ES fiber is a sheath-core composite fiber obtained by successfully combining low-melting components and high-melting components on a single fiber. It has excellent thermal bonding properties. The low melting point component in ES fiber melts under heat treatment conditions higher than its melting point, and bond with other materials to form a binder-free environmentally and friendly non-woven fabric. ES fiber has various advantages such as soft, fluffy, low-temperature processing, heat-bonding, plasticity, non-toxic, non-irritating, and lightweight. It is mainly used to manufacture high-quality sanitary products such as sanitary napkins and diapers. And it is also high-quality materials used to make medical products such as medical protective cloth and medical protective masks, and so on. There are two main types of ES fibers. The first kind is a composite of PE and PP. Its sheath layer is PE (polyethylene, melting point 130�°C), and its core layer is PP (polypropylene, melting point 165�°C). The second kind is a composite of PE and PE. Its sheath layer is PE, and the core layer is PET (polyester, melting point 255â??), which is an upgraded version of PE/PP. ES is divided into EP and ET in terms of material and functionally divided into the hydrophilic, water-repellent, hydrophilic, and weak parent, single parent, multi-parent.In addition, it also can be divided into whitening, general whitening, high holding, medium holding, and low holding. The specifications are 1.5D38mm, 2D38mm, 4D51mm, and so on. In the future, the trend will gradually develop towards fine deniers.
