1. Identification First
In recent years, sweatshirts and knitted outerwear have become increasingly popular. Sweatshirts are not only warm to wear in winter but also lightweight and casual in summer. They can be made from many different materials and come in various styles.
Knitted fabrics have a distinctive feature: they have a looped structure. Once identified as knitted garments, they should be carefully maintained according to the care label instructions.
Due to different fiber types, sweatshirts and knitted fabrics may encounter various issues, including stretching, shrinking, and pilling during wear or cleaning. Therefore, it is important to thoroughly check the garment before washing and determine whether it may cause damage. This is very important because of liability concerns.
2. Washing Treatment of Foam Cups and Shoulder Pads
Foam cups can exist as polyurethane foam under non-textile cotton layers or fabric outer layers, and may also be cotton thread or polyester. The covering of shoulder pads is usually made of synthetic materials or the same material as the garment.
Foam cups are typically used to enhance the stability and firmness of women's clothing, especially wedding dresses and other formal wear. Foam cups can be sewn onto the garment, placed in pockets, or adhered to appropriate adhesive materials.
When dealing with garments containing foam cups or shoulder pads, the following points should be noted during washing.
① The foam material of shoulder pads or foam cups usually fades when exposed to dry cleaning solvents. Stains cause the foam material to gradually decompose and rot. This damage is usually cumulative and may only appear after a long time.
② When foam decomposes, it produces powdery or gritty residues that may affect the garment.
③ Some foam cup materials are soluble in certain solvents; when immersed in dry cleaning solvents, the material softens or even decomposes.
④ The dissolved material can also seep through the garment's surface, causing fading and hardening. This damage is cumulative and worsens with more cleaning cycles.
⑤ For lighter or transparent fabrics, damage is usually more obvious at the shoulder pad seams. During cleaning, shoulder pads may retain a large amount of solvent, and as the weight increases, the shoulder pad may separate from the fabric's outer layer.
⑥ Distortion and displacement of shoulder pads. This damage is directly related to the structure. If the shoulder pads are poorly sewn, they are prone to displacement, which exacerbates deformation.
