Abstract

The invention discloses a preparation method of a dancing rainbow yarn fiber Raschel blanket. The preparation method comprises the following steps of (1) weaving: performing weaving on a high-speed warp knitting machine by adopting dancing rainbow yarn fibers as plush yarns and polyester fully-drawn yarns as bottom yarns in a full-penetration same-direction yarn laying manner to obtain a gray fabric; (2) pre-finishing: carrying out wool smoothing pre-shaping, wool reversing pre-lustring, wool smoothing high carding, and wool reversing and wool smoothing alternating lustring on the gray fabricto obtain a pre-finished gray fabric; (3) dyeing and finishing: carrying out wool reversing dyeing on the grey cloth subjected to pre-finishing, washing with water, performing softening and dehydrating to obtain dyed and finished grey fabric; and (4) after-finishing: enabling the dyed and finished gray fabric to be subjected to drying and shaping, wool smoothing and wool reversing, wool reversingfluffing, front face lustring, front face ironing and shearing, reverse face lustring, reverse face ironing and shearing and then to be tailored and sewn, and obtaining the dancing rainbow yarn fiberRaschel blanket. The dancing rainbow yarn fiber with good dyeability is adopted as the raw material, the Raschel blanket with diversified colors and high color fastness can be prepared, and the marketrequirements are fully met.

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...
