Example Embodiment

[0086] Example 1

[0087] Thermoplastic polyurethane meltblown elastic non-woven fabric layer: 30g / m is selected in this embodiment 2 The thermoplastic polyurethane meltblown elastic non-woven fabric (ZP901-30) is used to produce anti-drilling velvet fabric. The thickness of the thermoplastic polyurethane meltblown elastic non-woven fabric is 0.11mm, and the fiber diameter is 8-30μm. To test the warp and weft tear strength and breaking strength of the non-woven fabric layer, use a fabric breaking strength tester, model TH-8203S, manufacturer Suzhou Tuobo Machinery Equipment Co., Ltd., the results are shown in Table 2, using the maximum magnification of 1000 Measure the diameter of multiple micropores on the cloth surface with a magnification electron microscope, it can be seen that the maximum pore diameter between fibers is in the range of 20-60μm.

[0100] Example 2

[0101] Thermoplastic polyurethane meltblown elastic non-woven fabric layer: 30g / m as described in Example 1 is selected in this embodiment 2 The thermoplastic polyurethane meltblown elastic non-woven fabric is used to produce composite swimwear fabrics.

[0102] Elastic knitted base fabric: select polyester low-stretch yarn (DTY) 20D / 24F as raw materials to weave on a 32-needle warp knitting machine to obtain an elastic knitted base fabric, and weave 1-3 / 2-0 / / with heavy warp plain weave , The width of the upper machine is 180 inches and the double width is opened (single width is 228.6cm), and the weft density of the upper machine is 21 turns / cm.

[0103] The grey fabric after the machine needs to be dyed by overflow before shaping. When shaping, you can add softener and water repellent to the rolling groove for water repellent softening treatment. The shaped width is 153-154cm, and the warp and weft are dense (17-18) x(27-28 circle) / cm, the square gram weight is...

[0108] Example 3

[0109] Thermoplastic polyurethane meltblown elastic non-woven fabric layer: 30g / m as described in Example 1 is selected in this embodiment 2 The thermoplastic polyurethane meltblown elastic non-woven fabric is used to produce sun-proof outdoor sports fabrics.

[0110] Elastic knitted base fabric: In this embodiment, the elastic knitted base fabric described in Embodiment 1 is selected.

[0111] Composite: The method is the same as in Example 1 except for the amount of coating. Coating amount 8.5g / m 2 .

[0112] Low-temperature dyeing and sun protection: Use low-temperature disperse dyes to dye composite fabrics under slightly acidic conditions at 110°C. After low-temperature dyeing, add 15-30g / l of ultraviolet absorber (Sunlife LPS-980NZ of Nikka Company) in the rolling tank when drying and setting in the subsequent setting machine, the padding rate is 75-90%, and the air-dry setting temperature is 120 -130°C. After this treatment, the protective effect above SPF...

Abstract

The invention relates to a composite fabric as well as a preparation method and application thereof. The composite fabric comprises a thermoplastic polyurethane molten spray elastic nonwoven fabric layer and an elastic knitted base cloth layer which are subjected to point compounding through wet gas curing reaction type polyurethane hot melt adhesives. The composite fabric has good elasticity andwear-resistant performance; the problem of poor anti-tearing performance of the thermoplastic polyurethane molten spray elastic nonwoven fabric layer is solved by the knitted base cloth; through the thermoplastic polyurethane molten spray elastic nonwoven fabric layer, the loop fracture scattering possibility of the knitted base cloth during the great external force stretching can be reduced; thestress problem incapable of being solved by a single fabric is solved. The composite fabric provided by the invention can meet the use requirement in special environment; the method is suitable for being used for preparing down proof fabrics, swimsuit fabrics or outdoor sports fabrics.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a composite fabric and its preparation method and application. Background technique [0002] The molecular structure of polyurethane is composed of soft and hard segments, which can endow textiles with high elasticity. It has two common forms in fabrics or composite fabrics: one is silk (spandex) spun from polyurethane by dry or wet method and other fibers are wrapped into composite silk weaving or with other fibers The other is to use the thermoplastic polyurethane (TPU) film's waterproof, moisture-permeable and air-proof function, and combine it with knitted or woven elastic fabrics, which can be windproof, waterproof, moisture-permeable, and anti-drilling. [0003] However, both forms of polyurethane elastomer-containing textiles have some disadvantages. For example, for blended or interwoven fabrics containing spandex, monofilament spandex is difficult to dye with other fi...
