Problems solved by technology

However, the above-mentioned conventional thermal processing technology has some problems: natural fibers such as cotton are not easy to be processed into durable flame-retardant fibers; conventional reaction conditions are harsh, and high temperature of 160-190°C and long-term baking and heating are likely to cause serious loss of fiber strength or damage to the surface of the cloth sample. The yellowing is serious, and fiber protective agent needs to be added during the processing, which increases the cost of finishing and wastewater treatment; the equipment used in conventional processing technology is complicated to operate and cannot be terminated at any time; the processing technology is complicated, with many uncontrollable factors and side reactions, and the product Quality is not easy to control, etc.

Embodiment 1

[0032] Cotton fabric is padded with flame retardant finishing solution containing 450g / L durable flame retardant DM3070 (reactive organic phosphorus flame retardant), 100g / L crosslinking agent DM-3522 (resin crosslinking agent), and the remaining The efficiency is 100%. After taking it out, it is irradiated with 43KGy electron beams and dried at 100°C for 120s. After washing with water and drying, a flame-retardant pure cotton fabric is obtained.

Embodiment 2

[0039] Pad polyester fabric with flame retardant finishing solution containing 200g / L durable flame retardant DM3070 and 60g / L crosslinking agent DM-3522, take it out, irradiate it with 32KGy electron beam, and dry it at 100℃ for 120s. After washing with water and drying, a flame-retardant polyester fabric is obtained.

Embodiment 3

[0046] Flame retardant finishing of pure cotton fabric by padding containing 400g / L flame retardant DM3074 (composite flame retardant of phosphate ester and various flame retardant components) and 20g / L FM-2 crosslinking agent (resin crosslinking agent) After taking out the solution, it was irradiated with 23KGy electron beam and dried at 100°C for 120s. After washing with water and drying, a flame-retardant polyester fabric is obtained.

Abstract

A method of producing flame retardant textile by the electronic radiation technology is characterized in that after textile is pad-rolled or coated with flame retardant finishing liquid, and drying or baking is performed after electronic beam radiation to obtain the flame retardant textile; the flame retardant fishing liquid comprises resin cross-linking agent and organophosphorus flame retardant. The method has the advantages that the technical operation is simple and the flame retardant textile has performances such as durability, high temperature resistance and non-flammability.

Description

technical field [0001] The invention relates to the technical field of textile production and processing, in particular to the use of electron radiation technology to prepare flame-retardant textiles that are non-flammable, smoke-less, washable and wearable. Background technique [0002] Modern cities are densely populated, with more and more high-rise and underground buildings, and more and more fire hazards such as wires, radiation, and electrical appliances. Many fires are caused by the fire or spread of textiles, especially the proportion of residential fires. To reduce the occurrence of fires and reduce fire hazards, the development of flame-retardant products including flame-retardant textiles has been put on the agenda. Flame-retardant textiles are extremely important to eliminate fire hazards, delay the spread of fire, and reduce the loss of people's lives and property. After flame-retardant finishing, textiles can reduce the flammability to varying degrees, and can...
