Preparation method of anti-cutting flame-retardant three-dimensional fabric

Abstract

The invention discloses a preparation method of an anti-cutting flame-retardant three-dimensional fabric. The preparation method comprises the following steps: step 1, compounding filament yarn cores(UHMWPE) and coated short fiber rough yarn to form anti-cutting flame-retardant yarn, the filament yarn core being made of an ultrahigh molecular weight polyethylene material, and the short fiber rough yarn being made of a Nomex material; and step 2, preparing modified warp yarn and weft yarn: performing sizing treatment on the anti-cutting flame-retardant yarn, a sizing agent being mixed size formed by boiling polyvinyl alcohol and starch with water, and the mass ratio of polyvinyl alcohol to starch being 1-2, airing for 4 hours at room temperature after sizing to obtain the modified warp yarn and weft yarn. Warps and wefts in the fabric provided by the invention are formed by compounding the filament yarn cores (UHMWPE) and the coated short fiber rough yarn (Nomex). The covering yarn hashigh strength of the filament (rigid yarn), and is wrapped with the short fiber yarn, so that the covering yarn has the flame-retardant property of Nomex, and meanwhile, maintains the high strength of UHMWPE, and thus excellent protection benefits are provided for the flame-retardant and anti-cutting fabric.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a preparation method of a cut-resistant and flame-retardant three-dimensional fabric. Background technique [0002] Developed countries such as the United States, Japan and Europe have earlier researched and developed protective clothing fabrics, and thermal protective clothing has been widely used in many industries. At present, a series of advanced and complete protective clothing fabrics, thermal protective clothing product standards and test method standards have been formulated and implemented, which can systematically design, develop and produce various types of thermal protective clothing, and better test and evaluate thermal protective clothing The new type of protective clothing for firefighters is composed of a flame-retardant layer, a waterproof and breathable layer, a heat-insulating layer and a comfortable layer. However, the flame-retardant effect of the existing fl...

At present, a series of advanced and complete protective clothing fabrics, thermal protective clothing product standards and test method standards have been formulated and implemented, which can systematically design, develop and produce various types of thermal protective clothing, and better test and evaluate thermal protective clothing The new type of protective clothing for firefighters is composed of a flame-retardant layer, a waterproof and breathable layer, a heat-insulating layer and a comfortable layer. However, the flame-retardant effect of the existing flame-retardant layer is not good, and the limiting oxygen index is low, and In the high temperature state, it is easy to produce molten droplets, which will cause damage to the body surface
