A kind of manufacture method of the anti-stab protective fabric containing silk
Technical field:
The invention belongs to field of textiles, be specifically related to a kind of preparation method of the anti-stab protective fabric containing silk.
Background technology:
In recent years along with the development of society and science and technology, people more and more focus on self safety, and comfortable Portable puncture-proof protective garment comes into daily life, and day by day by people are paid close attention to.Stab-resistant material when bearing the devices such as cutter stressed, need bear perpendicular to fabric face shearing force and be parallel to the tensile force of fabric face, so anti-stab protective garment needs to have anti-shearing and stretch-resistance, and anti-shear performance is occupied an leading position.
Silk is the natural fiber of function admirable, have the good reputation of " fiber queen ", it has good hot strength and percentage elongation, fiber delicate and high resilience, and by the silk gum on set silk surface, the mechanical performance of silk fiber can be significantly improved further.Superhigh molecular weight polyethylene fibers has the characteristic of low-density, high-tenacity, high-modulus, endurance and rub resistance, has very large application prospect in protection field.
Non-woven fabrics does not need weaving, and directly by the fabric that physical means bonding is formed, compared with woven fabric, its operating procedure is easy, and require low to fibrous material, cost ineffective rate is high, and its anti-shear performance is higher than stretch-proof performance.
Summary of the invention:
The object of this invention is to provide a kind of manufacture method of the anti-stab protective fabric containing silk, the method utilizes the performance of the excellence of silk can improve the wearability of anti-stab protective garment, and make fabric central core by Sericin Gumming and one deck superhigh molecular weight polyethylene fibers film, the cutting performance of non-woven fabrics can be significantly improved.
Object of the present invention is achieved through the following technical solutions:
Containing a preparation method for the anti-stab protective fabric of silk, comprise the following steps:
(1) the silk waste material shredding of 100% is become ultimate fibre shape, remove impurity, control the length of fiber at 3-6cm, and silk fiber is carded to sheet;
(2) one deck superhigh molecular weight polyethylene fibers film is positioned over a lamellar silk fiber surface, then the surface of film is spread a lamellar silk fiber;
(3) fibrage is statically placed in solid jelly steam, after making the silk gum glue set of silk, by vertical hot pressing, forms non-woven fabric.
Preferred as technique scheme, the silk described in step (1) is raw silk or half boiled-off silk, and content of silk gum is 15%-25%.
Preferred as technique scheme, the film thickness described in step (2) is 1mm.
Preferred as technique scheme, the solid jelly of step (3) described silk gum is glutaraldehyde, and pH value is 3-5, and time of repose is 1-2h.
Preferred as technique scheme, the described vertical hot pressing temperature of step (3) is 150-260 DEG C, and pressure is 90-120KPa.
Preferred as technique scheme, step (3) described fabric thickness is 3-8mm.
Beneficial effect of the present invention is: utilize the performance of the excellence of silk can improve the wearability of anti-stab protective garment, and makees fabric central core by Sericin Gumming and one deck superhigh molecular weight polyethylene fibers film, can significantly improve the cutting performance of non-woven fabrics.By regulating temperature and the pressure of hot pressing, controlling the structure of fabric, thickness and intensity, obtaining the anti-stab protective fabric of high strength.
