TH18348B - Processing of materials To improve the handling of viscous fluids - Google Patents

Abstract

DC60 (07/10/40) What was revealed is the improved structure that includes the fiber plates. Non-woven treated with substances Changes in viscosity properties are included when a fluid with a viscous elasticity comes into contact with the fiber sheet. Has been processed and will change. Security features Viscous, elastic fluid And promotes the absorption, mobility and distribution of fluids throughout the structure of the adsorbent material to change the desirable viscosity properties, namely alkyl poly glycosides. Especially those with 8 to 10 carbon atoms in the alkyl chain. When used to provide a volume of The solids that were added of approximately 0.1% to approximately 5.0% compared to the dry weight of the nonwovens may result in rapid absorption, portability and dispersion. Change substance Other elastic viscosity properties It has also been disclosed. The process may be effective in high solid content mixtures using conventional application equipment such as an aerosol coating and other equipment. Similar or in the picture Internal additives The absorbent structure is especially useful as a component of the dispersion layer of sanitary napkins. For absorbing menstruation Including other products Used to handle blood, for example surgical masks What was revealed is the improved structure that includes the fibers.

Claims (23)

1. A structure adapted to accommodate elastic fluids. This structure consists of a synthetic substrate with an elastic-viscosity altering agent placed on its surface. This allows the elastic fluid to come into contact with it, thus affecting the material properties and elastic viscosity of the fluid. 2. The structure of Claim 1, in which the synthetic support material consists of a film. 3. The structure of Claim 1, in which the synthetic backing material is a non-woven fiber sheet that is naturally hydrophobic. 4. The structure of claim 3, in which the substance alters viscosity and elasticity properties, consists of oligosaccharides. 5. The structure of the second claim, in which the non-woven fabric consists of spunbond fibers that are a polymer of propylene. 6. The structure of claim 3, in which the substance alters the viscosity-elastic properties, is an alkyl polyglycoside with 8 to 10 carbon atoms, alkyl chain. 7. The structure of claim 6, which includes the non-woven fabric, consists of spunbond non-woven fabric. 8. The structure of claim 6 involves the presence of a substance that alters the viscosity and elasticity properties in an amount ranging from approximately 0.1 to approximately 5 percent as a solid addition relative to the dry weight of the nonwoven fabric. 9. Personal hygiene products consisting of a liquid-impermeable backing, absorbent material, and body contact material, where the body contact material consists of a structure as per claim 8. 10. Personal hygiene products under claim 9 that are menstrual absorbent devices. 11. Menstrual absorbent device under Patent 10 in the form of a sanitary napkin, the structure of which consists of a fluid dispersion layer of the sanitary napkin. 12. Personal hygiene products under claim 9 that are fecal collection devices. 13. Personal hygiene products under claim 12, which are disposable diapers, the structure of which consists of a diaper lining. 14. Personal hygiene products under claim 12 that are incontinence care products. 15. The structure of claim 6, in which the said non-woven fabric sheet consists of spunbond fibers that are a polymer of propylene. 16. Personal hygiene products consist of an impermeable back pad, an absorbent material, and a body contact layer, the body contact layer of which consists of a structure as described in Claim 6. 17. Personal hygiene products under claim 16 that are fecal collection devices. 18. Personal hygiene products under claim 17, which are disposable diapers, the structure of which consists of a diaper sheet. 19. Personal hygiene products under claim 17 that are incontinence care products. 20. Personal hygiene products under claim 16 that are menstrual absorbent devices. 21. Menstrual absorbent device of claim 20 in the form of a sanitary napkin, the structure of which consists of a fluid dispersion layer of the sanitary napkin. 22. A sanitary pad consists of a cover layer, a backing layer, and an absorbent material sandwiched between the cover layer and the backing layer. The fluid-distributing layer contains a viscosity-modifying agent in an amount sufficient to provide optimal flexibility between the cover layer and the absorbent material at the point of contact with menstrual blood. 23. The adsorption process of an elastic viscous fluid consists of a step of contact between the elastic viscous fluid and a support material containing a substance that modifies the elastic viscosity properties in an amount that produces the desired effect.
