Occupations | Tends $T3range$T1 that mercerizes and dries yarn in warp form: Pours caustic soda, acids, and softeners into mixing tanks, according to formula. Turns valves to allow solutions to flow into mercerizing, neutralizing, and finishing vats. Mounts balls of warp yarn in creel, using hoist or lift and aid of YARN-MERCERIZER-OPERATOR HELPER (textile). Ties ends of warp to leader, starts machine, and observes movement of warp through baths to detect breaks or tangles. Pulls broken yarn from vat, using hook, and ties ends. Tests caustic solution, using hydrometer, and adds water or caustic to restore solution to prescribed strength. Adjusts controls to regulate water and drier temperature and speed at which yarn passes through machine, according to yarn type. May tend discharge end of drier and observe yarn passing through $T3swing-folding attachment$T1 into handtruck, boxes, or cans. May oil and make minor adjustments and repairs to machine.

| Tends machine that adds silk-like luster to cotton cloth and increases strength and affinity of cloth for dyes: Mounts roll of cloth on machine or pulls supply cloth from handtruck or overhead poteyes and sews end to leader in machine, using portable sewing machine. Turns valve to admit caustic into vats and handwheel to adjust $T3tenter frame$T1 clips to maintain tension on cloth and prevent shrinkage as cloth passes through soapy-water spray. Sets thermostat to control temperature of caustic bath. Starts machine and observes flow of cloth through machine units to detect holes in cloth and torn selvages. Cuts out defects, using scissors, and seams ends of cloth. Turns knobs on control panel to synchronize motor speeds of machine units. Adds soap to wash bath as suds are depleted. (references) | |
| Tends machine that mercerizes yarn in skein form: Shakes skeins of yarn to remove tangles and loads skeins on roller arms of machine. Starts machine that puts yarn under tension, passes skeins through caustic solution, and rinses skeins. Tests caustic solution, using hydrometer, and adds soda or water to maintain uniform strength as specified. Removes skeins from mercerizer and hangs skeins on rack of tank for neutralizing. Turns valves to start spray of water and neutralizing solution. Tests neutralization, using litmus paper. May weigh and mix caustic and neutralizing solutions according to formula. May extract moisture from yarn [EXTRACTOR OPERATOR (textile)] and dry yarn in steam chamber [SKEIN-YARN DRIER (textile)]. (references) | |
