Description

Technical Field

[0001] This application relates to the field of textile technology, and more specifically, to a fabric stenter oven and its hot air nozzle. Background Art

[0002] The stenter uses hot air drying technology to conduct key post-treatment on fabrics, playing a crucial role in the printing and dyeing production process. This process can not only quickly and evenly evaporate the moisture in the fabric, ensuring the dimensional consistency and smooth and tidy appearance of the fabric, but also optimize the tactile sensation, anti-slip property, color and other characteristics of the fabric by finely adjusting the temperature and wind speed, thereby improving the overall quality and market competitiveness of the fabric. In addition, this process also helps to achieve energy conservation and consumption reduction, meeting the environmental protection production standards.

[0003] However, when drying fabrics, the commonly used hot air nozzles in current stenter ovens often blow vertically towards the fabric surface. This vertical hot air is blocked by the fabric fibers and is difficult to quickly penetrate deep into the fabric, resulting in a reduced heating efficiency. At the same time, if the fabric is thick, the temperature difference between the surface and the inside will cause uneven shrinkage rates in each part, affecting the dimensional stability of the fabric and possibly causing shrinkage during subsequent use. In addition, the direct impact of the vertical blowing on the fabric may also cause the fabric surface to be uneven or damaged, thereby affecting the hand feeling and appearance quality of the fabric. Therefore, improving the design of the hot air nozzle to enable more effective drying of the fabric is the key to enhancing the performance of the stenter. Summary of the Utility Model

[0004] One advantage of this application is to provide a fabric stenter oven and its hot air nozzle, wherein, by setting the inclination angle of the air holes, the hot air is formed to blow obliquely towards the fabric surface, which is beneficial for the hot air to pass through the gaps between the fabric fibers and penetrate deep into the fabric layer, so that each part of the fabric is evenly heated, thereby keeping the shrinkage rates of each part of the fabric consistent, improving the fabric setting effect, and enhancing the fabric quality.

[0005] One advantage of this application is to provide a fabric stenter oven and its hot air nozzle, wherein, through the inclined air outlet, the hot air can be closer to the fabric, enabling the hot air to more effectively penetrate the fabric and improving the heat transfer efficiency.

[0006] One advantage of this application is to provide a fabric stenter oven and its hot air nozzle, wherein, the inclined air outlet design can reduce the waste of hot air, because the hot air acts more directly on the fabric, reducing heat dissipation, thereby reducing energy consumption.
