After the ES fiber is heat-treated, part of the cortex melts and combines, and the rest remains in the fiber state, which has the characteristics of small heat shrinkage. The fiber is especially suitable for the hot air infiltration process to produce hygienic materials, such as diapers, non-woven fabrics, sanitary napkins, warm filling materials, filter materials and other products. The prospect of demand for ES optical fiber is getting brighter and brighter. It is the main raw material for hot-rolled air-through non-woven fabrics. At present, there is a lot of room for improvement in baby diapers and medical diapers, especially diapers, for air-through non-woven fabrics.
