Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the current flame retardant, conductive and dyeing of cotton fabrics generally need to dye the cotton fabric first, and then perform flame retardant or conductive finishing. Not only the process time is long, the cost is high, and the efficiency is low, but also the flame retardant and The conductive finishing process will affect the color shade of the dyed cotton fabric itself. It provides a one-step processing aid for the durable flame retardant, conductive and dyeing of cotton fabrics, and realizes the durable flame retardant, conductive and dyeing of cotton fabrics. In particular, it can realize Excellent flame retardant effect, durable flame retardant and conductive finishing, excellent color fastness

Abstract

The invention discloses a durable flame resistance, electric conduction and ash black dyeing one-step processing method of cotton fabric. According to the method, a flame retardant tetrakis hydroxymethyl phosphonium chloride (THPC) or tetrakis hydroxymethyl phosphonium hydroxide (THPOH) is reacted with graphene oxide (GO), and the hydroxymethyl of the flame retardant is reacted with the hydroxyl or epoxy group of the GO, so that a multifunctional finishing agent with flame resistance, electric conduction and dyeing functions is formed. The multifunctional finishing agent, urea, magnesium chloride and hexamethylolmelamine are prepared into a finishing liquor, the cotton fabric is subjected to padding of the finishing liquor, and the multifunctional finishing agent is subjected to drying andammonia finishing and is firmly fixed on the cotton fabric, so that the durable flame resistance, electric conduction and ash black dyeing cotton fabric is obtained. Flame resistance, electric conduction and ash black dyeing one-step processing method of the cotton fabric is realized through the method, the time is saved, the production efficiency is improved, and the multifunctional finishing agent is tightly combined with the cotton fabric, and the wash resistance is excellent.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, and in particular relates to a one-step processing method for durable flame-retardant, conductive and gray-black dyeing of cotton fabrics. Background technique [0002] Cotton fabric is one of the most commonly used textile fabrics at present. It has excellent hygroscopicity and soft feel. It is the first choice for shirts, underwear, tooling and other clothing fabrics. Cotton fabrics as special fabrics generally need to be dyed after dyeing. Flame retardant finishing, if the cotton fabric has a conductive effect, its antistatic ability can be greatly improved as a special fabric, but the flame retardant, conductive and dyeing of cotton fabrics generally need to be carried out step by step, looking for a cotton fabric flame retardant, conductive and dyeing One-step processing method is the pursuit goal of dyeing and finishing scientific and technological workers.
