Liming enzyme for sheepskin
Chemical & Physical Properties:
DOWELLZYM LS is a liming enzyme especially for sheep and goat skins. It improves the efficiency of liming and re-liming processes; and has following advantages:
1.Open collagen bundles of polysaccharide, make protein fiber fully loose and scattered resulting soft and full leather.
2.Effectively Loosen hair root, epidermis, natural pigments; clean the skin surface, remove/reduce the wrinkles and growth marks, noticeably change the grain structure, improve the area yield.
3.Effectively increase lime solubility and suspension stability, which shortens the liming time, promote uniformity of liming.
4.It is possible to reduce the dosage of sulfide, lime and other related auxiliaries used in liming process by using DOWELLZYM LS.
5.Using DOWELLZYM LS together with DOWELLZYM S2 (in soaking) and DOWELLZYM OS (in bating) are recommended for lime-free clean technology process of sheep skin. There is no need to pickle the skins or use solvents such as kerosene in degrease process to achieving low fat content. It is possible to eliminate use of lime completely, shorten the processing time, and improve the tear strength of leather by using DOWELLZYM LS.
6.DOWELLZYM S2 combined with DOWELLZYM LS and DOWELLZYM OS will help to achieve low carbon foot print requirement in lime-free clean technology process.
1.DOWELLZYM LS is mainly used in liming and re-liming process of sheep and goat skins. It can be used on its own for sheep skins. Using DOWELLZYM LS together with NOWOLASE XL (in alkali pasting for the back born area) gives much more even liming effect.
2.DOWELLZYM LS reduces neck wrinkles and growth marks, helps to maintain regular-shape pelts of Goat & Sheep skins after liming.
3.DOWELLZYM LS can be directly added without diluting with water. It is suggested add DOWELLZYM LS after alkali sulfide and lime running for 1-3hours and run for 30-60 min to make sure that DOWELLZYM LS distributed completely in the float and on timer run O/N.
1. Sheep skin after lime painting (Concentration above 120 g/L Na2S) and unhairing.

2. Goat skin after painting (Na2S with 0.5% NOWOLASE XL) and unhairing.

Enzyme is a kind of protein, contact may cause anaphylactic reaction; avoid breathing dust and contact with skin. If splashed into eyes，immediately wash with plenty of water.
