Problems solved by technology

[0002] Cotton fabric is widely welcomed and accepted by people because of its excellent physical and mechanical properties, good hygroscopicity, comfortable wearing, and wide range of sources. However, cotton fiber is a flammable fiber, and β-D- Glucose molecules are connected by β-1,4-glycosidic bonds to form a straight-chain macromolecule that melts when heated, and burns rapidly when exposed to fire, which can easily lead to fire accidents

Embodiment 1

[0024] The dosage of aminomethylphosphonate (DAMP) is 150g / L, the dosage of GPTMS is 40g / L, and the pH value of the finishing solution is adjusted to 4.0 with acetic acid to prepare the flame retardant finishing solution. Soak the cotton fabric in the above-mentioned finishing liquid, soak for 20 minutes at 40°C, dipping and rolling, and the liquid retention rate is 75%. Then dry at 100°C for 3 minutes, and bake at 165°C for 3 minutes, and the flame-retardant cotton fabric can be prepared. According to the prescribed flame-retardant test standards, the flame-retardant performance: after-flame time 0s, smoldering time 0s, damaged charcoal length 11.5 cm.

Embodiment 2

[0026] The dosage of aminomethylphosphonate (DAMP) is 300g / L, the dosage of GPTMS is 40g / L, and the pH value of the finishing solution is adjusted to 4.0 with acetic acid to prepare the flame retardant finishing solution. Soak the cotton fabric in the above-mentioned finishing liquid, soak for 20 minutes at 40°C, dipping and rolling, and the liquid retention rate is 75%. Then dry at 100°C for 3 minutes, bake at 165°C for 3 minutes, and the flame-retardant cotton fabric can be prepared. According to the prescribed flame-retardant test standards, the flame-retardant performance: after-flame time 0s, smoldering time 0s, damaged charcoal length 9.2 cm.

Embodiment 3

[0028] The dosage of aminomethylphosphonate (DAMP) is 300g / L, the dosage of GPTMS is 10g / L, and the pH value of the finishing solution is adjusted to 4.0 with acetic acid to prepare the flame retardant finishing solution. Soak the cotton fabric in the above-mentioned finishing liquid, soak for 20 minutes at 40°C, dipping and rolling, and the liquid retention rate is 75%. Then dry at 100°C for 3 minutes, bake at 165°C for 3 minutes, and the flame-retardant cotton fabric can be prepared. According to the prescribed flame-retardant test standards, the flame-retardant performance: after-flame time 0s, smoldering time 0s, damaged charcoal length 9.6 cm; after 10 times of washing, the flame retardant performance: the afterburning time is 0s, the smoldering time is 0s, and the length of damaged charcoal is 15.4cm.

Abstract

The invention relates to a method for preparing durable flame retardant cotton fabrics, which comprises the following steps: firstly, preparation of a finishing liquid, namely amino-methylphosphonate DAMP, a silane coupling agent gamma-glycidyl oxyl propyl trimethyl silicane and running water are uniformly mixed, and the pH value of the mixture is adjusted to between 3 and 7 by a finishing liquid pH regulator to obtain the finishing liquid; secondly, flame retardant finishing of the cotton fabrics, namely the cotton fabrics are immersed into the finishing liquid for 20 minutes at a temperature of 40 DEG C, padded until the liquid rate is between 75 and 80 percent, dried for 3 minutes at a temperature of between 80 and 100 DEG C, and roasted for 3 minutes at a temperature of between 150 and 180 DEG C; and thirdly, testing of the flame retardant property and the durability of the cotton fabrics after finishing. The method for preparing the flame retardant cotton fabrics has the advantages that raw materials have wide sources; the prepared cotton fabrics have good durability and flame retardant property; and the method has small influence on physical and mechanical properties of the cotton fabrics.

Description

technical field [0001] The invention belongs to the field of preparation of durable flame-retardant cotton fabrics, in particular to a method for preparing durable flame-retardant cotton fabrics for silicon-containing cotton. Background technique [0002] Cotton fabric is widely welcomed and accepted by people because of its excellent physical and mechanical properties, good hygroscopicity, comfortable wearing, and wide range of sources. However, cotton fiber is a flammable fiber, and β-D- Glucose molecules are connected by β-1,4-glycosidic bonds to form a straight-chain macromolecule that melts when heated, and burns rapidly when exposed to fire, which can easily lead to fire accidents. The potential flammability of cotton fiber has seriously affected the safety of people's lives and properties. Therefore, improving the flame retardancy of cotton fabrics plays an important role in reducing fire accidents. [0003] Among the durable flame retardant finishing agents for cott...
