4533 results about "Wrinkle skin" patented technology

A wrinkle, also known as a rhytide, is a fold, ridge or crease in the skin or on fabric. Skin wrinkles typically appear as a result of aging processes such as glycation, habitual sleeping positions, loss of body mass, or temporarily, as the result of prolonged immersion in water.

Method for manufacture of minimum porosity, wrinkle free composite parts

A process and associated apparatus used to prepare a thermoplastic composite from a plurality of plies of thermoplastic resin prepregs. The prepregs are formed into a composite structure under two chambers; a rigid outer chamber (of any convenient size or shape) and a second flexible inner chamber containing a prepreg lay-up. The absolute pressures are reduced concurrently in a stepwise method in both chambers. This concurrent, stepped pressure reduction is accomplished at a rate which prevents the vacuum bag from moving far from the prepregs, and prevents wrinkles from forming in the prepregs. Pinching off the diffusion paths required for the removal of unwanted gases is eliminated. The lay-up is then heated and the absolute pressure in the outer rigid chamber is increased. This pressure constrains the flexible inner chamber during out-gassing of the thermoplastic resin, preventing wrinkles from forming in the prepregs. The absolute pressure in the outer rigid chamber is increased to atmospheric pressure or greater causing the prepregs to consolidate. A low absolute pressure is maintained in the flexible inner chamber. The temperature is then increased to the cure temperature of the resin and held for a time sufficient for the resin to cure. The resulting consolidated thermoplastic resin is substantially void free and detectable wrinkles are absent.

Methods for improving the performance of fabric wrinkle control compositions

The present invention provides methods for improving the performance of a consumer wrinkle control composition by making the composition available to the consumer and providing information to the consumer concerning the use of the composition to control wrinkles in fabrics without the application of heat. Information may be provided by teaching educational elements and disseminating educational elements to consumers in an efficient, effective, and affordable manner as well as techniques for heightening consumer awareness of the product. The information that is provided to the consumer may concerns the use of the composition to remove or control wrinkles in fabrics without the application of heat, instructions for the proper use of the product, the product's effectiveness, the appearance of the fabric in the finished state after treatment, how the product can be incorporated into the consumer's everyday habits and lifestyles, additional non-wrinkle related benefits that may be achieved with the product and how the composition can be effectively and safely used by most members of the consumer's household. Also provided are methods for prolonging or extending the useful life of fabric items that require frequent and repeated laundering processes and that are prone to cause incremental damage to fabric fibers. The useful life of such fabric items is prolonged by enabling the item to be revitalized or renewed for rewear without laundering, thus reducing the number of launderings and the resulting damage to fabric fibers over a given period of time.
