Non-woven fabrics originated in the United States, and the technology is mature

Non-woven processing, as the 'post-process' of the entire non-woven processing process, has gradually developed following the development of non-woven industrial production. Since non-woven fabrics have only been produced on a large scale in recent decades, their processing methods are mainly formed by directly adopting or learning from the dyeing and finishing technology of traditional textiles.

From the beginning of the 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 industry has entered the budding period of development. During this period, the main raw materials produced are mainly low-grade raw materials such as textile factory scraps and regenerated fibers, and the products are mainly thick batts. Class products, the use is limited to low-level use to replace textiles. The production scale is small and the product variety is single, so most of the products are not processed, but research on non-woven processing has begun to appear. It can be seen from the patent applications in the United States and the United Kingdom that during this period, the average number of patents related to non-woven fabric processing increased from one or two cases per year in the 1940s to six or seven cases in the 1950s.

From the late 1950s to the late 1960s

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

From the early 1970s to the end of the 1980s

From the early 1970s to the late 1980s, the world's non-woven production continued to grow rapidly, and new features were proposed for the function of non-woven fabrics. requirements, the practicality of functional processing technology, and endow the product with some special functions. Such as hydrophilic processing of adsorbent materials, antibacterial processing of medical and sanitary materials, antistatic processing of filter materials, radiation protection processing of protective materials, soft processing of wiping materials, etc.

Since the 1990s

Since the 1990s, non-woven technology has formed dozens of production lines represented by spunlace, meltblown, spunbond and composite. With the further expansion of technology, application fields and more and more functions, the non-woven fabric processing technology has continued to develop, and its role in the non-woven fabric processing process has become more and more irreplaceable. More and more high-tech means such as far-infrared processing technology, electret technology, and plasma technology are applied to the processing of non-woven fabrics.

At present, non-woven fabric processing technology has gradually formed a complete system, which can endow non-woven fabrics with new functions and new vitality, and subsequently produce a variety of friendly products, which have been increasingly used. Many domestic and foreign experts and scholars attach importance to it.
