Description
Technical field
The invention belongs to textile technology fields, and in particular to a kind of superabsorbent water composite fibre and preparation method thereof.
Background technique
Disposable sanitary articles such as sanitary napkin, paper diaper, incontinence pad etc. have water absorption rate to core water-absorbent material used
Fastly, the general character of reverse osmosis does not require high, absorption speed.
Sanitary napkin, water-absorbent material used in paper diaper are Time of Fluff Slurry and/or high hydroscopic resin particle such as polyacrylic acid at present
Its water absorption rate (pure water) of ester, especially polyacrylate type resin has a disadvantage in that absorption speed is undesirable up to hundreds times,
Its water imbibition is easily influenced by the ion in water, if its multiplying power for absorbing physiological saline only has 40~60 times, in normal use shape
Under state, the extremely full state such as urine, blood of saliferous is drawn, it is 5 minutes time-consuming or more, and also waterishlogged resin is by external force pressure
Afterwards, it is easy to return infiltration, it in use, can be to skin maceration so as to cause discomfort；Time of Fluff Slurry is that have the preparation of natural wood pulp fiber,
Water absorbent rate is lower than 10 times, easily returns infiltration.In general, multi-purpose using Time of Fluff Slurry as carrier, addition water-absorbing resin is disposably defended as aforementioned
The water absorption layer of raw articles.
The novel absorbent material for developing more preferable performance is target that industry is pursued jointly.
Mainly there are alginate dressing, interactive dressing and hydrophilic dressing to severe sepage wound wet union dressing at present
Deng, respectively there are advantage and disadvantage, alginate dressing meets body fluid into gel, and high water absorption also high moisturizing discharges calcium ion, promote Wound healing,
Disadvantage is that its gelation and water absorption are related to the total amount of sodium ion in body fluid, sodium ion and potassium ion supply amount in body fluid
In the case where limited, it is difficult to the performance advantage of alginates high water absorption is given full play to, and hydrophilic dressing and interactive dressing all exist
It is only used for quickly absorbing sepage, effective component cannot be discharged to wound to promote to heal.
Chitin is the product made from the natural materials, has good affinity to raw body, is suitable as skin trauma
Protection materials have a large amount of hydrophilic radical (carboxyl, hydroxyl, acetyl group) in strand, therefore chitin has parent well
Aqueous and rehydration, chitin have the characteristics that water absorption is big, absorption speed is fast, water-retaining property is strong, and alginic acid through calcium ion or
The calcium alginate or alginic acid zinc that zinc ion is cross-linked to form meet potassium, sodium ion etc. into gel, discharge calcium ion or zinc ion, water suction
Amount is big, and water holding capacity is strong, and the complex fiber material that the two combines not only had had high-hydroscopicity energy, but also has needed for promoting wound healing
The effective components such as calcium, zinc, be the ideal of ideal disposable sanitary articles such as sanitary napkin, paper diaper and Medical dressing etc.
Use material.Both simultaneously compound and it can be easier to realize fiber feasibility prepared with chitin.
But pure chitin or the spinning solution of chitosan preparation need to be existed using high-purity organic solvent as solidification liquid
Dehydration setting rate is slow, to be not easy into fibre, the fibre strength of preparation is low, and subsequent weaving is difficult, technology difficulty and higher cost
Etc. features.
