Description

  The present invention relates to a functional yarn that can be used for clothes and the like and does not generate a bad odor even when the clothes are dried in a room after washing, and a functional woven or knitted fabric using the same.

  In recent years, so-called “room drying” in which clothes, sheets, towels and the like after washing are dried indoors due to changes in lifestyle and residential environment. This is due to various reasons such as an increase in the percentage of people who wash at night, crime prevention reasons, countermeasures against hay fever and yellow sand. Furthermore, in recent years, it can be considered that more and more rooms are being dried because of measures such as PM2.5 flying from China.

  However, when clothes and the like after washing are dried in the room, it takes time to dry, and the time for which the clothes and the like are left in a damp state becomes longer. In such a state, a bad odor called “room-dried odor” may occur from clothes dried indoors. Such bad odors will cause discomfort when worn or used, and countermeasures have been desired.

  Therefore, it is conceivable to shorten the drying time of clothes in order to prevent room-drying odor. Then, if a quick-drying material is used for clothes etc., the room odor can be prevented. For example, in the following Patent Document 1, a multi-layered knitted fabric is used, arranged so that the single yarn fineness of the fibers constituting the surface layer is smaller than the single yarn fineness of the fibers constituting the back surface layer, and drying time is set. It has been proposed that it can be shortened. As a result, it is conceivable to reduce the occurrence of room-dried odor.

  Further, in Patent Document 2 below, a polyester X-type cross-sectional fiber having a high water absorption and quick-drying property is proposed by utilizing a hydrophobic filament yarn having an irregular cross section and promoting a capillary phenomenon by combining different filament filament yarns. . Since this fiber is also characterized by quick drying, it is possible to shorten the drying time and to reduce the occurrence of room-drying odor.

  By the way, in the said patent document 1 and the said patent document 2, it tries to shorten generation | occurrence | production time after washing and to prevent generation | occurrence | production of the room drying odor. However, these all use hydrophobic synthetic fibers such as polyester, and use a complicated multilayer structure or irregularly shaped cross-section fibers, and are not compatible with general clothing. Furthermore, in the case of cellulosic fibers having large water retention such as cotton and rayon, there is a problem that it is difficult to shorten the drying time after washing.

  Therefore, the present invention addresses the above and prevents the occurrence of a room-drying odor even when clothes containing cellulosic fibers with high water retention properties such as cotton and rayon are air-dried. It is an object to provide a functional yarn that can be produced and a functional woven or knitted fabric using the functional yarn.

  In solving the above-mentioned problems, the present inventors, as a result of diligent research, have developed a functional agent having a function of preventing bad odor caused by drying in a room (hereinafter referred to as a foul odor prevention function), particularly in a yarn state of a cellulosic fiber-containing yarn. The inventors have found that the above-mentioned problems can be solved by providing an endoplasmic reticulum having a bilayer multi-layer structure, and have completed the present invention.

That is, according to the description of claim 1, the functional yarn according to the present invention is

The bilayer multilayer vesicle is a cationic vesicle having a cationic group on the outermost surface thereof,
By treating the dyed cellulose fiber-containing yarn with the cationic vesicle, the cation group of the vesicle and the anion group of the dye dyed on the cellulose fiber are fixed by ionic bonds. Features.

  According to the description of claim 4, the functional woven or knitted fabric according to the present invention is knitted and knitted using the functional yarn according to any one of claims 1 to 3.

  Moreover, according to the description of Claim 5, the functional woven or knitted fabric according to the present invention is woven using the functional yarn according to any one of Claims 1 to 3 as either a weft or a warp. Become.

  According to the structure of the said Claim 1, the vesicle of the bilayer multilayer structure in which the functional agent which has a malodor prevention function was included in the oil layer is adhering to the cellulose fiber containing thread | yarn. This endoplasmic reticulum has a high affinity with cellulosic fibers and does not fall off by washing.

  In addition, undecylenic acid monoglyceride is included in the oil layer of the endoplasmic reticulum as a functional agent having a foul odor preventing function, and this also does not easily fall off by washing, and exhibits its effect when the room is dried after washing.

  Moreover, according to the structure of the said Claim 2, since a functional thread | yarn is processed in the state which wound the normal thread | yarn around the cheese-like package, the adhesion | attachment of the endoplasmic reticulum with respect to a cellulosic fiber becomes uniform. .

  Moreover, according to the structure of the said Claim 3, since an endoplasmic reticulum forms an ionic bond with the dye dye | stained to the cellulosic fiber, the adhesion of the endoplasmic reticulum to a cellulosic fiber becomes stronger, and washing durability Is further improved.

  Moreover, the said Claim 4 and the said Claim 5 are the functional knitted fabrics using the functional yarn described in said each claim, and can achieve the effect similar to the said functional yarn more specifically. it can.

  From the above, according to the present invention, even when clothes containing cellulosic fibers having a large water retention capacity such as cotton and rayon are air-dried, a functional yarn that can prevent the occurrence of a room-drying odor, and A functional woven or knitted fabric using the same can be provided.

It is the schematic which shows the cross section of the endoplasmic reticulum of the bilayer membrane multilayer structure fixed to the functional thread | yarn which concerns on this invention. It is the schematic which shows the state which the vesicle of FIG. 1 adhered to the surface of the cellulosic fiber which comprises a functional yarn. It is the schematic which shows the state which the vesicle of FIG. 1 ion-bonded with the dye dye | stained to the cellulose fiber. It is the schematic which shows an example of the functional textiles based on this invention.

  The functional yarn according to the present invention comprises a cellulosic fiber-containing yarn. Here, the cellulosic fiber-containing yarn may be a yarn composed only of cellulosic fibers such as cotton yarn, or may be cellulose such as polyester / cotton blended yarn or acrylic / rayon filament blended yarn. It may be a yarn composed of system fibers and other fibers. Here, examples of the cellulosic fibers include natural fibers such as cotton and hemp, and regenerated fibers such as rayon (viscose rayon), cupra, polynosic, and tencel.

  In the functional yarn according to the present invention, a functional agent (described later) having a malodor prevention function is fixed to at least the surface of the cellulosic fiber. Specifically, in a yarn composed only of cellulosic fibers such as cotton yarn, the functional agent is fixed to the entire yarn. On the other hand, in yarns composed of cellulosic fibers and other fibers such as polyester / cotton blended yarn, the functional agent may be fixed only to the cellulosic fibers, or both the cellulosic fibers and other fibers. A functional agent may be fixed to the surface. This is because the functional agent used in the present invention has a different affinity depending on the type of fiber, and particularly has a strong affinity for cellulosic fibers.

  In the present invention, the foul odor prevention function means that when clothes, sheets, towels, etc., are dried in the room after washing, it takes time to dry, even if the clothes are left in a damp state for a long time. A function that prevents the generation of a foul odor called clothes drying odor from clothing.

  Here, the room-drying odor is a complex odor of many odors, and the main odor substance is said to be due to 4-methyl-3-hexenoic acid generated by Moraxella Osloensis. This Moraxella is a resident bacterium belonging to the Gram-negative bacterium.

  In the present invention, undecylenic acid monoglyceride is used as a functional agent having a malodor prevention function. This undecylenic acid monoglyceride is a substance that is a component of human sweat and plays a major role in the cleansing action of the skin. Moreover, undecylenic acid monoglyceride has little irritation to the skin, is safe and has high affinity with the skin. Furthermore, since this substance is lipophilic, it has the effect of providing skin smoothness and at the same time keeping the skin clean.

  This undecylenic acid monoglyceride exerts an antibacterial action against Moraxella, so that the growth of Moraxella can be suppressed when clothing or the like is placed in a damp state when the room is dried. As a result, the number of Moraxella bacteria on the surface of clothing and the like is reduced, the amount of 4-methyl-3-hexenoic acid generated is suppressed, and no room-drying odor is generated.

  This undecylenic acid monoglyceride is oleophilic and has a low affinity for cellulosic fibers, and if it is simply applied to the fibers, it easily falls off the fibers by washing. Therefore, it is necessary to stably fix the undecylenic acid monoglyceride on the fiber. The present invention is characterized in that it exhibits a washing-resistant odor prevention function by encapsulating undecylenic acid monoglyceride in the endoplasmic reticulum of a bilayer multilayer structure that has a particularly strong affinity for cellulosic fibers. To do.

  The present invention will be described below with reference to the drawings. FIG. 2 shows a state in which a functional agent (an endoplasmic reticulum 10 described later) is uniformly fixed to the surface of the cellulosic fiber 21 constituting the functional yarn. The size of the endoplasmic reticulum 10 is from a micron size to a sub-micron size, and it is difficult to enter the amorphous part of the cellulosic fiber, and it seems that many of them are fixed on the fiber surface.

  In the present invention, the functional agent having the function of preventing malodor consists of a vesicle having a bilayer multilayer structure. As shown in FIG. 1, the vesicle 10 includes water layers 11a and 11b and hydrophobic oil layers 12a and 12b. , 12c have a bilayer multilayer structure (also referred to as a vesicle structure) in which multiple layers are stacked.

  In this bilayer multilayer structure, a surfactant S such as phospholipid or alkyl quaternary ammonium salt forms a bilayer membrane, and the hydrophilic portions Sa of the surfactant S are arranged without gaps so that the water layers 11a and 11b are formed. In addition, the hydrophobic portions Sb of the surfactant S are arranged without gaps, and the oil layers 12a, 12b, 12c are alternately formed.

  In the present invention, undecylenic acid monoglyceride, which is a functional agent having a malodor prevention function, is included in the oil layers 12a, 12b, and 12c. Note that the functional agent having a malodor prevention function may be undecylenic acid monoglyceride itself or a substance containing undecylenic acid monoglyceride.

  Here, the amount of undecylenic acid monoglyceride encapsulated in the endoplasmic reticulum 10 may be in a range that can express the malodor prevention function of undecylenic acid monoglyceride, and is, for example, 10 to 40% by weight with respect to the weight of the endoplasmic reticulum 10. May be.

  In the present invention, another functional component such as a skin care component may be included in the endoplasmic reticulum 10. When the skin care component is included, the functional yarn according to the present invention and the functional woven or knitted fabric using the functional yarn act as a component that protects the skin when used in clothes, sheets, towels and the like that touch the skin. In that sense, these skin care ingredients are preferably ingredients used in cosmetics.

  As this skin care component, there are hydrophilic ones such as chamomile extract, various amino acids and silk protein. Among these, chamomile extract is preferable. These hydrophilic skin care components are encapsulated in the water layers 11a and 11b.

  Here, the chamomile extract is an extract extracted from the flowers of the chamomile plant of the family Asteraceae, which includes camazulenes, azulene, bisabolol, amino acids, tannins, flavonoids, etc., moisturizing action, sweating action, purification action, sedative action It is said that it has a painful action, and also has a whitening action, an active oxygen suppression action and the like.

  The vesicle 10 having a bilayer multi-layer structure may be produced by using an ordinary vesicle production method. An oil layer is formed in a dispersion in which a surfactant S such as phospholipid or quaternary ammonium salt is dispersed. What is necessary is just to disperse and mix the animal and vegetable oil for forming, and to adjust with emulsification dispersion apparatuses, such as an ultrasonic emulsifier, a nanomizer, or a homogenizer. In the present invention, lipophilic undecylenic acid monoglyceride may be mixed in advance in animal and vegetable oils for forming the oil layer and then emulsified and dispersed.

  Here, the manufacturing method of the functional yarn according to the present invention will be specifically described. First, a cellulosic fiber-containing yarn is prepared. The cellulose-based fiber-containing yarn may be a yarn composed of only cellulose-based fibers such as cotton yarn as described above, or may be a polyester / cotton blended yarn or an acrylic / rayon filament blended yarn. Alternatively, the yarn may be composed of cellulosic fibers and other fibers.

  First, unscoured cellulosic fiber-containing yarn is wound into a cheese-like package, set in a cheese dyeing machine, and scoured and bleached by a normal method. Furthermore, it dye | stains as needed, and the fixing process (henceforth an endoplasmic reticulum treatment) of the vesicle of bilayer multilayer structure is performed in this cheese dyeing machine after that. In this way, scouring / bleaching, if necessary, dyeing, and endoplasmic reticulum treatment can be performed in the same cheese dyeing machine. And the productivity of functional woven or knitted fabric is improved.

  The endoplasmic reticulum treatment may be carried out in accordance with the dyeing treatment. For example, it is a treatment solution in which 1 to 8% by weight, preferably 2 to 4% by weight of endoplasmic reticulum is dispersed with respect to the weight of the treated yarn, and the pH is 4 to 5. As above, the treatment may be performed at 40 to 80 ° C. for 10 to 60 minutes. In the treatment liquid, a binder for strengthening the adhesion of the endoplasmic reticulum may be used in combination. Moreover, you may make it use normal fiber processing agents, such as a softening agent, together. By this endoplasmic reticulum treatment, the endoplasmic reticulum in the treatment liquid is selectively exhausted and fixed to the cellulosic fibers.

  Here, the endoplasmic reticulum is preferably cationic in the treatment liquid. When the endoplasmic reticulum has a cationic property, it is more selectively exhausted to the cellulosic fiber and firmly adhered to the cellulosic fiber without using a binder.

  In addition, when the cellulosic fiber-containing yarn is dyed in advance, it is considered that the yarn is more firmly fixed to the cellulosic fiber. For dyeing cellulosic fibers, reactive dyes or direct dyes are usually used. These dyes have an anionic hydrophilic group in the molecule, and the anionic hydrophilic group remains after dyeing.

  FIG. 3 is an enlarged schematic view of the surface of the cellulosic fiber 21 constituting the cellulosic fiber-containing yarn. The dye D is dyed on the cellulose molecules 22 constituting the cellulosic fiber 21. This dye D is anionic (-) in the endoplasmic reticulum treatment solution, and the endoplasmic reticulum 10 having a cationic property (+) is attracted thereto to form an ionic bond.

  Therefore, it is considered that the exhaustion rate and the fixing rate of the endoplasmic reticulum are further improved when the endoplasmic reticulum treatment is performed on the dyed cellulosic fiber, compared with the case where the endoplasmic reticulum treatment is performed on the unstained cellulosic fiber.

  Next, a method for producing a functional woven or knitted fabric according to the present invention will be described. The functional woven or knitted fabric according to the present invention may be produced by a normal weaving process or knitting process using a cellulosic fiber-containing yarn. In this case, only the functional yarn may be used, or the functional yarn and the unprocessed normal yarn may be used. Further, no limitation is imposed on the woven structure or the knitted structure.

  Further, after forming a functional woven or knitted fabric, a processing usually performed on the woven or knitted fabric, for example, processing such as softening processing, resin processing, or shape stabilization processing may be performed. In these normal knitting and knitting processes, the vesicles of the functional yarn do not fall off.

  Hereinafter, functional textiles having a malodor prevention function according to the present invention will be described with reference to examples.

  As Example 1, a functional fabric made of a plain fabric using a functional yarn made of 40th cotton yarn was woven. FIG. 4 shows a schematic diagram of the functional fabric 100 according to the first embodiment. This functional fabric 100 uses 40th cotton functional yarn for the weft 20 and the warp 30.

  The functional yarn used for the weft 20 and the warp 30 was obtained by scouring, bleaching, and dyeing unscoured cotton yarn with a cheese dyeing machine, and then performing the aforementioned endoplasmic reticulum treatment in the same cheese dyeing machine. The endoplasmic reticulum treatment was carried out at 60 ° C. for 20 minutes at a pH of 4 to 5 using 3% by weight of the endoplasmic reticulum based on the yarn weight. Further, no binder is used in combination with the endoplasmic reticulum treatment.

  As described above, in the functional fabric 100 according to the first embodiment, the endoplasmic reticulum 10 having a foul odor preventing function is uniformly fixed to both the weft 20 and the cotton yarn constituting the warp 30. Moreover, this functional fabric 100 was only subjected to softening with a normal softener after weaving, and was not subjected to resin processing or the like.

  The functional fabric according to Example 1 was evaluated for its malodor prevention function. In addition, a standard cotton fabric was similarly evaluated as Comparative Example 1. The malodor control function was evaluated by an antibacterial test that measures the growth rate of Moraxella.

表１の各値を比較すると、標準綿布（比較例１）においては、接種直後の生菌数の常用対数値が４．３であり１８時間後の値が７．５と増加しており、増殖値３．２とモラクセラ菌が大幅に増殖している。これに対して、本考案に係る機能性織物（実施例１）においては、接種直後の生菌数の常用対数値は標準綿布（比較例１）と同じ４．３であったが、１８時間後の値が１．３以下と減少しており、増殖値−３．０以下、即ち、殺菌活性値３．０以上とモラクセラ菌が大幅に減少している。このことにより、標準綿布（比較例１）と比較した静菌活性値が６．２以上と良好な値を示している。 The antibacterial test was conducted according to JIS L 1902: 2008 quantitative test (bacterial solution absorption method). The method for measuring the viable cell count was based on the pour plate culture method. The test strain used was Moraxella Osloensis ATCC 19976. Table 1 shows the antibacterial effect of the functional fabric according to Example 1 and the standard cotton fabric according to Comparative Example 1.

When comparing the values in Table 1, in the standard cotton cloth (Comparative Example 1), the common logarithm of the number of viable bacteria immediately after inoculation is 4.3 and the value after 18 hours is increased to 7.5, Growth value 3.2 and Moraxella bacteria are growing significantly. In contrast, in the functional fabric according to the present invention (Example 1), the common logarithm of the number of viable bacteria immediately after inoculation was 4.3, the same as that of the standard cotton cloth (Comparative Example 1), but 18 hours. The later value is reduced to 1.3 or less, and the growth value is -3.0 or less, that is, the bactericidal activity value is 3.0 or more, and Moraxella bacteria are greatly reduced. Thereby, the bacteriostatic activity value compared with standard cotton cloth (comparative example 1) has shown the favorable value with 6.2 or more.

  Thus, as is apparent from Table 1, the functional fabric of Example 1 has an excellent antibacterial effect against Moraxella bacteria. As a result, when clothes are air-dried, it takes time to dry. Even when the time for which the garment is left in a damp state becomes longer, it does not generate a room-drying odor from dry clothing or the like, and has a function of preventing malodor.

  From the above, in the present invention, even when clothes such as cotton and rayon containing large water-retaining cellulosic fibers are air-dried, functional yarn that can prevent the occurrence of room-dried odor, and A functional woven or knitted fabric using the same can be provided.

  The functional yarn according to the present invention and the functional woven or knitted fabric using the same do not generate a bad odor called a room-drying odor when the room is air-dried after washing. Therefore, it can be widely used in the textile industry and fashion industry as clothing, such as dress shirts, casual shirts, and pants, as well as sheets, towels, underwear, innerwear, pajamas, socks and tights.
