Vosges Home Textiles Different Methods to Identify the Quality of Towels
If you visit the towel market, you will find that a towel, the price difference between the brands is very different, the same price of a towel with different textures can reach 10 times higher than the price. What standard should we use for the towel we use every day? Is it easy to identify a simple method? Jiang Xiankai, an associate professor at the College of Chemistry, Chemical Engineering and Materials of Heilongjiang University, directed the reporters to conduct experiments. Experiment 1 immersion test Take out two towels with different prices and start the towel soaking experiment. Put the appropriate hot water in two identical containers and put the two towels one by one into the container. First of all, when the reporter immersed the blue towel bought in the market with 1 yuan into the water, the water immediately turned blue; when the towel bought with 10 yuan was immersed in water, the water did not change any color. Experimental results: the color fade is also slow Through the above experiments, it is found that the color of the towel is also slow. According to reports, because the main reason for unqualified towels is that the water absorption and color fastness are not up to standard, the towels with poor color fastness will obviously fade, and the quality is also discounted. In general, a good quality towel will only wash off some of the floating color during the first cleaning. If it fades every time, it is best not to wash your face with this quality towel, otherwise it will be like using "chemical dyes" to wash your face. Over time, it will cause damage to the skin. Test two water absorption test The water absorption of the towel was determined by the sedimentation method: a towel of the same size was selected, and the water absorption property was judged by the speed of the time required for it to wet. Count with a stopwatch. The first "testing water" is a blue, green and red pattern of towels. Put the towel on the water and press the stopwatch to "start". After seeing the towel, I started to absorb water immediately. Due to the absorption of moisture, the corners of the towel began to sink into the water, and only some of the surface of the fluff was exposed on the water. After that, as the amount of water absorption increases, the entire towel is wetted by water. Pressing "Stop" takes 11 seconds before and after. Followed by a red plaid towel. I saw the towel sinking into the water and began to sink. After a while, it was completely wet, and it took only 6 seconds. After the colored towel is put into the water, 10 floats on the water. After 5 minutes, the towel did not mean to absorb water, and it still floated on the water. Experimental results: towel absorption is regular Through the test, it was found that the towel absorbs water regularly. That is, the corners first absorb water, then the middle. A towel that absorbs water quickly appears to be evenly sunk due to its high penetration rate. However, if it is slower to absorb water, like the first towel, the corners are already suspended in the water, and some of them are dry in the middle, and a curved surface appears. But when you finally get enough water, you will sink to the bottom. According to experts, the quality of absorbent towels is good.

Towels are a must-have for everyone, because they are in direct contact with our skin every day, so many families do not regularly replace towels, which are often disinfected and cooked. The purpose is to make the towels comfortable and hygienic. However, some towels, even if you carefully clean and disinfect them, I am afraid there will still be problems. Recently, Ms. Chen of Harbin was worried about the towel. As a hospital pharmacist, Ms. Chen has good hygiene habits. Every year, she buys a lot of towels for timely replacement. But this time, Ms. Chen found that the newly bought towel was particularly easy to fade when it was wet. Ms. Chen said that the faded towel made her very uneasy.
