(Summary description)The application of quartz infrared (QIR) technology in the textile drying industry has revolutionized the way fabrics are handled and processed. Quartz-infrared radiation technology, with its unique heating properties, has been shown to be beneficial in improving the quality and functionality of textiles drying.

 

Quartz-infrared heating technology can be used in the bleaching, dyeing, sizing and shaping of various cotton, wool, silk and chemical fiber fabrics. The prebaking, shaping, hot-melting, and heating of baking equipment for synthetic fiber blended fabrics generally use convection, conduction, etc. methods. Among them, the thermal efficiency of hot air convection heating is only about 30%. The new technology of quartz-infrared radiation has the advantages of fast heating speed, low energy loss, good product quality and small equipment footprint. Therefore, in recent years, quartz-infrared heating have been gradually promoted and used in the printing and dyeing industry.

 



 

When quartz-infrared heating reach an object, the following three situations will occur: part is reflected on the surface of the object, part is absorbed by the object, and the rest is transmitted through the object. The absorbed infrared radiation energy is converted into heat, causing the object to heat up. The greater the energy absorbed, the higher the temperature of the object rises. When applying quartz-infrared heating, we hope that the reflection and transmittance of the heated object are smaller and the absorptivity is larger.

 

For this reason, the wavelength of infrared radiation is required to match the absorption wave of the heated object. Inorganic substances such as water, water vapor and glass, as well as most organic substances and polymer substances, can absorb infrared heating, and can strongly absorb quartz-infrared heating. The dry heat treatment of synthetic fiber fabrics and the pre-drying of dyeing use this characteristic to reduce energy consumption and improved quality.

 

The setting of synthetic fiber fabrics requires the time required for the cloth surface to be heated to the setting temperature after the fabric enters the setting machine, and then further penetrates into the fabric to reach between the fiber molecules, and is adjusted according to the setting conditions. quartz-infrared radiation can radiate directly to the heated fabric and has two characteristics: transmission and absorption. After absorbing quartz-infrared energy of a certain wavelength, the molecules and atoms of the heated fabric vibrate and rotate intensified, increasing the energy of movement, causing the fabric to absorb heat and heat itself. It is much faster than convection heating and is used for hot melting of disperse dyes. Dyeing can shorten the hot melting time or lower the hot melting temperature. Similarly, the use of quartz-infrared resin baking with the help of a catalyst can complete the cross-linking reaction between the resin and the fiber in a short time.

 

In summary, quartz-infrared technology has become a game-changer for the textile industry. Its application in dyeing and finishing, functional textiles, smart textiles and other fields has brought significant improvements in efficiency, quality and functionality.
