Diaper Raw Materials

Topark Råmateriale

Topsheet Råmateriale refererer til det øverste lag ble råmateriale, også kendt som dæklaget eller overfladelaget. Dette lag er placeret inde i bleen, tæt på barnets hud, og kommer i direkte kontakt med urin. Designet af Topsheet har til formål at holde det tørt og give en blød overflade for at sikre babyens komfort.

The raw material for the Topsheet is typically a non-woven fabric, which is a thin and uniform material made from fibers or a combination of fibers and adhesives. This material is breathable, allowing air circulation to reduce the feeling of dampness on the skin. At the same time, it needs to have certain liquid permeation resistance properties to prevent urine from penetrating into the layers beneath, keeping the top layer relatively dry.

The performance and quality of Topsheet Raw Material directly impact the comfort and absorption performance of the diaper. Therefore, in diaper manufacturing, choosing and using high-quality Topsheet materials that meet safety standards is crucial.
