Description

  The present invention relates to a fiber product composed of a melt-kneaded product of a resin composition containing parabens and a thermoplastic resin.

  In recent years, an antibacterial processed textile product made of a resin having an antibacterial function has been increasing and is widely used in general households. As an antibacterial processed fiber product, for example, a fiber product made of a resin mixed with an inorganic antibacterial agent such as a silver antibacterial agent and a zinc antibacterial agent having a high antibacterial function and high safety has been proposed (Patent Document 1). Patent Document 2).

  However, when an inorganic antibacterial agent is mixed in the resin, the antibacterial agent is an inorganic solid, and therefore dispersibility is poor in a thermoplastic organic resin. Therefore, as a conventional kneading means into the resin, when manufacturing a textile product by forming a granular antibacterial masterbatch once mixed with a high concentration of antibacterial agent in the same resin as the product material resin A method of mixing a predetermined amount of the antibacterial masterbatch in a resin material has been proposed (Patent Document 3). However, even when the antibacterial masterbatch is used, it cannot be said that the dispersibility of the inorganic antibacterial agent is sufficient, and the antibacterial property varies, and the inorganic antibacterial agent is discolored or clouded by light. However, a resin mixed with an inorganic antibacterial agent is not suitable for textile products.

  On the other hand, when the surface of the organic antibacterial agent is applied or kneaded, the antibacterial agent is easily volatilized, desorbed and separated from a substrate such as a fiber, and depending on the type of the organic antibacterial agent, a safety problem arises. For this reason, an insoluble immobilized antibacterial agent in which an organic antibacterial agent is bound to a polymer material with an ionic bond or a covalent bond and does not exhibit toxicity has been proposed (Patent Document 4, Patent Document 5, Patent Document 6). However, in this method, it is necessary to immobilize a quaternary ammonium base or phosphonium base ionically bonded to an acidic group such as a carboxylic acid group or a sulfonic acid group, and the resin does not have a functional group such as polyolefin. It was difficult to fix the antibacterial agent.

  Therefore, there has been a demand for a fiber product that has no restriction on the resin that can be used, is excellent in safety and antibacterial properties, and has an antibacterial agent uniformly dispersed therein.

JP 05-059662 A JP 09-328402 A JP2013-142215A Japanese Patent Laid-Open No. 54-086584 Japanese Patent Laid-Open No. 04-266912 JP 05-310820 A

  An object of the present invention is to provide a textile product that is excellent in safety and antibacterial properties and in which an antibacterial agent is uniformly dispersed.

One or more selected from the group consisting of hexyl and benzyl 4-hydroxybenzoate can be mentioned, and butyl 4-hydroxybenzoate and hexyl 4-hydroxybenzoate are preferred because they have high antibacterial properties and are hardly sublimable.

  It is preferable that the resin composition in this invention contains 1-30 mass parts of compounds represented by Formula (1) with respect to 100 mass parts of thermoplastic resins (A), and contains 3-20 mass parts. More preferably, it is more preferably 5 to 15 parts by mass.

  The method for obtaining the compound represented by the formula (1) is not particularly limited, but may be a commercially available one, or 4-hydroxybenzoic acid and an aliphatic alcohol having 1 to 10 carbon atoms in the presence of a catalyst. You may use what was obtained by reaction with aryl alcohol.

  When the content of the compound represented by the formula (1) in the resin composition in the present invention is less than 1 part by mass with respect to 100 parts by mass of the thermoplastic resin (A), as a master batch of the resin composition When the compound represented by the formula (1) is more than 30 parts by mass with respect to 100 parts by mass of the thermoplastic resin (A), the compound represented by the formula (1) is a fiber. There is a risk of aggregation or precipitation in the product.

  The resin composition in the present invention can be produced by mixing the thermoplastic resin (A) and the compound represented by the formula (1). The mixing may be performed by melt-mixing the thermoplastic resin and the compound represented by formula (1), and the resin melted by heating in a state where the compound represented by formula (1) is dissolved in a solvent.

  The heating conditions vary depending on the thermoplastic resin (A) and the compound represented by the formula (1), the type and amount of additives, or the conditions of the mixer to be used. It is desirable to heat for 1 to 600 seconds at a temperature not lower than the crystal melting temperature of the thermoplastic resin used and lower than the deterioration temperature.

  In the case where the compound represented by the formula (1) is dissolved in a solvent and mixed with the heat-melted resin, the solvent is particularly limited as long as it dissolves the compound represented by the formula (1).

The compound represented by the formula (1) in the thermoplastic resin is preferably dispersed as particles having a particle size of 2.5 μm or less in the thermoplastic resin, more preferably as particles having a particle size of 1 μm or less. More preferably, the particle is dispersed as particles having a particle diameter of 0.1 μm or less. The state of the particles can be confirmed by observing with a scanning electron microscope (SEM). The particle diameter was measured by an image analysis method for measuring the distance between two points which is the maximum dimension for one particle in a scanning electron microscope image. The particle size of the compound represented by the formula (1) in the resin composition tends to hardly change even after the production process of the fiber product. Therefore, the particle diameter of the compound represented by the formula (1) in the resin composition and the particle diameter of the compound represented by the formula (1) in the fiber product produced using the resin composition are substantially the same. It becomes.

  In the present invention, the resin composition is preferably in the form of pellets. The method for producing pellets of the resin composition in the present invention is not particularly limited. For example, the resin composition containing the compound represented by the formula (1) is molded into a sheet by extrusion molding, and this is obtained. For example, a method of cutting a sheet-like molded product into an appropriate size by a cutter or the like and processing it into a pellet can be used.

  The shape of the pellet is not particularly limited, and may be, for example, a prismatic shape or a spherical shape. As the size of the pellet, the length of the maximum side is preferably 1 to 20 mm in the case of a prismatic shape, and the particle diameter is preferably 1 to 20 mm in the case of a spherical shape.

  As a thermoplastic resin (B), the thermoplastic resin illustrated above as a thermoplastic resin (A) contained in a masterbatch is mentioned. The thermoplastic resin (B) may be the same as or different from the thermoplastic resin (A), and is preferably highly compatible with the thermoplastic resin (A) contained in the masterbatch. The same thermoplastic resin as the thermoplastic resin (A) is more preferable.

  The melt-kneaded product in the present invention preferably contains 1 to 40 parts by mass, more preferably 10 to 30 parts by mass of the resin composition, with respect to 100 parts by mass of the thermoplastic resin (B). More preferably, it is contained in parts by mass.

  Melt-kneading differs depending on the type and blending amount of the additive or the conditions of the mixer to be used. Therefore, it cannot be generally specified, but it is heated at a temperature higher than the crystal melting temperature of the thermoplastic resin used and lower than the deterioration temperature. However, it is desirable to carry out for 1 to 600 seconds.
