Features of velveteen fabric！
1. The abrasion resistance is 4-5 times higher than that of general fabrics. Because the surface of the velveteen fabric is in contact with the outside of the fiber section, it avoids friction at the bottom of the cloth.
2. The surface of the velveteen is densely covered with towering piles, so it feels soft and has good elasticity, soft luster, and the surface is not easy to wrinkle.
3. The cloth body is thick, and the fluff on the surface can form an air layer, so it has good warmth retention.
Therefore, velveteen fabrics are very popular and are often used in daily life and architectural decoration.
(1) Appearance
The appearance of a good velveteen fabric product should meet the requirements of plump upright, even and dense pile, smooth and smooth suede, soft color, low directionality, soft and smooth hand feeling, and full of elasticity.
(2) The characteristic index of velveteen fabric
1. Cross-section coverage of fluff
The section coverage of the pile is the percentage of the sum of the section area of the pile and the total area of the ground cloth. The high cross-sectional coverage of the pile indicates that the suede has a good degree of fullness.
2. Suede pile height
The pile height refers to the average height of a single pile standing on the surface of the fabric after cutting pile. When the height of the pile is higher, the suede is straighter and less elastic, but the suede is more plump.
3. Suede fullness
The fullness of the suede refers to the volume of the pile on the ground cloth per unit area. It contains two factors: the coverage of the fluff and the height of the fluff. The unit of suede fullness is “density”. The higher the “density” number, the more plump the suede. The suede fullness of common weft velveteen is about 11 densities, and the suede fullness of warp velvets is about 15 densities.
4. Consolidation tightness of fluff
The pile consolidation tightness refers to the degree to which the pile yarn is squeezed by the ground warp and the pressed pile warp in the fabric structure. The greater the consolidation tightness, the better the consolidation fastness of the fluff, and the less likely it is to shed hair. The consolidation tightness of the weft velveteen is expressed by the weft tightness in the direction of the pile weft, and its value is equal to the warp tightness of the fabric plus the tightness of the interweaving point of the pile yarn and the warp yarn. The pile consolidation tightness of warp velveteen indicates the degree to which the pile warp yarn is squeezed by the weft arrangement in the fabric structure.
5. Evenness of suede coverage
The uniformity of suede coverage is expressed by the ratio of the space between the warp and weft of the suede. It is an important indicator related to whether a good velveteen style can be obtained. The coverage uniformity of the fluff is as close to 100% as possible. When the index is equal to 100%, it means that the distance between the warp and weft of the pile is equal, and the pile is evenly distributed, plump, and has no streaks, and has a good velveteen style.
