Why do towels turn yellow after a long time?

Towels are often exposed to grease and perspiration when used.

Dirt and perspiration can restore the color of the natural pigments in cotton fibers.

Frequent washing and sun exposure will speed up this process, so the towel will turn yellow after a long time.

Towels will turn yellow and hard after a long time, and bacteria will grow! How to clean and hygienic?

Dehydration of the towel can also make the towel yellow.

Dehydration and uncleanness: If the towel is dehydrated and not clean during washing, the residue of alkaline chemicals will be formed, which will remain in the towel fiber, causing the towel to become hard and reducing the fastness of the towel.

Alkaline chemicals, which are safe for cotton fibers during the washing process and will not damage towel fibers. However, if the dehydration is not clean, the residue of alkaline detergent will remain in the towel fiber, and the towel will become hard and softer after drying.

The residue of chlorine bleach, chlorine bleaching agent is a strong bleaching agent in detergent chemicals, which is somewhat damaging to the cotton fibers in cotton fabrics. It must be used and controlled rationally in the putting wash. If the temperature washing time concentration is well controlled, it is relatively safe, on the contrary, the temperature, concentration, and quantity are not well controlled, and the dehydration is not clean, so that the residual material in the cotton fiber is formed, and the residual substance is harmful to the fiber of the cotton fabric.

It leads to the phenomenon of yellowing and hard hair of towel fabrics.

Standardized handling of washing towels can reduce yellowing.

The use of raw materials should be reasonable and appropriate, according to the operation procedures: the last process of towel washing is to use acid neutralization, if the acid neutralization is not appropriate, it will cause the fabric to turn yellow and gray. In the washing process, due to the high hardness of the water quality, poor water quality and other reasons, it is easy to make the towel gray and yellow.

These phenomena are often neutralized with acids to restore the whiteness of the towel. When using, it should be noted that cotton fibers are afraid of acid and alkali, if they are often washed with acid, the life of the towel can be significantly reduced, so the amount should be controlled. Cotton fabric pH adjuster to 5 5 6 5 The pH value of our human body ** is basically the same.

You can put the towel in the pot, add water to submerge the towel, and then sprinkle a handful of alkaline noodles to cook.

After boiling for 5 minutes, rinse with hot water.

If the towels in the home are used for a long time, the surface of the towel must have some strange smell, and because the uses of the towels in the home are different, so when these towels are used, some stains are also different, and when cleaning the towel, it is necessary to clean the situation according to these stains.

If people continue to use these towels to wipe their hands in the future, then these bacteria will also get to people's hands, so try to ensure the cleanliness of the towel, and use some special cleaning tools when cleaning.

When cleaning the towel, you can add some baking soda powder to the basin, and add baking soda powder according to the corresponding amount, so that it can also ensure that the baking soda powder can play a role in eliminating bacteria for the towel, at this time, do not directly add washing powder, or some other cleaning supplies, first wash with baking soda powder for a period of time, rinse and then wash again with laundry detergent, and then, when drying the towel, you should try to ensure that it is dried in a ventilated place, if there is a condition, The towel can be directly exposed to the sun to help sterilize the towel.

In life, it is also recommended that we try to distinguish between towels for different purposes, because sometimes the towels used in people need to pay more attention to safety, so when choosing a face towel, try to choose some softer materials, and you should also pay attention to frequent cleaning when cleaning, after all, the face is also relatively fragile, so you must take into account the cleanliness of the towel when cleaning the towel, if there is some oil stains on the surface of the towel, Then you can use leftover banana peels from your home or a few drops of lemonade in the water to wash them.
