A method for the treatment of spider silk filament for use as a thread or composition in the manufacture of cosmetic, medical, textile, and industrial applications, wherein the spider silk filament, derived from genetically modified organisms, is treated with at least one component selected from the group consisting of vitamins, hormones, antioxidants, chelating agents, antibiotics, preserving agents, fragrances, dyes, pigments, magnetic nanoparticles, nanocrystals, cell adhesion enhancers, thermal insulators, shrinkage agents and cosmetic, medical or dermatological active substances. Textile fabrics obtained by this method are stronger, bio-compatible, bio-degradable and have a higher thermal conductivity. Treated spider silk filament can also be applied in an oil-in-water or water-in-oil protective cream that is hypoallergenic and ensures a firmer skin.

A process for making a coated curved article comprises the steps of: A) providing a curved article having an alignment layer onto which a solution of a polymerizable liquid crystal composition is applied and B) curing the polymerizable liquid crystal composition. Step A) involves A1) providing the curved article having the alignment layer and spray coating or dip coating the solution onto the alignment layer or A2) co-extrusion of the curved article having the alignment layer and the solution of the polymerizable liquid crystal composition. The curved article is preferably a fiber or a car window.
摘要:
A self-retaining suture comprises a filament. The filament has retainers on the surface such that the filament can engage and retain tissue without knots. The filament comprises one or more materials at least one of which is a shape-memory polymer or shape-memory alloy. The shape-memory material is used to cause the shape of the retainers and or the filament to transition from a first configuration to a second configuration in response to a transition stimulus. The transition stimulus may be applied before, during, or after deployment of the suture in tissue. In particular, the shape-memory material may be used to enhance the formation, elevation and/or deployment of the retainers. Methods for manufacturing the filament and retainers are also described.

The invention relates to a method for treating surfaces. Said method is characterised in that the surfaces are treated with (a) at least one hydrophobic agent, (b) at least one cross-linked organic copolymer in a particle form, (c) at least one film-forming copolymer comprising epoxide groups, NH-CH 2 OH-groups or acetoacetyl groups, (d) optionally, one or several emulsifiers, and finally, dried after treating.

Verfahren zur Behandlung von Oberflächen, dadurch gekennzeichnet, dass man die Oberfläche behandelt mit (a) mindestens einem Hydrophobiermittel, (b) mindestens einem vernetzten organischen Copolymer in partikulärer Form, (c) mindestens einem filmbildendem Copolymerisat mit Epoxidgruppen, NH-CH 2 OH-Gruppen oder Acetoacetylgruppen, (d) gegebenenfalls einem oder mehreren Emulgatoren, und im Anschluss an die Behandlung trocknet.
摘要:
An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.
摘要:
The present invention relates to a production method of a textile (fabric) which is electrically conductive, fire-retardant, thermally stable and also has thermal absorption properties as well as the electromagnetic wave shielding properties wherein the monomer of conductive polymer is polymerized on the textile after the inorganic particles which are restrained into the latex as core-shell are impregnated into the textile and thus fixed, and to a device which operates in accordance with this method.
摘要:
The present invention relates to a functionalized textile substrate with cyclodextrins and/or cyclodextrin derivatives and water- and/or oil-repellent agents, which combines the water- and/or oil-repellent functionality with odor-absorbing properties.
