Provided is a beauty care pack including a release film and a beauty care sheet which is separably attached to the release film, wherein the beauty care sheet comprises: a support; a fiber layer which is laminated on the support and in which water-soluble polymers are formed in the form of a nanofiber web; a moisturizing layer which is laminated on the fiber layer and consists of the water-soluble polymers and moisturizing materials; and a beauty care layer which is laminated on the moisturizing layer and in which the water-soluble polymers and functional materials are formed in the form of a nanofiber web, such that active ingredients are absorbed into the skin while being dissolved by moisture.
摘要:
The present invention is to provide an antiviral substance effective for inactivating viruses, a fiber product carrying the antiviral substance, and a fiber structure. The antiviral substance comprises a polymer containing a maleic acid component as a monomer unit in its polymer chain, and is effective against an avian influenza virus. An antiviral fiber can be produced by mixing the copolymer with cellulose and spinning the resulting mixture.

A plexifilamentary strand of film-fibrils having a tensile strength of at least 1 gpd and a surface area, measured by the BET nitrogen adsorption method, greater than 2 m2/g. The film-fibrils are comprised of at least 20 % by weight of polyethylene and polypropylene, wherein the polyethylene and polypropylene each comprise at least 5 % by weight of each of the film-fibrils. A process for the production of such a strand is also provided that includes the steps of forming a spin solution of polyethylene and polypropylene polymers in a solvent and spinning the spin solution at a pressure that is greater than the autogenous pressure of the spin solution into a region of substantially lower pressure and at a temperature at least 50 °C higher than the atmospheric boiling point of the solvent.
摘要:
A thermoplastic resin composition comprising a thermoplastic resin (A) and a thermoplastic polymer (B) having a glass transition temperature within the range of from -20°C to 70°C which are melt-blended in a proportion (A)/(B) of from 95/5 to 20/80 in weight ratio. The composition, upon application of an external stress in a temperature region of from a temperature about the glass transition temperature of the thermoplastic polymer (B) to the melting point thereof, is transformable to any shape that conforms to that stress, and is capable of becoming fixed to the transformed shape in a temperature region lower than the glass transition temperature. The composition can be used to provide a temperature-dependent shape-transformable/fixable product formed of the above composition.
