Soft upper leather of sheep production process control of water in field

Fatliquor fatliquor these 2 can give the leather surface silky comfort. Tan Lihua C3% weakly cationic polyurethane retanning agent, NE to be self-emulsifying of neat's foot oil fatliquor, both used in conjunction, can effectively increase the vegetable tanned leather billet strength. In general, the vegetable tanned crust without a heavy finish, so I added fat is critical processes, required by the leather surface wax feeling,[link widoczny dla zalogowanych], color effects and the choice of Fatliquor close. If the leather also requires a certain waterproof, washable performance fatliquor formula should have the right amount of washable,[link widoczny dla zalogowanych], waterproof 3111. If you do wax polish varieties, but also to join with wax or other special effects become additive. 2.10 The dry slowly help to improve flexibility of finished leather dry vegetable tanned crust generally accomplished through natural hang to dry,[link widoczny dla zalogowanych], should be appropriate to slow the rate of drying,[link widoczny dla zalogowanych], drying too quickly will affect the feel of leather and softness. Under normal circumstances, after thorough drying, wet milling is finished return; if required wax leather has a strong sense, even after milling through a high temperature of the hot skin in order to meet the requirements; leather lighter if required, After the fall of soft leather billet needs polishing; also be used dry vacuum methods to improve the smoothness of grain and luster. 3 Conclusion vegetable tanned leather and the traditional clothing of sheep positive fashion leather vary greatly, and general style of garment leather of sheep compared to grain crust requires more stepped up to implement some, very real body bone to the appropriate point, extension can not be too large.

This paper is the result of several process tests, plus T on some technical points are summarized and analyzed. Because different customers require different products, the corresponding processing methods are also different. For some specific technical problems, needs further discussion.
