As we all know, our Yanpeng non-woven machinery production line is of high speed and excellent quality.The quality of the cloth produced is not only the precision and excellence of the machinery itself, but also closely related to the quality of raw materials in the silo.

Today, I would like to introduce the selection and use of raw materials in the non-woven industry.

All kinds of raw materials used in the production of spunbonded and melt blown nonwovens are "thermoplastic" plastics.

Thermoplasticity refers to the characteristic that plastics in a specific temperature range can be heated and softened repeatedly and hardened after cooling.

All kinds of raw materials used in spunbonded and melt blown nonwovens are solid at room temperature, sometimes referred to as "chip" or "resin".

The raw materials used in the production process of spunbonded and melt blown nonwovens mainly include polypropylene (PP), polyester (PET), polyamide (PA), polyethylene (PE), polylactic acid (PLA), etc. PP is the most commonly used, most used and most widely used raw material.

When using different raw materials, the characteristics of products will be different, the production process will be different, and the performance and configuration of equipment will be different, which will have a significant impact on the use of products, market, economic benefits and the price of production line.

Therefore, this is the first prerequisite for determining the performance index of the production line.

The average molecular weight, molecular weight distribution width and rheological properties of raw materials are closely related to spinnability and product properties.

The characteristics of various auxiliary materials used in the production process should match the properties of the main materials. For example, the color masterbatch carrier used for PP spinning should also be PP, but its fluidity is higher.

On the same spinning device, most spinning systems can only use one raw material, that is, they can only use this raw material to produce products. Each fiber of the fiber web is only composed of substances with the same performance. This fiber can be called single component fiber.

If two same or different raw materials can be used for composite spinning on the same spinning device at the same time.

That is, two different melts are ejected at the same time in the same spinneret hole. The fiber produced by this process is called two-component fiber.

This fiber can be used to produce two-component nonwovens. This production line is a two-component production line.
