A specially designed multifilament textured yarn has alternating twists therein. A woven or knitted fabric manufactured from the yarn has a handling similar to that obtained by a hard twist yarn or a true twist yarn and provides pattern with a heather like feeling. In the yarn, S-twist yarn portions and Z-twist yarn portions are alternatingly distributed along the length of the yarn but the non-twisted portion is substantially not included in the yarn. Either S-twist yarn portions or Z-twist yarn portions have a compact twist yarn structure, and the other portions have a bulky twist yarn structure.

This invention relates to a novel spun yarn composed of staple fibers only and having the average number of fibers in cross section and the rate of yarn evenness being within a limited range, and a process for manufacturing the same directly from continuous multi-filament yarn.

A method of and apparatus for controlling spinning machines comprising circulating a working machine having a detector along a rail for monitoring the running conditions of the spinning machines in which a transmitter provided in the working machine transmits a first information signal indicating the nature of possible abnormal conditions of each spinning machine to a remote station having a receiver and a computer. In the receiver, a second information signal is generated and successively stored in registers depending on the nature of the abnormal conditions in accordance with the first information signal received. The computer reads the contents of the registers only when an interrupt signal is generated which indicates that an abnormal condition has occurred in a particular spinning machine. The computer memory tabulates these data and updates the data each time the working machine circulates around the spinning machines. Thus, by counting the data in the memory, the running conditions of the spinning machines can be effectively monitored. Furthermore, the number of inputs to the computer can be effectively reduced by limiting the input data to the computer to a minimum.
