To be familiar with woven fabrics, these parameters to understand

Woven fabric

A fabric made from two systems of warp and weft spun yarns interlaced vertically with each other according to a definite pattern.

Warp yarn: The yarn arranged along the length direction (longitudinal) of the fabric.

Weft yarn: the yarn arranged along the width direction of the fabric (horizontal).

Fabric structure: warp and weft yarns in the fabric of the collection form.

Fabric structure is the fabric warp and weft yarn configuration of each other's structure. The study of fabric structure, in addition to the study of warp and weft yarns sink and stagger each other, and fabric organization, but also need to study their configuration in the fabric of the space form. Warp and weft yarns in the fabric of the spatial form is called the geometric structure of the fabric.

Decision fabric structure of warp and weft spinning yarn density, warp and weft alignment density, fabric organization of the three elements. These three elements are different, warp and weft yarn in the fabric of the spatial form is different. These three elements decision-making fabric tightness, fabric thickness and fabric weight, decision-making in the fabric warp and weft yarn flexure state, but also decision-making fabric surface form and pattern, thus deciding the performance and appearance of the fabric.

The relationship between density and tightness

The weft and warp density of the fabric is the absolute value of the tightness of the fabric, and warp and weft yarn thickness, can only compare the tightness of different fabrics with the same warp and weft yarn fineness. And tightness is a relative value of the degree of tightness of the fabric, and the fabric used by the thickness of the weft and warp yarn, regardless of the fabric adopted by the warp, weft yarn fineness, can be compared to the degree of tightness of the fabric, thick and thin.

The tightness of the fabric is a direct response to the fabric warp, weft density, in the fabric warp, weft density fineness is unchanged, the fabric warp, weft tightness and warp, weft density presents a linear relationship, with the warp, weft density increases, the fabric warp, for the tightness of the increase.

3 fabric length, width and thickness

Length

Length that is the length, to meter (m) as a unit of measurement. The size of the length according to the use of the fabric, thickness, weight and volume capacity to determine, all kinds of cotton fabric length of 25 ~ 40m; woolen fabric length, generally large for 60 ~ 70m, small for 30 ~ 40m.

Width

The width of the fabric refers to the large size of the fabric lateral, become effective width. The unit is centimeter (cm). The effective width of the fabric according to the use of the fabric, weaving finishing process of shrinkage Chengdu and finishing conditions to determine. The effective width of cotton fabric is divided into two categories: medium width is generally 81.5~106.5cm, and wide width is generally 127~167.5cm. The progress of new loom makes the width also change, and there are more and more wide fabrics.

Thickness

The vertical distance between the front and back sides of the fabric under definite pressure, measured in millimeters (mm). The fabric can be divided into three categories according to the thickness: thin, medium-thick and thick.
