Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a multi-layered towel having a terry structure using bamboo fibers and a multi-layered towel produced therefrom,

The present invention relates to a method for producing a multi-layered towel having a terry structure using bamboo fibers and a multi-layered towel produced therefrom.

Generally, a towel used to remove moisture or sweat that occurs after a bath or exercise is woven with cotton yarn or the like to quickly absorb moisture or sweat remaining on the skin without irritating the skin.

However, when 100% cotton yarn is used, there is a limitation in absorbing power, and not only the hygroscopicity is deteriorated during long-term use, but also there is a disadvantage that it becomes rigid and makes sense of heterogeneity when contacting with skin. In order to overcome such disadvantages, Korean Patent No. 10-1203525 discloses a method of manufacturing a towel in which a pile is formed using hemp fiber. However, since the hemp fiber itself has insufficient elasticity and stiff texture, There is a disadvantage that many softeners have to be treated in order to make them.

To overcome these disadvantages, synthetic fibers or towels using a mixture of synthetic fibers and natural fibers have been produced in addition to natural fibers. Korean Patent Laid-Open No. 10-2004-0016620 discloses a superabsorbent towel fabric in which a slope of a pile is inserted into a papilla tissue using polyester microparticles of nylon. However, when a loop or curl is formed by using microfibers, there is a disadvantage in that a soft touch tends to be caused due to a feeling of sticking to the microfiber-specific skin. In addition, terry fabrics using synthetic fibers are not only difficult to dye the split yarn used as a pile in the dyeing process after manufacturing the fabric, but also have a disadvantage that the fastness to dyeing is poor and the discoloration becomes severe.

Thus, development of a terry fabric excellent in dyability while maintaining soft touch and high hygroscopicity has been demanded.

At this time, the inclination of the file can include inclination of the filaments composed of composite fibers of polyester and polyamide, and covering yarns composed of bamboo fiber or rayon-based regenerated fiber in a 1: 1 volume ratio.

Another aspect of the present invention is to provide a method of forming a weft yarn, comprising: a bottom portion including ground warp yarns and weft yarns; a weft yarn passing through between the weft yarns to form a file; Wherein the warp and weft yarns are 20 to 40 cotton yarn numbers, the warp yarns are 60 to 160 D / 72 F, the covering yarns are yarns of 10 to 30 yarns, Lt; / RTI >

Hereinafter, a method for manufacturing a multi-layer towel according to the present invention and a multi-layer towel according to the present invention will be described in detail.

The method of manufacturing a towel according to the present invention begins by fabricating a terry fabric to form a loop by feeding a file tilt between weft yarns at the bottom weaving including terraces and wefts as in step a).

The term " terry fabric " used in the present invention is generally referred to as a warp pile fabric. The warp pile fabric is made of a kind of warp and weft yarns, and then a separate file warp is arranged. Or to make a drink. More specifically, it refers to a multi-layered pile fabric that forms a loop or curl as a special slope, called a terry pile.

The ground yarn and weft yarn fed to the weaving unit in the step a) may be natural fibers commonly used in the art, preferably cotton fibers, hemp fibers, fleece fibers, regenerated fibers, especially those produced through melt spinning or melt spinning Both regenerated fibers and cellulosic fibers can be used. Most preferably, cotton fiber is eco-friendly, which is an advantage of natural fibers, and has no adverse effect on the skin.

The finenesses and the weft yarns have a cotton yarn number of 20 to 40, which is advantageous for production and is preferable for the good feel of the manufactured towel.

The file warp yarns are composed of fibers made of different materials and include covering yarns spirally wound in examination and examination as shown in FIG. 2 or 3, or may be formed of combined yarns in which the yarns and the covering yarns are mixed. The manufacturing method may be a normal joining method or a covering method. However, judging and covering yarn yarns are preferable because yarn yarns and twist yarns at a volume ratio of 1: 1 can satisfy the tensile strength at the time of weaving.

The file warp according to the present invention can be separated from each other in the primary dyeing step. This action is caused by shrinkage of the filament warp depending on the temperature of the primary filament composition used in the primary dyeing step, because the tension received in the warp direction is removed by the temperature of the primary filament composition and shrinkage occurs to be. In addition, the material of the screening yarn and the material of the covering yarn are different from each other.

The above examination is for maintaining the volume or shape of the tilt of the file, and it is not limited to the type of fiber used in the art, but preferably, any one selected from polyester, polyolefin, polyamide and polyacrylic, Polyester composite yarn (N / P composite yarn) which emits mixed fibers of polyamide and polyester, in particular, through the same spinning process. When the dyeing process is carried out, The dye capable of dyeing the bottom portion and the file inclination can be performed in a single bath without mutual influence.

The term " N / P composite yarn " used in the present invention is a kind of special yarn, which is a fiber produced by spinning nylon and polyester through the same spinneret roll. In this case, one component may be dissolved or divided into fine filaments through physical processing. The filament warps according to the present invention can be separated by separating the examination and covering yarns from each other through the primary dyeing process, This is because the N / P composite yarn is more heat shrinkable than the bamboo fiber that forms the covering yarn.

When the above screening is an N / P composite yarn, it is preferable that the blending ratio is 70 to 90% by weight of the polyester and 30 to 10% by weight of the polyamide.

It is also possible to use any of yarn or filament yarn for the above examination, and it is not limited to the form of the cross section when the examination is filament yarn, but preferably triangular (Y) or Y- It is good because it is effective.

The fineness of the examination is preferably 60 to 160 D / 72F. When the fineness of the above examination is less than 60 D / 72 F, the cut rate is increased in the production of the towel, and in the case of 160 D / 72 F, the fiber becomes thick and the fabricability may be remarkably lowered.

 The covering twisting yarn indicates the effect of the tilting of the file and the towel to be manufactured, and the visual or tactile feeling of the covering yarn can be displayed on the outside as a whole effect of the composite yarn. The covering yarn is preferably made of cellulose fibers such as natural fibers or regenerated fibers. Preferably, the covering yarns are made of any one of modal fibers, bamboo fibers, seasic fibers and regenerated fibers, or mixed fibers thereof. Preferably, bamboo fiber or rayon-based regenerated fiber is used. In particular, bamboo fiber has a permanent cooling sensation of bamboo itself, has excellent antimicrobial and deodorizing effect, has good blood circulation and has a good effect on newborn (fiber technology and industry) industry / v.7 no.3, 2003, pp.359-363).

The regenerated fiber may be a fiber commonly used in the art, for example, general-purpose viscose rayon, copper-ammonium rayon, cellulose acetate rayon, lyocell, or the like.

The fineness of the covering yarn is preferably 10 to 30 times. If the fineness of the covering yarn is less than 10, the fabric becomes thick and the fabric is inferior. If the fineness is more than 30, the tensile strength is lowered and the productivity is lowered.

The pile yarn can be produced by a conventional twisting yarn or covering manufacturing method. At this time, the file < RTI ID = 0.0 > To 10 TPI (Twist per inch). In addition, it is preferable that the covering yarn is so controlled that the length ratio of the covering yarn to the judging yarn is 1: 1 to 5, more preferably 1: 2 to 3, It is possible to maximize the separation effect between the examination and the covering yarn when it occurs, so that the softness of the towel can be smoothened.

The woven terry fabric is subjected to a primary dyeing step of dyeing the file tilt as in b). In the present invention, it is preferable to use synthetic fibers such as polyester, polyolefin, polyamide, and polyacryl, or composite yarns thereof, so that the primary dyeing step is preferably carried out using a disperse dye.

When the disperse dye is used in the primary dyeing step, since the disperse dye is usually insoluble or hardly soluble in water, a pretreatment step can be preceded in order to facilitate dyeing. In the pretreatment step, a pretreatment liquid containing a scouring agent, a carrier, a dispersing agent, and a pharmaceutical agent including a leveling agent may be used in the dyeing water.

The dyeing water is preferably purified water having a water hardness of 30 to 100 ppm, but is not limited thereto.

The scouring agent removes various impurities attached to the surface of the fiber. Preferably, the scouring agent is a nonionic active agent such as a polyoxyalkylene alkyl ether or the like, or an alkyl benzene sulfonate salt, a sulfuric acid ester salt of an aliphatic alcohol And the like are preferably mixed and used.

The above-mentioned dispersing agent is a medicament for removing various impurities adhering to the surface of the fiber. Preferably, the dispersing agent is sodium naphthalenesulfonate-formalin condensate, sodium alkylnaphthalenesulfonate or formalin condensate thereof, formalin condensate of sodium phenolsulfonate and sodium naphthosulfonate A condensation product, sodium alkyldiphenyl ether disulfonate, sodium ligninsulfonate, a nonionic surfactant polyoxyethylene alkyl (allyl) ether, a mixing preparation of a nonionic surfactant and an anionic surfactant, a sulfonation nonionic surfactant , Water-based dispersants such as sodium polyacrylate, olefin-sodium maleate copolymer, condensed phosphate and carboxymethyl cellulose, alkylbenzene (naphthalene) sulfonate, sodium dioctylsulfone maleate, partial amidation or partial ester of styrene-maleic anhydride copolymer Cargo, fatty acid amides, polyoxyethylene alkylamines, The acid salts or fatty acid salts alkylamine, alkyl 2-level (level 3), and alkyl amine or an amide it is preferable to use a non-aqueous dispersant such as a microporous sleepy.

The carrier serves to increase the water solubility of the fiber by a swelling action that relaxes the fiber structure constituting the examination. In addition, the temperature of the salt solution varies depending on the fiber, but is generally 120 ° C or higher. When the dispersion dye is used, the dye may be infiltrated into the fiber at a temperature higher than the above temperature. However, as in the case of the present invention, there is an advantage that the dyeing process can be effectively performed while using less energy than when a carrier is used.

As the carrier usable in the present invention, it is preferable to use trichlorobenzene, methylnaphthalene, ortho-phenylphenol, N, N-dimethylsulfoxide and N-methyl-2-pyrrolidone.

The above-mentioned retardant is preferably used as an agent for suppressing rapid dyeing in order to prevent staining in the primary dyeing step, such as sodium sulfate, sodium chloride and sodium carbonate.

Further, the pretreatment liquid may further include an acid, which acts to enhance the chromaticity of the dyeing by lowering the pH of the pretreatment liquid. The acid can be those conventionally used in the art.

The pretreatment liquid preferably contains 1 to 2% by weight of a scouring agent, 0.1 to 1% by weight of a carrier, 0.1 to 1% by weight of a dispersant, 1 to 2% by weight of a leveling agent and the balance of water, It is more preferable to further include

The pre-treatment step may be performed by immersing the terry cloth in a bath containing the pretreatment liquid and performing the treatment at 90 to 110 ° C, preferably 95 to 100 ° C for 10 to 30 minutes to shrink the examination and facilitate the penetration of the disperse dye .

As the dyeing method of the primary dyeing step, all conventionally known dyeing methods can be used, and the present invention is not limited thereto.

It is also possible to select the disperse dye from an appropriate database (for example, " color index "). Details and other examples of disperse dyes are described in " Industrial Dyes ", Krause Hughes, Wiley-VCH, Weinheim, 2003, pages 133 to 158. Therefore, they can be selected by referring to them. The disperse dyes may be used in combination of two or more.

In order to impart other functions, the primary salt liquid composition may contain, in addition to the disperse dye, an antioxidant, a pH adjuster, a surface tension reducing agent, a thickening agent, a moisturizer, an oxidizing agent, an antiseptic, a fungicide, an antistatic agent, Or the like may be used. These additives, when used in conjunction with the disperse dye in dyeing, are imparted to the file tilt of the present invention.

The primary salt composition preferably comprises 1 to 3% by weight of a disperse dye, 1 to 5% by weight of an additive and the balance of water.

It is preferred that the primary dyeing step is performed at 90 to 110 ° C, preferably at 95 to 100 ° C, and most preferably at 96 to 98 ° C, not only shrinks the filament slip during the filing but also causes the irregular part So that dyeing becomes more smooth and the fastness is improved. Also, the primary dyeing step is preferably performed for 1 to 2 hours since uniform dyeing proceeds.

When the primary dyeing step is finished, the salt solution is removed from the bath, and the refining / bleaching step is immediately performed in the same bath. The scouring / bleaching step is a common process for forming the fibers forming the bottom portion and the fibers forming the file tilting. Through the above process, it is possible to remove not only unreacted pigment but also absorbability.

The scouring agent used in the scouring / bleaching step may be an inorganic scouring agent or an organic scouring agent commonly used in the art. Examples of the scouring agent include sodium hydroxide (NaOH), sodium carbonate (Na ₂ CO ₃ ) , Sodium bicarbonate (NaHCO ₃ ), sodium sesquicarbonate (Na ₂ CO ₃ NHCO ₃ 2H ₂ O), sodium silicate (xNa ₂ Si ₄ O ₉ + yNa ₂ Si ₂ O ₃ + zH ₂ O), calcium oxide (CaO), and calcium hydroxide (Ca (OH) ₂ ).

Bleaching agents for use in the refining, bleaching step by the action of decomposing the dye material by the oxidation-reduction reaction, such as bleaching powder (Ca (OCl) _2, sodium hypochlorite (NaClO), chlorite soda (NaClO ₂₎ Peroxide bleaching agents such as hydrogen peroxide (H ₂ O ₂ ), sodium peroxide (Na ₂ O ₂ ), sodium perborate (NaBO ₃ .4H ₂ O), potassium permanganate (KMnO ₄ ) ₂ ), sodium sulfite (NaHSO ₃ ), and sodium hyposulfate (Na ₂ S ₂ O ₄ ).

In addition to the above, the treatment liquid composition used in the refining / bleaching step may be further mixed with at least one selected from the group consisting of Ethylene Diamine Tetraacetic Acid (EDTA), Hydroxypolycarboxylic Acid, Amino-methylphosphonic Acid a stabilizer such as a chelating agent, polysilicates, polyacrylate, etc. may be further added, for example, a chelating agent such as methyl phosphonic acid (EDTMP), polycarboxylic acid (Oxalic Acid) or sodium polyphosphate .

The refining / bleaching step is preferably performed at 90 to 98 캜, preferably 95 to 98 캜, and most preferably 96 to 98 캜. If it is out of the above range, the removal of foreign matters, unreacted dyes and the like may not occur properly, and the dyed examination may be discolored through the primary dyeing step.

Preferably, the treatment liquid composition comprises 1 to 5% by weight of a scouring agent, 1 to 5% by weight of a bleach, 0.1 to 5% by weight of an additive, and the balance of water.

After the scouring and bleaching process is completed, a secondary dyeing step is carried out. The secondary dyeing step can be carried out in the same bath as the above-described refining / bleaching step by replacing only the treating solution. Particularly, the method for fabricating a towel according to the present invention comprises dyeing an N / P composite yarn through a disperse dye in a primary dyeing step, and then performing a refining process using caustic soda, a dyeing process suitable for celluloid fibers, It is possible to increase the fastness of the N / P composite yarn by discharging the debris of the disperse dye.

The secondary dyeing step is to dye the bottom portion of the terry cloth in the above step, and it is preferable to use dyeing method and dye of cellulose-based fiber. For example, it is preferable to use any one or two or more dyes selected from direct dyes, sulphide dyes, bat dyes, azo dyes, acid dyes, basic dyes and reactive dyes, preferably using reactive dyes, And it is preferable that the secondary dyeing process can be continuously performed without a water washing process after the scouring / bleaching process and dyeing of various colors is possible. However, in the case of the above-mentioned reactive dyes, there is a large amount of unreacted dyes, and the inflow rate of wastewater reaches 10 to 50% of the total dyes. Therefore, it is preferable to select the dyes considering the fixing ratio with the fibers constituting the bottom portion.

The reactive dye can be applied by controlling the temperature of the salt solution according to the intensity of the reactive dye. The dye is not limited to any dye that can be applied regardless of the dyeing method such as batch dyeing or continuous dyeing.

The reactive dye is composed of a dye matrix and a reactor. Since the adsorption rate largely varies depending on the molecular structure of the dye matrix in the same reactor, the use of a reactive dye combining a dye matrix having excellent fastness to a specific reactor It is good.

As the reactor, it is preferable to have a vinylsulfone-based or triazine-based reactor, which is inexpensive, does not depend on the salt method, forms a stable bond with the fiber, has excellent fastness and uniformity .

All of these dyes have a high fixing rate of 80% or more and excellent wetting fastness, and are suitable for the present invention. Of course, the reactive dyes may be used in combination of two or more.

Further, the secondary salt solution composition containing the reactive dye may further include a mordanting agent and a scouring agent.

The mordant agent promotes color development and dyes pigments to the fibers. The mordants include alum mordants such as alum (aluminum sulfate potassium, AlK (SO ₄ ) ₂ .12H ₂ O), aluminum acetate and aluminum chloride, It is preferable to use sodium mordants such as copper mordants and copper mordants (sodium sulfate) such as copper sulfate and copper sulfate, but it is not limited thereto, and any mordant that is commonly used by those skilled in the art can be used .

The scouring agent acts to remove impurities such that the dye can be well adsorbed to the fibers, and is further classified into a group consisting of alkyl sulfates, alkyl phosphates, alkyl sulfonates, alkyl polyoxyethylene ether sulfonates and alkyl polyoxyethylene ethersulfonates It is preferable to use one or a mixture thereof. However, the present invention is not limited thereto.

The secondary salt composition may comprise 1 to 3% by weight of a reactive dye, 1 to 5% by weight of a mordant, 1 to 5% by weight of a scouring agent and the balance of water.

The secondary dyeing step may be carried out by a method commonly used in the art, and it is preferable that the secondary dyeing step is carried out at 40 to 80 ° C for 1 to 3 hours though it depends on the degree of reactivity.

Further, after the secondary dyeing step is completed, the secondary salt solution composition may be removed from the bath, and then the soaking treatment step may be further performed in the same bath. The soaping process is preferably performed at a temperature of 90 to 110 ° C for 20 minutes to 1 hour to remove remaining unfixed dyes after dyeing.

The soaping liquid composition used in the soaping step may be prepared by adding a soaping agent to ordinary water having the above-mentioned temperature. As the soaping agent, it is preferable to use PROTEPON RSA or PROTEPON NRC from Protecsoria, It does not. In addition, the soaping agent is preferably added in an amount of 1 to 5 g per 1 liter of water because it can prevent the reattachment of the impurities and increase the fastness of the dye while maintaining the constricting power of the metal ions.

When the soaping process is completed, the soaping liquid composition can be removed from the bath and further processed in the same bath, including a softening treatment. The above-mentioned softening treatment is for imparting rebound resilience, smoothness, bulky, and soft touch of a manufactured towel, and the softening treatment can be carried out by a method usually performed in the art. It is preferable that the above-mentioned softening treatment is carried out at 20 to 60 ° C for 10 to 60 minutes.

The softening liquid composition may include a softening agent and water, and the softening agent may be any softening agent conventionally used in the art. As the softening agent, for example, CSE-920 available from Cheongsan Chemtech may be used, but it is not limited thereto and it is preferable to add 1 to 5% by weight of owf.

When the softening treatment is completed, the towel according to the present invention can be manufactured by removing the treatment liquid, moisture, and the like remaining on the terry fabric through water washing and drying process and cutting according to the sales conditions.

The towel according to the present invention may be manufactured by the above method and may include a bottom portion including ground warp and weft yarns and a file warp yarn passing between the weft yarns to form a file.

③ Sweat fastness: AATCC Perspiration Tester (PR-1, Atlas Electric Devices Co., USA) was used according to KS K ISO 105 E04-2005. The alkali sweat solution contained 0.5 g of L-histidine hydrochloride, 5 g of sodium chloride and 5 g of sodium hydrogen phosphate in 1 L of the solution, and the solution was adjusted to pH 8 (solution ratio 50: 1) with 0.1 mol / l sodium hydroxide solution, The sweat solution contained 0.5 g of L-histidine hydrochloride, 5 g of sodium chloride and 2.2 g of sodium dihydrogen phosphate per liter, and the pH was adjusted to 5.5 with 0.1 mol / l sodium hydroxide solution.

Place the test specimens of acid and alkaline artificial perspiration liquid on a smooth dish, pour the solution thoroughly, set it at room temperature for 30 minutes, put the test specimen between two glass plates and put it in the preheated tester. Then, the test piece is dried in a dryer at 37 DEG C for 4 hours. The degree of contamination of each test specimen and the degree of contamination of the attached white cloth were compared with the standard gray color chart for fade color and the standard gray color chart for contamination and the fastness was judged to be 1-5 grade.

(Herbal medicine extract)

Omija, Rhododendron, Rhododendron, Rhizophora, Pseudomonas aeruginosa, Peony root, Pseudomonas aeruginosa, Gingkohwa were sufficiently dried and pulverized to 50 mesh, respectively. 200 ml of ethanol was added thereto, and the mixture was extracted by stirring at room temperature for 24 hours. The extract was centrifuged at 3,000 rpm for 30 minutes and the supernatant was recovered and stored in a -20 ° C freezer until use.

(Example 1)

First, 50 cotton yarns were supplied to the weaving machine as crimper yarn and weft yarn. At this time, the fineness of the slope of the file was 60D / 72F and the composite material was a mixture of polyethylene terephthalate / nylon 6,6 and 70: 30. Also, the fineness of the covering yarn was 10 times, and the material was bamboo fiber.

The weighed terry cloth was charged into a bath containing a primary salt solution composition consisting of 1 wt% of disperse dye (CI Disperse Red 60, LG Chem Co., Ltd.), 1 wt% of carrier (trichlorobenzene) and 98 wt% of water . At this time, the dyeing temperature was 98 占 폚 and proceeded for 1 hour.

The primary dyed terry fabric was discharged from the bath without washing with water and immediately subjected to scouring and bleaching steps. The treatment liquid consisted of 1 wt% of a scouring agent (sodium hydroxide), 1 wt% of a bleaching agent (sodium hypochlorite), and 98 wt% of water.

After the scouring and bleaching step, the treatment liquid was discharged from the same bath and the secondary dye composition was put into the bath to perform the secondary dyeing step. At this time, the temperature of the secondary salt composition was 60 ° C and the treatment time was 1 hour. The secondary salt composition consisted of 1% by weight of a reactive dye (Lanasol CE, CIBA Specialty Chemicals) and 99% by weight of water.

After completion of the dyeing process, the secondary salt composition was removed in the same bath, and the soaping liquid to which 1 wt% of a soaping agent (PROTEPON RSA, Protec SCORA) was added was added thereto and the reaction was carried out at 98 캜 for 30 minutes.

After the soaping process, the soaping liquid was removed in the same bath, and the supernatant containing 1% owf of softening agent (CSE-920, Cheungsan Chemtex Co.) was added thereto and the mixture was stirred at 40 ° C for 30 minutes.

After the soaping process, the sample was sufficiently washed with water and dried to prepare a specimen. The feel and fastness of the specimen were measured and are shown in Table 1 below.

(Example 2)

A specimen was prepared in the same manner as in Example 1, except that the fineness of the examination constituting the file inclination was changed to 100 D / 72 F and the fineness of the covering yarn was changed to 20 facet. The feel and fastness of this specimen were measured and reported in Table 1 below.

(Example 3)

Specimens were prepared in the same manner as in Example 1, except that the fineness of the examination constituting the file inclination was changed to 160 D / 72 F, and the fineness of the covering yarn was changed to the number of 30 facings. The feel and fastness of this specimen were measured and reported in Table 1 below.

(Comparative Example 1)

A specimen was prepared in the same manner as in Example 2 except that the primary dyeing step was carried out at a temperature of 85 캜 in the primary dyeing step. The feel and fastness of this specimen were measured and reported in Table 1 below.

(Comparative Example 2)

A specimen was prepared in the same manner as in Example 2 except that the fineness of the covering yarn was changed to the number of the cotton yarn on the 5th side. The feel and fastness of this specimen were measured and reported in Table 1 below.

(Comparative Example 3)

Specimens were prepared in the same manner as in Example 2 except that the fineness of the examination was changed to 200 D / 72F. The feel and fastness of this specimen were measured and reported in Table 1 below.

As shown in Table 1, in Comparative Example 1 in which the temperature was set to be lower in the primary dyeing step, the overall fastness of the dye was poor as compared with the Examples. In the case of Comparative Examples 2 and 3 in which the fineness of the filament slip and the covering fineness constituting the filament slip were different, the fastness values were similar to those of the examples but they did not show satisfactory results in the sensory test.

(Example 4)

After washing and drying of the specimen prepared in Example 2, the herbal extract was composed of the treatment liquid and coated on the surface of the specimen. At this time, extracts of Chinese medicinal herbs were added with owf, 3, 5, respectively. The treatment solution was composed of 10% of 1,2,3-propanetricarboxylic acid (Aldrich) owf as a binder and 3% of sodium hypophosphite (Aldrich) owf as a catalyst.

The herbicide treatment solution was prepared by immersing the specimens prepared in the bathtub. The temperature of the treatment solution was 50 ° C and the immersion time was 5 minutes. The immersed specimens were washed thoroughly and treated with 0.1M NaOH solution for 5 minutes at room temperature to convert the carboxyl groups of unreacted 1,2,3-propanetricarboxylic acid to carboxylate. The antibacterial properties of the prepared specimens were measured.

As a result, Example 4, in which the extract of herbal medicines were treated on the surface of the test specimen, showed that the reduction rate of Staphylococcus aureus, pneumococcus and feline calicivirus was 99.9%. Further, as a result of sensory tests such as fragrance and feel through the same sensory test, the sensation was the same as in the other examples with a touch feeling of 5, and an overall preference including aroma showed an average of 4.8, which was even better than the comparative example.
