preparation example Construction

[0038] The embodiment of the present invention also provides a method for preparing a skin-friendly and breathable double-layer velvet cotton fabric, comprising the following steps:

[0039] Step 301, blending modified cotton fibers and mulberry silk to form a modified cotton layer.

[0040] Step 302, weaving the modified polyester fibers as warp and weft yarns to form a modified polyester layer.

[0041] Step 303, using an adhesive to bond the modified cotton layer and the modified polyester layer together to obtain the skin-friendly and breathable double-layer velvet cotton fabric.

[0042] In the embodiment of the present invention, the adhesive may be water-based glue, for example, JL-8261 water-based self-adhesive, JL-606 dry-type water-based laminating adhesive, and the like.

Embodiment 1

[0045] The skin-friendly and breathable double-layer velvet cotton fabric in the present embodiment is prepared by the following method:

[0046] Prepare the modified cotton layer: freeze-dry the cotton fiber and pulverize it, disperse the pulverized cotton fiber in cobalt hydroxide / sulfolane solution, react at 80°C for 1 hour, cool, filter, wash 3 times and then freeze-dry to obtain Modified cotton fibers;

[0047] The modified cotton fiber and mulberry silk are used for blending to form a modified cotton layer.

[0048] Preparation of modified polyester layer: polyester is used as raw material, sliced, dried, and melted to obtain a melt; the melt is mixed with sodium dihydrogen phosphate for blending and spinning, and post-processed to obtain a polyester copolymer modified with surface micropores. Blended fibers; the temperature of blended spinning is controlled at 280°C, and the pressure is 7MPa;

[0049] The polyester blended fiber modified by surface micropores was immers...

Embodiment 2

[0054] The skin-friendly and breathable double-layer velvet cotton fabric in the present embodiment is prepared by the following method:

[0055] Prepare the modified cotton layer: freeze-dry the cotton fiber and pulverize it, disperse the pulverized cotton fiber in cobalt hydroxide / sulfolane solution, react at 90°C for 1 hour, cool, filter, wash twice and freeze-dry to obtain Modified cotton fibers;

[0056] The modified cotton fiber and mulberry silk are used for blending to form a modified cotton layer.

[0057] Preparation of modified polyester layer: polyester is used as raw material, sliced, dried, and melted to obtain a molten liquid; mixed with sodium dihydrogen phosphate and potassium dihydrogen phosphate in the molten liquid for blending and spinning, and post-processing to obtain micropores on the surface Modified polyester blended fiber; the temperature of the blended spinning is controlled at 290°C, and the pressure is 6MPa;

[0058] The polyester blended fiber ...

Abstract

The invention belongs to the technical field of materials and provides a skin-friendly breathable double-layer velvet cotton fabric and a preparation method thereof. The fabric comprises a modified cotton layer and a modified polyethyleneterephthalate fiber layer bonded with the modified cotton layer, wherein the modified cotton layer is good in skin friendliness; the modified polyethyleneterephthalate fiber layer is a tatted layer formed by tatting modified polyethyleneterephthalate fibers subjected to surface micropore modification and section special-shaped modification treatment. Through surface micropore modification and section special-shaped modification treatment on the polyethyleneterephthalate fibers, the hygroscopicity and the moisture exhaust performance of the polyethyleneterephthalate fiber layer can be fully improved, and the velvet cotton fabric has very excellent comfort and air permeability.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a skin-friendly and breathable double-layer velvet cotton fabric and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's consumption concepts have also undergone great changes. As the clothing of the second skin of human beings, people have more and more requirements on the skin-friendly, breathable and other functions of the fabrics. come higher. [0003] The existing velvet cotton fabrics are usually interwoven with ordinary polyester and cotton blends. However, ordinary polyester cannot meet people's requirements for clothing fabrics due to its small moisture regain, poor hygroscopicity, poor air permeability, and poor wearing comfort. Index requirements for skin-friendly, breathable and other functions. Contents of the invention [0004] The embodiments of the present invention pr...
