Swimsuit Fabric Shrinkage Pretreatment and Countermeasures in Actual Production

Time:

Apr 24,2024

Usually, swimsuit fabrics are made of synthetic fibers such as spandex and polyester. These material fabrics have good elasticity and chlorine resistance. Although this polyester cloth material has relatively low shrinkage, some shrinkage may still occur during production or first laundering.

In order to ensure swimming suit size stability and wearing comfort, swimsuit manufacturers often take pre-treatment measures to reduce size changes. This preprocessing helps:

Reduced Size Variation: By addressing shrinkage early, pre-treatment minimizes size discrepancies during use and laundering.

Improved Durability: Pre-treatment enhances fabric resilience against water and chlorine exposure, reducing damage from shrinkage.

Enhanced Consumer Satisfaction: Stable sizes lead to happier customers, fewer returns, and better overall product experience.

Maintained Design Shape: Pre-treatment preserves the intended design shape, preventing deformation during washing. Preprocessing methods may include:

 

Steam pretreatment: Use steam to treat fabrics to simulate shrinkage in hot and humid environments.

Mechanical pretreatment: Pre-shrink the fabric in a tension-free state by mechanically squeezing and stretching it.

Washing pre-treatment: soaking fabric in water and drying to simulate shrinkage during washing.

Pre-processing of swimsuit fabric is a critical step in the production process and helps ensure the quality of the final product.

However, the exact treatment will vary depending on the materials used and the design requirements of the swimsuit.

Some simple styles, such as the micro bikinis that has become popular in recent years, are basically designed with straps, and the size can be adjusted according to the straps. The shrinkage rate will not have a great impact on this type of product.

For some styles, such as the plus size swimsuit for women Short sleeve rash Guard designed for plus-size women, even after the pre-treated fabric is processed into a swimsuit, there is still a possibility that the size will exceed the tolerance due to shrinkage. In the actual processing process, we recommend that customers choose full size production when making pre-production samples based on the order situation. Although this will cost more, it is very important to ensure that the sizing is accurate, especially for plus size swimsuits. For example, if the length of a swimsuit is 100 cm and the shrinkage rate is 4%, then the shrunk length will be 96 cm, which may be outside the tolerance range. Therefore, there is a certain risk if you only make small-size pre-production samples as a reference.
