Velveteen fabric is a kind of wool fabric, which belongs to the higher-grade products in cotton fabrics. The surface of this kind of fabric is covered with raised piles. The pile height is generally about 1.2mm, forming a smooth pile surface, so it is called velveteen. Before the appearance of Chenille home textile fabrics, velveteen fabrics were the main materials for sand releases and curtain fabrics, but due to the relatively high price, the market was not wide. velvet.
The velveteen fabric has the following characteristics:
1. The abrasion resistance is 4-5 times higher than ordinary fabrics. Because the surface of the velveteen fabric is the fiber cross-section and contact with the outside world, to avoid friction at the bottom of the cloth.
2. The surface of the velveteen is densely covered with towering fluff, so the hand feels soft and has good elasticity, soft gloss and the surface is not easy to wrinkle.
3. The cloth body is thick, and the surface fluff can form an air layer, so the thermal insulation is good.
Therefore, velveteen fabrics are very popular among people and are often used in daily life and architectural decoration.
The velveteen fabric can be divided into warp velveteen and weft velvet according to the formation method of the pile. Warp velveteen is to cut the double layer of the fabric from the middle to form a single layer of fabric, which is processed by brushing and other post-processing; weft velveteen is to cut the weft and processing by brushing and other post-processing. Warp velveteen generally has long pile, complicated weaving process and many weaving defects, but high efficiency and simple weaving process; weft velveteen has thin texture, good hand feeling and luster, but the finishing process is more complicated. Most domestically produced velveteen fabrics are warp velveteen. Only a few factories have weft velveteen products.
The appearance of a good velveteen fabric product should meet the requirements of full and upright pile, even and dense, smooth and smooth suede, soft color, small direction, soft and smooth feel, and elasticity.
(2) Characteristic indexes of velveteen fabric
1. Coverage of cross section of fluff
The cross-sectional coverage of the pile is the percentage of the total cross-sectional area of the pile and the total area of the ground cloth. The high cross-section coverage rate of the pile indicates that the fullness of the pile is good.
2. Suede height
Suede pile height refers to the average height of single piles standing on the fabric surface after cutting pile. When the height of the pile is high, the pile surface is straight and the elasticity is poor, but the pile surface is relatively full.
3. Suede fullness
The fullness of suede refers to the volume of fluff per unit area of cloth. It includes two factors, the coverage of the fluff and the height of the fluff. The unit of suede fullness is "dense". The higher the "dense" number, the more plump the suede. Common suede velvet has a suede fullness of around 11 mils, and warp velveteen has a suede fullness of around 15 mils.
4. Consolidation tightness of fluff
The pile tightness means that the pile yarn is squeezed by the ground warp yarn and the pile warp yarn in the fabric structure. The greater the tightness of consolidation, the better the fastness of the fuzz consolidation and the less likely it is to depilate. The consolidation tightness of the weft velvet is expressed by the tissue tightness in the direction of the weft yarn, and its value is equal to the sum of the tightness of the fabric in the warp direction plus the tightness of the intersection point of the pile yarn and the warp yarn. The consolidation tightness of warp velvet indicates the degree to which the warp yarns are squeezed and compressed by the weft yarns in the fabric structure.
5. Uniformity of suede covering
The uniformity of the suede coverage is expressed by the ratio of the warp and weft spacing of the suede pile. It is an important indicator related to whether a good velveteen style can be obtained. The uniformity of the coverage 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 directions of the pile is equal. At this time, the pile is evenly distributed, full, without stripes, and has a good velveteen style.
