Abstract
The invention relates to a method for degumming flax roving by using biological enzyme. The method comprises the following steps of: confecting an enzyme liquor by using water, 1.5-2.5g/L of biological enzyme and 1.0-1.5g/L of sodium carbonate at the pH (potential of hydrogen) value of 9-10 and under the temperature of 50-60 DEG C; mixing the enzyme liquor and the flax roving at the bath ratio of 1:8, circulating at the temperature of 50-60 DEG C for 30-90min, and then, discharging the liquor; adding water to wash, circulating at the temperature of 50-110 DEG C for 5-15min, and then discharging the liquor; and adding water to wash, circulating at the temperature of 20-80 DEG C for 5-15min, and then, discharging the liquor to finally finish the degumming treatment. According to the invention, the flax roving is degummed by using the biological enzyme, so that the spin ability of the roving is improved, the strength of the roving is enhanced, and meanwhile, the environment pollution is avoided.
Description
Technical field
The present invention relates to a kind of rough linen yarn bio-enzyme Degumming method.
Background technology
Linen fibre is the human a kind of native cellulose fibre that uses the earliest.At present, flax spinning generally adopts the wet spinning form, and its rove will pass through the chemical Degumming manufacturing procedures such as kiering, bleaching.Flax roving chemical degumming technique purpose mainly is to remove the impurity such as part pectin, lignin, improves the division degree of linen fibre, and then improves the spinnability of flax process of fiber.In the degumming tech that the chemical kiering of flax roving is bleached, adopt caustic scouring, chlorite bleaching, hydrogen peroxide bleaching (inferior-as to itch and float).The contaminated wastewater that this technique forms is managed than refractory, and environmental pollution is serious; In addition, this technique is large to the linen fibre damage, broken ring resultant yarn ability.
Summary of the invention
The purpose of this invention is to provide a kind of rough linen yarn bio-enzyme Degumming method.
For achieving the above object, the technical solution used in the present invention is:
A kind of rough linen yarn bio-enzyme Degumming method may further comprise the steps:
(1), enzyme liquid preparation:
Water;
Biology enzyme: 1.5-2.5 g/L;
Sodium carbonate: 1.0-1.5 g/L;
PH value: 9-10;
Temperature: 50-60 ℃;
(2a), enzyme liquid is mixed bath raio with flax roving: 1:8, temperature 50-60 ℃, discharge opeing after circulation 30-90 minute;
(2b), add water washing, temperature 50-110 ℃, discharge opeing after circulation 5-15 minute;
(2c), add water washing, temperature 20-80 ℃, discharge opeing after circulation 5-15 minute, and finish and come unstuck.
Preferably, described biology enzyme is a kind of of pectase, zytase or mixes.
Preferably, the specific activity of described biology enzyme is 4000-6000u/g.
Because technique scheme is used, the present invention compared with prior art has following advantages:
The present invention has improved the spinnability of yarn by using biology enzyme to come unstuck to carrying out flax roving, has improved the intensity of yarn, has avoided simultaneously the pollution of environment.
