在日常穿衣的过程中,最麻烦的事情就是早上急着要出门的时候收拾衣服。我经常有这种烦恼。我不知道你会不会。熨烫太迟了是很费时的。服装面料的褶皱直接影响服装的美观和穿着效果。那么,衣服为什么会起皱,日常生活中又该如何应对防皱呢?那么到底是什么导致织物起皱呢?起皱:织物在穿着、洗涤护理过程中,由于摩擦、挤压、扭转、扭曲等外力作用而产生的折痕或褶皱现象称为起皱。1.微观视角构成织物的纤维在外力作用下发生变形。 After the external force is removed, the deformation cannot disappear, cannot be restored to its original state, or can only be partially restored. 2. Macro perspective Wrinkle formation can be divided into two stages: crease generation and crease recovery after external force removal. 1) Crease generation: Under the action of external force, the fabric is bent and deformed. Since the external force is far greater than the resistance of the fabric due to bending, the fabric is forced to bend and deform, that is, beyond the bending elastic deformation range of the fabric, yielding deformation. 2) Crease recovery After the external force is removed, the crease bending of the fabric begins to recover under the elastic recovery force generated by the internal stress, that is, the angle of crease recovery starts to increase. With the extension of time, the crease recovery angle increases, and its change is similar to the material creep law. In this process, in addition to the elastic recovery force of the fabric, it is also affected by the friction resistance, which is generated by the relative slippage between the yarns and between the fibers of the yarn, and its direction is opposite to the elastic recovery force. When the elastic recovery force and friction resistance of the fabric are balanced, the fabric reaches the maximum recovery effect. At this time, the fabric folding angle is the crease recovery angle of the fabric. Crease resistance of fabrics: The ability of fabric to resist wrinkling and deformation is called wrinkle resistance, that is, the fabric can be folded and pressurized under specified conditions. After the load is removed, the crease of the fabric can return to the original state to a certain extent, which is also called the crease recovery of the fabric. It can be seen from the causes of fabric wrinkling that to overcome the shortcomings of fabric wrinkling, it is necessary to reduce the opportunity for fiber to generate relative displacement between macromolecules under external force, or prevent the formation of hydrogen bonds at new positions when macromolecules have relative displacement, so that macromolecules can quickly return to their original positions after the removal of external fo...
