Problems solved by technology

[0003] Most of the traditional flame retardants are organophosphorus flame retardants, but the free formaldehyde content in the finished textiles is high, which is harmful to the human body, and the mechanical properties of the textiles have also declined. The traditional finishing methods are to use finishing agents to Textiles are subjected to padding. The textiles finished by this method have poor washability, and the duration of the waterproof and flame-retardant properties of textiles is relatively short.

Embodiment 1

[0023] The preparation method of waterproof flame-retardant textile, comprises the following steps:

[0024] (1) Pretreatment of textiles: Soak the textiles to be treated in clear water, ultrasonic for 10 minutes, take out, dry at 60°C, and set aside;

[0025] (2) Put the pretreated textiles into low-pressure plasma equipment for processing. During the processing, the discharge frequency of the plasma is 20MHZ, and the discharge power is 180W. The front and back sides of the textiles are treated 80 times, and the processing time is 30min. take out for use;

[0026] (3) Mix 3 g of flame retardant, 5 g of polyacrylate, 1 g of crosslinking agent, 1 g of dispersant and 40 g of deionized water, and ultrasonicate for 60 minutes to obtain a waterproof and flame retardant finishing agent;

[0027] (4) Immerse the textile after the plasma treatment into the waterproof and flame-retardant finishing agent obtained in step (3), perform two dipping and two rolling, and the excess rate is ...

Abstract

The invention discloses a preparation method of waterproof flame-retardant textiles. The method comprises the following steps: pretreating the textiles; subjecting the pretreated textiles to plasma treatment; preparing a waterproof flame-retardant finishing agent, soaking the plasma treated textiles in the prepared waterproof flame-retardant finishing agent, and carrying out twice-soaking twice-rolling until the rolling remaining rate is 80%; taking out the textiles, cleaning the textiles with clean water for 2 to 3 times, carrying out drying and carrying out baking, thereby obtaining the waterproof flame-retardant textiles. The waterproof flame-retardant textiles prepared by the method have excellent waterproof and flame retardant properties, are free of off odors, good in washing resistance, free of toxic substances and safe to human bodies and are soft and comfortable.

Description

Technical field: [0001] The invention relates to the technical field of textile finishing, in particular to a finishing method of waterproof and flame-retardant textiles. Background technique: [0002] In recent years, with the rapid increase in the consumption of decorative textiles, the fires caused by textiles are increasing, among which the fires of bedding and home decoration cloth are one of the main reasons. After the burning textiles come into contact with the human body, it will cause skin burns at the slightest level and endanger life at the severest level. During the burning of textiles, a large amount of harmful gases released will also endanger people's health, including various gases such as carbon monoxide, carbon dioxide, hydrogen cyanide and aldehydes, which will cause people to suffocate and die. Therefore, while preventing fires, how to improve the flame-retardant properties of textiles and reduce the losses caused by fires has become an important topic i...
