Embodiment 1

[0026] Step 1. Yarn preparation

[0027] Weft thread: Use a super pulverizer to pulverize cotton linters, the pulverized particle size is less than 2.5mm, dissolve to a mass fraction of 90% NMMO solution, the dissolution temperature is 120°C, and the dissolution reaction is 1 hour. Dehydration by padding, filtration, nano-grinding, incorporation into PET, and melting to make porous triangular polyester with a fineness below 1.0D.

[0028] Warp: Porous fine-denier different-faced polyester made by PET melt-spinning method, with a fineness of less than 1.0D.

[0029] Step 2, warping: Warp the warp yarns in batches, wind them into pulp shafts, and warp at a speed of 500 m / min;

[0030] Step 3, sizing: the warped yarn is soaked in the size tank through the size tank, the mass fraction of the dissolved modified starch in the slurry is 20%, the mass fraction of the polyacrylate size is 25%, the temperature is 95°C, and the sizing rate is 6 -8%; and then dried in a drying room, the...

Embodiment 2

[0036] Step 1. Yarn preparation

[0037] Weft: Use a super pulverizer to pulverize cotton linters with a mass fraction of 90% and sisal hemp with a mass fraction of 10%. The particle size of the pulverized particles is less than 2.5mm, and then dissolved to a NMMO solution with a mass fraction of 90%. The dissolution temperature is 120°C and the dissolution reaction is carried out for 1 hour. Dehydration by padding, filtration, nano-grinding, incorporation into PET, and melting to make porous triangular polyester with a fineness below 1.0D.

Abstract

The invention provides a preparation method of silk-like fabric, which comprises the steps: selecting natural cellulose and modified polyester, preparing yarns, warping, sizing, drafting, weaving anddesizing to obtain the silk-like fabric. The silk-like fabric retains the advantages of good hygroscopicity, high melting resistance, heat insulation and antistatic property in natural cellulose, andalso has the performances of stable size and high elasticity in polyester, and in addition, the fabric far exceeds the natural silk in terms of gloss and hand feeling. The preparation process of the method is simple, the cost is low, and a product with high added value can be attained. The method is suitable for large-scale popularization in industry.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a simulated silk fabric and a preparation method thereof. Background technique [0002] Silk is composed of protein fibers, has good biocompatibility with the human body, soft and smooth texture, low friction coefficient, and good wearability. Silk monofilament has a very small fiber fineness and its own hollow structure is easy to distribute water, can absorb moisture in the air, has a certain water-locking performance, and makes the skin feel refreshed and not dry in a dry environment. Under the high temperature conditions in summer, silk has good moisture dissipation performance, making people cool and comfortable to wear. It contains 18 kinds of amino acids needed by the human body, supply the needed "nutrition" to the skin, and provide health care and skin care. However, the production area and output of real silk are always limited, and the cost is relatively high, whi...
