Embodiment 1

[0026] The preparation method of environmental protection ecological white tanned lambskin of the present invention, the detailed steps of described preparation method are as follows:

[0027] a. Soaking in water: according to each foot 2 The ratio of adding 4 liters of water to the lamb skin is to prepare room temperature water, and add 0.5g / L soaking agent, 1.0g / L anionic degreasing agent, 1.0g / L nonionic degreasing agent and 0.5g / L soda ash, and then test after scratching evenly Its pH value is 7.0. After it is completely dissolved, put it into the skin, then put it into the raw lamb skin for soaking, paddle it for 10-15 minutes every hour, let it stand overnight, wash it once, then shave and remove the flesh;

[0028] b. Degreasing: according to each foot 2 The ratio of adding 4 liters of water to the lamb skin, prepare the water, raise the water temperature to 35-38 ℃, and add 1.5-2g / L anionic degreasing agent, 2.0g / L non-ionic degreasing agent and 0.5g / L soda ash, paddl...

Abstract

The invention discloses a method for manufacturing environment-friendly ecological tanned lamb skin. The method comprises the following steps: firstly, soaking a raw material lamb skin into water, adding degreasant and sodium carbonate in the soaking process, and removing hair and meat in the water soaking process; putting the lamb skin in water, adding degreasant and sodium carbonate for soaking and removing fat, and removing meat for the second time; putting into water for the second time to soften the lamb skin and removing fur and meat; pickling and softening, and taking out the skin and standing still for two days; tanning, taking out and standing still for two days; performing primary treatment, putting into water, adding syntans, a fatting agent and formic acid, soaking, taking out, standing for one day, performing oxidation washing and reduction bleaching, and finally finishing, thus obtaining a product. When tanned lamb skin is manufactured by using the method, environment pollution can be reduced and relevant maintenance expense for wastewater treatment and the like can be reduced, so that the production cost can be reduced and moreover the manufactured product is excellent in property.

Description

technical field [0001] The invention belongs to the technical field of wool and sheepskin industry processing and production, and in particular relates to a production method of environmentally friendly and ecological white tanned lambskin. Background technique [0002] Tanning is an essential and very important process in the wool leather manufacturing process. Untanned leather is raw hide and cannot be used; after tanning, raw hide becomes leather, which has the characteristics of softness, storage resistance, water permeability, and washability. And other people's needs, clothing performance. For a long time, chrome tanning has been used in the production and processing of wool sheepskin. This method will cause serious pollution to the environment from the tanning process to the sewage treatment. In recent years, my country has attached great importance to environmental protection, vigorously developed and implemented energy-saving, emission-reducing, and consumption-red...
