Abstract

Shoe sole inserts for eliminating foot odours are comprised of loofah fibres, active carbon and a binder such as a butadiene-acrylonitrile latex binder. The compsn. may also contain jute fibres. The prods. are made e.g. by mixing the loofah fibres, jute fibres, active carbon and butadiene acrylonitrile latex binder with water in a beater mixer to form a paste, casting the paste onto a conveyor which conveys it onto a heated drum, and calendering the dried prod.. The prods. are soft, have rapid absorption and desorption of water vapour, are rot-proof and have excellent odour eliminating properties.

Description

L'invention a pour objet un produit composite pour la fabrication de semelles éliminant les odeurs et un procédé pour la fabrication de ce produit. Ce produit est constitué en combinaison par des fibres de loofah, par du charbon actif et par un liant. The subject of the invention is a composite product for the manufacture of soles eliminating odors and a process for the manufacture of this product. This product is made in combination by loofah fibers, activated carbon and a binder.

Les fibres de loofah entourent les graines d'une cucurbitacée appelée communément éponge du Japon" et elles entrent dans la composition du produit revendiqué en raison de leurs qualités d'absorption rapide et importante de l'humidité, de désorption très rapide, d'imputrescibilité et de légèreté. The fibers of loofah surround the seeds of a cucurbitaceae commonly called sponge of Japan "and they enter into the composition of the product claimed because of their qualities of fast and important absorption of moisture, very fast desorption, rot-proof and lightness.

Le charbon actif peut avoir diverses provenances, sous réserve d'être primitivement pulvérulent; et c'est ainsi qu'il peut provenir de noix de coco calcinées, activées physiquement à la vapeur d'eau; il entre dans la composition du produit revendiqué pour ses qualités d'adsorption des odeurs
Quant au liant qui constitue le troisième composant essentiel du produit, il s'agit avantageusement d'un latex du type butadiène-acrylonitrile; ses effets sont de donner au produit une cohésion suffisante, sans altérer les effets des fibres de loofah et du charbon actif.Activated carbon can come from a variety of sources, provided it is originally powdery; and this is how it can come from calcined coconuts, physically activated by steam; it is part of the composition of the claimed product for its odor-absorbing qualities
As for the binder which constitutes the third essential component of the product, it is advantageously a latex of the butadiene-acrylonitrile type; its effects are to give the product sufficient cohesion, without altering the effects of loofah fibers and activated carbon.

A ces trois composants essentiéls ; fibres de loofah, charbon actif et liant, est éventuellement ajoutée une charge complémentaire destinée à augmenter le volume du produit et à abaisser son prix de revient. Cette charge complémentaire est avantageusement constituée par des fibres de jute. De telles fibres peuvent, par exemple, provenir de plantes herbacées des pays tropicaux, par exemple de la région du Bengale. To these three essential components; loofah fibers, activated carbon and binder, is optionally added an additional charge intended to increase the volume of the product and lower its cost price. This additional filler is advantageously constituted by jute fibers. Such fibers can, for example, come from herbaceous plants of tropical countries, for example from the Bengal region.

A titre d'exemple non limitatif est ci-après indiquée la composition qualitative et quantitative d'un produit composite convenant particulièrement bien à la confection de semelles
fibres de loofah ................ 50 %
fibres de jute ......................... 20 %
charbon actif ................... 25 %
latex du type butadiène-acrylonitrile.. 5 %
La fabrication d'un tel produit composite peut etre réalisée par mise en oeuvre d'un procédé selon lequel les fibres de loofah , les fibres de jute, le charbon actif à l'état pulvérulent et le latex du type butadièneacrylonitrile sont mis en suspension dans de l'eau, a raison par exemple de 1 kg de mélange des quatre composants précités pour 1000 litres d'eau.By way of nonlimiting example is indicated below the qualitative and quantitative composition of a composite product which is particularly suitable for making soles.
loofah fibers ................ 50%
jute fibers ......................... 20%
activated carbon ................... 25%
latex of the butadiene-acrylonitrile type. 5%
The manufacture of such a composite product can be carried out by implementing a process according to which the loofah fibers, the jute fibers, the activated carbon in the pulverulent state and the latex of the butadiene acrylonitrile type are suspended in water, for example 1 kg of mixture of the four components mentioned above per 1000 liters of water.

L'ensemble est malaxé,par exemple dans un mélangeur a battoirs, jusqu'à l'obtention d'une pâte ayant une assez basse viscosité. Cette pâte est ensuite étalée sur un convoyeur au moyen d'une couleuse doseuse; et ce convoyeur transfère le produit sur un tambour qui est chauffé par la vapeur ou par un fluide thermique pour réaliser le sèchage du produit. Après sèchage, le produit est calandré sur un cylindre lisse.  The whole is kneaded, for example in a mixer with beaters, until a paste having a fairly low viscosity is obtained. This paste is then spread on a conveyor by means of a dosing machine; and this conveyor transfers the product to a drum which is heated by steam or by a thermal fluid to carry out the drying of the product. After drying, the product is calendered on a smooth cylinder.
