Definitions

  • the present invention relates to a multilayer lining fabric having improved properties in respect of elasticity and stretchability. Moreover, the present invention relates to a multilayer lining fabric which improves safety features of the fabric. In a further embodiment, the invention relates to clothes, in particular working clothes, comprising a multilayer lining fabric.
  • Lining fabrics in particular for clothes used in a specific area as, for example, clothes worn in sports or clothes worn in a working environment, are requested to meet certain requirements concerning the wearer's comfort: Due to the fact that such clothes often need to protect the wearer against uncomfortable weather conditions (low temperature, external wetness resulting from snow or rain), they have to comprise an outer layer protecting against such conditions.
  • the physical conditions of sports or working in the open air are characterized by a large extent of body movements (or movements of certain parts of the body only, e. g. the arms, the upper part of the body, the legs and/or the lower part of the body) and, in connection to that, sweating of the body.
  • lining fabric is the warp-knitted fabric available on the market from the company Engtex AB, Mullsj6, Sweden, under the Trade Name "ENGTEX".
  • the lining does allow such easy body movements to a restricted extent, only (or even prevents such movements), due to a lack of elasticity and stretchability of the lining fabric. This is particularly true for linings made of the above warp-knitted fabrics, which were placed inside the protecting layer in two or more layers one above the other, conventionally, with the warp directions of one layer parallel to those of each other lining layer.
  • the humidity transport (resulting from sweating by the wearer) from the wearer's skin to the environment through the multilayer lining fabric be improved, thereby preventing skin irritations or even inflammations from occurring.
  • clothes comprising the multilayer lining fabric of the invention be provided, thereby allowing better wearing comfort to the wearer, for example in the case of sports clothes or working clothes and, in particular, working clothes for chainsaw operators and forest workers.
  • a multilayer lining fabric wherein two or more layers of a warp-knitted fabric are combined to a lining fabric by a stack of said two or more warp-knitted fabric layers, the warp directions of which are twisted, from one layer to the next, by an certain angle. If a stack of such twisted lining fabrics is stitched loosely-fitting, the resulting multilayer lining fabric in a piece of clothing has a largely enhanced elasticity and may stretch during the movements of the clothes' wearer, thereby providing an improved comfort.
  • the present invention relates to a multilayer lining fabric comprising at least two warp-knitted fabric layers of at least one polymer thread material having a weight of ⁇ 100 g/m 2 (per layer of material) wherein the number of weft threads is larger than the number of warp threads, wherein, in the plane of the layers of the fabric, the direction of warp threads of one layer is twisted with respect to the direction of warp threads of an adjacent layer by an angle ⁇ of at least 20 °.
  • the present invention also relates to clothes comprising the multilayer lining fabric according to the present invention.
  • the present invention relates to a multilayer lining fabric.
  • lining fabric is defined to mean a textile material made in the form of a plurality of layers each of which consists of textile material threads.
  • Such thread layers in the case of the present invention, are manufactured by a process of warp-knitting.
  • the process of warp-knitting is a knitting method in which the thread zigzags along the length of the fabric and, hence, follows adjacent columns of knitting, i. e. a knitting direction which follows the length direction of the knitted textile material. In an exemplary manner, this is shown in Figure 1 , wherein the arrow shows the direction of the warp thread.
  • Such a textile material or fabric is used as a lining under a surface layer or as a protective fabric layer (e. g. of a piece of clothing) in order to generate an underlayer having specific properties.
  • the lining fabric is a multilayer lining fabric, i. e. has a number of layers of at least two:
  • at least two warp-knitted fabric layers of a polymeric thread material are comprised.
  • the number of layers is not restricted to "two" and may comprise, in preferred embodiments of the invention, 2, 3, 4, 5, 6, 7, 8 or 9 or even more warp-knitted fabric layers.
  • An exception is the fact that a larger number of layers increases the overall weight of the multilayer lining fabric of the invention, the latter being in contrast to the object of providing a multilayer lining fabric enhancing the wearing comfort for the wearer of the fabric or of the clothes comprising said fabric, because the fabric's weight increase makes movements in the wearer's sports or working environment more cumbersome.
  • a number of layers of ⁇ 5 is preferred, and even more preferred is a number of 6, 7, 8 or 9 warp-knitted fabric layers.
  • the polymeric thread material may be one polymeric thread material which is identical in all layers of the multilayer lining fabric or may be two or more polymeric thread materials in different layers of the multilayer lining fabric.
  • a skilled person may select such one (or two or even more) polymeric thread materials from a large number of materials, which are known in the art per se , in accordance with the specific requirements of each single case.
  • one single polymeric thread material for all layers of the multilayer lining fabric of the invention is preferred; this does, however, not restrict the invention to this preferred embodiment.
  • the material of the (at least two) warp-knitted fabric layers is a polymer thread material.
  • Polymers for threads which may be employed for knitting the warp-knitted fabric layers of the present invention are well-known to a skilled person and may be selected from a large number of polymer materials in accordance with the requirements of a specific case, subject to the parameters of the material.
  • One of those parameters is, naturally, that the polymer must be capable of being made into threads which are suitable for the machine knitting process.
  • Another criterion is the requirement that the material, in the form of a thread, must be capable of being knitted into a fabric material by a warp-knitting process.
  • the polymer material after being warp-knitted into a fabric layer has a weight of > 100 g/m 2 .
  • Polymer material fabrics having a weight of > 100 g/m 2 may be warp-knitted into light-weight lining fabrics having good mechanical properties, as for example excellent stretchability, light weight and good humidity-dissipating properties.
  • the materials used in each fabric layer have a weight in the range of from 120 to 180 g/m 2 , preferably in a range of from 140 to 160 g/m 2 , more preferably in a range of 160 ⁇ 5 g/m 2 .
  • Exemplary (but not restricting) weights of the polymer material after being warp-knitted into a fabric layer are 132 g/m 2 or 162 g/m 2 or 114 g/m 2 or 148 g/m 2 or 171 g/m 2 , and such specific weights may be used in combination with others, while having advantageous properties for the invention. Materials having the afore-mentioned weight were found to be particularly suitable for the multilayer lining fabric of the present invention.
  • the materials have a thickness in the range of from 0.4 to 1.0 mm, preferably within a range of from 0.6 to 0.8 mm, more preferably within a range of from 0.65 to 0.75 mm, most preferably about 0.7 mm. Materials having the afore-mentioned thickness were found to be particularly suitable for the multilayer lining fabric of the present invention.
  • the polymer thread material is a polyester or polyamide.
  • Polyesters are particularly preferred materials, since they result into multilayer lining fabrics convenient for the wearer and presenting, in addition, good safety properties, as will be shown below in detail.
  • a skilled person is familiar with polyesters and polyamides, particularly with polyesters, as polymer thread materials known in the present field of the art and may select such polyesters from a large group thereof in accordance with the requirements of a specific case.
  • the polymer thread material may be poly (ethylene terephthalate) (PET).
  • PET poly (ethylene terephthalate)
  • One specific material available on the market has turned out to be a particularly suitable material, which material is available from the Company Engtex AB, Mullsjö, Sweden, under the Trade Name "ENGTEX Dyneema”.
  • the warp-knitting of the fabric layers was made resulting into a number of weft threads per centimeter of length of the fabric layers which is larger than the number of warp threads per centimeter of width of the fabric layers, which number ratio represents the density of knitting of the fabric layer material.
  • each layer the number of warp threads is 4.5 ⁇ 0.5 threads/cm and/or wherein the number of weft threads is 6.5 ⁇ 0.5 threads/cm.
  • Fabric layers of a polymer thread material having been warp-knitted on warp-knitting machines into fabrics having thread densities in the above ranges show particularly good improvements of their properties.
  • the multilayer lining fabric comprises at least two warp-knitted fabric layers of at least one polymer thread material, which layers are superimposed one on another, and the number of warp-knitted fabric layers may be 2, 3, 4, 5, 6, 7, 8 or 9 or even more warp-knitted fabric layers, as mentioned above.
  • 2, 3, 4, 5, 6, 7, 8 or 9 or even more warp-knitted fabric layers are superimposed on one another, and even more preferable is a number of 6, 7, 8 or 9 warp-knitted fabric layers, for example 7, 8 or 9 warp-knitted fabric layers, and most preferable 9 warp-knitted fabric layers which are superimposed on one another.
  • the direction of warp threads of one layer, in the plane of the layers of the fabric is twisted, with respect to the direction of warp threads of an adjacent layer, by an angle ⁇ of at least 20 °.
  • of at least 20 °.
  • FIG. 2 Two thread material layers 1, 2, each manufactured by warp-knitting are shown side by side in Figure 2 A, and they are shown in Figure 2 B in a superimposed arrangement and twisted, with respect to their warp thread directions (represented by darker lines), by an angle ⁇ of, for example, 80 °.
  • the technical effect of the feature of a superimposed arrangement of the at least two (and preferably ⁇ 2) warp-knitted thread material layers twisted by an angle ⁇ of at least 20 ° with respect to their directions of the warp threads is twofold: From a safety point of view, the blocking of the operation of a chainsaw cutting into the cloth provided with the multilayer lining fabric in a (for example) vertical or diagonal direction (of trouser legs) is in a short time range comparable to, or even better than, corresponding values of prior art clothes, but the elasticity and stretchability of the multilayer lining fabric (comprising said warp-knitted thread material layers) is enhanced considerably.
  • a multilayer lining fabric of the above type as it is in accordance with the present invention, is fixed in trousers of chainsaw operators, and the trousers are subjected to the standardized chainsaw cutting tests in the directions perpendicular and parallel to the trousers' legs (so-called PPE test (or in German: EU PSA-Baumuster-Prüfung))
  • the multilayer lining fabric is capable of blocking the chainsaw's operation better than in cases of prior art trousers provided with lining layers superimposed in parallel, with respect to their twisted directions of warp threads of the plurality of layers. Details are described below in the experimental section.
  • the angle ⁇ of twist of the direction of warp threads of one layer with respect to the direction of warp threads of an adjacent layer is at most 120 °. If this upper limit value of the twist angle ⁇ is observed, the elasticity and stretchability of the multilayer lining fabric is also still enhanced. In multilayer lining fabrics having more than the minimum two warp-knitted thread material layers (e. g. having, for example, 6, 7 or 8 layers of the polymer thread material), the comfort for the user (particularly due to the enhanced elasticity and stretchability) is even better. A motion of the legs under heavy working duty and, hence, including a lot of sweating of the wearer in trousers provided with the multilayer lining fabric is achievable without the appearance of irritations or even inflammations on the wearer's skin.
  • the angle ⁇ of a twist of the direction of warp threads of one layer with respect to the direction of warp threads of an adjacent layer is within a range of 50 ° ⁇ ⁇ ⁇ 110 °.

  • the angle ⁇ of a twist of the direction of warp threads of one layer with respect to the direction of warp threads of an adjacent layer is within a range of 70 ° ⁇ ⁇ ⁇ 90 °.
  • the angle ⁇ of twist of the direction of warp threads of one layer with respect to the direction of warp threads of an adjacent layer is within a range of 80 ° ⁇ 5 °.
  • the elasticity and stretchability of the multilayer lining fabric is enhanced to a surprising extent.
  • multilayer lining fabrics having more than the minimum two warp-knitted thread material layers e. g. having, for example, 6, 7, 8 or 9 layers of the polymer thread material
  • the comfort for the user is excellent, compared to the prior art.
