ultra high molecular weight polyethylene thin films or strips
can be twisted to prepare a twisted rope. The product form of the
twisted rope prepared by the solution is not limited, for example,
the twisted rope can be used as a brake rope, a guide rope of a
helicopter, a suspension rope on a deceleration parachute or an
aircraft, an electric traction rope and the like, and the twisted
rope can better meet the special requirements of these products on
strength, weight and other performances of the ropes.
[0052] For example, the single yarns prepared by converging and
twisting the ultra high molecular weight polyethylene thin films or
strips can be processed into a woven fabric or strip 301 (as shown
in FIG. 3), a knitted fabric or strip 401 (as shown in FIG. 4), a
plaited fabric or strip, a net 501 with a mesh structure (as shown
in FIG. 5) and other single yarn products by adopting weaving,
knitting, plaiting and other interweaving processes. The product of
the single yarn product prepared by the solution can include, but
is not limited to, an airfreight net, a deep water net cage, an
ocean-going drag net, a high-strength structure, a high-strength
suitcase, a high pressure-resistant storage tank, a bulletproof
vest, a bulletproof plate, a geogrid, a bulletproof and
explosion-proof suitcase, an armored plate, a protection door, a
bulletproof seat and the like, and the single yarn product can
better meet the special requirements of these products on strength,
weight and other performances of the products.
[0053] For example, the single yarns formed by converging and
twisting the ultra high molecular weight polyethylene thin films or
strips can be unidirectionally interwoven and sewn side by side to
form the shape of a flat strip. The product of the single yarn
product prepared by the solution can include, but is not limited
to, a hoisting strip and the like, and the single yarn product can
better meet the special requirements of these products on strength,
weight and other performances of the products.
(2) Optionally, the multiple single yarns can be converged,
twisted, interwoven, bonded, intertwined and/or hot-pressed into a
whole to form a single-strand structure, and the multiple
single-strand structures were plied into a whole. The plying
implementation ways can include, but are not limited to twisting,
interweaving, bonding, intertwining, sewing and/or hot-pressing to
form a whole.
[0054] For example, the multiple single yarns are converged and
then twisted to prepare a single-strand structure, and the multiple
single-strand structures were twisted into a whole to prepare a
twisted rope 601 (as shown in FIG. 6). The number of strands of the
twisted rope can be determined according to actual needs and is not
limited in the present invention. The twisted rope with a
multi-strand structure has better strength than the single-strand
twisted rope, and can be, but is not limited to, a brake rope, a
guide rope of a helicopter, a suspension rope on a deceleration
parachute or an aircraft, an electric traction rope and the like,
and the twisted rope can better meet the special requirements of
these products on strength, weight and other performances of the
ropes.
[0055] For example, the multiple single yarns can be interwoven
into a whole by adopting a weaving process to prepare a woven rope
701 (as shown in FIG. 7). The product form of the single yarn
product prepared by the solution can include, but is not limited
to, a guide rope of a helicopter, a suspension rope on a
deceleration parachute or an aircraft, an electric traction rope; a
ship mooring rope, a cable rope, an anchoring rope, a tank drag
rope and fixed anchoring ropes for supertankers, ocean engineering
and lighthouses.
[0056] Example 3: the multiple single yarns can be unidirectionally
arranged and connected into a whole to prepare a single yarn
product with a single-layer structure.
[0057] For example, the multiple single yarns can be arranged in
parallel along the length direction of the single yarns and
connected into a whole through binding connection, bonding or
hot-pressing connection and other non-interweaving ways to prepare
a unidirectional fabric 801 (as shown in FIG. 8). The
unidirectional fabric prepared by the solution can be used for, but
is not limited to, the preparation of strengthening structures,
high-strength suitcases, bulletproof plates, impact-resistant
plates, bulletproof helmets, bulletproof and explosion-proof
suitcases and other products, and can better meet the special
requirements of these products on strength, weight,
bullet-proofness and other performances of fabric.
[0058] Example 4: single-layer structures obtained by
unidirectionally arranging and connecting the multiple single yarns
are crisscross compounded and laminated into a whole at certain
angles to prepare a single yarn product with a multi-layer
structure. Wherein, the intersection angles of any two adjacent
single-layer structures can be the same, the intersection angles
can be any angle in the range of 0-90 degrees, for example, the
intersection angle is 45 degrees; or the intersection angle is 90
degrees, if the multiple layers of the unidirectional fabrics 801
are sequentially crisscross laminated by 0/90 degrees, and the
various layers of the unidirectional fabrics are bonded or
hot-pressed for connection, thereby preparing the single-yarn
product with the multi-layer structure, such as a non-woven fabric
901 (as shown in FIG. 9). The single yarn production prepared by
the solution has high strength, when the single yarn product is
subject to shooting of a bullet and other strong impact force, a
force-bearing point can be diffused to a force-bearing surface,
energy is rapidly diffused, and the bulletproof performance is
good. Based on the single yarn product, the single yarn products
with other product forms can be further prepared, such as non-woven
fabric, strengthening structures, high-strength suitcases,
bulletproof plates, impact-resistant plates, bulletproof helmets,
bulletproof and explosion-proof suitcases and other products, and
the single yarn products can better meet the special requirements
of these products on strength, weight, bullet-proofness and other
performances.
[0059] Or, the intersection angles of at least two single-layer
structures in the various single-layer structures are different
from the intersection angles of other single-layer structures. For
example, if the intersection angles of the two adjacent
single-layer structures from the first single-layer structure are
gradually increased, the single-layer structures with different
intersection angles (unidirectional fabric 801) are laminated into
a whole, thereby preparing the single yarn product with the
multi-layer structure 1001 (as shown in FIG. 10). The single yarn
products with other product forms can be further prepared on the
basis of the single yarn product, such as strengthening structures,
high-strength suitcases, bulletproof plates, impact-resistant
plates, bulletproof helmets, bulletproof and explosion-proof
suitcases and other products, and the single yarn products can
better meet the special requirements of these products on strength,
weight, bullet-proofness and other performances.
[0060] According to the various solutions in the embodiment, the
single yarns obtained by converging or converging and twisting the
ultra high molecular weight polyethylene thin films or strips
replace traditional ultra high molecular weight fibers as the raw
materials to prepare various single yarn products. In the
preparation process of the single yarn product, the single yarn is
taken as the basis for processing treatment. Compared with the
similar products obtained by processing treatment on the basis of
the ultra high molecular weight polyethylene fibers, the single
yarn product has the advantages of good structural integrity,
simple preparation process and high production efficiency. When the
single yarn product bears the load, each single yarn is stressed as
a whole, so that the strength of the single yarn product prepared
by adopting the single yarns is higher than that of the similar
product prepared on the basis of the ultra high molecular weight
polyethylene fibers with the same denier number, the strength
utilization ratio is effectively improved, and the prepared single
yarn product further has the unique advantages of good structural
integrity, high strength, high strength utilization ratio, high
production efficiency, low processing cost, light weight, small
linear density and the like, and can be widely used in various
fields, such as civil use, individual protection, national defense
military supplies, civil engineering, industrial construction,
offshore operations, fishing, ship manufacturing, sports goods and
the like.
