UHMWPE fiber is currently one of the strongest synthetic fibers in industrial applications. In addition to high strength and high modulus, UHMWPE fiber also has the advantages of low density, impact resistance, and cutting resistance, with a density of only 0.97 g/cm3, which is lower than most synthetic fibers. At the same time, its chemical stability, light resistance, and low temperature resistance are all excellent, making it widely used, such as in safety protection, navigation, and other fields In the fields of fisheries, sports equipment, and other related fields, products include bulletproof UD fabrics, anti piercing clothing fabrics, anti cutting gloves, various ropes, fishing nets, etc. However, these products are mostly long filament products. In comparison, UHMWPE short fibers and yarns have fewer products and applications, which are mainly related to market demand, costs, and other factors. However, from a usage perspective, short fibers and yarn products also have their advantages, such as higher degrees of freedom, It can be uniformly dispersed in various matrices, suitable for making composite material reinforced skeletons; Its yarn products are not easily hooked and have characteristics such as softness and good tactile sensation.
UHMWPE short fibers have a wide range of applications, in addition to being used for spinning high-strength yarns, they can also be used in building reinforcement materials, composite material skeletons, and so on. The research results of Ningbo Dacheng show that adding UHMWPE short fibers with a length of 19 mm to concrete can significantly improve its strength index. The mixing amount ranges from 0.1% to 0.5%, and the strength index shows an upward trend. When the mixing amount is 0.5%, the cube compressive strength and axial compressive strength increase by about 15%, the flexural strength increase by nearly 30%, and the splitting tensile strength increase by 78.9%. The strengthening effect is very obvious.
UHMWPE yarn can be used in various anti cutting and wear-resistant fabric products, such as protective gloves. Compared with long fibers, short fiber yarn fabric products have a soft hand feel, are not easy to hook, have the same wear resistance and anti cutting level, are sturdy, durable, and have good protective performance. They have a very broad application prospect in fields such as construction and rescue.
