Problems solved by technology

Such a high temperature and high humidity environment is particularly prone to the growth and reproduction of bacteria and fungi
[0004] The leather shoes that people wear are made of leather and outsoles, and the part that is in direct contact with the feet is leather. Natural leather has good water absorption and air permeability, but people add finishing materials to the leather surface to make it more beautiful. , resin, wax and other chemicals, the air permeability becomes very poor

preparation example Construction

[0024] The invention provides a kind of preparation method of antibacterial deodorization leather, comprises the following steps:

[0025] (1) After degreasing and neutralizing the wet blue leather successively, a neutral base material is obtained;

[0026] (2) rotating and mixing the neutral base material obtained in the step (1) with ammonia, dyestuffs and micron silver powder in a drum to obtain dyed leather;

[0027] (3) carrying out fatliquoring and acid-fixing treatment successively to the dyed leather obtained in the step (2) to obtain primary leather;

[0028] (4) The primary leather obtained in the step (3), water, deodorant resin mixture, anionic deodorant, cross-linking agent, silicone softener and formic acid are rotated and mixed in a drum to obtain an antibacterial deodorant Leather; the deodorant resin mix contains fragrance and resin nanoparticles.

[0029] In the present invention, unless otherwise specified, the materials used in the preparation process are...

Embodiment 1

[0048] Weighing: Weigh the raw material wet blue hide, and take the weight of the wet blue hide as 100wt.%. The mass involved in the subsequent steps is based on this.

[0049] Degreasing: Put the wet blue hide into the drum, add 45°C water, degreasing agent and formic acid, and then rotate for 60 minutes, then wash with water to remove the residual formic acid and degreasing agent on the surface of the wet blue hide; Liquid removal; Wherein, the wet blue leather mass taken by weighing is 100wt.%, the addition of water is 100wt.%, the addition of degreasing agent is 0.5wt.%, and the addition of formic acid is 0.2wt.%.

[0050] Neutralization: At room temperature, add 100wt.% water at 30°C to the drum that retains the degreased wet-blue leather, then add 3% baking soda and 3% ammonium bicarbonate and continue to rotate for 90 minutes. Measure the pH value of the liquid in the drum at 6.5; finally wash with water, and remove the liquid in the drum after washing.

[0051] Dyeing...

Embodiment 2

[0057] Prepare antibacterial and deodorant leather according to the method of Example 1, the difference is that in the dyeing process, the particle size of the micron silver powder is 3 μm, and the dosage is 0.2%; 1:2 mixture of essence and polypropylene resin nanoparticles (particle size less than 1μm), anionic ion deodorant is nano-scale ferrous chloride, cross-linking agent is methacrylic acid, silicone softener is containing dioxide Fatty alcohol sulfate derivatives of silicon; and the amount of the deodorant resin mixture is 0.05%, and the amount of the anionic deodorant is 2.0%.

Abstract

The invention provides a preparation method of anti-bacterial deodorant leather. The preparation method comprises the steps that wet blue leather is degreased and neutralized sequentially, micron-sized silver powder is added in the dyeing process to improve the antibacterial property of the leather, and then fatliquoring softening and solid acid treatment are conducted, so that primary leather isobtained; and afterwards, the obtained primary leather, water, a deodorant resin mixture, an anion deodorant, a cross-linking agent, a silicone softener and formic acid are rotary mixed in a drum, sothat the anti-bacterial deodorant leather is obtained. Results of the embodiment show that the anti-bacterial deodorant leather prepared through the method has a good anti-bacterial deodorant functionand the comfort is improved.

Description

technical field [0001] The invention relates to the technical field of leather material preparation, in particular to a preparation method of antibacterial and deodorizing leather. Background technique [0002] More than 80% of people will have mild or severe foot odor. There are many reasons for foot odor. The main causes are: [0003] Humid environments and stuffy enclosed spaces. The soles of the feet emit a lot of sweat every day. When the shoes are worn tightly and the ventilation is not good, there will be a lot of moisture in the shoes, and the temperature inside the shoes will also rise. Such a high temperature and high humidity environment is particularly prone to the growth and reproduction of bacteria and fungi. [0004] The leather shoes that people wear are made of leather and outsoles, and the part that is in direct contact with the feet is leather. Natural leather has good water absorption and air permeability, but people add finishing materials to the leath...
