Description

Fragrance fabric produced by using the fragrance coating composition and its manufacturing method {FRAGRANT TEXTILE PRODUCED BY USING FRAGRANT COATING COMPOSITION AND A PROCESS OF PRODUCING SAME}

The present invention relates to a fragrant fabric prepared by coating with a coating composition containing a fragrance component coated with microcapsules, and a method for manufacturing the same, wherein the microcapsules coating the fragrance component are firmly adhered to the fabric and are repeated. The present invention relates to a fragrant fabric and a method for producing the same, wherein the fragrance is maintained for a long time even after washing and rubbing.

Research into the inclusion of fragrance ingredients in fabrics to give off their fragrance as they evaporate has long been ongoing. Therefore, a method of applying the fragrance component itself to the fabric has been attempted, but in this case, the fragrance component is rapidly consumed by continuously evaporating or subliming the fragrance component, and the fragrant fabric thus prepared is washed with water and detergent. As a result, the fragrance component applied to the fabric was almost removed and thus fragrance could not be maintained for a long time.

In order to overcome this problem, a method of applying a microcapsule containing a fragrance component to the fabric has been proposed. That is, by preparing a microcapsule containing a fragrance, and applying the microcapsules thus prepared to the fabric, the fragrance is maintained in the capsule without vaporization, the fragrance is released while the microcapsules burst little by little by friction Attempts have been made to allow the components to be retained for a long time.

As a fiber composite processing method using the fragrance microcapsules as described above, a method of producing a fragrant cotton fabric by immersing the fabric in an aromatic microcapsules and a cationic binder at room temperature for 10 minutes, followed by washing with water and drying (Hong Gijung et al., Development of Emotional Functional Fiber (I), Vol. 8, No. 5, Nov. 1996). In addition, Kim Moon-sik and others announced a method of immersing the fabric for 10 minutes at room temperature in a microcapsule (5% owf) and binder (5%, owf) bath ratio 20: 1, and then treated for 20 minutes at 70 ℃ (Kim, et al., Development of Emotional Functional Fiber by Microencapsulation of Emotional Substances (III), Journal of the Korean Society of Dyers and Finishers, Vol. 8, No. 4 (1996. 11.). In addition, a method of treating microcapsules having antimicrobial aroma characteristics with respect to polyester fabrics using an acrylic binder for fibers has been disclosed. (A study on antimicrobial and aromatic fibers using microcapsules of antimicrobial agents and fragrances, such as Kim Ho-Jung, etc. , Journal of the Korean Society of Clothing and Textiles, Vol. 20, No. 5 (1996)).

However, the fiber composite processing method using the fragrance microcapsules using the general padding method as described above, there is a problem that the fragrance microcapsules are hardly bonded to the fabric by the weak bonding force. That is, the method of immersing the fabric in a bath mixed with a soft binder for post-treatment of aromatic microcapsules and then drying the capsule was not firmly combined with the fabric. It became. According to this trend, it is difficult to expect that the aromatic microcapsules decrease rapidly after about three to four washings are repeated, so that the fragrance is substantially maintained in the fabric.

The present invention provides a new fragrance fabric with a fragrance microcapsule and a method for producing the same, which are manufactured to have a greater durability against repeated washing and rubbing and to maintain and release the fragrance component for a long time. do.

In particular, the present invention provides a whole or partial coating of the fragrance microcapsules onto the fabric using a glue type resin composition having a much stronger binding force than a general post-treatment soft binder, thereby requiring more washing durability than the texture of the fabric. It is an object of the present invention to provide a fragrant fabric having aroma, deodorant and deodorant effect on the bottom part of a sock or shoe sole, and a manufacturing method thereof.

Furthermore, the fragrant fabric according to the present invention, by printing the fabric in a predetermined pattern using a resin composition having a stronger bonding force as described above, due to the thickness of the printed portion can also expect the effect of acupressure and anti-slip It is an object of the present invention to provide a new fragrant fabric and a method for producing the same.

The object of the present invention,

(a) about 5% to 49% by weight of the flavor microcapsules and about 51% to 95% by weight of the sol type adhesive resin are mixed to prepare a coating composition,

(b) coating the fabric in whole or in part with the coating composition,

(c) can be achieved by a method for producing a fragrant fabric comprising a step of curing the composition coated on the fabric.

When the above configuration is described in detail, the present invention preferably provides about 5% to 49% by weight of fragrance microcapsules, more preferably about 10% to 35% by weight, which may be present in emulsion or powder form, and emulsion type adhesives. Resin, preferably from about 51% to 95% by weight, more preferably from about 65% by weight, to an adhesive resin selected from the group consisting of aqueous or oily acrylic acid ester resins, silicone resins, rubber, pvc, and polyurethane resins. By mixing 90% by weight, a coating composition containing the fragrance component to be applied to the fabric is prepared.

The emulsion-type resin acts as an adhesive for attaching the fragrance microcapsules to the fabric, and if it is an aqueous resin, the composition may be prepared by including a certain amount of solid resin and then replenishing the remainder with water.

When the fragrance microcapsules are used at less than 5% by weight, the fragrance that can be felt when the fabric is coated is very insignificant, and it is difficult to maintain the durability. It is not preferable to use at least 49% by weight in terms of efficiency and economy. . Therefore, in order to exhibit sufficient aroma and durability, it is preferable to use at least 5% by weight or more of perfume microcapsules, and more preferably to use 10% by weight or more.

Furthermore, the coating composition may further comprise auxiliary additives such as colorant aids, thermochromic microcapsules, jade, chitosan, etc., which have no effect on the orientation of the composition, depending on the purpose or use of the print composition. It imparts additional properties to, and may be included and used in an appropriate amount depending on the type and use of each additive.

The colorant adjuvant may be included and used when the coating composition is to have the same or similar color in consideration of the color of the fabric to be coated, or to have a color distinct from the color of the fabric.

Depending on the purpose, the coating composition may also further comprise thermochromic microcapsules. The fabric coated with the coating composition including the thermochromic microcapsules may not only smell, but also change the color of the coated portion before and after a desired temperature.

In addition, for the purpose of health promotion, the coating composition may further comprise a component such as jade or chitosan.

Next, according to the method of the present invention, a process of coating the fabric to be produced as a fragrant fabric with a coating composition prepared as described above. The coating is done in the same way as the coating of the fabric with ordinary pigments. That is, the coating composition is placed on the upper surface of the printing plate to be printed, and the lower surface is placed on the fabric to be printed, and the top plate is lowered to scrape and print the desired coating composition so that the composition is coated on the fabric. As noted above, the coating may be throughout the fabric or only partially coated.

When the coating is finished, the step of cross-linking between the resin and the fabric of the microcapsules by curing the coating composition printed on the fabric. Microcapsules bind more tightly to the fabric by crosslinking with the fabric. Curing for crosslinking may have a slightly different curing temperature and time depending on whether the adhesive resin (emulsion resin) used to prepare the coating composition is aqueous or oily, but generally a temperature of about 150 ° C to 210 ° C. By drying for about 3 to 10 minutes. Preferably, when the adhesive resin is oily, it is preferable to dry for 3 minutes to 5 minutes at a temperature of about 180 ° C to 200 ° C, and when the adhesive resin is aqueous, 5 minutes to 10 minutes at a temperature of about 160 ° C to 190 ° C. It is good to dry to a degree.

More preferably, the curing process is to place the printed fabric as described above on the rotating circular plate while rotating, the first heat treatment for about 50 seconds to the printed fabric at a temperature of about 150 ℃ at one end of the circular plate After the first heat-treated product at a speed of 6m / 3 minutes in the same place as the tender, by the second heat treatment at a temperature of about 160 ℃ when using an aqueous resin, about 180 ℃ when using an oil resin It is composed.

The fragrant fabric produced in this way is more strongly attached to the fabric by the resin composition of a much stronger bonding composition than the fabric attached with the fragrance microcapsules prepared according to the conventional method, thereby preventing washing or friction. It is highly durable, thus keeping fragrance components for longer periods of time.

Fabrics to which the coating composition can be applied in accordance with the method of the present invention can be applied to any kind of fabric, such as cotton, acrylic, nylon, polyester, spandex. The fabric thus prepared may be used to produce socks, stockings, soles, etc., which require particularly strong wash durability but are less affected by the texture of the fabric.
