Definitions

  • a cloth of high tensile and tearing strength is often used for technical purposes, such as tarpaulins, canopies, air-inflated structures and the like but also for many other products.
  • Such a cloth comprises a ground fabric of multi-fibre, approximately equally coarse threads of polyamide, polyester or other synthetic material of high tensile strength, which are interwoven with approximately the same set of warp and weft, the finished ground fabric being coated with a plastics or elastomer material, such as polyvinylchloride, polyurethane or a polymer of 2-chlorobutadiene. It is desired, with a given fabric weight per surface area, to obtain optimum strength properties of the coated fabric. To attain optimum strength properties it is essential to reach a balance of the tensile strengths in the warp and weft directions and at the same time a balance of the tearing strengths over warp and weft.
  • the object of the present invention is to eliminate the above-described problems encountered in providing balanced optimum strength properties in a cloth intended for technical purposes, such as tarpaulins, canopies, and the like, of the type indicated in the preamble of the appendant claim.
  • the threads are interwoven in a weave pattern the repeat of which comprises six warp threads and six weft threads, the first and fourth weft threads passing over the first, second, fourth and fifth warp threads, the second weft thread passing over the first, third and sixth warp threads, the third weft thread passing over the second, third and sixth warp threads, the fifth weft thread passing .over the third, fourth and sixth warp threads, and the sixth weft thread passing over the,third, fifth and sixth warp threads.
  • the invention is based on the observation that it is possible, in connection with the plastics coating of ground fabrics, to attain balanced strength properties in the finished cloth by using for the manufacture of the ground fabric of the cloth a weave pattern that has been especially designed for the purpose.
  • Said weave pattern is illustrated in the accompanying drawing.
  • Each small square of the drawing corresponds to a point of cross-over of a warp thread and a weft thread, every horizontal row of squares thus corresponding to a weft thread and every vertical row of squares corresponding to a warp thread.
  • the crossed squares indicate that the warp thread at the respective cross-over point passes over the weft thread, while every empty square implies that the weft thread at the respective cross-over point passes over the warp thread.
  • thicker lines define a square comprising six warp threads and six weft threads. This is the pattern repeat for the weave pattern in question.
  • the portion of the fabric pattern illustrated in the drawing comprises four pattern repeats for a clear showing of the nature of the pattern.
  • the repeat of the weave pattern illustrated in the drawing comprises, as mentioned above, six warp threads and six weft threads.
  • the first and fourth weft threads pass over the first, second, fourth and fifth warp threads
  • the second weft thread passes over the first, third and sixth warp threads
  • the third weft thread passes over the second, third and sixth warp threads
  • the fifth weft thread passes over the third, fourth and sixth warp threads
  • the sixth weft thread passes over the third, fifth and sixth warp threads.
  • Cloths having a ground fabric of the 2-end type, warp-rib type, 2/2 dice type and a ground fabric with a weave pattern according to the present invention were manufactured for illustration of the effect of the invention.
  • the same yarn was employed for all ground fabrics, and the yarn was used for both the warp and the weft of the fabrics.
  • the different ground fabrics were then coated with a plastics coat of the same kind and in the same manner, after which the finished cloths were subjected to tensile strength tests (5 cm wide strips) in both the warp and the weft direction as well as to tearing tests over both the warp and the weft.
  • the results will appear from the following Table.
  • the Table shows that the cloth according to the invention had equally good and balanced tensile strengths in the warp and weft directions as the cloths having a weave with 2 ends and warp rib, but the tearing strengths over warp and weft were practically the same and substantially higher (approximately 100% or more) than the tearing strength in the poorest direction for the said two other cloths, simultaneously as the grammage and thickness of uncoated fabric and the set were practically the same in the three cases.
  • the cloth having a ground fabric of 2/2 dice weave it should be observed that the tensile strengths and the tearing strength over the warp certainly were higher than for the cloth according to the invention, but the tearing strength over the weft was somewhat lower.
