Description
Technical Field
The invention relates to the technical field of textile fabrics, in particular to a preparation method of an eight-comb sanded flannel fabric.
Background
The fabric is a material for making clothes, and as one of three elements of the clothes, the fabric can not only explain the style and the characteristics of the clothes, but also directly control the expression effects of the color and the shape of the clothes. In the world of clothes, the fabric of the clothes is various and different day by day, but in general, the high-quality and high-grade fabric has the characteristics of comfortable wearing, sweat absorption, air permeability, stiff and smooth suspension, noble vision, soft and beautiful touch and the like.
Sanding is a method for finishing the fabric, namely, a sanding roller is used for rubbing the cloth surface to grind a layer of fluff on the cloth surface. The sanded textile fabric has the advantages of thick texture, softness, comfort, strong drapability, easy nursing, plump suede and softness and comfort when being worn. The utility model is soft, warm and comfortable in winter. The fabric has the advantages that the original performance of the fabric is kept, the fabric surface is enabled to form a layer with the feeling of a short fluff layer, the heat conductivity of the sanded fabric is reduced, the heat retention property and the softness are increased while the new style is given to the fabric, the color and luster are striking, the hand feeling is soft, the appearance is full and pleasant, and in addition, the sanded fabric has the advantages of being not easy to fade and pilling.
The flannel is a soft and suede cotton wool fabric woven by coarse cotton wool yarns, and the inner part of the flannel is covered by a layer of plump and fine and clean villi, so that the flannel does not expose texture, and the flannel has soft and smooth hand feeling. The flannel has high gram weight, fine and dense plush, thick fabric, high cost and good heat retention, and is widely applied to men and women's coats, children's garments and home textiles at present. The production of the existing flannel is that part of wool is dyed, then part of original color wool is mixed, blended and spun into mixed color wool yarn, and the mixed color wool yarn is woven into fabrics, and then the fabrics are made through fulling and napping. Twill weave is mostly adopted, and plain weave is also used. The raw materials except the whole wool are generally wool-viscose blended yarns, and a small amount of nylon fiber is mixed in some of the raw materials to improve the wear resistance. The surface fluff of the existing flannel generally adopts polyester elastic yarn as an implantation material of the fluff, and the hand feeling of the fluff is still different from the real cashmere.
The invention patent ZL201010160815.8 discloses a flannel fabric, which mainly comprises yarns, and is formed by warp knitting of the yarns, and is characterized in that the yarns are polyester low stretch yarn DTY, the titer of the polyester low stretch yarn DTY is 40D-100D, the number specification of single filaments is 144F-576F, the basic weaving tissue of the flannel fabric is a warp plain tissue, and the flannel fabric is napped on two sides or one side, and can form a napping surface after napping. Similarly, the flannel adopts terylene chemical fiber, which can not reach the hand feeling of cashmere.
Common sanding fabrics on the market generally take yarn-dyed fabric as a raw material, and adopt a common sand paper sanding method, and the products are mainly household articles in winter. The process flow comprises the following steps: washing, pre-shaping, rolling, dyeing, drying, sanding, post-shaping and finished inspection. The warp knitting elastic fabric produced by adopting a common sanding machine and the existing process flow has relatively uniform plush on the cloth surface, but has insufficient fineness and insufficient bright color, is easy to generate horizontal bar defects in the sanding process, has difference in fabric edges, and is not suitable for being used as a high-grade underwear fabric.
Therefore, the eight-comb sanded flannel fabric which is low in cost, close to cashmere in hand feeling, good in heat retention and flexibility, striking in color and luster, soft in hand feeling, full and pleasant in appearance, meets the market demand, and has high economic value, social value and ecological value is developed.
