The present invention relates to a polyester composite yarn and a manufacturing method thereof, and more particularly, to a polyester composite yarn excellent in stretchability, excellent stretchability and excellent volumizing feeling by using physical properties of a yarn and an effect yarn, .
Composite yarns of two or more yarns have been developed with a wide range of efforts to combine the advantages of synthetic fibers and the advantages of spinning yarns into one yarn.
Conventionally, a composite yarn was manufactured by simply folding filaments of synthetic fibers and spun yarns of natural fibers. However, many yarn fabrication techniques have been developed to meet the needs of the consumer and the development of folding technology.
In particular, polyester composite yarns have been developed in many polyester composite yarns capable of adding various functions to the basic excellent physical properties of the polyester.
Conventional polyester composite yarns have been widely used for manufacturing a composite yarn having a bulkiness due to a heat shrinkage difference between two yarns by producing a partially oriented yarn (Partially Oriented Yarn, POY) and a drawn yarn by air entanglement with each other There has been known a method for producing a composite yarn by using polyester fibers produced by incorporating inorganic particles into an effect yarn or by using natural fibers such as acetate and rayon for a unique surface effect of a polyester composite yarn.
