[Problem] To provide a textile product having excellent deodorizing function and excellent durability. [Solution] A textile product characterized in being obtained by using a deodorizing yarn as a darning yarn.

Description

Fiber products

The present invention relates to a textile product having excellent characteristics in the deodorizing function.

Many attempts have been made to provide various deodorizing products by imparting a deodorizing function to fibers. For example, in clothing such as work clothes, shirts, underwear, socks, stockings, and products such as sheets, pillows, pillow covers, etc., if sweat adheres, it will cause malodor due to decomposition of lipids in the sweat . In addition, in clothing or the like, when placed in a place where odor is produced, the odorous substance may be adsorbed by the fibers and become odorous. Many studies have been made on functional fibers that suppress the generation of malodors by decomposing such malodors, adsorbing odorous substances, and imparting antibacterial performance.

When such a deodorizing yarn is applied to a textile product, it is generally performed to use the deodorizing yarn for the fabric itself constituting the textile product. However, if the deodorizing yarn is used for the textile fabric itself, the amount of the expensive deodorizing yarn used becomes large, resulting in an increase in cost. Furthermore, since the deodorizing yarn is often inferior in strength to ordinary fibers, there is a problem that the physical properties of the fiber product are inferior.

Patent Document 1 describes that a deodorizing yarn is used as a sewing yarn. By setting it as such a method, a deodorizing function can be provided to a textile product with a small usage-amount. However, the use of deodorant yarn as the yarn is not described.

On the other hand, in a textile product, it is generally performed to perform threading for processing an end portion of a cloth. That is, the ends of the woven fabric and the knitted fabric are prone to fraying from the presence of the yarn hole. In order to prevent such fraying from the end, it is a common practice to perform a treatment with a warp yarn to make it difficult to fray. However, no attempt has been made to improve the performance of the textile product itself by imparting some function to such a warp yarn.

JP 2011-132636 A

In view of the above, an object of the present invention is to provide a fiber product having excellent deodorizing performance and excellent durability.

The present invention is a textile product obtained by using a deodorizing yarn as a warp yarn.
The warp yarn preferably has a tensile strength of 500 cN or more.
The yarn is preferably deodorizing performance under wet conditions with an ammonia reduction rate of 90% or more.

The fiber product of the present invention has a good deodorizing effect and is excellent in terms of product durability.

It is a figure which shows an example of the textiles of this invention. It is a figure which shows the enlarged view of the sewing part of the textiles shown in FIG.

The present invention is described in detail below.
The present invention is a textile product obtained by using a deodorizing yarn as a warp yarn. As shown in FIGS. 1 and 2, the yarn is used when the yarn is threaded to prevent fraying from the end of the fiber. That is, generally, fraying at the end portion is suppressed by sewing a thread near the end portion of the cloth.
A deodorizing yarn is used as the yarn used for such yarn threading.

Since the amount of use of the yarn is larger than that of the sewing yarn, a large amount of deodorizing yarn can be used. Furthermore, deodorizing performance can be imparted to any dough. Therefore, deodorizing performance can be imparted without changing the production process of the dough. Further, in the case of clothing or the like, the effect can be obtained efficiently by using the deodorizing yarn described above only in a portion where odor is particularly likely to occur.

(Deodorant yarn)
The deodorizing yarn used in the present invention is not particularly limited, but preferably has a polar functional group capable of chemically adsorbing odorous substances. Such a deodorizing yarn has a particularly excellent deodorizing function. The deodorant yarn having a polar functional group is not particularly limited. For example, a known arbitrary fiber such as a fiber in which a functional group that adsorbs a odorous substance to the fiber base material itself is bonded to the fiber base material by graft polymerization. Deodorant yarn can be used.

Among those described above, it is most preferable to use a fiber in which a functional group capable of adsorbing an odorous substance is bonded to the fiber base material itself by performing graft polymerization on the fiber. Such a deodorizing yarn is preferable in that it can sufficiently impart a deodorizing function to a fiber product with a use amount as a warp yarn because it has a very high ability to adsorb compounds serving as odor components. Hereinafter, such deodorizing yarn will be described in detail.

The above graft polymerization is performed by grafting an adsorbent substance such as an anionic adsorbent substance (that is, a compound having an anionic functional group) or a cationic adsorbent substance (that is, a compound having a cationic functional group) onto a compound constituting a fiber. Polymerize. The fiber thus obtained is excellent in washing resistance because the adsorptive substance is bonded to the substance constituting the fiber substrate through a chemical bond. Furthermore, since a cationic adsorbing substance and an anionic adsorbing substance can also be reacted together, it is possible to obtain a deodorizing performance that can deal with a wide range of substances. Furthermore, since an anionic functional group and a cationic functional group can be introduced at a high density, the deodorizing performance of the fiber itself is very high.

Examples of the anionic functional group include a carboxyl group, a sulfone group, a phosphoric acid group, a sulfoethyl group, a phosphomethyl group, and a carbomethyl group. These functional groups adsorb odorous substances such as ammonia and amines to obtain deodorizing performance. As the anionic adsorptive substance, the above-described compounds having a functional group and an unsaturated bond can be suitably used. Examples of such a cationic adsorbing substance useful in the present invention include acrylic acid, methacrylic acid, styrene sulfonic acid and salts thereof, and 2-acrylamido-2-methylpropane sulfonic acid.

Examples of the cationic functional group include a quaternary ammonium group and primary to tertiary amine groups such as an amino group, a methylamino group, a dimethylamino group, and a diethylamino group. Preferred cationic functional groups include quaternary ammonium groups and amino groups. The cationic functional group has the ability to adsorb polar substances and can neutralize with acidic substances such as hydrogen sulfide and mercaptans. As a result, the odorous substance that is an acidic substance is removed.

As the cationic adsorbing material, the above-described compound having a functional group and an unsaturated bond can be preferably used. Such cationic adsorbents include, for example, vinylbenzyltrimethylammonium salt, diethylaminoethyl methacrylate, dimethylaminoethyl acrylate, dimethylaminoethyl methacrylate, diethylaminoethyl acrylate, diethylaminomethyl methacrylate, tertiary butylaminoethyl acrylate, tertiary butyl. Mention may be made of aminoethyl methacrylate and dimethylaminopropylacrylamide. Two or more of these can be used simultaneously.

Of these, particularly useful reactive monomers are vinylbenzyltrimethylammonium salt and diethylaminoethyl methacrylate. A reactive monomer having a group that can be converted into a cationic dissociation group is also useful in the present invention. An example of such a reactive monomer is chloromethylstyrene.

In the graft polymerization, a graft polymerization may be performed using a compound having a hydrophilic group in combination. “Hydrophilic group” refers to a group that has an affinity for water and does not ionically dissociate when contacted with water (ie, a nonion). Such hydrophilic groups can trap water molecules present in the air, the trapped water molecules form an adsorbed water layer on the surface of the adsorbing material of the present invention, dissolve polar substances, and / or The ionic substance can be dissociated. Needless to say, such a hydrophilic group acts in water as well as in air.

Examples of the hydrophilic group include a hydroxyl group, a hydroxyalkyl group (wherein the alkyl group is preferably a lower alkyl group), an amino group, and a pyrrolidonyl group. More preferred hydrophilic groups include a hydroxyl group and a hydroxyalkyl group.
As the compound having a hydrophilic functional group, the above-described compound having a hydrophilic functional group and an unsaturated bond can be suitably used.

Examples of compounds useful in the present invention as the compound having a hydrophilic functional group include, for example, hydroxyethyl methacrylate, hydroxypropyl acrylate, vinyl pyrrolidone, dimethylacrylamide, ethylene glycol monomethacrylate, ethylene glycol monoacrylate, ethylene glycol monomethacrylate, ethylene There are glycol diacrylate, ethylene glycol dimethacrylate, triethylene glycol diacrylate and triethylene glycol methacrylate. Among these, particularly useful reactive monomers include hydroxyethyl methacrylate and vinyl pyrrolidone.

In the graft polymerization, two or more of the above-mentioned various components may be used in combination.
Specific examples of preferred combinations of functional groups when two or more are used in combination include a sulfone group, a carboxyl group, a quaternary ammonium group, and a hydroxyethyl group. Further, another preferred combination of functional groups in the present invention is specifically a sulfone group, a carboxyl group, a quaternary ammonium group, and a pyrrolidonyl group.

When graft polymerization is performed using a compound having a cationic functional group and a compound having an anionic functional group in combination, it is preferable in that a fiber capable of adsorbing a wide range of odorous substances can be obtained.

There are no particular limitations on the fibers used as the base material for the graft polymerization, and examples thereof include synthetic fibers such as polyester yarn, polyamide yarn, polyacrylic yarn, and rayon yarn, semi-synthetic fibers, natural fibers such as cotton yarn, wool, and silk yarn. Can be mentioned. In particular, it is preferable to use cotton yarn, nylon yarn and / or polyester yarn. Among these, polyamide yarns and cotton yarns are particularly preferable in that they have a structure capable of introducing a functional group into the molecular structure and have good compatibility when used by spinning with other fibers.

The fiber used as the base material may be any form of long fiber and short fiber. Further, spun yarn, twisted yarn, processed yarn, and the like may be used. In consideration of use as a deodorized yarn in a later step, cotton spun yarn or nylon long fiber is particularly preferable.

In the graft polymerization, the adsorptive substance to be bonded on the fiber substrate is preferably bonded at a ratio of 3 to 80% by weight with respect to the weight of the fiber substrate. By setting it as the coupling | bonding amount in the said range, it is preferable at the point which can obtain favorable deodorizing and deodorizing performance.

It is preferable to use the deodorizing yarn having high deodorizing performance. For example, when a test at an initial concentration of 100 ppm of ammonia is performed by the detector tube method described in the SEK mark fiber product certification standard shown by the Japan Fiber Evaluation Technology Council, the ammonia concentration after 2 hours is 1.5 ppm. It is preferable to use a fiber having a deodorizing function as follows.

A spun yarn, a twisted yarn, a processed yarn or the like may be produced by a known method using the fibers after the graft polymerization, and used as a deodorized yarn. In this case, spun yarns, twisted yarns, processed yarns and the like may be produced in combination with ordinary fibers not subjected to graft polymerization. In this case, among the yarns constituting the spun yarn, the twisted yarn, the processed yarn, etc., a function that adsorbs the odorous substance to the fiber base material itself by performing graft polymerization on the above-described fiber at a ratio of 30% by weight or more. It is preferred to use fibers with bonded groups. If the amount of the fiber used is less than 30% by weight, it is not preferable because there is a possibility that sufficient deodorizing performance cannot be imparted. Moreover, what processed the fiber after processing, such as a spun yarn, a twisted yarn, and a processed yarn, to make a deodorant yarn may be performed.

Furthermore, a twisted yarn obtained by combining a cation-adsorptive fiber and an anion-adsorptive fiber can also be used. This is preferable in that a fiber product that can deal with many kinds of odorous substances can be obtained.

It is preferable that the above-mentioned warp yarn has a tensile strength of 500 cN or more. The deodorant yarn tends to have a reduced tensile strength by performing a treatment for imparting deodorant performance. When a warp thread having insufficient tensile strength is used, thread breakage tends to occur during the overlock stitching, and further, problems such as fraying easily occur when used as a textile product. Therefore, it is preferable not to cause such a problem by devising the deodorizing yarn having the above-described tensile strength by devising to increase the tensile strength.
In order to use the above-mentioned deodorant yarn, which is a short fiber, to obtain the above-mentioned tensile strength, it is preferable to use a double twisted or three twisted twisted yarn using the deodorized yarn in part or in whole. . Hereinafter, such a twisted yarn will be described in detail.

(Twisted yarn using deodorant yarn, which is a short fiber)
First, the case where the deodorizing yarn is a short fiber will be described in detail below. An example of the case where short fibers are used is a case where cotton yarn is used as a base fiber for deodorant yarn. In this case, it is possible to use a spun yarn after performing graft polymerization in a short fiber state, or a spun yarn obtained by graft polymerization.

When used as the above-described twisted yarn, all yarns constituting the twisted yarn may be deodorized yarns, but at least one may be normal fibers (that is, fibers not subjected to deodorizing treatment). Deodorant yarn often has lower strength than normal fibers. For this reason, in order to reinforce the strength, it is preferable to use twisted yarn in combination with ordinary fibers.

The normal fiber is not particularly limited and may be the same type of fiber as the deodorant yarn or a different type of fiber, but it is preferable to use the same type of fiber.

The spun yarn constituting the twisted yarn preferably has a yarn count of 10 to 50 for both the deodorant yarn and the normal fiber. If the yarn count is less than 10th, it will not fit into the needle hole of a normal overlock sewing machine, and when used as a overlock thread, the overlock will become too thick and the skin will be stimulated by friction. That is not preferable. Furthermore, if the yarn count is 50 or more, there is a risk that the strength may be insufficient.

The twisted yarn is usually obtained by combining a plurality of fibers subjected to a lower twist (that is, twisting of each of the fibers constituting the twisted yarn) and then performing an upper twist (twisting as a whole twisted yarn). In the twisted yarn used in the present invention, it is preferable that the twisting direction is reverse between the lower twist and the upper twist. That is, when the lower twist is a Z twist, the upper twist is preferably an S twist, and when the lower twist is an S twist, the upper twist is preferably a Z twist. Such twisting is preferable in that the twisted yarn is less likely to be untwisted.

It is preferable that the number of twists is 15 to 30 times / inch. By setting the number of twists in such a range, it is possible to secure the strength when used as a sewing thread and it is preferable in that it can withstand high-speed sewing by an industrial sewing machine.

The above twist is preferably 15 to 30 times / inch. By setting the number of twists in such a range, it is possible to secure the strength when used as a sewing thread and it is preferable in that it can withstand high-speed sewing by an industrial sewing machine.

The twisted yarn is preferably provided with wax. This is preferable in that the sliding of the thread during sewing is improved.

(Deodorant fiber which is long fiber)
Next, the case where the deodorizing yarn is a long fiber will be described in detail below. The deodorant fiber which is a long fiber includes nylon long fiber, polyester long fiber and the like as a fiber serving as a base material. The fiber serving as the substrate is preferably a multifilament having a total fineness of 50 to 200 dtex. Use of a material in this range is preferable in that a sufficient deodorizing function and strength can be secured when the sewing thread is used.

Since the deodorizing fiber which is the above-mentioned long fiber can have a relatively high strength, it is not always necessary to use a twisted yarn, and an ordinary multifilament or a drawn yarn using the same may be used. it can.
When using the deodorizing fiber which is a long fiber as a twisted yarn, it is preferable to twist two or three yarns into a twisted yarn. At that time, all the yarns constituting the twisted yarn may be deodorized yarns, but at least one normal fiber (that is, fibers not subjected to deodorizing treatment) may be used. Deodorant yarn often has lower strength than normal fibers. For this reason, in order to reinforce the strength, it is preferable to use twisted yarn in combination with ordinary fibers. The normal fiber is not particularly limited and may be the same type of fiber as the deodorant yarn or a different type of fiber, but it is preferable to use the same type of fiber.

There is also an application in which stretchability is required in the deodorized yarn. This means that in the use of clothes having high elasticity such as inner shirts and sweaters, the warp yarn itself needs to be elastic. In such a case, when using a deodorizing yarn made of long fibers, it is preferable to use a bulky processed yarn. By carrying out the bulky processing, the deodorized yarn is preferred in that it can also be stretchable.

It is preferable that the deodorizing yarn using the above-mentioned long fibers is provided with wax. This is preferable in that the sliding of the thread during sewing is improved.

(Deodorization performance under wet conditions)
The warp yarn used in the present invention preferably has an ammonia deodorization rate of 90% or more as measured by wet conditions described in detail below. That is, it is preferable in that the deodorizing function is further improved by using the yarn having such a high deodorizing performance. The ammonia reduction rate is more preferably 95% or more, and further preferably 99% or more. Note that the measurement is performed under wet conditions because when the garment is worn, the portion where the odor is likely to occur is a portion where the garment is moistened by sweat because the portion where the odor is likely to be generated is easily sweated.

(Measurement method of deodorant performance under wet conditions)
Into a 5 liter Tedlar bag or smart bag, put 1 g of warp yarn and 3 L of air, and drop 1 mL of water. A 400 ppm concentration of ammonia is sealed inside, and the ammonia concentration in the air is measured over time. With respect to the ammonia concentration after 2 hours, how much is adsorbed on the fiber with respect to 400 ppm at the start of the test is calculated in%.

(Fiber products)
The textile product of the present invention is characterized in that the deodorizing yarn as described above is used as a warp yarn. As an example of such a textile product, FIGS. 1 and 2 are shown.

FIG. 1 is a diagram showing the shape of a normal underwear. In addition, FIG. 1 has shown the state turned over. In use, it is usually used so that the overlocked portion is hidden with the reverse side upside down in the state of FIG. Such an undergarment is usually formed as a knitted fabric, and the neckline 3, the armhole 4, the opening portion 5 of the sleeve, the side 6, the hem 7, the shoulder 8, and the like are overlocked with an overlock thread. The textile product of the present invention is used for the above-mentioned deodorant yarn to carry out the stitching at these portions. FIG. 2 shows an enlarged view of the portion shown as 2 in FIG. 1 is a part of the shoulder 8 and is sewn. Further, overlock stitching is performed by the overlock thread 1 to prevent fraying at the end. The deodorizing yarn is used as the yarn 1.

Overlock stitching is performed by a lock sewing machine or the like in order to prevent fraying at the end of a woven fabric, knitted fabric, or the like, and a well-known overlock stitch can be performed as such a method. For example, it can be performed by a known method such as one-needle overlock stitching, two-needle overlock stitching, or interlock stitching.

All of these over stitches may be performed with the deodorizing yarn, but only over a portion thereof with the deodorizing yarn may be performed. That is, there is a part that is particularly likely to generate odor in the human body. For example, the heel and neck are likely to smell. For this reason, for example, the neckline and neckline stitches may be performed with the deodorizing thread, and the other portions may be stitched with ordinary fibers.

Moreover, in this invention, although the said deodorizing thread | yarn is used as a warp thread | yarn, it does not prevent using the said deodorizing thread | yarn for part or all of a sewing thread | yarn or cloth simultaneously. When the deodorizing yarn is used in sewing threads and fabrics, the deodorizing function of the textile product of the present invention can be further improved. However, from the viewpoint of fiber product strength and cost, the deodorizing yarn is more preferably used only for the deodorizing yarn.

The textile product of the present invention can be used in applications such as work clothes, underwear, socks, bedding, clothes, coats, sweaters, shirts, nightclothes, Japanese clothes, gloves or hats. Furthermore, it can be used in any field where odor is likely to occur, such as a seat cover in a vehicle (airplane, train, etc.), a sofa cover for home use, a towel, a cloth towel, a toilet cover, and slippers.

EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

Example 1
After removing impurities from the 40th cotton yarn, graft polymerization was performed to bond a functional group that adsorbs odorous substances to produce a deodorant yarn. When this deodorized yarn was tested at an initial concentration of 100 ppm of ammonia by the detector tube method described in the SEK mark textile product certification standard, a result that the ammonia concentration after 2 hours was 0.2 ppm was obtained. Further, when a tensile strength test was performed by the general spun yarn test method described in JIS L 1095, a result of 330 cN was obtained.

After twisting the above two deodorant yarns and one regular yarn for strength reinforcement, heat set at about 80 ° C to prevent untwisting at the time of sewing. Yarn was produced. At the time of production, each of the deodorized yarn and the regular yarn was twisted 20 times / inch in the Z twist direction as a lower twist. Further, 18 times / inch twist was applied in the S twist direction as the upper twist. Further, a wax agent treatment was performed to improve slippage during sewing. When this deodorized yarn was tested for tensile strength by a general spun yarn test method described in JIS L 1095, a result of 902 cN was obtained.

Furthermore, when the obtained deodorized yarn was subjected to the deodorization test under the above-mentioned wet conditions, the ammonia reduction rate was 99.9%.

The underwear having the shape shown in FIG. 1 was produced using the twisted yarn thus obtained as a deodorizing yarn. In the production, 100% polyester was used as the fabric, and cotton spun yarn 40/3 was used as the sewing yarn, and the production was performed by a general knitting process and a sewing process. The amount of deodorized yarn used was 4.3 g / wear for the entire underwear.

In the obtained underwear, it cut | disconnected by 10x10 cm so that the overlock sewing part might be included, and the deodorizing function test was done with respect to this. The amount of deodorized yarn used was 0.4 g / 10 × 10 cm 2% by weight relative to the entire sample. The deodorant function test method was performed by the method shown below.
(Deodorization test method)
3 liters of air was put into a 5 liter Tedlar bag or smart bag, and 100 ppm of ammonia was further enclosed. The ammonia concentration in the internal air was measured over time (blank test). A similar test was performed with the above-described test sample sealed in a Tedlar bag.
The results are shown below. In addition, the same test was done also about the deodorizing thread | yarn itself used by this invention. In that case, the result that the ammonia concentration after 2 hours was 0.2 ppm (reduction rate 99.8%) was obtained.

(Comparative example)
As a comparative example, a similar test was conducted on a polyester fabric obtained by using the polyester fiber used in the manufacture of the undergarment fabric of the example (no over stitching with deodorant yarn).

From the results in Table 1, it was revealed that the fiber product of the present invention exhibits an excellent deodorizing effect in a short time.

(Example 2)
By performing graft polymerization on the 78dT single yarn, a functional group that adsorbs the odorous substance was bonded to produce a deodorant yarn. Two deodorant yarns described above and one regular yarn for reinforcing strength were twisted together to produce a deodorized yarn. At the time of production, each of the deodorized yarn and the regular yarn was twisted at 750 T / M in the Z twist direction as a lower twist. Further, a 630 T / M twist was applied in the S twist direction as an upper twist. Further, a wax agent treatment was performed to improve slippage during sewing.
The warp yarn thus obtained was subjected to the deodorization test under the wet conditions described above, and the ammonia reduction rate was 99.6%.

A cardigan having the shape shown in FIG. 1 was produced using the twisted yarn thus obtained as a deodorizing yarn. In the production, 70% acrylic + 30% hair was used as the fabric, and nylon filament yarn 78dT / 3 was used as the sewing yarn, and the production was performed by a general knitting process and a sewing process.
When a cardigan wearing test thus obtained was tested, an excellent deodorizing function was confirmed.
