Problems solved by technology

[0002] At present, the fur tanning process consumes a lot of water. Generally, the weight ratio of water to animal skin, that is, the liquid ratio, is about 20. However, the chemical materials used in fur tanning are calculated according to the amount of water. Therefore, the large water consumption makes The use of chemical materials also increases accordingly, thereby increasing the amount of sewage, increasing the difficulty of sewage treatment, and causing greater environmental pollution; the increase in chemical materials and the increase in sewage treatment also increase processing costs

Abstract

The invention relates to the treatment field of animal furs and particularly relates to a method of preparing sheepskin clothing face garment leather with a small liquor ratio. The method comprises the following steps: pre-treating soil-species sheepskin in a paddle-tumbler, wherein the pretreatment includes the steps of soaking in water, washing the skin, re-soaking in water, shearing, removing meat and degassing, and a weight ratio of the water to the raw material kin in each pretreatment step is 9-11; then, performing pickling, depickling, re-pickling, tanning, re-tanning, neutralizing and oiling in a rotary drum in sequence, wherein a weight ratio of the water to the raw material skin in each treatment step is 5-7; and performing the processes of drying, moisture regaining, staking, dry cleaning, fine pruning, scalding, dry grinding and clearing to obtain the sheepskin clothing face garment leather. According to the method disclosed by the invention, the soil-species sheepskin is prepared into the sheepskin clothing face garment leather by adopting a small liquid ratio in the paddle-tumbler and the rotary drum, so that the water consumption in the process is reduced, the chemical materials are reduced correspondingly; and the finally prepared sheepskin clothing face garment leather is white in fur color, fine in dermatotome, full, soft and elastic in hand feeling and high in quality.
