Embodiment 1

[0059] Now the glue treatment process is carried out according to the following steps:

[0060] (1) Addition of block-type linear polymer: add block-type linear polymer by 0.8% glue weight, stir to make it even;

[0061] (2) Defoaming: Put the prepared glue solution into a container and vacuumize it for defoaming treatment. Time 50-60 minutes;

[0062] (3) Spinning: Spinning, plasticizing and stretching through an acidic coagulation bath;

[0063] (4) Water washing: wash the silk twice with 40°C-45°C water;

[0064] (5) Desulfurization: NaOH is used for desulfurization treatment, the dosage is 3 g / L, and the temperature is 40°C-45°C;

[0065] (6) Water washing: wash the desulfurized filament twice with water at 40°C-45°C;

[0066] (7) Drying: use mesh curtain circulating air to guide the flow, the drying temperature is 75°C-85°C, and the drying time is 20 minutes;

[0067] (8) cut off: long filament is cut into 51mm length;

[0068] (9) Fiber surface treatment:

Abstract

The invention relates to a technique for changing the characteristics of regenerated cellulose fibre. The method mainly comprises the following steps: using the copolymerization characteristic of hydroxyl groups of the surface of the cellulose fibre and active groups in the filler, combining the solution before filamentization and a block type linear polymer, being capable of improving the degree of orientation of fibre crystallinity after spinning and solidification, and then using the mechanical performance to stretch along the orientation direction so as to enhance the elasticity of the regenerated cellulose fibre, improve the defects of poor elastic recovery thereof and improve the wet strength thereof; and then using a softening agent to treat the surface of the fibre, thus improving the hand feel characteristic of the cellulose fibre, and leading the cellulose fibre to have smooth and soft hand feel effect. The technique has the effects of: leading the surface of the fabric prepared by the modified cellulose fibre to achieve the effect of no microfibrillation, having falling and swinging motion, light and soft touch, good fastness and durable color, being capable of improving the smooth hand feel of the fabric when being blended with cashmere, having more comfortable wear and being excellent material of textiles used for various clothes and decoration.

Description

technical field [0001] The invention belongs to the textile field and relates to a process for changing the properties of regenerated cellulose fibers. Background technique [0002] Regenerated cellulose fiber is an important raw material in the textile industry. The textiles made of it have good hygroscopicity, are comfortable to wear, and have excellent spinnability. They are often blended and interwoven with various cotton, wool or various synthetic fibers for various Apparel and decorative textiles. However, its wet strength is low, it is easy to deform under a small load, and its elastic recovery performance is poor, so the fabric is easy to elongate and its dimensional stability is poor. And the drape is not good, and the hand feel is not smooth. The invention utilizes the copolymerization characteristics of the hydroxyl group on the surface of the cellulose fiber and the active group in the filler, and combines the solution before filamentation with a block-type lin...
