    摘要： The invention relates to the technical field of animal fur processing, and particularly relates to a cutting and double-face leather integrated dyeing process for Tan sheep skin, which comprises the following steps: cutting→washing with water→retanning→primary dyeing→primary colour fixing→secondary dyeing→fatliquoring→secondary colour fixing→bleaching→drying→a finished product. In the process of the invention, the third-grade Tan sheep skin which does not reach a superior quality is selected and subjected to cutting treatment and then double-face leather integrated dyeing; after the dyeing has been completed, the leather board has softness, good fullness and elongation, substantially uniform thickness, and no phenomena such as stiff board and swelling board occur; the fleece is smooth, flexible and loose and clean with complete needle velvet, and no phenomena such as serious fur shedding, oily fur and fur twisting occur. Tan sheep skin leather boards and fleeces dyed by the process of the invention have no cross colour and colour fading with each other, a high colour fastness, and uniform dyeing; the prepared Tan sheep skin products such as clothing, etc., not only have the characteristics of a high added value and good practicability, but also can more largely increase product benefits and lower the production cost.

    摘要翻译： 本发明涉及动物毛皮加工的技术领域，特别涉及一种用于谭羊皮的切割和双面皮革综合染色方法，其包括以下步骤：切割→用水洗涤→复鞣→初级染色→原色 固色→二次染色→加脂→二次染色→漂白→干燥→成品。 在本发明的过程中，选择不具有优良品质的三级谭羊皮，进行切割处理，然后进行双面皮革一体染色; 在染色完成后，皮革板具有柔软度，丰满度和伸长率，厚度基本均匀，并且不会发生刚性板和膨胀板等现象; 绒毛光滑，柔软松散，整齐的针织天鹅绒，没有发生严重毛皮脱落，油性毛皮和毛皮扭曲等现象。 通过本发明方法染色的谭羊皮皮板和绒毛彼此没有交叉颜色和褪色，色牢度高，染色均匀; 制作的谭羊皮等产品，如服装等，不仅具有附加值高，实用性好的特点，更能大幅度提高产品效益，降低生产成本。
