Flannel is a Fire retardant fabric with a rich and fluffy surface after being brushed. It can be divided into single-sided fleece and double-sided fleece.

Single-sided fleece is mainly twill weave, also known as serge; double-sided fleece is mainly plain weave. The flannel has a soft body, is comfortable to wear, and has good warmth retention. It is suitable for winter underwear and pajamas. Printed flannel and yarn-dyed striped flannel are suitable for women's and children's spring and autumn outerwear. The flannel printed with animals, flowers, and fairy tales are also called beibei velvet, which is suitable for children. Natural velvet, bleached velvet, mixed-color velvet, sesame velvet are generally used as winter clothing, gloves, shoes and hat clips, etc. The fleece fleece is formed by the repeated action of the steel wire needle point of the flossing machine, and a part of the fiber is pulled up on the surface of the gray fabric. The fleece is required to be short, dense and even. Printed flannels are brushed before printing, and bleached and variegated flannels are brushed at the end. The warp used for flannel grey cloth should be thin; the weft should be thick and have less twist. The cotton fiber used for spinning the weft should be thick and have good uniformity. The warp density of the fabric is small and the weft density is large, so that the weft yarns appear on the surface, which is conducive to the formation of plump and uniform fluff from the weft cotton fibers.

Flannel can be divided into velvet, velvet, flocked fabric, tufted fabric, polyester silk fabric flannel, knitted fabric flannel, cotton fabric flannel, velvet fabric flannel, warp knitted fabric cord flannel.

Among them, velveteen accounted for the vast majority.



The velveteen is woven with a pile tissue and then cut and finished. The surface has dense, flat, towering and shiny fluff, so it is called velveteen. The warp and weft of the velveteen are made of high-quality cotton yarn. The velveteen fluff is plump and flat, with thick texture, soft hand feeling, soft luster, abrasion resistance and durability, good warmth retention, elasticity, and not easy to wrinkle. According to different pile yarns, it is divided into warp velveteen (cut warp velveteen) and weft velveteen (cut weft velveteen). Warp velveteen is raised with warp yarns. Two sets of warp yarns (ground warp and pile warp) and one set of weft yarns are interwoven to form a double-layered fabric. After cutting piles, it becomes two single-layer warp velvets with flat piles. Warp velveteen ground weaves Plain weave is generally used, and the velvet warp consolidation is mainly based on the V-shaped unity method. The arrangement ratio of the ground warp and the velvet warp is 2:1 and 1:1.

Warp velveteen is divided into train velveteen and mercerized velveteen according to the length of the pile. Train velveteen has a long fluff and is often used as a train seat cushion; mercerized velveteen has a shorter fluff, which has been mercerized and has a bright cloth surface. It is often used for clothing, military collars and decorations. Weft velveteen is raised by weft yarn, which is made by interweaving one set of warp yarns and two sets of weft yarns (ground weft and pile weft), similar to corduroy. The ground weave is mostly plain weave, but also twill weave. The pile consolidation generally uses the V-type consolidation method, and the arrangement ratio of the ground weft to the pile weft is 1:3. The difference between it and corduroy is that the weft weft are arranged evenly in a certain pattern, and they are staggered by floating points. Therefore, the weft density is larger than the corduroy, the fabric is tight, and the pile is plump. Weft velvet is mainly used for clothing and decoration.
