Problems solved by technology

[0006] It can be seen from the above that the flame retardants currently successfully marketed are all synthetic chemicals, and there is a problem of releasing free formaldehyde; the newly disclosed natural flame retardant sodium phytate has a good flame retardant effect on silk, but it is The connection between the combustion agent and the silk is achieved through the electrostatic attraction of chitosan and sodium phytate, and its washability is unknown, and the preparation of the conductive silk requires repeated impregnation of chitosan and sodium phytate, which is relatively cumbersome.

Embodiment 1

[0034] (1) Pretreatment of textiles: Soak the cotton fabric to be treated in clear water, ultrasonic for 10 minutes, take it out, dry it at 80°C, and set it aside;

[0035] (2) Preparation of flame retardant finishing solution: add 0.05mol of the compound of formula I, 0.01mol of crosslinking agent N-methylolacrylamide, and 0.01mol of dispersant sodium lauryl sulfate into 100ml of ethanol, at 80°C Stirring and reacting for 1 hour to obtain a flame retardant finishing liquid;

[0036] (3) Flame-retardant finishing: soak the cotton fabric in the above-mentioned flame-retardant finishing solution for 20 minutes, then double-dip and double-roll, and the excess rate is 85%. Bake for 2 minutes;

[0037] (4) Dry after alkali washing and water washing.

Embodiment 2

[0039] (1) Pretreatment of textiles: soak the cotton fabric to be treated in clear water, ultrasonicate for 30 minutes, take it out, dry it at 80°C, and set it aside;

[0040] (2) Preparation of flame retardant finishing solution: add 0.1mol of the compound of formula I, 0.03mol of crosslinking agent N-methylolacrylamide, and 0.02mol of dispersant sodium lauryl sulfate into 200ml of acetone, at 80°C Stirring and reacting for 2 hours to obtain a flame retardant finishing solution;

[0041] (3) Flame-retardant finishing: soak the cotton fabric in the above-mentioned flame-retardant finishing solution for 20 minutes, then dip and roll twice, the excess rate is 95%, then dry the textile at 90°C for 10 minutes, and then bake it at 180°C 8 minutes;

[0042] (4) Dry after alkali washing and water washing.

Embodiment 3

Abstract

The invention relates to a production process for flame-retarding textile. The production process is characterized by comprising the steps of textile padding sorting, drying, baking, alkali cleaning, water washing, stoving and the like. The textile processed through the production process is good in flame-retarding property and has higher limit oxygen index.

Description

technical field [0001] The invention relates to a textile production process, in particular to a production process of flame-retardant textiles. Background technique [0002] Flame retardants are a class of additives that prevent polymeric materials from igniting or inhibit the spread of flame. At present, there are many flame retardants for cellulose produced or researched at home and abroad, some of which are flame retardants containing phosphorus and halogens, such as tetramethylol developed by the British Albright-Wilson (Albright&Wilson) company in 1955 Phosphorous chloride (THPC), this flame retardant has a good flame retardant effect on cellulose, but it will release formaldehyde during use, and the halogen-containing flame retardant will produce toxic gas during thermal decomposition; Halogen, flame retardants containing phosphorus and nitrogen, such as N-dimethylolphosphonoacrylamide (NMDPPA, or PyrovatexCP) developed by Ciba Specialty Chemicals Co., Ltd., domestic...
