Description

TECHNICAL AREA

The following disclosure relates to a process for producing a multi-layered towel having a terry structure using a bamboo fiber and a multi-layered towel made therewith.

BACKGROUND

In general, a towel used to remove water or sweat generated after bathing or exercising is made of cotton fibers or the like to rapidly absorb water remaining on the skin or remaining perspiration without damaging it Irritate the skin.

However, in the case of using 100% cotton fiber, there is a limitation on the absorbency, and there are drawbacks that the hygroscopicity after long-term use may decrease and the towel becomes stiff, whereby it becomes, at the time of contact with the skin Foreign body is felt. In order to overcome these drawbacks, there has been developed a method of making a towel having a pile formed therein by using a hemp yarn in Korean Patent No. 10-1203525 but there were disadvantages in that the elasticity was insufficient, and stiffness was felt due to properties of the hemp yarn itself, and to solve these problems, a large amount of fabric conditioner was needed.

In order to overcome the disadvantages as described above, a towel was made using synthetic fiber or synthetic fiber / natural fiber blended yarns as well as natural fibers. A high absorption toweling fabric having pile warps inserted into the base fabric using a polyester / nylon split microfiber is disclosed in U.S. Pat Korean Patent Publication No. 10-2004-0016620 disclosed. However, in the case where a loop or curl is formed using the microfiber, the microfiber tends to adhere to skin, so that no gentle touch is obtained. In addition, in a terry cloth using the synthetic fiber, it may be difficult to dye split yarn used as a pile at the time of performing a dyeing process after the production of the fabric, and color fastness may be lowered, which may cause severe discoloration.

Therefore, development of a terry cloth which maintains a gentle touch and high hygroscopicity and which has excellent coloring properties has been demanded.

In a general aspect, there is provided a method of making a towel using terry cloth, the method comprising:

• a) a terry fabric manufacturing step of providing a pile warp made by twisting or twisting core yarn and cover yarn or covering the core yarn with the cover yarn between weft yarns to form a loop during weaving of a lower portion including ground warp and weft yarn;
• b) a primary dyeing step of dyeing the pile warp in the terry cloth with a disperse dye,

• d) a secondary dyeing step of dyeing the lower portion in the terry cloth of step c) with a reactive dye, wherein steps b) to d) are performed in the same bath and the core yarn and cover yarn are spaced apart to thereby be in the primary Staining step to be separated from each other.

In this case, the pile yarn can be obtained by twisting and twisting the core yarn made of a polyester / polyamide composite fiber and the cover yarn made of bamboo fiber or a viscose-based regenerative fiber at a volume ratio of 1: 1.

In another general aspect, a towel is provided comprising ground warp yarns and weft yarns, and pile warps passing through the weft yarns to form the pile, and which are formed by twisting the core yarn and the cover yarn and then twisting them together, or by Core yarn is covered with the cover yarn, the base warp yarns and the weft yarns may have a cotton yarn number 20-40, the core yarn of Florkette a fineness of 60-160 D / 72 F and the cover yarn may have a fineness of a cotton yarn number 10-30.

Hereinafter, the manufacturing method of a towel having a multi-layered structure and the multi-layered towel according to the present invention will be described in detail.

In the method of manufacturing a towel according to the present invention, first, the terry cloth is prepared by providing a pile warp between weft yarns to form a loop at the time of weaving the lower portion including the ground warp and the weft as in the step a).

In the present specification, the term "terry cloth", which is referred to as Florkettengewebe means a fabric which is obtained by a lower portion (base fabric) is woven using a kind of warp and weft and separated the Florkette is arranged to a Flor or a tassel to form on the fabric surface. In more detail, the terry fabric means a multi-layered pile warp fabric in which loops or curls are formed using a special warp yarn called a terry pile.

As the base warp and weft provided in step a) of a weaving section, a natural fiber generally used in the art can be provided. Preferably, all of the cotton fiber, hemp fiber, wool fiber, regenerated fiber made by spun-splicing or melt-spinning, and the cellulose-based fiber may be used. Among these, the cotton fiber may be most preferable because the cotton fiber, which is a natural fiber, is environmentally friendly and has no negative influence on the skin.

It may be advantageous in making a towel and, to provide good tactile sensation of the manufactured towel, that the fineness of the base warp and weft is a 20 to 40 cotton count.

The pile warp obtained by twisting fibers made of different materials may contain the core yarn and the cover yarn wound in a spiral shape around the core yarn, or may be formed of twisted yarn in which the core yarn and the cover yarn as in 2 or 3 shown mixed.

As a method for producing the pile warp, a general twisting method or covering method can be used. However, in terms of the tensile strength at the time of weaving, it may be preferable that the core yarn and the cover yarn are twisted and twisted at a volume ratio of 1: 1.

The pile warts according to the present invention may be spaced apart from each other to be separated from each other in the primary dyeing step. The separation as described above is produced by shrinking the pile warps according to a temperature of a primary dyeing solution composition used in the primary dyeing step. The reason is that the tension applied in a weave color direction in a weaving process is removed by the temperature of the primary dyeing solution composition to cause the shrinkage. In addition, the materials of the core yarn and the cover yarn which form the pile warps are different from each other, so that the separation can be produced.

The core yarn serves to maintain a volume or shape of the pile warps, and the type of core yarn is not limited as long as it is generally used in the art. Preferably, the core may be selected from any of polyester, polyolefin, polyamide and polyacrylic material, or a blend fiber thereof, and it is most preferred that the core yarn be made of a mixed fiber of polyamide and polyester, especially a polyamide / polyester composite yarn (N / P composite yarn) which has been spun by the same spinning process, since coloring agents capable of coloring the lower portion and the pile warps face each other in a single bath at the time of performing of the dyeing process.

In the present specification, the term "N / P composite yarn" is a type of special yarn and a fiber prepared by spun nylon and polyester through the same spinneret. In this case, a component may be dissolved or divided into ultrafine filaments to be used, and the core yarn and pile yarn of the pile warp according to the present invention may be spaced apart from each other to be spaced from each other in the primary dyeing step. The reason is that the N / P composite yarn constituting the core yarn has a higher heat shrinkage degree than that of the bamboo fiber constituting the cover yarn.

In the case where the core yarn is the N / P composite yarn, the core yarn may contain 70 to 90% by weight of polyester and 30 to 10% by weight of polyamide.

In addition, as the core yarn, any one of a spun yarn and a filament yarn may be used. In the case where the core yarn is a filament yarn, a shape of a cross section thereof is not limited, but it is preferable that the cross section is a triangular shape (Δ) or a shape of the letter Y, since moisture in this case is fast and can be effectively absorbed and dried by a capillary phenomenon.

Preferably, the core yarn may have a fineness of 60 to 160 D / 72 F. In the case where the fineness is smaller than 60 D / 72 F, a yarn cutting ratio is increased at the time of making a towel, and in the case where the fineness is larger than 160 D / 72 F, the fiber becomes thick, so that the web properties are significantly reduced.

The cover yarn serves to have effects of the pile warp and of the towel which will be produced, and visual or tactile impressions of the cover yarn can be exhibited to the outside as the whole effect of the composite yarn. The cover yarn may be made of cellulose-based fibers such as natural fibers, regenerated fibers or the like, and preferably any one selected from modal fiber, bamboo fiber, sisal fiber and regenerated fiber, or a mixed fiber thereof; most preferably, the bamboo fiber or viscose-based regenerated fiber can be used. In particular, the bamboo fiber has a permanent cooling effect of the bamboo tree itself, excellent antibiotic and deodorizing effects and effects of improving blood circulation and metabolic processes ( Fiber Technology and Industry, Vol. 7, No. 3, 2003, pp. 359-363 ) on.

As the regenerated fiber, fibers generally used in the art may be used, for example, viscose filaments, copper ammonium filaments, cellulose acetate filaments, lyocell, and the like.

The fineness of the cover yarn can be a cotton yarn number of 10-30. In the case where the fineness of the covering yarn is smaller than the cotton yarn number of 10, the fiber becomes thick, so that weaving properties may be deteriorated, and in the case where the fineness is larger than that of cotton yarn number of 30, the fiber may be Tensile strength can be reduced, so that the productivity is reduced.

The pile warps can be made by a general method of making a twisted / twisted yarn or cover yarn. In this case, the pile warp may be a twisted yarn having a degree of twist of 6-10 Vpf (twist per foot). In addition, an aspect ratio of the cover yarn to the core yarn may be 1: 1-1: 5, and it may be more preferable that the aspect ratio is kept at 1: 2-1: 3. The reason is that the separation effect between the core yarn and the cover yarn can be maximized when heat-induced shrinkage of the pile warps in the primary dyeing step is generated, so that the touch feeling of the towel can be further softened.

The woven terry cloth may be subjected to the primary dyeing step of dyeing the pile warps as in step b). According to the present invention, since a base fiber made of polyester, polyolefin, polyamide, polyacrylic and the like, or a composite yarn thereof, can preferably be used as the pile warp, the primary dyeing step can be carried out using the disperse dye.

During use of the disperse dye in the primary dyeing step, a pre-treatment step may be performed in advance to facilitate dyeing because the disperse dye is generally insoluble or sparingly soluble. In the pretreatment step, a pretreatment solution in which an agent containing a scavenger, a carrier, a dispersant and an inhibitor are mixed with water for dyeing can be used.

The dyeing water, which is purified water, may have, but is not limited to, a water hardness of 30 to 100 ppm.

The rinsing agent is used to remove various impurities adhering to the surface of the fiber, and an anionic surfactant such as polyoxyalkylene alkyl ether or the like or a mixture of the anionic surfactant such as alkylbenzenesulfonates, sulfonic acid ester salts of aliphatic alcohol or the like can be preferably used as the rinsing agent.

The dispersant is a means for removing various impurities adhering to the surface of the fiber, and an aqueous dispersing agent such as sodium naphthalenesulfonate formalin condensates, sodium alkylnaphthalenesulfonates or a condensate thereof with formalin, a condensate of sodium phenolsulfonate and sodium naphthalenesulfonate with formalin, sodium alkyldiphenyl ether disulfonate, sodium lignosulfonate, nonionic surfactant A substance such as polyoxyethylene alkyl (allyl) ether, a mixture of nonionic surfactants and anionic surfactants, sulfonated nonionic surfactants, sodium polyacrylate, an olefin sodium maleate copolymer, condensed phosphate salt, carboxymethyl cellulose and the like, and a nonaqueous dispersant such as alkylbenzene (U.S. Naphthalene) sulfate salt, sodium dioctylsulfone maleate, partial amides or partial esters of a styrene maleic anhydride copolymer, a fatty acid amide, polyoxyethylene alkyl lamin, an actetate salt or a fatty acid salt of alkylamine, secondary (tertiary) alkylamine or amide, alkylimidazoline and the like can be preferably used.

The carrier serves to increase the water solubility of the fiber by a swelling process of relaxing a structure of the fiber forming the core yarn. In addition, at the time of using the general disperse dye, a temperature of a dye liquid corresponding to the fiber is different, but may be 120 ° C or more. The reason is that at the above-mentioned temperature or more, a hollow is formed in the fiber to create a state in which the dye can penetrate. However, in the case of using the carrier, as in the present invention, a dyeing process can be effectively carried out although a small amount of energy is used.

As a carrier capable of being used in the present invention, trichlorobenzene, orthophenylphenol, N, N-dimethylsulfoxide, N-methyl-2-pyrrolidone and the like can be preferably used.

The retarder is an agent which suppresses rapid dyeing to prevent greasing in the primary dyeing step, and sodium sulfate, sodium chloride, sodium carbonate and the like can be preferably used.

Further, the pretreatment solution may further contain an acid, the acid serving to further reduce the pH of the pretreatment solution to increase chroma of the dyeing. As acid, acids commonly used in the art may be used.

The pretreatment solution may contain 1 to 2% by weight of the rinse, 0.1 to 1% by weight of the carrier, 0.1 to 1% by weight of the dispersant, 1 to 2% by weight of the delay agent, and the remainder water, and may be further 0.01 to 0.1 wt.% Of the acid.

It is preferable that the pretreatment step is carried out by dipping the terry cloth in a bath filled with the pretreatment solution at 90 to 110 ° C, preferably 95 to 100 ° C for 10 to 30 minutes, since the core yarn can be shrunk and the disperse dye in this case can easily penetrate.

As a dyeing method in the primary dyeing step, any of the existing dyeing methods known in the art may be used, and the invention is not limited thereto.

As the disperse dye which is a dye having one or a plurality of multichromopores, azo dyes, anthraquionone dyes, quinophaton dyes, naphthalimide dyes, naphthoquinone dyes, nitro dyes and the like can be used. For example, CI Disperse Yellow 3, CI Disperse Yellow 5, CI Disperse Yellow 64, CI Disperse Yellow 160, CI Disperse Yellow 211, CI Disperse Yellow 241, CI Disperse Orange 29, CI Disperse Orange 44, CI Disperse Orange 56, CI Disperse Red 60, CI Disperse Red 72, CI Disperse Red 82, CI Disperse Red 388, CI Disperse Blue 79, CI Disperse Blue 165, CI Disperse Blue 366, CI Disperse Blue 148, CI Disperse Violet 28 and CI Disperse Green 9.

In addition, the disperse dye can be selected from a suitable database (for example, "Color Index"). A detailed description of other examples of the disperse dyes is described in ⌋industrial dyes⌋ ( Hunger Kraus, Wiley-VCH, Weinheim, 2003, pages 133-158 ). Therefore, the dye can be selected by referring to Examples. In addition, a combination of at least two kinds of the disperse dye can be used.

Further, in the primary coloring solution composition to provide other functions, additives such as an anti-oxidizing agent, a pH adjusting agent, a surface tension reducing agent, a thickening agent, a humectant, a color improving agent, an antiseptic agent, an antifungal agent, an antistatic agent Metal ion blocker, an anti-reducing agent and the like are added to the disperse dye. These additives may be used together with the disperse dye at the time of dyeing to impart other functions to the pile warp according to the present invention.

The primary dyeing solution composition may contain 1 to 3% by weight of the disperse dye, 1 to 5% by weight of the additive, and the remainder water.

The primary dyeing step may preferably be carried out at 90 to 110 ° C, more preferably 95 to 100 ° C, most preferably 96 to 98 ° C. In this case, the core yarn of the pile warp can be shrunk, and the support can expand an amorphous portion of the filament forming the core yarn, so that the dyeing can be easily performed, and color fastness can be improved. In addition, it is preferable that the primary dyeing step is carried out for 1 to 2 hours, since dyeing is uniformly performed in this case.

When the primary dyeing step is completed, the dyeing solution is removed from the bath, and the rinsing and bleaching step is carried out in the same bath. The rinse and bleach step is a conventional process for the fiber that forms the lower portion and the fiber that forms the pile warp and foreign materials and unreacted pigments can be removed, and absorption can be improved by this process.

As the rinsing agent used in the rinsing and bleaching step, an inorganic or organic rinsing agent generally used in the art can be used. For example, 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), calcium hydroxide (Ca (OH) ₂ ) or the like.

A bleaching agent used in the rinsing and bleaching step decomposes pigments by an oxidation-reduction reaction. For example, a chlorine bleach such as bleach powder (Ca (OCl) ₂ ), sodium hypochlorite (NaClO), sodium chlorite (NaClO ₂ ) or the like, a peroxide-based bleach 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 ) and the like, a sulfur oxide-based bleaching agent such as sulfur dioxide (SO ₂ ), sodium bisulfite (NaHSO ₃ ), sodium hydrosulfite (Na ₂ S ₂ O ₄ ) and the like.

In addition, in a treatment solution composition used in the rinsing and bleaching step, a chelating agent such as aminopolycarboxylic acid (e.g., ethylenediaminetetraacetic acid; EDTA), hydroxypolycarboxylic acid (e.g., citric acid), aminomethylphosphonic acid (e.g., ethylenediamine tetramethylphosphonic acid, EDTMT), polycarboxylic acid (e.g. Oxalic acid), sodium polyphosphate (e.g., sodium hexametaphosphate) or the like, or a stabilizer such as polysilicates, polyacrylates or the like can be further added.

The rinse and bleach step may be carried out at 90 to 98 ° C, preferably 95 to 98 ° C, most preferably 96 to 98 ° C. In the case where the temperature is out of the range, it may happen that the foreign matters, unreacted dye or the like is not adequately removed, and the core yarn dyed in the primary dyeing step may then be decolorized.

The treatment solution composition may contain from 1 to 5% by weight of the rinse aid, from 1 to 5% by weight of the bleach, from 0.1 to 5% by weight of the additive, and the remainder water.

After the rinse and bleach process is complete, the secondary dyeing step can be performed. The secondary dyeing step may also be carried out in the same bath after only exchanging the treating solution as in the rinsing and bleaching step. In particular, in the method of manufacturing a towel according to the present invention, after the N / P composite yarn is dyed with the disperse dye in the primary dyeing step, waste of the disperse dye is discharged while being subjected to the rinsing process using sodium hydroxide, a dying process is suitable for the cellulose fiber and a variety of post-treatment processes, so that the color fastness of the N / P composite yarn can be increased.

The secondary dyeing step serves to dye the lower portion of the terry cloth fabric in this step, and a dyeing method and a dye for cellulose fiber can be preferably used. For example, one or at least two dyes selected from direct dyes, sulfide dyes, vat dyes, azo dyes, acid dyes, basic dyes, and reactive dyes can be used. In particular, a reactive dye may be preferable, since the color fastness may be excellent, the secondary dyeing process may be carried out continuously without performing a washing process after the rinsing and bleaching process, and dyeing in different colors may be performed. However, in the case of the reactive dye, it is preferable that the dye is selected in consideration of a fixing rate with the fiber constituting the lower portion, because a large amount of undyed dyes may remain, and a dirty water influx of 10 to 15% of the entire dye can reach.

The reactive dye may be used while adjusting a temperature of the dyeing solution according to the degree of reactivity, and the kind of the dye is not limited as long as the dye can be used independently of the dyeing method such as a batch dyeing method, a continuous dyeing method and the like.

The reactive dye is formed from a chromogen and a reactive group. Since an absorption rate corresponding to the molecular structure of the chromogen can be significantly changed even in the case where the same reactive group exists, a reactive dye which can generally be used is obtained by combining a chromogen having color fastness to a specific reactive group, are preferably used.

It is preferable that the reactive group is a vinylsulfone-based or triacin-based reactive group because the cost is cheap and the dyeing method is not limited, the reactive group is stably bonded to the fiber, and color fastness and flatness are excellent.

Examples of the reactive dye used in the present invention may include Lanasol CE, Yellow light, Orange light, Blue light, Navy light, Red light, Rose light, Lemon light, Sky light, Cibacron FN, Red FN-3G, Red FN-G and Cibacron IS (CIBA specialty chemicals); Blue P-NFB Liquid 50, Yellow P-N3R Liquid 33 and Red P-4BN Liquid 25 (Nippon Kayaku); Sumifix HF Type (Sumitomo Chemical Co., Ltd); Srius plus, Realan, Reanova CA (DyStar); Remazol RU-N (Mitsubishi Kasei Hoechst Co., Ltd.); Procion CX (Zeneca); Optizal-based dyes (Clariant Co.), and the like. All of these dyes have a high fixing rate of 80% or more and excellent color fastness to humidification, so that these dyes may be suitable for the present invention. A combination of at least two types of reactive dyes can be used.

In addition, the secondary dyeing solution composition containing the reactive dye may further comprise a mordant and a rinsing agent.

As the mordant serving to promote dyeing and dye fixing of the dye to the fiber, aluminum mordants such as alum (potassium aluminum sulfate, AlK (SO ₄ ) ₂ .12H ₂ O, aluminum acetate, aluminum chloride and the like, copper mordants such as copper acetate, copper sulfate, may preferably be used and the like, sodium stain such as sodium sulfate anhydrate and the like can be used, but the present invention is not limited thereto, and any stain may be used as long as it is generally used by those skilled in the art.

The rinsing agent serves to remove impurities so as to allow the dye to be absorbed well in the fiber, and one selected from a group consisting of alkylsulfate, alkylphosphate, alkylsulfonate, alkylpolyoxyethylene ether sulfonate and alkylpolyoxyethylene ether phosphate or a mixture thereof can be preferably used but the present invention is not limited thereto.

The secondary dyeing solution composition may be adapted to contain 1 to 3% by weight of the reactive dye, 1 to 5% by weight of the mordant, 1 to 5% by weight of the flushing agent and the remainder water.

The secondary dyeing step may be carried out by a method generally used in the art at 40 to 80 ° C for 1 to 3 hours, but the temperature and the time may be changed according to the degree of reactivity.

In addition, according to the present invention, after the second dyeing step is completed, the secondary dyeing solution composition is removed from the bath, and then a soaping step can be further carried out in the same bath. The soapy process is a process for removing unfixed dye which remains after dyeing, and may be carried out at 90 to 110 ° C for 20 minutes to 1 hour.

A soap solution composition used in the soaping process can be prepared by injecting a soaping agent into general water at the above-mentioned temperature, and a preferable example of the soaping agent may include PROTEPON RSA, PROTEPON NRC (Protex Korea, Co.) or the like but is not limited to this. In addition, the soaping agent is added in an amount of 1 to 5 g based on one liter of water, which is preferable from the viewpoints of preventing re-adhering of the impurities while retaining a blocking power of metal ions to enhance color fastness of the dye ,

After the soapy process is completed, the suds solution composition is removed from the bath, and a fabric softener treatment can be further carried out in the same bath. The softener treatment which serves to impart resilience, softness, voluminous property, smoothness and soft feel to the manufactured towel may be accomplished by a method generally used in the art. In addition, the softener treatment can be treated by treatment of the towel with a fabric softener solution composition at 20 to 60 ° C for 14 to 60 minutes.

The fabric softener solution composition may be configured to contain a fabric softener and water, and any fabric softener may be used as long as it is commonly used in the art. As the softener, for example, CSE-920 (Chengsan Chem Tech Co., Ltd.) can be used, but the present invention is not limited thereto. The softener can be added in an amount of 1 to 5% based on the weight of the fiber (gdf).

After the softener treatment is completed, the treatment solution, moisture and the like remaining in the terry cloth are removed by a washing and drying process, and the terry cloth is cut according to the conditions for sale, whereby the towel according to the present invention is produced ,

The towel according to the present invention, which is produced by the above-mentioned method, may be configured to include the lower portion comprising ground warp yarn and weft yarn and pile warps passing through the weft yarns to form the pile. In this case, as described in the method for producing a towel, the base warp and the weft may have a cotton yarn number of 10 to 16, core yarn of the pile warp may have a fineness of 60 to 160 D / 72 F, and the cover yarn may be a fineness a cotton yarn number of 10 to 30 have.

In addition, the method of manufacturing a towel according to the present invention may further include a process of attaching medicinal herbal extracts to surfaces of the lower portion and the pile warp. In this case, the attaching process may be performed after the softener treatment and the washing and drying process are completed.

The herbal medicinal extracts according to the present invention can be obtained from any of Schizandra chinensis fruit, Coptis chinensis, Houttuynia cordata thunb, Anemarrhenae rhizoma, Taraxaci herba, Paeonia lactiflora, Forsythia viridissima, Lonicera japonica or a mixture thereof. These medicinal herbs can impart the characteristic natural aroma of the medicinal herb to the manufactured towel and minimize irritation to the skin. In addition, a stronger antibiotic effect can be obtained along with the antibiotic effect of bamboo fiber.

As a method of extracting the medicinal herbal extracts, a general extraction method, for example, a method of heating or using a solvent, may be used, and the medicinal herbal extracts may be condensed to be used as needed.

To apply the medicinal herbal extracts to the surface of the fiber, a binder can be used. The binder is not limited as long as the binder is hydrophilic and does not unduly deteriorate the physical properties of the towel to be made.

As the binder, polycarboxylic acids such as aliphatic polycarboxylic acids, alicyclic polycarboxylic acids, aromatic polycarboxylic acids, saturated aliphatic dicarboxylic acids, unsaturated aliphatic dicarboxylic acids, aromatic dicarboxylic acids, alicyclic dicarboxylic acids or the like can be preferably used, and glycol polymers such as polyethylene glycol, polypropylene glycol or the like can be used.

As a method for applying the medicinal herb, a method generally used in the art, for example, a dipping method, a spraying method, a coating method, or the like, may be used, and among these methods, the dipping method may be preferable.

The medicinal herbal extracts and the binder may be applied in a liquid phase containing a solvent. In this case, add 1 to 10% (gdf) of medicinal herbal extracts and 5 to 20% (gdf) of the binder. Further, as the solvent, a general solvent capable of dissolving both the binder and medicinal herbal extracts may be used, but the present invention is not limited thereto.

BENEFICIAL EFFECTS

In a towel according to the present invention which has a multi-layered structure using a pile warp with a composite yarn structure, an inner layer structure in which a pile layer of the multi-layer structure is separated can increase a water absorbency, which is an advantage of the N / P composite yarn, and an outer structure can improve softness through a viscose-based regenerated fiber as well as the bamboo fiber, so that more excellent absorbency and softness can be obtained as compared with the existing towel.

In addition, since the processing and dyeing steps are performed in the same bath, dyeing in different colors can be performed in the same process without mutual interference between dyes, so that power consumption and manufacturing cost can be reduced, and the after-treatment process can be simplified.

Furthermore, the medicinal herbal extracts are attached to the fiber so that bacterial proliferation caused by using the towel can be suppressed.

A sensory analysis for evaluating the touch was performed by 20 trained persons for sensory analysis, and the touch was scored based on a 5-point scale according to the preference, and an average value of the scored results was recorded.

(Color fastness)

• (1) Color fastness to light: The towels were illuminated with a standard arc fading hours lamp of 20 hours using a fade-o-meter (Color fastness test method: Carbon arc method, USA) based on KS K 0700 illuminated. A degree of fading in a sample (40 mm x 100 mm) after the illumination was complete was compared with KS K 0911 for fading a standard blue colored fabric (200 g of plain weave fabric per 1 m ² dyed with a dye). compared and rated on a scale. Color fastness to light was measured on a scale of 1 to 5.
• (2) Color Fastness to Washing: Launder-O-Meter (Model: M228AA, SDL Atlas, USA) was based on KS K ISO 105-006-2007 used. To obtain a frictional effect, were stainless Beads were used, and 4 g of a standard detergent was dissolved in 1 liter of water, and rinsing was carried out twice using 100 ml of water at 40 ° C for one minute. Fading of colors and six types of discoloration of adjacent tissues were finally evaluated using a gray scale.
• (3) Color fastness to perspiration: An AATCC Perspiration Tester (PR-1, Atlas Electric Devices Co., USA) was based on KS K ISO 105 E04-2005 used. An alkaline sweat was prepared by adding 0.5 g of L-histidine hydrochloride salt, 5 g of sodium chloride and 5 g of sodium phosphate to one liter of solution and adjusting the pH to 8 (50: 1 solution ratio) using sodium hydroxide (0.1 mol / l) and acid sweat was prepared by adding 0.5 g L-histidine hydrochloride salt, 5 g sodium chloride and 2.2 disodium hydrogen phosphate in one liter of solution and adjusting the pH to 5.5 using sodium hydroxide (0.1 mol / l).

The samples for the acidic and basic perspiration were provided on a dish with a flat bottom, and the solution was poured into the dish to make the sample completely wet, and then allowed to stand at room temperature for 30 minutes. Then the samples were each placed in two glass plates to be inserted into a tester. Next, the samples were dried for 4 hours using a dryer at 37 ° C. A degree of fading of each of the samples and a degree of discoloration of adjacent tissues were compared with a gray scale for evaluating the discoloration of a gray scale to evaluate a change in color to evaluate the color fastness on a scale of 1 to 5.

(Medicinal herbal extracts)

Schizandra chinensis fruit, Coptis chinensis, Houttuynia cordata thunb, Anemarrhenae rhizoma, Taraxaci herba, Paeonia lactiflora, Forsythia viridissima and Lonicera japonica were sufficiently dried, each at a mesh size of 50 grated. Each 200 ml of ethanol was added thereto and stirred for 24 hours at room temperature, followed by extraction. After centrifuging with the extracted solution at 3000 rpm for 30 minutes, the supernatant was recovered and stored in a freezer at -20 ° C before being used.

[Example 1]

First, cotton fiber having a cotton yarn number of 50 was fed to a weaving machine as a base warp and weft, and a separate pile warp was fed, thereby weaving a towel. In this case, the core yarn forming the pile warp had a fineness of 60 D / 72 F and was made of composite yarn in which polyethylene terephthalate and nylon 6.6 in a ratio of 70:30 as in 2 shown were mixed. In addition, a fineness of cover yarn was a cotton yarn number 10 and a material thereof was bamboo fiber.

The woven terry cloth was filled in with a primary dyeing solution composition formed of 1% by weight of disperse dye (CI Disperse Red 60, LG Chem. Ltd.), 1% by weight of a carrier (trichlorobenzene), and 98% by weight of water Bath introduced, and a dyeing time was 1 hour.

The primary dyeing solution composition was drained from the bath, and a rinse and bleach step was performed directly with the primary dyed terry cloth without washing. At this time, a temperature of a treatment solution was 98 ° C, a treatment time was 30 minutes, and the treatment solution was constituted by 1% by weight of a rinsing agent (sodium hydroxide), 1% by weight of a bleaching agent (sodium hypochlorite), and 98% by weight of water ,

After the rinse and bleach step was completed, the treatment solution was drained from the bath and a secondary dyeing solution composition was introduced into the bath to perform a secondary dyeing step. At this time, a temperature of the secondary dyeing solution composition was 60 ° C, a treatment time was 1 hour, and the secondary dyeing solution composition was formed from 1% by weight of a reactive dye (Lanasol CE, CIBA Specialty Chemicals) and 99% by weight of water. When the dyeing process was completed, the secondary dyeing solution composition was removed from the bath, and a soap solution containing 1% by weight soaping agent added thereto (PROTEPON RSA, Protex Korea, Co.) was placed in the same bath to effect a soaping process at 98 ° C for 30 minutes.

After the soaping process was completed, the soap solution was removed from the bath and a fabric softener solution containing 1% (gdf) softener added thereto (CSE-920, Chengsan Chem Tech Co., Ltd.) was incorporated into the same bath to provide a fabric softening process at 40 ° C for 30 minutes.

After the fabric softening process was completed, the terry cloth was sufficiently washed and dried to prepare a sample, and the touch and color fastness of the sample were measured. The results obtained are shown in the following Table 1.

[Example 2]

A sample was prepared by the same method as in Example 1 except that the fineness of the core yarn constituting the pile warp was changed to 100 D / 72 F, and the fineness of the cover yarn was changed to cotton yarn number 20. The touch and color fastness of the sample were measured, and the results obtained are shown in the following Table 1.

[Example 3]

A sample was prepared by the same method as in Example 1 except that the fineness of the core yarn constituting the pile warp was changed to 160 D / 72 F, and the fineness of the cover yarn was changed to cotton yarn number 30. The touch and color fastness of the sample were measured, and the results obtained are shown in the following Table 1.

Comparative Example 1

A sample was prepared by the same method as in Example 2 except that a primary dyeing step was carried out in a state in which the temperature of the primary dyeing solution was 85 ° C. The touch and color fastness of the sample were measured, and the results obtained are shown in the following Table 1.

(Comparative Example 2)

As shown in Table 1, it is to be noted that the overall color fastness of the sample in Comparative Example 1 in which the temperature was set low in the primary dyeing step was poor compared with that of Examples. Further, in Comparative Examples 2 and 3, in which the finenesses of the core yarn and the cover yarn constituting the pile warp were different, the color fastness was similar to that in the examples, but no satisfactory results were obtained in the sensory analysis.

[Example 4]

After the sample prepared in Example 2 was washed and dried, a treatment solution consisting of medical herbal extracts was coated on a surface of the sample. In this case, as the medicinal herbal extracts, 3% (gdf) of Schizandra chinensis fruit, Coptis chinensis, Houttuynia cordata thunb, Anemarrhenae rhizoma, Taraxaci herba, Paeonia lactiflora, Forsythia viridissima and Lonicera japonica were extracted and added respectively. 10% (gdf) of 1,2,3-propanetricarboxylic acid (Aldrich) as a binder and 3% (gdf) of sodium hydrophosphite (Aldrich) as a catalyst were added thereto, forming the treating solution.

The sample was dipped in a bath filled with the medical herbal treatment solution to thereby be coated with the medicinal herbal treatment solution. At this time, a temperature of the treatment solution was 50 ° C, and a dipping time was 5 minutes. After immersion was completed, the sample was sufficiently washed, and to convert carbon groups of unreacted 1,2,3-propanetricarboxylic acid to carboxylate, the sample was treated in aqueous 0.1 M NaOH solution at room temperature for 5 minutes. An antibiotic effect of the sample was measured.

As a result, in Example 4, Staphylococcus aureus, Pneumococcus, and Feline calicivirus were reduced by 99.9%, in which the surface of the sample was treated with the medicinal herb extract. Therefore, it should be noted that the antibiotic effect was excellent. In addition, a sensory analysis for judging aroma, touch and the like was performed by the same persons for the sensory analysis. As a result, the touch was rated as 5, which was the same value as that in the other examples, and the overall preference including the flavor was rated at 4.8 on average, which was more excellent than in the comparative examples.
