Method for manufacturing flame retardant viscose fabric

Abstract

The invention discloses a method for manufacturing flame retardant viscose fabric, comprising the steps of: mixing and stirring pentaerythritol and phosphoric acid, reacting at 100-120 DEG C for 2-3 hours, further adding melamine into the mixture, and placing in an oven with a temperature of 190-200 DEG C for curing to obtain an intumescent flame retardant; and spraying the solid intumescent flame retardant on viscose fabric by using a vacuum magnetron sputtering device, keeping the spraying for 20 - 30 minutes, and low-temperature drying the viscose fabric to obtain the flame retardant viscose fabric. Via the manner described above, the present invention provides the method for manufacturing the flame retardant viscose fiber fabric which has self-extinguishing effect, and a good feel and comfort when the flame retardant viscose fiber fabric is dressed in the human body; continuous washing by water or long-time sun light have no influence on the flame retardancy of the flame retardant silk fabric; thus fundamentally preventing fire threat of textiles, and providing safety guarantee to people's lives and properties.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for making a flame-retardant viscose fabric. Background technique [0002] With the rapid development of science and technology and the continuous progress of the textile industry, the number and types of textiles are increasing, and their quantity and application range are also increasing significantly. They are applied to people's daily life to transportation, industry, military and other fields. There are more and more fires caused by textiles. At the same time, textiles produce toxic gases when they are burned, which has caused huge losses to people's lives and property, which has attracted people's attention. Traditional flame-retardant fabrics will produce toxic gases and violent smoke when they are burned. The flame-retardant time is short, which increases the difficulty for people to escape. The heat released during combustion is large, which causes huge losses in ...
