Technical Field

The invention relates to the technical field of glove processing, in particular to a wear-resistant protective glove and a manufacturing method thereof.

Background

In recent years, with social development and continuous progress of textile technology, people pay more and more attention to protective textiles while paying more attention to production safety. Gloves have long been used as hand protection products for the highest rate of human injury. However, because the common canvas glove and the cotton glove have low strength and poor wear resistance, the gloves have single function, cannot meet the requirement of people on safety in the production process, and are greatly limited in application. With the development of modern textile technology and the emergence of high-performance coatings with high strength and high modulus, people are beginning to pay attention to the development of high-strength protective gloves by adopting wear-resistant coatings. However, in the existing glove preparation process, the coating rubber material attached to the surface layer of the glove has poor adhesion and poor wear resistance, so that the glove has short service life and poor protection effect.
