Description
Technical field
The present invention relates to fur process field, specifically the low consumed fur tanning method of a kind of short route.
Background technology
The idiographic flow of traditional fur tanning method is as follows: pre-immersion → main immersion → fleshing → degreasing → washing → enzyme bating → pickling → tanning, exists following subject matter:
1) have 8 operations at least, operation is loaded down with trivial details; In about 4 days cycles of whole technique, the production cycle is long; Account for current assets large.
2) water consumption is large.
Because fur has abundant fleece, in order to prevent adding hair fibre entanglement in man-hour or bonding, the water consumption of pre-immersion, main immersion, degreasing, washing, enzyme bating, pickling and tanning processes is all 15 ~ 20 times of cortex amount, to process 100KG raw material skin for benchmark, water consumption is as follows: (100 × 15 ~ 20) × 6 ~ 7 water conservancy project sequence=9000 ~ 14000KG.
3) chemical materials consumption is large, and cost is high, and processing waste water is big for environment pollution.
1. in order to protect, soft, plentiful, the extensibility of positive fur product dermatotome is large, to go out sanction rate high, and does not fall hair, adopts that acidicenzym softens, pickling, with loose dermatotome collegen filament in process.
2. acidicenzym softens needs to add a large amount of acid materials with pickling, such as sulfuric acid, formic acid, acetic acid, citric acid, lactic acid etc., violent expansion (being commonly called as sour swollen, acid plumping) can be there is in acid condition in dermatotome, and dermatotome can not carry out next step tanning in the expanded state, dermatotome is suppressed to expand in acid condition so need to add in, pickling softening at acidicenzym and this three process of chrome tanning system a large amount of Industrial Salt (more than 60g/L or 6 degree Beaume more than) on producing.To process 100KG raw material skin for benchmark, Industrial Salt consumption is as follows: (100 × 15 ~ 20) × 2 × 60=180 ~ 240kg.
3. middle and high concentration Industrial Salt possibility inhibitory enzyme agent activity is softened at acidicenzym, so zymin consumption can be made to strengthen, softening and pickling time lengthening.
4. a large amount of Industrial Salt makes chrome tanning agent specific absorption and tanning effect decline, and cause chrome tanning agent consumption to increase, add chromium content and neutral salt content in waste water simultaneously, cost increases, and also environmental pollution increases.
4) fur fleece is loose not flexibly, clean not.Because fur is softening through acidicenzym, after pickling, significant quantities of fat, fibrous matrix proteins enter in waste liquid, because dermatotome is acidic conditions, therefore can not wash with clear water (can be serious sour swollen with clear water washing dermatotome), be not easy to remove the fat, the fibrous matrix proteins matter degraded product that enter in waste water in time, thus the fur fleece of tanning is flexibly loose not, clean not.If washed after, pickling softening at acidicenzym, just must add the Industrial Salt of more than 60g/L in clear water, suppress dermatotome acid plumping, and this increases consumption to Industrial Salt and environmental pollution.
5) select during zymin and have certain blindness, not strong to different components targeting in dermatotome, produce difficult control, easily cause softening not in place or excessively softening, pelage quality is unstable.
