Embodiment

[0034] In order to give full play to the respective performances of the two aramid fibers and make them exceed the functions of conventional fireproof materials, this plan separately considers the composite method of the two aramid fibers, optimizes the best matching ratio, and determines the appropriate organizational structure, tightness and specifications. and other key issues, and formulated a series of optimal production process routes from raw material selection to spinning, weaving, finishing, etc., and through the research of key technologies, the development of composite aramid aviation flame-retardant fabrics has been achieved. good effect.

[0035] 1. Technical solution

[0036] 1. Raw material properties

[0037] The full name of the raw material aramid used is "aromatic polyamide fiber" (English name Aramid fibers). Because the high polymer long chain molecules that make up the fiber contain amide groups, it belongs to the same type of polyamide fiber as nylon. ...

Abstract

The invention relates to composite aramid fiber aviation flame retardant fabric and a processing technology thereof. The fabric is formed by aramid fiber 1313 and aramid fiber 1414 fiber in a woven mode, wherein the percentage ratio, by weight, of the aramid fiber 1313 and aramid fiber 1414 fiber is 50 to 50. The fabric construction of the fabric is 2 / 2 right hand twill fabric. The process technology of the composite aramid fiber aviation flame retardant fabric solves the technical problems of fire retardant fiber in the process of spinning, weaving and after treatment. The composite aramid fiber aviation flame retardant fabric has the advantages that the blank space of aramid fiber aviation flame retardant fabric in the country is filled, the aramid fiber 1313 and aramid fiber 1414 composite aviation flame retardant fabric do not burn when meeting fire, do not drip melt and do not generate smoke and have good fireproof effects, and when the aramid fiber 1313 and aramid fiber 1414 composite aviation flame retardant fabric meet a high temperature of 900-1500 DEG C, the fabric surfaces are rapidly carbonized and thickened to form a special heat insulation barrier. The fabric has a permanent flame retardant effect, the flame retardant protecting effect is good and reaches a world standard, the price of the fabric is 20% of the price of a like product imported from a foreign country, and therefore the fabric has good market competitiveness.

Description

(1) Technical field [0001] The invention relates to a fabric in the textile field and its processing technology, in particular to a composite aramid aviation flame-retardant fabric and its processing technology. (2) Background technology [0002] Flame retardant is an eternal subject for human beings to conquer nature in order to reduce disasters. It is also an important measure to improve public fire protection capabilities in contemporary society and ensure that people's lives and properties are not devoured by fire. In today's world, synthetic fiber materials and natural fibers have become important materials for people's daily necessities, but the fire hazard caused by their flammability (the limiting oxygen index is mostly 17-20) has become a social issue of global industry concern. To this end, countries around the world have successively formulated a series of related flame retardant regulations, involving curtains, curtains, carpets, pads, bedspreads and fiber orname...
