Grass cloth processing process

Abstract

This invention discloses one grass cloth processing method. It causes H2O2 to carry on chemistry blanch front processing and acidic cellulase carries on the enzyme preparation post-processing blanch reorganization grass cloth gray clothes. Chemistry blanch front processes carries on two times, H2O2 joins the quantity for to process according the rate of the cotton material weight 20 - 30%, but also joins the processing cotton material weight's 3 ~ 5% stabilizer Na2Sio3.9H2O2, bath to compare 1: 25 ~ 30, temperature 95 ~ 100 DEG C, total blanch time is 35 ~ 45 minutes; When enzyme preparation post-processing the acidic cellulase joins the quantity for process according the rate cotton material weight 1.0 ~ 2%, the bath compares 1: 15 ~ 20, temperature 48 ~ 52 DEG C, pH value 4.5 ~ 4.8, process time is 10 ~ 20 minutes; Afterwards carries on inactivate, inactivate when adjusts the pH value to 9.0, temperature 80 DEG C, time 15 ~ 20 minutes. Uses this invention method can be able basically to eliminate grass cloth embryo cloth's sol, the red root, the spot fault, the solution grass cloth rigidity is hard, has the itch feeling question; Process time short, even, has processed the grass cloth is easy to colour; no pollution, remains without the chemical agent.

Description

technical field [0001] The invention relates to a treatment method for linen fabrics, in particular to a method for bleaching and dyeing grass cloth greige by adopting chemical bleaching pretreatment and biological enzyme preparation posttreatment technology. Background technique [0002] Grass cloth is a kind of hemp woven plain cloth, which is handmade or semi-handmade ramie cloth, and also made of hemp. When weaving linen, the warp and weft yarns may be made by hand or warp yarns are machine-made, and the weft yarns are made by hand. Before weaving linen, the raw hemp must be soaked and rinsed before weaving. Currently, the soaking and rinsing methods still used include water bleaching, sunlight rinsing, dew bleaching, lime water bleaching, charcoal fumigation, and cow dung dipping. The grass cloth produced by the above dipping and rinsing method is a raw hemp product that has not been degummed. There are colloids, red roots, spots and other sundries on the cloth, so it ...

Problems solved by technology

But whether it is South Korea or my country's current domestic grass cloth bleaching and dyeing, chemical bleaching and dyeing is basically adopted, adding H 2 o 2 At the same time, chemical substances such as ramie degumming aids and emulsified oil were added, which caused serious environmental pollution and high cost. The processing cost of each piece of grass cloth reached 5 US dollars, and there were many disadvantages such as unstable quality and difficult coloring.
