Problems solved by technology

In the prior art, the lye mainly uses NaOH, the amount of NaOH and the type and amount of scouring aids have a great relationship with the removal of colloidal substances in the raw hemp, thus affecting the quality of the fiber
The use of NaOH in the prior art is relatively large, the selection and usage of scouring agent and some process parameters are not appropriate, resulting in long scouring time, poor fiber quality after degumming, and even unclean removal of colloidal substances. Therefore, need provide a kind of ideal ramie degumming method

Abstract

The invention discloses a ramie degumming method which comprises the following steps: 1, treating raw ramie to soften the raw ramie into strip-shaped soft ramie; 2, carrying out primary treatment by using facultative anaerobic degumming bacteria to obtain a primarily treated ramie material; 3, soaking the primarily treated ramie material obtained in the step 2 with sulfuric acid; 4, washing the ramie material with water to remove gum impurities, and draining off water; 5, preparing a boiling-off liquid, and adding the boiling-off liquid for boiling off; 6, washing the boiled-off ramie materialwith water, removing gum impurities, and draining off water; 7, beating and washing to remove residual gum on the ramie material; 8, carrying out dehydration treatment; 9, preparing a scouring solution, and adding the scouring solution for scouring for 2-3 hours; and 10, cleaning the scoured ramie material, dehydrating, feeding oil and drying. The ramie degumming method provided by the inventionhas the advantages that the boiling-off time is shortened, the boiling-off burden is greatly reduced, the consumption of alkali is reduced, the technological process is simple, and the gum in the rawramie can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of cloth production and processing, and more specifically relates to a method for degumming ramie. Background technique [0002] my country is a big producer of hemp, and its planting area and hemp fiber output rank among the top in the world. In 2007, my country's ramie output reached 277,000 tons, and all hemp products reached 600,000 tons. Ramie is known as "Chinese Grass" in the world. It is an important worsted fiber crop second only to cotton, and it is also a unique traditional characteristic crop in my country. Ramie (Boehmeria), also known as wild hemp, home hemp, green hemp, white hemp, belongs to Rosaceae, Urticaceae, and Ramie. Among all kinds of plant fibers, ramie has the best fiber quality, and the ramie fiber is tough. The textiles processed by it have many excellent qualities such as antibacterial, sweat-absorbing and anti-ultraviolet rays. They are deeply loved by consumers and can be use...
