Abstract: 841,228. Sewing threads. DU PONT DE NEMOURS & CO., E. I. March 24, 1958 [March 27, 1957 (4)], No. 9380/58. Drawings to Specification. Class 120(3). A sewing thread intended to reduce or eliminate seam puckering is formed of fully synthetic fibres which have a yield strength for 15 % permanent deformation of less than 0À1  grams per denier at 160‹C. One suitable yarn is composed of polyethylene terephthalate filaments which have been drawn following extrusion with a ratio of 2À937 and passed through a steam oven at 100 ‹C. wherein they are permitted to shrink by 44 % and are then twisted and plied. The resulting thread is said to exhibit 22% spontaneous and irreversible extension when heated at 160‹C. for six minutes without tension and is utilised as the bobbin thread in association with a standard polyethylene terephthalate sewing thread for seaming nylon taffeta fabric by machine. In a further example, the above extensible thread is dyed under pressure at 110 ‹C., whereafter the property of spontaneous extensibility is lost but the yield strength remains low and the tendency to pucker is less than normal in a seam utilising such a yarn. Specification 841,230 is referred to.
