Description

Manufacturing method of energy-saving antimicrobial towel with improved process { Method for manufacturing antimicrobial towel }

The present invention relates to an antibacterial towel, and more specifically, while performing a series of dyeing processes, it is possible to improve productivity, reduce manufacturing costs and energy by simplifying the washing and soaping processes while suppressing the occurrence of salt spots, and hygroscopicity and It relates to a method for manufacturing an antibacterial towel capable of manufacturing a more elegant and high-quality towel by improving the soft property of the surface, and an antibacterial towel manufactured by the method.

Towels are used to quickly remove moisture from the body that has come into contact with water, such as washing face, showering, swimming, etc., and are mostly made of cotton fabric. The fabric of the towel has good absorbency and a soft touch without feeling of foreign body to increase user satisfaction. However, as the number of washing increases, the feel becomes stiffer.

In some cases, post-processing such as moisture absorption processing is performed in parallel to improve these disadvantages, but moisture absorption processing has a problem in that the inherent tactile feel of the material is lowered and the durability against washing is poor, so that the softer feel is lost the more used.

Dyeing is a very important process that enhances the value of a product by giving color, design, function, and sensibility to textiles. In this dyeing process, after removing the size agent and impurities attached to the fiber during the process, various dyes and adjuvants are added, and a lot of water is used in the processing process. In addition, as a processing industry, the chemicals used and the processing process differ depending on the type of fiber that is to be processed and the processing type required by consumers, so wastewater with various characteristics is discharged according to the type of object to be dyed, processing method, type of dye, and type of processing and manufacturing. do. In dyeing wastewater, the water quality (COD, BOD, chromaticity, temperature, flow rate) of wastewater varies greatly by season, and organic synthetic chemicals are used in large amounts as dyes and auxiliary agents during dyeing processing, whereas the entire amount is not bound to the fiber that is to be processed. However, a significant amount is mixed with water and discharged, making it difficult to treat wastewater.

In addition, a large amount of heat energy is required in the reaction of the dye, the processing agent and the fiber, the fixing process, and the drying process. As mentioned above, in the dyeing and processing industry, various processes are adopted depending on the type and type of processing, and the process that discharges the most contaminants during the manufacturing process is the desizing process, the refining and bleaching process, and the dyeing process.

In the dyeing process, first, desizing and refining are performed to remove impurities adhering to the material to be dyed, including the size agent, and then, although it is omitted in some cases, it is dyed through a bleaching process that decomposes the pigment component to make it appear white, followed by a finishing process leads to Here, in the case of the dyeing process, mordant or absorbent treatment is sometimes performed as a pre-treatment process to increase the dyeing efficiency prior to dyeing. After dyeing, the fixing treatment of the dye, post-mordant dyeing, and soaping are performed depending on the nature of the dye, the state of dyeing, etc. Post-processing is also performed.

It goes without saying that dyed materials should have excellent color clarity, density, and evenness and high color fastness corresponding to the intended use, but in addition to that, products with excellent texture and appearance quality, economic feasibility, and epidemicity are also required. During the dyeing process, it is necessary to pay attention to the treatment conditions and operation so as not to damage the object to be dyed, and also pay attention to the esthetics, epidemic, economic feasibility, and suitability for use of colors and patterns.

In general, the scouring of towels to remove impurities mainly uses the alkali scouring method of treating towels at high temperature in an alkali state. The alkali refining method uses a high concentration of 98% NaOH, and after refining, it is washed several times with a strong acid such as acetic acid to adjust the pH of the fabric to be neutral, so a large amount of wastewater is generated in this process, and the temperature is lowered at a high temperature. Since a lot of energy is required to increase it, there is a problem that the processing cost is high.

In addition, during the process of removing impurities during alkali refining, the cotton fiber itself is significantly damaged, so that the texture of the fabric deteriorates and the weight is significantly reduced.

_{In Korean Patent No. 10-0780791, Na 2} CO ₃ and CH ₃ COOH are added to 800 to 1200 parts by weight of water based on 100 parts by weight of towel fabric to prepare a scouring buffer solution of pH 8.2 to 8.5, and a nonionic surfactant After mixing 1 to 3 parts by weight and immersing the towel fabric, the process of wetting and wax extraction to raise the temperature to 55 to 60 ° C by slowly heating for 10 to 20 minutes; an enzyme refining process of mixing 0.3 to 0.7 parts by weight of pectinase and 0.3 to 0.7 parts by weight of amylase, then adding 0.2 to 0.5 parts by weight of an anionic surfactant to react for 25 to 35 minutes; A method of scouring towel fabrics consisting of a soaping and water washing process in which 0.2 to 0.4 parts by weight of a soaping agent is mixed by heating to 98° C., stirred for 15 to 25 minutes, and then washed with water at room temperature three times has been proposed. However, the scouring treatment liquids so far have had the inconvenience of refining the towels by adjusting them to a specific pH condition, and thus an additional process is required to adjust the pH to neutral again, or due to this, a large amount of wastewater is generated. A number of problems still exist in the refining treatment method of .

In general, the dyeing process includes a process of pretreatment (refining, bleaching) → water washing → neutralization → water washing → dyeing → water washing → neutralization → water washing → soaping → water washing → soaping → water washing → washing → softening treatment → drying, In the dyeing stage, about 40% of undyed dye remains. If the undyed pigment and various chemical treatment agents used to extract the pigment are not sufficiently washed off, there will be problems with the fastness such as discoloration and discoloration. Since such undyed dye cannot realize dyeing quality, it is necessary to remove undyed dye.

Washing with water is a necessary process after dyeing and mordant for fabrics with excellent durability and vivid colors. Therefore, after the dyeing operation or the mordant operation, it must be thoroughly washed with water through a water washing (cleaning) process.

In particular, when dyeing blue and pink-based colors, the rate of salt spots is high, and in the conventional dyeing method, the rate of dye spots reaches 30%. In order to remove these undyed dyes, in the oval dyeing process, it is usually washed with water 7 times or more. By repeating the soaping process two or more times, energy consumption such as water and electric steam is high, and various production costs such as dyes and preparations are rising along with the increase in the overall dyeing process. There was a problem in that the productivity was lowered as this lengthened.

The method for manufacturing an energy-saving antibacterial towel with an improved process according to an embodiment of the present invention includes a bleaching process (S100) of performing bleaching on a fabric to be dyed, and a neutralization process of neutralizing the bleached fabric (S300) include

The bleaching process (S100) is a pre-treatment process of removing various impurities (organic substances, inorganic substances) contained in the towel fabric and bleaching the natural dye of the fibers. The bleaching temperature is preferably 95 to 100°C.

More narrowly, it is set at 98°C because the elution of impurities is most appropriate and the temperature is suitable for bleaching. When the bleaching time is set to 50~70 minutes, if less than 50 minutes, the elution of impurities is insufficient and the bleaching state is complete. If it exceeds 70 minutes, the effect is insignificant and energy consumption is increased.

When the neutralization process is completed, the dyeing process (S400) proceeds. In the dyeing process (S400), it is preferable to use a dyeing method and a dye for cellulosic fibers. For example, it is preferable to use any one or two or more dyes selected from direct dyes, sulfur dyes, vat dyes, azo dyes, acid dyes, basic dyes and reactive dyes. It is excellent and can be dyed in a variety of colors. Reactive dyes include yellow dyes, red dyes, and blue dyes, and the numerical values are not limited because they vary depending on the color concentration. In the case of reactive dyes, there are many undyed dyes, and since the wastewater inflow rate reaches 10 to 50% of the total dyes, it is preferable to select them in consideration of the fixation rate with fibers. The reactive dye can be applied by adjusting the temperature of the dye solution according to the strength of the reactivity, and the type is not limited as long as it is applicable regardless of the dyeing method such as batch dyeing method or continuous dyeing method.

Examples of the reactive dye used in the present invention include CIBA Specialty Chemicals 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, Cibacron LS; Blue P-NFB liquid 50, yellow P-N3R liquid 33, Red P-4B Nliquid 25 from Nippon Kayaku; Sumifix HF type from Sumitomo Chemical Industry; Dystar's Srius plus, Realan, Reanova CA; Remazol RU-N from Mitsubishi Kasei Hoechst; Zeneca's Procion CX; Clariant's Optizal dye, etc. can be used.

When the dyeing temperature is 55℃ or less, the amount of fixation of the dye decreases, and when the dyeing temperature exceeds 70℃, hydrolysis of the dye occurs and the chromaticity is deteriorated. In addition, if the dyeing time is less than 55 minutes, the dye adhesion is decreased, and if it is more than 65 minutes, energy consumption is increased without affecting the dyeing degree.

In addition, as shown in FIGS. 1 to 5 , the present invention provides an oxygenation process (S500) of oxygenating the washed dyed fabric with acetic acid (S500) A second soaping process of soaking the fabric that has undergone the oxygenation process with a second soaping agent ( S600), a hot water washing process (S700) of washing the dyed fabric that has undergone the soaping process with hot water, a softening process (S800) of softening the soaked dyed fabric, and a fixing process (S900) of fixing the softened fabric include

The soaping process is performed to prevent re-adhesion to the fibers by imparting emulsion and dispersing power to the impurities released during the refining process, and facilitates the washing process with water. If the soaping agent used in the soaping process is used in a small amount, the emulsion and dispersing power is insufficient, and if used in an excessive amount, it becomes difficult to wash with water due to the generation of bubbles. The soaping process is efficient at high temperatures, but when water boils and bubbles are generated, washing with water becomes difficult. It is carried out at a temperature of 92 ~ 98 ℃, and if the reaction is short or too long, impurities may adhere to the fibers, so it is preferable to carry out for 10 to 20 minutes, respectively.

1 to 5, in the method of manufacturing an energy-saving antibacterial towel with an improved process of the present invention, the softening process (S800) is performed at 30 ℃, 30-40 ℃ for 5 to 20 minutes. If the treatment time is less than 5 minutes, the adsorption of the softener is insufficient, and if it is more than 20 minutes, energy consumption is high compared to the adsorption effect, which is uneconomical. The fixing process (S900) is preferably performed at 60°C and 60°C to 70°C for 10 to 20 minutes.

1 to 5, in the method for producing an energy-saving antibacterial towel with improved process of the present invention, it is preferable to use 1.6 wt% of Betanol B, an imidazolium (C3H5N2) derivative, as a softening agent. When the amount of the softener used is less than 1%, the soft feel of the fiber is reduced, and when it exceeds 3%, the hygroscopicity of the fiber is reduced.
