How to extend the service life of bed sheets? Several factors determine the service life of the sheets. Frequency of use (called PAR in the industry), fabric characteristics (fiber content, number of yarns, density), and washing formulas all affect the service life of the sheets.
The clothing received by the IFI apparel analysis laboratory generally shows degradation and degradation of cotton fibers. Chemical tests show that oxidized cellulose is damaged. Oxidized cellulose is formed when cotton is degraded in the air by alkaline oxides such as bleach. Many of these damaged sheets show that the sheets contain bleach residues. This indicates insufficient cleaning or excessive bleaching dose used in the washing formula. Excessive use of oxygen bleach during commercial washing is the cause of oxidized cellulose. Bleach has very good whitening and disinfection effect, but the prerequisite is that the dosage must be appropriate.
IFI recommends that adding 0.95Kg of bleach with a concentration of 1% per 45Kg of clothing can extend the life of the fabric and improve the quality of washing. Even this concentration of bleach must be thoroughly neutralized and cleaned. Generally speaking, polyester (50%) cotton (50%) blended sheets can be washed 150 times. 100% cotton sheets have a shorter lifespan, such as the number of yarns and weight.
Another way to extend the service life is to buy sheets with equal folding edges. If the folded edges are equal in size, you can use them backwards, so that the wear will be even.
The most effective way to maintain old coarse cloth sheets
Old coarse cloth sheets are a kind of bed sheet fabric that our older generations have always used. It is easy to buy a pure cotton old coarse cloth sheet, but it is not easy to keep the bed sheets the best. Only the most effective maintenance method can extend the service life of the bed sheets.
1. It is best to rinse the old coarse cloth sheets once before cleaning them. At the same time, wash off the surface slurry and dyeing color according to your personal preferences. It will be softer to use and will not fade very easily during cleaning in the future.
2. Cleaning process of old coarse cloth sheets: First pour the neutral detergent into the water of the washing machine. The water temperature should not exceed 30℃. After the detergent is completely dissolved, put it in. The soaking time should not be too long. Unnecessary fading may occur because using alkaline detergents or water temperatures too high or detergents do not dissolve or soak for too long. At the same time, light-colored products should be washed separately from dark-colored products during cleaning to avoid dyeing each other.
3. When storing old coarse cloth sheets, you must first keep the sheets clean and clean, and fold the sheets neatly and put a certain amount of mothballs in it, but do not come into direct contact with the sheets. It should be placed in a dark place, low humidity and well-ventilated place. Covered products that have not been used for a long time can be dried in the sun before reusing them to make them fluffy.
