Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention generally relates to a yarn manufacturing
method and a mixed yarn thereof.
[0003] 2. Description of the Prior Art
[0004] Fleck fancy mixed yarns have long been favored by consumers
due to the special appearance design and thus have relatively high
marketability. However, a conventional fleck fancy mixed yarn is
manufactured by spinning un-dyed fibers with pre-dyed fibers. In
other words, dyed fibers of different color must be prepared for
fleck fancy mixed yarns having different fleck color. The cost of
the conventional manufacturing method of fleck fancy mixed yarn is
relatively high, and the efficiency is hard to be increased.
Therefore, a novel method to make a fleck fancy mixed yarn is
needed.
SUMMARY OF THE INVENTION
[0005] It is an object of the present invention to provide a yarn
manufacturing method to make a fleck fancy mixed yarn.
[0006] It is another object of the present invention to provide a
yarn manufacturing method to make a fleck fancy mixed yarn more
efficiently.
[0007] It is another object of the present invention to provide a
mixed yarn having a fleck fancy effect.
[0008] The yarn manufacturing method includes providing a plurality
of raw fibers, modifying at least one of the raw fibers to form at
least one modified fiber, and spinning the raw fibers and the at
least one modified fiber into a mixed yarn. The yarn manufacturing
method further includes dyeing the mixed yarn.
[0009] The step of modifying the raw fiber includes attaching a
modifier to the raw fiber. The modifier may include a cation
modifier for enabling the modified fiber to be dyeable with an
acidic dye. The modifier may include a color enhancer for
increasing the affinity of the modified fiber to a dye. The
modifier may include a hydrophobic agent for decreasing a
hydrophile of the modified fiber. The modifier may include a
hydrophobic oil-proof agent for enabling the modified fiber to be
hydrophobic and oil proof. The modifier may include a sunlight
resistant agent for enabling the modified fiber to be sunlight
resistible.
[0010] In one embodiment, the raw fibers may include natural fibers
which are selected from a group consisting of cotton fibers, wool
fibers, linen fibers, jute fibers, ramie fibers, shengma fibers,
and hemp fibers. In another embodiment, the raw fibers may be
selected from a group consisting of polyethylene terephthalate
polymers, polyamide 6 polymers, polyamide 66 polymers, Nylon 6
polymers, Nylon 66 polymers, polypropylene polymers, and
polyolefin.
[0011] The mixed yarn of the present invention is spun from at
least one raw fiber and at least one modified fiber, wherein the at
least one modified fiber is modified from the at least one raw
fiber.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] FIG. 1 is a flow chart of the embodiment of the present
invention; and
[0013] FIG. 2 is a flow chart of another embodiment of the present
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] A flow chart of a first embodiment of the present invention
is shown in FIG. 1, wherein the yarn manufacturing method includes
the following steps.
[0015] Step 1010, a step of providing a plurality of raw fibers is
performed. In one embodiment, the raw fibers include natural fibers
which are selected from a group consisting of cotton fibers, wool
fibers, linen fibers, jute fibers, ramie fibers, shengma fibers,
and hemp fibers. In another embodiment, the raw fibers can be
selected from a group consisting of polyethylene terephthalate
polymers, polyamide 6 polymers, polyamide 66 polymers, Nylon 6
polymers, Nylon 66 polymers, polypropylene polymers, and
polyolefin.
[0016] Step 1030, a step of modifying at least one of the raw
fibers to form at least one modified fiber is performed. The step
of modifying the raw fiber includes attaching a modifier to the at
least one raw fiber. More particularly, the modifier is attached to
the surface of the at least one raw fiber by adsorption or
absorption and is adhered to the surface of the at least one raw
fiber after the at least one raw fiber is dried.
[0017] The modifier is configured to enable the fiber to have a
predefined ability. In other words, different modifiers can provide
the fiber with different abilities. For example, the modifier may
include a cation modifier for enabling the at least one modified
fiber to be dyeable with an acidic dye. The cation modifier is
preferably but not limited to a material selected from a group
consisting of a quaternary ammonium, a tertiary ammonium, an
aluminum polymer, and a combination thereof. Furthermore, the
modifier may include a color enhancer for increasing the affinity
of the at least one modified fiber to a dye. The color enhancer is
preferably but not limited to a material selected from a group
consisting of a quaternary ammonium, a tertiary ammonium, an
aluminum polymer, and a combination thereof. Moreover, the modifier
may include a hydrophobic agent for decreasing a hydrophile of the
at least one modified fiber. The hydrophobic agent is preferably
but not limited to a material selected from a group consisting of
fluorine-containing polymers, silicon-containing polymers, and a
combination thereof. Furthermore, the modifier may include a
hydrophobic oil-proof agent for enabling the at least one modified
fiber to be hydrophobic and oil proof. The hydrophobic oil-proof
agent is preferably but not limited to polytetrafluoroethylene.
Moreover, the modifier may include a sunlight resistant agent for
enabling the at least one modified fiber to be sunlight resistible.
The sunlight resistant agent is preferably but not limited to a
material selected from a group consisting of a UV absorbent, an
infrared ray absorbent, a metal oxide, and a combination
thereof.
[0018] Step 1050, a step of spinning the raw fibers and the at
least one modified fiber into a mixed yarn is performed. More
particularly, the raw fibers is spun with the at least one modified
fiber into the mixed yarn with a ratio of 1% to 99%, wherein the
mixed yarn may be spun with a variety of counts. Moreover, since
the at least one modified fiber is modified from the at least one
raw fiber, the composition of the mixed yarn is 100% raw fiber.
[0019] The advantage of the yarn manufacturing method of the
present invention is described as below. As shown in FIG. 1, in the
embodiment, the yarn manufacturing method further include step
1070, a step of dyeing the mixed yarn. For example, in a case of
using the cation modifier as the modifier, only the modified fiber
is dyeable when the mixed yarn is dyed with the acid dye.
Therefore, the dyed mixed yarn will have fleck fancy effect,
wherein the fleck color depends on the acid dye used in the dyeing
step. In other words, in this embodiment, the fleck color of the
fleck fancy mixed yarn manufactured according to the yarn
manufacturing method of the present invention can be changed by
changing the acid dye used in the dyeing step. It eliminates the
need of preparing pre-dyed fibers in advance and then spinning raw
fibers with the pre-dyed fibers as described in the conventional
method.
[0020] In different embodiments, the steps of the yarn
manufacturing method of the present invention are modified under
the same concept. A flow chart of a second embodiment is shown in
FIG. 2, wherein the yarn manufacturing method includes the
following steps.
[0021] Step 2010, a step of providing at least one modified fiber
which is modified from at least one raw fiber is performed.
[0022] Step 2030, a step of providing the at least one raw fiber is
performed.
[0023] Step 2050, a step of spinning the at least one raw fiber and
the at least one modified fiber into a mixed yarn is performed.
[0024] More particularly, in the first embodiment, a plurality of
raw fibers is provided first. After that, at least one of the raw
fibers is modified to form at least one modified fiber and then the
raw fibers and the at least one modified fiber are spun into a
mixed yarn. In the second embodiment, the modified fibers are
directly provided, commercially purchased for example, to be spun
with the raw fibers into a mixed yarn. Moreover, the modified
fibers could be modified from first row fibers and then be spun
with second raw fibers into a mixed yarn.
[0025] Although the preferred embodiments of the present invention
have been described herein, the above description is merely
illustrative. Further modification of the invention herein
disclosed will occur to those skilled in the respective arts and
all such modifications are deemed to be within the scope of the
invention as defined by the appended claims.
