What are the basic properties of textile fabrics

The basic properties of the fabric are mainly the fabric breaking strength (including the tensile breaking strength, tear strength and top tear strength of the fabric, etc.) and abrasion resistance, etc.

Tensile breaking strength reflects the solidity of the fabric when it is stretched by external force. Indicators include breaking strength, elongation at break, breaking work, breaking ratio work, etc. The breaking strength indicates the load on the unit cross-sectional area when the fabric breaks. Elongation at break indicates the elongation percentage of the fabric when it breaks in tension. The change of load and elongation of the fabric in the whole process of force is plotted as a coordinate graph, which can be used to calculate the work of breaking of the fabric. The elongation at break curve is related to the weaving shrinkage of the warp and weft yarns in the fabric, the greater the weaving shrinkage, the greater the elongation at the beginning of the stretching stage. The work of breaking is the work done by the external force when the fabric is stretched to break. The greater the work of breaking, the firmer the fabric.

        The fabric tear strength and yarn strength is roughly proportional. The organization is loose fabric, the number of yarns under stress increases, the tear strength of the fabric also increases.

The abrasion resistance of the fabric is the resistance of the fabric to wear and tear. The so-called wear refers to the fabric in the process of use often by another object to it repeatedly friction and gradually damaged. There are many types of wear and tear, mainly: ① flat grinding: is the fabric is subject to reciprocal or rotary plane friction, such as the sleeve of the clothes, pants, buttocks, socks, such as the bottom of the wear state; ② folded edge grinding: is the fabric folded edge of the wear, such as the collar, cuffs, trouser leg mouth and other folded edge of the wear state; ③ curved grinding: is the fabric in a bent state by repeated friction, such as the elbow of the sleeve of the clothes, trouser leg Knee wear state; In addition, there are a variety of factors by the wear of dynamic grinding, washing when the tumbling grinding, etc.. The abrasion resistance of the fabric can often reflect the fastness of the fabric.
