A method for producing a balloon for a balloon catheter includes providing the balloon that has an outer surface. A solution including a solvent and a polymer is used to deposit the polymer onto the surface and form a surface coating of the polymer.

Provided are: polyurethane elastic fibers that achieve heat resistance, adhesiveness, and reelability and that are suitable for a gather member; a winding body therefor; a gather member; and a sanitary material. The present invention relates to: polyurethane elastic fibers that are multifilaments and that contain urethane bonds and urea bonds, the polyurethane elastic fibers being characterized in that the ratio of the urea bonds with respect to the urethane bonds is 0.05 to 5%; a winding body of said polyurethane elastic fibers, wherein the elongation rate of the polyurethane elastic fibers on the winding body is 0.05 to 10%; a gather member; and a sanitary material.

A hyaluronic acid facial mask, a preparation method therefor and a use method therefor is provided. The facial mask includes a substrate layer, a hyaluronic acid layer and a protective paper layer sequentially arranged. The hyaluronic acid layer is made of hyaluronic acid nanofibers. The hyaluronic acid nanofibers are formed by spinning a hyaluronic acid composite using an electrospinning method. The hyaluronic acid composite includes a dispersed phase and a solvent phase. The dispersed phase includes, in terms of mass percentage content, 70-95% of hyaluronic acid. The solvent phase includes water. The preparation method includes: spinning the hyaluronic acid composite on the substrate layer using an electrospinning method to form a hyaluronic acid layer, and then attaching the protective paper layer on the hyaluronic acid layer.

An artificial blood vessel is used, which alternatingly has, in an extending direction D2 of a weft yarn 2, a first region in which a warp yarn 1 and the weft yarn 2 are woven in a plain weave, a second region having a first portion on the second region side R21 in which the warp yarn 1 crosses over a plurality of weft yarns 2 and a second portion on the second region side R22 in which the warp yarn 1 extends so as to cross over one weft yarn 2, and a third region having a first portion on the third region side R31 in which the warp yarn 1 crosses over a plurality of warp yarns 2 and a second portion on the third region side R32 in which the warp yarn 1 extends so as to cross over one weft yarn 2.

Nonwoven fabrics may be fashioned as topical delivery systems with increased and controllable rate of product release, while still possessing the requisite strength and durability for mass production and distribution. Such delivery systems comprise fabrics that are fashioned from micro-denier fibers that are produced by fibrillating bicomponent island-in-the-sea fibers. Facial masks made from these fabrics can achieve adequate product delivery in 3-5 minutes or less.

A polymeric material fiber includes a polymeric material which is a homopolymer of caprolactone or a copolymer of at least 90% by weight of caprolactone and one or more additional monomers. An implantable mesh includes this fiber alone or combined with one or more additional fiber materials. Methods for treating patients involve implanting the fiber material, for example incorporated in a mesh.

Disclosed herein are methods of producing a cartilaginous implant by producing a polymer scaffold composition by electrospinning a polymer solution onto a collector in order to obtain polymer fibers; crosslinking the polymer fibers; and adding a plurality of cells to the polymer scaffold composition, wherein the plurality of cells comprises cartilaginous cells to form a cartilaginous implant.

The invention concerns a cosmetic patch product comprising a membrane substrate suitable to be absorbed by the skin, made up of at least one electrospun fiber based on a biocompatible polymer material, as well as a cosmetic article that comprises the same cosmetic patch product on a support base.

An elastomeric bicomponent fiber, including at least one sheath and a core, with non-blocking properties and a garment-like feel is provided. The core includes two or more polypropylene based elastomers and a secondary amide, and the sheath includes a non-elastomeric polyethylene. Further, the sheath can be present as a small portion of the total elastomeric composition, and the secondary amide can be present as a small portion of the core, while forming a bicomponent fiber with non-blocking properties and a garment-like feel, while maintaining good strength characteristics.

Provided is a spinning solution, comprising a cannabidiol powder and an alginate solution. Besides, the present invention further provides an alginate fiber comprising cannabidiol, and the preparation method and the use thereof. The cannabidiol powder in the spinning solution can be evenly dispersed in the alginate solution, so that the spinning solution of the present invention can be applied to wet spinning to form the alginate fiber comprising cannabidiol. The alginate fiber comprising cannabidiol has anti-oxidative, anti-bacterial, antiinflammatory, and anti-allergic abilities.
