Non-woven fabrics for agricultural purposes are manufactured through a process that involves the bonding of fibers using methods such as thermal, chemical, or mechanical techniques, rather than conventional weaving. Here's a general overview of the production process:
1.Fiber Selection: Suitable fiber materials, such as polypropylene (PP), polyester (PET), nylon, or recycled fibers, are chosen based on their intended application.
2.Blending and Opening: Different types of fibers are blended together to achieve desired properties. These blended fibers are then opened and dispersed to form a uniform fiber web.
3.Pre-treatment: After the fiber web formation, pre-treatment processes like thermal bonding or chemical treatments may be applied to enhance fiber bonding and other performance characteristics.
4.Web Formation: The fiber web is bonded together using methods such as thermal bonding, needle punching, or adhesive bonding to create a continuous non-woven fabric. The choice of method depends on the desired properties of the final product.
5.Post-processing: Depending on requirements, post-processing such as heat setting, coating, dyeing, or other surface treatments may be applied to the non-woven fabric to enhance its performance or aesthetics.
6.Cutting and Winding: The finished non-woven fabric is cut to the desired dimensions and either wound into rolls or cut into sheets for ease of transportation and use.
Through this process, non-woven fabrics can be tailored to various agricultural applications such as cover films, protective covers, ground covers, etc., providing effective solutions for agricultural production needs.
