    摘要: The invention relates to a control system for a tufting machine configured for forming tufted carpet. The tufting machine can have a system controller in communication with the tufting machine and with a plurality of yarn feed controllers for controlling operation of yarn feed motors that are configured to supply yarn from a source of yarn to the tufting machine. The system controller is programmable to enable input of a plurality of predetermined yarn feed profiles for selected stitches of a programmed pattern to be tufted such that, although at least two of the predetermined yarn feed profiles can be different, substantially the same feed length of yarn is used from each of the plurality of yarns.

    摘要: The present invention relates to latex compositions comprising hydroxyethyl cellulose grafted acrylic polymer emulsions and methods for preparing same without gelling or coagulation. The latex composition comprises at least about 0.2% of HEC by weight relative to the monomer weight, contains at least about 45% solid, and the average mean volume (mV) latex particle size is in the range of about 320-about 850 nm. Paint compositions incorporating the HEC grafted acrylic latex show high viscosity at static conditions and have no color flow and no syneresis compared paints containing a latex without HEC grafting. The present invention also relates to a cross-linking mechanism that cross-links latex particles at ambient conditions. This cross-linking mechanism comprises diacetone acrylamide (DAAM) and methacrylamide (MAM) with or without styrene.
