Abstract
The utility model discloses one and refuse water-hydrophilic nonwoven cloth, comprise and refuse water finish fiber and hydrophilic finish fiber; Describedly refuse water finish fiber and hydrophilic finish fiber is skin-core structure, skin-core structure comprises cortex and sandwich layer, and the cortex by melting between sandwich layer is interconnected.The utility model is produced with the method that the fiber with hydrophilic finish is penetrated by hot blast after mixing by having the fiber refusing water finish, liquid rotating can be moved to guide layer and absorber rapidly by the passage of hydrophilic fibers composition, the existence simultaneously refusing water cellulose can effectively stop liquid to return from absorber to ooze to surface, thus reaches the result of surface dry.This design can overcome existing Through-Air Thermal Bonded Nonwovens liquid and return the problem of oozing the surface of sanitary humidity caused.Enforcement of the present utility model is by using blast heater heating to realize containing refusing water finish and the skin-core structure containing hydrophilic finish or core shift structural fibers, is a kind of production method of novel Through-Air Thermal Bonded Nonwovens.
Description
Technical field
The utility model relates to a kind of non-weaving cloth, particularly relates to one and refuses water-hydrophilic nonwoven cloth.
Background technology
Thermal non-woven fabric has been widely used in feminine hygiene and baby paper diaper, usually top layer is applied in, it can absorb rapidly body fluid (menstruation exudate, urine), and it is imported as far as possible uniformly the absorber of its lower floor, like this, both maintain skin dry and comfortable, prevent again the lateral leakage of body fluid.
Through-Air Thermal Bonded Nonwovens is the one in thermal bonding technology, and it is due to soft, fluffy and user can be made to feel comfortably cool and be widely used in personal hygiene nursing materials.Through-Air Thermal Bonded Nonwovens adopts the bicomponent fiber of parallel construction or skin-core structure, by hot air composite fibre after carding, cortex PE melting in composite fibre makes fiber overlap mutually, eventually passes cooling and becomes the non-weaving cloth having certain strength and extension property.
At present, worldwide hot blast nonwovens process raw materials mainly contains the bicomponent fibers such as PP/PE, PET/PE, the needs of fiber post processing substantially also just in order to meet its fibre process, to use demand but not more concerns of consumer.But for the designer of sanitary napkin, urine pants, owing to being subject to the impact of Through-Air Thermal Bonded Nonwovens infiltration rate and absorber uptake, how by improving, product is dry-ness has become design requirement problems faced.And consumer demand point is also more and more higher, therefore by improving some performance of fiber, making fiber meet characteristic in a certain respect, becoming the innovative point that designer is new, the demand meeting user that also can be higher.
Utility model content
Water-hydrophilic nonwoven cloth is refused for the utility model that solves the problem provides one.With adding through refusing the fiber of water finish process, the non-weaving cloth produced through specific manufacture craft has the performance well preventing from liquid from returning oozing, and the surface layer being used in sanitary napkin or urine pants can effectively improve the dry-ness of health product.
For reaching above-mentioned technique effect, the technical solution of the utility model is:
One refuses water-hydrophilic nonwoven cloth, comprises and refuses water finish fiber and hydrophilic finish fiber; Describedly refuse water finish fiber and hydrophilic finish fiber is skin-core structure, skin-core structure comprises cortex and sandwich layer, and the cortex by melting between sandwich layer is interconnected; The fibre fineness of refusing water finish fiber and hydrophilic finish fiber is 1 ~ 15Dtex, and length is 1 ~ 80mm; Refuse water finish fiber and hydrophilic finish fiber is interconnected to form fiber web, described in refuse water-hydrophilic nonwoven cloth and comprise double layer fibre net, the thickness refusing water-hydrophilic nonwoven cloth is 0.1 ~ 3.0mm.
Further improvement, described in refuse water finish fiber and hydrophilic finish fiber fibre fineness be 1 ~ 6Dtex, length is 30 ~ 60mm; The thickness of described non-weaving cloth is 0.5 ~ 2.0mm.
Further improvement, described in refuse water-hydrophilic nonwoven cloth cloth cover on carry out groove and embossed.
The utility model is produced with the method that the fiber with hydrophilic finish is penetrated by hot blast after mixing by having the fiber refusing water finish, liquid rotating can be moved to guide layer and absorber rapidly by the passage of hydrophilic fibers composition, the existence simultaneously refusing water cellulose can effectively stop liquid to return from absorber to ooze to surface, thus reaches the result of surface dry.This design can overcome existing Through-Air Thermal Bonded Nonwovens liquid and return the problem of oozing the surface of sanitary humidity caused.Enforcement of the present utility model is by using blast heater heating to realize containing refusing water finish and the skin-core structure containing hydrophilic finish or core shift structural fibers, is a kind of production method of novel Through-Air Thermal Bonded Nonwovens.
Advantage of the present utility model:
1, the utility model use terylene-polyethylene composite fibre or polypropylene fibre-polyethylene composite fibre, the polyethylene (PE) of cortex is different with the percent thermal shrinkage of sandwich layer terylene (PET) or polypropylene fibre (PP), be sticked together through hot-blast stove melting compared with the polyethylene (PE) of low melting point, in this process, fiber has occurred that distortion makes product have good fluffy sense.
2, due to the existence of hydrophilic fibers, the non-weaving cloth that the procedure of fibre production used by the utility model goes out has good liquid single penetration capacity, rapidly liquid rotating can be moved to guide layer and absorber.
3, due to the existence of hydrophilic fibers, the non-weaving cloth that the procedure of fibre production used by the utility model goes out has good liquid barrier ability, can effectively place liquid and be transferred to surface from absorber.
