The present invention relates to a method for producing a functional yarn, in which zirconium phosphate having a multiple-layered structure is used as a deodorizing material and a melted polymer is spun through a spinning nozzle having a multi-lobal sectional shape. According to the present invention, the melted polymer contains layered fine zirconium phosphate inorganic particles having low hardness, and thus the abrasion of production process equipment can be minimized during fiber production and also an excellent deodorizing property and an excellent sweat-absorbing and quick-drying property are exhibited.

A method of making nonwoven webs comprising providing a spinneret wherein the spinneret includes a pattern of conduits, the pattern of conduits forming an extrusion region; directing only a first stream of molten propylene polymer having a first temperature into a region adjacent of the first side of the spinneret, directing only a second stream of molten propylene polymer having a second temperature into a region distal to the first side of the spinneret, extruding only the first stream of molten propylene polymer through the exit openings in a first zone; extruding only the second stream of molten propylene polymer through the exit openings of a second zone; the second zone is distal to the first side with the first zone being between the second zone and the first side.

A nonwoven recyclable fabric and associated methods are provided. The fabric is formed from 100% polyester, and may also include surface coatings such as hydrophilic coatings to promote heat transfer as well moisture vapor transmission rates and/or a silicone coating to promote fabric smoothness and reduce abrasiveness of the fabric.

High strength or load bearing nylon fiber with break tenacity greater than 7.5 g/den and/or a tenacity at 10% elongation of greater than 4.0 g/den as well as yarns, fabrics and articles of manufacture thereof and methods for their production are provided.

Systems for producing M yarns, wherein M≥1, include N extruders, M spin stations, and a processor, wherein N>1. Each extruder includes a thermoplastic polymer having a color, hue, and/or dyability characteristic, which are different from each other. Each spin station produces one yarn comprising at least one bundle of filaments. Each spin station comprises at least one spinneret through which filaments are spun from at least two molten thermoplastic polymer streams received by the respective spin station and N spin pumps upstream of the spinneret for the respective spin station. Each spin pump is paired with one of the N extruders. The processor is in electrical communication with the N*M spin pumps and is configured to adjust the volumetric flow rate of the polymers pumped from each spin pump to achieve a ratio of the polymers to be included in each M yarn.
