Are the washing methods for casual pants all uniform? No, the washing methods for casual pants made of different fabrics and with different color fastness are not the same. The color fading pattern is closely related to factors such as fabric material, dyeing process, and color depth. Mastering the pattern and combining it with the correct washing method can effectively reduce the color fading problem.
Color Fading Types
The color fading characteristics of different casual pants are different.
- The striped and plaid casual pants basically do not fade when washed, but they will fade after long-term exposure to sunlight. The fading is due to incorrect drying methods rather than the washing process.
- Jeans are rather special. Color fading during regular washing is a normal phenomenon. It generally will not contaminate other clothes. The indigo model has a unique design and craftsmanship feature that slightly fades and creates a natural aged texture.
- The color fading of all-cotton knitted sportswear pants is closely related to the depth of the color. Light-colored ones have stable colors and basically do not fade after washing, while dark-colored ones, such as deep purple, deep blue, and pure black, have a significantly higher probability of color fading. Knitted cotton-polyester casual pants, with their composite material properties and suitable dyeing processes, mostly have good color fastness and basically no color fading problem.
Light-colored Cotton Pants
Among the color fading issues of various casual pants, what troubles consumers the most is not the common dark-colored ones, but the color fading and color rubbing problems of some light-colored all-cotton casual pants. The color fading performance of such items is directly related to the product grade and dyeing process. The color fading probability and precautions of light-colored all-cotton casual pants of different grades vary significantly and can mainly be divided into three grades.
- High grade
High-end light-colored 100% cotton casual pants are made with strict fabric and dyeing requirements. They use fine, dense cotton and high-quality vat dyes, so they stay colorfast and rarely fade in daily washing.
Some premium versions also have resin anti-shrink treatment, which keeps them from fading and shrinking, but the fabric can feel a little stiffer and less resistant to rubbing. They may get scuffed or pill easily if rubbed against hard items, so for industrial washing, just turn them inside out or use a laundry bag.
- Middle grade
Mid-range light-colored all-cotton casual pants, although the dyeing process is not as strict as that of high-end models, can still ensure good color stability. They are mainly dyed with reactive dyes, and high-quality models may also use reductive dyes. They are less likely to fade during daily washing. However, for some styles of this type of trousers, the rubbing fastness is relatively low. When washing, it is strictly forbidden to scrub vigorously with a laundry brush. The dye may fall off in some areas, resulting in uneven color and color differences.
- Middle and low grade
Mid-to-low-end light-colored all-cotton casual pants are a high-risk category for color fading and color rubbing problems. The core reasons are the non-standard dyeing process, the disorderly selection of dyes, often mixing direct, sulfur, reactive, and other dyes, and the rough fixation treatment, which makes the dyes unable to closely combine with the cotton fibers, resulting in frequent color fading issues. This type of trousers, the dark-colored ones, tend to lose color severely when washed, which can easily cause color bleeding among other clothes. The light-colored ones do not lose color significantly when washed, but they have extremely poor abrasion resistance and should not be scrubbed either. The correct washing method should be adopted to reduce color loss.
Correct Washing Methods
Mastering the correct washing methods can solve many problems from the source and extend the trousers’ service life.
- Basic principle of washing
– It is recommended that all casual pants be turned over before washing to reduce direct friction between the front of the fabric and the inner wall of the washing machine or other clothes, avoiding color rubbing and fabric damage.
– For the first wash of dark casual pants, they can be soaked in light salt water or white vinegar water for 10 to 15 minutes.
– Kingstar washing machine SHS-2025
Washing process water temperature can be set according to the following parameters:
Water temperature: less than 30℃
Speed: 30rpm
Main wash time: 15-20minutes
Chemicals: Avoid using strong corrosive detergents and use neutral laundry detergent.
Targeted Washing
- Striped and plaid casual pants
The key is to prevent exposure to direct sunlight rather than color fading after washing. Don’t dry them in direct sunlight.
The drying process is carried out using the Kingstar intelligent dryer, with the drying temperature set at less than 60℃. The drying degree can be controlled through the dryness and humidity control system of the Kingstar dryer to avoid over-drying and fading.
- Jeans
Jeans can be washed separately in cold water. When washing, choose a gentle washing mode. After washing, let them air dry naturally to retain their aged style. Indigo jeans must not be washed together with light-colored clothes.
- Light-colored items can be machine-washed normally. For dark-colored ones, it is recommended to wash them gently in cold water separately. Avoid washing them together with other light-colored clothes to prevent color bleeding. Polyester-cotton casual pants have strong color stability and can be machine-washed regularly without special color-fixing treatment. Just avoid high-temperature drying.
- Air dry and store
All casual pants are recommended to be air-dried after washing and stored in a well-ventilated and cool place.
Conclusion
Laundries need to understand the color fading patterns of different casual pants and match them with the correct washing, drying, and storage methods. Only in this way can they carry out targeted batch washing, improve efficiency, and reduce problems caused by washing.
