Abstract

The invention discloses a preparation method of a Raschel blanket made of Wuhong yarn fiber. The steps are as follows: (1) Weaving: using Wuhong yarn fiber as plush yarn, polyester full-drawn yarn as bottom yarn, and using full-wearing same-direction (2) Pre-finishing: Pre-finish the gray cloth after pre-shaping along the wool, pre-ironing against the wool, high combing along the wool, and alternating ironing against the wool to obtain the pre-finishing (3) Dyeing and finishing: the gray cloth after pre-finishing is dyed in reverse wool, washed and softened, and then dehydrated to obtain the dyed and finished gray cloth; (4) Finishing: The gray cloth after dyeing and finishing is dried and shaped, smoothed Wool combing, reverse wool fluffing, front ironing, front ironing, back ironing, back ironing, cutting and sewing to obtain the Wuhong yarn fiber raschel blanket. The invention adopts the rainbow yarn fiber with good dyeability as a raw material, and can prepare a raschel blanket with various colors and high color fastness, which fully meets the market demand.

Description

technical field [0001] The invention relates to the technical field of blanket production, in particular to a preparation method of a Wuhong yarn fiber Raschel blanket. Background technique [0002] Raschel blanket is a kind of blanket made of acrylic yarn as raw material, woven on Raschel warp knitting machine, and made by splitting, printing, finishing and sewing. Raschel is one of the latest and best-selling fabrics among acrylic fibers. It is characterized by soft hand feeling, delicate texture and environmental protection. It is mainly used for high-end quilt blankets, fur coat trim decorations, high-end fabric toys, car decorations, and warm clothes and hats. Clothing, etc., comfortable, breathable and warm. [0003] But take acrylic fiber as raw material to prepare raschel blanket cost higher, for reducing production cost, released the raschel blanket based on polyester on the market. For example, "a raschel blanket and its production method" disclosed in the Chines...
