Abstract

The invention discloses a mixed woven flame-retardant filter bag glass fiber which comprises, by weight, 2-4 parts of diethyl aluminum phosphinate, 50-60 parts of terephthalic acid, 70-80 parts of glycol, 1-2 parts of catalysts, 100-130 parts of amino glass fiber solution, 6-7 parts of methyl methacrylate, 8-10 parts of glycidol, 0.01-0.02 part of lithium methoxide and 1-2 parts of triethylamine.Epoxide ring-opening is promoted under the action of the triethylamine, the glass fiber is woven in a mixed manner, so that the composite strength of the glass fiber and a polyester fiber is improved,and the mechanical stability and toughness of a finished fiber material are enhanced.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a mixed woven flame-retardant filter bag glass fiber and a preparation method thereof. Background technique [0002] Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Due to its permanent flame retardancy, flame-retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, architectural interior decoration, and vehicle interior decoration, it also plays a lot of roles in the field of protective clothing. According to the national standards for flame-retardant protective clothing, metallurgy, forestry, chemical, petroleum, fire-fighting and other departments should use flame-retardant protective clothing. The number of people who should use flame-retardant protective clothing in China is more than one million, and the market potential of flame-retardant protec...
