Problems solved by technology

However, polyester has the disadvantage of providing a hard touch due to its high Young's modulus
In addition, polyesters have little or no polar functional groups in their molecules and thus have poor hygroscopicity
Therefore, when polyester is used for clothing purposes, since it absorbs little sweat or moisture, there arises the problem that polyester provides discomfort while wearing

preparation example Construction

[0018] In order to prevent decrease in spinnability and physical properties due to decrease in viscosity during preparation of the master sheet, the viscosity of the polyester resin is preferably 0.70˜0.95 dL / g. In addition, fine zirconium phosphate inorganic particles are generally used in an amount of 1 to 20% by weight based on the solid content of yarn fibers.

[0019] In the preparation of masterbatch sheets, polyester sheets can also be used. In this case, the polyester flakes may be previously ground and then used, so that the fine inorganic particles and the resin can be easily mixed with each other. In addition, in order to improve the dispersibility of the fine zirconium phosphate inorganic particles, the fine zirconium phosphate inorganic particles and the polyester resin were mixed with each other in a rotary mixer, and introduced into a twin-screw extruder to prepare a masterbatch sheet.

[0020] The prepared masterbatch sheet is mixed with common polyester sheet...

Embodiment 1

[0025]

[0026] 2 kg of multi-layer structure fine zirconium phosphate inorganic particles having a diameter of 1.0 μm was mixed with 8 g of a polyester resin having an intrinsic viscosity of 0.8 dL / g, thereby preparing a masterbatch sheet containing 20% ​​by weight of the fine zirconium phosphate inorganic particles. In order to increase the dispersion of fine zirconium phosphate inorganic particles during preparation of the masterbatch, fine zirconium phosphate inorganic particles and polyester resin were mixed with each other in a rotary mixer and introduced into a twin-screw extruder, and a 200-mesh filter was used. The obtained masterbatch sheet was mixed with an ordinary polyester sheet so that the content of the fine zirconium phosphate inorganic particles was 0.5% by weight relative to the solid content of the yarn fibers. The mixture of the sheets is melted at a temperature of 265-270° C. to prepare a molten polymer.

[0027] The molten polymer is melt-spun through ...

Embodiment 2

[0028]

[0029] A functional yarn was prepared in the same manner as in Example 1, except that mixing was performed such that the content of the fine zirconium phosphate inorganic particles was 1% by weight relative to the solid content of the yarn fibers.

Abstract

The present invention relates to a method for manufacturing a functional yarn by using zirconium phosphate having a multilayer structure as a deodorizing material and spinning a molten polymerized material through a non-circular cross-sectional spinneret. According to the present invention, zirconium phosphate inorganic microparticles with low hardness and a layer structure are contained in the molten polymerized material, thereby minimizing the abrasion of the production process equipment, and achieving excellent deodorizing property and quick sweat absorbency, when fibers are manufactured.

Description

technical field [0001] The present invention relates to a method for producing a functional yarn having deodorizing properties as well as sweat-absorbing and quick-drying properties, in particular, to a functional yarn comprising low-hardness layered zirconium phosphate as a deodorizing material The production method of , which does not cause abrasion of production equipment in the spinning and post-processing processes, and has excellent deodorizing properties as well as excellent sweat-absorbing and quick-drying properties. Background technique [0002] Recently, with the increasing demand for high-quality life, in addition to meeting basic needs, consumers are pursuing the concept of high-function, high-emotion, comfort, aesthetics and customized fibers and clothes. Accordingly, the demand for functional fibers has increased, and the market for functional fibers has expanded. In this context, the development of fibers or fabrics with a self-deodorizing function (i.e., de...
