Hydrophilic cotton pad for skin care comprising two different external surfaces
The invention relates to a hydrophilic cotton pad for skin-care exhibiting a specific surface weight of at least 150 g/m 2 , and having two different outer sides of which the fibers are entangled. In the invention, the first outer side has hollow striae apart by a spacing s 1 between 1 and 8 mm and having a depth d of at least 0.25 mm and wherein at least 50% of the fibers are entangled. The pad of the invention is used to apply skin-care products, such as cosmetics, to the skin.
1. A hydrophilic cotton pad used for skin-care having a specific surface weight of at least 150 g/m 2 , comprising a first outer side and a second outer side which are different from each other and which each have fibers which are entangled, wherein the first outer side comprises hollow striae spaced apart by a spacing s 1 of between 1 and 8 mm and have a stria depth d of at least 0.25 mm, and wherein the pad has a tensile strength of at least 20 N in a direction of motion and at least 16 N in a direction transverse thereto.
2. A hydrophilic cotton pad for skin-care having a specific surface weight of at least 150 g/m 2 , comprising a first outer side and a second outer side which are different from each other and which each have fibers which are entangled, wherein the first outer side comprises hollow striae spaced apart by a spacing s 1 of between 1 and 8 mm and have a depth d of at least 0.25 mm, and wherein at least 50% of the fibers are entangled.
3. Pad as claimed in claim 1 or 2 , wherein the spacing s 1 between the striae of the first outer side is between 1.2 and 5.5 mm.
4. Pad as claimed in claim 1 or 2 , wherein the stria depth d of the first outer side is at least 0.40 mm.
5. Pad as claimed in claim 1 or 2 , wherein the tensile strength is at least 25 N in the direction of motion and at least 20 N in the direction transverse thereto.
6. Pad as claimed in claim 1 or 2 , wherein the second outer side comprises striae which are spaced apart by a spacing s 2 of between 0.4 and 1.2 mm.
7. Pad as claimed in claim 1 or 2 , wherein at least 60% of the fibers are entangled.
8. Pad as claimed in claim 1 or 2 , wherein the striae of the first outer side are continuous, discontinuous, or curved lines.
9. Pad as claimed in claim 1 or 2 , wherein the fibers are 100% cotton fibers.
10. Pad as claimed in claim 1 or 2 , wherein one of the first outer side or the second outer side comprises an imprint distinct from the striae.
11. Pad as claimed in claim 1 or 2 , wherein the first outer side includes an absorption retarding agent for aqueous products.
12. Pad as claimed in claim 11 , wherein the retarding agent is a composition based on a softener, or wax.
13. Pad as claimed in claim 12 , wherein the retarding agent is an emulsion of a natural wax, mineral-based wax, vegetal-based wax or an animal-based wax.
14. Pad as claimed in claim 13 , wherein the wax emulsion is a beeswax emulsion.
15. A method for manufacturing a hydrophilic cotton pad as claimed in claim 1 or 2 , wherein said method comprises providing a cotton lap, hydroentangling the first outer side of said lap using water jets having axes which are spaced apart by a spacing of between 1 and 5.5 mm and which have an applied energy of at least 1.4×10 −3 kwh/m 2 , and hydroentangling the second outer side of the lap using water jets having axes spaced apart by a spacing of between 0.4 and 1.2 mm and which have an applied energy of at least 0.9×10−3 kwh/m 2 .
16. A manufacturing method for a pad as claimed in claim 1 or 2 , wherein said method comprises providing at least two hydrophilic cotton laps based on bleached fibers conformed into laps or bleached laps, marking a first lap such that striae are formed spaced apart from each other by 1 to 8 mm and are at least 0.25 mm deep, wherein marking pressure is sufficient to impart to the pad a strength of at least 20 N in a direction of motion and 16 N in a direction transverse thereto, marking or consolidating the second lap, and combining the first lap and the second lap so processed wherein each side which has been marked and/or consolidated is situated at an outside of the pad.
17. Method for manufacturing a pad as claimed in claim 15 , further comprising applying an agent for retarding absorption of an aqueous product on the first outer side.
18. Method for manufacturing a pad as claimed in claim 16 , further comprising applying an agent for retarding absorption of an aqueous product on the first outer side.
19. Pad as claimed in claim 1 or 2 , wherein the first outer side serves to cleanse skin by putting a make-up remover or cleansing lotion on said pad, with the striae initially acting as product storage areas and then serving to collect impurities, and the second outer side serving to absorb excess product and impurities.
