Understand the Application of ES Composite Fiber in Air Through Non Woven

The cross section of the same fiber has two or more non mixed polymers at the same time, that is, composite fiber, which belongs to a kind of physically modified fiber. Nowadays, there are more and more kinds of composite technologies and composite fibers. Through composite fiber manufacturing technology, modified fibers with two polymer properties, such as two-component fibers and superfine fibers, can be obtained at the same time. As a kind of composite fiber, ES composite fiber has different processing forms due to different polymers. Air through non woven production is one of the common application fields. This paper briefly introduces the application and application advantages of ES fiber in the production of air through non woven.

 

 

1.ES composite fiber is applied to air through non woven

The application of ES composite fiber in the production of air through non woven mainly uses the melting points of polymers in different skin and core layers of materials. The melting point of polyethylene in the skin layer is 130 ℃ ~138 ℃, and that of polypropylene in the core layer is 165 ℃ ~170 ℃. If the temperature approaches the melting point of polyethylene, the surface polyethylene will begin to melt. At this time, the core polypropylene still retains its original morphology and physical properties. The staff finished the ES composite short fiber, placed it in the hot air box in the form of a net, and carried out temperature treatment under the condition of no pressure to ensure that the temperature reached the specified melting temperature of the surface polyethylene and the adhesion between the melting of various fibers. The adhesion formed can be local adhesion, or point or linear adhesion. Compared with other types of non woven fabrics, this type of non woven fabric has elasticity and excellent fluffy. In production, the non woven fabric with the characteristics of thin and low square meter weight can be obtained. After carding, the fibers mainly exist in the fiber web in a longitudinal arrangement, so the fracture of non woven fabrics has a large longitudinal strength, while the transverse strength is relatively small. The elongation at break is small in the longitudinal direction and large in the transverse direction. In addition, the fiber does not contain toxic and harmful substances. Through practice, it is found that it will not produce irritating reaction to the skin, but will produce antibacterial and bacteriostatic effects.

2.Application advantages of ES composite fiber in air through non woven production

The cost of ES composite fiber non woven fabric is relatively low. Its application in production has the effect of "core absorption and moisture permeability". With these advantages, it has been widely used, especially in the production of medical and health care products. As a new material, ES fiber has a very broad development prospect due to its low operation difficulty and no need to invest a lot of money. In the actual production process, the proportion of polypropylene (ethylene) fiber is light, the thermal conductivity is not high, and it can also prevent chemical corrosion and mold. The above features ensure the high quality of hot air production.

ES fiber

In conclusion, the application of ES composite fiber in the production of air through non woven can effectively improve product quality and avoid the impact of air through non woven production on the surrounding environment. In addition, ES fiber has the advantages of low cost and high efficiency. As the main material produced by enterprises, it can save enterprise expenses and provide consumers with fiber products with quality assurance.
