Spinning, weaving, dyeing and garment plants.
Lubricant on the yarn causes fabric defects; spinning frames run at high speed; stenters run hot; knitting needles need a washable, non-staining oil; yarn quality depends on the aprons and cots in the drafting system.
stenter treated; the plant has several machines of the same type, so the procedure had to be repeatable. Objective: clean the carbon deposits from the chain and guide rails of an 8-chamber stenter before switching to LUBCON TURMOFLUID 40 B chain oil, with a procedure that can be repeated on the other machines: mechanical cleaning, spraying the cleaning oil LUBCON TURMOWOODOIL MKP Cleaner at the chain's working temperature in several rounds, blowing with compressed air, then changing the oil.

Textiles · Dong Nai · 2017Work Hop Tien has done at plants in this industry, and technical articles on the lubrication points this industry meets most.
Objective: get data from real machines before changing grease: how long LUBCON grease stays on the draw-frame rollers compared with the grease in use, and which grease suits the spindle bearings of the ring frames (spindle speed about 19,500 rpm) and the open gears. Result: on the draw-frame rollers the LUBCON grease was still in place after at least 18 days (when the trial was stopped), compared with about 9 days for the grease in use; the open gears and the ring-frame spindle bearings were stable after two weeks by observation.

Objective: verify the hydrocracked mineral air compressor oil CPI-9370-46 under air-compressor conditions in Vietnam (hot discharge, dusty and humid compressor rooms) and use oil analysis to set the change interval for each machine. Six machines at three plants were monitored; this article presents three representative machines. Result: the normal samples held a viscosity of 44–50 mm²/s, within ISO VG 46, and a TAN below 0.5 mg KOH/g up to almost 5,000 hours; the 75 kW machine went on to 7,612 hours on one fill when monitoring ended (last analyzed sample at 4,872 hours); one case of water entering the oil was detected early through routine sampling and dealt with.
Binh Duong (now Ho Chi Minh City), North Central Vietnam, Dong Nai · Aug 2022 – Jul 2023Which oil your screw compressor needs is written on the machine itself: the manual, the oil label on the door and the discharge temperature under load. How to read all three and decide when to change the oil.
TechnicalTrade names change; base oils do not. How the four base oils in rotary screw compressor oil behave in Vietnamese conditions, why they cannot be mixed, and a table of which switches need a drain and which a full flush.
