Precautions for purchasing and cleaning pure cotton women's T-shirts

Cotton T-shirts are very popular in summer, especially among female friends. The advantages and disadvantages of pure cotton T-shirts coexist. Here are some warm tips for the characteristics of pure cotton T-shirts.
Firstly, what should I pay attention to when choosing a pure cotton T-shirt?
1. The shrinkage rate of cotton knitted underwear is relatively high. When purchasing, it is necessary to first choose products with dense fabric organization, fine workmanship, and complete identification. At the same time, it should also be noted that the model should be appropriately larger to allow for shrinkage.
2. Pay attention to the safety indicators of pure cotton and cotton containing clothing. When choosing pure cotton underwear, it is necessary to avoid choosing dark colors, pigment prints, and clothing that has undergone soft, firm, and iron-free processing.
3. Simple identification can be performed during purchase.
a. Touch. Pure cotton fabric has a plump and thick feel, and looks like a fabric of the same thickness. Pure cotton has muscles and bones when touched.
b. Look. Is there any "aurora" in pure cotton fabric? Use both hands to flatten the fabric, and apply a certain amount of tension. The fabric and body should be at a 45 degree angle downwards. Look at the light source to see if there is dazzling light. If there is, it indicates the presence of chemical fibers.
c. Pinch. After kneading pure cotton, there are obvious wrinkles. Fold the fabric in half and use a nail to scrape it. After unfolding, there are clear creases. After kneading the synthetic fiber fabric, there are no wrinkles.
d. Burn. The cotton fibers do not melt or shrink when close to the flame, and immediately burn when in contact with the fire. When burned, there is a smell of burning paper, and after being burned out, they appear as fine and soft gray black and white flocculent ashes without coking.
