Problems solved by technology

[0003] The traditional polyurethane synthetic leather for belts not only has large wrinkles and average strength, but the synthetic leather is not resistant to folding, creases and cracks will occur after folding, and it is easy to stretch and start to mold, especially in a humid environment. It plays the role of restraint for a long time and has a certain decorative effect. Therefore, it not only has important requirements for its performance, but also its surface should have sufficient aesthetics. However, the current belt is easy to wrinkle and poor in shape after long-term use. No automatic recovery after a crease occurs, so it does not meet the demand for high-quality belts

Abstract

The invention discloses a tensile crease-resistant synthetic leather fabric for a belt, which comprises a base cloth layer, a crease-resistant layer, a tough slurry layer, a composite slurry layer, asurface layer and a high mirror surface layer. The base cloth layer and the crease-resistant layer are formed by blended spinning. The invention discloses a preparation method of the tensile crease-resistant synthetic leather fabric for a belt. The preparation method comprises the following steps: S1, blended spinning; S2, coating of tough slurry; S3, coating of composite slurry; S4, coating of asurface layer; S5, spray-coating of a high mirror surface layer; and S6, post-processing. According to the invention, the purposes of shape memory performance and antibacterial function are achieved,the tensile strength, tearing strength and wear resistance of the synthetic leather are improved, the synthetic leather has the characteristics of being good in hand feeling, fine and smooth in texture and good in air permeability, the surface color of the treated leather is uniform and bright, the physical and chemical properties of the synthetic leather can be improved, and the characteristics that the finished leather does not wrinkle and can be folded without folds are met.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a tensile and wrinkle-resistant synthetic leather fabric for belts and a preparation method thereof. Background technique [0002] Nowadays, polyurethane synthetic leather products have been widely used in people's daily life, especially in the field of sports shoes. With the development of social economy and the improvement of people's living standards, people's demand for leather is not only limited to durability , and more and more attention is being paid to its additional functions. Synthetic leather simulates the composition and structure of natural leather, and can be used as a plastic product for its substitute material. In the production process of synthetic leather, the impregnated non-woven fabric is usually used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Both the front and back are very similar to leather, and have ...
