Problems solved by technology

However, fabrics with knitted fabric structure have relatively low UV protection coefficient.
In addition, when clothes made of general polyester fabrics are worn in hot weather in summer, due to the low thermal conductivity of polyester fibers, the body will feel stuffy, which reduces the wearing comfort of the products.

Abstract

The invention discloses a method for manufacturing an ultraviolet-proof polyester knitted fabric. The method comprises the following steps: 1) selecting a polyester knitted fabric of which the ultraviolet protection factor is smaller than 30, and the air permeability value is 3200-3500mm / s as a base material layer; 2) taking 10-12g / L foam stabilizer, 65-70g / L nano titanium dioxide powder, 10-15g / L foaming agent, 75-80g / L xylitol cool feeling processing agent, 100-120g / L waterborne polyurethane and 20-25g / L crossing agent to prepare water-based coating glue; 3) foaming the water-based coating glue at a foaming ratio of 15-20 times by using a foaming machine; 4) coating the foamed foam glue on the surface of one side of the base material layer according to 25-30g / m<2>, so as to form a water-based foam coating; 5) drying the coated base material layer inside an oven at 100-110 DEG C for 5-8 minutes; and 6) compacting the water-based foam coating by a pinch roller, so as to obtain the finished product. The ultraviolet-proof polyester knitted fabric manufactured by the method is high in air permeability value, large in ultraviolet return protection factor and large in coefficient of heat conduction.

Description

technical field [0001] The invention relates to a method for manufacturing an anti-ultraviolet polyester knitted fabric. Background technique [0002] The summer sun has strong ultraviolet rays, and clothing needs relatively good anti-ultraviolet capabilities. However, fabrics with knitted fabric structure have relatively low UV protection coefficient. In addition, when clothes made of general polyester fabrics are worn in hot weather in summer, due to the low thermal conductivity of polyester fibers, the body will feel stuffy, which reduces the wearing comfort of the products. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing an anti-ultraviolet polyester knitted fabric. The anti-ultraviolet polyester knitted fabric produced has high air permeability, large ultraviolet return protection coefficient, and large heat transfer coefficient. [0004] In order to achieve the above object, the technical solution of t...
