Our engineering and technical personnel found that most of the holes in the towel were irregular. We observed the brittle and discolored parts with a microscope and found that the mildew on the fiber surface was obvious, and the fiber mold colony could still be detected after washing. Crisp and damaged towels are stored in damp-heat and stuffy containers after washing or wiping sweat. The longer they are stored, the more severe the crisp and damaged. There are also new towels that are broken once washed. These towels are pulp towels without washing and Desizing. The starch pulp is exactly the nutrient base of mold. Once the environment conditions of damp heat and depression are met, mold will rapidly breed and reproduce and secrete enzymes to convert fiber and amylolysis into glucose. At the same time, dander contained in sweat (containing inorganic salts such as protein, fat, amino acid, potassium and sodium) further promotes the reproduction of bacteria and other microorganisms and releases acidic substances, it is not only beneficial to the survival of bacteria, but also accelerates the hydrolysis of starch and fiber. Therefore, after the new towel is used or with unwashed starch pulp, it will become moldy and brittle in the humid and unventilated environment.

Therefore, if you find that the towel has a sticky feeling and is accompanied by cacosmia, you should wash it with soap and dry it in a ventilated place as soon as possible. The newly produced towels must be decompressed, dried and cooled, and then packaged and stored. Do not store them in a humid and stuffy environment for too long to avoid mildew.

3. How to distinguish the quality of towels

First. Appearance observation: the towel is finely sewn, piping neat, consistent in width and width, horizontal and vertical, non-oblique and non-twisted, consistent in tightness, neat in wool, upright in velvet circles; Wrist splint towel is straight in sight, the velvet ring is bright and clean, and it is better if it is rare to have cotton velvet outside. It is better if the color is pure and bright without uneven depth.

Second, hand touch: a good pure cotton towel feels fluffy, soft and smooth. It is soft and elastic to hold in the palm, and there is no lint falling off.

Third. Smell: good towels have no smell. If there is a smell of candles or ammonia, it means that softening agent is excessive; If there is a sour taste, the pH value may exceed the standard; If there is a pungent smell, it means that color fixing agent containing formaldehyde is used, and free formaldehyde is precipitated.

Fourth. Hygroscopicity test: the towel is hung with hands and then thrown to the towel. The water drops do not roll down, indicating that the absorption and diffusion are rapid and the moisture absorption is good. If the water drops, it indicates that the softening agent in the towel is excessive or the refining is insufficient.

Fifth. Color fastness test: first pour the hot water of about 80 degrees into the basin, and then put it into a towel to wash it up and down. If there is no color in the water in the basin, it is better; If there is color falling, it indicates that the dyeing quality is poor, which hinders human health. Such towels are "washing face with industrial waste water" according to the words of Mr. Yang Donghui, president of China Home Textile Association ".
