A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in at least a portion of the surface thereof, an electroconductive section having a surface electrical resistivity of 10.sup.11 Ω/cm.sup.2 or less, or a hydrophilic section having a water contact angle of preferably from 15° to 90° at 25° C. A user collects, with the fiber collection tool, a fiber spun by the user by electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.

A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in its interior, an electroconductive section. Preferably, the fiber collection tool further includes a surface section outside the electroconductive section. In a fiber deposit production method, a user collects, with the fiber collection tool, a fiber spun by the user by performing electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.

The present disclosure provides methods and compositions for directed to synthetic block copolymer proteins, expression constructs for their secretion, recombinant microorganisms for their production, and synthetic fibers (including advantageously, microfibers) comprising these proteins that recapitulate many properties of natural silk. The recombinant microorganisms can be used for the commercial production of silk-like fibers.

Disclosed is a medical material manufactured using collagen and a method of manufacturing the same. The method includes (1) preparing collagen using distilled water as a solvent, (2) filling a syringe with the prepared collagen and then spinning the collagen through a syringe needle, (3) immediately immersing the spun collagen in a cross-linking solution, which is a mixture including therein a hyperosmotic agent and a cross-linking agent mixed with each other, (4) removing and then washing the collagen after cross-linking is completed, and (5) removing and then drying the collagen after the washing is completed. When the collagen is spun and processed into the form of a thread and the spun thread is then cross-linked, the cross-linked collagen thread has increased strength compared to before cross-linking, and the shape thereof is retained in an aqueous solution.

The present disclosure relates to polymer resins, fibers, and yarns with permanent antimicrobial activity, and a method of producing the same. In one embodiment, the antimicrobial polymer resin comprises a polymer having less than 2500 ppm of zinc dispersed within the polymer, less than 1000 ppm of phosphorus, wherein the weight ratio of zinc to phosphorus is at least 1.3:1 or less than 0.64:1.

The invention relates to a process for manufacturing a multilayer knitted textile by heating a multi-layer knitted textile in the presence of one or more dye compounds, wherein the multilayer knitted textile comprises a fabric outer layer and a fabric inner layer, wherein the fabric outer layer is knit from a first yarn containing a combination of modacrylic fibers and cotton fibers, wherein the fabric inner layer is knit from a second yarn made from 50-90% HBA/HNA filaments, wherein the heating shrinks the outer layer from about 5 to 25% in length, width, or both.

A mucoadhesive solid or semisolid ocular delivery systems that includes a matrix of preactivated thiomers, preferably under the form of ocular inserts or ocular films. The ocular delivery systems are useful for ocular drug delivery for the treatment of ocular diseases. The delivery systems of the invention can also be used for alleviating ocular conditions such as dry eye syndrome.

The method to produce a packaged cosmetic product comprises a step of feeding a support film along a feed path, a step of forming a membrane substrate, and a step of packaging the membrane substrate. The method can be implemented by means of a suitable apparatus, which comprises a station for feeding the support film, a station for forming the membrane substrate, and a packaging unit, which are disposed in succession along the feed path of the support film.

The present disclosure discloses a high-whiteness polyimide microfiber and a preparation method thereof and use. The polyimide fiber includes polyimide obtained from the reaction of wholly alicyclic dianhydride HTDA and an aromatic diamine monomer containing methyl or trifluoromethyl by chemical imidization. In the present disclosure, the polyimide microfiber has both excellent heat-resistant stability and spinning film-forming property, and the fabric has ultra-high whiteness. The microfiber fabric prepared from the polyimide fiber may be used as a component with high-temperature resistant and high-whiteness in personal protective equipment such as mask and protective clothing, and also may be used as an electronic component in the high-tech field such as aerospace, optoelectronic, microelectronic and automobile.
