Why do the towels in laundry plants more easily have damage than other linens? Despite washing, dewatering, and drying, are there any reasons for damage?
Liner Quality of the Laundry Equipment
● Industrial Washing Machine
The inner drum of an industrial washing machine is made of stainless steel through welding. The surrounding plate is punched with small holes, and during the manufacturing process, deburring treatment must be done on the back of these holes. However, if the quality of this process is substandard and there is a large number of burrs remaining or individual burrs left untreated, it will cause fabric snags.
Another possibility is that the damage is caused by gaps at the joints between the V-shaped ribs of the inner drum and the surrounding plate. During the washing process, the inner drum will deform due to thermal expansion and contraction. Some small gaps in the inner drum often widen after heating. If the gaps are uneven, when a towel is caught in a wider gap and forced through a narrower gap as the inner drum rotates, it is likely to be torn.
The inner drums of tunnel washers are produced through welding.
Some tunnel washers adopt gas metal arc welding (GMAW) during the welding process, which causes weld spatter. This easily results in an uneven inner drum surface that is difficult to clean. Argon arc welding can avoid the above problems.
Also, insufficient welding strength may lead to cracks in some areas. This can also cause towel damage because towels have a looped structure and are more easily snagged.
Some tunnel washers use single-sided welding, so it is difficult to guarantee a good welding strength. Therefore, people need to inspect these detailed aspects when selecting and purchasing laundry equipment.
The Usage of Detergent
● Incomplete Rinsing
If the rinsing during the laundry process is not enough, although the alkalinity will not harm the pure cotton fibers, the alkaline detergent remains in the towel fibers. This causes the towel to turn gray and hard after drying, and its softness will decrease. It will accelerate the damage to the towel during use and transportation.
● Residues of Chlorine Bleach
Chlorine bleach must be added strictly according to the ratio. Excessive dosage, improper temperature control, or inadequate rinsing all lead to residues of chlorine. This will cause towels to shed fibers and eventually break down.
● Dosage of Neutralizer
The neutralizer is added lastly during the washing process. After being added, it can neutralize the small amount of alkaline chemicals and chlorine bleach remaining in the fabric from the previous washing procedures, and after rinsing. It can dissolve some metal ions in the water. Correct dosage can make the pH value of the linen between 5.5 and 6.5, which is basically consistent with human skin’s pH value. It is safe for humans, and the textiles are still within their normal service life.
However, many laundry plants excessively pursue softness and add a large amount of neutralizer improperly. The residues of acid detergents will reduce the fastness of the towels.
If laundry plants use industrial washing machines for washing, they should load the machines according to the standard loading volume as much as possible. Choosing washer extractors that can edit washing programs can achieve standardized washing as much as possible. If a tunnel washer is used, people only need to set the programs to achieve standardized washing.
Conclusion
All the above are the main reasons for towel damage. If people pay attention to all these issues when purchasing laundry equipment or do daily laundry, the service life of towels can be extended as much as possible.
