Common Moisture Regain Standard And On-Line Detection Method For Common Raw Materials

The moisture absorption of textile raw materials is an important characteristic related to material properties and processing technology. The hygroscopicity of textile materials is usually expressed by moisture regain and fixed moisture regain. These basic quality indexes play an important role in the commercial trade, performance test and textile processing of textile materials. The weight of textile materials varies with moisture regain.

I. definition of moisture regain of textile raw materials

In the textile industry, moisture regain refers to the percentage of the moisture content of the fiber to the dry weight of the fiber, that is, the moisture regain = (wet weight of fiber - dry weight of fiber) / dry weight of fiber * 100%. The common moisture regain is the moisture regain stipulated by the state for textile raw materials and textiles for the needs of inspection and trade.

Standard of moisture regain of textile raw materials

At present, the moisture regain standard state of China's textile industry is 65% ± 3% humidity and 20 ℃ temperature. Generally called standard state. The moisture regain of fiber in standard state is called standard moisture regain. In the calculation of trade and cost, fibers are not all in the standard state. In order to make the pricing reasonable and fair, the moisture regain of all kinds of fibers is uniformly stipulated, which is called the common moisture regain, which is close to the standard moisture regain, but not equal to.

　　 On line detection method of moisture regain of textile raw materials

German mosye near infrared moisture regain detector ms-a-580 is suitable for on-line dynamic continuous measurement of moisture content of cloth on production lines of various textile enterprises.

Moisture regain detector ms-a-580
