Embodiment 1

[0014] A fabric for flame-retardant polyester protective clothing, comprising preparation of flame-retardant polyester fiber, preparation of base fabric, soft finishing, and drying treatment. The specific operation steps are:

[0015] 1) Preparation of flame-retardant polyester fiber: Melt blending and granulation of ethylene terephthalate and polyphenylene sulfide with a twin-screw extruder, the amount of polyphenylene sulfide added is ethylene terephthalate 8% by weight, prepared flame-retardant polyester chips, pre-crystallized by vacuum drying at 80°C for 12 hours, and then crystallized at 115°C for 24 hours, then melt-spun, cooled by ring blowing, oiled, and drawn for the first time. In the second drawing, the flame-retardant polyester fiber is formed by winding. The cooling temperature of the ring air is 70°C, the first drawing temperature is 170°C, the draw ratio is 1.8 times, and the second drawing temperature is 140°C. The expansion ratio is 3.0 times. Polyphenylene s...

Embodiment 2

[0020] A fabric for flame-retardant polyester protective clothing, comprising preparation of flame-retardant polyester fiber, preparation of base fabric, soft finishing, and drying treatment. The specific operation steps are:

[0021] 1) Preparation of flame-retardant polyester fiber: Melt blending and granulation of ethylene terephthalate and polyphenylene sulfide with a twin-screw extruder, the amount of polyphenylene sulfide added is ethylene terephthalate 8% by weight, prepared flame-retardant polyester chips, pre-crystallized by vacuum drying at 80°C for 13h, and then crystallized at 115°C for 24h, then melt-spun, cooled by ring blowing, oiled, and drawn for the first time.

Abstract

The invention discloses flame-retardant protective clothing polyester fabric. The flame-retardant protective clothing polyester fabric is prepared by cabling and twisting flame-retardant polyester fiber modified by polyphenylene sulfide with aramid fiber, basalt fiber and polyphenylene sulfide fiber, weaving, then finishing by using a softening agent, and drying. The flame-retardant protective clothing polyester fabric has the beneficial effects as follows: the flame-retardant protective clothing polyester fabric has excellent flame retardance, the advantages of various fibers complement one another to improve the flame retardance and the melt dripping resistance of a blended product, and during combustion, the flame-retardant protective clothing polyester fabric does not shrink and produce melt drips, so that the flame-retardant protective clothing polyester fabric is blended base fabric with relatively high cost performance; chemical substances harmful to a human body are not added, the preparation process causes a small environment impact and does no harm to the human body, and the flame-retardant protective clothing polyester fabric is high in softness and smooth in hand feel; the flame-retardant protective clothing polyester fabric is stable and long-lasting in flame retardance, an effective way of increasing product diversity is provided, an important method for improving product performance and expanding the application range is provided, and the commercial value is very high.

Description

technical field [0001] The invention relates to the technical field of clothing processing, in particular to a flame-retardant polyester protective clothing fabric. Background technique [0002] Many fires are caused by textiles, because most of the textiles we use in our daily life are flammable or combustible. Fibers are heated and decomposed under high temperature conditions to produce flammable gases, which then chemically react with oxygen. Continue to release heat, and the heat generated will promote the cycle of this process until the fibers are completely decomposed. In this way, if the fire fighting is not timely, it will cause the fire to spread. Certain fire-fighting measures can still be taken for small-scale fire spread. In a fierce situation, people may not be able to leave the fire scene in time, which will inevitably bring great losses to people's personal and property safety, which shows the importance of flame-retardant textiles to our lives. Flame-retarda...
