Description

Preparation method of imitation velvet fabric and fabric thereof Technical Field The invention relates to the technical field of textile, in particular to a penguin-like velvet fabric and a preparation method thereof. Background With the upgrading of consumption, the market demand of the velvet fabric is developed from single warmth retention to high touch experience. Penguin is a very living bird, and its feathers are soft, very dense and silky to the touch. The existing imitation velvet fabric mainly comprises plush, coral velvet, flannel and other products. The conventional fabric on the market generally reduces the fiber twist or adopts fine denier fibers to realize soft hand feeling, but the pilling tendency is obviously increased, and if the pilling resistance grade is improved through resin finishing, the softness is sacrificed, namely the balance between the softness and the high pilling resistance grade is difficult to realize by the conventional fabric. Therefore, there is a need to prepare a penguin feather-like bionic fabric with excellent softness and high anti-pilling grade. Disclosure of Invention The invention aims to solve the problem that the existing fabric is difficult to realize balance of excellent softness and high anti-pilling grade, and provides a penguin-like suede fabric and a preparation method thereof. In a first aspect, the invention provides a preparation method of a velvet fabric, which comprises the following steps: (1) Weaving, namely warping and weaving face yarn, ground yarn and connecting yarn on a double-needle bar warp knitting machine to obtain double-layer grey cloth with connecting lines in the middle; (2) Slitting, namely cutting the grey cloth with the connecting line in the middle of the double layers to obtain two grey cloths; (3) Presetting, namely carrying out presetting treatment on the cut grey cloth; (4) Ironing, namely ironing the pre-shaped grey cloth; (5) Dyeing and/or printing, namely dyeing or printing the scalded grey cloth; (6) Drying, namely drying the dyed and/or printed grey cloth; (7) Intermediate shaping, namely performing intermediate shaping treatment on the dried grey cloth; (8) The napping finishing comprises carding treatment; (9) Blowing, namely blowing the napped grey cloth; (10) Final shaping, namely performing final shaping treatment on the grey cloth after the wool blowing; The hair blowing treatment mode comprises a first hair blowing treatment, a second hair blowing treatment and a third hair blowing treatment which are sequentially carried out, wherein the hair blowing angle of the first hair blowing treatment, the hair blowing angle of the second hair blowing treatment and the hair blowing angle of the third hair blowing treatment are sequentially reduced. According to the invention, the fabric prepared by the preparation method can simultaneously realize the silky touch feeling of penguin feather level, the softness of cashmere level, the anti-pilling performance of superior products and the warmth retention performance of down level, further, the weaving internal stress is eliminated through the pre-shaping to stabilize the grey cloth foundation structure, the softening agent is fully adsorbed by the fiber in a loose state through the intermediate shaping to ensure the softness of the suede, and then a protective film can be formed on the suede through the final shaping, so that the prepared fabric can synchronously realize the comprehensive increase of the anti-pilling grade and the softness. As a preferable technical scheme of the invention, the face yarn is a fine denier porous polyester filament yarn with the specification of 120D/192f or 150D/288f. The face yarn is used for forming a suede, and can endow the fabric with a silky touch. As a preferable technical scheme of the invention, the ground yarn is polyester FDY filament yarn with the specification of 75D/36f. The ground yarn is used for forming a base fabric framework, so that the fabric has better dimensional stability. As a preferable technical scheme of the invention, the connecting yarn is polyester filament yarn, and the specification is 75D/36f polyester FDY. The connecting yarn in the present invention is used to form a connecting yarn between the double needle beds. As a preferred technical scheme of the invention, the mass ratio of the face yarn, the ground yarn and the connecting yarn is (65-75): (20-25): (5-15), preferably (70-75): (20-25): (5-10). The dosage of the face yarn, the ground yarn and the connecting yarn is controlled within the range, so that the prepared fabric has the penguin feather-grade smooth touch feeling and also has excellent dimensional stability and suede uniformity. The warping in the step (1) is a process of winding the face yarn, the ground yarn and the connecting yarn in a package form on a warp beam in parallel, so that the stability and the suede uniformity of a fabric organization structure can be ensured, the warping is perfor
