in the manufacture of umbrellas, core spun threads made from polyester and cotton/polyester are used almost exclusively. They are far superior to conven- tional threads made from cotton with regard to tensile strength, abrasion resistance, decay resistance and other important characteristics.
We use stitching density by 30 % (e. g. from 3 to 4 stit- ches/cm (0.4 inches)) increases the strength of the seam by 30 %. An increase in stitch density thus often enables the use of a finer thread.
In our production of umbrellas, a very high stitch density of 7 stitches/cm will have to be observed because the roof of the umbrella must be able to withstand high tension.
