After drying, garments may form excessive wrinkles. This not only increases ironing time but also damages fabric fibers, which shortens their service life. Commercial dryers help reduce garment wrinkles at the source. But a single operation is ineffective. Wrinkles should be processed from four key stages: pre-drying treatment, precise parameter control, immediate post-drying setting, and daily equipment maintenance. Therefore, drying time can be shortened. Ironing difficulties after drying will be reduced.
Pre-Drying Treatment
Before drying, many wrinkles have already developed on garments. Proper pre-loading treatment can reduce about 70% of stubborn wrinkles. Pay attention to the following three points before putting garments into the machine.
- Standardize loading capacity
The loading ratio should be controlled within 60% of drum capacity. Sufficient space allows garments to tumble freely. This avoids fabric stacking and compression. They may form permanent wrinkles that cannot be smoothed out.
The load-to-volume ratio of a Kingstar commercial dryer is 1:20. Compared with common dryers, it has a large drum volume. Under the same conditions, garments have more tumbling space without tangling and compression. This reduces wrinkle risks at the loading stage. Strictly prohibit full-load or overloaded drying. Overloading directly blocks hot air channels. This may bring uneven drying and wrinkles.
- Shake out & smooth out garments
Shake out garments before loading. At the same time, smooth out cuffs, collars, and hemlines to prevent clumping and tangling. For easy-to-wrinkle garments (such as shirts and uniforms), place 2-3 wool dryer balls. During the drying process, balls constantly hit fabrics to break up tangled knots. Hot air circulation can also be improved. This further reduces localized stiffness and wrinkles.
- Sort fabrics & unify drying time
Thick garments (workwear, light shirts, and uniforms) should be sorted. They often absorb more moisture. Meanwhile, they need a longer drying period. Thin fabrics dry more rapidly. Mixed-load drying may cause over-drying of thin garments. Thick clothes may still remain damp. Besides, fabric fibers lose elasticity due to over-drying. Wrinkles become permanently set. After stacking and cooling, the damp fabrics may develop new wrinkles. Separate drying can match the corresponding drying time to ensure the dryness levels.
Precise Parameter Control
Fiber condition is directly affected by drying temperature, drum operation mode, and hot and cold air circulation. Improper parameter setting is a main cause of stubborn wrinkles. Parameters should be adjusted according to fabric features. The drying process can be optimized with Kingstar’s dedicated hot and cold air circulation as well as forward and reverse rotation functions.
- Temperature control by fabrics
Cotton and linen fabrics can withstand higher temperatures. The drying temperature is between 60℃ and 75℃. Do not choose high-temperature rapid drying above 80℃. Otherwise, surface fibers may quickly dehydrate and shrink. Internal fibers still contain moisture. This can easily develop deep-set wrinkles.
Polyester-cotton blends, synthetic workwear, and table linens have lower heat resistance. The temperature should be set between 50℃ and 60℃. High temperatures easily cause synthetic fabrics to shrink and become stiff, which cannot be restored.
Wool and silk are high-end delicate fabrics. The temperature should be controlled within 50℃. Switch to gentle low-speed mode, which reduces mechanical stress. It also avoids fabric deformation and wrinkles.
- Remove garments at 90% dryness
Completely dried fabrics become stiff and brittle. Set wrinkles cannot be removed. A little moisture makes fabrics stay flexible. Slight wrinkles can be smoothed out with residual heat. This greatly reduces ironing workload.
- Spin speed optimization & forward and reverse rotation function
Moderately increase spin speed. This helps improve contact between fabrics and hot air. This accelerates even moisture evaporation.
Kingstar commercial dryer is equipped with a smart forward and reverse drying program. The drum switches the rotation direction at regular intervals. This thoroughly addresses garment tangling and knotting caused by continuous one-way tumbling. At the same time, the machine has a unique hot and cold air circulation system. When the inner temperature reaches the maximum value, it automatically cuts off the hot air. Cold air enters to neutralize the high inner temperature. Fibers have time to restore their flexibility. When the temperature drops to the minimum value, it automatically restarts the hot air. Hot and cold air cycles protect fabrics. This avoids fiber hardening caused by excessive heat. Wrinkles can be reduced during drying processes.
- Drying time control
When fabrics reach 90% dryness, stop the machine and remove garments. Prolonged high-temperature drying results in moisture backflow. This forms a large area of wrinkles, which greatly increases later ironing difficulties.
Immediate Post-Drying Setting
After drying, the key is to remove slight wrinkles and prevent secondary wrinkles. Residual fabric heat is essential for setting. Delayed finishing may form permanent wrinkles.
- Heat-assisted setting
After drying, take out garments immediately. Use residual heat to iron the fabrics. Slight wrinkles can be removed by hot steam and mechanical stretching.
- Hang or lay flat for storage
Hang up clothes immediately after finishing. Large items (bed sheets and duvet covers) should be laid flat for storage. Do not stack them on laundry carts or baskets. After cooling, fabric fibers become set. Multiple layers stacked under pressure may form new wrinkles. The previous wrinkle reduction becomes ineffective.
Daily Equipment Maintenance
Poor equipment condition affects hot air circulation, which causes uneven drying and localized wrinkles. So daily maintenance and assisted functions cannot be overlooked.
- Choose cool-down cycle
After drying, extend the cool-down cycle for 3-5 minutes. The constant cold air in the drum further releases residual heat inside fibers. Fabrics completely recover their flexibility. This not only reduces wrinkles but also improves garment hand feel. It further prevents odors and hard wrinkles caused by residual heat.
- Regularly clean equipment
After each operation, clean lint from the filter. Deeply clean the inner drum surface every week. Residual lint may block hot air ducts. Unstable airflow easily causes localized over-drying and dampness to generate wrinkles. Keep the inner drum surface smooth and clean without stains and lint buildup. So even airflow can circulate around garments to deliver stable drying performance. In the long run, wrinkles are less likely to be generated.
Conclusion
The wrinkle reduction solution covers the entire drying process, from pre-loading treatment and smart parameter control to immediate post-drying setting and daily equipment maintenance. Meanwhile, Kingstar commercial dryers feature professional functions, such as forward and reverse rotation as well as hot and cold air circulation. They improve both drying efficiency and linen quality. These machines effectively reduce wrinkles in various fabrics and ironing workload. Some garments can be worn after drying.
Q&A
Q1: How many automatic drying programs does a Kingstar commercial dryer have?
A1: 20.
Q2: What is the hot and cold air circulation of a Kingstar commercial dryer?
A2: When the temperature reaches the maximum value, hot air is replaced with natural air. When the temperature reaches the minimum value, hot air re-enters. This improves energy efficiency as well as protects garments.
Q3: How many programs does a Kingstar commercial washer have?
A3: 30.
