Description

Energy saving antimicrobial yarn manufacturing method {Method for manufacturing antimicrobial wool}

The present invention relates to a method for manufacturing an antibacterial yarn, and more specifically, while performing a series of dyeing processes, it is possible to achieve improved productivity and reduced manufacturing cost and energy by simplifying washing and soaping processes while suppressing the occurrence of salt spots, The present invention relates to a method for producing an antibacterial yarn capable of producing a more elegant and high-quality towel by improving the soft properties of the hygroscopicity and the touch of the surface, and to an antibacterial yarn produced by the method.

Dyeing processing is a very important process to increase the value of a product by giving color, design, function and sensitivity to yarn. In this dyeing process, after removing the sizing agent and impurities attached to the fiber in the process, various dyes and auxiliary are added, and a lot of water is used in the processing process. In addition, as a processing industry, a lot of wastewater with various characteristics is discharged according to the type of dyed material, processing method, type of dye, type of processing manufacturing, etc., as the used chemicals and processing process are different depending on the type of fiber that is the product to be processed and the type of processing required by consumers. do. Dyeing wastewater has a large variation in the quality (COD, BOD, chromaticity, temperature, flow rate) of the wastewater by season, and organic synthetic chemicals are used in a large amount as dyes and additives during dyeing processing, whereas not all of them are bound to the fiber, which is the product to be processed. It is difficult to treat wastewater because a considerable amount is mixed and discharged with water.

In addition, a lot of heat energy is required in the reaction of dyes, processing agents and fibers, fixing and drying processes. As shown above, the dyeing processing industry adopts various processes according to the type and processing type of the object to be processed. Among the manufacturing processes, the processes that discharge the most pollutants are the desizing process, refining and bleaching process, and dyeing process.

In the dyeing process, first, desizing and refining to remove impurities attached to the object to be dyed including the sizing agent, and then omitted in some cases, undergoes a bleaching process that decomposes the pigment component to make it look white, followed by finishing. Leads to Here, in the case of the dyeing process, mordant or absorbent treatment is performed as a pretreatment process to increase the dyeing efficiency prior to dyeing, and after dyeing, fixation treatment, post mordant, soaping of the dye depending on the properties of the dye and the dyeing state, etc. Some post-treatment such as etc.

It is natural that dyed products have excellent color clarity, density, and leveling properties, and must exhibit high color fastness corresponding to the application, but in addition to this, products with excellent touch and appearance quality, economy, and fashion are required. In addition to paying attention to treatment conditions and manipulations so as not to damage the dyed material during the dyeing process, it is necessary to carry out the dyeing process while paying attention to the aesthetics, fashion, economics, and suitability of the color and pattern.

In general, the refining of a towel to remove impurities is mainly using an alkali refining method in which the towel is treated at a high temperature in an alkaline state. The alkali refining method uses a high concentration of 98% NaOH.After refining, a large amount of wastewater is generated in this process, and the temperature is increased to a high temperature because the yarn is washed several times with a strong acid such as acetic acid to adjust the pH of the yarn to neutral. 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 suffers considerable damage, resulting in a deterioration in the feel of the yarn and a significant reduction in weight.

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 per 100 parts by weight of towel yarn to prepare a buffer solution for refining pH 8.2 to 8.5, and a nonionic surfactant Mixing 1 to 3 parts by weight and immersing the towel yarn, and then gradually heating for 10 to 20 minutes to increase the temperature to 55 to 60°C; An enzyme refining process in which 0.3 to 0.7 parts by weight of pectinase and 0.3 to 0.7 parts by weight of amylase are mixed and then 0.2 to 0.5 parts by weight of anionic surfactant is added to react for 25 to 35 minutes; A method for refining towel yarns comprising a soaping and washing process in which 0.2 to 0.4 parts by weight of a soaping agent is mixed by heating at 98° C. and stirred for 15 to 25 minutes, exchanged for room temperature water, and washed three times with water, has been proposed. However, until now, the refining treatment liquids have been cumbersome to refining the towel by adjusting to a specific pH condition, and for this reason, an additional process is required to adjust the pH to neutral again, or a large amount of wastewater is generated. Several problems still exist in the method of refining such as.

In general, the process of dyeing includes pretreatment (refining, bleaching) → washing → neutralization → washing → dyeing → washing → neutralization → washing → soaping → washing → soaping → washing → washing → softening treatment → drying. In the dyeing step, about 40% of undyed dye remains. If the various chemical treatment agents used to extract undyed pigments and pigments are not sufficiently washed out, problems in color fastness such as discoloration and discoloration will occur later. Since these undyed dyes cannot achieve dyeing quality, undyed dyes must be removed.

Washing with water is a necessary process after dyeing and mording for yarn with excellent durability and vivid color. Therefore, after the dyeing or mording operation, it must be thoroughly washed with water through a washing process.

In particular, when dyeing blue and pink colors, the incidence of dyeing is high, so the dyeing rate reaches 30% in the conventional dyeing method.In order to remove these undyed dyes, the ellipse dyeing process usually involves washing more than 7 times with water. By repeating the soaping process more than two 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, which is a major cause of cost increase. As this becomes longer, there is a problem that productivity decreases.

The present invention has excellent washing fastness and friction fastness while minimizing the generation of wastewater and energy consumption due to the process of refining and bleaching the towel at a conventional alkali refining solution or a specific pH, and performing several steps of washing and soaping after dyeing. The purpose is to provide an energy-saving antibacterial yarn manufacturing method that can upgrade products with effective antibacterial power and soft touch in accordance with the requirements of the importance of eco-friendly issues.

This is an improved energy-saving antibacterial yarn manufacturing method flow chart (yarn dark color). 5 is a photograph of yarn (cheese) wound around a bobbin subject to dyeing of the present invention.

As shown in FIGS. 1 to 5, a method of manufacturing an energy-saving antibacterial yarn having an improved process according to an exemplary embodiment of the present invention proceeds as follows.

(a) In the bleaching step (S100), bleaching is performed for the first time: 50 to 70 minutes at 100°C (98 to 100°C) on the yarn to be dyed (cheese state, wound on a bobbin).

(b) In the hot water washing step (S200), the yarn (the state wound around the bobbin) that has undergone the bleaching step (S100) is washed with hot water.

(c) In the neutralization process (S300), the warm water washed yarn is neutralized by using an overwater neutralizing agent (0.5 g/l) at 40° C. (38 to 45° C.) for a third time: 20 to 40 minutes.

(d) In the dyeing process (S400), the neutralized yarn at 65° C., 60 to 70° C. for 4 hours: 30 to 60 minutes is dyed while using 0.5 g/l of a dye leveling material.

(e) In the oxygen ping process (S500), the 5th hour at 65℃, 60~70℃: Oxygenation with acetic acid (CH3COOH, 1g/l) and a second soaping agent (0.5g/l) for 10-20 minutes do.

(f) In the hot water process (S600), the 6th hour at 90~95℃: Wash the hot water for 10~20 minutes.

(g) In the hot water washing process (S700), the yarn that has undergone the hot water process is washed with hot water.

(h) In the softening process (S800), the soaped dyed yarn is softened at 30° C., or 30 to 40° C. for 7 hours: 2% by weight of a softener for 10 to 20 minutes.

(i) In the fixing process (S900), the softened yarn is fixed at 60° C., 60 to 70° C. for 8 hours: 10 to 20 minutes using 0.5% by weight of a fixing agent.

As shown in Figs. 1 to 5, the method of manufacturing an energy-saving antibacterial yarn with an improved process according to an exemplary embodiment of the present invention includes a bleaching process for performing bleaching on a yarn to be dyed (a state wound on a bobbin) ( S100) and; A neutralization step (S300) of neutralizing the bleached yarn; It includes a dyeing process (S400) for dyeing the neutralized yarn.

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

The reason why the impurity is more narrowly set to 98℃ is that the elution of impurities is the most appropriate and the temperature is suitable for bleaching, and if the bleaching time is set to 50 to 70 minutes, the elution of impurities is insufficient and the bleaching state is complete. In addition, the effect of exceeding 70 minutes is insignificant and energy consumption increases.

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 cellulose-based fibers. For example, it is preferable to use any one or two or more dyes selected from direct dyes, sulfur dyes, bat dyes, azo dyes, acid dyes, basic dyes, and reactive dyes. It is possible to dye in excellent and various colors. Reactive dyes include yellow dyes, red dyes, and blue dyes, and since they vary depending on the color concentration, the numerical values are not limited. 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 it in consideration of the fixation rate with the fibers. Reactive dyes can be applied by adjusting the temperature of the dye solution according to the strength and weakness of the reactivity, and any dyes that can be applied regardless of dyeing methods such as batch dyeing method or continuous dyeing method are not limited to the type.

Examples of reactive dyes 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; Nipponkayaku's Blue P-NFB liquid 50, yellow P-N3R liquid 33, Red P-4B Nliquid 25; Sumifix HF type from Sumitomo Chemical Industry; Srius plus, Realan, Reanova CA from Dysta; Remazol RU-N from Mitsubishi Kasei Hoechst; Geneca's Procion CX; Clariant's Optizal dyes and the like can be used.

If the dyeing temperature is less than 55℃, the amount of dye adhered decreases, and if it exceeds 70℃, the dye is hydrolyzed, resulting in poor color. In addition, if the dyeing time is less than 55 minutes, dye adhesion decreases, and if the dyeing time is more than 65 minutes, energy consumption increases without affecting the degree of dyeing.

In addition, as shown in Figs. 1 to 5, the method of manufacturing an energy-saving antibacterial yarn with an improved process according to an embodiment of the present invention includes a soaping process (S500) for soaping the washed dyed yarn, and a soaping process ( Hot water process (S600) for washing the yarn passed through S500) with hot water; It includes a hot water washing process (S700) of washing the dyed yarn with hot water.

The soaping process is performed to prevent re-adhesion to the fibers by imparting emulsification and dispersing power to the impurities released during the refining process, and facilitates the water washing process. If the soaping agent used in this soaping process is used less, the emulsification and dispersing power is insufficient, and if it is used too much, washing with water becomes difficult 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 60 to 70°C, and if it is reacted shortly or for too long, impurities may adhere to the fibers, so it is preferable to perform each of 5 to 15 minutes.

In addition, as shown in Figs. 1 to 5, the method of manufacturing an energy-saving antibacterial yarn having an improved process according to an embodiment of the present invention includes a softening process (S800) for softening the soaped dyed yarn, and the softened yarn It includes a fixing process (S900) of fixing.

The softening process (S800) is performed at 30°C and 30°C to 40°C for 5 to 20 minutes. If the treatment time is less than 5 minutes, adsorption of the softener is insufficient, and if the treatment time is more than 20 minutes, it is uneconomical because it consumes more energy compared to the adsorption efficiency. The fixing process (S900) is preferably performed for 10 to 20 minutes at 60° C., 60 to 70° C.

As shown in FIGS. 1 to 5, in the method of manufacturing an energy-saving antibacterial yarn with an improved process according to an exemplary embodiment of the present invention, in the neutralization process (S300), a catalase, which is a microbial hydrogen peroxide decomposing enzyme, 0.5 It is preferred to use g/l.

As shown in FIGS. 1 to 5, in the method for manufacturing an energy-saving antibacterial yarn with improved process according to an embodiment of the present invention, the softening process (S700) is performed at 30° C. for 5 to 20 minutes, and the The fixing process (S800) is preferably performed at 60° C. for 10 to 20 minutes.

Further, it is preferable to use 2% by weight of Betanol B, an imidazolium (C3H5N2) derivative, as a softening agent. If the amount of the softener is less than 1%, the soft texture of the fibers is lowered, and if it exceeds 3%, the moisture absorption of the fibers is lowered. Belfasin GT can be used as a cheese softener.

6 is a result of a washing fastness test result of the cheese yarn manufactured according to the first embodiment of the present invention. In the case of domestic standards, washing fastness is set to 3 or more. In the case of this product, it was found that the washing fastness was 4~5, indicating that the washing fastness was improved compared to the conventional product in washing fastness, indicating excellent quality.
