Definitions

  • the present invention relates to sewing thread made of man-made filaments of synthetic material, for example nylon.
  • Man-made filaments are made by extruding liquid material through a spinneret provided with holes, and solidifying the liquid material.
  • the solid product from one hole of the spinneret is a filament.
  • a thread comprises a number of such filaments twisted together.
  • sewing threads made from synthetic materials consist of a substantial number of filaments twisted together, for example as many as two hundred filaments.
  • a very fine thread may consist of two yarns twisted together and having a total of twenty-four filaments.
  • the filaments in multi-filarnent sewing threads are usually finer than 6 denier.
  • a 120 denier thread may consist of two yarns each having twenty filaments of 3 denier each, or forty filaments of 1 /2 denier each, whilst a coarser thread of 630 total denier may-consist of three yarns each having one hundred and forty filaments of 1 /2 denier each.
  • the surfaces of the filaments within such threads scatter the light to such an extent that little if any light is transmitted through the thread. Such a thread in a seam appears white, if the filaments therein are colourless.
  • sewing thread comprises not less than two and not more than six substantially transparent or translucent and colourless or nearly colourless filaments of synthetic material twisted together.
  • a further feature of the invention resides in sewing thread comprising not less than two and not more than four such filaments twisted together.
  • a still further feature of the invention resides in sewing thread comprising not less than three and not more than six such filaments twisted together.
  • the sewing thread of the present invention has a breaking strength of at least 250 gms. when tested in accordance with British standard specification No. 1932.
  • the filaments are preferably twisted together at from four to eight turns per inch and the twisted filaments may be heat set.
  • seams sewn wtih sewing thread of the invention the thread tends to take on the colour of the fabric into which it is stitched and this property of the thread is substantially independent of the denier of the filaments.
  • threads made according to this invention and the seams formed with them are not unduly stiff. This not only facilitates sewing, but it also has the advantage that the thread in the stitched seam lies closer to the fabric. Seams therefore sewn with thread made according to this invention tend to be generally less visible than seams sewn with the known multi-filament threads hereinbefore discussed or even with single filament threads.
  • the threads also can absorb more lubricating material when treated with lubricants than single filament threads.
  • the present invention further consists of a method of manufacturing sewing thread by twisting together two or more, but not more than six, filaments of colourless or nearly colourless and substantially transparent or translucent synthetic material.
  • the twisting may be carried out at the same time as the filaments are extruded but as a rule without adhesion between the filaments.
  • Suitable synthetic materials for the manufacture of sewing thread according to the invention include polyester filaments such as those sold under the registered trade mark Terylene, and also polypropylene, but we prefer to use nylon, for example of the type sold as nylon 6 and 66, because of its combination of properties-high melting point and strength with good flexibility-all of which are very desirable in sewing thread.
  • the denier of the threads and filaments and the number of filaments of the threads of the present invention should be chosen according to the use which is to be made of them.
  • satisfactory nylon sewing threads made according to the present invention for particular purposes are as follows:
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than three and not more than four substantially transparent and colorless filaments of synthetic material twisted together, said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than three and not more than six substantially transparent and colorless filaments of synthetic material twisted together, said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than two and not more than four substantially transparent and colorless filaments of synthetic material twisted together, said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than two and not more than six substantially transparent and colorless filaments of synthetic material twisted together, said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than two and not more than six nylon filaments twisted together at from four to eight turns per inch, said twisted together filaments being in a set condition, said filaments being transparent and colorless, and said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than two and not more than four nylon filaments twisted together at from four to eight turns per inch, said filaments being in a set condition, said filaments being transparent and colorless, and said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than three and not more than six filaments twisted together at from four to eight turns per inch, said filaments being in a set condition, said filaments being transparent and colorless, and said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than three and not more than four nylon filaments twisted together at from four to eight turns per inch, said filaments being in a set condition, said filaments being transparent and colorless and said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • Sewing thread adapted to take on the color of a fabric to which said thread is stitched comprising not less than two and not more than six substantially translucent filaments of synthetic material twisted together, said filaments being of such a thickness that when twisted together they make a thread suitable for sewing.
  • a method of making a sewing thread which when stitched to a fabric takes on the color of said fabric comprising:
  • Sewing thread according to claim 4 comprising filaments of nylon.
  • Sewing thread according to claim 9 comprising filaments which are pigmented lightly with black pigment.
  • Sewing thread according to claim 9 comprising filaments twisted together at from four to eight turns per inch.
