Abstract

The invention discloses an anti-wrinkle leather shoe material and a manufacturing method thereof, and the manufacturing method comprises the following steps: putting wet blue leather into warm water, adding a penetrant, sodium acetate and a rotary drum, and then adding baking soda and the rotary drum; wet blue leather is washed at normal temperature, naturally aired and then put into a rotary drum for chrome tanning; the leather is placed in a rotary drum, retanning, taking out of the drum, horse building and aging are conducted; the surface of the leather is evenly coated with a layer of pretreatment liquid in a rolling mode and dried, then the surface of the leather is evenly coated with a layer of treatment liquid II in a spraying mode, baking is conducted, the leather is placed on a tumbling mill to be subjected to tumbling, and a leather crude product is obtained; and carrying out after-finishing and drying on the leather crude product to obtain the anti-wrinkle leather shoe material. According to the anti-wrinkle leather shoe material, multi-stage drum treatment is adopted, the softness of a leather material, the uniformity of an internal net-shaped structure and the fiber lightness are improved, the treatment liquid is subjected to roller coating and spraying in the later period, layer-by-layer protection is achieved, the wrinkle resistance and the surface antifouling capacity of leather are improved, and the service life of the leather is prolonged.

Description

technical field [0001] The invention relates to the technical field of leather material processing, in particular to an anti-wrinkle leather shoe material and a manufacturing method thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather products are mostly used in the fields of leather shoes, leather clothes, leather bags, leather sofas, etc. When used as raw materials for leather shoes, because they need to be slightly folded several times during the wearing process, creases are easy to appear, which will not only affect the appearance of wearing, but also Can shorten the service life of leather shoes, and only adopt anti-wrinkle coating and can influence the soft comfort of leather again. [0003] Chinese patent CN11180900~A discloses a kind of tortuous antibacterial leather and its preparation method, including rough leather (1) and protective lay...
