Technical Field

[0001] The invention relates to the technical field of gloves, and in particular to a method for preparing environmentally friendly and renewable gloves. Background Art

[0002] In daily life, gloves can prevent hand injuries and contamination. For example, they form a protective film when in contact with harmful substances, blood, etc. They are suitable for household, industrial, medical, beauty and other industries. At the same time, during medical examinations, diagnosis or surgery, gloves can prevent cross-infection between patients and users. Gloves can be divided into food grade, medical grade, industrial grade, etc. according to their use to meet the needs of different industries. Due to their multiple functions and wide applicability, gloves have become an indispensable hand protection tool in all walks of life.
