    Abstract: A rolling guide for a fiber strand comprises a first support member extending from a base of the roller guide to a compound joint having first and second portions. The first portion of the compound joint is mounted on the first support member for rotation around a first axis. The second portion of the compound joint being rotatable relative to the first portion around a second axis at a compound angle to the first axis. A second support member is connected with the second portion of the compound joint at a proximal end of the second support member. A channeled roller is carried on the second support member distally from the proximal end, and mounted for rotation around a third axis. The channeled roller has an annular channel formed therein. A fastener is provided to selectively prevent the second portion of the compound joint from rotating around the second axis relative to the first portion of the compound joint. Also provided according to the present disclosure is a method of guiding one or more fiber strands from a fiber package on a creel device to a destination location for further processing.

    Abstract: Disclose are methods for minimizing the recycle of para-toluic acid within a terephthalic acid purification plant. Specifically, the disclosed methods remove a portion of the p-toluic acid from the pure plant flash condensate and recycles a portion of this cleaned stream back to the crude TA feed stream before the pure plant process. This process allows the 4-CBA in the crude TA to be increased from below 3000 ppm to between 3000 ppm to 4000 ppm without increasing p-toluic acid in the PTA, resulting in an about 7% increase in the pure plant mother liquor flows.

    Abstract: Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
