Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the polyester with waterproof function needs to be processed in two steps of dyeing process and waterproof finishing in the prior art. A one-bath one-step processing method for polyester dyeing and waterproof finishing, which shortens the processing cycle, saves energy and reduces consumption, saves water resources, improves the utilization rate of equipment and the production efficiency of workers, and at the same time meets the requirements for dyeing fastness, and has good waterproof effect and washability
[0005] The second technical problem to be solved by the present invention is the poor waterproof performance of fabrics caused by fabrics and impurities. For thin fabrics with high count, high density, low grammage and low liquid rate, etc., which are difficult to waterproof and spinning oil The fabrics that seriously affect the waterproof effect such as unclean agent removal, insufficient pre-treatment scouring, insufficient washing after dyeing, etc., the present invention can obtain good waterproof effect on the above-mentioned types of fabrics, which is generally better than the post-finishing method
[0006] The third technical problem to be solved by the present invention is to improve the rough and hard hand feeling of the fabric after waterproof finishing, and solve the problem of mutual influence between waterproof finishing and softener in the traditional finishing process

Abstract

The invention relates to a one-bath one-step processing method for dyeing and waterproof finishing of a polyester fabric. The method of the invention comprises starting dyeing at room temperature, soaking the polyester fabric to be dyed in a working fluid, heating gradually to a working temperature, holding the temperature, carrying out dyeing and waterproof finishing at the same time, cooling tocomplete the dyeing and waterproof finishing, subjecting the fabric to reductive cleaning, and carrying out acid neutralization, water washing and baking. The conventional dyeing and post-finishing stepwise processing method is broken through; the dyeing and finishing process is shortened; production cost is reduced; emission of wastewater is reduced; the method of the invention has high production efficiency and good environmental friendliness, as well as good economic and social benefits, and is important to the development of clean dyeing and finishing and ecological textiles.

Description

technical field [0001] The invention belongs to the field of dyeing and finishing of textile fabrics, and in particular relates to a one-step processing method for polyester fabric dyeing and waterproof finishing in one bath. Background technique [0002] Functional textiles are increasingly attracting great attention and favor from people, among which waterproof / hydrophobic textiles are widely used in sports and leisure fabrics, outdoor protective clothing, tents, umbrella cloth and other fields due to their excellent and unique properties. Polyester has high breaking strength, elastic modulus and good washability and wearability, so it has become one of the fastest growing and most widely used varieties of synthetic fibers. Afterwards, waterproof / hydrophobic finishing is carried out. At present, dyeing and waterproof / hydrophobic finishing are two independent processes in the industrial production process. At the same time, in order to achieve a good waterproof effect, it ...
