    摘要: Disclosed herein are a highly uniform spandex and process for making such spandex. More particularly, the polyurethaneurea of which such spandex is prepared has both dialkylurea and cycloalkylurea ends, wherein a chain terminator composition includes a dialkylamine such as diethylamine and a cylcoalkylamine such as cyclohexylamine.

    摘要: A fiber of a polyurea wherein at least about 97 mole percent of its recurring units have the formula

    AND FROM 0 TO ABOUT 3 MOLE PERCENT OF ITS RECURRING UNITS HAVE THE FORMULA

    WHERE Z is a selected divalent organic radical, and at least about 69 percent of the

    GROUPS HAVE BOTH

    GROUPS IN THE TRANS CONFIGURATION. The fibers can be used to produce fabrics having good wash-wear and ease-of-care properties. The polymers can be prepared by reacting PACM with urea or PACM with PICM, and a small optional amount of H2N-ZNH2.

    摘要: A METHOD OF TREATING FILAMENTARY MATERIALS FORMED FROM DIFFICULTLY MELTABLE POLYMERS (AMIDE) AND PARTICULARLY TO THE STEP OF RELAXING THE SHAPED WET FORMED FILAMENT BY CONTACTING THE FILAMENT FOR A PERIOD OF TIME AND AT A TEMPERATURE SUFFICIENT TO IMPROVE THE DYE RECEPTIVITY OF THE FIBER WITH A STRONG INORGANIC ACID SHRINKING AGENT OF A SPECIFIED CONCENTRATION. MORE PARTICULARLY, AQUEOUS SOLUTIONS OF SULFURIC ACID, HYDROCHLORIC ACID AND PHOSPHORIC ACID ARE USED AS THE SHRINKING AGENT.
