Viscose, a semi-synthetic fabric made from wood pulp, has become increasingly popular in recent years due to its soft, breathable, and lightweight properties. However, one of the major drawbacks of viscose is its tendency to shrink, which can be frustrating for consumers and manufacturers alike. In this article, we will delve into the world of viscose care and explore the various methods to prevent shrinkage, ensuring that your viscose fabrics remain in pristine condition.
Understanding Viscose Fabric
Before we dive into the prevention methods, it is essential to understand the characteristics of viscose fabric. Viscose is made from wood pulp, which is treated with chemicals and then woven into a fabric. This process makes viscose prone to shrinkage, as the fibers can contract and relax, causing the fabric to lose its shape. The degree of shrinkage can vary depending on the type of viscose, the weaving process, and the finishing treatments applied to the fabric. Generally, viscose fabrics can shrink by up to 10% in length and 5% in width, which can significantly affect the overall fit and appearance of a garment.
