Title:
FLAME-RETARDANT KNITTED FABRIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/123391
Kind Code:
A1
Abstract:
A flame-retardant knitted fabric and a preparation method therefor. The flame-retardant knitted fabric is prepared from flame-retardant textile fibers by means of a knitting process. The flame-retardant textile fibers are prepared by mixing spandex, flame-retardant polyester fibers, and flame-retardant cotton fibers according to a weight ratio and then spinning. In the preparation process of the flame-retardant polyester fibers, a layer of sericin is attached to the surface of the polyester fibers, so that skin friendliness of the polyester fibers can be improved, and the polyester fibers have good air permeability and water conductivity. In the preparation process of the flame-retardant cotton fibers, inorganic salt modified montmorillonite is taken as a modifier, isocyanate is taken as a grafting agent, and single crystal wafers of the inorganic salt modified montmorillonite are grafted and fixed on the surface of the cotton fibers, so that air permeability and water absorption effects of the cotton fibers are not affected, the single crystal wafers of inorganic salt modified montmorillonite can also be uniformly grafted on the cotton fibers, and flame-retardant performance of the cotton fibers is improved. The present solution improves the flame-retardant performance of the fabric, without affecting the strength and skin friendliness of the fabric.
