The raw materials of natural leather materials are various animal skins. Natural leather has an elegant appearance, soft and full feel and good durability. It is very popular among users. However, due to the high price, the use of leather bags has been restricted to a certain extent. Many natural leather materials are used in luggage products, and different types of leather have great differences in performance.
The appearance of artificial leather is similar to natural leather, with low price and various colors. It has been widely used in industrial and agricultural production and people's lives. The artificial leather produced in the early days was made of polyvinyl chloride coated on the surface of the fabric, and its appearance and practical properties were poor. In recent years, polyurethane synthetic leather varieties have been developed, which have significantly improved the quality of artificial leather, especially non-woven substrates. The fabric and surface layer are made of polyurethane porous material imitating the structure and composition of natural leather, which has good practical performance. Therefore, artificial leather is classified according to raw materials and can be divided into two categories, namely, polyvinyl chloride artificial leather and polyurethane synthetic leather. Among them, in the artificial leather series, there are materials such as artificial leather, artificial varnish leather, artificial suede leather, and polyvinyl chloride plasticized film. In the synthetic leather material series, the most widely used synthetic leather is coated with a polyurethane foam layer, which looks very similar to natural leather.
The fabric can be used for both fabrics and linings in bags. Two types of fabrics are used in the fabric: PVC coated and ordinary fabrics. Among them, the polyvinyl chloride coating is a textile with transparent or opaque polyvinyl chloride film attached to the front or back, such as Scottish checkered cloth, printed cloth, and rayon cloth. This material has a variety of colors and patterns, and has high water resistance and abrasion resistance, and can be used to make travel bags, sports bags, student bags, etc. Among ordinary fabrics, canvas, flannel, twill and Scottish plaid can be used for bag making products.
The bag liner is mainly used to assist the product modeling and at the same time play a role in protecting the product fabric. The main varieties are artificial leather and textiles. In artificial leather products, softer varieties are mainly used, such as foamed sheepskin; in textiles, silk fabrics in chemical fiber fabrics are mainly used, and cotton cloth is sometimes used in some luggage products.
