Problems solved by technology

[0008] In addition, besides jade, it also introduced the production of negative ion chips by crushing morganite, tourmaline, titanium, and medical stone, and mixing them with cotton yarn, polyester, nylon, acrylic, polypropylene, etc. to produce raw silk that radiates negative ions and far-infrared rays. technology (Korean Laid-Open Patent Publication No. 10-2009-0093507) and the technology of spinning and preparing jade silk by mixing finely pulverized jade powder with spinning raw materials (Korean Laid-Open Patent Publication No. 10-2000-0065341), but it is difficult Confirm the specific preparation process, far-infrared effect, and durability of raw silk
[0009] Moreover, the disadvantages of the prior art are as follows, that is, since the jade powder is attached to the surface of the fiber by a binder, it is difficult to apply it evenly, and it falls off due to washing, etc., resulting in the loss of the far-infrared function.

[0026] Preparation of jade powder

[0027] Although nephrite, jadeite, and serpentine can all be used, the jade used in the embodiment of the present invention is Chunchuan jade in nephrite. By pulverizing the raw Chunchuan jade stone, a uniform fine powder of 0.5 to 1 μm is achieved. The size of jade powder is determined by the thickness of the raw silk. If the raw silk is thicker, you can use a larger powder. However, considering the strength of the final drawn yarn, far-infrared radiation rate, spinnability, etc., an appropriate particle size is specified. Very important. The present invention prepares jade-containing stretched yarns with a denier of 40-85 and a filament count of 36-204 through final stretching, and it is confirmed that the particle size of the jade powder cannot exceed 1 μm.

[0028] Powder size and spinnability

[0029] (1) The size of jade powder is 500~700nm

[0030] It is easy to spin because the powder is well dispersed in the original yarn, which...

[0050] Preparation of masterbatch

[0051] By mixing 20% ​​by weight of jade powder, which is completely dried and dehydrated under vacuum, to 80% by weight of polyester chips and put into the initial interval, intermediate interval, and final interval to maintain the temperature of 250°C, 260°C, and 270°C respectively screw extrusion machine. Resin that becomes liquid in a high temperature state is drawn out through a nozzle, cooled, and continuously cut into a predetermined length of 2×3 mm to prepare a masterbatch.

[0052] melt spinning

[0053] A 75-denier, 36-filament drawn yarn (DTY) was prepared by mixing 7% by weight of the masterbatch prepared and dried in the above-mentioned steps with 93% by weight of the polyester raw material and performing melt spinning, false twisting and drawing. As a result of observing the surface and section of the actual raw silk through a microscope, it was confirmed that Chunchuan jade powder was located on the surface and inside of th...

Abstract

A method for manufacturing a jade fiber is disclosed. A master batch is manufactured using uniform jade powder of 0.5-1 mum, and the master batch and polyester raw materials are mixed in a stabilizedmixing ratio and spun in a specific thickness range so as not to significantly impair the spinning performance. The present invention also provides a method for providing a functional jade fiber whichhas an excellent far-infrared radiation effect in the manufactured fiber and has excellent durability of the fiber.

Description

technical field [0001] The present invention relates to the preparation method of the raw silk that contains jade powder and the bedding fabric that utilizes prepared raw silk, more specifically, relate to prepare masterbatch with fine jade powder and have the macromolecular resin ( Polyester) raw materials are mixed and spun to prepare precursors with far-infrared radiation function, and the fabric prepared from the precursors is used in bedding. [0002] In particular, the size of the stabilized jade powder to be mixed before spinning, the content of the jade powder contained in the masterbatch, the content of the masterbatch mixed with the spinning resin, and the condition of the fineness of the final yarn produced are among the characteristics point. Background technique [0003] Jade, germanium, tourmaline and other ores are natural minerals with excellent far-infrared radiation. Among them, jade is a mineral familiar to people who have been used as decorations since a...
