Abstract
The chemical treating agent for fining and stretching wool is water solution containing reductant for breaking sulfur bond 2-30 wt%, wetting agent 0.05-2 wt%, swelling agent 0-5 wt% and high-valent metal ion shielding agent 0-1 wt%. It has the effect of resulting in high wool stretching amount and less damage to wool.
Description
The present invention is a kind of chemical treatments that stretching wool is used that belongs to
As everyone knows, wool is a kind of important textile raw material, and it has good springiness, and hygroscopicity is strong, and warmth retention property is good, is difficult for staining the soft good characteristic that waits of gloss.These performances make wool fabric have purposes widely.High-grade wool spinning fabric need be produced with the ramuscule wool, the costing an arm and a leg of ramuscule wool, and reduce with wool fiber diameter, its price increases.Especially below 20 μ, the price ascensional range is bigger.For reducing the production cost of high-grade wool spinning fabric, research (long Ze Zefu, dyeing industry (day) Vol.47, No7, the p336-342 of stretching wool refinement appearred; US 5697983; US5477669; JP10-158976).
Wool is made up of by the protein macromolecule that amido link couples together several amino acids.Have in this macromolecular chain and contain two carboxyls, (S-S-) cystine of key, a pair of amino and carboxyl in a macromolecular chain, just have disulfide bond to couple together between such two strands respectively for two amino and one two sulphur.Within these macromolecular chains, also have the aspartic acid of two carboxyls, form acid side group; The lysine that two amino are arranged forms alkaline side group.It is crosslinked that the bronsted lowry acids and bases bronsted lowry side group forms sat linkage.In addition, because protein molecule is by a large amount of amido links amino acid to be coupled together, the amido link between the different molecular chain also can generate a large amount of hydrogen bonds.Can represent with the crosslinked schematic diagram between the following wool macromolecular chain visually that these keys also are present in big intramolecule (textile material is learned, p114, China Textiles Press, volumes such as Mu Yao) simultaneously:
For the ease of stretching, need open the disulfide bond between these molecules.Disulfide bond between protein molecule can have many methods to open: as the method with hydrolysis, decompose with the alkali of high concentration, with oxidant such as hydrogen peroxide, hypochlorous acid, perchloric acid oxidation's method and with the method for thioglycolate salt, sulphite, this class reductant of bisulfites.With the method for hydrolysis, reaction speed is extremely slow, no practical value; Make its decomposition lose sulphur with high concentration alkali chain rupture meeting, can form complicated structure with the method for oxidation, typing is difficult causing after; Method disconnection disulfide bond with reduction is proper.Single have the fiber wettability poor with above-mentioned reductant processing wool fibre, and bulk degree is low, and a small amount of high volence metal ion in the while water at once will be crosslinked hydrogen sulphur (mercapto) base that the disulfide bond that is reduced forms.By high-valency metal crosslinked-the S-Me-S-key not only hinders stretching, even and these keys in drawing process, broken, can't recover again in the type-approval process afterwards.So people still study the chemical treatments that new stretching wool is used constantly.
The purpose of this invention is to provide the chemical treatments that a kind of stretching wool is used.
In the chemical treatments that stretching wool of the present invention is used, not only contain the reductant that disconnects disulfide bond, also adding wetting agent can make fiber surface wetting, make the structure pineization of wool with leavening agent, use simultaneously the high volence metal ion screener mask high volence metal ion make its can not with the wool molecule in be reduced out-the SH base is crosslinked in drawing process.
The chemical treatments that stretching wool of the present invention is used is to add wetting agent, swelling agent, high volence metal ion screener again in the reductant aqueous solution of disulfide bond disconnection usefulness.
Concrete composition of the chemical treatments that stretching wool of the present invention is used and weight percentage are as follows: disconnect disulfide bond reduction agent 2-30%, and wetting agent 0.05-2%, swelling agent 0-5%, high volence metal ion screener 0-1%, all the other are water.
The disconnected reductant of disconnection disulfide bond of the present invention can be the reductant of sulphite, bisulfites, thioglycolate salt, and its salt can be their sylvite, sodium salt or ammonium salt.
