Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 . A manufacturing method (parts by mass) of a multi-functional outdoor protective fabric: (1) Select a phosphorus-based reactive permanent flame-retardant polyester with a P content greater than 8000PPM, pre-crystallize it in vacuum at 80-140°C, and dry it for 8-12 hours to reach the characteristic Viscosity ≥ 0.8dl / g, fine denier staple fiber 1 dtex X38mm, staple fiber strength ≥ 5.0CN / dtex; the staple fiber is spun into 21S spun yarn, and the warp and weft strands are used for weaving after plying; The weaving method is to weave gray cloth with a warp and weft density of 60X30; (3) finish the gray cloth after printing and dyeing, and the preparation of the finishing agent: 8-10% waterproof and oil repellent silicone fluororesin, 2-3% far-infrared nano Ceramic powder and an appropriate amount of cross-linking agent epichlorohydrin rubber (ECO) are made into an aqueous solution; (4) Post-treatment process: Put the print...

Abstract

The invention relates to a manufacturing method of a multifunctional outdoor protective fabric. Flame-retardant polyester with a high phosphorus content is selected and used as a raw material, and is subjected to vacuum drying and pre-crystallization for 8-12 hours until the intrinsic viscosity is greater than or equal to 0.8 dl / g, high-strength fine-denier short fibers are obtained and are spun to be yarn, and the yarn is stranded, is woven and is subjected to post-processing technologies comprising water proofness, oil repellence, infrared proofness, and the like, so as to enable the multifunctional outdoor protective fabric to have following advantages that firstly, the flame-retardant performance is good: the oxygen index is greater than or equal to 37 percent and the multifunctional outdoor protective fabric is environmentally friendly and is permanent flame-retardant; secondly, the water-proof performance is good: the hydrostatic pressure is greater than or equal to that of 60 cm water column; thirdly, the oil-repellent performance is good: the oil-repellent performance reaches a level of six; fourthly, the infrared-proof performance is good: the wavelength is in the range of 750 nm to 1500 nm, and the transmissivity is in the range of 5.1 percent to 6.6 percent; fifthly, the breaking strength is large: the warp breaking strength of a base cloth is greater than or equal to 2700 N, and the weft breaking strength of the base cloth is greater than or equal to 1800 N; sixthly, the gram weight is greater than or equal to 200g / m<2>, and the multifunctional outdoor protective fabric is convenient to use; and seventhly, the air permeability is good, the water vapor permeability is greater than or equal to 8000g / m<2>.24h, and the multifunctional outdoor protective fabric is comfortable to use.

Description

technical field [0001] The invention relates to a tarpaulin suitable for military and civilian tents, vehicles, equipment, etc., and has flame-retardant, waterproof, oil-repellent, infrared-proof, high breaking strength, light weight per unit area, convenient use and good air permeability. The invention discloses a method for manufacturing a comfortable and multifunctional outdoor protective fabric, belonging to the field of preparation of special fabrics. Background technique [0002] Publication number CN 102326903A, name: a multi-functional protective fabric, including a barrier layer and a comfort layer, the barrier layer is a ceramic aluminum oxide metal film layer, and the comfort layer is a natural fiber or artificial fiber that has undergone flame-retardant treatment The knitted fabric layer, the comfort layer is compounded with a composite layer with thermal insulation function and moisture permeability. Disadvantages: The function of the multi-layer composite fabr...
