Abstract

The invention provides a preparation method of a waterproof and cool warp-knitted fabric and the warp knitted fabric prepared by the method. The preparation method comprises the steps of weaving, setting, finishing and dyeing, and forming. In used fiber raw materials, the weight percentage of polyethylene fiber or polyester is 20-100%; the setting comprises waterproof treatment, and the temperature of the waterproof treatment is 100-130 DEG C; and the polyethylene fiber raw material is dyeable polyethylene fiber modified by montmorillonite. According to the invention, cool fibers are innovatively added for an existing waterproof fabric treatment mode, so that the comfort level of the fabric can be improved, and the appropriate, attractive and comfortable performance of the garment fabric can be realized.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing warp-knitted fabric with waterproof and cool feeling function and its product. Background technique [0002] With the improvement of people's quality of life, the demand for fabric functionality has gradually increased. While people are pursuing beauty, their demand for comfort is also increasing. Warm in winter and cool in summer has always been the eternal theme of consumer demand, especially in the field of fibers and fabrics. With the continuous development of cool-feeling fabrics, polyethylene has recently become a key material for cool-feeling fabrics, and there are more and more researches on the modification of polyethylene. [0003] However, the existing polyethylene fiber is difficult to dye, its performance is quite different from that of traditional chemical fibers, and it is difficult to use it at the same time. Contents of the invention [0004] T...
