Definitions

  • the present invention relates to a method for knitting a windproof fabric, according to the preamble of claim 1 and as known from US 2007/125130 .
  • Woven fabric has the characteristics of high density, inelastic, starchy, and water resistant, while knitted fabric is low density, elastic, and soft and breathable. Different fabric manufacturing methods are used for different products. If clothes are made of woven fabric in order to be water resistant, the characteristics of high density and inelasticity of the woven fabric make the cloth relatively stiff and uncomfortable to wear.
  • the knitted fabric 10, as shown in Figs. 1 and 2 has a relatively low density due to the loops 11 are relatively long, which makes the knitted fabric 10 soft and comfortable to wear. However, the low density knitted fabric 10 is not resistant to water. Also because the loops 11 are relatively long, the knitted fabric is relatively loose and more likely to be damaged.
  • US 2007/125130 A1 discloses a method for producing a windproof and air-permeable knit fabric through several steps of feeding a yarn at a predetermined feeding speed, and subjecting a surface of the knitted windproof fabric to a quality medication process.
  • WO 98/26118 A1 discloses a cloth consisting at least partially of fibers or yarns which are composed of at least two or more components with different melting points but manufactured from the same raw material.
  • EP 1 803 844 A1 discloses an air permeable woven or knitted fabric and clothes containing crimped composite filaments formed from a polyester resin component and a polyamide resin component different from each other in thermal shrinkage and bonded together in a side by side manner.
  • EP 1 403 410 A1 discloses insulated knitted fabric comprising a single layer or two or more layers, and at least an outer layer is composed of fibers having a single filament.
  • EP 0 908 544 A1 discloses a crimp-forming conjugate multifilament yarn comprising at least two polyester components with different heat-shrinkage properties, the components are combined in parallel with each other to form knitted products with unique surface texture and stretch ability.
  • the present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
  • a method for knitting a windproof fabric is provided, wherein the fabric is knitted by a yarn which is made of two types of fibers which have different BWS (boiling water shrinkage) values, so that the knitted fabric is not only comfortable to wear, but also water resistant.
  • BWS blowing water shrinkage
  • a method for knitting a windproof fabric wherein the yarn is knitted at a predetermined knitting speed which is faster than the feeding speed, so as to increase the density of the knitted windproof fabric, and consequently achieving the function of windproof and water resistance.
  • a method for knitting a windproof fabric comprises the following steps:
  • the knitted windproof fabric comprises a plurality of loops which are tightly interlaced with one another, and has a wale (or warp) density of 50 ⁇ 150g/in, a course (or weft) density of 80 - 140g/in and a weight of 60 - 210g/SQM.
  • a method for knitting a windproof fabric in accordance with the present invention comprises the following steps:
  • the yarn is made of two types of fibers which have different BWS values (boiling water shrinkage), a first fiber is 15 D - 100D (Denier) polyester fiber with a boiling water shrinkage of BWS value of 15 - 85 %, and a second fiber is 15D ⁇ 100D polyester fiber with a BWS value of 0 ⁇ +15%, or a 20D ⁇ 160D Nylon fiber with a BWS value of 0 ⁇ +15%.
  • BWS values blowing water shrinkage
  • the first and second fibers are mixed at a predetermined weight (or volume) ratio, for example, at the ratio of 1:1.5 ⁇ 1:10.5.
  • the first and second fibers are a long fiber and a short fiber, respectively, and mixed in such a manner that the long fiber is a core, and the short fiber wraps the long fiber up, or, the short fiber is a core and wrapped up by the long fiber, so as to make the physical property of the yarn fall in between the physical properties of the two types of fibers which form the yarn (the yarn formed by the two different fibers is endowed with the physical properties of both fibers. Adjusting the ratio between the two fibers can make the property of the yarn close to the physical property of the long fiber or the short fiber.
  • the windproof fine gauge knitted fabric is a single layer or double layer flannel or brushed fabric and treated with quality modification process to meet the quality requirements of ISO 9237, and the wind pressure resistance performance and the breathability of the fine gauge knitted fabric are 100PA, and 50 ⁇ 100 cm 3 /cm 2 /s, respectively.
  • the windproof fine gauge knitted fabric 40 as shown in Figs. 4 and 5 , comprises a plurality of loops 41 which are tightly interlaced with one another, so that the intervals among the loops 41 are reduced to a certain extent to make the knitted windproof fabric 40 water resistant and windproof.
  • the present invention since the yarn is fed at relatively low feeding speed, the length of every loop 41 of the knitted windproof fabric 40 will be reduced, and so will be the density of the loops 41 of the knitted windproof fabric 40. Since the knitted windproof fabric 40 is a knitted structure, it is soft, elastic and comfortable to wear. Furthermore, the present invention changes the proportion of the yarning feeding speed and the knitting speed, so as to increase the density of the loops 41 of the knitted windproof fabric 40, and consequently makes the knitted windproof fabric 40 windproof and even water resistant.
  • the abovementioned knitted windproof fabric 40 is a single jersey fabric, and it can also be a double jersey fabric, as shown in Fig. 6 .
  • the knitted windproof fabric 40 formed after the step of knitting 30 can be subjected to a quality modification process, which is a heating process used to heat the knitted windproof fabric 40, so that the surface of the knitted windproof fabric 40 will be firstly melted and then cured after the heating process, and will accordingly become less elastic and more stable, while the density of the knitted windproof fabric 40 doesn't change.
  • a quality modification process which is a heating process used to heat the knitted windproof fabric 40, so that the surface of the knitted windproof fabric 40 will be firstly melted and then cured after the heating process, and will accordingly become less elastic and more stable, while the density of the knitted windproof fabric 40 doesn't change.
  • one surface of the knitted windproof fabric 40 can be subjected to the quality modification process to provide a better windproof and water resistance performance, and this surface of the knitted windproof fabric 40 subjected to the quality modification process can be used as an external surface, while the other surface of the knitted windproof fabric 40 which is not subjected to the quality modification process can be used as an inner surface which is to be in contact with the wear's skin to provide better wearing comfort.
  • the quality modification process is to heat the knitted windproof fabric 40 at 190 - 205°C for 1 ⁇ 5 seconds, so as to make the knitted windproof fabric 40 meet the quality requirements of ISO 9237, and the wind pressure resistance performance and the breathability of the fine gauge knitted fabric are 100PA and 3-50 cm 3 /cm 2 /s, respectively. Furthermore, the knitted windproof fabric 40 is water passes the AATCC35 rain test.
  • the present invention is aimed at providing a method for knitting a windproof fabric, and the test data of the fabrics knitted by the method of the present invention are as shown in table 1, wherein the breathability of the respective fabrics ranges 3-50 cm 3 /cm 2 /s, which means that all the fabrics are windproof.
  • the fabrics with the reference numbers: R6033, R6267, R0091, R1268 and R2156 all have a water permeability less than 1g, which means that these fabric are water resistant.
