Hotel linen washing and maintenance - Music in Japan

One or several improper washing method is easy to cause damage:


( 1) Washing wrong feeding time: when the machine under the condition of water shortage in weight, especially pay attention to the bleaching chemicals, so easy to make detergent focused on local linen and cause damage.


（ 2) Improper use of bleach. The misuse of detergent, for different stains, choose suitable products.


（ 3) Washing the dosage too much, not completely clean, residue on clothes.


（ 4) A zippered clothing and silk pilling wash mix.


2, clothes drying and air basks in


note the fabric of different fabrics, choose corresponding drying temperature ( There are instructions on general dryers are) 。 Filling material items, is the core, pillow core, blankets, etc. Can be directly in the sun insolates, flap with the hand a few times. So dark fabric, facing the sun, silk fabric is unfavorable the sun insolates, should dries.


3, storage, change garments according to the items after dry had better use a compact bag, store to the dry and ventilated place.


4, several kinds of linen fabric normal about the service life of the machine:


pure cotton bed sheet and pillowcase, 130 - 150 times, blending, 35% cotton) 180 - 100-220, towel categories: 110 times. Table cloth, dinner cloth: 120 130 times.





5, the common problems in the process of washing and processing methods:


1, bed sheets, Table cloth) With oxalic acid to get rid of rust stains and the later, into the washing machine, after washing, found rust stains has not been removed. Acidizing is the last procedure in the process of washing, acid agent quality is critical in the laundry supplies, it can make up the defects and shortcomings of previous working procedure, make wash perfection, achieve the ideal state.

some laundry commonly used oxalic acid, this is unsatisfactory. Without the softened water can form calcium oxalate precipitation, adsorption on the fabric, the fabric grey, harden and become fragile. Using oxalic acid rust removal is in addition to the net, temporary. This reaction Fe++ + ( Tan) 铁+ + ( Light green) Is reversible reaction, residue on the fabric Fe++ classics drying, the time will see again into Fe++ + air oxidation, only other acid complexing agent is added in the oxalic acid or use the method of removal of rust of other compounds, make its can form stable complex or chelate.


2, when washing f&b small squares, using a special laundry powder and chlorine bleaching powder, sodium hypochlorite, but the effect not beautiful, a gray serious reason:


1) first of all to understand before washing washing water quality properties of square area, is soft or hard water, if it is a hard water, means that a high content of calcium and magnesium ions and metal ions, so must add softener when washing, must use neutralizer in the post-processing.


2) washing the towels, had better use oxygen bleaching powder with detergent to wash, do not use chlorine bleaching powder, because the chlorine bleaching powder is strong oxidizing, the towel is easy to damage.


3. Hard water can produce calcium magnesium ions to form calcium magnesium soap, calcium and magnesium soap itself is a kind of dirt, known as soap scum or alkali flowers. Calcium magnesium soap residual dirt is difficult to remove all, accumulated for a long time it will destroy the fiber and the pigment, make clothes, cotton slightly hard, lose luster, and change the colors, the harmfulness of the fiber is large, crisp, broken, fastness to reduce wait for a phenomenon. Exists in the form of iron in water by ion or ionic compounds, such as deposit or become brown spots on the fabric, can make the white fabric whole yellow, bringing color fabric colour and lustre is dim, and the bleaching agent has certain catalysis, serious still can cause fabric damage.
