What is the function of the shaping process for ultrafine fiber beach towels
The shaping of ultrafine fiber beach towels is generally carried out in the latter half of the dyeing and finishing process, using a stretching and shaping machine to heat treat the fabric under set temperature, tension, and vehicle speed conditions. This is a key process for controlling the appearance and dimensional properties of the fabric, and its main functions are as follows:
1. Stabilize product size and reduce water washing shrinkage changes
During the weaving and dyeing process of ultrafine fiber fabrics, internal fiber stress accumulates, and they are prone to shrinkage when exposed to water and heat. Shaping is achieved through high-temperature relaxation or moderate stretching to release residual stress inside the fabric, reduce dimensional deformation after subsequent washing and seawater immersion, control the rate of washing dimensional changes, and ensure that the length and width specifications of beach towels remain stable after repeated use.
2. Adjust the width of the fabric door and unify the width
The dyed fabric is prone to uneven width of the door and uneven width on both sides and in the middle. The shaping process can pull the fabric to the agreed width in the contract, keeping the width of the same batch of products consistent, facilitating subsequent cutting, edging, printing and other processing, reducing the difference in cutting size.
3. Smooth the fabric surface and improve the appearance flatness
The defects such as wrinkles, weft skewers, and curved edges that occur during the weaving and dyeing stages can be corrected during the shaping process by adjusting the weft angle to reduce weft skewers and make the fabric surface flat, ensuring that the subsequent printed patterns will not be distorted or misaligned, and improving the visual effect of the finished product.
4. Control the texture and fluffiness of the fabric
By adjusting the setting temperature, vehicle speed, and overfeeding amount, the curling state of the fibers can be changed. Reasonable shaping parameters can maintain the soft and fluffy texture of ultrafine fiber fabrics; Excessive temperature or prolonged residence time can cause fibers to harden and affect the tactile feel during use.
5. Consolidate and organize the functional effects after consolidation
If the fabric is treated with functional additives such as water absorption, antibacterial, and cold sensation, the heat treatment for shaping can better adhere the additives to the fiber surface, improve functional durability, and reduce the rapid detachment of additives during washing.
6. Improve fabric flatness and optimize printing compatibility
A flat and stable fabric surface is less likely to bulge or shift during digital printing or heat transfer printing, which helps to achieve uniform coloring of the pattern and reduce the proportion of defective products such as blurry printing and ghosting.
