1. Characteristics of ES fiber
1.1 Common raw materials for production
Es fiber uses very common raw materials, mainly polyethylene (pe), polypropylene (pp), polyester (pet) and so on.
1.2 The production method is simple
The production method of ES fiber is similar to that of ordinary polyester staple fiber, mainly based on the "two-step method" of "melt spinning + hot drawing", and some manufacturers also have the "one-step method" of "melt spinning and drawing".
1.3 Features of use
The biggest development feature of ES fiber is that the melting temperature of a cortical structure material is lower than that of the core material, which is an ideal raw material for making hot-air non-woven fabrics and hot-rolled non-woven fabrics.
2. Application of ES fiber
2.1 Hot air and hot rolling non-woven fabric
Comb the ES fibers into a cotton web, and use hot air to melt the skin or hot-roll the skin at a certain temperature (> higher than the melting temperature of the skin material, but lower than the melting temperature of the core material); therefore, at the fiber winding point, the melting The skin layers adhere to each other, leaving the unmelted core intact. Play the role of "skeleton". This special self-adhesive method completely eliminates the use of chemical adhesives and greatly reduces the damage to cotton webs caused by mechanical bonding. The molded products are characterized by fluffy, soft, breathable, non-toxic and non-irritating. It is very suitable for the manufacture of hygiene products such as feminine sanitary napkins and diapers.
2.2 Other uses
Es fiber can also be used in clothing linings, automotive interiors, filter materials, packaging materials, cushions and other product fields.
