Problems solved by technology

However, due to various reasons, many industries and environments that should use flame-retardant and heat-resistant textiles in my country are far from being fully used. The existing flame-retardant products in my country are far from meeting the needs in terms of output and quality. Product development has its social inevitability and urgency

Embodiment 1

[0011] Embodiment 1: A carbonization method of a viscose-based carbonized fireproof fabric, the viscose-based carbonized fireproof fabric adopts viscose fiber as a base material, and is obtained by cleaning, impregnating a flame retardant, and anaerobic carbonization; the viscose The fineness of the fiber is 4D, which is composed of 34% wood pulp, 62% cotton pulp and the balance of polyacrylonitrile. Carbonization method: Low-temperature heat treatment furnace starts at 160°C and heats up to 400°C at 8°C / MIN. After constant temperature for 20 minutes, it enters the cooling section. After cooling to less than 100°C, it is released from the furnace. The inlet and outlet and sides are sealed with nitrogen gas.

Embodiment 2

[0012] Embodiment 2: The fineness of the viscose fiber is 4D, which is composed of 35% wood pulp, 61% cotton pulp and the balance of polyacrylonitrile. All the other are with embodiment 1.

Abstract

The invention discloses a method for carbonization of a viscose-based carbonized fireproof fabric. Viscose fibers are taken as a base material and subjected to cleaning, impregnation in fire retardant and anaerobic carbonization to obtain the viscose-based carbonized fireproof fabric, and the viscose fibers are 4D in fineness and composed of, by weight, 33-35% of wood pulp, 60-64% of cotton pulp and the rest of polyacrylonitrile. The method for carbonization includes: heating the material in a low-temperature thermal treatment furnace from 160 DEG C to 400 DEG C by 8 DEG C / min, keeping the temperature for 20min, entering a cooling section, discharging from the furnace after the material is cooled to be lower than 100 DEG C, and subjecting an inlet, an outlet and lateral sides to nitrogen sealing. The viscose-based carbonized fireproof fabric has the advantages of fire retardation, high breathability, durability and wash resistance.

Description

technical field [0001] The invention relates to a carbonization method for a fireproof fabric, in particular to a carbonization method for a viscose-based carbonized fireproof fabric. Background technique [0002] Textiles are a necessity in people's daily life, and fires caused by textiles have been on the rise in recent years. According to statistics, more than 20% of fire accidents are caused by non-flammable textiles. Fire accidents caused by textiles igniting or spreading proportion is greater. Therefore, domestic and foreign attach great importance to the research of flame-retardant textiles. Many countries have made special legislation on textile products such as pajamas, bedding, hotels, and aviation decoration for the elderly and children, stipulating that flame-retardant products must be used; at the same time, with the development of society With the improvement of people's living standards and the improvement of the working environment, higher requirements are p...
