ABSTRACT:
In a process and apparatus for bulking, more particularly high-bulking, of textile yarns having fibers of different shrinkage characteristics including the step of and apparatus for temporarily heating the yarn sufficiently to obtain differential shrinkage and thus bulking of the yarn; the improvement of the steps of and apparatus for soaking the yarn with water and/or other liquid having dielectric properties similar to water while fully and evenly saturating the yarn throughout with a predetermined amount of such liquid, and applying microwave energy to the saturated yarn for heating of the yarn. With this process and apparatus, heating is uniformly applied throughout the yarn and an energy savings can be realized over conventional yarn bulking processes. This process and apparatus may be utilized in conjunction with a two-for-one yarn twisting apparatus in which the process is carried out and the apparatus is disposed between the steps of and the apparatus for twisting and taking-up of the yarn.
