Shirt Washing Process for Central Laundry Plants

Shirts are the most common clothes in both business and leisure scenarios. A smooth, crisp, and clean shirt can directly improve the overall image and temperament of a person. Cotton shirts easily have wrinkles, deformation, hard collars, dull color, and other problems after being washed, dehydrated, and dried at home. It is difficult to restore the ideal shape and flatness. As a result, more and more customers choose to handle shirts at professional laundry shops or a central laundry plant for standardized laundry. The central laundry plants use a systematic process, professional equipment, and refined operation to control the cleanliness, flatness, and shape retention of shirts. This greatly improves the service life and wearing experience of clothes.

Sorting and Pre-treatment

The first step of professional shirt laundry is strict sorting and pre-treatment. This is an important link for avoiding laundry accidents and ensuring quality. Laundry staff should check the clothes one by one.

● Cuffs, plackets, and collars

loose buttons, missing buttons, or loose threads?

heavy soil like sweat, oil, and stains on High-contact areas?

● Special decorations

Rhinestones, embroidery, prints, or sequins that may need extra protection or hand care?

After checking, the shirts should be sorted according to color to prevent color bleeding and transfer during washing. This lays a solid foundation for safe, consistent cleaning.

Though light shirts have similar components to dark shirts, the differences in the washing logic and program settings are obvious. Light-colored shirts focus on cleanliness, stain removal, and gentle shape protection. Its process is simple and efficient. Dark-colored shirts focus on color protection, preventing color fading, preventing whitening, and preventing mottling. The process is more meticulous, and the steps are more complete. In addition, since shirts are usually worn close to the body, the collars and cuffs are typically pre-treated before being machine-washed in batches.

Standard Washing Process for Light-colored Shirts

Light-colored shirts include white, light blue, light pink, and light gray. Key requirements are thorough cleaning, no yellowing, no stiffness, and a smooth finish. As a result, it is suggested to use a gentle, short cycle with low-speed extraction.

Standard Washing Process for Dark-colored Shirts
