Definitions

  • the disclosed technology relates to an article including any of the fiber compositions disclosed herein.
  • the article is a garment or floor covering.
  • the present disclosure relates delustered fiber compositions containing little to no T1O2, articles (finished goods) produced from such delustered fiber compositions, masterbatches for producing such fiber compositions, and manufacturing methods thereof.
  • the disclosed fiber compositions include a matrix polymer, which may be any grade of polyester or nylon suitable for fiber spinning.
  • suitable polyesters include: polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polylactic acid (PLA), poly trimethylene terephthalate (PTT), polyethylene naphthalate (PEN), polyethylene furanoate (PEF), polycyclohexylene dimethylene terephthalate (PCT), sulfonated polyesters, polycaprolactone (PCL), polyhydroxyalkanoate (PHA), copolymers of any of the foregoing, and combinations thereof.
  • the composition includes matrix polymer in an amount of about 97.0 wt% to about 99.99 wt%, about 98.0 wt% to about 99.99 wt%, about 99.0 wt% to about 99.99 wt%, about 97.0 wt% to about 99.7 wt%, about 98.0 wt% to about 99.7 wt%, about 99.0 wt% to about 99.7 wt%, about 97.0 wt% to about 99.5 wt%, about 98.0 wt% to about 99.5 wt%, or about 99.0 wt% to about 99.5 wt%, based on the total weight of the composition.
  • One or more additional components may optionally be included in the disclosed fiber compositions.
  • the amount of light scattering pigment in the masterbatch may be in the range of 0 wt% to about 80 wt%, such as about 5 wt% to about 60 wt%, about 10 wt% to about 40 wt%, or about 30 wt% to about 70 wt%, based on the total weight of the masterbatch.
  • the masterbatch further includes one or more additives and/or colorants as disclosed herein.
  • the term “fiber composition” refers to a delustered, oriented fiber material comprising at least one matrix polymer and at least one incompatible polymer, and little to no titanium dioxide, as discussed above.
  • the fiber composition may be texturized.
  • Non-limiting examples of fiber compositions include partially oriented yam (POY), fully drawn yarn (FDY), other types of yarn, bulk continuous filament (BCF), Drawn Texturized Yam (DTY), and staple fiber.
  • a comparable fiber may be a fiber having the same matrix polymer in an amount that is within 5 wt% of the amount in the disclosed composition, but having more (e.g., 20-50% more) T1O2 than the disclosed composition and no incompatible polymer.
  • This device works by measuring the level of titanium in the fiber, and then assumes the fiber has achieved a certain level of luster based on the content of titanium and assuming that all titanium is in the form of TiCL.
  • a fiber composition containing 0-0.1 wt% T1O2 is presumed to be bright or lustrous
  • a fiber composition containing 0.35-0.50 wt% T1O2 is presumed to be semi-dull
  • a fiber composition containing higher amounts of T1O2 (1.0 wt% or more) is presumed to be dull or fully delustered.
  • the present disclosure also relates to methods of manufacturing the fiber compositions and articles disclosed herein. These methods include mixing the components (i.e., the matrix and incompatible polymers as well as any light scattering pigment(s) and/or additional components that may be present) to achieve uniformity of the blend.
  • the blended batch of ingredients is referred to as a premix, which can be used to make masterbatch pellets.
  • masterbatch pellets contain matrix polymer(s), incompatible polymer(s), optional light scattering pigment(s), optional colorant(s), optional additive(s), and optional dispersant(s).
  • the masterbatch pellets may be manufactured by one of several methods.
  • the method includes premixing, extruding, and pelletizing steps.
  • one method of making masterbatch pellets includes combining the ingredients in a high intensity mixer, such as a Henschel mixer, which includes a mixing bowl with a center shaft that contains one or more mixing blades in a stacked configuration.
  • the premix is then transferred from the mixer to a feeder (e.g., a volumetric feeder), which directs the premix (e.g., via feed auger) into the feed throat of an extruder (e.g., a twin screw co-rotating extruder).
  • a feeder e.g., a volumetric feeder
  • the extruder melt processes the premix using high and low shear dispersing screw elements that disperse any pigments, additives or other components into the polymers.
  • the molten polymer mixture may be conveyed down the length of the extruder, passed through a breaker plate with screens, and through a die head containing holes, thereby forming strands.
  • the strands cool as they pass through a water bath where they solidify.
  • the solid strands may then continue to a pelletizer, which cuts the strands into uniform pellets to form masterbatch pellets.
  • the yarn is further stretched or oriented, causing the scattering sites to elongate and increase the degree of scattering, leading to higher scattering and greater yam delustering.
  • the resulting delustered yarn can then be further processed to form a variety of articles (e.g., clothing, carpeting, furniture, or other technical or industrial textiles) while reducing abrasion on textile spinning and texturizing equipment, therefore extending the life of the equipment and components thereof (e.g., guides, godet rolls, etc.).
  • carpet may be manufactured by subjecting the disclosed fiber compositions to any one or more tufting, dyeing, and/or finishing processes.
  • yam dyeing sometimes called pre-dyeing
  • color is applied to the yarn prior to tufting.
  • Advantages of yarn dyeing methods include good side-by-side color consistency, large lot sizes, and uniformity.
  • carpet dyeing in which color is applied to the yarn after the carpet has been tufted.
  • Suitable carpet dyeing techniques include Beck or batch dyeing, which involves stitching the ends of the carpet together, and then running the tufted carpet loop through large vats of dye and water for several hours. The Beck process is ideal for smaller production runs, and heavier face weight products.
  • Continuous dyeing is similar to Beck dyeing, but involves running the carpet through several processes in addition to the dye application. Continuous dyeing applies color directly to the carpet face, such as by spraying or printing.
  • the disclosed fiber compositions can also be used to manufacture various types of garments, including athletic wear such as exercise shorts, leggings, and shirts for all sporting activities.
  • these articles are made primarily from polyester with blends of other polymers like spandex, cotton, and nylon woven or knitted into the garment to provide flexibility and comfort.
  • Suitable processes for making garments generally include fiber spinning and fabric weaving or knitting.
  • Visual Luster Visual assessments of luster were performed and recorded on a scale of 1- 5. According to this visual assessment, an oriented fiber exhibiting a high visual luster was assigned a value of 5 (bright), and an oriented fiber exhibiting a low visual luster was assigned a value of 1 (dull). Gradations of intermediate luster were assigned a value of 2, 3, or 4, with the lower values indicating correspondingly lower degrees of luster.
  • the matrix polymer (major phase) was dried polyethylene terephthalate (PET) having an intrinsic viscosity (IV) about 0.80 dl/g and a glass transition temperature (Tg) of 70°C - 80°C;
  • the incompatible polymer (minor phase) was polymethylpentene (PMP) (TPX RT-31 manufactured by Mitsui Chemical); and the light scattering pigment was anatase titanium dioxide (TiCh).
  • PMP polymethylpentene
  • TiCh anatase titanium dioxide
