Common Problems with Composite Fabrics and Solutions

  • Solutions to problems of composite fabrics: Selection of surface and base fabrics Best: Consistent width, consistent shrinkage, and consistent thickness 1. If the difference in shrinkage is greater than 3 points, fabrics with smaller shrinkage should be selected thicker than fabrics with larger shrinkage (specific sample to be determined). 2. The fabric before laminating should not undergo hydrophobic softening treatment, especially fluorine based waterproof treatment. 3. Try to avoid choosing white fabrics, especially white woolen fabrics, for laminating purposes 4. High value fabrics should have a narrower width than low value fabrics before entering Laminating Machine, and the difference in width should not exceed 10CM, otherwise there will be significant waste. 5. Try not to use fabrics with production risks for laminating.​
    Solutions to composite fabrics problems: Laminating process 1. Ready to wear clothing requires dry cleaning of fabrics and the use hot melt Pur Laminating Machine. 2. When laminating, the fabric should be aligned with the strands to avoid weft skewing, twisting of straight threads, etc 3. Adequate mid-term maintenance treatment is necessary, otherwise the peel strength will be poor. 4. Laminating processing may seem simple, but it is closely related to the experience, technology, and operational proficiency of the laminating factory. 5. The composite fabric cannot be recombined, and even if peeled off, it will affect the yarn of the fabric, making it harder to feel and easily punctured by needles. 6. Non elastic high-density shuttle fabric needs to be laminated with film, otherwise the fastness is poor​

    What are common problems of composite fabrics?

    Common problems with composite fabrics: Fabric color: 1. The processes of gluing, hot pressing, drying, etc. during the laminating process have an impact on the color of the surface material. 2. The surface fabric is light colored, and the base fabric is dark colored. The color of the base fabric will have a significant impact on the color of the surface fabric when combined with the color of the base fabric by laminating machine. Water washing detachment/foaming: Due to poor adhesion after fabric lamination, local detachment or foaming may occur during washing. Folding and wrinkling: When non elastic thin fabric is used as the top fabric and the bottom fabric is knitted thicker, it is easy to fold and wrinkle during laminating process. Washed bark wrinkles: Composite fabrics with a shrinkage difference of more than 3 points between the top and bottom fabrics and a significant difference in fabric thickness will produce bark wrinkles on the thin fabric surface due to the shrinkage difference when washed. Glue-through: The woven fabric is light colored and thin, and the adhesive dots can be seen on the fabric surface after aging. Squeeze-out: Fabric with sparse organization and a slightly hard texture is prone to glue seeping out of the fabric surface during laminating. Light colored fabric and yarn are highlighted due to their composite effect: White fabrics, especially white woolen fabrics, have prominent fabric defects such as colored yarns due to the contrast of the base fabric after laminating. Composite inclusion of foreign matter: Impurities (such as hair, fiber shavings, etc.) are prone to fly into the composite adhesive during the production process of PU laminating, and foreign objects carried during the laminating of light colored fabrics will appear on the fabric surface. Edge curl: Elastic fabric and non elastic fabric are bonded/laminated together, and the thickness of elastic fabric is thicker than that of non elastic fabric. If the tension control of the fabric surface is not very good during the laminating production process, it is easy to roll the edges.
