What Are the Characteristics of Garment PRocessing And Load Characteristics of Industrial Sewing Machines?
Apr 18, 2020

The textile and apparel industry is related to our life and is one of the pillar industries of China's export earning foreign exchange. As garment processing machinery, industrial sewing machines are used more and more. At present, most industrial sewing machines use single-phase and three-phase AC asynchronous motors. Generally, they have only one processing speed, which is difficult to adapt to the processing requirements of various apparel fabrics. If the transmission mechanism is used to change the speed, the efficiency will decrease. From the aspects of improving processing quality and processing efficiency, saving energy, etc., applying variable frequency speed regulation technology to industrial sewing machines can achieve satisfactory results.

Characteristics of garment processing

There are many types of clothing, different fabrics, such as thin summer clothing and thick winter clothing; thin silk and thick fabrics, and various clothing and fabrics have different requirements for the speed of sewing and the torque of sewing. Generally speaking, summer clothing and thin fabrics require fast sewing speed and small torque to improve work efficiency; winter clothing and thick fabrics require slow sewing speed and large torque, to

Needle-break-free, and the number of layers of the fabric in the processing process has different requirements on speed and torque. Therefore, how to select the sewing speed and torque according to the actual situation of the fabric is the key to improving work efficiency and ensuring processing quality. At present, the power used by industrial sewing machines is single- and three-phase clutch motors, which generally have only one speed. As usual, high-power four-pole motors are used for winter clothing and thick fabrics; two-pole motors with lower power are used for summer clothing and thin fabrics, and then they are adjusted with belt wheels Speed, so it is difficult to achieve the universality of the equipment, and it is impossible to achieve stepless speed regulation according to the conditions of clothing and fabrics, which is low in efficiency, large in energy consumption, and difficult to guarantee quality.

Load characteristics of industrial sewing machines

According to the processing characteristics of clothing and fabrics, the stitch speed of the sewing machine depends on the rotation speed of the motor, and the size of the sewing force depends on the output torque of the motor. In the high speed section, the processing speed of the thin fabric is generally fast and the torque is small; the processing speed of the thick fabric is slow and the torque is large, and its processing power remains unchanged, with a constant power load characteristic, while in the low speed section, the maximum sewing force allowed is the same, The load torque is also the same and belongs to the constant torque area.
