Definitions

  • the present disclosure relates to polyester fiber.
  • Denier Denier is a unit for the measurement of linear mass density of fibers. It is defined as the mass in grams per 9000 meters.
  • Tenacity is the customary measure of strength of a fiber or yarn. It is expressed as grams per denier (gpd).
  • Fiber Elongation Fiber elongation is specified as the percentage of increase in length as compared to the initial length.
  • Uster value Uster value is the measurement of evenness, thick places, and thin places in fiber.
  • Quenching It is a method used for rapid cooling of melt to obtain fibers.
  • Draw Ratio Expressed as the ratio of cross sectional area of undrawn material to that of the drawn material.
  • Wicking Wicking is the absorption of a liquid by a material in the manner of a candle.
  • Fibers One of the major use of Fibers is for manufacturing apparel, carpet, upholstery, etc.
  • Viscose fibers are widely used in the manufacturing process of various fabrics. Fabrics made from the viscose fibers are pleasing to touch and breathes like cotton, however, fabrics made from viscose fibers wrinkle easily and many garments made from this fabric cannot be machine-washed or dried. Also, the manufacturing process of such fibers creates a lot of pollution. Further, the cost of the viscose fiber is also high.
  • One of the prerequisite for the selection of fiber before manufacturing the fabric is the moisture retention property of the fabric. The moisture management of the fabric depends a lot on the type of fiber used. The ability of a fabric to transport moisture away from the skin to the garment's outer surface is one of the key performance criteria for manufacturing sports and active outdoor clothing.
  • Natural fibers tend to absorb and retain body moisture which makes the body to feel uncomfortable, whereas synthetic fibers tend to move away the moisture from the body leading to efficient evaporation of the moisture.
  • conventional synthetic fibers suffer from the problem of poor moisture management because of their poor wicking characteristics. Further, the conventional fibers suffer from the problem of low availability of surface area which is also responsible for its poor moisture management property.
  • An object of the present disclosure is to provide a polyester fiber characterized by non- circular cross section.
  • Another object of the present disclosure is to provide a gear shaped cross section fiber having improved moisture management properties.
  • Yet another object of the present disclosure is to provide a yarn made from the gear shaped cross section fiber. Still another object of the present disclosure is to provide a woven fabric having improved moisture management property.
  • polyester fiber characterized by:
  • ⁇ tenacity in the range of 2.0 to 10.0 grams per denier (gpd);
  • the polyester fiber of the present disclosure is made from at least one polyester resin selected from the group consisting of polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and polytrimethylene terephthalate (PTT).

  • the polyester fiber of the present disclosure is used for the manufacturing of yarn.
  • a woven fabric is made from this yarn.
  • the woven fabric, made from the yarn of the polyester fiber of the present disclosure has a high wicking property characterized by a wicking height in the range of 100 mm to 130 mm.
  • the woven fabric has a denier per filament in the range of 1 to 6 of the yarn made from the polyester fiber of the present disclosure.
  • the woven fabric comprises the yarn made from the polyester fiber of the present disclosure, in a weight fraction in the range of 50 to 100% of the woven fabric.
  • Figure 1 illustrates cross sectional view of the polyester fibers having gear shaped cross section
  • Figure 2 illustrates the longitudinal view of the polyester fibers having gear shaped cross section.
  • Viscose fibers are widely used in the manufacturing of fabrics. But, the production process of the viscose fiber causes a lot of pollution to the environment.
  • polyester fiber In accordance with one embodiment of the present disclosure, there is provided polyester fiber.
  • the polyester fiber of the present disclosure is characterized by: ⁇ gear shaped cross section; • linear mass density in the range of 0.6 to 10 denier per filament;
  • the polyester fiber of the present disclosure is made from at least one polyester resin selected from the group consisting of polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and polytrimethylene terephthalate (PTT).
  • PET polyethylene terephthalate
  • PBT polybutylene terephthalate
  • PTT polytrimethylene terephthalate
  • the process for the manufacturing of the polyester fibers of the present disclosure comprises the following steps: Initially, a polymeric material is fed to an extruded wherein the polymeric material is melted at a temperature in the range of 260 to 300 °C and a molten mass is obtained. The molten mass thus obtained is passed through a spinneret, wherein the spinneret plate comprises a plurality gear shaped holes. The molten mass, after passing through the spinneret plate, results into a plurality of filaments having gear shaped cross section. These filaments, having gear shaped cross section, are quenched at a temperature in the range of 20 to 25 °C using air.
  • the air flow rate used for quenching is in the range of 0.4 to 0.7 m/s. Due to quenching, the filaments coming out of the spinneret holes freeze instantly and the filaments thus obtained showed a uniform and similar cross section as that of the spinneret holes. Further, the filaments are cut in desired length to obtain fibers having gear shaped cross section as shown in Figure 1 of the present disclosure, which can be used in various applications.
  • the polyester fiber of the present disclosure is used to make yarn. Further, a woven fabric is made from this yarn. The woven fabric thus obtained has improved moisture management property.
  • the woven fabric is characterized by: ⁇ wicking height in the range of 100 mm to 130 mm; and
  • the woven fabric comprises the yarn made from the polyester fibers of the present disclosure, in a weight fraction in the range of 50 tol00% of the woven fabric. Further, the cross section geometry of the polyester fibers of the present disclosure imparts bounciness and high yarn to yarn friction to the fabric made therefrom. The fabric thus obtained, can withstand alkali weight reduction upto 40%.
  • PET Polyethylene terephthalate
  • Experiment 2 A woven fabric was made from the yarn of Experiment 1. The moisture management property of the woven fabric made from the yarn of Experiment 1, was tested with the woven fabric made from the yarn of conventional PET fibers having circular cross section and the woven fabric made from yarn of conventional PET fibers having non-circular cross section fiber. A wicking test was conducted to compare their moisture management properties in terms of wicking height. All the fabrics were soaked in water for 20 minutes and then compared to check their corresponding wicking heights. The results thus obtained are tabulated in Table 1 herein below. Table 1: Wicking height after 20 minutes:
  • the woven fabric made from the yarn of PET fibers having gear shaped cross section showed the highest wicking height compared to the fabrics made from the yarn of conventional fibers. Therefore, confirms improved moisture management property of the fabric made from the yarn of PET fibers having gear shaped cross section.
