The present invention provides a method for producing a polyamide crimped yarn for antimicrobial carpet, more specifically, an antimicrobial agent is given to the yarn by spinning and spinning an inorganic antimicrobial agent with a polyamide polymer during melt spinning of polyamide. The present invention relates to a method of manufacturing BFC (Bulkized Continuous Filament) for sanitary carpet.

Recently, as the interest in the environment increases, sanitary processing is often applied to household goods. Especially, the carpet, which is closely related to our life due to the nature of its use, is easily contaminated with microorganisms and is difficult to wash. In addition to various textile products, sanitary processing efforts by various antimicrobial agents are actively underway.

In general, the method for imparting antimicrobial properties to carpets is similar to that for general textile products. For example, organic silicone quaternary ammonium salts, natural polymer materials, chitosan, etc. are mainly used.

Japanese Patent Laid-Open Nos. 62-299578, 4-308246, and 3-234877 employ a method of coating a resin containing such an antimicrobial agent on a fabric, but such a method is finally manufactured. Its texture is stiff and its texture is poor, which is a problem in use.In Korean Patent Publications 96-13469 and 96-13195, antibacterial emulsions are mixed with a binder to pad and dry the antimicrobial emulsion solution on the surface of the product in post-processing. The treatment method in the post process has a disadvantage in that the drug is not uniformly distributed on the product surface as a whole, the spray nozzle is blocked when the drug viscosity is high, and the drug is lost during washing, and the antimicrobial effect decreases with time.

Therefore, the present inventors made a careful study focusing on the fact that the antimicrobial properties of the yarns in the BCF manufacturing process, which is a carpet yarn, can solve the above problems and expect cost-saving effects by simplifying the process. As a result, the present invention was reached.

The present invention relates to a method for producing an antimicrobial carpet by spinning an inorganic antimicrobial agent during spinning of polyamide to produce an antimicrobial carpet, and using this yarn.

More specifically, the content of the drug in the total weight is 0.2 to 2.0 weight by uniformly mixing the nylon 6 polymer having a sulfuric acid relative viscosity (RV) of 2.5 to 2.8 and the nylon 6 polymer having an antibacterial zeolite content of 15 to 30% by weight. Melt spinning through spinneret to reach% level, stretch between 2.5 and 3.5 times between Gododetro 1 and Gododetrol 2, and then texturize and cool to 180-230 ℃ to give bulkiness. It was manufactured by the process of winding up in a winder via the rotary roll guide, the Godo controller 3, and the interlace nozzle.

In general, BCF yarns radiate at a high temperature of 250 ° C or higher, so they require the use of antimicrobial agents that do not lose their antimicrobial effects even at high temperatures. Should be used.

In the present invention, BCF yarns were prepared by spinning a natural zeolite in an inorganic antimicrobial agent and selecting a drug exhibiting antimicrobial properties by substituting metal ions such as silver (Ag), tin (Zn), and copper (Cu).

At this time, the important thing is the size of the antimicrobial drug and the drug content in the yarn, the size of the drug is less than 3㎛, the drug content is preferably 0.2 to 2.0% by weight or less to the total weight. If the size is 3 μm or more, or the chemical content is more than 2.0 wt%, the spinning workability is poor and the pressure of the spinning pack rises sharply, and the replacement cycle of the spinning nozzle is shortened, causing problems in the spinning process. .

When the carpet is produced by the nylon 6 crimping yarn having the antimicrobial prepared according to the present invention it is possible to produce an antimicrobial carpet excellent in antimicrobial and washing resistance.

Hereinafter, the present invention will be described in detail with reference to Examples and Comparative Examples, but the scope of the present invention is not limited by the following Examples.

Example 1

Nylon 6 polymer having a sulfuric acid relative viscosity (RV) of 2.70 and a nylon 6 polymer containing 20% by weight of an antimicrobial zeolite agent substituted with about 10 to 15% by weight of tin (Zn) ion and about 100 to 200 ppm of silver (Ag) ion in natural zeolite. After mixing, the drug content is 0.2% by weight at the total weight and extruded through a three-lobed release nozzle with a discharge amount of 252g / min at a spinning temperature of 250 ° C, and then 18 ° C · 0.4m / min past the hood directly under the nozzle. After cooling in the quenching part having wind speed, the film was stretched at a draw ratio of 3.0 in the Godetrol 1 and the Godetrol 2 to form a crimp at a hot air of 250 ° C., followed by wine production to produce carpets.
