全面、経済面で多くの問題を未解決のまま有している。<Conventional technology> Conventional I! Thermoplastic polyesters have been widely used for general molded products such as textiles and films. Recently, there has been a rapid increase in the need for materials with antibacterial properties for use in such molded products. As a means to meet such needs, a method has generally been used in which the surface of a molded product is treated with an antibacterial agent to impart antibacterial properties. However, in this method, the antibacterial agent is first dissolved or dispersed in an organic solvent, water, etc., and then the antibacterial agent is applied, sprayed, etc., and then the solvent and dispersant are dried through a process such as evaporation. As a result, many environmental, safety, and economic problems remain unresolved.
従ってかかる問題を発しないで抗菌性を有する素材が社
会的に強く望まれて来た。Therefore, there has been a strong social desire for materials that have antibacterial properties without causing such problems.

が困難であった。On the other hand, it is also possible to consider a method of kneading an antibacterial agent into the molded product and using its oozing effect to obtain long-lasting antibacterial properties. However, a major drawback of this method is that the antibacterial agent must satisfy a number of required properties, such as being stable at the kneading temperature, not deteriorating the resin body, and not having a negative effect on subsequent processes such as stretching. However, this has been difficult with thermoplastic polyesters because of their particularly high melting points.

A polyester composition that is stable at the high melt-molding temperature of polyester such as ℃, can obtain smooth stretchability in the molding stage, and can also achieve the original purpose of achieving long-lasting antibacterial properties6. As a result of intensive research aimed at obtaining molded products, we have found that a composition in which polyester is combined with a specific antibacterial agent that has a low melting point below the glass transition point of polyester and satisfies the above properties has particularly excellent properties. They discovered this and arrived at the present invention.

が得られることが見出されたのである。In the present invention, 2,4,4'-trichloro-2'-hydroxydiphenyl ether is used as the antibacterial agent. The antibacterial agent is easily miscible with polyester, and the composition of the antibacterial agent and polyester is stable when mixed with polyester by melt molding, and since the melting point is 54 to 57°C, as mentioned above, the glass transition point of polyester is low. When it is lower, moldability such as stretchability when molding the composition is improved. Furthermore, it was discovered that since the antibacterial agent is stably contained inside the molded product, an excellent long-lasting antibacterial effect can be obtained.

It is characterized by being added to coalescence and blending. In the present invention, the melt-molding step and the steps before it mean all steps for preparing the melt before melt-molding. There are no particular limitations on the method of blending the antibacterial agent and the above-mentioned polymer in the present invention. For example, a predetermined amount of an antibacterial agent is kneaded into a molten polymer, or dried or undried polymer particles and an antibacterial agent are mixed at room temperature.
The mixture may be melt-mixed together after a drying step if necessary, or an antibacterial agent may be mixed with other additives such as polyethylene glycol, silicone oil, etc. in these steps, and the mixture may be mixed with the polymer.

。Example 1. Comparative Example 1 100 parts of well-dried polyester terephthalate (glass transition point 69°C, intrinsic viscosity 0.66 measured in orthochlorophenol at 35°C) was melted at 290°C in a nitrogen-substituted atmosphere to obtain 2,4.4' 0.1 part of -i-lichloro-2'-hydroxydiphenyl ether was added. After melt-mixing at that temperature for 7 minutes, the mixture was immediately introduced into a melt-spinning machine and spun. The obtained undrawn yarn was drawn 4 times at 85°C, passed through a hod plate at 140°C at a constant length, and wound up. The obtained yarn has a strength of 4.69/

), 10% by weight of 2.4.4'-trichloro-2'-hydroxydiphenyl ether, and 0.5% of the antioxidant Irganox 565 (trademark product) were melt-blended and heated. After mixing at this temperature for about 8 minutes,
It was immediately introduced into a melt spinning machine and spun. The obtained undrawn yarn was stretched 4 times at 80°C, passed through a hot plate at 140°C at a constant length, and wound up. The resulting yarn has a strength of 4.

- It is a novel product that contains at least a polyester composition containing hydroxydiphenyl ether, and has the characteristic that antibacterial properties are stably maintained over a long period of time. In particular, by combining the antibacterial agent with a specific polyester, stable melt molding is possible and the stretchability is good, and the antibacterial agent is stably retained in the resulting molded product. Furthermore, the molded product of the present invention combines a specific polyester with an antibacterial agent, so that the antibacterial agent is stably present inside the molded product, and its antibacterial properties are maintained for a long period of time.
