METHOD FOR PRODUCING A LAMINAR PRODUCT
The invention relates to a method for producing a laminar product suitable for manufacturing external covers of sanitary towels and nappies, formed by a polymeric coating deposited over the surface of a non-woven fabric substrate, as well as to the laminar product obtained using said method. The method comprises the following steps: obtaining adhesive polymeric mixtures, feeding the mixtures, in a melted state, to a curtain-type applicator, coating the substrate with the adhesive polymeric mixtures, and winding the laminar product obtained. The product obtained comprises a polymeric coating bonded to the non-woven fabric substrate, wherein the polymeric coating consists of an adhesive polymeric layer that has a reduced thickness, ranging between 1 and 10 micra, said product being suitable for medical and personal hygiene applications.
ANTIMICROBIAL AND ANTIVIRAL HYGIENIC PRODUCTS
The present invention relates to hygienic products such as sanitary pads and tampons, patient/adult diapers and baby diapers which are made antimicrobial. In the present invention, a mixture of glucopon, chlorhexidine gluconate and triclosan is obtained from the boron compounds called sodium borate, zinc borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate; and this mixture provides antifungal, anticandidal, antibacterial and antiviral properties to the woven or non-woven textile products and hygienic products. Additionally, the said hygienic products are made hydrophilic by means of the invention.
Absorbent article with topsheet treated to reduce surfactant migration
An absorbent article having a liquid pervious topsheet wherein at least a portion of the topsheet has been treated to become hydrophobic; a backsheet joined to said topsheet; an absorbent core disposed between said topsheet and said backsheet, said absorbent core having an inner surface oriented toward the skin of the wearer when said absorbent article is being worn and an outer surface oriented toward the garment of the wearer when said absorbent article is being worn; and a surfactant applied to at least a portion of said outer surface of said topsheet wherein the topsheet has been treated hydrophobic and wherein the hydrophilic surfactant is added to the areas treated hydrophobic.
Absorbent article
Disclosed is an absorbent article comprising; (a) a topsheet having a skin facing side and a core facing side, the topsheet being liquid permeable and having the core facing side coated with at least about 0.01 mg/m.sup.2, preferably from about 0.05 mg/m.sup.2 to about 0.2 mg/m.sup.2, of calcium carbonate; (b) a backsheet which is liquid impermeable; and (c) an absorbent core comprising an absorbent material, the absorbent core disposed between the topsheet and the backsheet.
ABSORBENT ARTICLE WITH TOPSHEET TREATED TO REDUCE SURFACTANT MIGRATION
An absorbent article having a liquid pervious topsheet wherein at least a portion of the topsheet has been treated to become hydrophobic; a backsheet joined to said topsheet; an absorbent core disposed between said topsheet and said backsheet, said absorbent core having an inner surface oriented toward the skin of the wearer when said absorbent article is being worn and an outer surface oriented toward the garment of the wearer when said absorbent article is being worn; and a surfactant applied to at least a portion of said outer surface of said topsheet wherein the topsheet has been treated hydrophobic and wherein the hydrophilic surfactant is added to the areas treated hydrophobic.
ABSORBENT ARTICLE
Disclosed is an absorbent article comprising; (a) a topsheet having a skin facing side and a core facing side, the topsheet being liquid permeable and having the core facing side coated with at least about 0.01 mg/m.sup.2, preferably from about 0.05 mg/m.sup.2 to about 0.2 mg/m.sup.2, of calcium carbonate; (b) a backsheet which is liquid impermeable; and (c) an absorbent core comprising an absorbent material, the absorbent core disposed between the topsheet and the backsheet.
ABSORBENT ARTICLE WITH FUNCTION-FORMED TOPSHEET, AND METHOD FOR MANUFACTURING
An absorbent article in the form of a feminine hygiene pad is disclosed. The article includes a topsheet formed of a section of formed nonwoven web material having an ordered arrangement of zones, each zone comprising one or more attenuated regions adjacent to one or more built-up regions, wherein the attenuated regions have a first average basis weight and the built-up regions have a second average basis weight. Through configuration of the regions and the ordered arrangement, inclusion of melt additive to the resin(s) from which the filaments are spun and/or application of a surfactant to a surface of the topsheet, the topsheet may be imparted with a Rewet of no greater than 0.50 g and an Acquisition Time of no greater than 25 seconds, balancing competing topsheet performance characteristics in a manner acceptable or preferable for consumers/users.
APERTURED EXTRUSION COATED NONWOVEN WEB FOR ABSORBENT ARTICLES AND ABSORBENT ARTICLES INCLUDING SAME
An apertured extrusion coated nonwoven web for use as a topsheet in an absorbent article includes a nonwoven material having a user-facing side and a garment-facing side opposite the user-facing side. The nonwoven material includes a plurality of fibers. The apertured extrusion coated nonwoven web also includes a polymer coating on the garment-facing side of the nonwoven material, the polymer coating having a basis weight of about 2 gsm to about 6 gsm, and a plurality of three-dimensional apertures that extend through the nonwoven material and the polymer coating. Each of the plurality of three-dimensional apertures includes a continuous sidewall extending from a garment-facing side of the polymer coating. The apertured extrusion coated nonwoven web has an open area of greater than 5% when subjected to a pressure of 0.6 psi.
ABSORBENT ARTICLE WITH TOPSHEET TREATED TO REDUCE SURFACTANT MIGRATION
An absorbent article having a liquid pervious topsheet wherein at least a portion of the topsheet has been treated to become hydrophobic; a backsheet joined to said topsheet; an absorbent core disposed between said topsheet and said backsheet, said absorbent core having an inner surface oriented toward the skin of the wearer when said absorbent article is being worn and an outer surface oriented toward the garment of the wearer when said absorbent article is being worn; and a surfactant applied to at least a portion of said outer surface of said topsheet wherein the topsheet has been treated hydrophobic and wherein the hydrophilic surfactant is added to the areas treated hydrophobic.
ABSORBENT ARTICLE WITH FUNCTION-FORMED TOPSHEET, AND METHOD FOR MANUFACTURING
An absorbent article is disclosed. The article includes a topsheet formed of a section of formed nonwoven web material having an ordered arrangement of zones, each zone comprising one or more attenuated regions adjacent to one or more built-up regions, wherein the attenuated regions have a first average basis weight and the built-up regions have a second average basis weight, wherein the first average basis weight is less than the second average basis weight, the difference in basis weights corresponding to disposition of the filaments according to the ordered arrangement. The attenuated region(s) may be included within a configuration of one or more channel portions on the topsheet. Alternatively or in combination, the attenuated region(s) may be included within a hinge portion extending along a wing portion of the topsheet.
