[0042] Figure 1 to Figure 10 Examples are shown. figure 1 It shows the process of manufacturing a protein processed fiber, for example, bleaching or dyeing the fiber which is a precursor (precursor fiber) with the dyeing machine 2 before providing the surface layer of protein. Next, in the adsorption tank 4, the precursor fibers are immersed in an aqueous solution of hydrolyzed products of animal proteins such as keratin, fibroin, and sericin, or in an aqueous solution of artificial or synthetic proteins. The surface forms the surface layer of these proteins. It should be noted that the shrinkage rate of the parent fiber and the surface layer of the protein are different in hot water.
[0043] The fiber with the surface layer formed is processed in the crack forming tank 8 to form cracks in the surface layer made of protein. When the fiber passes through the hot water in the crack forming groove 8, the precursor fiber shrinks in the longitudinal direction and expands in th...
manufacture example
[0062] When feathers are used as raw materials, the alkaline concentration in the bath is set to 0.2-0.8 mol / L, and the treatment is carried out in the range of 20-120°C for 0.1-16 hours. Separation removes insoluble components. Next, an aqueous solution of hydroxypropyltrimethylammonium chloride (Hidrokis Propil Trimethlium Chloride) was added to the aqueous protein hydrolysis solution to adhere to keratin. In addition, 0.001 to 20% by mass of hydroxypropyltrimethylammonium ion is added per 100% by mass of keratin. Moreover, it measured by the gel filtration method, and the average molecular weight of keratin was 10000-11000.
[0063] The feather-derived keratin aqueous solution concentration was adjusted to 20% by mass, put into the adsorption tank 4, and the liquid temperature was maintained at 37°C. After removing the sericin, the monofilament-like silk fibers were dipped for 5 minutes to form a keratin surface layer. In addition, it has been confirmed through prelimina...
Embodiment 2
[0069] Figure 11 The method for producing the surface-processed fiber in Example 2 is shown, except for the points specified, the same as figure 1 The embodiment is the same. If necessary, the refined silk is dyed in the dyeing step 51 . Next, in the adsorption process 52, the surface layer is formed by immersing in a warm aqueous solution of feather-derived keratin. Then, in the drying step 53 , hot air drying is performed, for example, under conditions such that the moisture content of the silk is 9% by mass or less, preferably 5% by mass or less. The fiber is stretched in the stretching step 54 while maintaining the dry condition, and the tension is released in the tension releasing step 55 .
[0070] In the adsorption step 52, for example, silk that has been previously stretched 6% in the longitudinal direction is immersed in a 10% by mass aqueous solution of feather-derived keratin having a liquid temperature of 60°C and an average molecular weight of 1500 for 5 minut...
