Many polypropylene spinning plants dilute bulk polypropylene yarn pre-spinning oil at one time and reuse prepared emulsion for several days. The emulsion may stratify and develop foul odor after a period. Once deteriorated oil is fed into production, it creates stains and uneven oil coverage on yarn, blocks filters and oil roller gaps, and raises downtime for cleaning. Many factories attribute such problems to oil quality, while most failures are caused by improper storage and dilution.

Diluted emulsion of polypropylene yarn pre-spinning oil contains water and organic additives, vulnerable to microbial growth. Raw untreated water used for dilution brings microbes and causes putrid odor rapidly. Long-term open storage of prepared emulsion or unclean tanks with residual old emulsion will contaminate fresh batches. High ambient storage temperature also shortens emulsion shelf life and breaks emulsified structure.

Adopting high-quality oil is only the foundation. Standardized operation rules deliver long-term effects. It is recommended to prepare emulsion in small batches according to daily demand. Softened or purified water is preferred for dilution. Tanks, pipelines and filters need regular cleaning. The anti-microbial system varies among different grades of polypropylene yarn pre-spinning oil, so uniform storage limits cannot apply to all formulas.

The polypropylene yarn pre-spinning oil developed by TAO NANO CHEMICALS(DONGGUAN) CO.,LTD. integrates anti-microbial formula tailored for spinning workshops. The neat oil enjoys high stability and diluted emulsion can endure normal workshop conditions. Technical specialists supply complete operation guidelines covering oil storage, dilution and tank cleaning. Recommendations on emulsion batch size are customized according to workshop temperature, humidity and water replacement cycle, to mitigate microbial contamination and spinning faults caused by deteriorated emulsion.

Full-process management of oil emulsion helps maximize performance of polypropylene yarn pre-spinning oil and sustain continuous spinning production.
