1. The third step: stickness of sericin.

2. The complexity of the sericin composition has been affirmed.

3. The molecular conformation of silk sericin will be influenced by the mounting environments of cocoons.

4. The protein composition of sericin have been studied by polyacrylamide gel electrophoresis.

5. The sericin affinity to the hair and repairing the hair damaged had been researched systematically.

6. In addition, sericin can also repaired the hair damaged evidently.

7. Sericin, which has very wide applications, and is called to be " noble protein", consists of 18 kinds of amino acid.

8. The laser fluorescence spectrum of cocoon, and sericin of the major Chinese silkworm breeds and the variation regions of the spectrum parameters are presented first in this paper.

9. However, proper conditions can prevent sericin from gelation and improve cocoon reelability due to weaker gumming force among bayes.

10. There are relationships between the gumming property of sericin and the gelation.

11. The results show that diffluent sericin powder mainly offers random coil structure in its molecular conformation while high polymer amorphous structure of aggregating state.

12. The sericin globule was formed in Golgi complex of the middle silk gland cell and the sericin was released into the gland lumen by the similar way of fibroin fibers.

13. The results show that sericin could be directly coated on the oxidized cotton fiber without any other reagent and form a covalence bond between amido group and aldehyde group .

14. The different distilling methods freeze- method and dialyze- method of tussah and silkworm sericin were studied.

15. The structure changes of silk fiber with different weight gain, by using sericin fixing agent containing rare earth metal ion[Sentencedict], were studied in this paper.

16. Therefore, the improvement of cellulose fabric crease resistance by use of sericin is studied.

17. Ten different ways to cleaning polysulfone hollow fiber ultrafiltration membrane fouled by wastewater in sericin plants are studied.

18. The result showed that polyethylene glycol diglycidyl ether cross linked sericin obviously.

19. The chemical structure changes of the silk fibers after the sericin fixing with the sericin fixing agent containing rare earth metal ions were analyzed with FT-IR and laser Raman spectra.

20. The results showed that the soybean protein fiber properties modified by sericin and cationic agent were improved greatly.
