Abstract: In the manufacture of polyamide filaments by melting polycaprolactam chips at 250 DEG -295 DEG C. under an inert gas at a pressure of 0,5-5 atmospheres and melt spinning the polyamide, the chips have been washed with water but not dried or only incompletely dried and contain over 1/4 % by weight of water and the polyamide is maintained in a molten condition for a period not exceeding in minutes the expression:- <FORM:0918930/IV(a)/1> in which e=the base of the natural logarithms, T=temperature in DEG C., P=pressure in atmospheres of inert gas, E=sum of the free amine and carboxyl end groups in the polymer expressed in gram equivalents per million grams. The determination may be carried out on a sample of the polymer taken from the melt pool or on a sample of the extruded filaments. The earlier stages of the washing of the chips may be carried out with aqueous solutions, e.g. of caprolactam, pure water being subsequently used. The time during which the polyamide is maintained in a molten condition is preferably not more than 80% of the specified maximum permissible period. The inert gas may be nitrogen, steam, helium or hydrogen, preferably steam at within 3% of the prevailing atmospheric pressure. It is preferable to use polyamide chips containing over 3 1/2 % of water, e.g. up to 7% or over provided their water content is not so high as to cause caking or paste formation.

Patent ES-269627-A1 (ES)
Title: Production of crimped yarns
IPC: D06M13/08
Filed: 1961-08-07
Abstract: Polyolefin, especially polypropylene yarn, at least partly formed of stretched continuous filaments, is crimped by subjecting the yarn to the action of a swelling agent, in the form of vapour or mist at a temperature near the boiling-point of the agent, for less than 20 seconds. Suitable swelling agents are aromatic hydrocarbons, e.g. toluene, hydroaromatic hydrocarbons, e.g. cyclohexane, decalin and tetralin, and chlorinated hydrocarbons, e.g. carbon tetrachloride, dichloroethane, tri- and tetrachloroethylene and chlorobenzene. The yarn is passed through a chamber containing the swelling agent under negligible tension. The yarn may be twisted prior to the swelling treatment, and may be heat-treated, e.g. in a steamoven, subsequent to it. The crimp obtained is 20 to 100%, preferably 30 to 45%, and is irregular. In an example, isotactic polypropylene yarn of 600 den., previously drawn 5,5 times its original length, travels in a path in the form of an acute V through a vertical cylinder, filled with trichloroethylene vapour. The top of the cylinder is open, and cooled by water, the bottom is connected to a container of boiling trichloroethylene. After an immersion time of 1 second, the yarn is of 960 den. and has a 37,5% crimp. Subsequent treatment by steam at 140 DEG C. for 1 hour stabilizes the crimp against tension.

Reaction (2) is preferably affected at a temperature up to 100 DEG C. with elemental bromine or chlorine, but other halogenating agents may also be used, e.g. N-bromosuccinimide, N - bromacetamide, sulphuryl chloride or N-chlorosuccinimide. Reaction (3) may be effected at 50-125 DEG C. in the presence of a solvent, which may be an excess of the dialkylamine. The products may be converted into salts, e.g. with hydrochloric, sulphuric, phosphoric, acetic, citric or benzoic acid. Examples are given of the manufacture of the hydrochlorides of a -diethylamino-o-, -m-, and -p-trifluoromethyl - propiophenones.
