Since the release of the plastic limit order, spunbond non-wovens have served as an environmental guardian against white pollution. Although China's spunbond non-wovens industry is developing rapidly, there is still a big gap compared with the internationally advanced spunmelt industry. Therefore, although spunbonded non-wovens have broad market prospects, the entire industry remains to be adjusted.

Spunbond non-woven fabric: After the polymer has been extruded and stretched to form intermittent filaments, the filaments are laid into a net, and the web is then bonded, thermally bonded, chemically bonded or stagnant. To make the web into a non-woven fabric.

Spunbond non-wovens advantages:

High strength, high temperature resistance (sustainable application in the case of 150 ° C), aging resistance, UV resistance, high stretch rate, strong strength and breathability, corrosion resistance, sound insulation, anti-mite, non-toxic.

Main use of spunbond non-woven

The main products of spunbonded non-woven fabrics are polypropylene, polyester (long-fiber, staple fiber). The most common and most commonly used are non-woven bags, non-woven packaging, etc., and are also easily identifiable because of spinning The nip of the viscous non-woven fabric is diamond shaped.

The application level can also be used as a flower packaging cloth, luggage cloth, etc., which is resistant to abrasion, strong hand feeling, etc., making him the best choice for making such products.

Spunbond non-woven process

Polymer (polypropylene + return material) - high-temperature melt extrusion of large snails - filter - metering pump (quantitative delivery) - spinning (spinning inlet up and down stretching) - cooling - airflow Traction - mesh curtain netting - upper and lower pressure roller (pre-reinforcement) - hot rolling mill (reinforcement) - winding - inverted cloth cutting - weighing packaging - finished product storage

Technical type of spunbond non-woven

The world's spunbond non-woven fabrics mainly include Leccofel technology from Leifen, Germany, STP technology from Italy, and Kobe steel technology from Japan. The current situation, especially with Reifen technology, has become the mainstream technology in the world. The fourth generation technology has been developed. It is characterized by the use of negative pressure super-high-speed air drafting, and the fiber can be stretched to about 1 denier. Many companies in China have already carried out imitation. Due to the fact that many of the core technologies have not been solved or mastered, it will take time for domestic equipment manufacturers to reach the technical level of Reifen.
