Dyeing method for cool ultrahigh-molecular-weight polyethylene bedding

Abstract

The invention discloses a dyeing method for cool ultrahigh-molecular-weight polyethylene bedding. The dyeing method comprises the following steps: weaving; pre-setting; cold dyeing; washing and dehydrating; baking; and preparation of a finished product. The method gives full play to the respective performance advantages of ultrahigh-molecular-weight polyethylene and viscose fibers and allows the functions of ultrahigh-molecular-weight polyethylene and viscose fibers to complement each other for development of a high-grade cool bedding fabric; and ultrahigh-molecular-weight polyethylene and viscose fibers are blended according to a ratio of 35: 65, blended yarns with fineness of 18.5 tex are used as a raw material for warp and weft yarns, and reasonable fabric specification and process design are selected, so a prepared product has a smooth cloth surface, moisture-absorption performance, air permeability and soft and tough texture, feels cool and comfortable, can be easily to clean andis a high-grade fabric for summer quilts. According to the invention, only 65% of viscose fibers are dyed, so fried-dough-twist-like dyeing effect is obtained, and the problem that ultrahigh-molecular-weight polyethylene cannot be dyed is overcome. The dyeing method employs a cold dyeing process, does not need heating during dyeing, saves energy, reduces cost, and is clean and environment-friendlyin production.

Description

technical field [0001] The invention belongs to the field of fabrics in the textile industry, and in particular relates to a method for dyeing cool-feeling ultra-high molecular weight polyethylene bedding. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is a high-performance fiber that was industrialized in the 1980s, also known as high-strength and high-modulus polyethylene (PE) fiber. The performance characteristics of UHMWPE fiber, such as high relative molecular mass, high orientation, highly entangled molecular chains and high crystallinity, endow the material with excellent comprehensive performance, with low density, high modulus, UV resistance, wear resistance, impact resistance, High strength and other properties, it has the best cost performance among the three existing fiber materials. Ultra-high molecular weight polyethylene (UHMWPE) fibers, UHMWPE fibers have extremely high crystallinity, lack of dyeing groups, and are diffi...

Problems solved by technology

The performance characteristics of UHMWPE fiber, such as high relative molecular mass, high orientation, highly entangled molecular chains and high crystallinity, endow the material with excellent comprehensive performance, with low density, high modulus, UV resistance, wear resistance, impact resistance, High strength and other properties, it has the best cost performance among the three existing fiber materials. Ultra-high molecular weight polyethylene (UHMWPE) fibers, UHMWPE fibers have extremely high crystallinity, lack of dyeing groups, and are difficult to dye. At present, the main research institutions , adopts methods such as stock solution coloring method, conventional dyeing method, development of specific dye structure, special dyeing process, etc., but the color fastness is not up to standard, and the chromatogram is incomplete, which cannot meet the requirements of mass production
