TY - JOUR AU - Averkiev, B. AB - The LMC content in the Anid (K, %) was calculated from the equation 2.5C K-- where q is the weighed portion of Anid (g). The rms deviation of the measurements of the LMC content did not exceed 0.14%, and the relative rms deviation 0.10. The discrepancy between the interferometric and gravimetric methods of determining the LMC is :~5%. LITERATURE CITED 1. J. Rothe and M. Rothe, Macromol. Chem., 68, 206 (1963). 2. J. J. Burke and T.

Averkiev UDC 677.494.674.021.125.3 In the orientation-stretching process polyester fibre undergoes deformation in two stages, viz., deforma- tion by necking at a constant load in the first, and deformation under an increasing load as stretching continues in the second. On existing draw twisters equipped with two heaters (i.e. the top draw roll and a flat heating unit) the stretching process develops in such a manner that the major part of TI - Orientation stretching of polyester filament yarn JF - Fibre Chemistry DO - 10.1007/BF00546840 DA - 2004-10-13 UR - https://www.deepdyve.com/lp/springer-journals/orientation-stretching-of-polyester-filament-yarn-Z3FyFGuJwT SP - 502 EP - 503 VL - 8 IS - 5 DP - DeepDyve ER -
