Kommer vårens höstskolväst att deformeras om de tvättas för mycket?

The deformation resistance of the spring autumn school vest is directly related to its fabric structure and seam process. This type of clothing usually uses blended fabrics to balance breathability and stiffness, but the difference in thermal shrinkage of different fibers will gradually appear during wet and hot washing. The coil morphology stability of knitted fabrics is restricted by the twist and resilience of the yarn. Repeated mechanical force may cause longitudinal distortion or lateral shrinkage.

The sewing thread density and adhesive treatment at the seams of the spring autumn school vest determine the stress dispersion efficiency, and high-frequency friction can easily induce stitch slippage. The shrinkage matching of the lining and the fabric affects the overall flatness. If the interface bonding force is insufficient, interlayer wrinkles may occur.

The swelling effect of chemical detergents on the coated fabric of the spring autumn school vest cannot be ignored, and the microscopic cracks of the surface waterproof film accelerate in an alkaline environment. The centrifugal force generated by drum drying imposes forced deformation on the three-dimensional cutting parts, while the gravity drape of natural hanging may change the original pattern curvature. The photo-oxidative degradation products of some cheap dyes will weaken the intermolecular forces of fibers and indirectly reduce the stability of fabric structure.

In industrial practice, accelerated aging tests are used to simulate the effects of long-term washing, but the composite loads in actual wear are difficult to fully reproduce. Whether a spring autumn school vest will deform after excessive washing is related to many factors.
