METHOD FOR MAKING A POLYESTER FABRIC
Abstract
A method for making a polyester fabric includes: (a) providing a
plurality of fibers made from a polyester polymer; (b) spinning the
fibers to form pre-oriented yarns; (c) texturing the pre-oriented
yarns using air textured yarn techniques; (d) warping a portion of
the textured yarns so as to form warp yarns; (e) wefting the
remainder of the textured yarns so as to form weft yarns; and (f)
weaving the warp and weft yarns to form the polyester fabric.

Claims
1. A method for making a polyester fabric having a wool-like
structure, comprising: (a) providing a plurality of fibers made
from a polyester polymer; (b) spinning the fibers so as to form
pre-oriented yarns; (c) texturing the pre-oriented yarns using air
textured yarn techniques so as to form air jet textured yarns
having a fluff-like structure; (d) warping a portion of the air jet
textured yarns on a reel so as to form warp yarns; (e) wefting the
remainder of the air jet textured yarns on another reel so as to
form weft yarns; and (f) weaving the warp and weft yarns so as to
form the polyester fabric.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a method for making a polyester
fabric, more particularly to a method using air jet textured yarn
techniques to form a polyester fabric having a wool-like
structure.
[0003] 2. Description of the Related Art
[0004] Natural fibers include silk, wool and cotton. Wool fibers
have excellent properties, such as water-repellent, hygroscopicity
and dirt-resistance, attributed to their fiber structure. However,
wool production is relatively scarce and expensive.
[0005] Polyester fibers have advantages of easy washing, quick dry,
heat-durability, thermosetting and cost effectiveness. However,
they have a smooth surface and thus lack a wool-like structure.
Therefore, there is a need to produce polyester fibers having a
wool-like or a fluff-life structure.
SUMMARY OF THE INVENTION
[0006] Therefore, the object of the present invention is to provide
a method for making a polyester fabric that can overcome the
aforesaid drawback associated with the prior art.
[0007] According to the present invention, a method for making a
polyester fabric having a wool-like structure comprises: (a)
providing a plurality of fibers made from a polyester polymer; (b)
spinning the fibers so as to form pre-oriented yarns; (c) texturing
the pre-oriented yarns using air textured yarn techniques so as to
form air jet textured yarns having a fluff-like structure; (d)
warping a portion of the air jet textured yarns on a reel so as to
form warp yarns; (e) wefting the remainder of the air jet textured
yarns on another reel so as to form weft yarns; and (f) weaving the
warp and weft yarns so as to form the polyester fabric.
BRIEF DESCRIPTION OF THE DRAWING
[0008] In the drawing which illustrates an embodiment of the
invention,
[0009] FIG. 1 is a flowchart to illustrate consecutive steps of the
preferred embodiment of a method for making a polyester fabric
according to this invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] FIG. 1 illustrates the preferred embodiment of a method for
making a polyester fabric according to this invention.
[0011] The method for making a polyester fabric having a wool-like
structure or a fluff-like structure includes: (a) providing a
plurality of fibers made from a polyester polymer, formation of the
fibers being conducted using extrusion techniques; (b) spinning the
fibers at a high speed ranging from 3000 to 5000 m/min so as to
form pre-oriented yarns (POYs); (c) texturing the pre-oriented
yarns using air textured yarn techniques so as to form air jet
textured yarns (ATYs) having the wool-like structure or the
fluff-like structure; (d) warping a portion of the air jet textured
yarns on a reel (not shown) so as to form warp yarns; (e) wefting
the remainder of the air jet textured yarns on another reel (not
shown) so as to form weft yarns; and (f) weaving the warp and weft
yarns so as to form the polyester fabric.
[0012] Preferably, the polyester polymer is blended with a colorant
so as to form dyed polyester fibers in step (a).
[0013] Preferably, the polyester polymer is made from polyethylene
terephthalate (PET).
[0014] It is noted that since the pre-oriented (i.e., stretched in
a direction) PET yarn has a higher structural strength than that of
a non-oriented PET yarn, the pre-oriented PET yarn can be subjected
to further treatment, such as being textured using the air textured
yarn techniques.
[0015] With the inclusion of texturing the pre-oriented yarns using
air textured yarn techniques in the method of this invention, the
PET fibers thus formed can have a wool-like structure.
[0016] With the invention thus explained, it is apparent that
various modifications and variations can be made without departing
from the spirit of the present invention. It is therefore intended
that the invention be limited only as recited in the appended
claims.
