Problems solved by technology

The boot leather used for the boot shaft is required to be thin, soft, and brightly colored. It is extremely important to meet the requirements of the tear resistance index, but the boot leather obtained by using the existing boot leather manufacturing method cannot meet the tear strength index Under the requirements of the requirements, the skin embryo will be torn and shredded under the mechanical force, such as the operation of the drum and the skin embryo stretching process, which will cause the skin embryo to suffer losses, and the loss rate is as high as 4.5%. Some boot leather manufacturing methods often result in uneven skin shape and low cutting rate
In the prior art, a tear-resistant strength fatliquoring agent is added in the retanning and dyeing process of leather, but there is a problem that the added amount is difficult to control. If the added amount is too low, it is easy to cause insufficient tear-resistant strength, and the added amount is too high. Not only is it easy to cause the loose surface of the finished leather, but it will also cause a waste of resources

Abstract

The invention relates to the technical field of leather manufacturing method, and provides a manufacturing method of highly tear resistant ultrathin boot leather. The boot leather prepared by the method has high tear strength and high cutting rate, and is thin and soft. The method comprises the following steps: routine wringing of leather felt, stretching, shaving, retanning and dyeing, removal out of drum and ageing for overnight, stretching, vacuumizing, hanging, drying, moisture regain, mill, toggling and finishing.

Description

technical field [0001] The invention relates to the technical field of leather manufacturing methods, in particular to a manufacturing method of high tear-resistant ultra-thin boot leather. Background technique [0002] With the development of society, daily high-end consumer goods are flooding the entire market, and the fashionable and natural boots give people the feeling of galloping on the grassland, which is loved by modern people. The boot leather used for the boot shaft is required to be thin, soft, and brightly colored. It is extremely important to meet the requirements of the tear resistance index, but the boot leather obtained by using the existing boot leather manufacturing method cannot meet the tear strength index Under the requirements of the requirements, the skin embryo will be torn and shredded under the mechanical force, such as the operation of the drum and the skin embryo stretching process, which will cause the skin embryo to suffer losses, and the loss ...
