Example Embodiment

[0033] Example 1:

[0034] (1) Pretreatment of textiles: soak the cotton fabric to be treated in clean water, ultrasound for 10 minutes, take it out, and dry it at 80°C for use;

[0035] (2) Preparation of flame-retardant finishing solution: add 0.05 mol of formula I compound, 0.01 mol of cross-linking agent N-methylol acrylamide, and 0.01 mol of dispersant sodium lauryl sulfate into 100 ml of ethanol, at 80°C Stir and react for 1 hour to obtain flame retardant finishing solution;

[0036] (3) Flame-retardant finishing: immerse the cotton fabric in the above-mentioned flame-retardant finishing solution for 20 minutes and then double-dip and double-roll with a crease rate of 85%. Then dry the cotton fabric at 80°C for 10 minutes, and then at 150°C Bake for 2 minutes;

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

Example Embodiment

[0038] Example 2:

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

[0040] (2) Preparation of flame retardant finishing solution: add 0.1 mol of formula I compound, 0.03 mol of cross-linking agent N-methylol acrylamide, and 0.02 mol of dispersing agent sodium lauryl sulfate into 200 ml of acetone at 80°C Stir and react for 2h to obtain flame retardant finishing solution;

[0041] (3) Flame-retardant finishing: immerse the cotton fabric in the above-mentioned flame-retardant finishing solution for 20 minutes, then double-dip and double-roll, with a crease rate of 95%, then dry the textile at 90°C for 10 minutes, and then bake at 180°C 8 minutes;

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

Example Embodiment

[0043] Example 3:

[0044] (1) Pretreatment of textiles: soak the cotton fabric to be treated in clean water, ultrasound for 20 minutes, take it out, and dry it at 70°C for use;

[0045] (2) Preparation of flame retardant finishing solution: add 0.08 mol of formula I compound, 0.03 mol of crosslinking agent N-methylol acrylamide, and 0.02 mol of dispersant sodium lauryl sulfate into 200 ml of organic solvent at 80°C Stir and react for 2 hours to obtain a flame retardant finishing solution;

[0046] (3) Flame-retardant finishing: immerse the cotton fabric in the above-mentioned flame-retardant finishing solution for 20 minutes, then double-dip and double-roll, with a crease rate of 90%, then dry the textile at 90°C for 10 minutes, and then bake at 180°C 6 minutes;

[0047] (4) Dry after alkaline washing and water washing.

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...
