About the introduction of aramid fiber

The aramid twisted silk ribbon is divided into a woven side belt (light side belt) and a non-woven side belt (burr belt). The main weave is plain weave. It is used to manufacture high-strength, dielectric-good electrical equipment parts and automotive hoses.

Aramid fiber twisted gauze mainly refers to various fabrics woven with aramid 1313 or a small amount of 1414 staple fiber yarn. Mainly used in fire retardant and other fields. The properties of the 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 warp and weft density plus the yarn structure determines the physical properties of the fabric, such as weight, thickness and breaking strength. There are five basic textures: plain, twill, satin, rib and mat.

The core fabric is a fabric composed of two parallel fabrics joined by longitudinal vertical strips, and the cross-sectional shape may be triangular or rectangular.

Sewing woven fabrics, also known as knit felts or woven felts, differ from ordinary fabrics as well as felts of the usual sense. A typical stitchbonded fabric is a layer of warp yarns that are overlapped with a layer of weft yarns, and the warp yarns and the weft yarns are woven together into a fabric by stitching.

Aramid cord fabric, which is a twisted aramid unidirectional fabric dipped, is characterized by high strength in the warp yarn at 0 degrees or 90 degrees in the weft yarn. The warp unidirectional fabric is a four-striped or long-satin satin fabric woven from coarse warp yarns and fine weft yarns for aircraft tires and automobile tires.

The three-dimensional fabric three-dimensional fabric is a relatively flat fabric, and its structural features are developed from one-dimensional two-dimensional to three-dimensional, so that the composite material with the reinforcement has good integrity and profiling, and the layer of the composite is greatly improved. Inter-shear strength and damage tolerance. It has been developed with the special needs of aerospace, aviation, weapons, ships and other departments, and its application has been extended to the automotive, sports equipment, medical equipment and other departments. There are five main categories: woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non-orthogonal nonwoven three-dimensional fabrics, three-dimensional woven fabrics, and other forms of three-dimensional fabrics. The shape of the three-dimensional fabric has a block shape, a column shape, a tubular shape, a hollow truncated cone, and a variable thickness profiled section.

The shape of the profiled fabric is very similar to the shape of the article it is to be reinforced and must be woven on a special loom. Shaped fabrics of symmetrical shape are: round caps, cones, caps, dumbbell-shaped fabrics, etc., and can also be made into asymmetrical shapes such as boxes and hulls.
