Knitted fabric setting drying method

Abstract

The invention relates to a setting and drying method of knitted fabric. The method ensures that the air volume of an upper air plate is smaller than that of a lower air plate by controlling the air volume of the upper air plate and the lower air plate, can further ensure that integrally upward air force is formed for the knitted fabric when the knitted fabric passes through the air plates while saving electric energy, and ensure that the knitted fabric is not adhered to the lower air plate, thereby being beneficial to heat transfer and exhaust emission during drying, and can avoid undesirablephenomena, such as snag yarn, and is beneficial to the improvement of setting and drying quality of the knitted fabric; the method respectively controls the air volume of the upper air plate and the lower air plate according to knitted fabric with different gram weight, is further beneficial to energy conservation and environment protection, reasonably reduces the air volume according to the knitted fabric with different gram weight, can reduce the longitudinal range and frequency of the knitted fabric when the knitted fabric passes through a drying oven, is beneficial to the improvement of the tightness of the edge of the knitted fabric and the flatness of the knitted fabric, can further improve cloth cover lines of the knitted fabric, such as yarn dyed fabric, and is beneficial to reducing the problem of weft bow.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a method for setting and drying knitted fabrics. Background technique [0002] Styling and drying of knitted fabrics is a necessary process for the production of finished knitted fabrics. The power consumption of the setting drying process accounts for about 90% of the total electricity consumption of the entire knitted fabric production, while the power consumption of power accounts for about 80%. The oven circulation fan of the setting machine is the main source of power consumption. Through upgrading and transformation, it can be operated under frequency conversion without changing the performance of the traditional oven circulating fan, that is, it can be operated under a specific speed condition. In the traditional setting production, the circulation air parameters applied to knitted fabrics have always been in a vague understanding, the parameters are too simple, and the...

Problems solved by technology

Therefore, as long as the motor speed drops a little, the power consumption of the motor will drop significantly

Due to the currently used circulating air parameters are too simple, large air volume is generally used for production, which often results in surplus production air volume and waste of electric energy

[0003] In addition, the circulating air parameters of the traditional setting machine are too simple. In addition to the excessive air volume setting, which causes waste of electric energy, the circulating air parameters do not address the unstable and elastic characteristics of knitted fabrics. The original parameter process of circulating air in production Unreasonable, it is easy to cause the problem of tightness of the fabrics with loose structure (such as single bead ground), or cause inconsistent textures and bow and weft problems of inter-striped fabrics
