Abstract
The invention provides a flax straw degumming method. The method includes the processes of flax straw obtaining, grinding, acid pickling, ammonium acetate soaking, enzymic method degumming, potassium hydroxide washing, washing and drying. According to the acid pickling method, flax straw is processed through weak acid, fiber is not damaged, the degumming effect of enzymes can be promoted, the use amount of the enzymes is decreased, and the enzymic method degumming cost is reduced; degumming is conducted on the flax straw through pectinase which is high in specificity, causes no damage to fiber and is friendly to the environment. By means of the method, the long flax rate can be increased, softness, the split degree, uniformity, uniformity and other qualities of flax fiber can be improved, the production efficiency is high, and energy conservation and environment protection are achieved.
Description
Technical field
The invention belongs to textile fabric raw material disposal field, be specifically related to a kind of Degumming method of flax straw.
Background technology
Flax is a kind of ancient fiber and oil crops, and its fiber can be used for weaving, papermaking and composite.The process extracting fiber from flax straw is called flax degumming, and coming unstuck is the colloid polysaccharide utilizing microbial enzymes Partial digestion mesoglea, thus the process of release fiber.Come unstuck be linen fibre produce in restricted link.Generally adopt warm water to come unstuck and rain and dew Degumming method in current world wide, the warm water gained flax fibre quality that comes unstuck is better, but the foul odour environmental pollution produced due to anaerobe fermentation is serious, and fiber is also with foul smell.European countries' many employings rain and dew method, but gained fiber quality uniformity is poor, and the method limits by geographical conditions and temperature, humidity.In recent years, enzymatic degumming becomes the focus of researcher, and the price of enzyme becomes its bottleneck promoted of restriction.
The present invention adopts cheap, eco-friendly weak acid to carry out pre-treatment to flax straw, adopts pectase to carry out flax degumming, improves flax fibre quality and long flax rate, save the consumption of pectase, reduce sewage discharge, promote applying of enzymatic degumming.
Summary of the invention
Object of the present invention is: provide a kind of method that flax straw comes unstuck, and adopt weak acid preliminary treatment, pectase comes unstuck, the submissive process of potassium hydroxide, improves fiber quality and long flax rate, saves pectase consumption, reduce production cost, reduce sewage discharge and the pollution to environment.
Technical scheme: for achieving the above object, flax straw Degumming method of the present invention-a kind of, comprises following processing step:
(1) roll: by the process of flax straw mangle, make skin breakage.
(2) pickling: concentration is 20mmol/L, H
2sO
4solution or H
3pO
4solution, flax straw and acid solution are than being 1:20(w/v), the processing time is 24h.
(3) ammonium acetate buffer soaks: the flax straw control water after step (2) being processed, to without flowing out moisture, is soaked in 12h in pH5.0 ammonium acetate buffer.
(4) enzyme-addedly to come unstuck: pectase being diluted to enzyme activity is 1.0-1.5 μ/mL, and Xylanase activity is 0-0.5 μ/mL, and enzyme liquid is 15:1 with flax straw ratio (w/v), and temperature of coming unstuck is 30 DEG C-36 DEG C, and usually time is 24-30h.
(5) potassium hydroxide soaks: the flax straw after step (4) being processed is soaked in 1-2h in 0.1M/L potassium hydroxide solution.
(6) washing and drying: the flax straw washing after step (5) is processed, drying.
In step (1), preferred method is oscillation treatment.
Beneficial effect of the present invention is: a kind of flax straw Degumming method provided by the present invention adopts: the technological process of flax straw → roll → pickling → ammonium acetate immersion → enzymatic degumming → potassium hydroxide washing → washing → drying, before enzymatic degumming flax straw have passed through roll, pickling, ammonium acetate soak, saved the consumption of degummase.The H adopted
2sO
4solution or H
3pO
4solution concentration is weak acid, cheap, environmentally friendly, does not damage in decomposition flax while colloid to linen fibre.Present invention reduces production cost, also improve production efficiency.
