2400 Double beam PP Spunbond Production Line

Overview

Spunbond is an important and widely used method of producing nonwovens by polymer extrusion. It applies fibre spinning principles to lay continuous filaments into a web during polymer spinning. The web is then consolidated by mechanical, chemical or thermal bonding. Spunbond production has a short process route and high efficiency, with further cost advantages at large scale. Spunbond nonwovens also have favourable strength, elongation and machine-direction/cross-direction strength characteristics. Applications include clothing, decorative materials, medical and hygiene products, geotechnical materials and agricultural materials, providing a broad market for spunbond nonwovens.

This line produces continuous-filament polypropylene spunbond nonwoven fabric using an integrated single-plate slot air-drawing system. The supplied equipment and process technology have been proven in production and are designed for stable production and long-term operation. The process is automatically controlled from feeding to fabric output and uses AC variable-frequency control(with energy-saving and reliability advantages over traditional DC speed control), together with touch-screen control. The equipment has a practical structure, high operating efficiency, low production consumption, convenient operation and a low incidence of operating faults.

The equipment can produce nonwoven fabric in different colours, two-colour nonwoven fabric(for example, one green layer and one red layer),composites(for example, one water-repellent layer and one hydrophilic layer)nonwoven fabric.The nonwoven equipment manufactured by our company has stable quality, a robust structure, convenient operation, a high degree of automation and high output for its specification. It is trusted by users in the industry.

General overview

Spunbond is an important and widely used method of producing nonwovens by polymer extrusion. It applies fibre spinning principles to lay continuous filaments into a web during polymer spinning.

Spunbond nonwovens also have favourable strength, elongation and machine-direction/cross-direction strength characteristics. Applications include clothing, decorative materials, medical and hygiene products, geotechnical materials and agricultural materials, providing a broad market for spunbond nonwovens.

 The non-woven equipment is filament polypropylene spunbonded non-woven equipment, the unit adopts the current more advanced single board integral slit air draft technology. The process equipment and technology provided is a reliable, advanced and mature set of equipment and technology proved by production practice, which can meet the buyer's stable production and long-term operation. Automatic control from feed to cloth; use AC frequency conversion technology (than the traditional DC speed control system has the characteristics of power saving and high reliability), select touch screen control. The technology has the characteristics of reasonable equipment structure, high operation efficiency, low production consumption, convenient operation and less equipment operation failure.

 The equipment can according to the requirements of the manufacturer, the production of various colors of non-woven materials, two-color non-woven fabric (such as a layer of green and a layer of red), composite (such as a layer of water repellent and a layer of hydrophilic) non-woven fabric. The unit produces non-woven equipment, the quality of the equipment is stable, stable structure, easy to operate, high degree of automation, higher output than the same specifications of equipment, in the same industry by the majority of users.
