Method for thermal molding of filament product
Provided is a thermal molding method for producing a thermally molded article having excellent abrasion resistance at its melt-fused part. Polyamide 6 and a copolyester are prepared separately. The copolyester contains terephthalic acid, ethylene glycol, and 1,4-butanediol as copolymerization units. The copolyester may further contain -caprolactone and/or diethylene glycol as a copolymerization unit. A multifilament yarn in which core-sheath type composite filaments each containing a core component and a sheath component at a ratio of 1 to 4:1 by mass are bundled is produced by a composite melt-spinning method using the polyamide 6 as the core component and the copolyester as the sheath component. Using the multifilament yarn, a product of filaments is produced by weaving, knitting, knitting and braiding, or braiding. The product of filaments is heated to melt the copolyester and fuse the core-sheath type composite filaments to each other while retaining the initial filament form of the polyamide 6, thus thermally molding the product of filaments.
Skin weft and method for manufacturing the same
A skin weft with artificial hair attached thereto to provide various styling options or ample volumetric feeling. The skin weft comprises a stitched portion formed by stitching on a side edge of artificial hair composed of human hair or resin hair, a resin tape welded to a surface of the stitched portion, and a bonding component attached to a surface of the resin tape. The method for manufacturing the skin weft comprises the steps of forming a stitched portion by stitching one side edge of human hair or resin hair arranged and conveyed in the form of a sheet, and supplying a resin tape onto a surface of the stitched portion to form a bonding portion. Automatic mass production is achieved, thereby improving productivity and significantly reducing manufacturing costs. Additional means are unnecessary in the manufacturing process, thereby enabling an unskilled person to perform the task.
Internal trim part, comprising a decorative skin having a decorative element that is arranged in a depression in the decorative skin and is connected to the decorative skin by means of ultrasonic welding, and method for producing said internal trim part with decorative element
The present invention relates to an internal trim part for a vehicle, comprising at least two layers. A decorative skin (1) forms an upper layer and has a depression (3), in which a decorative element (8) is arranged. The decorative element (8) is connected to the decorative skin (1) by means of a bonded connection, such as a weld seam, in particular an ultrasonic weld seam (16). The invention further relates to a method for producing an internal trim part and to a device for performing said method.
METHOD FOR MANUFACTURING A FITTING COMPONENT FOR PERSONAL FALL PROTECTION EQUIPMENT
The invention relates to a method for manufacturing a fitting component for personal fall protection equipment including the steps of winding a fiber to form a plurality of windings, and covering the fiber with a plastic, in such a manner that the fitting component is obtained and, corresponding to the core of the windings, an opening in the fitting component is obtained.
Spiral unit, insertion apparatus, and manufacturing method of spiral unit
A spiral unit includes a base tube extended along a longitudinal axis and made of a first thermoplastic resin, and a fin disposed on an outer peripheral surface of the base tube along a fin axis spirally extended around the longitudinal axis and made of a second thermoplastic resin. The fin includes a strip portion provided in a state of being bonded to the outer peripheral surface of the base tube and spirally extended along the fin axis. The second resin being mixed with a magnetic material in the strip portion.
STRIP LINED CATHETERS AND METHODS FOR CONSTRUCTING AND PROCESSING STRIP LINED CATHETERS
Apparatus and methods are provided for making one or more tubular components of medical catheters or other tubular bodies using a strip of polymer material including a length, a width, and a first surface including a lubricious or other coating or surface modification. The strip is directed adjacent an elongate mandrel, such as beading, such that the length of the strip extends along the mandrel and the coating is disposed towards the mandrel. The strip is rolled at least partially around the mandrel such that the coating or surface modification is disposed inwardly towards the mandrel, and one or more strip-constrainment members are wrapped around the rolled strip. The directing, rolling, and wrapping steps may be substantially continuous to create one or more strip-mandrel-constrainment member subassemblies.
Suture having a restraining element at an end and method and use thereof
Polymeric fibers, and apparatuses for and methods of processing such fibers to be useful as sutures, where at least one end of a fiber includes a termination feature. The termination feature is formed through the application of energy to a coiled region of the fiber.
Preform charges and fixtures therefor
A preform charge is formed by forming an assemblage of preforms, wherein preforms in the assemblage are bonded to a neighboring preform such that the preform charge effectively becomes a single unit. The preform charge can then be added to a mold to fabricate a part via compression molding.
ELECTRICALLY WELDABLE SUTURE MATERIAL, AND APPARATUS AND METHOD FOR FORMING WELDED SUTURE LOOPS AND OTHER WELDED STRUCTURES
A device for positioning in the body of an animal, the device comprising a first portion and a second portion that may be positioned in contact with one other, the first portion and the second portion each comprising a biocompatible conductive thermoplastic material, such that when the device is positioned in the body of an animal and electric current flows from the first portion to the second portion, heat is generated by electrical resistance at the point of contact between the first portion and the second portion so as to melt regions of the first portion and the second portion, and when the electric current is thereafter terminated, the melted regions of the first portion and the second portion re-solidify so that a weld is formed between the first portion and the second portion.
Elastic entrapment with waist cap bonding
An elastic composite structure includes a first web layer comprising a first portion, a second portion, and a third portion; a second web layer comprising a first portion and a second portion; and a plurality of elastic threads. The first portion of the first web layer is folded over and overlaps the second portion of the first web layer. The folded first portion of the first web layer is directly bonded to one of the second portion of the first web layer and the first portion of the second web layer. A first portion of the plurality of elastic threads is constrained between the folded first portion of the first web layer and the second portion of the first web layer absent adhesive. The third portion is directly bonded to the second portion of the second web layer and traps a second portion of the plurality of elastic threads therebetween.
