Abstract
The invention provides a manufacturing method of side-leakproof absorbing articles. The manufacturing method is capable of manufacturing leakproof strips and compositing the leakproof strips to two transverse sides of an absorbing core and includes an absorbing core forming procedure and an upper and lower non-woven fabric wrapping procedure. A leakproof strip manufacturing procedure and a drawing procedure including compositing the leakproof strips to the two transverse sides of the upper surface of the absorbing core are performed between the absorbing core forming procedure and the upper and lower non-woven fabric wrapping procedure. The leakproof strip manufacturing procedure includes a blowing step of uniformly blowing water-absorbent resin onto hydrophilic material through a blower from top to bottom and a winding step of winding the hydrophilic material with water-absorbent resin into leakproof strips through a helical winding device. The drawing step includes clamping and conveying the leakproof strips continuously wound to the two transverse sides of the upper surface of the absorbing core through a pair of clamping and conveying wheels and compositing to the upper surface of the absorbing core.
Description
Technical field
The present invention relates to the making of hygienic article, be specifically related to a kind of manufacture method of anti-side leakage absorbing articles.
Background technology
Disposable adsorption object as baby paper diaper be known, it comprises the liquid permeability surface layer, absorber and the opaque liquid bottom that set gradually from top to bottom, described diaper have extend along waistline direction laterally and extended to back waist region direction by front waist region longitudinally, the front waist region of described diaper is positioned at opaque liquid bottom outside and is provided with frontal waist plaster, the both lateral sides that is positioned at back waist region is pasted along being provided with left and right waist, in the time that waist subsides in left and right are fixedly arranged on respectively frontal waist plaster both lateral sides, diaper can be fixed on wearer's waist and prevent from coming off.On the basis of this known baby paper diaper, the Chinese patent CN1290477C of December in 2006 bulletin on the 20th discloses a kind of manufacture method of disposable diapers, it is the improvement of doing on aforementioned known baby paper diaper basis by the prepared disposable diapers of the method, further, on June 15th, 2005, the Chinese patent CN1626050A of bulletin disclosed a kind of method and prepared article thereof of manufacturing pants type diaper, and this patent specification discloses the whole manufacture method of diaper in detail.Inventor, follow-up investigation is found, known various absorbing articles is in order to obtain good anti-side leakage effect, generally realize by lamellar pad being set in the surperficial both lateral sides of absorbent commodity, and in lamellar pad, be provided with the wire elastic material rods such as elastic leather strap, thereby the elasticity of utilizing elastic material rod erects lamellar pad and form a dike shape structure with Body contact, although this bank protection structure can play the effect of choked flow, but it only stops that by very thin pad absorption liquid is to side leakage, real absorber position still occurs with the form of plane, in the time that the factors such as the limb activity because of people make absorbent commodity and skin paste tightlyer, very thin lamellar pad pressurized can be adjacent on absorbent commodity surface, dike shape structure is disappeared, lose anti-side leakage function.
In order to overcome above-mentioned technical problem, as Fig. 1, inventor has developed a kind of anti-side leakage absorbent commodity, comprise the liquid permeability surface layer 1 setting gradually from top to bottom, absorber and opaque liquid bottom 3, the absorbent cores 23 that described absorber is wrapped up by upper strata non-woven fabrics 21 and lower floor's non-woven fabrics 22 forms, the both lateral sides of the upper surface of described absorbent cores 23 is respectively equipped with along the Leakproof strip 24 of absorbent cores 23 longitudinal extensions, the upper side of described each Leakproof strip 24 is fixedly connected with described upper strata non-woven fabrics 21, described Leakproof strip 24 is reeled and is formed by water wetted material layer, on water wetted material layer, be distributed with water-absorbing resins, the length of described Leakproof strip 24 is 50～90% of absorber length, be highly 3～10mm, width is 5～10mm, the upper side of Leakproof strip is fixedly connected with part transverse width with upper strata non-woven fabrics is 3～10mm.Above-mentioned this anti-side leakage absorbing articles is provided with Leakproof strip in the both lateral sides of absorbent cores, Leakproof strip can effectively absorb the liquid to side leakage, thereby effectively stop liquid to spread toward both sides, stop the phenomenon of side leakage to occur, but, up to the present not yet have a kind of method above-mentioned Leakproof strip can be made to molding and be compound to the both lateral sides of above-mentioned absorbent cores.
