Forming (Ⅱ) structure under acidic conditions: NH3-W-COOH (H +) ← → NH3 + -W-COOH (A-) ← → A- · NH3 + -W-COOH (Ⅱ) structure of the amino positive ions easily form (Ⅲ) structure with anion A- wool flame effect, its mode of action of acid dyes for wool dyeing identical, so make wool products with flame retardant properties. Because flame WA-S is completely colorless, and it reacts Weifang retardant wool and wool fiber protein molecule amino, so after finishing wool fabric feel no change, natural stain repellency unaffected retardant wool agent manufacturers, and fastness are not affected. Meanwhile retardant wool market prices, due to the WA-S and healthy combination of wool price occurred, compared with the early flame with high efficiency, low cost, durability and other characteristics. Shandong Antai New Material Technology Co., Ltd. Main retardant wool, welcome new and old customers to buy. My company provides products flame test analysis. Retardant finishing process optimization: flame retardant finishing process, take the process as follows: casual hair → dipping → dehydration → washing → dehydration → drying. In the optimization process, select the factors of pH, temperature, concentration, time of these four can significantly affect the flame retardant effect. Because flame effect can be measured by the length of the carbon fabric, limiting oxygen index values, than burning, smoldering time to represent, and the amount of adsorption of these values ??with the flame retardant fabric has a direct relationship, it can be measured by the fiber or to measure the rate of weight gain fabric flame retardant effect obtained. And this method is simple, reproducible, high accuracy, simply by weighing constant temperature can be measured. Shandong Antai New Material Technology Co., Ltd. Main retardant wool, welcome new and old customers to buy. My company provides products flame test analysis. Flame retardant finishing three ways: (1) exhaust combustion method: flame retardants and cellulose fibre ionic bond or covalent bond, it does not dissolve in fibre obtain durability fire-retardant effect. (2) dope method: the flame directly into the spinning solution. (3) copolymerization method: flame retardant added to the polymer chain segments, the fabric has a washable, resistant to bleaching, perspiration fastness and other qualified, not caused by skin absorption.
