Non-woven fabrics can be classified in any way.
Non-woven fabrics can be classified according to the purpose of the product, which can be divided into medical and health care materials, construction geotechnical materials, industrial cloth materials, living and household decoration materials, agricultural materials and materials in other fields. According to the product usage time, it can be divided into disposable type and durable type (disposable type refers to a product that is only used once or several times and then no longer used, and durable type requires a longer re-use time) . According to the thickness of the product, it can generally be divided into thick nonwoven fabric and thin nonwoven fabric. 1. According to the way of fiber formation, non-woven fabrics are classified into three types: dry-laid, wet-laid and polymer extrusion. (1) Dry-laid It refers to the fibers in the dry state, the use of mechanical carding or air-laid methods to make a web, and then use mechanical, chemical bonding or thermal bonding to strengthen into a non-woven fabric. (2) Wet-laid webs use water as the medium, and short fibers are suspended in water. The paper-making method is used to form fiber webs by the action of water, and then the fibers are reinforced by chemical bonding, mechanical or thermal bonding. Weaving cloth. (3) Polymer extrusion method refers to the formation of filaments or short fibers from melt or solution through spinneret holes. These filaments or short fibers are laid on a moving conveyor belt to form a continuous web, which is then mechanically, chemically bonded or thermally bonded to form a nonwoven fabric. 2. Classification of fiber reinforcement methods The reinforcement process of fiber webs is generally divided into three categories: mechanical reinforcement, chemical bonding and thermal bonding. The specific reinforcement method depends on the type of fiber mesh and the performance of the product.
