A kind of processing method of imitation ostrich pattern leather

Abstract

The invention discloses a processing method of ostrich texture simulated leather. The processing method is characterized by comprising the following steps of flatly spreading a delimed and softened pelt on a pin board, wherein a grain side of the pelt is upward, and a flesh side is in contact with wood screws; afterwards, uniformly brushing a pattern fixing agent on a part, which is convex on thepin board, of the pelt, wherein the pattern fixing agent is at least brushed for 1 time; and after the brushing of the pattern fixing agent is finished, standing for at least 5min, and carrying out acid pickling, tanning, after-tanning wet processing and coating operation according to normal operation, thus obtaining an ostrich texture leather finished product. Distances among wood screws on the pin board are 2cm to 6cm; and the heights at which the wood screws protrude the plane of the pin board are 0.5cm to 3cm. The pattern fixing agent is an aldehyde solution with the pH (potential of Hydrogen) of 8.0 to 9.5; and the aldehyde solution is prepared from any one of formaldehyde with a mass friction of 40%, glutaraldehyde with a mass friction of 50%, modified glutaraldehyde with a mass friction of 45%, acetaldehyde with a mass fiction of 60% or furaldehyde with a mass friction of 50%. The delimed and softened pelt is any one of a cattle hide, a buffalo hide, a dzo hide or a yak hide. The method is simple, low in cost, high in operability, and moreover, easy in style change, and is used for producing ostrich skin pattern simulated leather with different characteristics.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and in particular relates to a method for producing ostrich-skin pattern leather from cowhide. Background technique [0002] Compared with conventional leather products, ostrich leather has a unique irregular point-like raised pattern, which is very popular in the market. However, the current ostrich breeding technology is complex, the breeding cycle is long, and the breeding volume is small, which has greatly restricted the source of ostrich raw skin, and the supply of natural ostrich skin is difficult to meet the market demand. Therefore, prepare the leather of imitation ostrich pattern with conventional leather products, both can satisfy the demand of market to ostrich pattern leather, can reduce product cost again compared with utilizing ostrich skin as raw material production. [0003] At present, the main method of producing special pattern leather is embossing. However, the ost...

Problems solved by technology

However, this method requires multiple extrusion moldings to produce the pattern of ostrich skin. The operation is complicated, and it requires special machinery and equipment, which requires a large investment. It is not suitable for industrial production, and it is not conducive to reducing production costs and improving production efficiency.

In addition, there is no technical information about using conventional pig, cow and sheep skin to make imitation ostrich pattern leather in the currently disclosed methods
