A method for making jeans. A material is weaved for use as a front portion of the jeans. The warp portion of the weave is spun with a combination of open-end and ring spinning. The weft portion of the weave is spun with open-end spinning. The resulting weaved material is then sulfur dyed, singed and pre-shrunk to form the front portion. Another material is weaved for use as a back portion of the jeans using a fabric composition which is 79% cotton, 20% filament fiber polyester, 1% spandex. The warp portion of the weave is spun using a combination of open-end and ring spinning. The weft portion of the weave is made from the filament fiber polyester. The resulting fabric composition weaved material is then indigo dyed and singed and then pre-shrunk to form the back portion. The two portions are cut and sewed together to produce the jeans. | ||||||

PURPOSE:To obtain a contact lens uniformly colored and free from color unevenness and also free e.g. from decoloring even in washing and boiling treatments, etc. CONSTITUTION:A soluble vat dye is dissolved in a monomer which can dissolve the vat dye. Then, the monomer containing the dissolved vat dye is mixed with another monomer and the monomer mixture is polymerized. Subsequently, the reactional product is processed into a contact lens-shape to obtain the objective colored contact lens. | ||||||

The invention concerns a method of tinting the iris area of a hydrogel soft contact lens (21) to produce a pattern. The area (15) to be tinted is exposed to a vat dye in a predominantly aqueous, liquid, solution through a stencil pattern on a screen (12) so that the dye is absorbed only into the unmasked areas of the lens and the dye is then developed. The screen mask is a flat screen material and during tinting the normally curved lens is adhered to the first side of the screen by surface tension in a flat disposition, with the dye solution applied gently in drops (22) to the other side of the screen, such that the dye is absorbed in a non-solid pattern into the iris area of the lens. The invention is particularly applicable to low (38 % to 50 %) water content lenses. | ||||||

L'invention concerne un procédé permettant de teindre la zone de l'iris d'une lentille souple à base d'hydrogel (21) afin de créer un motif. La zone à teindre (15) est exposée à un colorant de cuve dans une solution liquide principalement aqueuse au moyen d'un cache disposé sur un tamis (12) de manière que le colorant ne soit absorbé que dans les parties non masquées de la lentille, après quoi la lentille est soumise au developpement. Le cache à tamis est une étoffe plane et pendant la teinture la lentille normalement courbe adhère au premier côté du tamis grâce à la tension superficielle en position plane, la solution de colorant étant appliquée doucement goutte par goutte (22) à l'autre côté du tamis, de manière que le colorant soit absorbé avec un motif non solide dans la zone de l'iris de la lentille. L'invention s'applique tout particulièrement aux lentilles à faible teneur en eau (de 38 à 50 %). | ||||||

Process for the treatment of tanned or non-tanned products comprising skins, leathers or other collagen-containing sheet materials, at different stages in their transformation. According to the process, the products are placed in contact at (1) with a pressurized dense fluid, for example pressurized CO2 in a supercritical or liquid state, which optionally contains one or more active substances and is brought to a pressure Pi at (5) and to a temperature Ti at (7), either for the removal of grease from said products if pure fluid is used, or for their impregnation with active substances such as tanning, reinforcing, dyeing or water-repellent agents. After impregnation or degreasing, the products are brought to ambient pressure for removal of the dense fluid. The process can be carried out at several stages in the transformation of skins into leathers or other sheet materials, fluid pressure and temperature characteristics being adapted to the purpose of the invention. | ||||||

L'invention concerne un procédé de traitement de produits constitués par des peaux, des cuirs ou d'autres matériaux en feuilles contenant du collagène, tannés ou non, à différents stades de leur transformation. Selon ce procédé, on met en contact en (1) les produits avec un fluide dense sous pression, par exemple du CO2 à l'état supercritique ou liquide sous pression, qui contient éventuellement une ou plusieurs substances actives et qui est porté à une pression Pi en (5) et à une température Ti en (7), soit pour dégraisser ces produits lorsqu'on utilise du fluide pur, soit pour les imprégner de substances actives telles que des agents de tannage, de renforcement, de coloration ou d'hydrofugation. Après cette imprégnation ou ce dégraissage, on ramène les produits à la pression atmosphérique pour éliminer de ceux-ci, le fluide dense. Le procédé peut être mis en oeuvre dans plusieurs stades d'une chaîne de transformation des peaux en cuirs ou autres matériaux en feuilles, les caractéristiques de pression et de température de fluide étant adaptées à l'objectif visé. | ||||||
