Gut Rubber and Extruded Latex. The manufacturing technology for cut and extmded mbber thread is much older and more widely known than that for spandex fibers. Because production faciUties can be installed with relatively modest capital investment, manufacture of mbber thread is fragmented and more widely distributed with a few major and many minor producers. On a worldwide basis, Fikattice of Italy is the largest mbber thread producer with modem extmded latex plants in Italy, Spain, Malaysia, and the United States. Second in production capacity is the Globe Manufacturing Co., Fall River, Massachusettes with production operations in the United States and the UK. These firms also produce spandex fibers. 

Uses NR latex for adhesives, dipped goods, coatings, extruded rubber thread... 

Most extruded latex fibers are double covered with hard yams in order to overcome deficiencies of the bare threads, such as abrasiveness, color, low power, and lack of dyeabiUty. Dining covering, the elastic thread is wrapped under stretch, which prevents its retimi to original length when the stretch force is removed thus the fiber operates farther on the stress-strain curve to take advantage of its higher elastic power. Covered mbber fibers are commonly found in narrow fabrics, braids, surgical hosiery, and strip lace.
