A kind of printed top layer leather and its processing technology

Abstract

The invention discloses a processing technology of embossing top layer leather. The embossing top layer leather is made through the steps of depilating, degreasing, liming, deliming, tanning, fat liquoring, drying, staking, finishing and embossing; in the embossing step, the top layer leather is subjected to printing through an embossing machine; the embossing machine comprises an embossing frame,a flattening device, an embossing device and a cooling roller, and the flattening device, the embossing device and the cooling roller are sequentially arranged on the embossing frame according to theprocessing sequence; the flattening device comprises a heating plate, a flattening piece and a plurality of compressed springs; the multiple compressed springs are vertically and uniformly distributed on the embossing frame, one ends of the compressed springs are connected with the embossing frame, and the other ends of the compressed springs are connected with the lower surfaces of the heating plate; the flattening piece is used for flattening and pushing the top layer leather; the embossing device embosses the top layer leather after flattening; and the embossed top layer leather is cooledthrough the cooling roller. Compared with the prior art, the embossing effect and the embossing efficiency of the processing technology are greatly improved.

Description

technical field [0001] The invention relates to the field of leather, in particular to a printed top layer leather and a processing technology thereof. Background technique [0002] Printed top layer leather is embossed or printed on the top layer of leather so that the surface of the top layer of leather has a beautiful printed pattern. Printed top layer leather is generally processed through depilation, degreasing, liming, deliming, pickling, tanning, retanning, dyeing, fatliquoring, drying, softening, finishing and printing. And the existing printing equipment all is to carry out direct embossing process to the top layer leather, does not carry out the leveling process to the top layer leather in the early stage, thus makes easily because of the folding of the top layer leather in the process of printing, and makes the top layer leather Parts of the area were not embossed, resulting in lower product quality for the top coat. [0003] In view of this, the applicant condu...
