Fragrance Yarns and their manufacturing method

The present invention relates to a fragrance yarn and a method for producing the same, and more particularly, to prepare a pellet or powdery fragrance master batch mixed with a variety of finely powdered fragrance components with a synthetic resin, and mixing the fragrance master batch with a synthetic resin The present invention relates to a fragrance yarn and a method for producing the same, which are excellent in stability as a fragrant yarn (fragrance yarn) by forming yarns through melt spinning and the like, and have a long-lasting fragrance divergence and a reduction in work processes.

In general, a method for producing fragrance fibers is a liquid coating composition containing a fragrant substance such as plant flavor, fruit flavor, coffee flavor, chocolate flavor on the woven fiber surface or microcapsulation of the flavor (Capsulation) It was common to produce functional fibers by coating the fiber surface or yarns.

However, these functional fibers have a problem that the functional material is difficult to fully adhere to or absorb the fibers or yarns, so durability is reduced, and the original functionality does not continue as the number of washing increases.

Accordingly, the present invention has been made to produce a functional fiber that permanently scents to solve the above disadvantages, the nano-sized ultra-fine powder, or a powder containing a fine powdered fragrance component and synthetic resin Mixing the fragrance master batch of pellets or powder form, and mixing the fragrance master batch with a synthetic resin to prepare a basic yarn through a process such as melt spinning and stretching it to produce a fragrant yarn, the physical properties of the synthetic yarn itself It is an object of the present invention to provide a fragrance yarn and a method for producing the same, which are excellent in stability as a fragrant fiber and are sufficiently dispersed, there is no deterioration in the physical properties of the fiber, and the fragrance divergence is long lasting.

The present invention for achieving the above object relates to a fragrance yarn containing a fragrance powder prepared by mixing, melt spinning the fragrance powder and a thermoplastic synthetic resin and a method for producing the same. More specifically, the present invention relates to a method for producing a fragrance yarn consisting of 0.45 to 12% by weight of the fragrance powder and a synthetic resin.

The present invention also relates to a fragrance yarn and a method for producing the fragrance powder master batch, which is then mixed with a thermoplastic resin to melt and prepare under spinning.

In the preparation of the masterbatch, more specifically, a mixture of 70 to 97% by weight of thermoplastic resin and 3 to 30% by weight of fragrance powder or 69 to 91.7% by weight of synthetic resin, 3 to 20% by weight of fragrance powder, and 5 to 10 weight of polymer dispersant %, And a mixture of at least one component selected from 0.3 to 1% by weight of the antioxidant is melt-extruded at a temperature of 120 ℃ ~ 380 ℃, then cooled to a temperature of 4 ℃ ~ 95 ℃ to produce a pellet or pellets at a low temperature Preparing a fragrance masterbatch to be pulverized by a method such as pulverization to prepare a powder;

15 to 40% by weight of the fragrance master batch and 60 to 85% by weight of thermoplastic synthetic resin are mixed in a stirrer to stir the mixture;

A basic yarn manufacturing step of manufacturing a yarn in an initial state by melt spinning the mixture at a temperature of 120 ° C. to 380 ° C .;

A cooling step of cooling the basic yarn formed in the basic yarn manufacturing step at a temperature of 4 ° C. to 95 ° C .;

And, the stretching step of forming the fragrant yarn (fragrance yarn) by stretching the basic yarn after the cooling step at a temperature of 20 ℃ ~ 280 ℃;

Method for producing a fragrance yarn comprising a, including the technical gist.

Further, the present invention provides a fragrance yarn in which the fragrance yarn 0.45-12% by weight of the fragrance powder is evenly dispersed in the interior of the fiber, when the fragrance powder is 0.45 wt% or less, the fragrance performance is very weak or not expressed, In the case of more than 12% by weight, the physical properties of the fragrance yarns are inferior, and mechanical properties are not good, such as cutting occurs during processing.

Here, the fragrance master batch forming step or mixing step may further include a pigment, the synthetic resin is not limited as long as ordinary thermoplastic resin, for example, polyester, polypropylene, polyethylene, polyamide, polyurethane, polyolefin , Poly (meth) acrylic resin, modacryl, vinylon, nylon, polyvinylacetate, triacetate, vinyl chloride resin, viscose, ABS, etc. may be one of synthetic resins (Synthetic Resin), but is not limited thereto. The particle size of the scented powder may be 10 microns or less, preferably nano sized micro fine size or 3 μm or less fine size particles to minimize the cutting during spinning and also maintain the strength.

After the fragrance yarn of the present invention, the fragrance master batch containing a synthetic resin is prepared, the prepared fragrance master batch is mixed with a synthetic resin to form a mixture, and the mixture is melt-spun to prepare a basic yarn, followed by cooling and stretching. Manufacture.

Accordingly, the fragrance master batch prepared by mixing the fragrance (fragrance) powder and the synthetic resin first is sufficiently dispersed in the fragrance powder, and then the fragrance master batch is mixed with the synthetic resin to prepare the fiber through a process such as melt spinning and the like. It has excellent stability and fragrance power, has the advantage of long lasting fragrance dissipation power, and distributes the fragrance powder uniformly in the secondary fiber, which is distributed evenly inside the fiber to prevent the cutting of fiber and the deterioration of mechanical strength. .

Hereinafter, the present invention will be described in detail.

Firstly, aroma master batch thermoplastics, for example polyester, polypropylene, polyethylene, polyamide, polyurethane, polyolefin, poly (meth) acrylic, modacryl, vinylon, nylon, polyvinylacetate, triacetate, vinyl chloride, viscose To the synthetic resin composed of one, such as ABS, the fragrance powder and the polymer-based dispersant and / or antioxidants are added by necessity and prepared by melt stirring in a stirrer. In addition to the above components, a pigment may be further added as necessary.

That is, the particle size of the thermoplastic resin is 70 ~ 97% by weight of the particle size of 10㎛ or less particles, more preferably nano-size or 3 to 30% by weight of the scented powder ground to 3㎛ or less In addition to the mixture or the synthetic resin and the fragrance powder, a mixture of at least one component selected from 5 to 10% by weight of a polymeric dispersant and 0.3 to 1.0% by weight of an antioxidant is mixed with a stirrer to form a mixture, and then the temperature in the stirrer. Stir in a state of about 15 ℃ to 30 ℃. In the stirring method, when high-speed stirring in the stirrer, the synthetic resin generates frictional heat due to mutual friction, and the viscosity is generated on the surface of the synthetic resin. Thus, the fragrance substance and the polymer-based dispersant in the powder form adhere to the surface of the synthetic resin evenly mixed. After the synthetic resin surface is coated with a powdery fragrance powder and a polymeric dispersant, the mixture is transferred to an extruder and melt-extruded at a temperature of about 120 ° C. to 380 ° C., and then cooled to 4 ° C. to 95 ° C. in a cooler. After drying in the dryer, it is cut into cutters to form pellets or powders. The powder form can be produced by a method such as low temperature grinding the pellets.

The fragrance powder used in the present invention is a fruit powder obtained by drying fruits such as lemons, apples, bananas, oranges, cherries, pomegranates, mangoes, strawberries and grapes, and finely powdered fruits, acacias, roses, lilies, lilacs, frangipani and chestnut flowers. Plant powder finely dried by drying various parts of the plant, such as peppermint, jasmine, rosemary, lavender, wormwood, brush, flavono and fir scent can be used.

Solid flavors such as menthol, camphor, eucapitol, and anetol, and synthetic flavors such as maltol and vanillin in solid form may be used. Sometimes. Another form of solid powder used in the present invention is a method of adsorbing a liquid fragrance to a solid component, for example, a method of adsorbing to a porous inorganic material such as zeolite, silica, but is simply adsorbed It is not suitable because the liquid fragrance volatilizes during melt kneading or extrusion processing, thereby imparting a sufficient aroma effect, but may be used if necessary within the range of not lowering the mechanical properties of the fiber. In addition, the fragrance powder of the present invention may be used in the kneading and extrusion processing, melting in a solid state in a liquid state, in the case of a liquid flavoring material in the liquid state at room temperature in general, but can not be used because it is rapidly volatilized in the melting and extrusion step In the case of a solid perfume at room temperature but a non-volatile liquid in molten and extruded state, it may be used since it is solidified and evenly distributed inside the manufactured fiber.

In the present invention, the fragrance powder may be mixed with the resin as it is, but in the case of producing a fragrance yarn by spinning with the resin, the dispersibility of the powder is poor, and sometimes problems such as cutting during spinning of the basic yarn may occur. Therefore, it may be best to solve the above problems when spinning by producing a fragrance master batch using the fragrance powder and then mixing it with the thermoplastic resin component again. In addition, it is important to use additives such as natural fragrance yarn during the dispersion, and to prevent deterioration during processing by adding an antioxidant and a polymer-based dispersant together.

In the present invention, when the fragrance powder and the resin is melted to prepare a master batch or as it is mixed and spun as the fragrance powder and the resin to produce a basic yarn, the fragrance powder having thermal stability is inferior in the kneading or spinning process. In order to prevent carbonization due to the increase, the number average molecular weight is preferably added to the synthetic oil, such as silicone oil, mineral oil, polyolefin wax 10 million to 20 million, and the content is preferably used 0.01 to 2% by weight based on the total composition. . If less than 0.01% by weight can not give a sufficient lubricating effect may not have the effect of preventing local carbonization, if more than 2% by weight is not good because the mechanical properties of the yarn is bad.

The polymeric dispersant used in the present invention is not limited as long as it satisfies the mechanical properties of the fragrance yarn prepared without dispersing the interface by dispersing the perfume powder and the pigment component added as needed evenly on the matrix resin. And nonionic and anionic surfactants of polyoxyethylene alkylaryl ether condensates or naphthalene sulfonate acid formalate condensates. In this case, the amount of the dispersant is preferably 5 to 10% by weight, but when the dispersant is 5% by weight or less, the dispersibility of the fragrance powder is not good, and in the case of 10% by weight or more, the mechanical properties of the final fiber are not good. It is good to use as a range.

In the next mixing step, the mixing step of mixing and stirring the fragrance master batch and the thermoplastic resin used to prepare the masterbatch proceeds, and preferably using the same resin component as the resin component used to prepare the fragrance master batch. Good for uniform kneading

In the kneading step, the mixing ratio of each material is mixed to about 60 to 85% by weight of the synthetic resin with respect to 15 to 40% by weight of the fragrance master batch, and the mixing step is completed by mixing in an agitator. In the present invention, a pigment may be added as necessary in the mixing step. As commonly used in the art, which is introduced in the fragrance masterbatch or kneading step of the present invention, unless otherwise stated, the size of the pigment is 10 microns or less, preferably using a pigment having a particle size of 3 microns or less It is good without disturbing the physical properties of the fragrance yarn.

Next, the manufacturing steps of the basic yarn will be described. Basic yarn is first prepared by melt spinning and cooling the mixture mixed in the mixing step at a temperature of about 120 ℃ ~ 380 ℃.

The cooling step prevents the basic yarns from adhering to each other by cooling the basic yarns radiated by the radiator at a temperature of 55 ° C to 95 ° C.

The cooled basic yarn is drawn to a length of 2 to 50 times at a temperature of 20 ℃ ~ 280 ℃ and the fragrance yarn prepared by the process of producing a final yarn fragrance yarn is to be wound in a winder.

The fragrance yarn formed in the stretching step is woven or knitted using a loom, knitting machine, etc., sock, stockings, pantyhose, underwear, bra, blouse, shirt, tie, handkerchief, scarf, gloves, interior, rug, car seat cover , Etc. and other products and the final fiber.

The fragrance yarn according to the above constitution is excellent in stability as a fragrant substance by adding a powder of fragrant substance (fragrance) from the step of forming the yarn to form a yarn, and the fragrance divergence power lasts for a long time.

Hereinafter, the present invention will be described in detail with reference to examples, and the present invention is not limited to the following examples.

Example 1

Extreme viscosity measured with 13% by weight fine apple powder with a regular particle diameter of 1.2 μm, 8% by weight of polyethylene glycol dispersant with a number average molecular weight 2500 and 0.5% by weight of Iganox 1035 as an antioxidant and 0-chlorophenol solution at 25 ° C. After mixing 78.5% by weight of polyethylene terephthalate resin of 0.64, melt kneading at 272 ° C. using a twin screw extruder, followed by extrusion and pelletizing to prepare fragrance master batch pellets.

13 wt% of the fragrance masterbatch prepared above and 87 wt% of the same polyester resin used in the masterbatch were melt-kneaded at 290 ° C by extruder, followed by 24 spinnerets having an aperture of 26.7 g / min. Was discharged. Blow the cooling wind of 20m / min and 20 ℃ on the discharged basic yarn to cool below the glass transition point, and introduce the strand into the 1.3m long heating tube installed below 1.6m of the spinneret. Taken as speed, a thread of 50 denier 24 filaments was obtained. As the heat treatment apparatus between the rollers, steam was introduced into the apparatus using a 300 mm steam treatment apparatus and wound up at 98 ° C. to produce 49 d / 36 f of fragrance yarn.

In order to evaluate the fragrance persistence of the fragrance yarn after washing up to 50 times, the fragrance was selected by 10 evaluators and the sensory test for the fragrance did not show a significant difference in the fragrance of the composition of the present invention is very excellent It was found to have a lasting effect of antibacterial and antifungal.

Comparative Example 1)

According to the method disclosed in Korean Patent Laid-Open Publication No. 1991-0004891, the self-emulsifying water-soluble polyurethane resin and the forced-emulsifiable water-soluble polyurethane resin are 1: 1 in 85% by weight of water. 10% by weight of the mixture was added at a weight ratio of 1%, and the internal composition of the fragrance-containing microcapsules (jina fragrance MELON 201TEENS) to 5% by weight to complete the basic composition, the fiber made of the same polyester as in Example 1 After immersing and passing the padder at a pressure of 5 Kg / cm ² or less to make the weight increase to 60-100% compared to the dry, and then dried by hot air at 60-100 ℃ for 1-5 minutes to the weight of the solids to the weight of the fiber This 3.0% and after fixing it again for 3 minutes with a hot air of 170 ℃, the same functional experiments as in Example 1 showed that the fragrance did not occur in 10 washes.

Example 2

Except that 13 wt% of the fragrance master batch, 86.7 wt% of the polyester resin of Example 1 and 0.3 wt% of silicone oil having a number average molecular weight of 1700 were used in the preparation of the basic yarn in Example 1. The results showed that the kneading and discharging pressure of the desiccant during the manufacturing process of the fragrance yarn was lowered, and the fragrance functional test performed in the same manner as in Example 1 did not show any difference so that the fragrance persistence was very excellent. there was.

The present invention by the above configuration, by adding the fragrance powder from the basic step of forming the yarn to form a yarn, while maintaining the physical properties of the fiber itself, the fragrance component, that is, the fragrance can be long lasting and durable even when washing This is effective. In addition, since the fragrance powder component is contained in the yarn itself in the form of particles, there is no need to undergo a separate fragrance divergence treatment process, thereby reducing the number of processes according to the production of the product.
