Description

Circular knitting machine for double faced velour fabric

The present invention relates to a circular knitting machine for a double-sided velour fabric, and to a circular knitting machine that can produce a double-sided velour letter capable of directing various patterns by controlling pile formation and having excellent shape stability.

As a kind of brushed fabric, velour fabric with excellent thermal insulation and excellent touch is widely used in sports clothes and T-shirts, but the shape is slightly deformed due to the inherent characteristics of the knitted fabric itself, which has a difference in the longitudinal and transverse directions. There is a problem in cutting the garments that have been formalized, so they are rarely applied as formal clothing.

Conventional velour fabrics are knitted through a circular knitting machine in which a sinker and a knitting needle are operated by a single sinker cam and a single-stage knitting cam to form a knitted fabric. If you want to express the loop back to the bottom of the knitted fabric, the fabric is not flat, and the bottom is weak, there is a big disadvantage that the durability of the fabric is weak, so until now most velor fabrics form a pile uniformly throughout the surface. So, if you want to change the appearance of knitted fabric, you can change the length of pile during post-treatment of dough and apply dyeing technique to the surface of fabric by the difference of gloss due to the reflection of light, but the pattern is extremely limited. It was.

However, anyone who is involved in this field is aware that it is necessary to change the organization of the velor fabrics in order to meet the tastes of consumers and to produce high value-added fabrics in order to produce diverse and colorful patterns. Specially designed fabrics have not been developed and the improvement of the knitting circular knitting machine is insignificant. Therefore, it was impossible to knit a new atmosphere with the existing velor circular knitting machine.

As the inventors have also been engaged in the production of velor fabrics, velor fabrics have been developed for a long time and have been worn steadily regardless of age despite being produced in a typical form without any special modification. Despite the downturn, the demand is still intact, but if these velor fabrics are also being renovated to keep pace with the times, changing the appearance patterns will lead to more diversified fields of application and greater demand. He was immersed in improving the velor fabric, thinking that he would be able to catch the spotlight.

As a result, unlike the existing velor circular knitting machine, the knitting cam is composed of two stages so that the knitting of the diagonal pattern is possible, and the gap of the knitting needles is easily and precisely adjusted so that the knitting is evenly formed. By developing a special sinker cam, the knitting fabric is knitted so that there is no difference in elongation in the longitudinal and transverse directions. Since the degree of advancement can be freely controlled, the pile formation can be varied, and thus, an improved circular knitting machine that can display various patterns such as diamond pattern and checkered pattern has been developed.
