Embodiment Construction

[0030] The technical solutions of the present invention will be further specifically described below through examples.

[0031] A kind of goat shoe upper leather production process, concrete operation process is as follows:

[0032] Fur: ​​The domestic Hankou road goat skin is the preferred material. This leather is thick, rich, yellowish with fleshy red, and the grain is flat and fine.

[0033] Soaking in water: the purpose is to return the moisture of the raw hide to the fresh hide state, remove inorganic and organic dirt such as sediment, blood stains, salt and preservatives on the hide, and remove part of the soluble non-fibrin in the hide to infiltrate the material of the subsequent process And lay the foundation for the role. Use water between 18-22°C, the liquid ratio is 300 times the tare weight, the speed is 3-4 rpm; the time is 18-22 hours; add an appropriate amount of preservatives and immersion aids, and the ratio of skin to liquid and the temperature to the speci...

Abstract

The invention aims to provide a process for making goat upper leather. The process specifically comprises the following flows in sequence: soaking, fleshing, painting with lime, dehairing, liming, deliming, softening, pickling, tanning, blue rawhide lot grouping, wringing, shaving, re-tanning and dyeing, secondary wringing, vacuumizing, hang airing, water returning, vibrating staking, setting out, toggling, trimming, buffing and finishing. The process has the beneficial effects that proper and moderate liming aids are selected to promote the limed hide to swell moderately, so that the tear strength of the hide is improved, the growth lines and back lines of the rawhide are completely unfolded and the grain side is flat and fine, thus increasing the leather yield; and the location difference of the hide body is reduced, the plumpness of the whole hide is improved and the hide body can be moistened.
