摘要： A method for producing leather generally including the steps of: (a) providing wet blue, full grain skins, (b) applying a liquid chrome solution to the skins while at a pH of 3.5 or lower, (c) raising the pH level of the skins to at least approximately 6.0 or above, (d) retaining the skins with a vegetable tanning agent, (e) introducing the skins to a dye bath, (f) introducing lubricants into the dye bath, (g) fixing the dyestuff and lubricants in the skins while reducing the pH level to the range of 3.3-3.8, (g) introducing the skins to a second dye bath, (h) fixing the dyestuff while reducing the pH level to a range of 3.0-3.5, (i) introducing the skins to a float containing a waterproofing agent, (j) fixing the waterproofing agent while reducing the pH level to approximately 3.0, (k) capping the skins to remove emulsifiers, and (1) introducing the skins to a bath containing flame resistant agents.

摘要： The present invention relates to a suede-like sheet which is characterized in that, in a suede-like sheet comprising primarily ultrafine fiber of no more than 0.3 dtex and polyurethane, said polyurethane employs polymer diol containing 30 wt % to 90 wt % polycarbonate diol, said sheet contains from 20 wt % to 60 wt % of said polyurethane, the average nap length is 300 &mgr;m to 2000 &mgr;m, and the percentage retention of the local fatigue resistance before and after an accelerated ageing treatment is at least 50%, and it also relates to a method for the preparation of a suede-like sheet which is characterized in that, in the production of a suede-like sheet comprising a nonwoven fabric of ultrafine fibre of no more than 0.3 dtex and a polyurethane which employs polymer diol containing 30 wt % to 90 wt % polycarbonate diol, a buffing treatment is carried out after applying an antistatic agent to the sheet. By means of the present invention, it is possible to obtain a suede-like sheet which is ideal for clothing or as a seating fabric, where there is little exposure of polyurethane surface, which possesses an excellent nap which is elegant and outstanding in its evenness and, furthermore, which has a soft handle and even when employed over a prolonged period shows no lowering of strength or product quality such as rupture, fraying or pilling.
