Description

A loop yarn and fabrics therefrom The present invention relates to a loop yarn and a fabric manufactured therefrom, and more specifically, to a loop yarn comprising a core, an effect yarn that winds the core, and a fastening yarn that binds the effect yarn to the core and forms loops at desired intervals and heights, and a fabric manufactured therefrom. Generally, loop yarn is a fiber in which a loop is formed on one side of the fiber. It has excellent elasticity, as well as thermal insulation, sound absorption, and abrasion resistance, and has a soft touch. It is used in wool, silk, cotton, and synthetic fiber fabrics, and is used in the manufacture of carpets, chair covers, clothing fabrics, sportswear, cold-weather clothing, formal wear, etc. Looking at the prior art related to the above loop yarn, Korean Published Patent Application No. 10-2009-0003676 discloses a manufacturing apparatus for metallic loop yarn characterized by having a plurality of supply rollers that supply yarn by optionally providing a yarn supply roller, a bobbin that winds the decorative yarn, a spindle that rotates by being connected to a servo motor through a belt chain and a rotating shaft, and the servo motor including a control unit. Korean Published Patent Application No. 10-2009-0124465 discloses a method for manufacturing a shearing pattern knitted fabric of Jacquard loop yarn, in which a Jacquard loop yarn is overlaid and woven onto an existing loop on a letter-shaped surface, in which a loop woven as a warp is connected to an adjacent loop to form a wale, thereby expressing a pattern. However, loop yarns according to conventional technology had the disadvantage of not being usable for various applications because the spacing or size of the loops formed on the surface could not be controlled. Furthermore, there is a need to develop new fiber materials manufactured by recycling conventionally discarded polyester, as well as to develop eco-friendly, high-value-added fiber products. FIG. 1 is a schematic diagram of a loop wire according to the present invention, and FIG. 2 is a schematic cross-sectional view of a sea-island type polyester yarn according to the present invention, and Figure 3 is an enlarged cross-sectional photograph of a sea-island type polyester yarn according to the present invention. In this application, terms such as “comprising,” “having,” or “comprising” are intended to specify the existence of the features, numbers, steps, components, parts, or combinations thereof described in the specification, and should not be understood as precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which this invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. Below, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. To facilitate overall understanding in describing the present invention, the same reference numerals are used for identical components in the drawings, and redundant descriptions of identical components are omitted. Hereinafter, the loop yarn (200) according to the present invention and the fabric manufactured therefrom will be described in detail with reference to the attached drawings. Fig. 1 attached to the present invention is a schematic diagram of the loop yarn (200) according to the present invention, Fig. 2 is a schematic cross-sectional diagram of the sea-island type polyester yarn (100) according to the present invention, and Fig. 3 is an enlarged cross-sectional photograph of the sea-island type polyester yarn (100) according to the present invention. The loop yarn (200) according to the present invention may preferably comprise, as shown in FIG. 1, a core yarn (110), an effect yarn (120) that forms a loop while winding the core yarn (110), and a fastening yarn (130) that binds the effect yarn (120) to the core yarn (110) to form a loop of a desired size, spacing, and height. The loop yarn (200) according to the present invention can be manufactured through a twisting process using a twisting machine. The twisting process refers to a process of manufacturing the loop yarn (200) by twisting together a core yarn (110), an effect yarn (120) that forms a loop on the surface of the core yarn (110), and a fastening yarn (130) that fastens and binds the effect yarn (120) to the core yarn (110) using a twisting machine. According to the present invention, the loop yarn (200) passes the polyester sea-island yarn used as the core y
