Non-woven fabric originated in the United States, with mature technology

As the 'back process' of the entire processing process of non-woven fabrics, non-woven fabric processing has gradually developed following the development of non-woven fabric industrial production. Since non-woven fabrics have only formed large-scale production in recent decades, their processing methods are mainly formed by directly adopting or adopting traditional textile dyeing and finishing technology.


From the early 20th century to the 1950s


The industrial production of non-woven fabrics originated in the United States. As early as the early 20th century to the 1950s, the modern non-woven fabric industry has entered the embryonic period of development. In this period, the main production materials are mainly low-grade raw materials such as textile mill scraps and recycled fibers. Its products are mainly thick wadding. Class products, the use is limited to low-level uses to replace textiles. The production scale is small and the product variety is single, so most of the products are not processed, but the research on the processing of non-woven fabrics has begun to appear. It can be seen from the patent applications of the United States and the United Kingdom that the average number of patents for non-woven fabric processing during this period has ranged from one or two cases per year in the 1940s to six or seven cases in the 1950s.


Late 1950s to late 1960s


From the late 1950s to the late 1960s, non-woven fabric technology quickly transformed into commercial production, and the rapid development of the chemical fiber industry promoted the promotion of non-woven fabric technology. The output of non-woven fabrics has also increased rapidly, and the product variety has expanded rapidly. During this period, the chemical industry closely related to textile processing also made great progress. Such as anti-wrinkle processing, organic silicon processing, PVC coating processing, etc. Since the processing technology in this period was mainly for natural fiber products such as cotton, linen, wool, and silk, most of them rely on traditional textile processing technology. There are mainly rubber emulsion processing for the purpose of imitating traditional textiles, coating processing, non-woven fabric engraving roll hot-rolling processing, and non-woven fabric and traditional textile lamination and compounding.


Early 1970s to late 1980s


From the early 1970s to the end of the 1980s, the world's non-woven fabric output continued to grow at a high speed, and new requirements were put forward for non-woven fabric functions, functional processing technology was practical, and products were given some special functions. Such as hydrophilic processing of absorbent materials, antibacterial processing of medical and sanitary materials, antistatic processing of filter materials, radiation protection processing of protective materials, and soft processing of wipe materials.


Since the 1990s


Since the 1990s, non-woven technology has formed dozens of production processes represented by spunlace, meltblown, spunbond, and composite. The application fields have been further expanded and more and more functions have made non-woven fabrics. With the continuous development of fabric processing technology, its role in the processing of non-woven fabrics has become increasingly irreplaceable. More and more high-tech methods such as far-infrared processing technology, electret technology, plasma technology and so on are applied to the processing of non-woven fabrics.


At present, the non-woven fabric processing technology has gradually formed a complete system, which can give the non-woven fabric new functions and new vitality, and consequently produce a variety of pro-products, which has been used by more and more domestic and foreign Valued by experts and scholars.
