Date：2026-08-26Yarn got moldy? It is a fear for every yarn and weaving factory – moldy yarn rolls mean wasted yarn and contamination of downstream fabric. This article explains yarn mold remover usage and raw material prevention with specific parameters.
1. Why Does Yarn Mold Easily?
- Natural fiber absorption: cotton regain 8.5%; mold starts above 8% moisture;
- Size residue: starch-based sizing feeds mold;
- Rolled packaging: cone cores trap humidity (12%+), molding from inside;
- Warehouse: humidity above 65% with poor ventilation puts the whole warehouse at risk.

2. How to Treat Moldy Yarn
- Isolate: remove moldy cones immediately;
- Treat: soak or spray with yarn mold remover, sit 15-30 minutes;
- Rinse and dry: rinse, dry at ≤80°C (avoid fiber damage), reduce to ≤7% moisture;
- Recheck: confirm no spots, no odor, strength ≥90% of original.

3. Prevention Plan (Prevention First)
| Stage | Measure | Parameters |
|---|---|---|
| Intake | Test moisture | Cotton ≤7%; dry first if exceeded |
| Production | Dry after sizing; add anti-mold to size | 0.1%-0.3% in size |
| Warehousing | Control humidity | ≤60%, off floor/walls |
| Packaging | Sachets in bags/boxes | 1 sachet per 10kg |
4. FAQ
Q1: Does treated yarn lose strength?
A: Correct processing (≤80°C, controlled time) keeps loss within 10%; severely moldy yarn should be scrapped.
Q2: Will the agent bleach colors?
A: Choose colorless, color-fast agents; test dark yarns first.
Conclusion
Yarn got moldy? Control moisture (≤7%), add anti-mold (0.1%-0.3%), ventilate warehousing (≤60%). For products or plans, contact us or read Webbing Got Moldy?
