The width ratio for stating first expanding layer and the second expanding layer is 1:1；First expanding layer and the second expanding layer are inhaled by flexibility
Water cellulose is made, and the flexibility water-absorption fiber includes 43% viscose rayon fibers, 30% polypropylene and 27% xanthan gum grafted propylene
Acid-acrylamide copolymer.
5. a kind of baby's diaper as claimed in claim 4, it is characterised in that：The flexibility water-absorption fiber passes through following steps
It is prepared,
Step 1：1 part of xanthan gum is weighed, is added suitable deionized water, xanthan gum solution by volume after stirring and dissolving：Propylene
Acid solution=1:2.5 the acrylic acid solution that degree of neutralization is 85% is added into xanthan gum solution, stirs after having into mixed solution
Acrylic acid solution by volume：Acrylamide solution=1:1, acrylamide solution is added into mixed solution；
Step 2：Mixed solution is heated to 70 DEG C, according to volume ratio mixed solution：Crosslinking agent=1:0.05, crosslinking agent N, N- is added
Methylene-bisacrylamide keeps 70 DEG C of constant temperature stirring 1h；
Step 3：85 DEG C are heated to, according to volume ratio crosslinking agent：Initiator=1:1 into solution be added initiator potassium persulfate it is molten
Liquid, continue 85 DEG C of stirring 2h of constant temperature after reaction was completed；
Step 4：By product volume ratio water：Methanol=1:4 detergent washing several times, is put into 60 DEG C of vacuum ovens and does
Xanthan gum grafted propylene acid-acrylamide copolymer is made in dry 12h.
