The present invention relates to a method for manufacturing gold thread with no drawing-induced inconsistency, and gold thread manufactured by the method, wherein: gold thread is manufactured by spirally twisting together a plurality of gold rods, each having a relatively smaller thickness than the prior art gold rod, whereby the gold thread ensures sufficient rigidity, and thus inconsistency of the gold thread, induced by drawing of gold, can be eliminated; and the gold thread formed by spirally twisting together a plurality of gold rods has an increased surface area, as compared to the conventional gold thread having the same diameter, and thus can alleviate skin aging and improve antibacterial properties by increasing the frictional force with the skin.

The present disclosure relates to the field of textiles, and in particular, to a multifunctional temperature-adaptable yarn, and a preparation method and use thereof. A multifunctional temperature-adaptable yarn is prepared from 20-30% of a temperature-adaptable fiber, 20-30% of an antibacterial fiber, and 40-60% of a cotton fiber in mass percentage by blending. The cotton fiber is a short fiber having a length of 10-50 cm. The multifunctional temperature-adaptable yarn has a linear density of 18-45 tex, a single yarn breaking strength of 12.5-12.8 cN/tex, a single yarn breaking strength coefficient of variation (Cv) of 11.5-12.5%, and a coefficient of variation of mass (CVm) of 11.3-11.4%. The multifunctional temperature-adaptable yarn in the present disclosure is made by blending three types of fibers and thus enabled to have good antibacterial and temperature adaptation properties.

An antibacterial twisted yarn including a first fiber and a second fiber having a shorter length than the first fiber and twisted together with the first fiber, wherein at least one of the first fiber and the second fiber includes a piezoelectric fiber that generates a charge by application of external energy.

Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing, and the fibers may be oriented. Coverings and receptacles made from forms of poly(butylene succinate) and copolymers thereof have also been developed for use with cardiac rhythm management devices and other implantable devices. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings and receptacles are made from meshes, webs, lattices, non-wovens, films, fibers, and foams, and contain antibiotics such as rifampin and minocycline.

A filter that includes a plurality of fibers arranged to form a first principal surface and a second principal surface opposite the first principal surface, and a plurality of first piezoelectric fibers that generate negative charges by stretching are arranged at least on a side of the first principal surface.

A deodorant and antibacterial copper nanofiber yarn and a manufacturing method thereof are provided, the manufacturing method including: providing a raw material, including a polyblend slurry, a nano-metal solution, a plurality of inorganic particles, and a plurality of TPU rubber particles; stirring the raw material into a mixed material; making second metal contact the first metal ion fiber to cause the first metal ion to undergo a reduction reaction to obtain a first metal nanoparticle; drying the mixed material; performing hot-melt spinning on the mixed material, the plurality of TPU rubber particles, after being hot-melted, being coated on an outer peripheral side of the spun wire to form a first-phase wire; forcibly cooling the first-phase wire; stretching the first-phase wire; air-cooling the first-phase wire to form a second-phase wire; and collecting the second-phase wire to make the wire into a finished deodorant and antibacterial copper nanofiber yarn.

An antibacterial yarn that includes a core yarn including a functional polymer that generates a charge by external energy and a first sheath yarn higher in hygroscopicity than the core yarn, the first sheath yarn covering at least a part of a periphery of the core yarn across an axial direction of the core yarn.

A basketball net includes a multi-layer cord including each of an outer layer formed of a first antimicrobial, moisture wicking fiber and an inner layer including a second antimicrobial, moisture wicking fiber. The outer layer is woven from a first antimicrobial, moisture wicking yarn to form a wall that defines a central opening, and at least one cord is located within the central opening, the at least one cord formed by a second antimicrobial, moisture wicking yarn. The at least one cord includes a plurality of cords including a first cord formed by the second antimicrobial, moisture wicking yarn and a second cord including a third antimicrobial, moisture wicking yarn. The plurality of cords includes: the first cord; the second cord including the third antimicrobial, moisture wicking yarn and at least one monofiber yarn; and a third cord formed by a plurality of mono fiber yarns.

An antibacterial fiber that includes a charge generation member shaped in a fibrous form and that generates charges sufficient to suppress the proliferation of a bacillus by input of external energy, and a water-resistant member that covers the charge generation member.

The invention relates to a method for producing an antimicrobial fabric or yarn, said method comprising the steps of immersing a fabric or yarn in an aqueous solution of a metal salt while simultaneously subjecting said solution to ultrasonic radiation; and removing the fabric or yarn from said solution and subsequently converting the metal salt in situ in the fabric or yarn into metal oxide nanoparticles, preferably via chemical and heat treatment. Fabrics and yarns obtained or obtainable by such method are also provided. In a further aspect the invention provides an apparatus for performing such method.
