Pure cotton, cotton, and linen fabric clothing: This type of clothing can generally be placed directly in the sun, because the strength of this type of fiber in the sun hardly decreases, or slightly decreases, but it will not be deformed. However, in order to avoid fading, it is best to face outwards.
Chemical fiber fabric clothes: Chemical fiber clothes should not be exposed to sunlight after washing. Because acrylic fiber is easy to change color and yellow after exposure; nylon, polypropylene, and man-made fibers are easy to age when exposed to sunlight; polyester and Velen will accelerate the photochemical pyrolysis of fibers under the action of sunlight and affect the life of the fabric. Therefore, it is better to dry chemical fiber clothes in the shade.
Wool fabric clothing: After washing, it should also be placed in a cool and ventilated place to allow it to dry naturally, and the reverse side should face outward. Because the surface of the wool fiber is a scaly layer, the natural oleylamine film on the outside gives the wool fiber a soft luster. If exposed to the sun, the oleylamine film on the surface will deteriorate due to high-temperature oxidation, which will seriously affect its appearance and service life.
Woolen sweaters, sweaters, and other knitted fabrics: In order to prevent this kind of clothing from deforming, you can put them in a net bag after washing and hang them in a ventilated place to dry; or hang them on two hangers when drying to avoid overhanging. It is heavy and deformed; it can also be strung up with bamboo poles or plastic pipes to dry; if conditions permit, it can be laid flat on other objects to dry. In short, avoid exposure or baking.
