Tufted flannel: cotton fabric with rich and fluffy surface after raising. Through the needle-hole tufting process on the fabric surface, more fluff is produced, which has strong stereoscopic impression, high gloss and soft and thick hand feeling. It is characterized by cotton fabric with rich and fluffy surface.
Tufted velvet is divided into single-sided velvet and double-sided velvet. Single-sided velvet knitting is mainly twill, also called serge velvet; Double-sided cashmere is mainly plain. The pile-up of flannel is formed by the repeated action of the steel wire needle tip of the pile-up machine and pulling up some fibers on the surface of the grey cloth, which requires the pile to be short, dense and uniform. Printed flannel is brushed before printing, and bleached mottled flannel is brushed at the end. The warp yarns used for flannel grey cloth should be thin; Weft should be thick and twist should be small. The cotton fiber of weft yarn should be thick and uniform. The warp density of the fabric is small and the weft density is large, which makes the weft emerge on the surface, which is beneficial to the formation of full and uniform fluff of weft cotton fibers. The weft strength of flannel is greatly lost after napping, so it is very important to master the quality of cotton yarn and the operation of napping process.
