Problems solved by technology

Due to the poor weather resistance, temperature resistance and dyeing and finishing performance of spandex fiber, especially the resistance to environments containing chlorine (such as swimming pools), elastic fabrics are usually worn for one year or even stored for one year. It will lose its elasticity and produce loose deformation and other phenomena.

Embodiment 1

[0036] A composite elastic filament core-spun yarn fabric, the preparation steps of which are as follows:

[0037] A. Core-spun yarn spinning: 50dtex / 24f PTT / PET parallel composite elastic filaments are introduced into the front roller of the spinning frame, and the weight ratio of PTT:PET in the PTT / PET parallel composite elastic filaments is 50:50, and PTT / PET is parallel The cross-section of the composite elastic filament is racetrack-shaped. The long-staple cotton is used as the outsourcing fiber, and the roving is introduced from the drafting device of the spinning frame, meets the elastic filament at the front roller, and is twisted to form a core-spun yarn.

[0038] At the front roller of the ordinary spinning frame, the positioning device controls the elastic filament to be located in the center of the twisting triangle to achieve the most uniform cotton fiber covering; the PTT / PET side-by-side composite elastic filament controls the initial tension through a tension c...

Embodiment 2

[0046] A composite elastic filament core-spun yarn fabric, the preparation steps of which are the same as in Example 1 except for the following differences.

[0047] The warp is wool / polyester 70 / 3090Nm / 2. Single yarn twist is 820 twists / m, Z direction, ply twist is 1000 twists / m, S direction. The weft yarn is 50dt / 36f PET / PTT side-by-side composite elastic filaments (the weight ratio of PET:PTT is 60:40) outsourcing combed wool slivers to form 90Nm elastic core-spun yarn, and then plying into strands. The cross-section of the PTT / PET side-by-side composite elastic filaments is flat. In the core-spun yarn, the weight ratio of PTT / PET side-by-side composite elastic filaments to wool fibers is 45:55. Single yarn twist is 820 twists / m, Z direction, ply twist is 1000 twists / m, S direction. In order to prevent the yarn from kinking under the action of untwisting torque, the yarn was steamed at 75°C for 30 minutes and cooled for 5 minutes. No. 139 reed is used for weaving, with ...

Embodiment 3

[0050] A composite elastic filament core-spun yarn fabric, the preparation steps of which are the same as in Example 1 except for the following differences.

[0051] Warp yarn is long-staple cotton 40S / 2 yarn. Single yarn twist: 900 twists / m, Z direction, ply twist: 880 twists / m, S direction. The weft yarn is 40dt / 36f PET / PTT side-by-side composite elastic filaments, in which the weight ratio of PET:PTT is 40:10, which is wrapped with combed long-staple cotton to form 40S elastic core-spun yarn, and then plied into strands. The cross-section of the PTT / PET side-by-side composite elastic filaments is flat. In the core-spun yarn, the weight ratio of PTT / PET side-by-side composite elastic filaments to cotton fibers is 30:70. Single yarn twist is 850 twists / m, Z direction, ply twist is 880 twists / m, S direction. In order to prevent the yarn from twisting under the action of untwisting torque, the yarn was steamed at 70°C for 20 minutes and cooled for 5 minutes. No. 130 reed is...

Abstract

The invention relates to a composite elastic filament core-spun yarn fabric and a preparation method thereof. The wefts of the composite elastic filament core-spun yarn fabric are elastic filament core-spun yarns, the warps of the composite elastic filament core-spun yarn fabric are elastic filament core-spun yarns or non-elastic yarns, and the elastic filament core-spun yarn is prepared from a PTT(polytrimethylene terephthalate) / PET (polyethylene terephthalate) parallelly composite elastic filament serving as a core yarn and natural fibers and / or chemical fibers serving as coating fibers, wherein the weight ratio of the core yarn to the coating fiber is (3:7)-(7:3). The weft flotation line of the fabric has 1-4 intersection points, and the fabric is prepared by virtue of a core-spun yarn spinning process, a weaving process and a dyeing and finishing process. The fabric is prepared by coating the PTT / PET parallelly composite elastic filament with cotton fibers and the like with good comfortability, thereby meeting the requirements of elasticity and comfortability. In the subsequent processing and using of the fabric, the elastic structure of the product provided by the invention is not destroyed by mechanical, thermal and chemical conditions. Therefore, the product provided by the invention has the advantage of durable weft-direction elasticity.

Description

technical field [0001] The invention relates to an elastic filament core-spun yarn fabric and a preparation method thereof, in particular to a latitudinal elastic fabric with PTT / PET side-by-side composite elastic filament core-spun yarn as a weft yarn and a preparation method thereof, which belongs to the field of textile technology. Background technique [0002] Traditional elastic yarns are mostly prepared by using spandex filaments to outsource other fibers such as cotton fibers. Due to the poor weather resistance, temperature resistance and dyeing and finishing performance of spandex fiber, especially the resistance to environments containing chlorine (such as swimming pools), elastic fabrics are usually worn for one year or even stored for one year. It will lose its elasticity, resulting in relaxation and deformation. [0003] In view of this, providing a fabric with lasting elasticity and its preparation method has become an urgent problem in this technical field. ...
