The present invention provides a polyvinyl chloride (PVC) paste backed carpet with antibacterial and antifungal bioactivity. BACKGROUND ART Conventionally, carpet mats have been installed at entrances and the like to prevent dust attached to the soles of shoes from entering indoor spaces. This pine is
A paste made from vinyl chloride resin and a relatively large amount of plasticizer is molded as the lining layer of the mat, and the fiber layer on the surface of the mat will absorb dust adhering to the soles of shoes, etc. That is. However, since conventional pine trees were not treated with any antibacterial treatment, bacteria attached to the dust adsorbed to the pine trees grew inside the pine trees, and when pedestrians stepped on the pine trees, they were brought indoors and became unsanitary. Ta. The present invention has a structure that effectively suppresses the generation of microorganisms such as bacteria and mold in a carpet, and in a method for manufacturing a carpet consisting of a polyvinyl chloride backing layer and a surface fiber layer, the carpet backing layer has a decomposition temperature of 160°C. Form an uncured PVC paste layer containing a polycyclic nitrogen-containing compound or silicon quaternary ammonium salt-based drug with biological activity above ℃, and then heat the paste layer to a temperature below the decomposition temperature of the drug. The gist of the invention is a method for producing a biologically active carpet, which is characterized in that it is heated to gelatinize the carpet. The fiber surface layer is made of animal hair, nylon, polyester,
Fabrics such as needle punch, woven pile, tufted cut pile, and loop pile can be used with fibers such as acrylic. It is preferable that the fiber layer be subjected to some kind of antibacterial treatment. The PVC backing layer used in the present invention is applied in the form of a PVC paste, and as the PVC resin, in addition to so-called straight polymers, copolymer resins with vinyl acetate, acrylic monomers, butadiene, etc. can also be used. The resin may be a paste resin obtained by emulsion polymerization alone, or may be a combination of this paste resin and a suspension-mixed resin. 40 to 200 parts by weight, especially 50 to 15 parts by weight of plasticizer are applied per 100 parts by weight of vinyl chloride resin.
Examples of plasticizers include well-known plasticizers for PVC resins, such as phthalate esters such as dioctyl phthalate and dibutyl phthalate; polyester plasticizers such as polyadipate and polysepartate;
Epoxy plasticizers and the like may be used alone or in combination of two or more. The paste composition for the backing layer can contain compounding agents known per se according to known formulations, such as heat stabilizers such as organotin-based and metal soap-based ones, Examples include lubricants, fluidity improvers, colorants, fillers, reinforcing agents, and ultraviolet absorbers. The present invention further includes a bioactive agent having a decomposition temperature of 160° C. or higher mixed in the PVC paste backing layer. Biologically active agents are agents that have bactericidal and antifungal properties.Containing these agents in the lining layer prevents the infiltration of bacteria and mold indoors, and prevents the infiltration of bacteria and mold indoors or inside buildings. is kept in a clean and desirable condition. In the carpet manufacturing method of the present invention, the PVC paste to which the drug has been added is heated and gelled at 150 to 250°C, and the above-mentioned biologically active drug is
Heat resistance with a decomposition temperature of 160℃ or higher is required,
Silicon quaternary ammonium salt type (decomposition temperature 180
(℃), polycyclic nitrogen-containing compounds (decomposition temperature: 250℃), etc. are used. Of course, one or more of the above drugs may be used in combination. These chemicals are 0.5 to 5% by weight based on PVC resin.
added. Note that the drug may be added directly into the PVC paste. The above drug has a decomposition temperature of 160
℃ or above and below the decomposition temperature of this drug
The paste layer is heated to gel and form the carpet backing material. For the first time, the manufacturing method of this invention most effectively and sustainably eliminates bacteria in PVC paste-backed carpets that require high-temperature treatment steps during the manufacturing process.
It has a biologically active effect that kills mold and improves the cleanliness of rooms or buildings. The carpet of the present invention is pine-shaped and can be used in the restaurant industry, inns, etc.
It can also be used at the entrances of hospitals, food factories, etc., elevator halls, etc., but it is even more effective if it is laid out in the form of carpet tiles. Examples 1 to 3 On the back side of the nylon cut pile tufted fabric, 1% of the biologically active agent of a polycyclic nitrogen-containing compound (manufactured by trade name 3539H, decomposition temperature 250°C, manufactured by Osaka Kasei) was applied to the PVC. , 2%, and 3% (weight percent) were applied and heated to gel at 200° C. to obtain a PVC-lined carpet. The resulting carpet was infected with Staphylococcus aureus and
A halo test for mold resistance was conducted according to JIS Z 2911. PVC paste resin 70 parts PVC blend resin 30 parts Plasticizer (DOP) 90 parts Calcium carbonate 100 parts Stabilizer 2 parts Pigment 1 part Example 4 Silicon quaternary ammonium salt-based silicon quaternary ammonium salt with a decomposition temperature of 180°C is added to the PVC paste. A biologically active drug (Biosil x manufactured by Dow Corning, USA) is coated with PVC.
It was applied on the same fabric as in Example 1 and gelled at 160°C to obtain a PVC-lined nylon cut pile carpet. The same experiment as in Example 1 was conducted using the obtained carpet. The results are shown in Table 1. Comparative Example 1 The same PVC-lined nylon carpet as in Example 1 was prepared, except that no biologically active drug was contained in the PVC backing material, and the same experiment as in Example 1 was conducted.

[Table] The values in Table 1 are the longest circular length of the halo x
Indicates the shortest mm. The numbers in [ ] indicate the series of mold generation states. For [1], mold adhesion is observed on more than 1/3 of the specimen surface. [2] shows mold adhesion on less than 1/3 of the specimen surface. [3] shows no mold adhesion on the specimen surface. In addition, in Comparative Example 1, the mold adhesion percentage after 14 days was 90%.
It was hot. From the above results, Examples 1 to 4 all showed effective biological activity against Staphylococcus aureus and mold, and in particular, Examples 1 to 3 consistently showed grade 3 in the mold resistance test, indicating excellent Antifungal properties were obtained. Comparative Example 2 A PVC-lined carpet similar to that in Example 1 was obtained except that the same amount of Sanitized PDX (acid amide type, manufactured by Sanitize Company, USA) as in Example 1 was added in place of Example 1, but Staphylococcus aureus Also, no halo effect was obtained against mold and mildew. The decomposition onset temperature of sanitized PDX was below 160°C, and when it was heated above 160°C, it decomposed and its medicinal efficacy was drastically reduced. Thus, the tile carpet of Comparative Example 2 did not exhibit any biological activity.
