Bicomponent Staple Fibers PE/PET

Bicomponent Staple Fibers PE/PET

1. What is ES fiber?

ES refers to "EthylenePropylene Side By Side", which is a twocomponent coreskin composite fiber. The raw materials are generally PE/PP or PE/PET. The bico fiber main specifications are 1.5DX38mm, 3DX51mm, 4DX51mm, 2DX3MM, 2DX4mm. It is generally used as a non-woven fabric raw material for sanitary products.

2. Non-woven process of ES staple fiber

There are two main processes for ES staple fiber non-woven fabrics:

1). Hot air production line. Hot air non-woven fabrics are made by using hot air from drying equipment to penetrate the fiber web after the fibers are combed, so that they are heated and bonded to form non-woven fabrics.

2). Hot rolling production line. Hot rolling is the last process of spunbond non-woven fabrics. It relies on hot rolling rollers to melt and reinforce the fibers. Generally, there are rolling points, and the fibers melt at the rolling points.

At present, ES fibers in China are mainly used in hot air non-woven fabrics.

3. Application fields of ES staple fiber non-woven fabrics

ES hot air nonwoven fabrics have the characteristics of high fluffiness, good elasticity, soft touch, strong warmth retention, good air permeability and water permeability, but its strength is low and easy to deform.

It is widely used in the manufacture of disposable products with its unique style, such as baby diapers, adult incontinence pads, fabrics for women's hygiene products, as well as napkins, bath towels, disposable tablecloths, etc.; thick products are used to make winter clothes, bedding, baby sleeping bags, mattresses, sofa cushions, etc. Highdensity hotmelt adhesive products can be used to make filter materials, sound insulation materials, shock-absorbing materials, etc.

Bicomponent fiber are the fibers produced by mixing two different polymers to achieve the properties of both fibers. For example, Polyester and Nylon may be mixed together in extrusion. The polymers in the bicomponent may have entirely different physical and chemical properties.

The highquality twocomponent staple fiber PE/PET produced by Fujian Foody New Materials Co., Ltd. is suitable for the production of hot air nonwoven fabrics, cores and fluffy nonwoven fabrics. Compared with the twocomponent staple fiber PE/PP commonly used in the market, our PE/PET is more elastic and can increase the fluffiness and softness of non-woven fabrics, making the product feel more silky!
