Problems solved by technology

First of all, the cost of rare earth is high, and the waste water generated in the production process is also difficult to deal with
In addition, sericin fixation can only increase the weight of silk fibers but cannot modify them, so it is still insufficient.
[0007] In a word, the processing methods of these weight-increasing real silk fibers mentioned above all have certain shortcomings, especially the pollution impact on the environment is relatively large, and it is difficult to realize industrial production at present.

Abstract

The invention discloses a method for plasma graft weight gaining of real silk fabric, and belongs to the technical field of functional arranging of fabric. The method comprises the steps of real silk fabric preparing, refining processing, expansion processing, graft liquid adsorbing, loose drying, plasma graft polymerization weight gaining, soap boiling processing, washing, stoving and arranging. Prepolymerized graft monomers with certain molecular weight are utilized to be adsorbed on to-be-grafted fabric firstly, and then led into the inner surface and the outer surface of the real silk fabric; then the real silk fabric is led into plasma graft equipment to be carried out graft weight gaining polymerization reaction; industrialized production can be carried out; the graft liquid can be repeatedly used; the method has the advantages that the effect is good, the technology is simple, the energy is conserved, the efficiency is high, and the cleaning production and the environmental protection are facilitated; the graft degree is just right on the basis that the original style of the real silk fabric is not influenced; thick and elastic effects of lighter real silk fabric are realized; the purpose of improving wearability of the real silk fabric is achieved.

Description

【Technical field】 [0001] The technical field of the invention is the functional finishing of fabrics, and in particular relates to a method for grafting and weighting real silk fabrics by using plasma technology. 【Background technique】 [0002] Silk fabric has bright luster, smooth and soft touch, and is a high-grade textile fabric. Silk fiber is mainly composed of two proteins, silk fibroin and sericin, among which sericin accounts for about 25% of the total weight of silk fiber. The middle of each single filament is silk fibroin, and the outside is sericin. Sericin molecules are irregularly arranged in an amorphous structure, and the closer to the silk part, the more obvious its crystallinity, but the crystal part is much smaller than the silk part. Therefore, silk fibroin is more polar and water-soluble than sericin. For a long time, the dyeing process of real silk has been to remove the sericin first, and remove the sericin on the surface of the silk fiber through scou...
