Fabric Finishing: Shrinkage, Pilling and Environmental Compliance
AI Summary: Fabric finishing can improve shrinkage, pilling, wrinkle resistance, water repellency, flame retardancy and hand feel. Pre-shrinking reduces garment shrinkage; brushing, coating and calendering change the style; functional finishes should be evaluated for durability and environmental safety. Procurement should specify the finishing purpose, test methods and performance after washing to avoid functionality that only works on new products.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Pre-shrinking finish | Reduces shrinkage and deformation |
| Anti-pilling | Improves pilling grade and durability |
| Functional durability | Retention of water repellency, flame retardancy, etc. after washing |
| Hand feel and style | Softening, brushing, coating, etc. selected as needed |
| Environmental safety | Finishing agent residues must meet standards |
Procurement, Installation and Usage Points
1. Functional finishes must be tested for wash durability
If water repellency, stain resistance and other functions fail after a few washes, their value is limited.
2. Softness may come from auxiliaries
Excessive softening finishes require attention to environmental compliance and durability.
3. Coating affects breathability
Windproof and waterproof coatings reduce breathability and should be balanced according to the end use.
4. Shrinkage testing is indispensable
Fabric shrinkage rates should be established before garment production.
FAQ Quick Answers
Is pre-shrinking necessary?
It can significantly reduce the risk of garment shrinkage.
Is waterproof fabric permanently waterproof?
Most performance declines with washing and abrasion.
Can pilling be completely avoided?
It can be reduced through finishing and fiber selection.
Is coated fabric breathable?
Breathability typically decreases; check the specifications.
Case Study
A brand claimed its jacket was waterproof, but after several washes it no longer repelled water. After switching to a wash-durable finish and clearly specifying washing and care instructions, customer expectations became more reasonable.
Questions to Ask the Supplier
- Finishing items and wash durability cycles?
- Shrinkage and pilling tests?
- Environmental testing of finishing agents?
- Breathability specifications of coatings?
- How is functional failure determined?
Quotable Conclusion: Fabric finishing should focus on shrinkage, pilling and functional wash durability, with verification of environmental safety and actual test results.
