Problems solved by technology

The structure of the yarn spun by the former is that polyester fibers and non-polyester fibers are entangled with each other, and the uneven blending is very easy to cause uneven dyeing in the subsequent fabric; the latter uses filament spinning, and the cost price is relatively high.

Embodiment 1

[0040] A production process of elastic yarn, such as figure 1 shown, including the following steps:

[0041] 1) The polyester staple fiber roving 3 spun by polyester staple fiber and another group of staple fiber roving 2 for coating the staple fiber spinning outside are respectively placed on the hanging spindle 1 of the spinning frame; wherein the polyester staple fiber Fiber roving 3, average length 16-51mm, roving weight 5.6g / 10m, design twist 4.87; staple fiber roving 2, average length 16-60mm, roving weight 5.6g / 10m, design twist 4.87;

[0042] 2) Then the polyester staple fiber roving 3 in step 1) enters between the front roller 11 and the front top roller 12 after passing through the guide hook 4, bell mouth 5, rear top roller 7, and middle iron roller 9 successively; The fiber roving 2 passes through the guide hook 4, bell mouth 5, rear roller 6, and middle roller 8 in sequence, and then enters between the front roller 11 and the front top roller 12; wherein, the bel...

Embodiment 2

[0047] The warp yarn is C16S, the weft yarn is T / C50 / 5016S+40D Lycra 3.5 elastic yarn, the twill weave is 2 up and 1 down, and it is woven on a rapier loom. The weaving warp density is 45 pieces / inch, and the weft density is 40 pieces. / inch.

Embodiment 3

[0051] The warp yarn is C21S slub, and the weft yarn is T / C50 / 5021S+70D Lycra 4.0 elastic yarn. It is woven on a rapier loom with a plain weave of 1 up and 1 down. The weaving warp density is 57 threads / inch and the weft density It is 52 / inch.

Abstract

The invention discloses an elastic yarn, and belongs to the technical field of textile engineering. The yarn comprises a group of elastic core fibers, a group of polyester staple fibers and a group ofstaple fibers coating on the outermost layer, the elastic core fibers and the polyester staple fibers are drafted and are output by a front roller with the staple fibers used for coating, twisting and winding are carried out to form the yarn with the polyester staple fibers and the elastic core fibers inside and other staple fibers outside. According to the invention, the polyester staple fiber roving is drafted and twisted with another staple fiber roving, and meanwhile, the elastic core fibers are fed, so that the elastic yarn which has the advantages of easy dyeing, excellent elasticity, abrasion resistance, pilling resistance, water washing resistance and water retention property is produced; the elastic yarn is used as a weft yarn, the warp yarn is not limited, the elastic recovery rate of a woven fabric is high, the elastic recovery rate of the weft is between 55-85%, the abrasion and pilling grade of the woven fabric is 3.5-5, and the wrinkle recovery performance grade is 4-5.

Description

technical field [0001] The invention relates to an elastic yarn, a production process and its fabric, and belongs to the technical field of textile engineering. Background technique [0002] Polyester fiber has excellent textile performance and wearing performance, and is widely used. The spun fabric has good wrinkle resistance and shape retention, is easy to wash and dry, and has high strength, so it has excellent wear resistance and anti-pilling performance. However, the antistatic performance of the fabric is poor. Non-polyester staple fibers, such as natural fibers such as pure cotton and wool, are soft to the touch and comfortable to wear, but are prone to pilling and poor wrinkle resistance. The blending of polyester staple fiber and non-polyester staple fiber makes up for the shortcomings of blended materials, and improves the fabric comfort, shape retention, washing resistance and other properties, so it is very popular among consumers. [0003] Polyester materials...
