1. Development history of nonwoven fabrics:
Phase 1: The budding period from the early 1940s to the mid-1950s. Most of the equipment used existing textile equipment or modified natural fibers.
Phase 2: Commercial production from the late 1950s to the late 1960s. Mainly using dry and wet processes, with many applications of chemical fibers.
Phase 3: An important period from the early 1970s to the late 1980s. A complete set of polymerization and extrusion production lines emerged, using various chemical fibers such as low melting point fibers, heat-bonding fibers, bicomponent fibers, and ultrafine fibers.
Phase 4: From the early 1990s to the present, a period of global development. Nonwoven fabric enterprises have been strengthened through mergers, alliances, and reorganizations, with advanced skills, sophisticated equipment, and significantly increased production capacity.
2. Basic principles of nonwoven fabrics:
(1) Development history of nonwoven fabrics:
Phase 1: The budding period from the early 1940s to the mid-1950s. Most of the equipment used existing textile equipment or appropriately modified natural fibers.
Phase 2: Commercial production from the late 1950s to the late 1960s. Mainly using dry and wet processes, with many applications of chemical fibers.
Phase 3: An important period from the early 1970s to the late 1980s. A complete set of polymerization and extrusion production lines emerged, using various special chemical fibers such as low melting point fibers, heat-bonding fibers, bicomponent fibers, and ultrafine fibers.
Phase 4: From the early 1990s to the present, a period of global development. Nonwoven fabric enterprises have been strengthened through mergers, alliances, and reorganizations, with advanced skills, sophisticated equipment, and significantly increased production capacity.
(2) Basic principles of nonwoven fabrics:
Nonwoven materials, also known as nonwoven fabrics, nonwoven textiles, nonwovens, or nonwovens, are a processing technology that originated from textiles and surpasses textiles. Different nonwoven fabric processing technologies have their corresponding processing principles.
However, from a macro perspective, the basic principles of nonwoven fabric technology are the same and can be described by the following four processes:
(1) Fiber preparation; (2) Network formation; (3) Reinforcement; (4) Finishing.
