Definitions

  • the present invention relates to an air permeable and waterproof stretchable woven fabric. More particularly, the present invention relates to an air permeable and waterproof stretchable woven fabric without coating with or laminating rubbers or films, the woven fabric can still obtain elasticity and better stretchability in the directions of the longitude and the latitude and can be waterproof and highly air permeable.
  • the water pressure resistance of the high density fabric without coating or laminating improves a lot now to a value of 600 ⁇ 1300mm/H 2 O. Since it is not stretchable, clothes made of it provide no stretchability and less comfort on wearing it.
  • the main purpose of the present invention is that, without coating with or laminating rubbers or films, the woven fabric can obtain elasticity and better stretchability in the directions of the longitude and the latitude and can be also waterproof and highly air permeable.
  • the present invention is an air permeable and waterproof stretchable woven fabric comprising the following processes: warping and weaving the warps and the wefts to obtain a gray fabric; adding stretchable yarns into the warps and the wefts of the gray fabric to obtain elasticity in the directions of the longitude and the latitude and to obtain better stretchability; and, dyeing and finishing the gray fabric to obtain a gray fabric with waterproofing and high air-permeability.
  • the fabric can obtain elasticity and better stretchability in the directions of the longitude and the latitude and can be waterproof and highly air permeable.
  • FIG.1 through FIG.5 show a cross-sectional view of the structure on the longitude direction, a cross-sectional view of the structure on the latitude direction, a view of the dyeing heat-up curve, a flow chart of the preparatory fixing and a flow chart of the post fixing, according to the present invention.
  • the present invention is an air permeable and waterproof stretchable woven fabric whose warps 1 and wefts 2 are warped and woven to obtain a gray fabric.
  • the warping process comprises steps of winding, warping, lapping, warp beaming, starching, lapping, doubling, and cloth warp beaming.
  • the weaving process comprises steps of cloth warp beaming, harnessing, weaving, installing drop wire, setting up the weaving parameters, and obtaining high-density fabric (gray fabric).
  • the gray fabric with high coverage is obtained through controlling the density by the weaving process.
  • Stretchable yarns are added into the warps 1 and the wefts 2 of the gray fabric to obtain elasticity in the directions of the longitude and the latitude and to obtain better stretchability, wherein FIG.1 shows the cross-sectional view on the longitude direction and FIG.2 shows the cross-sectional view on the latitude direction.
  • the dyeing-and-finishing process comprises steps of desizing, refining, preparatory fixing, dyeing, drying, and post fixing and finishing.
  • the temperature for the desizing is between 80°C (Celsius degree) and 100°C where its speed is between 30m/min and 50m/min (°C: degrees Celsius; m: meter; min: minute).
  • the temperature for the preparatory fixing is between 170°C and 200°C where its speed is between 30m/min and 55m/min.
  • the dyeing can be done by using liquid-overfeed dyeing machine or air-flow dyeing machine.
  • the temperature for the post fixing is between 160°C and 190°C where its speed is between 30m/min and 50m/min.
  • the fabric is wetted through a water tank 3 and is passed through a plurality of ovens 4 and then is plaited (As shown in FIG.4).
  • the fabric is passed through a pressure absorber 5 which comprises water repellent to make the fabric capable of water repellence; then the fabric is passed through a plurality of ovens 6; and then the fabric is plaited (As shown in FIG.5). So forth, the gray fabric becomes a fabric with waterproofing and high air-permeability.
  • the fabric is a synthetic fiber comprised of textured yarns, wherein its C.F.
  • cover factor value is between 2500 and 4200 and its C.F.S. (cover factor stretch) value is between 15000 and 35000.
  • stretch-and-recovery ratio is between 75% and 95% (ASTM D4964 under a stretch ratio of 30%); the ratio for its stretchability is between 10% and 35% (ASTM D3107); and its water vapor permeability is between 6000g/m 2 /24hrs and 9000g/m 2 /24hrs (JIS L1099 A1) or between 15000g/m 2 /24hrs and 35000g/m 2 /24hrs (JIS L1099 B1) (g: gram; hrs: hours).
  • the fabric is water repellent with a value above 90 (AATCC 22) even after thirty times of washing (AATCC 135). It can pass the RAIN-TEST (AATCC 35). Its water pressure resistance remains the same even after washing (AATCC 135). Its air-permeability is between 1.5cm 3 /cm 2 /s and 11 cm 3 /cm 2 /s (cm: centimeter; s: second). Accordingly, a novel air permeable and waterproof stretchable woven fabric is obtained.
  • Fig. 6 shows in a table 1 the result data of the experiments according to (1) the present invention, (2) a regular density with stretchability, and (3) a high density without stretchability.
  • the fabric made according to the present invention is better than the stretchable fabric with regular density and the non-stretchable fabric with high density on C.F. value, stretchability, C.F.S. value, water vapor permeability, water pressure resistance, water repellence, and air permeability.
  • the present invention can obtain elasticity and better stretchability in the directions of the longitude or the latitude or both and can be waterproof and highly air permeable without coating or laminating rubbers or films.
