Mechanical processing of the chemically treated samples

During the first passage through the flat top card, the web broke several times. The brownish chemically-treated fibers remained entangled in clusters, whereas 

After carding, the fibers were drawn twice and then ring spun into yam. The spinning process was difficult because the yams frequently broke, as will be seen by comparing these results with those obtained when spinning the 80% new acrylic/20% recycled blend (not chemically treated) described earUer. The spinning performance of chemically treated materials compared to non-treated is shown in Table 10.5. 

Based on these resnlts it was decided not to proceed with additional experiments with chemical treatments, but to concentrate on improving the separation of the fibers by mechanical means. 

This experiment is similar to Experiment 1, in which an 80/20 blend was produced using fibres that were not chemically treated. However, this time the recycled fibers were double-carded on the roller top card for better opening. The yield (i.e. 

The record of the spinning trial of these fibers is as follows the yam broke after running for intervals of 2, 107, 33, 80, 180, 18 and 17 seconds, worse than the performance of the 80/20 blend.
