Manufacturing method of towel using wet heating fiber {MANUFACTURING METHOD OF TOWEL　WITH HYGROSCOPIC HEAT-RELEASING FIBER}

The present invention relates to a method of manufacturing a multilayer towel having a terry structure using wet heating fibers and a multilayer towel manufactured therefrom.

Recently, in the textile industry, research on complex high-functional fibers with various functions has been actively conducted. Among these special fibers, especially in the heat generating fiber field, the demand is increasing every year. Types of such heating fibers include light heating fibers, metal heating fibers, and wet heating fibers.

Among them, wet heating fibers are heat generated when gasified water is adsorbed to the fibers, and have the effect of generating heat from moisture or sweat, and therefore, they are being actively studied in the clothing industry such as outdoor.

When such moist heating fibers are used in bathrobes and towels, a user can compensate for body temperature that rapidly drops after bathing and showering. However, there are several problems in using the wet heating fiber. First, the touch may not be good for the user to use, and the weight may also be heavy. In addition, since it is a functional synthetic fiber, it is not easy to process and there is a disadvantage that the cost can also increase a lot.

The present invention relates to a method of manufacturing a towel showing an unexpected high wet heating effect by using a wet heating fiber as an examination to increase the wet heating effect of the towel, and further including a plasma treatment process.

In the present invention, when weaving a bottom including a branch warp yarn and a weft yarn, a pile yarn made of a cover yarn and a wet heating fiber is bonded or bonded, or a pile yarn manufactured by covering the yarn with the cover yarn is supplied between the weft yarns to form a loop. It is possible to provide a method of manufacturing a towel including the step of manufacturing a terry fabric.

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

The term'terry fabric' used in the present invention is generally referred to as warp pile fabric, and a type of warp and weft is used to make the bottom (paper structure), and a separate pile warp is arranged again. Or it is the fabric that makes the liquor. More specifically, it refers to a multi-layered rigid pile fabric that forms a loop or curl on the face as a special warp called Terry pile.

The method of manufacturing a towel according to the present invention begins by first manufacturing a terry fabric that forms a loop by supplying a pile warp between the weft yarns when weaving a bottom including a branch warp yarn and a weft yarn.

The ground warp yarn and weft supplied to the bottom may use natural fibers commonly used in the industry, and preferably cotton fibers, hemp fibers, wool fibers, regenerated fibers, especially regenerated fibers and cellulose manufactured through melt spinning or melt spinning. Any type of fiber can be used. Most preferably, the use of cotton fibers is environmentally friendly, which is an advantage of natural fibers, and does not have any adverse effects on the skin.

The fineness of the ground warp and weft yarns is advantageous in manufacturing that the number of cotton yarns is 20 to 40, and is preferable for a good touch of the manufactured towel.

The pile warp is a combination of fibers of different materials, and may be formed of a ply-twisted yarn in which the screening and the screening are wound in a spiral manner as shown in FIG. 2 or 3, or a mixture of the screening and the cover yarns. The manufacturing method may be a conventional plying method or a covering method. However, it is preferable to combine and twist the screening yarn and the cover yarn in a volume ratio of 1:1 as it can meet the tensile strength during weaving.

The pile slopes according to the present invention can be separated and spaced apart from each other in the first dyeing step. This action is caused by contraction of the pile inclination according to the temperature of the primary dye solution composition used in the first dyeing step. This is because the tension received in the warp direction during the weaving process is removed by the temperature of the primary dye solution composition, resulting in shrinkage. to be. In addition, because the material of the cover yarn and the examination forming the pile slope are different from each other, the degree of shrinkage is different from each other, so that a separation occurs.

The screening may use wet heating fibers. By using the moist heating fiber, when moisture is absorbed into the towel, it emits high moisture absorption heat, thereby preventing a decrease in body temperature of the user.

The wet heating fiber used in the present invention is an acrylic fiber single fiber having a polar group, or a mixed yarn produced by mixing the acrylic fiber and other fibers, and the other fibers to be mixed include nylon, polyester synthetic fiber, Polyvinyl alcohol-based synthetic fibers, polyvinyl chloride-based synthetic fibers, and vinylidene chloride-based synthetic fibers may be used, but are not limited thereto.

The screening may be performed using either spun yarn or filament yarn, and if the screening is filament yarn, it is not limited to the shape of the cross section, but preferably triangular (△) or Y-shape is suitable for rapid moisture absorption and drying through capillary phenomenon. It's good because it's effective.

The fineness of the screening is preferably 60 to 160 D/72F. If the fineness of the screening is less than 60 D/72F, the cutting rate increases during the manufacture of the towel, and in the case of 160 D/72F, the fiber becomes thick and the weaving property may be significantly lowered.

The cover yarn represents the effect of the pile inclination and the towel to be manufactured, and the visual or tactile feeling of the cover yarn can be expressed to the outside as an overall effect of the composite yarn. The cover yarn is preferably made of cellulose-based fibers such as natural fibers or regenerated fibers, preferably any one selected from modal fibers, bamboo fibers, sisal fibers and regenerated fibers, or a mixed fiber thereof, most preferably It is recommended to use bamboo fiber or rayon-based recycled fiber. In particular, bamboo fiber retains the permanent refreshing sensation of bamboo itself, has excellent antibacterial and deodorant effects, improves circulation of blood circulation, and has the effect of improving metabolism (Fiber technology and industry = Fiber technology and industry / v.7 no.3, 2003, pp.359-363).

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

It is preferable that the fineness of the cover yarn is 10 to 30 surface counts. If the fineness of the cover yarn is less than 10, it becomes thicker and the weavability decreases, and if it exceeds 30, the tensile strength decreases and productivity decreases.

By using the cover yarn that touches the user's skin as a cellulose-based fiber, the user feels a good touch for use, and also maintains the user's body temperature due to the wet heat emitted by using the screening as a wet heating fiber. In addition, by using the cover yarn as a cellulose-based fiber, it may have a warming effect that maintains the heat emitted from the examination for a long time.

The pile twisted yarn may be produced through a conventional ply-twisted yarn or a covering manufacturing method. At this time, the file continuous is 6 It is preferably to 10 TPI (Twist per inch). In addition, it is preferable that the length ratio of the cover yarn to the judge is set to be judged: cover yarn = 1: 1 to 5, and more preferably, it is preferable to maintain 1: 2 to 3 to cause heat shrinkage of the pile slope in the first dyeing step. It is good to have the effect of maximizing the separation effect of the screening and the cover company to make the towel feel softer.

In one aspect of the present invention, it is possible to provide a method of manufacturing a towel in which the wet heating fiber is plasma-treated.

By further including plasma treatment on the wet heating fiber to modify the surface, higher heat can be released. Plasma treatment is performed according to a conventional method, and the treatment speed may be 0.1 m/min to 60 m/min, and the treatment voltage may be 0.1 kW to 50 kW, but it is particularly limited as long as it is sufficiently modified without damaging the wet heating fiber. It is not.

In one aspect of the present invention, it is possible to provide a method for producing a towel by plasma-treating one or both sides of the towel.

It is also possible to further increase the amount of wet heat generated by further including a plasma treatment process not only on the heating fiber but also on the entire towel. Plasma treatment is not particularly limited as long as the towel fibers are not damaged and have been sufficiently modified.

In one aspect of the present invention, after the manufacture of the terry fabric, there is provided a method of manufacturing a towel further comprising a first dyeing step of dyeing the examination of the pile warp.

Terry fabric after weaving goes through the first dyeing step of dyeing the pile warp. In the present invention, since it is preferable to use synthetic fibers such as polyester, polyolefin, polyamide, and polyacrylic, or a composite yarn thereof, the first dyeing step is preferably performed using a dispersion dye.

When using a disperse dye in the first dyeing step, since the disperse dye is usually insoluble or poorly soluble in water, a pretreatment step may be preceded to facilitate dyeing. In the pretreatment step, a pretreatment solution in which a drug containing a scouring agent, a carrier, a dispersant, and a leveling agent is mixed with dyeing water may be used.

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

The scouring agent is to remove various impurities adhering to the fiber surface, and preferably, a nonionic activator such as polyoxyalkylene alkyl ether, or a sulfate ester salt of an alkylbenzene sulfonate or an aliphatic alcohol in the nonionic activator It is preferable to mix and use anionic activators such as.

The dispersing agent is a drug that removes various impurities attached to the fiber surface, and preferably, a sodium naphthalene sulfonate-formalin condensate, sodium alkylnaphthalene sulfonate or a formalin condensate thereof, formalin of sodium phenolsulfonate and sodium naphtholsulfonate Condensate, alkyl diphenyl ether sodium disulfonate, lignin sulfonate sodium, nonionic surfactant polyoxyethylene alkyl (allyl) ether, mixing aid of nonionic surfactant and anionic surfactant, sulfonated nonionic surfactant , Sodium polyacrylate, olefin-sodium maleate copolymer, aqueous dispersant such as condensed phosphate and carboxymethylcellulose, alkylbenzene (naphthalene) sulfonate, sodium dioctyl sulfone maleate, partial amidation or partial ester of styrene-maleic anhydride copolymer It is preferable to use a non-aqueous dispersant such as cargo, fatty acid amide, polyoxyethylene alkylamine, acetate or fatty acid salt alkylamine, alkyl secondary (tertiary) amine or amide, and alkylimidazoline.

The carrier serves to increase the water solubility of the fibers by swelling to relax the fiber structure constituting the core. In addition, when using a general disperse dye, the temperature of the dye solution varies depending on the fiber, but it is usually carried out under a condition of 120°C or higher, because a cavity is formed in the fiber at or above the temperature to allow the dye to penetrate. However, in the case of using a carrier as in the present invention, there is an advantage in that the dyeing process can be effectively performed while using less energy.

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

The leveling agent (retardant) is a drug that inhibits rapid dyeing in order to prevent staining in the first dyeing step, and preferably, sodium sulfate, sodium chloride, sodium carbonate, and the like are used.

In addition, the pretreatment solution may further include an acid, which further lowers the pH of the pretreatment solution to enhance the chromaticity of the dyeing. The acid can be used commonly used in the art.

In addition, 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 Dye", Krausshungerpyeon, Wiley-VCH, Weinheim, 2003, pages 133 to 158. Therefore, you can select by referring to them. In addition, disperse dyes may be used in combination of two or more.

In addition, in order to impart other functions, in addition to disperse dyes, the primary dye composition includes antioxidants, pH adjusters, surface tension reducing agents, thickeners, moisturizing agents, thickening agents, preservatives, mold inhibitors, antistatic agents, metal ion sequestering agents and reducing inhibitors. You may use additives, such as. These additives are used together with disperse dyes during dyeing, and are imparted to the pile slope of the present invention.

It is preferable that the first dye composition contains 1 to 3% by weight of a disperse dye, 1 to 5% by weight of an additive, and the rest of water.

The first dyeing step is performed at 90 to 110°C, preferably 95 to 100°C, most preferably 96 to 98°C, which not only shrinks the screening during the pile inclination, but also the atypical part of the filament that the carrier forms the screening. By expanding the dyeing becomes more smooth, and the fastness is improved, which is preferable. In addition, it is preferable that the first dyeing step is performed for 1 to 2 hours because uniform dyeing proceeds.

In one aspect of the present invention, after the first dyeing step, it may include a method of manufacturing a towel further comprising the step of bleaching and refining the terry fabric.

After the first dyeing step is finished, the salt solution may be removed from the bath, and the scouring and bleaching step may be performed directly in the same bath. The scouring and bleaching step is a common process between the fibers forming the bottom portion and the fibers forming the pile slope, and through the above process, not only foreign substances are removed, unreacted pigments are removed, but also the effect of improving water absorption can be brought about.

The refining agent used in the refining and bleaching step may be an inorganic refining agent or an organic refining agent commonly used in the art, 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), lime (Calcium Oxide; CaO), calcium hydroxide (Ca(OH) ₂ ), etc. are recommended.

At this time, the temperature of the secondary salt solution composition was 60°C and the treatment time was 1 hour, and the secondary salt solution composition consisted of 1% by weight of a reactive dye (Lanasol CE, CIBA Specialty Chemicals) and 99% by weight of water.

After the dyeing process was completed, the secondary salt solution composition was removed in the same bath, and a soaping solution to which 1% by weight of a soaping agent (PROTEPON RSA, Protex Korea) was added was added, and the process was performed at 98° C. for 30 minutes.

After the soaping process, the soaping solution was removed in the same bath, and then a flexible solution to which 1% of a softener (CSE-920, Cheongsan Chemtech Co., Ltd.) owf was added was added, followed by 30 minutes at 40°C.

After the soaping process was finished, it was sufficiently washed with water and dried to prepare a specimen.

The hygroscopic exothermic property of the prepared wet exothermic towel was evaluated and shown in Table 1 below.

[Example 2]

The same was carried out in Example 1, except that the acrylate fiber content was included in an amount of 30 parts by weight when preparing the wet heating fiber.

[Example 3]

In Example 1, the same was carried out except that the wet heating fiber was prepared in an amount of 50 parts by weight of the acrylate fiber.

[Example 4]

In Example 1, the wet heating fiber was carried out in the same manner, except that the wet heating fiber was made only of Mg crosslinked polyacrylate without containing polyester.

[Example 5]

In Example 1, except that plasma treatment was included in the wet heating fiber, it was carried out in the same manner. The plasma treatment was performed in oxygen gas using a low-temperature plasma treatment apparatus at a treatment speed of 10 m/min and a voltage of 0.7 kW.

[Example 6]

In Example 1, except that plasma treatment was included in the towel, it was carried out in the same manner. Plasma treatment was performed in the same manner as in Example 5.

[Example 7]

In Example 5, except that plasma treatment was included in the towel, it was carried out in the same manner. Plasma treatment was performed in the same manner as in Example 5.

[Comparative Example 1]

In Example 1, the examination was carried out in the same manner, except that polyester fibers were used instead of wet heating fibers.

As shown in Table 1 above, when the heating fiber was included, a hygroscopic heating phenomenon occurred, and each time the content of the heating fiber increased, the moisture absorption and heating temperature increased. As shown in Example 5, when the plasma treatment was performed, a higher temperature increase was observed than that of Example 4 in which the plasma treatment was not performed. This proved that the heat absorption effect was better than simply increasing the content of the heating fiber when it was made of plasma-treated heating fiber. In addition, since the moisture absorption and heating temperature was the highest in Example 7, it was confirmed that plasma treatment was performed once on each of the wet heating fibers and a towel including the same, which had the best heating efficiency.
