Description
Technical field
The present invention relates to a kind of processing method of the cocoon fiber that increases weight, particularly a kind of adhering sericin realize increasing weight processing method of cocoon fiber that adopts.
Background technology
Silk fiber has bright gloss, the feel of smooth, soft, and moisture pick-up properties and slim and graceful outward appearance etc. are a kind of weaving face fabrics of top grade preferably, have the title of " fiber queen ".Silk fiber mainly is made up of fibroin and two kinds of protein of silk gum, and wherein silk gum accounts for 25% of silk fiber total weight, and every silk is to be bonded by silk gum abreast by two monofilament, and the centre of every monofilament is a fibroin, and the outside is a silk gum.The silk gum molecule is the non-crystal structure of irregular alignment, and more near the fibroin part, its crystallinity is more obvious, but its crystalline portion is much smaller than the fibroin part.Therefore fibroin is compared with silk gum, and it is big, water-soluble also big that the latter's polarity is wanted; Silk gum is translucent colloid, and energy is water-soluble, the aqueous solution of bronsted lowry acids and bases bronsted lowry, and the solubility of silk gum in water depends on temperature, time, pH value and electrolytical existence.For a long time, the dyeing processing of silk broadcloth fiber all is to adopt traditional processing mode, in order to remove silk gum, concise operation is absolutely necessary, by the concise silk gum of sloughing the cocoon fiber surface, like this, the weight saving of silk fiber about 25%, fiber attenuates, and makes real silk fabric exist defectives such as wear-resisting wiping is poor, crease recovery is poor, wash and wear difference.Therefore, the weightening finish cocoon fiber is one of effective way of improving the silk fiber wearability.
The processing method of weightening finish cocoon fiber mainly contains following two classes: a class is to carry out chemical modification on fibroin fiber, and to reach the weight that increases fiber, main processing method has: (1) uses pink salt metalloid ion processing cocoon fiber; (2) on fiber, introduce the polyvinyl copolymer with vinyl monomer by the initiation of initator.Another kind of is the method for adhering sericin, by the polar group on sealing or the interlinkage silk gum fiber, increases the processing method of silk fiber weight to reach adhering sericin, and the chemical reagent of main effect has: the derivative of (1) aldehyde or aldehyde; (2) heavy metal salt; (3) tannin (tannic acid) class; (4) synthetic resin.
Method with pink salt metalloid ion weightening finish silk fiber is to place squeeze tin chloride solution neutralising phosphoric acid sodium solution (phosphatization) alternately to soak, each silk fiber after treatment all will wash and acidifying, after repeatedly processing makes silk fiber be increased to enough weights, handle with sodium silicate solution at last.Complicated with this method processing technology, and final products largely depend on the specific condition of processing; Also because the silk fiber surface after the pink salt processed is to exist with silicic acid tin colloid form, the trend that becomes the lenticular form is arranged, this makes silk fiber be subjected to a certain degree destruction, when excessive weightening finish, when particularly having trace salt and ion to exist, capital damage fiber, therefore, the fastness of silk fiber, durability are subjected to very big influence.
Form the method for graft copolymer with silk fiber (fibroin) with vinyl monomer under the initiation of initator, monomer whose mainly contains hydrophobic monomer and hydrophilic monomer two big classes.As styrene, acrylic acid, methacrylic acid, methyl methacrylate, ethyl methacrylate, butyl methacrylate, glytidyl methacrylate, hydroxyethyl methylacrylate etc.The uniformity that can form a large amount of Lustrexs and graft copolymerization when its major defect is graft copolymerization of vinyl monomer is relatively poor, the existence of homopolymers and the inhomogeneities of graft copolymerization are disadvantageous to the dyeability of fiber, spend as the dyefastness and the generation dyeing look that reduce fiber etc.; Aberration after the randomness of graft copolymerization causes dyeing is bigger.Therefore how removing Lustrex effectively and improve graft copolymer distributing homogeneity on fiber in suitability for industrialized production is two big difficult points of this class processing method, does not up to the present also find effective solution.
With the method for the silk gum set cocoon fiber that increases weight, it also is a noticeable research topic, it is imagined substantially: reduce the water-soluble of silk gum by crosslinked sex change, make it become the lasting part that keeps of silk surface energy, make full use of silk gum, weightening finish cocoon fiber to reach, and save or shorten Degumming Procedures, reduce the purpose of fibroin damage.Before the present invention makes, publication number is a method of having described usefulness triazine skeleton cross-linking reaction adhering sericin during the patent of invention of CN1262713A " utilizes the fixing yarn of silk gum to make the method for woven or knit goods and the woven or knit goods made of method thus ", and used finishing agent is the REACTIVE DYES of cyanurate and derivative or trimerization piperazine acid derivative; Publication number is to have described with glutaraldehyde or Cyanuric Chloride sticking agent in the patent of invention " a kind of processing technology of short-fibre silk of cocoon garment " of CN1024931C to come set husks or its fabric, with the example with glutaraldehyde is: husks or fabric 25 ℃ or 40 ℃ down with 0.3% glutaraldehyde and 0.5% rare earth in pH=3.0 ~ 4.0 or 9.0 ~ 9.5 times processing regular hours.Example with Cyanuric Chloride is: husks or its fabric are handled the regular hour with 5% Cyanuric Chloride down at 25 ℃ under pH=9.
In the technique scheme,, volatility is arranged because employed Cyanuric Chloride is unstable in air, very easily moisture absorption, and can and reduce its reactivity with the direct reaction of water, and higher during actual production to environmental requirement, therefore, be difficult to adapt to the requirement of printing and dyeing processing.And the shortcoming of the REACTIVE DYES adhering sericin of cyanuric chloride derivant is: when removing not set or the unstable silk gum of set, REACTIVE DYES can split away off from fiber because of hydrolysis, has both wasted dyestuff, has increased the weight of sewage load again.In a word, the processing method of these weightening finish cocoon fibers all exists certain shortcoming, and especially the pollution effect to environment is bigger, is difficult to realize suitability for industrialized production at present.
