Abstract

The invention discloses a manufacturing process of grass cloth. The process comprises the steps of pre-stage preparation, degumming, warp yarn preparing, weaving, bleaching, dehydrating, dyeing, finishing, and packaging. According to the invention, ramie is subjected to the degumming process by using bacillus alcalophilus, such that ramie residual gum content can be effectively reduced, product safety is improved, and cloth dye uptake can be improved. With modification upon the bleaching process, cloth color stability is ensured, and bleaching duration can be reduced, such that working efficiency can be improved. The grass cloth manufacturing process provided by the invention is advantaged in low environmental pollution, high dye uptake, high color fastness, and short dyeing duration. With the process, economic benefit can be improved. The process is suitable for industrialized productions.

Description

technical field [0001] The invention relates to a fabric making process, in particular to a grass cloth making process. Background technique [0002] As ramie is a characteristic textile raw material with resource monopoly in our country, its output accounts for more than 90% of the world's ramie fiber output, so it is called "Chinese grass". Grass cloth woven from ramie has the advantages of roughness, crispness, elegance, lightness, coolness, breathability, antibacterial, etc., and is known as the "king of natural fibers". However, the current process of producing linen is complicated, the production cycle is long and the produced linen cannot overcome the rough feel of ramie itself, and has gradually failed to meet the quality and quantity needs of consumers. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the deficiencies of the prior art and provide a method for making linen that is comfortable to wear, has a s...
