Washing and maintenance methods of hotel bedding

1) Pay attention to product classification and washing: * Bedclothes: sheets, bedspreads, quilt covers, pillowcases and bathrobes.

2) Washing according to different pollution levels.

3) Separate washing according to the depth of linen.

4) Wash old and new linen separately. The natural damage and abnormal damage of old hemp should be treated differently, and the dehydration time of new and old hemp is different with different strength.

5) Different fabric components should be washed separately. (such as pure cotton, polyester cotton, silk)

Second, choose different washing methods for different products, such as dry cleaning, water washing and ironing. Quilts, pillows and blankets are not suitable for washing.

Third, check the machine frequently, be careful in the process of collecting and transporting linen to prevent secondary pollution and man-made damage, and load it properly when washing. Too much or too little will affect the cleanliness and wear of linen. Set the program according to the different washing severity of products. For example, compared with bed sheets and mouth cloth products, towel products have lower dehydration speed and shorter time.

Fourth, pay attention to check whether there are hard objects (coins, keys, needle scissors, lighters, etc. ) put it in the items before washing. So as not to damage the machine and clothes. Empty the machine and check whether there are sharp and iron impurities in the drum of the machine.

5. Pay attention to the water quality in this area: use soft water. If the water quality is hard, it's better to treat it.

Six, the correct use of detergent, grasp the reasonable feeding time and temperature, understand the basic characteristics and usage of detergent, avoid direct contact with strong acidic or corrosive chemicals. Stubborn stains should be soaked in warm water (about 40 degrees) and corresponding detergent 1-2 hours. Dark clothes should not be bleached with chlorine, washed locally and washed in a large area.

Seven, easy to cause snagging or deformation items need to be packed in laundry bags.

Eight, several improper washing methods are easy to cause damage:

1) Incorrect feeding time during washing: When the water in the machine is insufficient, special attention should be paid to bleaching chemicals, which tend to concentrate detergent on linen and cause damage.

2) Improper use of bleach. If you misuse detergent, you should choose the right product according to different stains. 3) Too many times of washing, incomplete cleaning and residue on clothes.

4) Clothes with zippers are mixed with clothes that are easy to snag and pilling. 9. Drying and drying of clothes: Pay attention to the fabrics of different fabrics and choose the corresponding drying temperature (generally indicated on the dryer). Filler, quilt, pillow core, blanket, etc. You can directly expose yourself to the sun and pat it with your hands. If the fabric is dark, the opposite side is facing the sun, and the silk fabric should not be exposed to the sun, but should be cooled down.

Ten, storage, seasonal goods had better be packed in dense bags after drying and stored in a dry and ventilated place. XI。 The approximate service life of several linen fabrics in normal machine washing: cotton bed sheet pillowcase: 130- 150 times, blended fabric (cotton 35%) 180-220 times, towel: 100- 165438+. Table cloth and mouth cloth: 120- 130 times.

Twelve, common problems in the process of washing and treatment methods:

1. There are rust spots on the sheets (tablecloths). After treatment with oxalic acid, put it into the machine for cleaning. After washing, I found that the rust spots had not been removed. Acidification is the last process in the laundry process, and the quality of acidifier is very important in laundry products, which can make up for the defects and deficiencies in the previous process and make the laundry perfect and reach an ideal state. Some laundry rooms often use oxalic acid, which is not enough. Calcium oxalate precipitation will be formed in the water without softening, which will be adsorbed on the fabric, making the fabric gray, hard and brittle. Rust removal with oxalic acid is unclean and temporary. The reaction between Fe++(tan) and f e++ (light green) is reversible. After drying, the residual Fe++ on the fabric was oxidized by air for a long time and became f e++ again. Only by adding other acidic complexing agents or using other rust-removing compounds to form stable complexes or chelates can they be removed.

2. When washing small square towels in the catering department, we used whitening powder, chlorine bleaching powder and sodium hypochlorite special for laundry room, and the results were not good, and the reasons for serious ash flooding were as follows: ① Before washing, we must first understand the water quality in the square towel area, whether it is soft water or hard water. If it is hard water, it means that the content of calcium and magnesium ions and metal ions is high, so a water softener must be added when washing, and a neutralizer should be used when post-processing. (2) When washing towels, it is best to wash them with oxygen bleaching powder and washing powder, instead of chlorine bleaching powder, because chlorine bleaching powder has strong oxidation and is easy to damage towels. 3 Hard water can produce calcium and magnesium ions to form calcium and magnesium soap, which is a kind of dirt itself, commonly known as soap scale or alkali flower. It is difficult to remove the residual scale of calcium magnesium soap. If it is accumulated for a long time, it will destroy fibers and pigments, make clothes and cotton fabrics slightly hard and lose luster, and change the color light, which will do great harm to fibers, become brittle and broken, and reduce the fastness. Iron exists in the form of ions or ionic compounds in water. If it is deposited on the fabric or becomes brown spots, it will make the whole white fabric yellow, darken the color of colored fabric, catalyze bleaching agent to some extent, and even cause fabric damage.
