To wrap a hygienic fleece consisting of a cotton wool web in fluff-proof form without the need for a separate nonwoven material, synthetic fiber is added to the starting material in a quantity sufficient for thermoplastic consolidation of the surface and a surface of the prepared cotton wool web is consolidated to give a nonwoven finish. A calender comprising at least one heating embossing roller is used.

Fluff free tampon and method for making

A method for absorbing bodily secretions while hindering the generation of odors and growth of microbes comprising applying a fibrous mass having copper cations bound through selected anions, preferably carboxymethyl, the amount of chemically bound copper being between 0.1 and 3% by weight. The fibrous mass can be in the form of a catamenial device, bandage, diaper, shoe liner, or the like.

Microbistatic and deodorizing catamenial and hygienic devices

This invention affords catamenial devices such as tampons and panty liners in which a microbistatic fibrous material is layered or covered with a non-microbistatic fibrous material.

Layered catamenial device

A tampon for feminine hygiene consists of a cylindrically-compressed length of a strip of cottonwool or rayon staple or a combination thereof which is wrapped with an overlap in a fluff-free or fuzz free covering material, said strip being cut into the required lengths together with the covering material perpendicularly to the overlap line, and a recovery thread attached to the length of a strip of cottonwool or rayon staple or a combination thereof. The problem which the invention solves is to prevent fibers from breaking loose from the exposed cut edges. According to the invention, the exposed cut edges are folded onto the surface of the length of a strip of cottonwool or rayon staple or a combination thereof after it has been separated and compression is carried out in such a way that the exposed cut edges are situated inside the tampon.

Tampon for feminine hygiene and a process for its production

A modified fibrous material comprising cellulose fibers substituted at their cellulose anhydroglucose units by anionic moieties of at least one of the formulae: --PO.sub.3 H.sup.(-) ; --(CH.sub.2).sub.n -PO.sub.3 H.sup.(-) ; --(CH.sub.2).sub.n -SO.sub.3.sup.(-) ; or (CH.sub.2).sub.n --COO.sup.(-) ; where n is from 1 to 3; and capped by copper cations to the extent that said cellulose fibers bind from about 0.1 to about 3.0% by weight of copper, based on the weight of said fibers; as well as processes for its production.

Copper-modified carboxyalkyl-cellulose fiber

A cellulose fiber which is carboxyalkylated in free acid form, a fiber mass formed therefrom, and a method for producing such fiber.

pH-regulating Cellulose fiber

Hygienic products of various types, all comprising as their operative body contact portion a fiber mass of acidic, modified, pH-regulating, cellulose.

pH-regulating Cellulose products

A tampon or suppository insertion applicator comprising an insertion sleeve and an injection slide whose insertable length is not greater than that of the sleeve and which has means for preventing further insertion at one end.

Insertion applicator

This invention is directed to sanitary hygiene products. More particularly, this invention is directed to sanitary hygiene products for the absorption of secretions containing urine and/or blood which contains in an absorption layer an odor-preventing amount of one or more esters of citric acid and/or acetylcitric acid with aliphatic alcohols with from 1 to 6 carbon atoms or alicyclic alcohols with from 4 to 6 carbon atoms, as an odor-preventing substance.

Sanitary hygiene products having odor-preventing properties

A blank useful in the production of a tampon for feminine hygiene consist of a length of cottonwool or rayon staple or combination of it strip wrapped in a moisture-pervious, fluff-free covering material. According to the invention, a covering material consisting at least partly of thermoplastic fibers is used and is sealed at its exposed edges to enclose the length of cottonwool strip in a fluffproof form.
