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 with excellent flame retardant performance, the viscose fiber is used as the base material, obtained by cleaning, impregnating a flame retardant, and anaerobic carbonization; the viscose fiber The fineness is 3D, which is composed of 22% wood pulp, 54% cotton pulp and the balance of phenolic resin. 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 3D, and it is composed of 25% wood pulp, 53% cotton pulp and the balance of phenolic resin. All the other are with embodiment 1.

Abstract

The invention discloses a carbonization method for a viscose-based carbonized fireproofing fabric with excellent flame resistance. Viscose is adopted as a substrate, and is obtained through cleaning, fire retardant soaking, and anaerobic carbonizing treatment; the fineness of the viscose is 3D, and is composed of 20 to 25 percent of wood pulp, 50 to 55 percent of cotton pulp and the balance of phenolic resin; the carbonization method comprises the following steps: increasing the temperature of a low temperature heat treating furnace to be 400 DEG C from the temperature of 160 DEG C at the speed of 8 DEG C per min for 20 min, then entering into a cooling section, discharging after cooling to be a temperature lower than 100 DEG C, and sealing an inlet and side surfaces by using nitrogen. According to the carbonization method provided by the invention, the fire prevention, the flame retardance and the breathability are good, and durability and cleanabilitry are achieved.

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...
