With the use of modern distension elements / pelt boards (6) consisting of two half-parts with surfaces (14) with open structure (18) in connection with the drying of pelts (26), where the pelt is secured in the stretched position during the drying procedure by means of a holding bag (28) which, in an area at the tail end of the pelt, presses the pelt against a special holding area (8) on the surface of the distension element / pelt board, there can appear areas of the pelt where this has not been sufficiently dried, and where the pelt therefore turns mouldy / decays. Moreover, as a consequence of the pelt slipping on the surface of the board, it can be difficult to obtain a straight measuring line for the measurement of the length of the pelt. In order to relieve these problems, there is disclosed a sleeve / pelt bag item of fat and moisture absorbing material which is characteristic in that the pelt bag (10) consists of a tubular bag item to be drawn over the outside of the distension element / pelt board from the pointed end of the board for the covering of at least a part of the holding area on the distension element, the extent of said pelt bag corresponding at least to 1 / 3 but preferably1 / 2 of the extent of the holding area (8) on the distension element (6).

The invention relates to the leatherworking field, and specifically relates to a printing and color developing method of fur. The method comprises the following steps of: a) material choosing: choosing a fur material according to requirements; b) pretreatment: subjecting the chosen fur material to retanning treatment; c): fine treatment: straightening the hairs on the retanned fur material, and trimming as well as flattening the hairs; d): pattern printing: coating a printing solution on the hairs according to a needed pattern design; and e) dyeing: dyeing the printed fur material. The printing and color developing method of fur in the invention reduces the realization of a bicolor effect of single hair from two-step dyeing in traditional making processes to just one-step dyeing, thus reducing making steps and lowering the complexity degree of the making method. Based on the dye adsorption ability of a printing and color developing agent, the method in the invention depends on the difference between the dye adsorption degrees of a part coated with the printing and color developing agent and a part not coated by the color developing agent to realize the bicolor effect of single hair. Transition between the two dyed colors is more natural, and the effect is better than that of traditional methods.
