摘要:
The present invention relates to a method for manufacturing a protein fiber, including an extension and contraction step of contracting or extending a protein raw fiber containing a protein by bringing the protein raw fiber into contact with a liquid or vapor; and a drying step of drying the protein raw fiber that has undergone the extension and contraction step while adjusting a length of the protein raw fiber to an arbitrary length.

Disclosed is a polyamide fiber having a degree of orientation equal to or higher than 0.7 and equal to or lower than 0.85. The polyamide fiber is suitably obtained by forming a polyamide component having high moisture absorbency and a specific soluble component into a conjugated fiber under specific fiber formation conditions.

Provided are: a homogeneous fiber board which has small variation in weight per square meter; and a method of the same. The present fiber board (100) is obtained by: mixing a vegetable fiber (1) (such as kenaf fiber) and a thermoplastic resin fiber (such as polypropylene fiber) to form a web; forming a fiber mat by needle punch method or the like to interlace the fibers that constitute the web; and heating and compressing the fiber mat. The vegetable fiber is crimped in advance by stirring a raw material fiber in presence of water. The present production method has: a web-forming process wherein a web is formed by mixing a vegetable fiber and a thermoplastic resin fiber; a mat-forming process wherein a fiber mat is formed by interlacing the fibers that constitute the web; and a board-forming process wherein a fiber board is formed by compressing the fiber mat with heating.

A bulked yarn comprising a bulked single spun yarn obtainable from a composite twisted yarn in which a single spun yarn and a water-soluble yarn together in a direction opposite to the twisting direction of the single spun yarn by dissolving and removing the water-soluble yarn in a hydrophilic solvent from the composite twisted yarn is prepared. When the bulked yarn with a length of 100 cm is hung down in a state where both ends of the yarn are fixed at a distance of 10 cm from each other in a direction perpendicular to the direction of gravitational force, twisting does not occur or an average value of the distances from the uppermost end of a twisting section to the first and second fixed ends of the yarn is 30 cm or more. The bulked yarn has excellent texture, lightweight properties, and anti-pilling properties, as well as excellent weaving and knitting properties and productivity. Further, a woven or knit fabric comprising the bulked yarn is more lightweight, more voluminous, softer with an excellent touch, and better in heat-insulating properties and air permeability, has greater anti-pilling properties, sheds no fluff, and has better rapid-drying properties despite having great water absorbency.

Disclosed are a functional sheet including a first substrate applied or impregnated with an active ingredient, which is to be used in low temperature water at 0°C to 30 °C, wherein the active ingredient is to be physically or chemically adsorbed on a second substrate in the low temperature water, and remain on the second substrate after removal of the low temperature water, as the first substrate, a substrate having a water contact angle of 90°or less is used so that 70% or more of the active ingredient applied or impregnated to the first substrate can be released in the low temperature water at 0 °C to 30 °C within 5 minutes; and another functional sheet including a first substrate applied or impregnated with an active ingredient, which is to be used in low temperature water at 0 °C to 30 °C, wherein the active ingredient is to be physically or chemically adsorbed on a second substrate in the low temperature water, and remain on the second substrate after removal of the low temperature water, the functional sheet has light transmittance of 2 to 20%, so that 70% or more of the active ingredient applied or impregnated to the first substrate can be released in the low temperature water at 0 °C to 30 °C within 5 minutes.
摘要:
The invention relates to a resorbable, surgical suture material that has been thermally treated with steam and is based on polyglycolic acid and/or a lactide copolymer. Said material degrades rapidly and has a rapidly decreasing knot-rupture force in 'in vivo' conditions and a high initial knot-rupture force in relation to the rapid degradation.

A method of manufacturing an isotropic pitch-based carbon fiber spun yarn fabric includes the following steps of: obtaining composite yarn by winding a water-soluble polymer fiber around a surface of isotropic pitch-based carbon fiber spun yarn; obtaining a composite yarn fabric by weaving the composite yarn; and obtaining the isotropic pitch-based carbon fiber spun yarn fabric by dissolving and removing the water-soluble polymer fiber from the composite yarn fabric.
摘要:
A polyglycolic acid resin is used as a forming aid to efficiently produce various shapes, such as porous film, ultrafine fiber, ultrafine film and porous hollow fiber, of shaped products of substantially water-insoluble thermoplastic resins. More specifically, a shaped composite of the polyglycolic acid resin and the substantially water-insoluble thermoplastic resin is caused to contact an aqueous medium, thereby selectively removing the polyglycolic acid resin through solvolysis and extraction to leave a shaped product of the remaining thermoplastic resin. A glycolic acid aqueous produced by the solvolysis and extraction can be recycled into the polyglycolic acid resin as a forming aid via the formation of a concentrated glycolic acid oligomer and glycolide.
