Problems solved by technology

The current far-infrared fabrics usually use the impregnation method to adhere or absorb the far-infrared materials on the fabric fibers, resulting in insufficient bonding and poor durability, and there is no product that blends tencel fibers and far-infrared fibers.

Embodiment 1

[0029] Preparation of far-infrared ultrafine powder:

[0030]

[0031] After mixing the above components, the mixture is ground into a far-infrared ultrafine powder with an average particle size of ≤0.4 microns and a maximum particle size of ≤0.5 microns by a jet mill.

[0032] Preparation of far infrared masterbatch:

[0033] The far-infrared ultrafine powder is blended and dried with the fiber base material, added with a polymer spinning aid, and then entered into a screw extruder for melting, blending and extruding, and granulated to obtain a far-infrared masterbatch; the fiber base material and the far-infrared ultrafine The weight ratio of micropowder is 100:5;

[0034] Far infrared fiber production:

[0035] After the far-infrared masterbatch and fiber chips are blended, the Tencel blended yarn is formed after spinning, winding and stretching. The far-infrared masterbatch and fiber chips are mixed in a mass ratio of 1:10.

[0036] Tencel blended yarn production pr...

Abstract

The invention discloses a preparation method for a tencel blended yarn. Tencel fibers and far infrared fibers are blended sequentially through the procedures of opening and cleaning, carding, drawing, roving and spinning to form the tencel blended yarn, the weight content of the tencel fibers accounts for 60-65 percent of the tencel blended yarn, and the weight content of the far infrared fibers accounts for 35-40 percent of the tencel blended yarn; the far infrared fibers are prepared through the following method: far infrared ultrafine micro powder and fiber basic material are mixed and dried, a polymer spinning aid agent is added to the mixture, the mixture is fed to a screw-type extruder and is subjected to melt blending extrusion and granulation, and then far infrared master batch is obtained; the far infrared master batch and fiber chips are blended, spun, wound and stretched to form the far infrared fibers. The tencel blended yarn produced through the preparation method for the tencel blended yarn, disclosed by the invention, combines the health and environmental-protection characters of the tencel fibers with the warm-keeping effect of the far infrared fibers, has the advantages of natural property, environmental protection and warm keeping and the like, and is applicable to garment fabric and other industries.

Description

technical field [0001] The invention relates to a preparation method of Tencel blended yarn. Background technique [0002] Tencel fiber is a high wet modulus regenerated cellulose fiber produced by wet spinning after dissolving cellulose in an aqueous solution of N-methoxymorpholine (NMMO for short). The production is carried out in a closed system, and the recovery rate of organic solvent NMMO can reach more than 99%, which is harmless to the environment. Therefore, Tencel fiber is a green and environmentally friendly fiber. [0003] Cellulose is a renewable natural resource, which is sustainable and environmentally friendly. It can participate in the ecological cycle of nature. At the same time, it has excellent hygroscopicity and wearing comfort. Therefore, cellulose fiber is the most ideal and promising textile in the new century. one of the raw materials. Tencel fiber is a new type of cellulose fiber with the highest degree of industrialization at present, and it has...
