Abstract
The invention relates to a chemical preprocessing agent for the physical refinement of wool. The chemical preprocessing agent comprises, by weight, 0.01-1.5% of a swelling agent, 1.5-18% of a chain opening agent, 0.1-5% of a lubricant, and the balance water. By adopting the chemical preprocessing agent of above scheme, wool macro-molecule side groups are fully puffed, disulfide bonds between the molecules are broken up by a reductant, and internal stress between the wool macro-molecules is rapidly reduced to conveniently cooperate a wool stretching device, so twisted fibers or twistless fibers can be mechanically stretched under humid and hot conditions, and novel wool fibers with the silk-like luster and cashmere-like touch can be produced.
Description
(1) technical field
The present invention relates to a kind of chemical treatments, particularly relate to a kind of chemical pretreating reagent that is used for the wool physical thinning.
(2) background technology
The wool fibre that the physical thinning wool fibre is a kind of refinement, it is that common wool fibre is carried out mechanical stretching under suitable chemical assistant and wet heat condition, the refinement fiber after will stretching again carries out heat and chemical style-setting and a kind of tencel of forming.This fiber can reduce by 2～4 μ m with common wool fineness, and length increases about 50%.Because the variation in wool cross section after the refinement; The reinforcement of intermolecular force and the factors such as change of surperficial scale; Make it form a kind of feel as the gloss and cashmere that has as the real silk, have the character of silkete unshrinkable wool concurrently, form complementary tencel to the cashmere fracture strength is low again simultaneously.Its feel of lining and the outward appearance aspect that go out with this fiber production have increased new aesthetic feeling, and its fabric has unique style and features, and subjective assessment is thought: physical thinning wool product feel is like cashmere, the outward appearance likelihood seemingly, comprehensively style more approaches a wool product style.The same thick, the spinning woven and knit product of various wools that is processed into common wool.Therefore lightening, the superior trend of current wool textile has been complied with in the appearance of this fiber, has very big development potentiality.
The big molecule of wool fibre is the chain macromolecule that is formed by connecting with amido link (claiming peptide bond again) multiple a-amino acid, and the amino acid between the different molecular chain can also form and can form spaces such as disulfide bond, salt type bond and hydrogen bond between a large amount of hydrogen bonds, wool macromolecular main chain and laterally be connected.The unimolecule space form of wool macromolecular chain has two big types usually; One type is helical form; Generally the wool fibre unimolecule exists with alpha-helix chain state, and when wool fibre received the certain conditions processing, the molecule-type shape was become the β type structure of elongation by α-type; The transformation of this space structure makes wool possess the potentiality that are stretched.Can change the α type structure in the wool fibre molecular structure into β type structure through the method that stretches, and wool fibre is remained on the state after the elongation more muchly.In order to realize and keep the transformation of fibre configuration, must manage to take apart the cross key of getting in touch between the macromolecular chain, fully reduce tensile stress, stretching and refinement are achieved.Research shows: fibre bundle is immersed suitable chemical assistant; Make it wetting fully, expanded; And break its inner various salt type bonds, hydrogen bond and disulfide bond; Under suitable temperature, damp condition, twisting or non-twist fiber are applied certain mechanical force stretch, keep the stable requirement that can reach the wool physical thinning through heat and the chemical style-setting form after with its elongation again.
(3) summary of the invention
The present invention is based on above-mentioned purpose, a kind of chemical pretreating reagent that is used for the wool physical thinning is provided.
Technical scheme of the present invention is to realize like this.
Wool physical thinning of the present invention chemistry pretreating reagent is that the reasonable combination prescription through swelling agent, open chain agent and lubricant makes the big molecule of wool fully expanded; With the cross key of getting in touch between the wool macromolecular chain: spaces such as disulfide bond, salt type bond and hydrogen bond laterally are connected breaks; Fully reduce intermolecular internal stress; Make it possess the physical thinning ability; Under the effect of the wet heat condition of physical thinning wool equipment and tensile force, make common wool obtain abundant slenderizing again, through heat and chemical style-setting its drawing effect is for good and all kept getting off then.And can satisfy the requirement of the dyeing and finishing processing that goes on foot behind the wool fibre, make the boiling water retraction of fiber after its refinement reach the boiling water relaxation shrinkage index request of common wool.Its main mechanism of action is to reach desirable requirement through electronation and expanded.
The chemical pretreating reagent of the wool physical thinning of this programme is made up of swelling agent, open chain agent, lubricant and water, and its weight percentage is respectively: swelling agent 0.01～1.5%, open chain agent 1.5～18%, lubricant 0.1～5%, all the other are water.
Said swelling agent is a non-ionic surface active agent---AEO and NPE are a kind of.
Said open chain agent is a reductant---TGA and salt thereof, bisulfites, sulphite a kind of, this salt is their sylvite, sodium salt and ammonia salt.
Described lubricant is an amino-modified silicone oxygen alkane.
Have the organosilicon that profit turns usefulness into and mainly contain silicone oil emulsion and hydroxy-silicone-oil emulsion, in its host molecule structure, import amino, hydroxyl, epoxy radicals, polyether-based etc. and just formed modified organic silicon, importing amino just is called amino-modified silicone oxygen alkane.
Usefulness of the present invention is: the chemical pretreating reagent that adopts this programme; Can make the big molecule side group of wool fully expanded and break its intermolecular disulfide bond through reductant; Reduce the internal stress between the big molecule of wool rapidly; So that cooperate stretching wool equipment, can be under wet heat condition to twisted fibers or non-twist fiber realization mechanical stretching, can produce novel wool fibre with feel as gloss as the real silk, the cashmere.
(4) specific embodiment
Below in conjunction with embodiment the present invention is described further.
Embodiment 1:
Get sulfydryl with sour 3ml, NPE 0.1g, amino-modified silicone oxygen alkane 0.5g, add a certain amount of water and process the 100ml pretreatment liquid.
Choose 64 Australia's wool fibres and immerse in the above-mentioned pretreatment liquid, and on wool physical thinning testing machine, stretch, the refinement index before and after stretching is seen table 1.
Embodiment 2:
Getting sodium hydrogensulfite 5g, AEO 0.2g, amino-modified silicone oxygen alkane 0.5g adds a certain amount of water and processes the 100ml pretreatment liquid.
Choose 70 Australia's wool fibres and immerse in the above-mentioned pretreatment liquid, and on wool physical thinning testing machine, stretch, the refinement index before and after stretching is seen table 1.
Table 1: the technical indicator before and after the wool physical thinning
At present, the high branching of wool becomes the main flow of the market demand, and its reason is that the top grade of product, frivolous, personalized, soft, comfortable reaching are prone to nursing etc.And ramuscule (18～21 μ m), ultra-fine (15～18 μ m) wool are the bases of frivolous softness and comfortable no scratchy lining; Low or do not have felting property wool and high stability setting product be the lining easy care performance can assurance.Therefore, to the increasing demand increase of high-quality ramuscule and ultra-fine wool, and have big breach, tencel physical thinning wool fibre has satisfied the demand of ramuscule wool, has very big development space.
