Abstract
The invention discloses a refining processing method of fibrilia. The method comprises the following steps of: performing water bath or acid bath on crude hemp; performing chemical degumming treatment by use of sodium hydroxide solution; performing bio-enzyme degumming by use of pectinase or laccase; performing fiber expansion treatment on the fiber by use of a composite expansion auxiliary; performing mechanical refining treatment on the fibrilia after the expansion treatment; and finally, sequentially washing, dehydrating and airing the fibrilia to obtain the refined fibrilia. Through the invention, the cohesive force among single fibers is weakened, the overall structure of the fiber becomes looser, and meanwhile, the surface smoothness of the fiber is improved so that the fiber cleaves or slides more easily under the effect of external force, thereby improving the effectiveness of mechanical effect and enhancing the fiber fineness and strength.
Description
Technical field
The invention belongs to the Textile Engineering field, particularly a kind of processing method that becomes more meticulous of flax fibre.
Background technology
At present; The process of refinement of flax fibre; Particularly the process of refinement of harder, the thick fiber of essence such as jute, bluish dogbane, sisal hemp is the insoluble problems of people always; The preparation for processing of the flax fibre of prior art, promptly by retted fibre step, chemical Degumming step, mechanical shredding step, three processing methods that step is formed; But the jute-kenaf fibres pliability and the spinnability thereof that in fact obtain through this preparation method are still undesirable; Application performance in high-grade fabric is not good especially, and in present existing treatment technology to flax fibre, the oil substances of giving of flax fibre generally all adopts emulsifying agent, amido silicon oil or other softeners; It only can play level and smooth and soft effect to the flax fibre surface, and this also is the reason that the fibre finenesses of flax fibre after process of refinement such as jute, bluish dogbane, sisal hemp can not reach desired result.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of retrofit technology of flax fibre is provided, to improve fineness, intensity and the utilization rate of fiber.
Technical scheme: in order to realize above purpose, the processing method that becomes more meticulous of a kind of flax fibre of the present invention, concrete steps are following:
(1) after raw ramie carries out water-bath or acid bath, adopts sodium hydroxide solution to carry out chemical Degumming and handle;
(2) adopt pectase or laccase to carry out biological enzyme degumming;
(3) adopting composite expanded auxiliary agent that fiber is carried out filament expansion handles;
(4) flax fibre after the expansion process carries out mechanical thinning processing;
(5) flax fibre is cleaned in regular turn, dewaters, dries promptly get the flax fibre that becomes more meticulous.
Described composite expanded auxiliary agent is made up of the auxiliary agent of colloid composition in bleeding agent, swelling agent, the dissolving fiber, and its mass ratio is 1:1:1.
The auxiliary agent of colloid composition comprises in the described dissolving fiber: concentration is a kind of in the concentrated sulfuric acid, NaOH or the biology enzyme of 85%-95%.
The filament expansion treatment step comprises: earlier with 10 times of water composite expanded auxiliary agent being diluted to the aqueous solution, is 1:20-1:30 then with the bath raio, and temperature is 50-60 ℃, and the time is flax fibre to be handled in 0.5-4 hour.
Described mechanical refinement comprises mechanical carding and two steps of mechanical commutation draft; Described mechanical carding adopts the close special-purpose Bearded-needle knitted cloth of high tooth depth; Reduce cylinder speed, improve the speed ratio of cylinder and licker-in, fiber is applied branch comb power make it produce horizontal splitting; Described mechanical commutation draft adopts double drafting system; Fiber after the cylinder combing at first passes through at draw ratio and the first less draw zone of roller gauge, again through draw ratio and the second bigger draw zone of roller gauge, fiber is applied tensile force make it produce straight skidding.
Beneficial effect: the retrofit technology of a kind of flax fibre of the present invention has slackened the cohesive force between the filament, and makes the fabric integer structure become looser, improves the fiber surface smoothness simultaneously; Make fiber more be easy to generate splitting or slippage under external force, thereby improve the validity of mechanism, improve fibre fineness and intensity; The expansion rate of the flax fibre after expansion process can reach 17.3%, is 1.5-2 times after conventional emulsifier, amido silicon oil etc. are handled, and the colloid clearance can reach 86.5; Fibre fineness can reach 620 public; Though powerful decline to some extent, but still can reach 2.96cN/dtex, can satisfy the requirement of weaving processing fully.
