Fashion sweater makes you look beautiful or handsome. But you should wash it carefully to keep it stylish and neat. There are the new method to wash a sweater.
Before the new sweater is on the upper body, it should be cleaned first and then maintained with a professional clothing care agent, such as the gold-woven clothing care agent commonly found on the market. Add water to the sweater and soak it in a sweater. This will add a protective film to the new sweater, which will not only make the sweater bright and not deform, but also make the stains easier to remove.
Sweaters should not be washed by washing machine. If hand-washed, it means that you can use up to 40 °C warm water and special detergent. Flip the inner layer of the sweater into a fully dissolved detergent for 3 minutes, and slowly squeeze the sweater until it is soaked.
Wash with warm water, then rinse with cold water, and finally add diluted clothing care agent, which can play the role of smooth fiber, greatly reduce the possibility of static accumulation on the sweater, while also helping the fiber to restore its original elasticity. Make the sweater not easy to deform and bright as new.
When drying, you need to put the sweater flat and dry. It is best to choose a good quality clothes basket to avoid falling and causing deformation of the waist and sleeves.
Of course, the maintenance should be extraordinarily careful.
First, if the sweater material is natural, such as wool and cotton, it must be dry-cleaned to not deform or fade. If the processed fabric is washed, it can be washed with water, but no matter what kind of clothing, it must be ironed after washing to avoid wrinkles.
Second, wool is not resistant to alkali, so it should be washed with a neutral detergent. Wool fabrics should shrink and deform in an aqueous solution above 30 °C, so the temperature of the washing bath should not exceed 40 °C. Do not wash with a slab during washing, and the washing time should not be too long to prevent fluffing.
At last, do not twist after washing, squeeze by hand to remove moisture and then drain. It takes half a minute to dehydrate with a washing machine. Dry in a cool, ventilated place. Do not expose to strong sunlight, to prevent the fabric from losing its luster and elasticity and causing a strong drop.
