- Spinning Cotton Combed Yarns from Slivers Processed on a High-Production Card
抄録
Cotton slivers delivered from a high-production card, Toyoda CK-7C, at production rates of 35, 50, 70 and 100 lbs/hr were processed on three kinds of pre-comber process with different combination of draftings, and then spun into 12, 18, 30 and 40s combed yarns. The yarns were compared with those processed on a conventional card at a production rate of 10 lbs/hr.<BR>The carding waste was much lower on the high-production card than on the conventional card. The slivers from the high-production card contained less trailing or majority hooks and more leading or minority hooks than the slivers from the conventional card.<BR>It was supposed that this tendency would increase the comber noil, but the noil did not increase if the sliver was processed on a pre-comber process with higher drafting ratio in such a direction that the leading hooks might be reduced. By this means, the cotton material may be saved by the processing on the high-production card for combed yarn in a similar way to the case of processing the carded yarn.<BR>Increasing the production rate of the card up to 100 lbs/hr did not at all affect the quality of coarse combed yarn up to 20s. Nor did it affect the tensile strength or the irregularity of 30 or 40s combed yarn, but it affected slightly the imperfection counts of the yarn. However, no difference at all was found in quality between combed of 30s or 40s yarns processed on the high-production card at 50 lbs/hr and yarns of the same count processed on the conventional card at 10 lbs/hr.
