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： A polyamide 56 resin, a fiber, a preparation method therefor and use thereof are provided. The method for preparing the polyamide 56 resin comprises a step of preparing the polyamide 56 resin from monomers by a polymerization reaction, wherein the polyamide 56 resin contains titanium dioxide, and the titanium dioxide is added during polymerization. The method for preparing the polyamide 56 resin in an embodiment can effectively prevent problems such as monofilament breakage and poor dyeing performance in a subsequent spinning process. In addition, the method is simple and easy to operate, and has a low production cost.

摘要： A process for improving the uniformity of yarn finish application on the individual filaments of a rapidly advancing synthetic continuous monofilament, bonded multi-filament, multi-filament hosiery, textile, technical and industrial yarns includes imparting a pneumatic false twist to the advancing yarn having a wet finish thereon while the yarn is under a tension allowing the rapid opening and closing of the multi-filament yarn but preventing texturing or coherency from increasing by commingling of the yarn filaments in the false twister. A nozzle has a reduced friction and can either be used as a stand-alone air bearing or to apply finish within the nozzle. A plurality of finish delivery orifices open into the chamber in a low pressure zone inside the nozzle, and wherein the exact same or slightly greater pressure that is used for the compressed air supplied to the air delivery orifices is used to actuate the finish supplied to the plurality of the finish delivery orifices. The process and apparatus can also be used with monofilament textile yarn and bonded textile yarn.

摘要： It has been suggested that synthetic multifilamentary yarns can be produced by melt-spinning a polyamide or polyester polymer under conditions of substantially simultaneous spinning and drawing wherein prior to said drawing the filaments of the fiber are lubricated with a spin finish by surface contact with a lube roll surface of not less than about 90 RMS. However, in commercial operation of the process at high throughput rates of 50 pounds per hour or greater through the spinneret, serious problems have been encountered due to "flicking" or momentary slackness of one or more filaments from the main yarn bundle above the lube roll, which flicking results in production of yarn of relatively poor quality. It has now been found that the occurrence of said flicking of the filaments can be greatly reduced by applying the spin finish from a convergence guide having a yarn-lubricating surface of not less than about 10 RMS and means for distributing a film of lubricant over said surface. The resulting high-strength multifilament yarn having relatively uniform quality is particularly applicable for tire and industrial uses.
摘要翻译：已经提出合成复丝纱可以通过在大体上同时进行纺丝和拉伸的条件下熔融纺丝聚酰胺或聚酯聚合物来生产，其中在所述拉伸之前，纤维的长丝通过与润滑剂的表面接触用旋涂完成润滑辊面不小于约90 RMS。然而，在通过喷丝头以50磅/小时或更高的高生产率进行的该方法的商业操作中，由于来自润滑油辊上方的主纱线的一根或多根细丝的“轻弹”或瞬时松弛，已经遇到严重问题，其轻拂导致质量相对较差的纱线的生产。现在已经发现，通过从具有不小于约10个RMS的纱线润滑表面的会聚引导器施加旋转抛光，可以大大减少所述丝状物的发生，以及用于在所述表面。所得到的具有相对均匀质量的高强度复丝纱特别适用于轮胎和工业用途。

摘要： A method for tuning characteristics of a polyamide nanofiber nonwoven comprising the step of targeting a specific average nanofiber diameter and/or a specific relative viscosity for the polyamide nanofiber nonwoven. The specific average nanofiber diameter is within a range from 100 nm to 1000 nm and/or the specific relative viscosity is within a range from 5 to 75, e.g., from 15 to 50. The process further comprises the steps of extruding a polyamide composition having a moisture content with a pressurized gas through a fiber forming channel having a channel temperature to form the polyamide nanofiber nonwoven having the target average nanofiber diameter and/or relative viscosity and controlling the moisture content, the pressure of pressurized gas, and/or the channel temperature based on the specific average nanofiber diameter and/or the specific relative viscosity.

摘要： Biocompatible coatings and spin finishes that can be applied to polyhydroxyalkanoate (PHA) polymers, and medical devices made from PHA polymers, have been developed. The coatings impart good lubricity to PHA polymers, particularly to fibers and braids made from these materials, making the coatings ideal for use on medical devices such as PHA braided sutures. The spin finishes can be applied to PHA fibers to facilitate their manufacture, and also for their conversion to other products, including medical textiles. The spin finishes serve to protect multifilament fiber bundles, and keep them intact following extrusion, and also to impart lubricity to the fiber bundles and monofilament fibers so that they are not damaged in subsequent processing steps particularly in textile processing. The coating reduces tissue drag of, for example, braided sutures.
