re-soaking: adding water at normal temperature, Pasteur water-soaking enzyme S20 with concentration adjustable 0.1-1g/L, oil dispersant 0.1-1g/L for 30-60 min; discharging the skin, and enabling the skin plate to completely return water to a fresh skin state, and further carrying out secondary fleshing;
step six:
secondary fleshing: the meat remover can completely remove meat blocks and oil blocks on the skin plate and also has the function of squeezing and degreasing;
step seven:
softening, pickling and tanning are completed in one bath: controlling the water temperature at 36 ℃, adding 2-6 cc/l formic acid, adjusting the pH value to 3.2-4, adding 20-70g/1 salt, 1-7 g/1 Basff No. 1 tanning agent, 12-25 g/1 No. tanning agent, 0.2-2g/1 filling agent FS, 0-XFO.5-2 g/1 fatting agent E-IMO, 2-0.5 g/A, and running for 36-50 hours to get out of the machine;
step eight:
high-temperature shrinkage: developing and improving a drying room, directly putting tanned fur into the drying room without a nail plate for drying for 4-16 hours, and increasing the density;
step nine:
dry cleaning: adding tetrachloroethylene of 0.2-5g/l, washing for 12-36 min, and drying for 2-5 h;
step ten:
rewetting for 12-15 hours: the moisture content of the skin is consistent and reaches the required standard;
step eleven:
high-temperature degreasing: controlling the water temperature to be about 48 ℃, further removing grease, reducing the dosage of a dyeing auxiliary agent, effectively protecting the gross phosphorus sheet from being damaged, adding a degreasing agent, namely 0.3-1 g/1 of high sand upper, 0.2-0.9 g/l of grease dispersant, and lasting for 30-45 minutes;
step twelve:
primary ironing and shearing: the method comprises the following steps of scalding at the temperature of 100-160 ℃ of a scalding machine, then primarily shearing to the required length, brushing first scalding liquid (uniformly mixed according to the proportion of 500 ml of water, 200-300 ml of formic acid and 100-300 ml of alcohol), uniformly brushing, standing for 15 minutes, adjusting the temperature of the scalding machine to 160-180 ℃, then scalding, and then shearing by a fine shearing machine;
step thirteen:
dyeing: dyeing according to the requirements;
fourteen steps:
secondary ironing and shearing: preparing a second perming liquid (500 ml of water and 200-500 ml of perming agent NF are uniformly mixed), uniformly brushing, standing for 10-40 minutes, adjusting the temperature of the perming machine to 100-200 ℃, performing primary perming again, and then shearing.
2. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the second step, the basf soaking enzyme S20 is mainly used for removing stains on the surface of the cashmere and decomposing the cashmere fibers to enable water to easily enter the collagen fibers, so that the purpose of soaking is achieved.
3. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the fourth step, the degreasing agent Youzanbang OC is a nonionic surfactant and has excellent emulsifying property and wetting property.
4. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the third step and the sixth step, a cleaning mechanism and a scraping mechanism are arranged on the fleshing machine so as to clean the fleshing machine.
5. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the seventh step, the whitening agent can convert the invisible ultraviolet radiation absorbed into the violet fluorescent radiation, and the violet fluorescent radiation and the original yellow fluorescent radiation are complementary to each other to form white light, so that the whiteness of the product under sunlight is improved; the fat-liquoring agent has strong self-emulsifying capacity and good emulsion stability, and is beneficial to the combination of grease.
6. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the step eight, the drying room comprises a support and a drying device, the fur is hung on the support, the support can move, the moving speed is adjustable, hot air forms circulation, and the drying temperature is adjustable.
7. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the ninth step, the drying temperature of the dryer is 50-90 ℃.
8. The production and processing technology of high-density cashmere according to claim 1, characterized in that: in the twelfth step, a brush roller is arranged on the natural luster finishing machine, and the brush roller and the natural luster finishing machine body are detachably arranged.
