Description
Technical field
The present invention relates to textile technology field, specifically a kind of SAF superabsorbent water baby's diaper hot-wind nonwoven cloth
Preparation process.
Background technique
Baby's diaper needs indispensable performance to seek to the water absorbing capacity for having high as far as possible, while guaranteeing its water lock again
Performance prevents its reverse osmosis when being pressurized from coming out.In addition, the material of baby's diaper should have good skin-friendly, prevent pair
Baby's skin damages.
And the material of baby's diaper mainly uses ES staple fiber hot wind cloth and super moisture absorbing resin (SAP) on the market now,
Although it solves paper diaper water absorption issue, poor air permeability, and existing diaper fibrous raw material mostly uses greatly chemistry
Substance, Long Term Contact infant skin will lead to red swelling of the skin and itch, or even fester.
Superabsorbent fiber (superabsorbentfiber, SAF) is grown up after super moisture absorbing resin (SAP)
Specific function fiber, water absorbent rate ratio are conventionally synthesized that fiber is several ten times larger or hundred times, even higher, additionally have water conservation
The features such as property number, humidity absorption and release is good, easy to process, can be applied to the fields such as wet diaper medical material.
ES staple fiber is the abbreviation of English " Ethylene-Propylene Side By Side ", is Japanese Chisso Corporation
The one kind for the noticeable polyolefin series fiber that developed.As a kind of novel thermal bonding composite fibre, ES fiber
Very high evaluation is obtained in the world.ES fiber after Overheating Treatment, fiber and fiber mutually then, can be formed do not have to it is viscous
The non-woven fabrics formed body of mixture.Existing main non-woven fabrics processing method, e.g., hot rolling formula, hot air type, aculeus type, wet type, air-laid
Net formula, spun lacing formula can use ES fiber, select different heat treatment modes, can get the non-woven fabrics of different-effect, such as:
Hot blast adhesion formula obtains bulky nonwoven fabric；Hot calendering bonding formula obtains high-intensitive non-woven fabrics.ES fiber series has extensive
Adaptability is processed, existing main non-woven fabrics processing method can use ES fiber.
Summary of the invention
The purpose of the present invention is reinforced by combing and hot wind using superabsorbent fiber, bamboo fibre, hydrophilic ES fiber as raw material
The water suction of exploitation, water conservation, respiratory be good, antibacterial bacteriostatic hot wind product.
To achieve the above object, a kind of preparation process of SAF superabsorbent water baby's diaper hot-wind nonwoven cloth is designed, it is special
Sign is, includes the following steps:
(1) smart shredding mixing: by 3~5wt% superabsorbent fiber SAF, 5% bamboo fibre and 90~92% hydrophilic ES it is fine
The dimension interior preliminary shredding of progress of investment cotton feeding box together；The preliminary mixed composite fibre of shredding is transported in blending box by blower
It is finely mixed, then is transported to feeding hopper through the blower；Feeding hopper equably feeds fine mixed fiber basis weight
Carding machine, the output speed 31-33g/min of feeding hopper；
(2), prepare single layer fibre net: the mixed fiber of smart shredding is sufficiently combed into single layer fibre net by carding machine, single
Layer web is transported to next procedure, the speed 1080r/min-1100r/min of carding machine, the working roll of carding machine by doffer
Speed 29.5-85r/min；
(3), the single layer fibre net of carding machine output the mixed and disorderly lapping of fiber: is subjected to mixed and disorderly lapping, control lapping machine feeding
With the speed of output, required web caliper, width and grammes per square metre are obtained；The web completed is continuously fed into lower road work by lapping machine
Sequence；
(4), drying: the fibre web completed is entered into baking oven and carries out hot wind reinforcing, 133-136.5 DEG C of oven temperature, drying is fast
Spend 45m/min；
(5), wind: the product come out from baking oven carries out trimming by winder, and fixed length is cut, in rolls.
The present invention compared with the existing technology, using the different mixing proportion of functional fiber SAF and ES fiber, bamboo fibre,
Substantially increase antibiotic property；And the water absorbing properties excellent using superabsorbent fiber, substantially improve the water imbibition of hot-wind nonwoven cloth
Can, water imbibition is 5-10 times of traditional hot wind cloth；SAF pulp freeness is bigger, good water-retaining property, rate of water absorption faster, greatly
The water retention property of hot-wind nonwoven cloth, and soft patch skin are improved greatly；The product networking uniformity is preferable；The hot wind cloth of superabsorbent water
As the wick layer of diaper, skin-friendly and safety are had more than tradition macromolecule resin.
