Embodiment 1

[0055] (1), Padding:

[0056] First prepare the flame retardant finishing liquid, in which:

[0057] AFLAMMIT KWB Flame Retardant 480g / L

[0058] Phosphoric acid 22g / L

[0059] Cross-linking agent TMM 20g / L

[0060] A105 Penetrant 2g / L

[0061] Secondly, the cotton reactive printed knitted fabric is dipped in the flame-retardant finishing solution, one dip and one roll, the roll pressure is 0.22MPa, and the excess rate is 100%;

[0062] (2) Low-temperature drying: control the temperature at 100-120°C and control the speed at 9y / min for drying, subject to thorough drying;

[0063] (3) High-temperature baking: bake at 160°C for 2 minutes;

[0064](4) Water washing: wash with cold water first, then wash with alkali at 50°C for 10 minutes, then wash with water at 70°C for 10 minutes, then wash with 1.5mL / L 27.5% hydrogen peroxide at 40°C for 10 minutes, and finally wash with cold water;

[0065] (5), drying: drying the finished cloth;

Abstract

The invention discloses an environmentally-friendly and long-lasting fire-retarding treatment method for all-cotton knitted fabrics, which adopts a processing flow comprising padding, low-temperature drying, high-temperature drying, washing with water, drying and softening and deodorizing. In the invention, an Aflammit KWB fire retardant is used, processing is performed on the conventional dyeingand finishing equipment, and the products have higher fire-retarding performance due to the combination of the fire retardant and cotton fibers by covalent bonds and offer a soft handfeel and are more in accordance with an environment protection requirement. The products produced by the process offer a soft handfeel, the fire-retarding effect after 50 times of washing with water reaches American CFR1615 standards, the formaldehyde content is lower than 20ppm, the products are more environmentally-friendly and have no irritating smell.

Description

technical field [0001] The invention discloses a flame-retardant finishing method for knitted fabrics, in particular to an environmentally friendly and durable flame-retardant finishing method for all-cotton knitted fabrics. Background technique [0002] In recent years, the number of fires caused by textiles and the resulting economic losses are higher than those caused by other causes, and have become a major social problem. In order to prevent fires from happening, in addition to strengthening fire prevention measures, many countries also use flame retardant textiles. Flame-retardant textiles can prolong the time for people to evacuate and take measures to put out fires. Many countries such as the United States, Japan, and the European Union have successively issued a series of textile flammability technical regulations and market access systems. Flame-retardant textiles are widely used in clothing, decoration and industry. , the development of flame-retardant textiles i...
