- Raw hides are usually salted or dried to prevent rot.
- Rinsing is usually carried out for 48 to 96 hours, preferably about 72 hours, using paddles, drums, wattles, and the like.
- a surfactant, a preservative, or the like may be used.
- the pH at the time of washing is usually 7 to 8.
- the raw hide is dipped in lime milk, the skin is swollen with alkali to loosen the collagen fibers of the hide, and the hair, fat, and epidermis layer are decomposed and removed (lime pickling or liming).
- the machines used are paddles and drums.
- the chemical used is calcium hydroxide.
- sodium sulfate, sodium hydroxide and the like may be used in combination.
- a dedicated surfactant may be used.
- the pH of lime pickling is usually pH 12 to 13, and the amount of calcium hydroxide and the like added is adjusted to this pH.
- the processing time is usually 72 to 120 hours, preferably about 96 hours. After this lime pickling, it is preferable to wash with water.
- bleaching is performed using a bleaching agent.
- the bleaching agent include sodium sulphite, sodium hyposulphite, hydrogen peroxide and the like. Among them, it is preferable to use sodium sulphite.
- the amount of the bleach used is appropriately adjusted depending on the type and amount of the skin, and, for example, 2 to 15 parts by mass of sodium sulfite, preferably 2 to 15 parts by mass of sodium sulfite per 100 parts by mass of the skin The range is 5 parts by mass.
- the processing time is usually 24 to 120 hours, preferably about 48 hours.
- the machines used include, for example, paddles and drums.
- the pH of the hide is adjusted, for example, to a range of pH 6 to 8, preferably pH 7.
- Chemicals used for pH adjustment include, for example, sulfuric acid, hydrochloric acid, and lactic acid. After this pH adjustment, the skin is again washed with water to prepare a raw hide.
- the raw hide is roughly cut. Its size is, for example, 2-5cm square, preferred About 3 cm square.
- machines used for rough cutting include a hood power cutter and a chopper.
- the coarsely cut raw leather is put on a chopper, and further cut into micro cuts.
- the diameter of the chopper is, for example, 30 to: L5Omm, and preferably 10 Omm.
- collagen fibers can be prepared.
- the raw skin may be decomposed by using an enzyme to prepare collagen fibers. Examples of the enzyme include collagenase.
- a binder and water are blended with the collagen fiber and mixed with stirring to prepare a sol-like or gel-like collagen fiber.
- the binder preferably uses collagen fiber powder and gelatin, but it is also possible to use other binders.
- Collagen fiber powder can be prepared by yourself.
- the collagen fibers may be dried to powder, or the collagen fibers may be powdered and dried.
- the collagen fiber powder does not need to be in a dry state.
- the mixing ratio of the collagen fiber powder is, for example, 5 to 50 parts by mass, and preferably 30 parts by mass with respect to 100 parts by mass of the collagen fiber.
