Knitted fabric shaping machine is an important equipment used for shaping knitted fabrics in the textile industry.
1. Working Principle
The knitted fabric setting machine mainly uses heating, stretching and cooling processes to stabilize the size of the knitted fabric, make its appearance smooth, and improve its physical properties. When the knitted fabric enters the setting machine, it first passes through the preheating zone to gradually increase the temperature of the fabric and increase its plasticity. Then, the fabric is subjected to transverse and longitudinal tensile forces in the stretching zone. By adjusting the magnitude and direction of the tensile force, the width and length of the fabric can be controlled. Next, the fabric enters the high-temperature setting zone and is heat-set at a specific temperature and time to rearrange the molecular structure of the fabric, thereby achieving the purpose of stabilizing the size. Finally, the fabric passes through the cooling zone to quickly reduce the temperature and fix the setting effect.
2. Main structure
Fabric feeding device: used to smoothly introduce knitted fabric into the setting machine, usually including fabric guide rollers, tension adjustment device, etc.
Preheating zone: It consists of a heating device and a ventilation system, used to preheat the fabric and improve the plasticity of the fabric.
Stretching zone: It consists of a stretching device and a control system for stretching the fabric transversely and longitudinally. The stretching device usually takes the form of a needle plate or cloth clip, which applies stretching force to the fabric through mechanical or pneumatic means.
High temperature setting area: It is composed of heating device and heat preservation device, used for heat setting of fabrics. The temperature and time in the styling area are key factors affecting the styling effect.
Cooling zone: It consists of a cooling device and a ventilation system, used to quickly reduce the temperature of the fabric and fix the styling effect.
Cloth outlet device: used to smoothly lead the shaped knitted fabric out of the shaping machine, usually including cloth guide rollers, winding devices, etc.
3. Features
Good shaping effect: It can accurately control parameters such as temperature, tension and time, which significantly improves the dimensional stability and appearance quality of knitted fabrics.
High production efficiency: high degree of automation, easy operation, can achieve continuous production, greatly improving production efficiency.
Strong adaptability: It can be applied to knitted fabrics of different types and specifications to meet the needs of different customers.
Energy saving and environmental protection: adopt advanced heating technology and energy-saving measures to reduce energy consumption and reduce pollution to the environment.
4. Application areas
Knitted fabric shaping machines are widely used in textile printing and dyeing, garment processing and other industries. In the textile printing and dyeing industry, they are used to finish knitted fabrics to improve the quality and added value of fabrics. In the garment processing industry, they are used to pre-shrink and shape garment fabrics to ensure the dimensional stability and appearance quality of garments.
Knitted fabric shaping machine is an indispensable and important equipment in the textile industry. Its performance and quality directly affect the production efficiency and product quality of knitted fabrics. With the continuous development of textile technology, knitted fabric shaping machine is also constantly being improved and innovated to meet the needs of the market.
