Why does the fiber strength of hotel linen gradually decrease?
Hotel linen needs to be strictly washed after each guest’s use, resulting in a high washing frequency. The stains attached to the linen under certain washing materials, water quality, and process conditions are common problems. Today, Ulencn.com will mainly discuss the reasons for the significant decrease in fiber strength of hotel linen.
Normal washing of hotel linen can lead to varying degrees of fiber strength reduction and decreased fabric cohesion, but this decrease is usually slow. If the decline is significant, it indicates potential issues in the washing process.
- Excessive concentration of bleach, especially if too much chlorine bleach is used, can severely damage fabric cohesion.
- If the pH value of the chlorine bleach is too low during washing, it can cause the bleach to release too quickly, affecting fiber strength.
- Washing at excessively high temperatures during bleaching can lead to over-bleaching and damage to the fibers.
- Long-term washing in high-temperature and high-alkaline conditions, although pure cotton fabric itself is relatively alkali and heat-resistant, can still lead to a rapid decrease in fiber strength over time.
- If the water level during washing is too low, it can lead to a high concentration of detergent, causing excessive mechanical stress on the fabric.
- Failure to rotate the drum during bleaching can result in locally high bleach concentration for a period, damaging plant fibers.
- Pure cotton fabric is very sensitive to acids, and adding acidic substances to the detergent can cause significant damage to the fiber strength of pure cotton fabrics.
