Twill weave

The continuous warp (weft) tissue dots on adjacent warp (weft) yarns are arranged in a diagonal line, and the fabric surface presents a continuous diagonally woven fabric structure. The twill weave has at least 3 yarns per tissue cycle. Woven twill fabrics are more complex than plain weaves, requiring at least a three-page heald frame. The emergence of twill fabrics marks a significant development in weaving technology and fabric construction. China has a twill pattern fabric in the Yin Shang era. The enamel and enamel in the silk fabric are woven with twill and its varying structure. Twill weaves are widely used, such as khaki, enamel, gabardine in cotton and wool fabrics, and beautiful silk in silk fabrics. The twill weave has a larger warp length than the plain weave, so the fabric structure is softer under the same yarn number (count) and warp and weft density. A larger warp density can be obtained to obtain a tightly structured fabric. The twill weave has three types of warp twill, which are mostly composed of tissue points, and the weft twill, which has the same number of weft and twill weaves. The oblique direction of the twill has a right oblique and a left oblique. Generally, the twill weave is represented by a fractional arrow with an oblique arrow. The oblique orientation of the twill weave is primarily selected based on the orientation of the yarn forming the diagonal weave on the surface of the fabric. If the slanting direction is opposite to the weave, the slanting line is clearer, and the slanting line is blurred. Therefore, when using "Z" 拈 single yarn as warp and weft, when using warp twill weave, we should choose left oblique; when weft weft is used, we should choose right oblique.

On the basis of the twill weave, the warp and weft tissue points are added respectively, and the weave diagonal direction, the flying number or the two methods can be used to evolve a variety of twill changes. 1Strengthen twill: Adding warp and weft tissue points on the basis of twill weave. The most common application is □ double-sided strengthening twill; 2 composite twill: generally twill weave with large number of tissue cycles, a set of fabric surface Different width and width of twill; 3 angle twill: changing the value of the flying number can change the inclination angle of the textured diagonal. Commonly used is a tissue with an inclination of more than 45°, with a large density, so that the slash is full and steep. The combed wool fabrics such as chocolate, tribute and so on are angled twill; 4 mountain-shaped twill: the structure of the mountain-shaped weave by the oblique lines in the left and right directions; 5 broken twill: the diagonal line from the left and right directions is fixed A tissue that is arranged to cause a sudden interruption of the textured slash. In addition, there are shadow twill, diamond twill, curve twill, etc., most of which are named after textured images. Twill-changing tissue is one of the main tissues used to increase the texture of the texture.
