Description

  The present invention relates to a sheet, and more particularly, to a sheet having antibacterial properties and exhibiting functions such as coolness and heat retention.

  In recent years, as people's living standards have improved, awareness of health and hygiene has also increased, and textile products such as bedding and clothing such as sheets have deodorizing, antibacterial, antifungal or antifouling functions, and are refreshing. Textile products having functions such as exerting a feeling are desired.

  Textile products such as sheets manufactured in the conventional manufacturing process have insufficient antibacterial and deodorant properties, and are knitted or knitted to provide various functions such as deodorant function and antibacterial function. Anti-bacterial properties are imparted by attaching deodorant or antibacterial agent to the fiber by post-processing to carry a predetermined deodorant or antibacterial agent on a subsequent cloth or fiber product.

  In addition, blending raw materials with deodorizing and antibacterial functions into the fiber raw material for spinning synthetic fiber yarn has already been carried out, and the binder and photocatalyst agent are incorporated into the fiber structure of the curtain to provide a photocatalytic function. Patent application has already been filed for curtains which are known to have an antibacterial function and a deodorizing function (see, for example, Patent Document 1).

  In addition, an antibacterial polyester fiber containing a silver-based inorganic antibacterial agent in a polyester fiber widely used for clothing and bedding has already been filed (for example, see Patent Document 2).

  It is easy to add a predetermined function by subjecting a fiber product such as a sheet to a post-processing to add a predetermined agent after weaving and weaving. However, textile products to which a deodorant or an antibacterial agent is attached by post-processing have a problem in that a drug or the like added at the time of washing is dropped, and the service life is shortened.

  In particular, beddings such as sheets are textile products used by people every day, and therefore, it is preferable to exhibit functions such as coolness and heat retention as well as a deodorizing function and an antibacterial function.

  In addition, textile products such as fabrics that contain a photocatalyst agent exhibit a photocatalytic function and a deodorizing / antibacterial function only after being irradiated with light, so in an environment without light such as at night or in a dark room, Deodorant and antibacterial action cannot be exerted.

  Furthermore, antibacterial polyester fibers containing silver-based inorganic antibacterial agents exhibit antibacterial properties even when they are not irradiated with light, but their performance is not sufficient and it is not easy to improve antibacterial functions. .

  In view of the above problems, the present invention exhibits an antibacterial function without the need for new post-processing and with or without light. Further, in an environment with light, the present invention has further antibacterial function and deodorization. The purpose is to provide a sheet that exhibits functions, such as coolness and heat retention.

Moreover, since a refreshing feeling can be obtained, it becomes the sheet which can sleep comfortably. Furthermore, since the antibacterial agent is blended in the resin raw material in advance, the antibacterial agent is not peeled off by washing or the like, and a stable antibacterial function can be exhibited over a long period of time.

  Further, the present invention is characterized in that, in the sheet having the above-described configuration, the third yarn is a cotton / polyester blended yarn. According to this structure, the sheet which can sleep comfortably can be obtained by using the cotton blend yarn provided with a hygroscopic property and heat retention.

According to this configuration, sweat and moisture are absorbed on the fiber surface and diffused quickly, so that the material has a high heat absorption rate, and a cool refreshing feeling can be obtained.

  Further, the present invention is characterized in that, in the sheet having the above-described configuration, the synthetic yarn and cotton yarn are alternately inserted as the third yarn. According to this structure, while being able to obtain a cool refreshing feeling, moisture absorption and heat retention can be obtained.

  Further, the present invention is characterized in that, in the sheet having the above-described configuration, the third yarn is a far-infrared radiation yarn produced by melt spinning a polyester-based spinning raw material in which a far-infrared radiation material is blended in a predetermined ratio.

According to this configuration, a photocatalytic metal oxide antibacterial agent that exhibits a desired photocatalytic function can be easily obtained. Moreover, by mixing silver and silica, aggregation of silver can be prevented and uniformly dispersed in the fiber, and a predetermined antibacterial function can be exhibited.

  According to the present invention, a first yarn obtained by false twisting a yarn produced by melt spinning a polyester-based spinning raw material containing a predetermined proportion of a photocatalytic metal oxide antibacterial agent and a predetermined proportion of a silver antibacterial agent Weaving using a second yarn obtained by melt-spinning a yarn produced by melt-spinning a polyester-based spinning raw material, and a warp yarn, and a third yarn having various functions exhibiting a cool feeling and heat retention as weft Because it is a sheet, it exhibits antibacterial function regardless of the presence or absence of light without the need for new post-processing, and exhibits a refreshing feeling.In addition, in an environment with light, it exhibits a photocatalytic function, A sheet that can exhibit a more comfortable deodorant and antibacterial effect and can sleep comfortably can be obtained.

  Hereinafter, embodiments of a sheet according to the present invention will be described in detail.

  In this embodiment, in order to manufacture a sheet that exhibits an antibacterial function, the sheet is woven using yarns made of polyester fibers blended with an antibacterial agent having an antibacterial function. This is because an antibacterial function is imparted to the fiber itself that weaves the sheet by adding an antibacterial agent to the spinning raw material for spinning the polyester fiber in advance. Thus, by producing a sheet made of a woven fabric using a polyester fiber having an antibacterial function, the propagation of bacteria in the woven fabric can be suppressed, and the bed environment and the living environment can be favorably maintained.

  In the synthetic fiber production spinning process for producing polyester fiber, for example, a deodorizing and antibacterial agent is contained inside the fiber by mixing and spinning a functional imparting agent having a deodorizing function and an antibacterial function (kneading It is possible to produce polyester fiber. In this way, a synthetic fiber that exhibits a desired function can be produced by adding a colorant or various functionalizing agents to a melt-spinnable thermoplastic polymer such as polyester or polyamide.

  In addition, when melt spinning polyester fibers, a master batch is prepared in which a functional additive having a deodorizing function and an antibacterial function is previously contained in a part of the raw polymer at a high concentration. The solid content can be uniformly dispersed in the polymer by kneading into a resin, diluting to a predetermined concentration, and spinning. Furthermore, the polyester fiber which exhibits a various function can be obtained by changing the functionality imparting agent to add. In addition, the polyester fiber kneaded and melt-spun with a functionality-imparting agent naturally does not require post-processing to add functionality, and the processing steps can be shortened.

  Moreover, since the functionality-imparting agent is kneaded in the fiber in advance, the imparting agent is not peeled off by washing or the like, and a stable function can be exhibited over a long period of time. That is, the fiber product such as a sheet according to the present embodiment can exhibit a semi-permanently stable deodorant / antibacterial function.

  In this embodiment, a photocatalyst metal oxide antibacterial agent and a silver antibacterial agent are used as functional imparting agents that exhibit a deodorizing and antibacterial function, and a polyester-based spinning raw material blended in a predetermined ratio is melt-spun. Thus, an antibacterial fiber is manufactured. In addition, titanium oxide was adopted as a photocatalytic metal oxide antibacterial agent. This is because titanium oxide is a white powder and is a fine powder that is easily mixed into the raw material polymer in the melt spinning process, and is generally used as a typical material as a photocatalyst oxide and is easily available.

  As a photocatalytic metal oxide antibacterial agent, finely powdered titanium oxide is kneaded into a fiber raw material in advance and melt-spun to obtain a synthetic fiber that exhibits a photocatalytic function. Therefore, the synthetic fiber is a yarn that exhibits the photocatalytic function of titanium oxide. That is, photocatalytic functions such as a deodorizing function, antibacterial function, and antifouling function are exhibited by irradiating light.

  The kind of titanium oxide to mix | blend is not specifically limited, For example, any of an anatase type, a brookite type, a rutile type, an amorphous type etc. may be sufficient, but the anatase type titanium oxide with a high photocatalytic activity with respect to sunlight is more preferable. Moreover, the one where the particle size of the titanium oxide mix | blended with the polymer raw material for spinning is small is preferable, for example, about 0.01-2 micrometers of average particle diameters are preferable. Furthermore, it is preferable that it is the fine powder form of 0.5 micrometer or less from a viewpoint with which the specific surface area which exhibits a deodorizing function and an antibacterial function becomes large.

  When producing a fiber in which a silver antibacterial agent is kneaded, it is desirable that the solid content blended in the fiber is uniformly dispersed without agglomeration. Further, by mixing silver and silica, silver can be uniformly dispersed without agglomeration. Therefore, in this embodiment, silver and silica are mixed at a ratio of 92: 8 as the silver-based antibacterial agent. A configuration using silver silicon dioxide was adopted.

  Moreover, since silver and silica (silicon dioxide) in the form of fine powder are blended as silver antibacterial agents, they exhibit antibacterial functions regardless of the presence or absence of light. Therefore, in an environment without light, the silver antibacterial agent to be mixed exhibits an antibacterial function, and in an environment with light, the silver antibacterial agent and the photocatalytic metal oxide antibacterial agent exhibit an antibacterial function.

  In addition, the intensity of the antibacterial and deodorizing functions of the photocatalytic metal oxide antibacterial agent can be increased or decreased by increasing or decreasing the amount of light to be radiated. The brightness of the irradiated light can be improved even at night or in a closed room. The antibacterial performance can be adjusted by adjusting the thickness.

  Moreover, it is preferable that the yarn blended with the photocatalytic metal oxide antibacterial agent and the yarn blended with the silver antibacterial agent are melt-spun separately. This is because, when the respective compounding agents are mixed, it is difficult to spin fibers in which the respective compounding agents are uniformly dispersed. Moreover, as the warp used when weaving the sheets, false twisted yarn is preferable. This is because false twisting is performed, the yarn is crimped, the fibers are entangled, and yarn weaving and fiber breakage are prevented during weaving, and the touch and touch are also given. is there.

  For this purpose, a first yarn obtained by false twisting a yarn produced by melt spinning a polyester spinning raw material containing a predetermined proportion of a photocatalytic metal oxide antibacterial agent (for example, titanium oxide), a silver antibacterial agent ( For example, a sheet exhibiting a predetermined antibacterial function is woven using a second yarn obtained by false twisting a yarn produced by melt spinning a polyester-based spinning raw material containing a predetermined proportion of silicon dioxide (silver dioxide). I made it.

  Further, when the first yarn and the second yarn are used as warp yarns, the respective yarns may be arranged in order and wound around a warp beam, or two yarns may be combined in advance. It is also possible to wind a large number of these combined yarns around a warp beam, and weaving can be performed using these warp beams. Further, the first yarn and the second yarn are used as warp yarns, and a sheet is woven using a third yarn having various functions that exhibit a refreshing feeling and heat retention as a weft yarn.

  For example, as shown in FIG. 1, a sheet 1 in which wefts 3 are driven can be woven into warp yarns 2 in which first yarns 2A and second yarns 2B are alternately arranged.

  If it is this structure, the warp 2 which weaves a sheet will exhibit performance functions, such as antibacterial property, and the weft 3 will exhibit functionality, such as a refreshing feeling. In an environment where light is irradiated, a sheet exhibiting an antibacterial effect and a deodorizing effect can be obtained by a photocatalytic function. In addition, since wefts that exhibit functionality such as a refreshing feeling are used, a refreshing feeling can be obtained, and a sheet that can sleep comfortably is obtained. Furthermore, since the antibacterial agent is blended in the spinning raw material in advance, the antibacterial agent is not peeled off by washing or the like, and a stable antibacterial function can be exhibited over a long period of time.

  The third yarn to be driven in as the weft 3 is preferably a yarn having various functions that exhibit a refreshing feeling and heat retaining properties. For example, a cotton / polyester blended yarn generally used as a sheet material and a silver antibacterial agent are blended in a predetermined ratio. Polyester yarn and cotton blended yarn, synthetic yarn with hydrophilic groups, alternate weft insertion of this yarn and cotton yarn (double pick), and melting of polyester spinning raw material blended with a predetermined ratio of far-infrared radiation material A yarn far-infrared radioactive yarn produced by spinning, an alternate weft insertion (double pick) of the far-infrared radioactive yarn and cotton yarn, and the like can be used.

  If a cotton / polyester blended yarn that is generally used as a sheet is used as the third yarn, the conventional touch, moisture absorption and heat retention can be exhibited. Further, if a blended yarn of polyester yarn and cotton produced by blending a predetermined proportion of silver antibacterial agent is used, further antibacterial performance is exhibited in addition to the antibacterial function of warp. In addition, if a yarn made of synthetic fibers with hydrophilic groups is used as the third yarn, sweat and moisture are absorbed on the fiber surface and diffused quickly, making it a material with a high heat absorption rate and a cool refreshing feeling. Can be obtained.

  As the synthetic fiber having a hydrophilic group, for example, ethylene / vinyl alcohol fiber can be used. The yarn made of ethylene / vinyl alcohol fiber can be driven directly with a filament yarn made of ethylene / vinyl alcohol fiber as a weft, or can be driven with a false twisted yarn as a weft. It is also possible to drive as a weft by combining other yarns with other yarns.

  Further, it is more preferable to alternately weft (double pick) a yarn made of synthetic fiber having a hydrophilic group and a cotton yarn because a cool refreshing feeling can be obtained and moisture absorption and heat retention can be combined.

Further, as the third yarn to be driven as the weft 3, a yarn produced by melt spinning a polyester-based spinning raw material blended with a predetermined ratio of a far-infrared radiation material, or a yarn obtained by further false twisting this yarn can be used. .

  As the far infrared radiation material, fine powder such as germanium or far infrared radiation ceramic can be used. These far-infrared radiation materials are materials that radiate far-infrared rays due to body temperature, weight, friction, etc., so when a person sleeps on a sheet, the far-infrared radiation material depends on the weight and body temperature added to the sheet. Sheets that radiate can be obtained, and a sheet that can sleep comfortably and comfortably can be obtained.

  In addition, far-infrared radiation yarn made of far-infrared radiation fiber, false twisted yarn of this yarn, and cotton yarn can be alternately wefted (double pick) to weave the sheets, and far-infrared radiation function In addition to this, it is possible to have both hygroscopicity and heat retention, and a more preferable sheet can be obtained.

  As described above, in the sheet according to the present invention, the first yarn 2A obtained by false twisting a yarn produced by melt-spinning a polyester-based spinning raw material blended with a predetermined ratio of a photocatalytic metal oxide antibacterial agent and , A second yarn 2B obtained by false twisting a yarn produced by melt-spinning a polyester-based spinning raw material containing a predetermined proportion of silver antibacterial agent, and a warp 2, and various functions that exhibit a refreshing feeling and heat retention The sheet 1 is woven as the weft 3 as the third yarn comprising the anti-bacterial and deodorizing effects due to the photocatalytic function in an environment where light is irradiated, and in an environment where there is no light, silver is used. The sheet which exhibits the antibacterial function by the antibacterial agent can be obtained. Moreover, since a refreshing feeling can be obtained, it becomes the sheet which can sleep comfortably. Furthermore, since the antibacterial agent is blended in the resin raw material in advance, the antibacterial agent is not peeled off by washing or the like, and a stable antibacterial function can be exhibited over a long period of time.

  As described above, the sheet can exhibit an antibacterial function, provide a refreshing feeling, and can be comfortably sleepn. Therefore, the sheet can be suitably applied as a bedding product such as a sick person or an insomnia person.

  Therefore, the sheet according to the present invention has an antibacterial function and can exhibit a refreshing feeling, and is therefore suitable as a sheet suitable for a Japanese climate having a rainy and humid season.
