Problems solved by technology

Therefore, some factories have too high a density in the fabric design, so that the fabric shrinks too much after wet processing, and the fabric feels hard; some weaving widths are too small. , the fabric style cannot be expressed; some weaving widths are too large, the density is too small, and the heat setting stretch is too small, which cannot further improve the elasticity of the fabric and form an ideal fabric style

Embodiment 1

[0013] Embodiment 1: use 68D PET filament as warp yarn, use A100 tencel as outer covering fiber, take the DTY filament of PTT 75D as the plain weave fabric based on ring-spinning core-sheath type core-spun yarn as weft yarn.

[0014] Immerse the fabric in a rope-mounted dyeing machine with a treatment bath of 0.5% (relative to fabric weight) penetrating agent JFC (a non-ionic surfactant), heat up and run, heat up to a specified temperature of 80°C, keep the temperature and continue to run 15 minutes, at this time, the weft shrinkage rate of the fabric is about 5%; the wet cloth is out of the machine, and the elongation of the door width is stretched to 4% on the heat setting machine, and the heat setting machine is heated at 160°C at a speed of 10-15 m / min. . The elastic recovery rate of the thus processed fabric is increased from 74.35% to 82.34% of that of the room temperature water-washed fabric without shrinkage and stretch setting, and the breaking strength is increased f...

Embodiment 2

[0016] A plain weave fabric based on ring-spun core-sheath core-spun yarn with 60s A100 Tencel as the warp yarn, A100 Tencel as the outer fiber, and PTT 75D DTY filament as the weft yarn. A100 Tencel 60s warp must be sized before weaving.

[0017] The fabric is immersed in 0.5% (relative fabric weight) penetrating agent JFC (a kind of non-ionic surfactant), Na 2 CO 3 5g / L, desizing and scouring agent 4g / L (a kind of compound preparation of surfactant), in the rope-mounted dyeing machine of the treatment bath, heat up and run, heat up to the specified temperature 100°C and keep the temperature for 30 minutes. The weft shrinkage rate of the fabric is about 7%; the wet cloth is out of the machine, stretched on the heat setting machine to an elongation of 6.5%, and enters the heat setting machine at a speed of 10-15 m / min at 160°C for heat treatment. The elastic recovery rate of the fabric thus processed is increased from 74.35% to 79.55% of that of the fabric without shrinkage ...

Embodiment 3

[0019] Plain weave fabric with 68D PET filament as the warp and 75D PTT filament and 60s Tencel yarn network as the weft yarn.

[0020] Immerse the fabric in an overflow dyeing machine with a treatment bath of 1g / L (relative to fabric weight) penetrating agent SP-2 (a non-ionic surfactant), heat up and run, heat up to a specified temperature of 80°C and keep The temperature continues to run for 15 minutes. At this time, the weft shrinkage rate of the fabric is about 8%; the wet cloth is taken out of the machine, and the elongation of the width is stretched to 4% on the heat setting machine, and the heat setting machine is entered at a speed of 10-15 m / min. Heat treatment at 170°C. The weft elastic recovery rate of the thus processed fabric is increased from 75.74% to 82.69%, and the breaking strength is increased from 339.30N to 391.50N.

Abstract

The invention discloses a stress adjustment elasticized heat treatment process for PTT filament compound fabrics, comprising: wetting a cloth of fabric before heating setting to make the fabric be shrunk by four percent to fifteen percent, and then stretching the fabric by two percent to ten percent along warp direction or latitudinal direction, then eliminating the internal stress by heat treatment so that the internal structure of PTT fiber will reset with elastic recovery percentage raised and fiber structure and fabric size stabilized. In the meanwhile, changes of fabric structure and width size caused by the stress adjustment course can provide a basis for fabric design and formation of fine style of fabrics.

Description

Technical field: [0001] The invention relates to a stress regulation and elastic heat treatment process of textiles, in particular to a stress regulation and elastic heat treatment process of PTT filament composite fabric. Background technique: [0002] The development trend of textile fabrics is to compound various fibers in various ways, or blend short fibers, or compound filaments and short fibers in various ways to form complementary advantages, so that the excellent characteristics of various fibers can be best utilized. PTT filament composite fabric can fully system the elastic characteristics of PTT fiber, and combine the advantages of PTT fiber and other filament or short fiber to form excellent fabric performance. [0003] PTT fiber is made of polypropylene terephthalate, which is a new type of polyester textile fiber material with excellent elasticity, softness and dyeing properties. As a thermoplastic fiber, PTT fiber will shrink when heated, even in the process ...
