Denier fiber can bring splendid smooth effect, so face layer is tended not to using fine count fiber, therefore current paper diaper product
Face layer skin-friendly is also to be further improved.
3) for paper diaper, designer still considers not enough wearing off for paper diaper on convenience, since paper is urinated
Trousers lack the high component of identification, when consumer, especially young father or the elderly wear paper diaper to baby, it is easy to wear
Instead.
Therefore, the performance etc. of the absorbent articles such as existing paper diaper remains to be further improved.
