Description

FINISHING PROCESS FOR IMPARTING WASH DURABILITY AND ANTI-BACTERIAL PROPERTIES TO TEXTILE

DETAILED DESCRIPTION OF THE INVENTION The present invention is dyeing and drying a woven fabric and then adding a resin to the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm according to the characteristics of the woven fabric. The present invention relates to a processing method for imparting laundry durability and antimicrobial properties to a woven fabric consisting of a defined product.

Microorganisms such as various bacteria and fungi exist in the living environment, and these microorganisms easily adhere to the human body or clothes through the medium and undergo a breeding process, causing skin disorders or altering the fibrin to give off odors and give off feelings.

Here, the clothing is not only breeding microorganisms due to external pollution, but also due to the sweat of the human body, a large amount of ammonia is generated not only to cause discomfort, but also cause harmful problems to the human body. Therefore, in the field of textiles, much effort has been made to develop functional fibers that can inhibit the growth of harmful bacteria.

As a typical method for imparting bactericidal properties to fibers, organosilicon quaternary ammonium salt compounds are widely used. However, laundry durability is poor and, in particular, chlorine-based detergents have a yellowing defect. In order to solve this problem, Japanese Laid-Open Patent Publication No. 54-38951 proposes to give antimicrobial properties by expressing metal ions on the surface of fibers by treating them with aqueous solutions containing copper and silver salts. have. However, since the metal ions of the copper salt and the silver salt contained in the aqueous solution react with the polymer, the physical properties thereof are lowered, so the process passability is poor in the fiber manufacturing process and the dyeing step.

As another example, in Korean Patent No. 2003-7002827, bamboo vinegar is processed into a fiber so that it does not involve yellowing, hardening or exploitation of the texture by processing. The present invention discloses antimicrobial fibers imparted with antimicrobial properties and a method for producing the same, and Korean Patent No. 1989-8511 contains dihydroxydichlorodiphenyl methane compound and / or hexachlorophene as an active ingredient in antimicrobial processing of textile materials. By providing an antimicrobial agent excellent in antibacterial effect and does not generate dioxin even when burned.

In addition, the Republic of Korea Patent No. 2005-86 provides an antibacterial pillow cover having an antibacterial function, the antimicrobial pillow cover is a colloidal nano silver 100 to 300ppm nanosilver particles of 2nm ~ 10nm size adjusted to the concentration of the existing general pillow It is manufactured by impregnating the nano silver particles into the fine yaw portion of the existing pillow cover by using a strong vortex action of the washing machine drum in the yaw portion that is a fine groove on both sides of the fabric of the cover. However, the manufacturing method is applicable to the type of yarn with a lot of wool or irregularities, such as cotton yarn, it is difficult to apply to the yarn of knitted fabrics developed as a composite and composite material. In addition, by utilizing the strong vortex action of the washing machine drum, it is difficult to give uniform washing durability and mass production is also limited.

Recently, efforts have been made to apply antimicrobial deodorization processing using nano silver having excellent antibacterial / bacterial activity and nontoxic and non-irritating properties. Nanosilver is a nanoparticle sized ultrafine particle, which acts directly on harmful bacteria such as a bias of about 10 nm, melts the cell membrane of harmful bacteria and acts on enzymes in the cell to block the inflow and discharge of nutrients and to prevent the respiratory function of harmful bacteria. It kills harmful bacteria in a short time by preventing production and destroying the growth and regeneration ability of harmful bacteria. Therefore, it is reported that almost all bacteria cannot live in contact with nanosilver for more than 5 minutes.

However, the key is to incorporate nanosilver with this excellent effect. Conventional antibacterial and deodorant processing method is to apply inorganic compounds such as silver, copper, zinc, silver oxide and zinc oxide or to apply organic compounds such as benzyl chloride. It is accompanied by a problem of non-adhesion and durability due to washing.

Thus, the present inventors have been devised to solve the conventional problems, and as a result of providing an antimicrobial processing method that can be applied to knitted fabrics including synthetic yarns and composite materials as well as cotton yarn, dyeing and drying the knitted fabrics 1 to 3 The resin is added to the antimicrobial solution containing silver nanoparticles having a particle size in the range of nm according to the characteristics of the knitted fabric, then continuously immersed and woven into mangled, dried and heat-set to impart antimicrobial activity to the knitted fabric and at the same time wash durability. The present invention was completed by confirming that it can be imparted.

It is an object of the present invention to provide a processing method for imparting laundry durability and antimicrobial properties to a woven fabric.

In order to achieve the above object, the present invention is an antimicrobial agent containing 100 to 2,000 ppm of silver nanoparticles having a particle size in the range of 1 to 3 nm attached to the silica particles of 6 to 10 nm after dyeing and drying the knitted fabric Washing durability and antimicrobial activity, consisting of continuous immersion in liquid and squeezed at a pick-up rate of 40-65% with mangle, drying at 100-150 ° C for 60-120 seconds, and heat setting at 170-95 ° C for 30-45 seconds. It provides a processing method to give.

In the antimicrobial solution of the present invention, a solution containing 100 to 2,000 ppm of silver nanoparticles having a particle size in the range of 1 to 3 nm attached to silica particles of 6 to 10 nm is diluted to 8 to 160 g / l in water. Are manufactured. In addition, the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm contained glyoxal resin 30 to 100 g / l, glyoxal resin catalyst 9 to 30 g / l, and anionic antistatic agent 5 to 20 g / l. , Amino modified silicone softener 5 to 100 g / L and fluorine-based or silicone-based water repellent 5 to 100 g / L can be prepared by further containing two or more kinds selected from the group.

Among the antimicrobial solutions containing silver nanoparticles having a particle size in the range of 1 to 3 nm, the silver nanoparticle size is 1 to 3 nm and those attached to silica particles of 10 nm or less are used.

The antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm is preferably adjusted to an acidity of pH 4-5, wherein the acidity contains silver nanoparticles having a particle size in the range of 1 to 3 nm. It is adjusted by adding 0.1 to 1.0 g / l of glacial acetic acid to the prepared antimicrobial solution.

In particular, the processing method of the present invention is preferably applied to any one of the woven fabric selected from the group consisting of polyester filament yarn, split microfiber yarn and polyester and rayon blend yarn.

Hereinafter, the present invention will be described in detail.

The present invention is dyed and dried woven fabric, and then continuously immersed in an antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm in the concentration range of 100 to 2,000 ppm, and at the same time 40-65% of pick-up rate by mangle It provides a processing method for imparting laundry durability and antimicrobial, which consists of drying with 100 to 150 ° C. for 60 to 120 seconds and heat setting at 170 to 195 ° C. for 30 to 45 seconds.

In the processing method of the present invention, the laundry durability of the woven fabric is imparted by performing a continuous immersion process on the woven fabric to the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm. In this case, the continuous immersion process is a first process of squeezing and the second process of drying and heat setting at the same time immersed continuously.

More specifically, the processing method of the present invention is the antimicrobial containing silver nanoparticles having a particle size in the range of 1 to 3 nm of 100 to 2,000 ppm concentration of the dried knitted fabric after pre-processing the knitted fabric fabric It is made by continuously immersing in a liquid and squeezing at a pick-up rate of 40 to 65% with a mangle at the same time, drying for 60 to 120 seconds at 100 to 150 ° C, and heat setting at 170 to 195 ° C for 30 to 45 seconds.

Therefore, the processing method of the present invention does not need to introduce an additional process by dyeing and drying the woven fabric and simultaneously processing the resin, which is the finishing processing of the woven fabric.

The knitted fabric may be any one selected from the group consisting of polyester filament yarn, split microfiber yarn and polyester and rayon blend yarn. Furthermore, it is natural that the processing method of the present invention can be applied to a cotton yarn which is relatively easy to handle since it can be applied to a knitted fabric including a synthetic fiber and a composite material having elasticity in one direction or in both directions.

By pretreatment processing is meant a known method which can be used for dyeing polyester filament yarns, split microfiber yarns and polyester and rayon blend yarns. Examples include processes such as gassing, desizing, boyoff, relaxation, heat treatment, refining, bleaching, mercerizing, and coloration.

Subsequently, the dried woven fabric was continuously immersed in an antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm, and woven at a pick-up rate of 40 to 65% with a mangle at 100 to 150 ° C. It is dried for 60 to 120 seconds and heat-set at 170 to 195 ° C for 30 to 45 seconds.

After the immersion, it is squeezed at a pick-up rate of 40 to 65% with a mangle. If the pick-up rate is less than 40%, the antimicrobial solution is continuously immersed to have reproducible durability antimicrobial properties, and if it exceeds 65%, The moisture content is also high and the drying time is long, which is undesirable.

At this time, the drying is preferably carried out for 60 to 120 seconds at 100 to 150 ℃, in order to maintain the color and flexibility of the knitted fabric, if carried out at a temperature of less than 100 ℃, it is continuously introduced into the subsequent process as an extension of the drying time It is difficult, and if carried out at a temperature exceeding 150 ℃, there is no effect on the antimicrobial of the knitted fabric, but the color change and the handle roughness may occur.

The heat setting is a step for sustaining the knitted fabric impregnated with the antimicrobial component containing silver nanoparticles having a particle size in the range of 1 to 3 nm performed in the above step, preferably at 170 to 195 ℃ for 30 to 45 seconds. .

In the processing method of the present invention, the antimicrobial property of the knitted fabric is imparted to the knitted fabric from an antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm.

At this time, the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm at a concentration of 100 to 2,000 ppm is prepared by diluting with stirring at 8 to 160 g / L in water.

In addition, depending on the characteristics of the knitted fabric, glyoxal resin 30 to 100 g / l, glyoxal resin catalyst 9 to 30 g / l, anion in the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm At least two selected from the group consisting of 5 to 20 g / l of an antistatic agent, 5 to 100 g / l of an amino-modified silicone softener and 5 to 100 g / l of a fluorine-based or silicon-based water repellent are further contained and prepared.

Glyoxal resin (glyoxal) performs the function of imparting fusiformity and shrinkage, it is preferable to use 30 to 100 g / l for the whole immersion liquid. If the glyoxal resin is used at less than 30 g / l, the cellulose-based fabrics are not preferable because they are wrinkled and shrinkage easily occurs after washing, and when used in excess of 100 g / l, they shrink after washing. The deformability is improved but the problem of poor commerciality as a woven fabric arises.

Glyoxal catalyst is a function that promotes the crosslinking reaction of glyoxal resin. The amount of glyoxal catalyst varies depending on glyoxal resin, and when glyoxal resin 30 g / l is used, 9 to 30 It is preferred that g / l be used. At this time, if less than 9 g / l, the crosslinking of glyoxal resin is poor and lacks fusitivity and shrinkage property, and if it exceeds 30 g / l, the handle of the fabric is worsened and the commerciality is inferior.

The amino-modified silicone softener is a function of improving the commercial property by improving the flexibility of the knitted fabric, and preferably 5 to 100 g / L is used. At this time, if the amount of use is less than 5 g / L, it is not preferable because the flexibility is insufficient, when it exceeds 100 g / L, rather the workability is poor and the surface of the fabric is slippery and the marketability is inferior.

The anion antistatic agent is used for the purpose of antistatic between fibers, and is not particularly limited, but its amount is preferably used 5 to 20 g / l depending on the composition of the material of the knitted fabric.

In addition, fluorine-based or silicone-based water-repellent agent plays a role of suppressing the penetration of water droplets to the surface of the fabric, depending on the material and use of the knitted fabric, it is preferable to use 5 to 100 g / l.

The concentration of the silver nanoparticles having a particle size in the range of 1 to 3 nm is preferably 100 to 2,000 ppm. In this case, when the concentration of the silver nanoparticles is less than 100 ppm, when the concentration of the silver nanoparticles is too low, the reproducibility and durability of the durability It is not preferable for the antimicrobial processing having, and if it is carried out in excess of 2,000ppm, in the bath of the silver nanoparticles, it is not preferable to ensure uniform dispersion and increase the production cost.

In addition, the silver nanoparticles have a particle size of 1 to 3 nm, and those attached to silica particles of 6 to 10 nm are used. In this case, since the silica particles are relatively large with respect to the silver nanoparticle size, the silica particles are combined with the silver nanoparticles so that they do not easily fall off due to physical impact and friction.

In order to ensure reproducibility of the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm, it is preferable to adjust the acidity of the antimicrobial solution to pH 4-5. The conditions impart stable dispersion and at least two selected stability in the bath to the antimicrobial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm. As a means for adjusting the acidity, it is preferable to adjust using an organic acid, and more preferably, 0.1 to 1.0 g / L of glacial acetic acid is added to an antibacterial solution containing silver nanoparticles having a particle size in the range of 1 to 3 nm. To adjust.

The amount of silver nanoparticles, glyoxal resin, glyoxal resin catalyst, antistatic agent, softener, and water repellent agent having a particle size in the range of 1 to 3 nm used may vary depending on the type of yarn, the density of the fabric, the texture, the weight, and the use. have.
