The present invention relates to a circular knitting machine for use in synthetic resins and woven nets thereof, and more particularly, to weave synthetic resin yarns made of monofilament, polypropylene, polyethylene, etc. in a net form. The present invention relates to a circular knitting machine and a net woven by the circular knitting machine to form a loop by the action of the sinker pin in consideration of the fact that the synthetic resin is highly elastic in forming the knitting part and the sinker part.

In general, fabrics woven by a loom are made of warp and weft yarns crossing each other up and down to form a cloth of a predetermined width, and various patterns or patterns can be formed according to the weaving method. As one of looms for weaving, circular knitting machines are common.

The circular knitting machine includes a knitting portion composed of a knitting needle (needle) vertically reciprocating by a knitting cam, and a sinker portion composed of a sinker (horizontal reciprocating movement) by a sinker cam, and controls a vertical direction of the knitting needle (needle). Through the various designs of the knitting part and the sinker part for controlling the horizontal direction of the yarn, we can weave various shapes of fabric, and also change the weaving pattern accordingly.

The material used to weave these fabrics is mainly made from natural fibers such as silk yarn, and chemically processed synthetic yarn such as nylon yarn. Since these yarns are very flexible and have no strength, various weaving methods can be applied when weaving fabrics. have.

However, the monofilament yarn mainly used as a fishing line or polypropylene yarn or polyethylene yarn, which is equivalent thereto, has a high strength and tensile force, a relatively low flexibility, and a very high elasticity, so it is a synthetic resin yarn such as monofilament of 0.3 mm or more. In general, not only can not be woven as a widely used circular knitting machine, there is a problem that can hardly woven a synthetic resin net by applying a weaving method such as a general cloth including a double-sided single.

The synthetic resin net is expected to be applied to various fields such as bed mattresses, building materials, and geotextiles because of its high strength, tensile strength, and elasticity.However, when using circular knitting machines, a general and general technique for weaving synthetic resin yarns has been developed. There is no situation yet.

Accordingly, the present invention has been made to solve the above problems, the present invention is vertically linked to the knitting cam in weaving a synthetic resin yarn made of monofilament yarn, polypropylene yarn, polyethylene yarn, etc., which is a high-strength and high-elastic material While weaving a simple structure of a synthetic resin net that is woven by forming single and loops in a plurality of synthetic resin yarns spaced by a certain distance by a moving knitting needle and a sinker cam moving horizontally in conjunction with a sinker cam, weaving it quickly and easily It is an object of the present invention to provide a circular knitting machine and a synthetic resin net manufactured by the apparatus.
