Stain-resistant Finish

Definition and Overview

Stain-resistant finish is a general term for finishes that improve a textile's resistance to stains from sebum, oil, food and drink, dust, and other dirt, or make such stains easier to remove in washing. There are types that make it harder for dirt to adhere to the surface and types that make dirt easier to release from the fibers, and some finishes provide both performances.

SR finish generally refers to soil-release finish and means a function that makes dirt easier to wash away. On the other hand, oil-repellent finish mainly refers to a function that makes oily stains easier to repel, but the name and performance range vary by textile, so it is necessary to check the specifications.

Characteristics and Effect on Appearance

Depending on the finishing method, fiber type, and weave or knit structure, the types of stains that the finish works well against and the durability will differ. Since some finishes focus on resistance to oily stains, while others make mud and similar dirt easier to remove in washing, choose one based on the stains you want to prevent.

Depending on the finish, the textile's absorbency, breathability, hand, luster, and firmness may change. In some cases the appearance does not change much, but for whitening on dark colors, surface texture, and compatibility with prints and fusible interlining, check an actual textile sample.

Main Applications

It is used for shirts, blouses, pants, skirts, dresses, uniforms, and workwear where stains from food, drinks, or sebum are likely to be a problem. For bags and interior products, it may be adopted as a measure against hand marks and everyday dirt.

It is not a finish limited to any season, but it tends to be easy to specify the required performance for spring and summer clothing that is prone to sweat and sebum, outerwear worn in rain or outdoors, and work clothing that gets dirty easily. Depending on the material and application, it may also be combined with moisture-wicking quick-dry or water-repellent finishes.

• Shirts and blouses
• Pants, skirts, and dresses
• Uniforms and workwear
• Outerwear, bags, and interior products

Selection and Handling Notes

When selecting, check the type of stain to be targeted, washing method, wearing frequency, and required durability. Stain-resistant finish does not completely prevent stains, and depending on the type of finish, performance may decline with repeated washing, friction, or dry cleaning.

As for shrinkage, check the effect of the base fabric's fiber composition, structure, and finish rather than the stain-resistant finish itself. Before mass production, it is important to evaluate shrinkage rate, appearance changes, stain removal, and color fading under the intended washing conditions, and to ensure consistency with the care label instructions.

In sewing, take care that dirt such as chalk marks and adhesive does not remain on the finished surface. For textiles with a slippery surface due to the finish, misalignment during cutting or sewing may occur. When using fusible interlining, prints, or embroidery together, check adhesion and appearance in advance.

Differences from Similar Terms

Water-repellent finish is a finish that repels water droplets and makes the surface less likely to get wet. It may be used together with stain-resistant finish, but water-repellent finish, which focuses on performance against water, and stain-resistant finish, which targets prevention of adhesion and removability of oil, sebum, and solid dirt, have different purposes.

Waterproof and breathable is a performance that suppresses water penetration from the outside while allowing water vapor inside the clothing to escape. Stain-resistant finish does not mean waterproofness. Also, moisture-wicking quick-dry is a function that absorbs and disperses sweat and other moisture to help it dry more easily, and it is a different performance from stain adhesion or washability.
