摘要： A two-stage hydrolysis process for polymerizing epsilon-caprolactam is disclosed comprising a first stage from a temperature of about 180.degree. C.-260.degree. C., a pressure of 20 to 150 psig, for a period of about 0.5 to 4 hours, then before equilibrium conditions are reached a second stage at a temperature of about 200.degree. C.-260.degree. C., a pressure of about 100-900 Torr for a period of about 2 to 15 hours, while continuously removing most of the water so that water is removed both during hydrolyzation and during the subsequent polycondensation, whereby the cyclic dimer content of the shaped polymer article is below 0.2 percent by weight.

摘要： An improved high speed process for texturing continuous filament yarn is provided wherein the improvement comprises cooling the yarn, subsequent to texturing and prior to applying tension, by contact for at least 4 milliseconds with a curved surface at a temperature of -29.degree. to 2.degree. C. and an RMS of up to 10, frictional forces creating a yarn tension of 0.036 to 0.45 gram per denier per end at the surface. Apparatus is also provided for cooling the continuous filament yarn subsequent to texturing and prior to applying tension. The apparatus comprises a curved surface having a minimum length for yarn contact of 7.6 cm, an RMS of up to 10 and a temperature of -29.degree. to 2.degree. C. Textured yarn brought into contact with the surface for at least 4 milliseconds at a yarn tension of 0.036 to 0.045 gram per denier per end is cooled to increase yarn stability and prevent pullout of yarn texture.
摘要翻译：提供了一种用于纹理连续长丝纱线的改进的高速方法，其中改进包括在纹理化之后和在施加张力之前通过在-29°至2°的温度下与曲面接触至少4毫秒来冷却纱线 C.和RMS高达10，摩擦力产生0.031至0.45克/平方米/旦在表面每端的纱线张力。还提供了用于在纹理化之后和施加张力之前冷却连续长丝纱线的装置。该装置包括具有7.6cm的纱线接触的最小长度，高达10的RMS和-29°至2℃的温度的曲面。织构纱与表面接触至少4毫秒，冷却纱线张力为0.036至0.045克/旦，以增加纱线的稳定性并防止纱线纹理拉拔。

摘要： A dispersion is provided for incorporation with a synthetic fiber-forming polymer. The dispersion comprises a polymer additive, such as titanium dioxide, and a glyceride which is non-resin forming when exposed to certain temperatures and pressures for specified time periods and which has an average molecular weight of between about 600 and 2400.
