What material is aramid cloth? The function of aramid cloth, also known as Kevlar cloth, aramid fiber cloth, aramid fabric. Aramid Fiber Cloth or Fabric/Kevlar Fabric There are mainly the following types 1. Aramid fiber untwisted roving fabric is mainly made of Aramid 1414 filament, which is composed of parallel primary fibers or parallel single fibers bundled together. The single filament diameter of aramid fibers used in the production of roving ranges from 5 to 15 μ M is not equal. The count of untwisted coarse yarn ranges from 100 to 8000 (tex). Untwisted coarse yarn can be directly used in certain composite material processing methods, such as special textiles, sheet pre impregnation, pipeline winding, profile extrusion, etc. Untwisted yarn can be woven into untwisted coarse yarn fabric and special aramid fabric due to its uniform tension, which is used in special industries such as aerospace, national defense, and military industry. There are mainly low weight aramid plain weave fabrics and one of the bulletproof fabrics; Aramid weft free fabric, also known as UD bulletproof fabric; Aramid unidirectional fabric, used in situations where high strength is required in a single direction at 0 degrees longitude or 90 degrees latitude, such as structural repair, seismic reinforcement, building reinforcement, bridge reinforcement, etc; Decorative aramid fabric can also be woven into twill aramid fabric and colored aramid fabric. 2. Aramid non-woven fabric, felt sheet, aramid paper, used for insulation and insulation 3. Aramid fiber twisted fine gauze, aramid fabric, aramid fabric, mainly using aramid 1313 or a small amount of 1414 short fibers (1) Aramid fiber twisted fine gauze mainly refers to various fabrics woven by twisting aramid 1313 or a small amount of 1414 short fiber yarn. Mainly used in fields such as fire prevention and flame retardancy. The characteristics of a fabric are determined by fiber properties, warp and weft density, yarn structure, and texture. The warp and weft density is determined by the yarn structure and texture. The combination of warp and weft and yarn structure determines the physical properties of a fabric, such as weight, thickness, and fracture strength. There are five basic weaving patterns: plain, twill, satin, ribbed, and mat. (2) Aramid twisted ribbons are divided into woven edge bands (smooth edge bands) and non-woven edge bands (rough edge bands). The main weaving method is plain weave. Used for manufacturing electrical equipment components with high strength and good dielectric properties, as well as automotive hoses. (3) Aramid curtain fabric, which is a twisted unidirectional aramid fabric impregnated with glue, is characterized by high strength in the 0 degree warp or 90 degree weft direction. The warp unidirectional fabric is a four warp broken satin or long axis satin fabric woven from coarse warp and fine weft yarns, used for aircraft tires and high-end automotive tires. (4) Compared to flat fabrics, three-dimensional fabrics have developed their structural characteristics from one-dimensional and two-dimensional to three-dimensional, which makes composite materials reinforced with them have good integrity and shape imitation, greatly improving the interlayer shear strength and damage resistance tolerance of composite materials. It has developed with the special needs of sectors such as aerospace, aviation, weapons, and ships. Currently, its applications have expanded to sectors such as automobiles, sports equipment, and medical equipment. There are mainly five types: machine woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non orthogonal non-woven three-dimensional fabrics, three-dimensional woven fabrics, and other forms of three-dimensional fabrics. The shapes of three-dimensional fabrics include block, column, tube, hollow truncated cone, and variable thickness irregular cross-section. (5) The shape of the irregular fabric is very similar to the shape of the product it is intended to enhance, and it must be woven on a dedicated loom. Asymmetric shaped fabrics include round covers, cones, caps, dumbbell shaped fabrics, and can also be made into asymmetric shapes such as boxes and ship shells. (6) Slot core fabric is a fabric composed of two parallel layers connected by longitudinal vertical bars, with a cross-sectional shape that can be triangular or rectangular. (7) Knitted fabrics, also known as knitted felt or woven felt, are different from ordinary fabrics and from the usual sense of felt. The most typical knitted fabric is a layer of warp and weft yarns that overlap and are woven together through sewing to form a fabric. 3. Combination aramid fabric The aramid composite fabric is composed of aramid felt, aramid untwisted coarse yarn fabric, and aramid untwisted coarse yarn in a certain order.

芳纶纤维是什么?芳纶纤维基本特性;芳纶纤维,其主要成分是对苯二胺聚合物(PPTA),其中既含脂肪族主链又含芳香族主链,所以有牢固的分子结构,芳纶纤维是由直径为12um左右的单丝汇集在一起形成的多纤维状结构,芳纶布是芳纶纤维由单向或双向排列形成的一种片材,常用的是单向片材。
