PP spunbonded nonwovens are widely used in the field of daily necessities, and their development and evolution are mainly reflected in three aspects.

As an industrial basic material, PP spunbonded nonwovens (spunbonded nonwovens made of polypropylene) have been widely used in the field of daily necessities. Its development and evolution are mainly reflected in the advancement of process technology, the expansion of application fields and industrial policies. Promote three aspects.

Process technology development

The spunbond method originated in the 1950s and was simultaneously developed by DuPont Company of the United States and Freudenberg Company of Germany. It achieved industrial production in the late 1960s. The method forms a filament network structure through melt spinning, omitting the fiber processing process of traditional textiles, and has the advantages of high production efficiency and low cost. Globally, melt spinning (including spunbond) production accounts for 40%-50%, and the market share in North America reached 54% in 1998.‌

Industrial policy promotion

In recent years, the China government has introduced a number of policies to support the upgrading of the nonwoven industry:

The 2022 "Guiding Opinions on High-Quality Development of the Industrial Textile Industry" proposes that by 2025, the numerical control rate of key processes in the industry will reach 70%, and 3-5 global leading companies will be cultivated.‌

The policy focuses on promoting technological innovation and high-end transformation, such as encouraging companies to develop technologies such as bicomponent fibers and smart production lines to enhance the added value of products.‌

The current global nonwoven market presents a pattern in which three major technical paths coexist:

Spunbonded method

Melt-blowing method

Wet/dry
