Abstract
Description
- The present invention relates to a spandex having deodorant properties and a method for preparing the same, and more particularly, to a deodorant spandex having improved processability and enhanced deodorant performance through improved dispersibility of a deodorant, and a method for preparing the same.
- Polyurethane elastic yarn has excellent elasticity and elastic recoverability, and is widely used for stockings or women's underclothes and elastic fabrics, with continued expansion of its use for aerobics and swimwear.
- However, due to degradation products of sweat, sebum and fatty acids discharged from the body, unpleasant odors such as ammonia, acetic acid, isovaleric acid, nonenal, and the like are produced.
- In addition, instances may occur where many types of bacteria and fungi attach to and grow on clothing due to various secretions discharged from the body. In general, Staphylococcus aureus or uremic bacteria which reproduce using sweat and waste materials secreted from the human body as nutrient sources, are not only harmful to the human body by causing skin disease in sensitive parts of the skin, but also excretion of harmful bacteria take part in the degradation action to generate ammonia gas which produces malodor, causing a problem of embrittlement or discoloration of the textile and fabric materials.
- In order to solve these problems, deodorant performance has been developed by applying an inorganic deodorant. However, since the inorganic deodorant has poor dispersibility, it causes agglomeration phenomenon in the spandex polymer, prolongs the slurry milling process time in the preparation process of the deodorant spandex, and is limited in the applied content due to problems of nozzle clogging, shortening of the nozzle replacement cycle, and the like.
- Therefore, it is necessary to enhance dispersibility of the inorganic deodorant in the spandex polymer since the deodorant functionality varies depending on the degree of dispersion of the inorganic deodorant in the spandex polymer.

Here the composite metal oxide means that it contains two or more metals selected from Zn, Si, Mg, or Al, or at least two or more metals including one metal selected from Zn, Si, Mg, or Al and other metals.
- For the other metals Cu, Ni or Fe may be used.
- To provide detailed examples of the above-described metal oxide or the composite metal oxide according to the present invention, any one selected from among ZnO and SiO2 may be used. However, the present invention is not limited thereto.
- For the wet dispersant, DISPERBYK can be used, for example any one selected from DISPERBYK-110, 111, 162, 164, 168, 180 or 185, but the present invention is not limited thereto.
- In addition, in a conventional method of preparing spandex, the present invention provides a method for preparing a deodorant spandex comprising the steps of: adding 1.0-10 wt % of an inorganic deodorant with respect to the solid content of the polymer for preparing a spandex including at least any one selected from a metal phosphate containing Zr or a metal oxide or a composite metal oxide selected from at least one or more of Zn, Si, Mg or Al, adding 1 to 17 wt %, of a wet dispersant with respect to the inorganic deodorant; adding other additives including at least one of an antioxidant, a yellowing inhibitor, a quencher, an anti-adhesive agent, a function-improving agent, or dye enhancer, and characterized by being added to the spandex polymer in slurry form through a milling process.
- The present invention is added to the spandex polymer in slurry form through the milling process in order to improve the dispersibility of the inorganic deodorant, and can be prepared through two methods: the inorganic deodorant, the wet dispersant, and other additives may be all mixed together and prepared in slurry form, then added to the spandex polymer; or other additives are prepared in slurry form and added to the spandex polymer first, then the inorganic deodorant and the wet dispersant are mixed and prepared in slurry form and added to the spandex polymer which has the other additives in the slurry form added thereto.
- The inorganic deodorant may be added in an amount of 1.0 to 10 wt % with respect to the solid content of the deodorant spandex yarn. If the amount is less than 1.0 wt % the deodorant performance does not pass the acceptance standard, and if it is applied in an amount exceeding 10 wt % further effect may not take place due to the critical value of the deodorant effect.
- The wet dispersant may be added in an amount of 1 to 17 wt % with respect to the inorganic deodorant. If the amount is less than 1 wt % dispersibility is not improved, and even when it exceeds 17 wt % no further improvement is shown.
- In the present invention, in order to prevent discoloration and deterioration of physical properties of polyurethane-urea resulting from heat treatment, and the like accompanying ultraviolet rays, atmospheric smog and spandex processing, other additives such as conventional antioxidants, yellowing inhibitors, chlorine removers, quenchers, anti-adhesive agents, function-improving agents, and dye enhancers may be suitably combined and added to the polymer.
- Hereinafter, the present invention will be described in detail with reference to examples and comparative examples.
- A slurry was prepared by milling 1.0 wt % of an antioxidant, 0.3 wt % of a yellowing inhibitor, 0.5 wt % of an anti-adhesive agent, 0.4 wt % of a dye enhancer and 0.2 wt % of a function-improving agent using a grinder-mill and added to a conventional spandex polymer to prepare a buffer polymer. 3.0 wt % of a deodorant having Zr-phosphate compound with respect to the solid content of spandex polymer was mixed with 5 wt % BYK DISPERBYK-168 as a dispersant with respect to the deodorant, and milled using the grinder-mill to prepare a slurry, then added to the buffer polymer to prepare a spinning stock solution. The spinning stock solution was used to prepare a 20 denier fiber in a dry spinning process.
- 3.0 wt % of a deodorant having Zr-phosphate compound with respect to the spandex polymer, 5 wt % BYK DISPERBYK-168 as a dispersant with respect to the deodorant, 1.0 wt % of an antioxidant, 0.3 wt % of a yellowing inhibitor, 0.5 wt % of an anti-adhesive agent, 0.4 wt % of a dye enhancer, and 0.2 wt % of a function-improving agent were mixed and milled using a grinder-mill to prepare a slurry, then the slurry was added to the spandex polymer and mixed to prepare a spinning stock solution. The spinning stock solution was used to prepare a 20 denier fiber in a dry spinning process.
- The procedure was carried out in the same manner as described in Example 1, except that the dispersant was applied in an amount of 10 wt % with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 1, except that the dispersant was applied in an amount of 15 wt % with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 1, except that the deodorant was added in an amount of 4.5 wt % with respect to the spandex polymer.
- The procedure was carried out in the same manner as described in Example 5, except that the dispersant was applied in an amount of 10 wt % with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 5, except that the dispersant was applied in an amount of 15 wt % with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 1, except that the dispersant was applied in an amount of 17 wt % with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 6, except that the dispersant was applied in an amount of 17 wt % with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 1, except that a spandex spinning stock solution was prepared without adding the slurry prepared using the dispersant and deodorant.
- The procedure was carried out in the same manner as described in Example 1, except that a spandex spinning stock solution was prepared by adding and mixing a slurry prepared by adding only the deodorant and not the dispersant.
- The procedure was carried out in the same manner as described in Example 1, except that a spandex spinning stock solution was prepared by adding and mixing a slurry prepared by adding 0.5 wt % of the dispersant with respect to the deodorant.
- The procedure was carried out in the same manner as described in Example 1, except that 4.5 wt % of the deodorant was applied without adding the dispersant.
- The spandex prepared according to the Examples and the Comparative Examples were evaluated for the deodorant properties and dispersibility using the following methods. The results are shown in Table 1.
- Evaluation Method of Ammonia Deodorant Properties
- The ammonia deodorant properties was evaluated by measuring according to ISO 17299-2 of the detector tube method.
- 1 g of the spandex yarn sample was placed in a 3 L Tedlar bag, then ammonia gas at a concentration of 100 ppm was added thereto. After 2 hours, the residual concentration was measured with a detector tube and calculated as a reduction rate (%).
-
Deodorization Rate (%)=(B−A)B*100% - B: Ammonia residual concentration in a blank test
- A: Ammonia residual concentration in a test sample
- Dispersibility Evaluation Method
- The slurry prepared after the slurry milling process was added to the spandex polymer solution at an application content ratio and mixed to prepare a film, then the solvent was dried and its state determined. The results are shown in Table 1. (Determined dispersion degree of the additives).
-
TABLE 1 Classification Deodorization Rate (%) Dispersibility Example 1 88.9 Δ Example 2 88.0 ∘ Example 3 97.0 ∘ Example 4 96.5 ∘ Example 5 99.0 Δ Example 6 98.5 ∘ Example 7 99.0 ∘ Example 8 97.0 ∘ Example 9 98.0 ∘ Comparative Example 1 31.0 ∘ Comparative Example 2 73.0 x Comparative Example 3 80.0 x Comparative Example 4 90.0 x ∘: Good dispersibility, Δ: Has some agglomeration phenomenon. x: Poor Dispersion (Aggregated) - As shown in Comparative Example 3 of Table 1, dispersibility was poor when dispersant was added in an amount of 0.5 wt %, which is less than 1 wt %, with respect to the deodorant.
- In addition, even when the dispersant was added in an amount exceeding 15 wt % with respect to the deodorant as in Examples 8 and 9, it was found that the deodorization rate and dispersibility measured were similar to that of Example 7 in which 15 wt % of the dispersant was added.
- The dispersibility of the inorganic deodorant in the spandex polymer of the present invention is also shown in
FIG. 1 . It is a film image of the buffer polymer prepared in Example 1. Almost no deodorant shown as white spots is observed, therefore it can be confirmed that dispersibility of the inorganic deodorant in the spandex polymer is very favorable. - In contrast,
FIG. 2 shows a film image of the buffer polymer prepared in Comparative Example 2 with no dispersant added. A great amount of white spots are observed, and many of the inorganic deodorant in the spandex polymer are aggregated. Therefore, it can be confirmed that dispersibility of the inorganic deodorant in the spandex polymer is poor. - Similarly, in
FIG. 3 showing a film image of the buffer polymer prepared in Comparative Example 3 with the dispersant added in an amount of less than 1 wt %, many white spots were observed. Therefore, it can be confirmed that dispersibility of the inorganic deodorant in the spandex polymer is poor. - The present invention was described above with reference to the examples, but it will be understood that a person skilled in the art can make various modifications and variations to the present invention without departing from the technical idea of the present invention as defined in the appended claims.
