Abstract
The invention discloses a composite swelling auxiliary agent. The composite swelling auxiliary agent comprises the following components in part by weight: 0.5 to 1 part of penetrating agent, 0.8 to 1.5 parts of swelling agent, and 0.5 to 1 part of auxiliary agent which dissolves gelatine in a fiber, wherein the auxiliary agent for dissolving gelatine in the fiber is acid, alkali or biological enzyme. After bast fibers are biochemically degummed, and before the bast fiber are mechanically thinned, the composite swelling auxiliary agent can effectively dissolve a part of the gelatine in the fiber, effectively penetrates into the fiber and weakens the cohesive force between single fibers, so the whole structure of the fiber becomes more loose, the surface smoothness of fibers is improved at the same time, the fibers are more likely to crack or slide under the action of an external force, the effectiveness of mechanical effect is improved, and the fiber fineness is improved. The expansion ratio of the bast fiber processed by the composite swelling auxiliary agent can be up to 17.3 percent and is 1.5 to 2 times that of the bast fiber processed by a conventional emulsifier, amino-modified silicone oil, and the like, the gelatine removing rate can be up to 86.5, the fiber fineness can be up to 620Nm, the strength can be up to 2.96cN/dtex, and the requirements of textile processing can be completely met.
Description
Technical field
The present invention relates to a kind of compound swelling auxiliary agent, particularly a kind of become more meticulous compound swelling auxiliary agent of process technology of flax fibre that is used for.
Background technology
At present, the process of refinement of the fiber that essence such as the process of refinement of flax fibre, particularly jute, bluish dogbane, sisal hemp are harder, thick is the insoluble problems of people always.Though at Granted publication number for disclosing a kind of preparation method of refined jute-kenaf fibres in the patent document of CN1141325C, 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, and the application performance in high-grade fabric is not good especially.Above-mentioned patent documentation also discloses oil supply A and the step of oil supply B before mechanical shredding step, but the concrete oil substances of giving in the oil supply step openly.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 then, and it only can play level and smooth and soft effect to the flax fibre surface.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
In order to overcome above-mentioned deficiency, technical problem to be solved provides a kind of flax fibre that is applied in through behind the biochemical degumming, before the mechanical refinement step, improves the fineness of fiber and the compound swelling auxiliary agent of spinning property just in the present invention.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is following:
A kind of compound swelling auxiliary agent is characterized in that: the component that comprises following parts by weight: bleeding agent 0.5-1 part,
Auxiliary agent 0.5-1 part of colloid composition in swelling agent 0.8-1.5 part, the dissolving fiber.
The auxiliary agent of colloid composition is preferably acid, alkali or biology enzyme in the said dissolving fiber.
It is the concentrated sulfuric acid more than 85% that said acid is preferably mass concentration.It is the NaOH more than 90% that said alkali is preferably mass fraction.Said biology enzyme is preferably one or more in laccase, pectase, the cellulase.
Preferably, this compound swelling auxiliary agent also includes 1 part of amido silicon oil.
Said bleeding agent is selected from one or both in bleeding agent PST or the penetrating agent JFC.
Said swelling agent is selected from one or more among swelling agent PP, swelling agent P or the swelling agent OP.
Beneficial effect: compound swelling auxiliary agent of the present invention is applied in flax fibre through behind the biochemical degumming, before the mechanical refinement step, can effectively dissolve colloid in the part fiber; And efficiently infiltrate through fibrous inside, and slacken the cohesive force between the filament, make the fabric integer structure become looser; Improve 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; The expansion rate of the flax fibre of handling through compound swelling auxiliary agent can reach 17.3%; Be 1.5-2 times after conventional emulsifier, amido silicon oil etc. are handled, the colloid clearance can reach 86.5, and fibre fineness can reach 620 public; Brute force reaches 2.96cN/dtex, can satisfy the requirement of weaving processing fully.
