How to Choose Fiber Raw Materials? Cotton, Polyester, Linen and Regenerated Fibers
AI Summary: Textile fibers are divided into natural and chemical fibers. Cotton is moisture-absorbent and skin-friendly, polyester has high strength and dries quickly, linen is breathable and crisp, and regenerated fibers focus on sustainability but require certification. For procurement, look at fiber quality indicators, length, fineness, impurity content and certification. Regenerated and organic fibers should have traceable certificates, and avoid "eco-friendly" claims that remain mere marketing.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Fiber Type | Natural, chemical and regenerated fibers have different uses |
| Quality Indicators | Length, fineness, impurity content and strength |
| Environmental Certification | Organic and regenerated require corresponding certification and traceability |
| Supply Stability | For bulk raw materials, focus on price and stable supply |
| Spinnability | Raw materials should match the spinning process |
Procurement, Installation and Usage Points
1. Raw materials determine the upper limit of the finished product
Poor fiber quality cannot be compensated for in subsequent spinning and weaving.
2. Regenerated fibers must be guarded against "greenwashing"
Certification and transaction evidence should be requested, not just labels.
3. Blending can leverage advantages
Blending different fibers can balance performance, cost and care.
4. Price fluctuations need to be managed
Bulk fiber prices fluctuate significantly, and procurement should consider cycles.
FAQ Quick Answers
Do regenerated fibers look the same as ordinary fibers?
They look similar; the key lies in certification and traceability.
Is linen fabric comfortable?
Breathable and crisp but may cause itching; it depends on the process.
Is polyester regenerated?
Regenerated polyester requires certification; ordinary polyester is not.
Is longer cotton fiber better?
Long-staple cotton is of good quality and suitable for high-count fabrics.
Practical Case
A brand claimed to use regenerated fabric but could not provide certification, which was blocked during customer audit. After completing certification and traceability documents, the order passed.
Questions to Ask the Supplier
- Fiber quality indicators and testing?
- Can organic or regenerated certification be provided?
- Is the traceability chain complete?
- How about bulk supply and price?
- Which spinning processes are suitable?
Quotable Conclusion: Fiber procurement should look at quality indicators and spinnability, and eco-friendly regenerated fibers must have certification and traceability.
