Common problems with composite fabrics
Common problems with composite fabrics
1. Fabric color
01. During the lamination process, gluing, hot pressing, drying and other processes have an impact on the color of the fabric.
02. If the top fabric is light-colored and the base fabric is dark, the color of the base fabric will have a greater impact on the color of the base fabric.
2. Wash off/foam
After the fabric is compounded, due to poor bonding fastness, partial detachment or blistering occurs during washing.
3. Fold and wrinkle
When the non-elastic thin fabric is used as the top fabric and the base fabric is thicker, it is easy to fold and wrinkle.
4. Washed bark wrinkles
When a composite fabric with a shrinkage difference of more than 3 points between the top fabric and the base fabric and a large difference in fabric thickness is washed, a bark wrinkle effect will occur on the thin fabric surface due to the difference in shrinkage.
5. Adhesive penetration
The woven fabric is light-colored and thin. After the glue is matured, glue spots can be seen on the cloth surface.
6. Glue overflow
Fabrics with sparse texture and hard feel are prone to glue seeping out of the fabric surface.
7. Colored yarns in light-colored fabrics stand out due to compounding
For white fabrics, especially white woolen fabrics, fabric defects such as colored yarns in the white fabric are particularly prominent due to the background fabric after lamination.
8. Composite entrained foreign matter
During the PU composite production process, it is easy for impurities (such as hair, fiber scraps, etc.) to fly into the composite glue, and the foreign matter entrained when composite light-colored fabrics will appear on the cloth surface.
9. Curling
Elastic fabric and non-elastic fabric are bonded together and the elastic fabric is thicker than the non-elastic fabric. During the composite production process, if the surface tension of the fabric is not well controlled, it will easily curl. 9pCT18r
