  • the absorbent fabric is mainly used for the fields of indoor bath towels, bathrobes, bathing suits, sport towels, children clothes and the like.
  • Raw materials adopted currently are mainly classified into two categories: the first category is obtained by looping treatment of a knitting machine by means of natural hydrophilic property of fabric fibers such as cotton, linen and the like, so as to produce an appearance with a pile of loops, and the processing field is knitting industry; and the second category is to increase an absorbent area using chemical fibers with specially-shaped cross section to enhance absorbent performance, and the processing fields are the knitting industry and tatting industry.
  • the absorbent fabric obtained by the above two categories of raw materials has a certain absorbent effect, but has apparent defects.
  • the fabric of plant fibers has good absorbent effect, but has problems of easy color fading, non-resistance to washing, easy abrasion, poor dimensional stability and the like, thereby increasing use cost and reducing quality, while the chemical fibers with specially-shaped cross section have a certain absorbent effect, but are not combined with water through a hydrophilic group of the fibers, and a contact area with water molecules is increased through a specially-shaped cross section structure (non-circular structure) of the chemical fibers with specially-shaped cross section so as to achieve the absorbent effect.
