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.
