Method for twisting and covering interchanged spinning
Abstract
The present invention refers to a method for twisting and
covering interchanged spinning. It utilizes a programmed way to
control the ring spinning frame in producing twisted and covered
structures thus spinning composite yarns. The method feeds filament
or staple yarn into different selected positions in the spinning
triangle upon the tension interchange to rapidly spin two different
structured yarns, therefore, enriches variety of the woven fabric
and increase the industrial value.

Claims
What is claimed is:
1. A method for twisting and covering interchanged spinning using a
program to control the mobile mechanism, guiding a filament or
staple yarn into the spinning triangle formed by staple bundles,
wherein the composite yarns are ingeniously woven by way of moving
the mobile mechanism horizontally to feed the filament or staple
yarn into different positions in the spinning triangle and thus
complete the composite yarns of interchanged twisted and covered
structures.
2. The method for twisting and covering interchanged spinning, as
described in claim 1, wherein that feeds filament or staple yarn
that can be dyed in different colors and therefore makes the
composite yarn possess interchanged colors.
3. The method for twisting and covering interchanged spinning, as
described in claim 1, wherein that uses a computer program to
control the frequency and time the mobile mechanism moves
horizontally.
4. The method for twisting and covering interchanged spinning, as
described in claim 1, wherein that uses filament of chemical fiber
or reproduced fiber elements.
5. The method for twisting and covering interchanged spinning, as
described in claim 1, wherein that uses staple yarn of natural
fiber, reproduced fiber elements or chemical fiber.
Description
BACKGROUND OF THE INVENTION
[0001] The spinning of conventional ring spinning frame is mostly
covering and twisting. Generally, as shown in FIG. 1 & FIG. 2,
a yarn guiding wheel is set above the front top roller on the press
arm of the conventional spinning frame to guide the fed filament or
staple yarn (1) into the front roller (6) and out with the staple
bundle. Then through twisting mechanism the bundle is made into
composite yarn. The key to decide whether twisted or covered yarn
depends on the chosen position where the filament or staple yarn is
fed into the spinning triangle (2). When the filament or staple
yarn enters from the outward side of the staple bundle into any
side of the spinning triangle, the twisted yarn (4) is made,
whereas the filament or staple yarn enters from the inward side of
the staple bundle into the central part of the triangle, the
covered yarn (3) is achieved. The frame can work on either position
at a time and structures of the two yarns are simple and lacking
variety.
[0002] The present invention provides with a manufacturing method
to make use of an automatic guiding wheel to change the entering
position of the yarn freely and simultaneously gain the composite
of twisted and covered yarn in the same spinning. Now the features
and advantages of the invention will be described in detail with
reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE INVENTION
[0003] FIG. 1 is a plan view showing a planning to produce covered
yarn.
[0004] FIG. 2 is a plan view showing a planning to produce twisted
yarn.
[0005] FIG. 3 is a plan view showing the production procedure
according to the invention.
[0006] FIG. 4 is a flow chart showing the system control according
to the invention.
[0007] FIG. 5 is a plan view showing the structure of the yarn (A)
produced according to the invention.
[0008] FIG. 6 is a plan view showing the structure of the yarn (B)
produced according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
[0009] As shown in FIGS. 3 & 4, the present invention feeds two
kinds of materials into the ring spinning frame to manufacture
composite yarn, i.e., a method for twisting and covering
interchanged spinning that manufactures product with both twisted
and covered structures in order to enhance additional value. The
materials used include a filament or staple yarn (1) and a staple
bundle (10), which is guided by a set of rollers and then output
from the front roller (6) in a sequence to go through the mobile
mechanism (7) placed in the spinning triangle (2) formed in front
of the front roller by the filament or staple yarn, and the staple
bundle. The spinning triangle is actually built by feeding the
filament or staple yarn, which goes by a mobile mechanism, into the
front roller and together with the staple bundle forming the
triangle where the composite of twisted and covered yarn is
spinned.
[0010] The process is control by a programmed (72) computer (71) to
make the mobile mechanism move horizontally and hence program the
speed of the filament or staple yarn to change the correspondent
positions the filament or staple yarn fed into the spinning
triangle. Respectively, the composite yarn (51) of twisting and
covering structures are produced and twined onto the bobbin (9) by
the snail wire (8).
[0011] Based on the above method, the composite yarn (5)
manufactured by the present invention, as shown in FIGS. 5, 6, is
composed partly of covered structure (51) and twisted structure
(52) of the other part in turns. The rotation is controlled by the
program that moves the mobile mechanism (7) horizontally at a blink
to decide the correspondent position of the filament or staple yarn
(1) when they enter the spinning triangle (2) and eventually gain
the inventive spinning effect.
[0012] In application, the materials can be of different texture
and dyed the interchanged twisted and covered structures in
different colors to make yarns of great variety. In addition, the
length of the twisted and covered structure can be varied with the
frequency and time of the mobile mechanism that is changed by the
program. In this case, more variety of the texture is provided and
the value is increased meanwhile.
[0013] All in all, the method of this present invention is indeed
able to manufacture composite yarns of covered and twisted
structure rapidly and also control in subtlety to achieve products
of great variety. It has tremendous industrial value and absolutely
well-deserved the patent grant.
