Description
Technical Field
The invention relates to the field of mulberry silk processing technology, in particular to a silk glue-retaining technology and high-sericin silk.
Background
The silk mainly comprises silk fibroin and silk gelatin, wherein the silk gelatin is coated on the periphery of the silk fibroin, and accounts for about 20-30% of the mass of the silk fibroin, and the silk gelatin and the silk fibroin comprise 18 amino acids and contain about 97% of pure protein. The fiber obtained by silk finishing process belongs to a high-grade fabric raw material, and the chemical and physical properties of the fiber material directly influence the comfort and the handfeel of the fabric, the dyeing uniformity and other performances, so the functional treatment finishing of silk fiber is always a field of important attention in silk industry.
The sericin layer in silk is easy to swell, crack and hydrolyze protein fiber in weak acid and weak alkali water solution, and the silk swells and dries when contacting water, and has the problem of hardening. In the traditional silk dyeing and finishing process, sericin is usually removed, and only a soft and elastic silk fibroin part is utilized, so that sericin resource waste and environmental pollution are caused. Therefore, it is important to fix the sericin on the surface of the silk fibroin for retention.
In recent years, research, popularization and application of the sericin adhesion technology not only solve the problem to a certain extent, but also endow the silk with the functional characteristics of plumpness, thickness, stiffness, and the like. At present, the research on the sericin finishing agent at home and abroad mainly comprises types of chromium salt, small molecular aldehyde, tannic acid, synthetic resin, active chlorine-containing s-triazine compounds, epoxy compounds and the like, and the sericin finishing agent has various varieties, but has advantages and disadvantages to a certain extent due to different performances.
The chromium salt gel curing effect is excellent, but the chromium salt gel curing effect has color, trivalent chromium salt is easily oxidized into hexavalent chromium salt with carcinogenicity under the conditions of high temperature and high pH value, and the trivalent chromium salt is hardly used for gel curing treatment.
Formaldehyde is the traditional method in the early development stage of the solid glue, has good effect, is extremely volatile, has carcinogenicity and is unfavorable for human health, and along with the requirements of ecological environment-friendly silk fabrics, formaldehyde gradually exits from the application process of the solid glue. Glutaraldehyde, although having good gum fixing effect (good protein crosslinking effect), is easy to yellow, is unfavorable for processing white and light silk, can only be used for gum fixing treatment of dark silk products, and greatly limits the application range of glutaraldehyde gum fixing.
Tannic acid lacks a certain amount of firm covalent bonding mode for silk protein chemical crosslinking, the crosslinking and glue fixing effects are weak, the tannic acid has darker color, silk is dyed with the tannic acid, the staining performance of the silk is greatly affected, and the method is rarely adopted.
Zhou Hongxiang et al report that three epoxy compounds are used for silk sericin adhesion finishing, but the three compounds are used in silk finishing process, a catalyst KSCN (toxic substance) needs to be added, the three substances are required to be subjected to glue fixing in an organic solvent such as isopropanol, and unreacted epoxide on silk needs to be washed by a solvent such as acetone after treatment, and the method is limited to laboratory theoretical research.
The treatment process fixes the sericin, but has limited alkali resistance improvement and does not meet the formaldehyde content standard requirement, and the low-temperature silk reeling and low-temperature dyeing and finishing processes try to retain the sericin, but the essential problems are not solved, the product is troublesome to use and maintain, and the application range is limited.

4. Softness and color
According to the factory cargo checking flow, a factory cargo inspector manually observes and evaluates the hand feeling softness of the silk fabric through hand touch.
The test method is as follows:
the inspection staff has inspection experience for more than 2 years, and the silk fabric is rated.
Each inspection person randomly performs spot check on each roll of silk fabric for 10 times, each spot check takes the area of 30 multiplied by 30cm as the unit spot check area, the hand feeling softness and the color of a test sample are evaluated, 2 inspection persons evaluate the test sample according to the evaluation method, the scoring results are averaged, the results are shown in table 3, and the scoring standards are as follows:
1 part, the soft hand feeling and the color are obviously inferior to those of the original silk fabric, the obvious difference influencing sales is caused, and the fabric cannot be sold after being reduced.
1-2 Minutes (excluding 2), the silk fabric is soft in hand feeling and color, and can be sold after being degraded.
The fabric is 2-3 minutes (excluding 3), has soft hand feeling and color slightly inferior to those of the original silk fabric, but does not need to be reduced.
3-4 Minutes, the soft hand feeling and the color are slightly different from those of the original silk fabric, and the reduction is not needed.

According to the application, the high sericin silk is treated by the treatment liquid, the treatment liquid is prepared by adopting the compatibility of the aqueous acrylic resin, the guanidine salt and the silane modified polyurethane, and the dosage of the aqueous acrylic resin, the guanidine salt and the silane modified polyurethane is further optimized, so that the obtained silk retains higher sericin, and meanwhile, the obtained silk and silk fabric have higher mechanical property, softness, dyeing glossiness and uniform dyeing property, and the obtained silk and silk fabric have excellent comprehensive properties.
As shown in the data of the different examples in table 3, when the effect of retaining the adhesive is good, the adhesive force between the threads is enhanced, so that the threads are less likely to slip. In this case, the combing data of the fabric will be reduced, i.e. the combing resistance will be enhanced. In addition, the silk fabric loses the original color and luster and becomes soft when the sericin is stripped off. The hand feel is hardened without the retention of the sericin, and the score is higher when the sericin is retained and soft hand feel is maintained after the retention of the sericin, so that the embodiments 1,3,5, 6 and 7 have relatively good retention effects, and more preferably the embodiments 1,3,5 and 6.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
