Warp velvet is a fabric made up of two sets of warp yarns (ground warp and velvet warp) and one set of weft yarns interwoven into a double layered structure. After being cut into velvet, it becomes two single layers of flat velvet with flat nap. The texture of the flat velvet is generally plain weave, and the consolidation of the warp is mainly carried out using the V-shaped consolidation method. The arrangement ratio of the warp to the warp is 2:1 and 1:1. Jingping velvet is pided into train velvet and mercerized velvet according to the length of the pile. Train fluff is long and commonly used as a train seat cushion; Mercerized velvet has short down and is treated with mercerization, resulting in a shiny fabric surface. It is commonly used for clothing, military collars, and decorations

Product characteristics

1. The wear resistance is 4-5 times higher than that of ordinary fabrics.

. Because the surface of velveteen fabric is in contact with the outside world through fiber cross-section, it avoids friction at the bottom of the fabric 2. The velvet surface is densely covered with towering fluff, making it soft and elastic to the touch, with a soft luster, and the surface is not prone to wrinkling 3. The fabric body is thick and the surface fuzz can form an air layer, thus providing good warmth retention So velveteen fabrics are very popular among people and are commonly used in daily life and architectural decoration

Appearance

Excellent velveteen fabric products should meet the requirements of plump and upright fluff, even and dense fluff, smooth and smooth fluff surface, soft color, small directionality, soft and smooth hand feel, and full of elasticity.

Characteristic indicators

1. Pile cross-sectional coverage

Pile cross-sectional coverage is the sum of the pile cross-sectional area and the percentage of the total ground area.

. The high coverage of the pile cross-section indicates a good fullness of the pile surface

2. Pile height

Pile height refers to the average height of a single pile standing upright on the surface of a fabric after cutting.

. When the height of the pile is high, the pile surface is straight and has poor elasticity, but the pile surface is relatively plump

3. Fullness of pile surface

The fullness of pile surface refers to the volume of pile on a unit area of fabric.

. It includes two factors: the coverage rate of the villi and the height of the villi. The unit of fullness of suede is "density". The higher the 'density', the fuller the suede surface. The common velvet surface fullness of weft velvet is around 11 density, while that of warp velvet is around 15 density

4. Pile Consolidation Tightness

The pile consolidation tightness refers to the degree to which the pile yarn is compressed by the arrangement of ground warp yarns and pressed warp yarns in the fabric structure.

. The greater the consolidation tightness, the better the consolidation fastness of the fluff, and the less likely it is to depilate. The consolidation tightness of velvet is represented by the organizational tightness in the direction of the velvet and weft yarns, which is equal to the sum of the warp tightness of the fabric and the tightness of the interweaving points of the velvet and warp yarns. The degree of consolidation and tightness of velvet in the fabric structure indicates the degree to which the warp yarn is compressed by the arrangement of weft yarns

5. Uniformity of Pile Cover

Uniformity of Pile Cover is represented by the ratio of the longitudinal and latitudinal spacing of pile cover.

. It is an important indicator related to obtaining a good velvety style. The coverage uniformity of the fuzz should be as close to 100% as possible. When this indicator is equal to 100%, it indicates that the spacing between the warp and weft directions of the pile is equal. At this time, the pile surface is evenly distributed, plump, and without streaks, with a good flat pile style Application
