摘要： PURPOSE: To obtain the subject tow good in a cutting property and capable of preventing the generation of curl in a thermal hysteresis-receiving process such as a dyeing process in good productivity by thermally treating the non- drawn tow of nylon 6 under a specific condition and subsequently drawing the treated tow. CONSTITUTION: This method for producing a nylon 6 tow for electric flocking comprises melt-spinning nylon 6 polymer, cooling the spun fibers into the solid fibers, thermally treating the fibers in a hot water bath heated at a higher temperature (preferably >=45 deg.C) than the glass transition point of the polymer, and subsequently drawing the treated fibers. The time for the thermal treatment in the hot water bath is >=0.5sec. The tow does not cause the shortening in the life of a blade when cut into short fibers, is good in a straightening property when dyed or dried after the cutting process, and is also good in a coloring property.

摘要： PURPOSE:To obtain the high-quality polyamide tow with animal hair-like touch, having good stretch breaking nature by melt spinning of nylon 66 dope followed by cooling and solidification and then oiling the resultant fibers with a lubricant containing both surfactant and inert fine particles so as to result in a specified amount of the inert fine particles attached to the fibers. CONSTITUTION:Nylon 66 dope containing 0.25wt.% of titanium dioxide is put to melt spinning through a spinneret heated to 285 deg.C and taken up at a speed of 1200m/min to form an undrawn subtow. A plural number of such subtows are then put in parallel into an undrawn tow, which is, in turn, put through a bath where a lubricant containing a surfactant (e.g. lauryl alcohol-based phosphoric ester potassium salt) and inert fine particles (e.g. silica) is placed, to provide oiling treatment. Thence, the resulting tow is put in between a pair of rubber nip rollers to control the pickup of the inert fine particles on the fibers so as to come to 0.1-1.0wt.% based on the fibers. Thence, the tows are drawn in steam by a factor of 3.5 and heat treated on a drum at 170 deg.C and then crimped, thus obtaining the objective polyamide tow
