Description

YARN AND MANUFACTURE METHOD THEREOF

Technical Field

The present invention relates to a yarn, and more particularly, to a yarn containing a functional powder such as Tourmaline or Monazite and having a coating layer formed on its outer diameter, and a manufacture method thereof, and woven fabrics and textile articles obtained from the yarn.

Background Art

As well known in the art, Tourmaline belonging to a hexagonal system refers to a mineral being a kind of an igneous rock, naturally generating positive and negative polarities at both ends of a crystal, and having a property of generating a potential difference of one million volts and generating a permanent weak current. The Tourmaline has a rigidity of 7.0 to 7.5, and has a specific gravity of 2.98 to 3.20. The Tourmaline has a chemical component of borosilicate being a complex of iron, magnesium, alkali metal, and aluminum, and is a kind of a healthy precious stone such as a uranium ore and a magnetite, for storing energy of itself and endlessly emitting the energy, thereby energizing a human body.

As effects of the Tourmaline, it is known that, due to its weak heat, particles generate electricity, and a weak current flows to be in association with a body heat, thereby transmitting and keeping the heat, and an acupuncture point is stimulated and a peripheral circulating system is improved, thereby facilitating a blood flow, and anions are generated, thereby providing effects of anti-bacteria, deodorization, and cleaning. The Tourmaline has an effect of an electrostatic potential therapy such as improvement of physical constitution and cleaning of blood, due to cell activation. In particular, far infrared rays and the anions emitting from the Tourmaline result in an operation and effect of alleviation of neuralgia, arthritis, and backache, glycosuria, constipation-ache, deodorization, anti-bacteria, dehumidification, softening of water, and air cleaning, thereby being in trend of gradually spreading for use in a construction field, an environment field, and a medical field.

Meantime, the Monazite belonging to a monoclinic system is a phosphate mineral of a cerium group rare earth element, has a rigidity of 5 to 5.5 and a specific gravity of 4.6 to 5.4, and generates a large amount of anions and far infrared rays .

FIG. 3 illustrates woven fabrics obtained from the yarn of FIG. 1;

FIG. 4 illustrates clothes being textile articles obtained from the fabrics of FIG. 3; and FIG. 5 illustrates a yarn containing a functional powder according to the second embodiment of the present invention.

Best: Mode for Carrying out the Invention Hereinafter, preferred embodiments of the present invention will be described in detail with reference to accompanying drawings.

FIG. 1 illustrates a yarn containing a Tourmaline powder being a functional powder according to the first embodiment of the present invention.

As shown in FIG. 1, the yarn 10 containing the Tourmaline powder includes a core yarn 20, and a coating layer 40 coated on an outer diameter of the core yarn 20.

The core yarn 20 corresponds to a center of the yarn 10, and is formed by melting and extruding polyester being a synthetic resin material. It is desirable that the melted core yarn 20 is mixed with the Tourmaline powder 30 and is extruded together with the Tourmaline powder 30, thereby forming the core yarn 20.

The coating layer 40 is a layer for coating and sealing the outer diameter of the core yarn 20 so that the Tourmaline powder 30 mixed with the core yarn 20 is not separated and broken out from the core yarn 20 in course of use. In other words, the Tourmaline powder 30 can be kept for a long time within the core yarn 20 by the coating layer 40, so that the core yarn 10 can show for a long time a functionality of the Tourmaline powder 30. The coating layer 40 preferably employs polyester that is the same material as the core yarn 20. This is to prevent adhesiveness between the coating layer 40 and the core yarn 20 from being deteriorated due to use of different materials.

FIG. 2 illustrates a structure of an extruder 50 for extruding the yarn 10 containing the functional powder of FIG. 1.

The extruder 50 includes an inner tube 60, and an outer tube 70 fitted on a circumference surface of the inner tube 60, and is preferably constructed to form a space part 80 as much as a predetermined size between the inner tube 60 and the outer tube 70.

In the above constructed extruder 50, the polyester 20a of a gel state mixed with the Tourmaline powder 30 and being the material of the core yarn 20 is inputted into and extruded from the inner tube 60 at a high pressure. A coating liquid 40a being a raw material of the coating layer 40 coated on the outer diameter of the core yarn 20 is inputted at a high pressure into the space part 80 provided between the inner and outer diameters 60 and 70, and then is coated on the outer diameter of the polyester 20a under extrusion. As a result, as shown in FIG. 1, the yarn 10 having the coating layer 40 formed on the outer diameter of the core yarn 20 mixed with the Tourmaline powder 30 is manufactured. Hereinafter, a method for manufacturing the yarn 10 containing the Tourmaline powder using the extruder 50 will be described in detail.

First, the polyester 20a being the raw material of the core yarn 20 is melted to be in the gel state at a predetermined temperature.

After that, the Tourmaline powder 30 pulverized to have a predetermined size, preferably, a size of 0.05 μm to 0.15 μm using a pulverizing device is mixed and uniformly agitated with the melted polyester 20a, and then is manufactured in a chip form. The Tourmaline powder 30 preferably employs a powder made in Brazil emitting anions of about 400 to 2000 in number.

In a melted state of a mixture manufactured in the chip form, that is, the polyester 20a mixed with the Tourmaline powder 30, the polyester 20a passes (is extruded) into the inner tube 60 of the extruder 50 and at the same time, the coating liquid 40a being the raw material of the coating layer 40 is inputted into the space part 80 provided between the inner and outer diameters 60 and 70 of the extruder 50. After that, the polyester 20a mixed with the Tourmaline powder 30 passing through the inner tube 60 is extruded and formed as the core yarn 20, and the coating liquid 40a inputted into the space part 80 between the inner and outer tubes 60 and 70 of the extruder 50 is coated on the outer diameter of the formed core yarn 20, thereby forming the coating layer 40 on the outer diameter of the core yarn 20.

Next, the core yarn 20 having the coating layer 40 is dried for a predetermined time and, if so, the yarn 20 containing the Tourmaline powder is manufactured as shown in FIG. 1.

FIG. 3 illustrates woven fabrics 100 obtained from the yarn of FIG. 1, and FIG. 4 illustrates clothes 200 being textile articles obtained from the fabrics 100 of FIG. 3.

As shown in FIGS. 3 and 4, the clothes 200 obtained from the woven fabrics 100 that is obtained from the yarn 10 containing the Tourmaline powder can have the functionality such as deodorization, anti-bacteria, and dehumidification and in addition, can show various effects of the Tourmaline powder 30.

Meantime, the present invention typically provides a description in which the woven fabrics 100 obtained from the yarn 10 containing the Tourmaline powder is associated with the clothes, but in addition to the clothes, the inventive fabrics can be associated with and used for even other all textile articles (for example, sheet, cushion or pillow).

FIG. 5 illustrates a yarn containing a Monazite powder being a functional powder according to the second embodiment of the present invention. As shown in FIG. 5, the yarn 310 containing the Monazite powder has the same construction as the yarn 10 according to the first embodiment of the present invention, that is, the yarn 310 includes a core yarn 320 formed by melting and extruding polyester being a synthetic resin, and a coating layer 340 that is of the same material as the core yarn 320 and coated on an outer diameter of the core yarn 320. The yarn 310 is characterized by mixing the Monazite powder 330, instead of the Tourmaline powder, with the core yarn 320. Meantime, the yarn 310 containing the Monazite powder is manufactured in the same method as the manufacture method of the first embodiment of the present invention. The woven fabrics of FIG. 3 of the first embodiment are obtained from the above manufactured yarn 310, and the clothes of FIG. 4 of the first embodiment are obtained from the woven fabrics.
