The application of tannin extract in the textile industry mainly includes the following aspects:
Binder for textiles: Tannin extract can be used as a binder for textiles, used for the preparation of yarn slurry, and improve the strength and uniformity of the yarn.
Hydrophilic cross-linking modification: Tannin extract is used as a filling material to hydrophilically cross-link the microfiber synthetic leather base fabric to improve the hygroscopicity and water vapor permeability of the base fabric. Studies have shown that the base fabric modified by cross-linking agents such as tannin extract has an increase in hygroscopicity of 35.66% and water vapor permeability of 53.23%. At the same time, the tensile strength is improved, and the modification does not affect the softness of the base fabric.
Improving dyeing fastness: Tannin extract uses metal salts as mordants to dye leather, which can not only solve the problem that plant dyes cannot be mass-produced, but also solve the problem that plant dyes have low dyeing fastness.
Improve fiber properties: The looseness of the base fabric fibers after tannin extract modification is significantly improved, the wettability of the base fabric is increased, the specific surface area is increased, the fiber regularity is changed, and the base fabric after cross-linking modification has good thermal stability.
