Description

Flame-retardant antistatic anti-cutting anti-stab fabric and production method thereof
Technical Field
The invention belongs to the field of production of textiles for safety protection, and relates to a flame-retardant antistatic anti-cutting anti-puncture fabric and a production method thereof.
Background
With the progress of the times and the continuous development and change of the international and domestic safety situation, the application range of the protective material is wider and wider, such as the fields of vehicles, body armor, explosion-proof helmets, sports equipment, stab-resistant clothes and the like. The development process of the protective material is from the initial adoption of a full hard material to a semi-hard material to a soft material. Early protective garments were either high performance alloy cold rolled to make an integrally formed stab resistant vest or high strength lightweight (e.g., aluminum alloy) metal materials to make a protective layer similar to a squama manicure, although the protective properties of this design were excellent, the quality and rigidity of the protective garment had a significant limitation and impact on the user's mobility and wearing comfort. In order to reduce the quality of protective clothing and improve the comfort of products, metal wires are twisted and woven or wound into metal rings, the end points are spot-welded, interlocked, and one or more layers are compounded with fabrics or other protective materials, or metal light sheets are made into spliced layers with certain shapes to enhance the protective effect of the materials.
In recent years, scholars at home and abroad apply high-performance fiber fabrics to the preparation of stab-resistant and cut-resistant products, and the purpose of soft material protection is achieved by adopting different high-performance fibers and fabric structures. The stab-resistant and cut-resistant fabric has important application in the field of safety protection, and a user can effectively resist external attacks while wearing the stab-resistant clothing made of the stab-resistant and cut-resistant fabric, so that the safety of the person and property is guaranteed.
The ultra-high molecular weight polyethylene (UHMWPE) fiber is combined with carbon fiber and para-aramid fiber to form three high-performance fibers. Due to the multiple excellent properties of ultra-light weight, high specific strength, high specific modulus, excellent energy absorption, better wear resistance, corrosion resistance, ultraviolet resistance and the like, the UHMWPE fiber has been widely applied in the fields of aerospace, national defense and military, safety protection, sports equipment, electric power communication, medical materials, industrial cables, marine cables, ocean fishing trawls, deep sea culture net cages and the like.
The cutting-proof and stab-resistant fabric and the high-grade cutting-proof gloves made of the UHMWPE short fibers have important application in the field of safety protection, and users can effectively resist external attacks and avoid the injury of sharp objects to hands when operating personnel are engaged in processing of machinery, automobiles, glass, food and the like while wearing the cutting-proof and stab-resistant clothes made of the cutting-proof and stab-resistant fabric. The existing method for preparing the UHMWPE short fiber anti-cutting and anti-puncturing fabric is to directly cut UHMWPE long fibers into short fibers, and then the short fibers are subjected to opening → carding → lapping → needling → sizing → hot press molding.
However, when the cut-resistant and stab-resistant clothes made of the UHMWPE short fibers are provided for high-risk task personnel such as firefighters and special armed polices, due to the fact that the ignition point of the UHMWPE short fibers is low, when the firefighters and armed polices are in the fire scene to rescue people or frontier defense and armed polices face to forest fire, the fabric is easily ignited by flame in the scene to cause injury to the firefighters and armed polices, and therefore the flame-retardant, antistatic, cut-resistant and stab-resistant fabric needs to be designed, the blank of products in the market can be filled, and the cut-resistant and stab-resistant clothes can be widely applied to manufacturing special protective clothes for personnel in industries such as chemical engineering, mines, coal mines, fire.
