Abstract: PURPOSE:To obtain the title yarn useful for clothes, etc., having low shrinking characteristics of washing by subjecting polyamide to melt spinning, cooling and solidifying, supplying the yarn with a finishing oil, drawing the yarn between a take-off roll and a heated draw roll, heat-treating under a specific condition and winding at high speed. CONSTITUTION:In producing yarn having 1.5g/d stress S (g/d) at 15 % elongation by direct spinning and drawing method wherein yarn Y prepared by melt spinning of polyamide is cooled and solidified by a cooler 1, provided with a finishing oil by a finishing oil supplying device 2, wound on a take-off roll 3 by a semicircle, successively on a draw roll 4 having 90-215 deg.C surface temperature by a semicircle, drawn at =3,500m/minute, the heat treatment is carried out under a condition of T shown by the formula [T is index of heat treatment; TH is surface temperature ( deg.C) of draw roll; TL is atmosphere temperature ( deg.C) in draw part; t is contact time (second) of yarn with draw roll; de is fineness (denier) of single yarn of wound yarn] of 90-40(S+1) to give the objective yarn.

Abstract: PURPOSE:To improve the moldability of polyamide pellets, by applying a small quantity of an alkylene oxide addition product of a compound, which has a functional group capable of undergoing addition reaction with an alkylene oxide, onto the surfaces of the polyamide pellets. CONSTITUTION:An aliphatic, cycloaliphatic or alkyl group containing aromatic compound (for example, butyl alchol, cyclohexyl alchol and nonyl phenol) with four or more carbon atoms and having a functional group (for example, an amino group, carboxyl group, hydroxyl group, amide group, etc.) capable of undergoing addition reaction with an alkylene oxide is subjected to addition reaction with an alkylene oxide (for example, ethylene oxide or propylene oxide) to prepare an alkylene oxide addition product or its deriavative. The resulting addition product is applied in an amount of 5-100ppm onto the surfaces of polyamide pellets (for example of nylon 6, nylon 12 or the like) to obtain the captioned polyamide pellets.
