Definitions
- 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.
- 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.
- deodorant performance has been developed by applying an inorganic deodorant.
- the inorganic deodorant 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.
- the present invention aims to solve the above-described problems of the prior art by providing a deodorant spandex having more enhanced deodorant performance and improved processability, by using a dispersant together when applying an inorganic deodorant to improve dispersibility of the deodorant, and a method for preparing the same.
- the present invention provides a deodorant spandex prepared by comprising an inorganic deodorant, including at least any one selected from metal phosphate containing Zr or metal oxide or composite metal oxide selected from Zn, Si, Mg or Al, and a wet dispersant.
- the present invention provides a method for preparing 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 Zn, Si, Mg or Al; adding 1 to 17 wt % of a wet dispersant with respect to the inorganic deodorant; and characterized by being added to the spandex polymer in slurry form through a milling process.
- the deodorant spandex of the present invention uses the wet dispersant together with the inorganic deodorant, thereby improving the agglomeration phenomenon, thus enhancing the process and improving dispersibility in the spandex yarn, thus enhancing deodorant performance of the deodorant.
- FIG. 1 is a film image of a buffer polymer prepared according to Example 1.
- FIG. 2 is a film image of a buffer polymer prepared according to Comparative Example 2.
- FIG. 3 is a film image of a buffer polymer prepared according to Comparative Example 3.
- the present invention provides a deodorant spandex comprising an inorganic deodorant, including a metal phosphate containing Zr or a metal oxide or a composite metal oxide selected from Zn, Si, Mg or Al, and a wet dispersant.
- an inorganic deodorant including a metal phosphate containing Zr or a metal oxide or a composite metal oxide selected from Zn, Si, Mg or Al, and a wet dispersant.
- the inorganic deodorant that can be used in the present invention may be at least any one selected from metal phosphate containing Zr, metal oxide or composite metal oxide.
- any one selected from 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.
- the metal oxide or the composite metal oxide contains at least one element selected from Zn, Si, Al, and Mg.
- 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.
- Ni or Fe may be used.
- any one selected from among ZnO and SiO 2 may be used.
- the present invention is not limited thereto.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- ammonia deodorant properties was evaluated by measuring according to ISO 17299-2 of the detector tube method.
- Deodorization Rate (%) ( B ⁇ A ) B* 100%
- 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.
- 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.
- 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.
