摘要： A thermoplastic elastomer-based multifilament yarn and a method of making a thermoplastic elastomer-based multifilament yarn are disclosed. The multifilament yarn comprises a first filament that is at least partially adhered to a second filament. The first filament and the second filament are each formed from a thermoplastic elastomer composition comprising a thermoplastic elastomer that exhibits a flexural modulus of about 300 MPa or less as determined in accordance with ISO 178:2019 at a temperature of about 23° C. The yarn has a linear density of from about 1 to about 500 denier per filament and exhibits an elongation at break of about 300% or more as determined in accordance with ASTM D2653-07 (2018) at a temperature of about 23° C.

摘要： Resorbable implants, coverings and receptacles 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 molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.

摘要： Disclosed are fibers comprising one or more branded fibers which exhibit surface markings in a repeated pattern along the length of the branded fibers. The branded fibers can be incorporated into yarns or fiber bands to represent supply chain information of the yarns, fiber bands, and/or articles made from the yards or fiber bands. In a specific example, branded fibers can be incorporated into an acetate tow band. The branded fibers can be recovered from a cigarette filter, the repeated pattern decoded, and supply chain information associated with the acetate tow used to make the cigarette filter, such as manufacturer, customer, ship to location, and even the acetate tow bale, can be obtained.

摘要： A process for forming a nanofiber non-woven includes mixing a first and second thermoplastic polymer and a plurality of particles, then subjecting the mixture to elongational forces when the first and second polymers are in a softened condition forming nanofibers of the first polymer. Next, the mixture is brought to a condition where the temperature is below the softening temperature of the first polymer forming a first intermediate. The first intermediate is consolidated forming the second intermediate where at least 70% of the nanofibers are fused to other nanofibers. Next, at least a portion of the second polymer is removed and at least 50% of the particles are positioned adjacent a surface of the nanofibers.
