Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a deodorizing spandex,

More particularly, the present invention relates to a deodorant spandex capable of simultaneously removing various odor components and a method for producing the same.

Polyurethane elastic yarn is excellent in elasticity and resilience, and is widely used for stockings, women's underwear, and stretchable fabrics, and has been widely used for aerobics and swimwear.

However, due to decomposition products of sweat, sebum and fatty acid discharged from the body, an unpleasant odor such as ammonia, acetic acid, isovaleric acid, nonenal, and the like is produced.

In addition, many kinds of fungi and fungi attach to the clothing due to various secretions discharged from the body. In general, Staphylococcus aureus or uremic bacteria which reproduce by sweat and waste materials secreted from the human body as a nutrient source It is not only harmful to the human body such as causing skin disease in a sensitive part of the skin, but also excretion of harmful bacteria participates in the decomposition action to generate ammonia gas to give offensive odor, causing a problem of embrittlement or discoloration of the fiber and textile material come.

In particular, there is a demand for a deodorizing function for nonenal which causes an odor of aging, which is a unique body odor produced by acetic acid, isovaleric acid and middle-aged people causing ammonia, acetic acid and foot odor causing sweat odor.

Japanese Unexamined Patent Publication No. 2006-28453 discloses a polyurethane elastic body having excellent antibacterial and odor-removing properties and excellent discoloration resistance, and a polyurethane elastic fiber composed of the polyurethane elastic body Lt; / RTI >

Japanese Laid-Open Patent Publication No. 2012-127015 discloses a polyurethane elastic yarn having excellent deodorizing and antimicrobial properties even after washing, and a production method thereof.

However, all of the above-mentioned patents relate to polyurethane elastic fibers or elastic yarns excellent in antibacterial and deodorant properties including an inorganic deodorant, but only some odors can be removed in deodorization.

Therefore, it is necessary to apply a deodorant to develop spandex fibers which can effectively remove the four odors of ammonia, acetic acid, isovaleric acid and nonane.

It is also necessary to improve the dispersibility in the polymer and improve the effect thereof.

The deodorant spandex of the present invention can produce a deodorant spandex excellent in four odor removal rates such as ammonia, acetic acid, isovaleric acid and nonane.

The present invention will be described in detail below, and the following embodiments are for illustrative purposes only and the present invention is not necessarily limited thereto.

The present invention provides a deodorant spandex comprising at least two kinds of inorganic deodorants among A, B and C below.

A. Inorganic deodorant consisting of metal phosphate including Zr

B. Inorganic deodorant containing at least one element of Zn, Si or Al

C. Organic amine-based deodorant containing Mg or Al element

The present invention also relates to a method for producing spandex comprising the steps of adding at least two kinds of inorganic deodorants out of the A, B and C inorganic deodorants to the polymer for producing spandex, , And a step of preparing a polymerized product by adding at least two kinds of inorganic deodorants out of the C inorganic deodorant.

The deodorizing spandex according to the present invention may include two kinds of inorganic deodorants among the A, B and C inorganic deodorants, for example, A and C, or B and C, or a combination of A, B and C However, the present invention is not limited to the above examples.

Of the inorganic deodorant A, it may be used an inorganic deodorant composed of metal phosphate containing Zr, for example _{Zr (HPO 4) 2, ZrP} 2 O 7, (ZrO) 2 P 2 O 7 or ZrO (H ₂ PO ₄ ) ₂ can be used.

Among the inorganic deodorants, B may be an inorganic deodorant containing at least one element selected from the group consisting of Zn, Si, Mg, Cu, Ni, Fe and Al. For example, Zn, Si, Mg, Cu, , A metal oxide or a composite metal oxide containing at least one kind of element selected from the group consisting of a metal oxide and a metal oxide, or a mixture thereof.

The composite metal oxide refers to an oxide containing at least two metals selected from Zn, Si, Mg, Cu, Ni, Fe, and Al.

Specifically, B is, for example, SiO ₂ , ZnO, Al ₂ O ₃ or Fe ₂ S ₂ But B of the present invention is not limited to the above examples.

Among the inorganic deodorants, C may be an organic amine-based deodorant containing at least one element selected from the group consisting of Mg, Al, and Si, and may be a metal oxide and / or a composite metal oxide containing at least one element selected from Mg, For example, MgO, SiO ₂ , Al ₂ O ₃ , and the metal oxide and / or the composite metal oxide may include, for example, R'-NH ₂ which is an organic amine group. Oxides and / or complex metal oxides are not limited to the above examples.

Although there is no limitation on the type of R 'in the organic amine group R'-NH ₂ , in the present invention, alkyl groups such as CH ₃ -, CH ₃ CH ₂ and CH ₃ CH ₂ CH ₂ - have.

The inorganic deodorants A and B are excellent in the ability to remove ammonia, acetic acid, and isovaleric acid, which are major components of sweat odor, and deodorant C is excellent in the ability to remove acetic acid, isovaleric acid and nonane.

However, the inorganic deodorant is not limited to the effect of removing each odor component, and the deodorizing effect may be different depending on the application of each.

Thus, the present invention can provide a deodorizing agent capable of removing odor components such as ammonia, acetic acid, isovaleric acid or nonenal, which is a component that induces odors, including at least two kinds of inorganic deodorants out of the A, B, Provides spandex.

In particular, at least two kinds of inorganic deodorants among the A, B, and C inorganic deodorants are added in an amount of 0.3 to 5 wt%, respectively, relative to the solid content of the spandex polymerizate, and ammonia and acetic acid in the odor- 70% or more, isovaleric acid can provide a deodorant spandex having a capability of removing more than 75% of odor components based on the weight of 0.5 g of spandex yarn and 85% or more based on the weight of 0.5 g of spandex yarn, .

If at least two kinds of inorganic deodorants among the A, B, and C inorganic deodorants are added in an amount of less than 0.3 wt% with respect to the solid content of the spandex polymerizate, the deodorizing effect does not pass the acceptance standard. No further effect may be shown. Also, since the inorganic deodorant is added in an excess amount, the physical properties of the yarn may be deteriorated, so that the application of the raw yarn may be difficult, and the process of dispersing the inorganic deodorant may be prolonged in preparation of the spinning solution.

Hereinafter, the present invention will be described in detail with reference to examples and comparative examples.
