What Material Is Aramid Fabric Made Of?

The function of aramid cloth, aramid cloth is Kevrab, aramid fiber cloth, aramid fabric. There are mainly the following types
1, aramid fiber no-twist roving fabric, mainly with aramid 1414 filament, no-twist roving is composed of parallel prefilament or parallel monofilament cluster. The diameter of the monofilament of the arlon fiber used in the production of roving varies from 5 to 15μm. Untwisted roving is available in numbers 100 to 8000 (tex). Non-twist roving can be directly used in some composite material process forming methods, such as special textile, sheet prepreg, pipe winding, profile pultrusion and other processes, non-twist yarn because of its uniform tension, can be woven into non-twist roving and special arnylon fabric, used in aerospace, national defense, military and other special industries.
Mainly low weight aramid plain fabric, one of the bulletproof fabric; Aramid weft less cloth, namely UD bulletproof cloth; Aryl fiber unidirectional fabric, used for requiring high strength in a single direction of 0 ° warp or 90 ° weft, such as structural repair, seismic reinforcement, building reinforcement, bridge reinforcement, etc.; Decorative aramid cloth can also be woven into twill aramid cloth and colored aramid cloth.
2, aramid non-woven fabric, felt sheet, aramid paper, for insulation and heat preservation
3, aramid fiber twist gauze, aramid fabric, aramid fabric, mainly with aramid 1313 or a small amount of 1414 staple fiber
(1) Aramid fiber twist gauze mainly refers to a variety of fabrics woven with aramid 1313 or a small amount of 1414 short fiber yarns after twisting. Mainly used in fire prevention and flame retardant fields. Fabric properties are determined by fiber properties, warp and weft density, yarn structure and weave. The warp and weft density is determined by the fabric structure and weave. The warp and weft density, together with the yarn structure, determines the physical properties of the fabric, such as weight, thickness and breaking strength. There are five basic weaves: plain, twill, satin, rib and matte.
(2) Aramid twisted webbing is divided into woven side strips (light edge strips) and non-woven side strips (raw edge strips). Used for manufacturing high-strength, good dielectric properties of electrical equipment parts and automotive hose.
(3) aramid cord fabric, that is, twisted aramid unidirectional fabric dipped by glue, which is characterized by high strength in the warp 0 degree or the weft 90 degree direction. Among them, the warp one-way fabric is a four-warp broken satin or long-axis satin fabric woven with coarse warp and fine weft, which is used for aircraft tires and advanced automobile tires.
(4) Three-dimensional fabric Three-dimensional fabric is relative to flat fabric, its structural characteristics have developed from one-dimensional two-dimensional to three-dimensional, so that the composite material as the reinforcement has good integrity and shape copying, greatly improving the interlayer shear strength and damage tolerance of the composite material. It is developed with the special needs of aerospace, aviation, weapons, ships and other departments, and its application has been expanded to automobiles, sports equipment, medical equipment and other departments. There are five main categories: woven 3D fabrics, knitted 3D fabrics, orthogonal and non-orthogonal non-woven 3D fabrics, 3D woven fabrics and other forms of 3D fabrics. The shape of three-dimensional fabric includes block, column, tube, hollow truncated cone and variable thickness shaped section.
(5) Special-shaped fabric The shape of the special-shaped fabric is very similar to the shape of the product it is intended to enhance, and must be woven on a special loom. Symmetrical shape of the special-shaped fabric are: cap, cone, cap, dumbbell fabric, etc., can also be made into boxes, hull and other asymmetric shapes.
(6) Slot core fabric is a fabric composed of two layers of parallel fabric, connected by vertical bars, and its cross-section shape can be triangular or rectangular.
(7) Stitched fabric is also known as knitted felt or woven felt, it is different from ordinary fabric, but also different from the usual sense of felt. The most typical stitched fabric is a layer of warp and a layer of weft overlapping, by sewing the warp and weft woven together into fabric.
4. Combined aramid fabric
That is, the aramid felt, aramid untwisted roving fabric and aramid untwisted roving fabric are combined in a certain order.
