Is your laundry also facing such a dilemma: After the white linen goes through the washing process, its whiteness index seems to be qualified, but it always feels that it lacks the necessary brightness and transparency?
Three Reasons that Affect the Transparency and Luster of Linen
❑ Substandard Cleanliness
Whiteness doesn’t equal cleanliness. If there are stains, grease, or mineral deposits that have not been thoroughly removed from the surface or deep in the fibers of the linen, even if chemicals with whitening effects are used, they can only cover up part of the yellow tone and cannot bring about a truly clear and lustrous appearance. This is often due to the insufficient active ingredients in the detergent formula or inadequate actual addition of chemicals.
❑ The Improper Setting
● Improper Settings of Process Parameters
The laundry isn’t just the simple “wash and rinse”. Improper process parameters directly have an impact on the final effect. Overloading of the machine results in insufficient tumbling of the linen and uneven distribution of the washing liquid, and this affects the decontamination and rinsing effects.
● Unbalanced Input of Detergents
There are several reasons that can lead to the absorption of residue onto the fibers and make the material not transparent: strong alkalinity (excessive dosage of caustic soda), insufficient washing time, substandard neutralization, insufficient number of rinses, and insufficient water.
● Unreasonable temperature and time
High temperature is not always beneficial, especially for certain stains or chemical detergents. Excessively short washing time or rinsing time cannot give people satisfactory cleanliness as well.
● Unqualified detergents
Cheap sometimes means a high price. Some cheap detergents have a low content of active ingredients and are filled with a large amount of ineffective substances. These substances not only do no favor to the cleanliness but also increase the burden of washing.
❑ Incomplete rinse
When the rinse is not thorough, the detergents may easily remain on the linens and form a dull layer. In the short term, it affects the luster. In the long term, it accelerates the graying, yellowing, and hardening of the linen.
Solutions
How to wash clean and shiny linen? Once the crux of the problem is identified, the solution will be more targeted.
❑ Optimize and Adhere to the Washing Process
● Users of Tunnel Washers
Because the laundry process and the addition of detergents of the tunnel washers are all controlled by the system, which belongs to a standardized laundry. Laundry plants should note that the loading volume should be between the zone required by the manufacturers.
● Users of Industrial Washing Machines
Strictly follow the instructions of the equipment and the scientific processes. Never arbitrarily delete steps, compress time, or overload the operation. Reasonably plan the washing cycle to ensure enough time for wash, rinse, and neutralization. Ensure the loading volume is in the range of the loading capacity to let the linen thoroughly stretch and roll. In the future, we may write an article about the program parameter settings for washing linen in industrial washing machines.
❑ High-quality and Standardized Detergents
When choosing detergents, you should comprehensively consider:
● Appearance
The powder should have uniform particles and consistent color (if colored materials are used, they need to be mixed evenly). Liquids should be uniform and stable without stratification, sedimentation, or pungent odor. The quality of each batch should be stable.
● Active Ingredient Content
Proactively inquire about the concentration of active ingredients in the supplier’s products. High-concentration products mean fewer ineffective fillers. Although the unit price may be slightly higher, the actual washing cost per piece is often lower (less usage, better effect, and lighter burden).
● Rational Compare the Prices
When the content of active ingredients is similar, compare the prices and choose the one with the best overall cost performance.
● After-sales service
Choose a professional supplier that responds in time. Avoid excessive service: frequent after-sales service means the quality of the product itself is not stable. Relying on the after-sales service to fix the flaws is a burden for both parties. Choosing suppliers with stable quality and moderate after-sales service is more reliable.
