Problems solved by technology

In order to achieve a better waterproof effect, a high concentration of waterproofing agent needs to be added to the setting working solution, and it needs to be baked for a long time at a high temperature above 150°C. The finished fabric is hard, not soft enough, and waterproof The effect is generally around 90 points (AATCC 22), which cannot meet the higher requirements of customers
At the same time, due to the structural characteristics of the knitted fabric coil, it has greater extensibility under the action of external force, so that the shape and size of the coil are easy to change, making it difficult for knitted fabrics to achieve a good waterproof effect.

Abstract

The invention provides a waterproof fabric and a preparation method thereof. The preparation method of the waterproof fabric of the present invention comprises: scouring gray cloth, enzyme washing, dyeing and drying to obtain knitted fabric; treating the knitted fabric with liquid ammonia, and performing neutralization treatment and drying treatment to obtain treated knitted fabric ; Carry out secondary setting to the processed knitted fabric; Carry out pre-shrinking treatment to the cloth sample after setting and finishing to obtain waterproof knitted fabric. The waterproof fabric obtained by the above preparation method has excellent waterproof performance and can be washed for more than 5 times, and meanwhile has soft hand feeling, good dimensional stability and good non-ironing effect.

Description

technical field [0001] The invention relates to a method for preparing a knitted fabric, in particular to a method for preparing a waterproof knitted fabric, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] With the improvement of people's living standards, people's demand for textiles has already changed from simple clothing, wind and cold protection to hygienic, healthy and comfortable functional requirements. Waterproof finishing is to apply one or several finishing agents on the fabric to change the surface properties of the fabric, reduce the surface tension of the fabric, endow the surface of the fabric with a "lotus leaf effect", and make the fabric not easily wetted or stained by water and common oil stains. Sewage. [0003] At present, waterproof finishing is mainly to apply a certain waterproof additive to the cloth surface by dipping and rolling, and then make it cross-linked with the corresponding functional gro...
