Definitions

  • the present invention pertains to a textile fabric and workwear manufactured thereof.
  • Textile fabrics are known. This type of fabrics should especially be heat protective and should also exhibit sufficient mechanical properties, for example sufficient tear strength.
  • US 2011/0138523 A1 describes a heat, flame and electric arc protective for use as single layer of a protective garment for a wearer, the fabric comprising: interwoven warp and weft yarn wherein the warp and weft yarn comprises a blend of 8 to 33 wt.-% meta-aramid staple fibers, 65 to 90 wt.-% para-aramid staple fibers, and 2 wt.-% anti-static staple fibers, the weft yarn and warp yarn being identical and comprising the side of the fabric facing away from a wearer and the side of the fabric facing the wearer, wherein the fabric provides ablative thermal protection on both sides.
  • a fabric with a twill K 2/ 1Z construction and with a grammage of 230 g/m 2 exhibits a tear resistance of the warp to be 67.87 N and of the weft to be 34.4 N, measured using the ISO 13937-1:2000 test procedure.
  • EP 1740746 B1 describes a heat and flame resistant fabric for use as single or outer layer of protective garments.
  • This fabric comprises fibers with a blend of 60 to 90 wt.-% of meta-aramid staple fibers and 5 to 40 wt.-% of para-aramid fibers.
  • This fabric does not comprise polylactide staple fibers.
  • WO 02/40755 A2 describes a fire resistant corespun yarn comprising a core of high temperature resistant continuous inorganic filaments and a first and a second sheath of staple fibers.
  • the first sheath comprises natural and synthetic staple fibers with at least one fire retardant fiber.
  • the staple fibers of the second sheath are selected from natural staple fibers or synthetic staple fibers.
  • WO 02/40755 A2 is silent about a blend of meta-aramid staple fibers and para-aramid staple fibers with poly lactic acid staple fibers.
  • a staple fiber composition DuPont TM Nomex ® IIIA is known consisting of 93 % Nomex ® m-aramid staple fibers, 5 % Kevlar ® p-aramid staple fibers, and 2 % antistatic staple fibers. According to an internet presentation of DuPont a fabric made of the staple fiber composition DuPont TM Nomex ® IIIA meets the NFPA 1975 standard for firefighters' station wear and is resistant to abrasion and tears.
  • the problem underlying the present invention is to provide a fabric which exhibits higher tear strength and higher wear comfort in garments, especially workwear made thereof.
  • a textile fabric comprising a staple fiber yarn made of a staple fiber blend, wherein the blend comprises meta-aramid staple fibers, para-aramid staple fibers, and poly lactic acid staple fibers.
  • the textile fabric according to the invention exhibits a higher resistance against abrasion and tear than a comparative textile fabric made from a staple fiber yarn which was manufactured from a staple fiber mixture consisting of meta-aramid staple fibers, para-aramid staple fibers and antistatic staple fibers. So, a garment comprising the textile fabric according to the invention can be worn for a longer time before it becomes damaged.
  • the higher values for resistance to abrasion and tear of the textile fabric according to the invention can be obtained with a lower grammage of the textile fabric, if compared with the grammage of a comparative textile fabric made of a staple fiber yarn which was manufactured from a staple fiber mixture consisting of meta-aramid staple fibers, para-aramid staple fibers and antistatic staple fibers. So, a garment comprising the textile fabric according to the invention can be worn with a higher wear comfort than a garment comprising the comparative textile fabric.
  • a garment comprising the textile fabric according to the invention wherein the grammage of the textile fabric is increased to the value of the grammage of the comparative textile fabric, can be worn with the same wear comfort as the garment comprising the comparative textile fabric but for an even longer time, because the resistance of the garment with the textile fabric of the invention to abrasion and tear is even more increased.
  • the textile fabric according to the present invention surprisingly fulfills the minimum requirements in terms of radiant heat, convective heat, and contact heat.
  • the poly lactic acid component of the textile fabric can be fully recycled, because poly lactic acid is fully biodegradable resulting in compost.
  • the compost can be used as substrate to grow corn.
  • the corn can be fermented to lactic acid which can be polymerized to poly lactic acid from which poly lactic acid staple fibers can be manufactured. Therefore, the textile fabric according to the invention contains a renewable component.
  • staple fibers means fibers of limited length obtained from cutting or breaking a filament yarn.
  • metal-aramid staple fibers means staple fibers obtained from cutting or breaking a meta-aramid filament yarn
  • metal-aramid means a polymer obtained by the polycondensation of a meta-oriented aromatic diamine and a meta-oriented dicarboxylic acid halide, wherein said polymer exhibits recurring units having amide bonds, and preferably at least 85 % of said amide bonds are located in the meta-oriented positions of the aromatic ring.
