Raw material storage cycle is a neglected key factor affecting mother yarn splitting machine production quality. Long-term improper storage changes the physical properties of polyester mother yarn and nylon mother yarn, bringing unstable quality risks to tex mono split mono filament production.
Polyester mother yarn has stable physical properties with a valid storage cycle of 12 months under standard environment. After exceeding 12 months, fiber surface aging occurs, increasing mono filament breakage rate by 4.3% during splitting processing.
Nylon mother yarn is more sensitive to storage time and environment. The optimal storage cycle of nylon raw yarn is 8 months. Long-term storage causes fiber moisture loss and brittleness increase, seriously reducing splitting yield.
Long-stored mother yarn has uneven internal stress distribution. Fiber stress accumulation leads to irregular shrinkage after splitting, resulting in tex value drift of finished mono filament after winding and storage.
Batch production management needs to follow first-in first-out rules. Data shows factories implementing FIFO rules reduce storage-related quality defects by 38% compared with random yarn usage modes.
Sealed storage effectively isolates air and moisture erosion. Unsealed stored mother yarn absorbs dust and moisture, causing surface friction coefficient change and unstable feeding during mother yarn splitting machine operation.
Temperature fluctuation in storage warehouse accelerates raw material aging. Long-term temperature alternation above 5℃ will damage fiber structure consistency and affect tex mono split splitting uniformity.
Lanxiang technical team recommends classified storage schemes for polyester mother yarn and nylon mother yarn, matching different storage cycles and environmental standards to maximize retention of original fiber performance.
Timely quality inspection of overstocked raw materials is necessary. Sampling test before use can screen aging and deteriorated mother yarn, avoiding large-batch defective mono filament production.
