Production process of ES short fiber non-woven fabric
Raw material preparation: Prepare ES fiber short fibers in proportion, which are composed of polyethylene and polypropylene and have the characteristics of low melting point and high melting point.
Web formation: The fibers are combed into a mesh structure through mechanical combing or airflow.
Hot rolling bonding: Using a hot rolling mill to heat and press the fiber web, causing the fibers to melt and bond together at high temperatures, forming non-woven fabric. The hot rolling temperature is generally controlled between 100 and 150 degrees, depending on the softening temperature and melting temperature of the fibers.
Winding and finished product inspection: Roll the hot-rolled non-woven fabric and conduct sampling and testing according to product quality standards, including physical indicators and appearance quality.
What are the characteristics of ES short fiber non-woven fabric?
We all know that ES short fiber non-woven fabric is a highly uniform non-woven fabric made from ultra short chemical fibers through wet papermaking process. It can be widely used in the manufacturing of battery separators, filter materials, non-woven wallpaper, agricultural film, tea bags, traditional Chinese medicine bags, shielding materials and other fields. ES short fiber non-woven fabric is a commonly used raw material for non-woven fabrics and has a wide range of applications. Next, let’s take a look at the characteristics and related applications of ES short fiber non-woven fabric.
ES short fiber non-woven fabric is a two-component composite fiber with a skin core structure. The skin structure has a low melting point and good flexibility, while the core structure has a high melting point and high strength. After heat treatment, a part of the skin layer of this fiber melts and acts as a bonding agent, while the rest remains in the fiber state and has the characteristic of low thermal shrinkage rate. This fiber is particularly suitable for producing sanitary materials, insulation fillers, filter materials, and other products through hot air infiltration technology.
Application of ES short fiber non-woven fabric
1. Short fiber non-woven fabric is an ideal thermal bonding fiber, mainly used for thermal bonding processing of non-woven fabrics. When the coarse combed fiber web is thermally bonded through hot rolling or hot air infiltration, the low melting point components form a melt bond at the fiber intersections. However, after cooling, the fibers outside the intersections remain in their original state, which is a form of “point bonding” rather than “belt bonding”. Therefore, the product has the characteristics of fluffiness, softness, high strength, oil absorption, and blood sucking. In recent years, the rapid development of thermal bonding methods relies entirely on these new synthetic fiber materials.
2. After mixing short fiber non-woven fabric and PP fiber, the es short fiber non-woven fabric is cross-linked and bonded through needle punching or thermal bonding. The advantage of this method is that it does not use adhesives or lining fabrics.
3. After mixing short fiber non-woven fabric with natural fibers, artificial fibers, and pulp, wet non-woven fabric processing technology can greatly improve the strength of non-woven fabric.
4. Short fiber non-woven fabric can also be used for hydroentanglement. After hydraulic puncture, the fiber webs intertwine with each other. When drying, the fibers curl instead of melting and bonding, twisting together to form non-woven fabrics with stretchability.
5. ES short fiber non-woven fabric has a wide range of applications. Widely used as a covering material for hygiene products. ES short fiber non-woven fabric is soft, low temperature processable, and lightweight, making it an ideal material for manufacturing a series of sanitary products such as women’s sanitary napkins and diapers.
With the further opening up of our country and the improvement of people’s living standards, the grade of sanitary products is gradually increasing. The use of non-woven fabrics with a high proportion of ES short fiber non-woven fabrics is an inevitable trend in this market. ES short fiber non-woven fabric can also be used for carpets, car wall materials and padding, cotton tires, health mattresses, filtration materials, insulation materials, gardening and home materials, hard fiberboard, adsorption materials, and packaging materials.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
