Abstract

The invention relates to heat-preservation and cold-proof waterborne clothing leather and a preparation method thereof. The main principle is that in a dry process overlaying process, a hollow microsphere material is selected as a main heat-preservation material and is matched with waterborne polyurethane to form a film substance so as to prepare semi-finished low-heat-conductivity heat-preservation and cold-proof waterborne polyurethane clothing leather; and 8-methyl-N-vanillyl-6-nonene and far-infrared ceramic powder are added in the leather making process, the 8-methyl-N-vanillyl-6-nonene is heated by 2-3 DEG C after absorbing water vapor or making contact with the skin, and the far-infrared ceramic powder can release far-infrared rays with the wavelength of 4-14 microns after absorbing external heat energy and can be easily absorbed by the human body, so that the heat-preservation and cold-proof effects are achieved.

Description

technical field [0001] The invention belongs to the field of water-based clothing leather, in particular to a heat-preserving and cold-proof water-based clothing leather and a preparation method thereof. Background technique [0002] After nearly 10 years of development, the production process of water-based garment leather is approaching maturity, but there is a lack of functional products, and the products in special fields are single. Traditional clothing leather has the disadvantages of poor air permeability, water vapor is not easy to volatilize, obvious chills after sweating, and poor wearing comfort. In low temperature weather, especially in cold winter, consumers experience bad. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat-preserving and cold-proof water-based garment leather to overcome the shortcomings of traditional garment leather in the prior art, such as poor air permeability, difficult vo...
