Description

Cosmetic nylon fiber and manufacturing method thereof

The present invention relates to a cosmetic nylon fiber comprising an organic microcapsule containing an active skin cosmetic ingredient and a method for manufacturing the same.

Cosmetic fibers (cosmetics functional fibers) have been officially defined by the European Committee for Standardization (CEN). Cosmetic fibers are textile products containing substances that can continuously release the active ingredients of cosmetic functions to the human body, especially the skin. It provides reliable cosmetic effects such as elasticity enhancement and wrinkle improvement.

These cosmetic fibers support the active ingredients of cosmetics and mix them when manufacturing yarns to control the release of the active ingredients gradually so that the active ingredients are continuously delivered and penetrated into the skin, or the capsules are placed on the fiber surface by using a binder as a post-processing technology. When the capsule is broken by friction, the active ingredient is released and delivered and penetrated into the skin.

In the case of the post-processing method, the initial release effect is excellent, but the durability of the effect is low, and in particular, the performance durability is limited. has possible strengths.

However, the technical difficulty of the yarn mixing method is very high, so only a few leading companies in the world currently have manufacturing technology. It is in a state of preoccupation with the market, and is currently under development for performance upgrade.

On the other hand, in the case of functional natural cosmetic materials, in particular, there are many known substances for cellulite decomposition and moisturizing/skin elasticity enhancing substances, and these substances are used as cosmetic fiber effective substances.

In addition to the existing substances with known efficacy, it is necessary to discover more effective natural products/compounds in terms of efficacy and skin permeability.

In addition, most of the natural and synthetic materials that can be absorbed percutaneously are low molecular weight materials, which are easily exposed to oxidation and reduction reactions, and have poor thermal stability. There is a problem that cannot be applied.

In addition, most garments should be able to guarantee long-term performance of one year or more, and should have stability that does not cause denaturation or loss in fiber processing conditions along with long-term maintenance and uniform efficacy expression.

Accordingly, the above conditions can be satisfied by isolating or polymerizing the cosmetic functional active ingredient from the external environment. In order to isolate it from the external environment, it is necessary to introduce a heat-resistant capsule type or a porous inorganic carrier. However, since the inorganic carrier has nanopores, it has a problem in that it is not effective for supporting large substances at the molecular level.

In order to solve the problems of the prior art as described above, the present invention supports and controls the active ingredients to be gradually released by supporting the active ingredients for skin care and mixing them when manufacturing the yarn, thereby continuously delivering and penetrating the active ingredients into the skin. An object of the present invention is to provide a cosmetic nylon fiber that can be used and a method for manufacturing the same.

In addition, the cosmetic nylon fiber may have a single yarn fineness of 1 to 3 denier, a strength of 3.5 g/d or more, and an elongation of 35% or more.

In addition, the method of manufacturing a cosmetic nylon fiber according to an embodiment of the present invention comprises: organic microcapsules or porous ceramic particles carrying active ingredients for skin care; and melt-mixing nylon to prepare masterbatch chips; and melt-mixing the masterbatch chip and the nylon chip and spinning.

Here, the masterbatch chip may include 10 to 30% by weight of the organic microcapsules or porous ceramic particles.

In addition, the organic microcapsules may be prepared by adding a surfactant and a skin cosmetic active ingredient to a solvent to prepare a first solution; preparing a second solution by mixing one selected from the group consisting of melamine-urea, polyurethane, silicone, polyurethane-silicone hybrid, polystyrene and nylon in a solvent; and mixing the first solution and the second solution to prepare an organic microcapsule.

In addition, the surfactant may be at least one selected from the group consisting of sodium dodecyl sulfate, sodium dodecylbenzenesulfonate and stearyl methacrylate.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Cosmetic nylon fiber according to an embodiment is characterized in that it comprises an organic microcapsule carrying an active ingredient for skin care.

In addition, the cosmetic nylon fiber may further include porous ceramic particles supporting skin cosmetic active ingredients. In this case, there is an advantage that different cosmetic materials can be applied to the organic microcapsule and the porous ceramic particles in a complex manner, and the functionality of releasing the active ingredient while maintaining the basic fiber properties can be expressed.

Specifically, the cosmetic nylon fiber according to the present invention supports the active ingredient for skin care in an organic microcapsule and mixes it when manufacturing a yarn to control the active ingredient to be gradually released, so that the active ingredient can be continuously delivered and penetrated into the skin. have.

At this time, as the cross-section of the yarn of the cosmetic nylon fiber, various cross-sections such as round, flat, and still yarn may be applied, but it is preferable to improve the contact area of the skin by using a release method. More specifically, the degree of irregularity is preferably 3 or more similarly to flat yarn. In addition, the area in contact with the skin may be wide and contain a large amount of skin cosmetic active ingredients, and in order to increase the refreshing feeling, a W cross-section having high bulky properties may be applied to the cross-section of the yarn.

In addition, the cosmetic nylon fiber preferably has a single yarn fineness (dpf) of 1 to 3 denier, and as such, there is an advantage that a functional material (skin cosmetic active ingredient) can be stably added according to the decrease in the single yarn fineness.

Cosmetic nylon fibers have a strength of 3.5 g/d or more, and an elongation of 35% or more, which can express the functionality of releasing active ingredients while maintaining basic fiber properties.

On the other hand, the organic microcapsule carrying the skin cosmetic active ingredient may be included in 0.5 to 5% by weight in the yarn. If the content of the organic microcapsule is less than 0.5% by weight in the yarn, it may cause deterioration of skin beauty performance, and if it exceeds 5% by weight, spinning workability and deterioration of yarn properties may occur.

In addition, the organic microcapsules may have an average particle diameter of 0.1 to 1.5 μm, preferably 0.5 to 1.0 μm. When the average particle diameter of the organic microcapsules is less than 0.1 μm, functional deterioration may occur, and when the average particle diameter exceeds 1.5 μm, a problem in fine spinning workability with single yarn fineness of 1 to 3 denier may occur. The average particle diameter of organic microcapsules is easy to control by optimally controlling the type and concentration of surfactant, emulsification conditions, emulsion polymerization and crosslinking reaction conditions during capsule manufacturing.

On the other hand, the organic microcapsules include a core containing active ingredients for skin care; And melamine-urea, polyurethane, silicone, polyurethane-silicone hybrid, polystyrene and may include a shell including one selected from the group consisting of nylon. At this time, in the present invention, using a shell containing melamine-urea will be described as an example.

These organic microcapsules are prepared by adding a surfactant and a skin cosmetic active ingredient to a solvent to prepare a first solution; preparing a second solution by mixing melamine and urea in a weight ratio of 7:3 to 9:1; and mixing the first solution and the second solution to prepare an organic microcapsule.

More specifically, the step of preparing the first solution may be a step of preparing a first solution by adding a skin cosmetic active ingredient to an emulsifier in which a surfactant is mixed with a solvent and homogenizing it. At this time, the particle size of the capsule to be manufactured is changed according to the type of surfactant. Accordingly, the surfactant is preferably at least one selected from the group consisting of sodium dodecyl sulfate (SDS), sodium dodecylbenzenesulfonate (SDBS) and stearyl methacrylate (SMA).

On the other hand, the content of the surfactant based on the total weight of the emulsifier may be 2 to 10% by weight, preferably 5 to 10% by weight. In addition, it is preferable that the stirring speed of the emulsifier is 5000 to 10,000 rpm, and the stirring time is 5 to 10 minutes. Here, in order to control the average particle diameter of the capsule, the concentration of the emulsifier and the stirring time were fixed, and the capsule was prepared by varying the stirring speed. As a result, it can be seen that the particle size of the capsule decreases as the stirring speed increases. Therefore, in the present invention, by adjusting the stirring speed, the particle size of the capsule can be adjusted.

In addition, skin beauty active ingredients include cypress oil, green tea seed oil, lecithin, caffeine, green tea, moisture CPX, skin firming, anti cell, water-soluble ceramide, capsaicin, evening primrose oil, geranium. It may be at least one selected from the group consisting of oil, grapefruit oil, vitamin E, camellia oil, jojoba oil, horse oil, grape seed oil and safflower seed oil. It is preferable that such an active ingredient for skin care is 15 to 25% by weight based on the total weight of the first solution.

On the other hand, the step of preparing the second solution, which is a polymer precursor, may be a step of preparing a second solution by mixing melamine and urea and then stirring.

Melamine resin has excellent heat resistance, but has a hard property and has a problem of being easily broken by strong pressure. It is characterized by making it into a flexible form that can better withstand pressure by creating a defect.

Capsules used for spinning must first be secured with heat resistance to withstand high working temperatures, but flexibility to withstand pressure in the masterbatch manufacturing and spinning process where strong physical pressure exists is required.

Accordingly, it is preferable to mix melamine and urea in a weight ratio of 7:3 to 9:1. If it is out of the above range, there is a problem in that the heat resistance of the capsule is lowered.

Thereafter, the first solution and the second solution are mixed and stirred, and the emulsion polymerization and crosslinking reaction to prepare the capsules include an emulsion polymerization step of stirring by adding the first solution, the second solution, and an aqueous sodium hydroxide solution as a solvent; And by adding a weak acid containing acetic acid to adjust the acidity to neutral, and then reacting the cross-linking reaction may include the step of preparing a capsule.

Here, the emulsion polymerization step is preferably performed at pH 8 to 11, and the crosslinking reaction is preferably performed at pH 5 to 6. In forming the capsule, pH control is the most important factor during the crosslinking reaction, and as the pH approaches 5, a stable spherical capsule can be formed.

As a result, organic microcapsules having an average particle diameter of 0.1 to 1.5 μm can be prepared. The prepared organic microcapsules have excellent heat resistance with a weight reduction of 15% or less after treatment at 265° C. for 10 minutes.

On the other hand, the porous ceramic particles supporting the skin cosmetic active ingredient may be included in 0.5 to 5% by weight in the yarn. If the content of the porous ceramic particles in the yarn is less than 0.5% by weight, it may cause deterioration of skin beauty performance, and if it exceeds 5% by weight, spinning workability and deterioration of yarn properties may occur.

In addition, the porous ceramic particles may have an average particle diameter of 0.1 to 1.0 μm, preferably 0.1 to 0.7 μm, and more preferably 0.1 to 0.3 μm. When the average particle diameter of the porous ceramic particles is less than 0.1 μm, functional deterioration may occur, and when the average particle diameter exceeds 1.0 μm, a problem in fine spinning workability of single yarn fineness of 1 to 3 denier may occur.

Porous ceramic particles have the advantage that they can be used as carriers for cellulite decomposition promoting substances and moisturizing substances by using meso-sized pores and high surface area. It has the characteristic of being able to improve the diffusion rate and reaction rate of functional materials.

Non-limiting examples of such ceramic particles are silica-based or zeolite-based, preferably silica.

Thereafter, preparing a first masterbatch chip by melt-mixing the organic microcapsules and nylon prepared as described above; And it is possible to prepare a cosmetic nylon fiber through the step of spinning by melt-mixing the first masterbatch chip and the nylon chip.

On the other hand, before the spinning step, it may further include the step of preparing a second masterbatch chip by melt-mixing the porous ceramic particles and nylon carrying the skin cosmetic active ingredient. In this case, in the spinning step, the first masterbatch chip, the second masterbatch chip and the nylon chip may be melt-mixed and spun.

In the case of manufacturing cosmetic nylon fibers containing both organic microcapsules and porous ceramic particles, it is preferable to basically prepare two functional master batch chips, respectively.

This is also because the basic characteristics of organic and inorganic are different, and workability can be advantageous if both are made into one master batch chip at the same time, but each cosmetic characteristic is neutralized in some cases. In addition, it is also necessary to control the drying time by keeping in mind that cosmetic substances basically contain a lot of moisture.

When manufacturing the first master batch chip, high-viscosity nylon chips are used to improve spinning workability and physical properties degradation due to viscosity drop, and 10-30 wt% of organic microcapsules having an average particle diameter of 1.5 µm or less are mixed at 270-310 ° C. A first master batch chip is prepared by melt mixing with a single extruder or a twin extruder.

When manufacturing the second master batch chip, high-viscosity nylon chips are used to improve spinning workability and physical properties degradation due to viscosity drop, and 10-30 wt% of porous ceramic particles having an average particle diameter of 0.7 μm or less are mixed at 270-310 ° C. A second master batch chip is prepared by melt mixing with a single extruder or twin extruder.

In the mixing and melting step, the first master batch chip or the second master batch chip is supplied through the master batch chip silo, the general nylon chip is supplied to the nylon silo, and these are uniformly mixed using a separate metering and mixing supply device, Put it in the extruder and melt it. A pump is connected to the extruder to send the molten material to the spinning nozzle, and a polymer melting pump that melts the polymer material by heat is installed after the extruder.

The nylon spinning fiber of the present invention may be used by adding other modifiers such as far-infrared radiation ceramics, dispersing aids, polymer affinity aids, antioxidants, stabilizers, flame retardants, colorants, antibacterial agents, UV absorbers, and other modifiers and functional additives.

As described above, after mixing and melting the first masterbatch chip or the second masterbatch chip and the general nylon chip, it is spun by a spinneret mounted on a spin block. By using a different-section spinneret, flat yarns such as Samsan, Sasan, and Osan can be made.

The cooling step is a step in which the mixed melted polymer is spun by a spinning nozzle and then passed through a cooling device to cool it.

One of the cooling devices that can be used is that it uses a rotational outflow quenching (ROQ) and is equipped with a nozzle heating heater.

In the fiber drawing step, the cooled polymer is drawn using a first godet roller and a second godet roller to prepare a cosmetic nylon fiber having a single yarn fineness of 1 to 3 denier. That is, the first godet roller and the second godet roller may be stretched at a predetermined draw ratio and spun by a spin-draw yarn method, or may be added by manufacturing as a partially oriented yarn without stretching. A drawn yarn or a false twisted yarn may be manufactured through a drawing or a false twisting process, and it is preferable to prepare the partially oriented yarn as a draw textured yarn using a false twisting machine.

have. At this time, for uniform stretching, oiling may be performed by a focusing oiling device before the first godet roller. The yarn produced by the direct spinning method (SDY), the partially oriented yarn (POY) or the textured yarn (Draw textured yarn) manufacturing method is wound in a winding device. As mentioned above, the partially oriented yarn is manufactured and wound as a final drawn yarn or false twisted yarn through an additional drawing or false twist process.

The cosmetic nylon fiber prepared in this way preferably has a single yarn fineness (dpf) of 1 to 3 denier, and as such, there is an advantage that a functional material (skin beauty active ingredient) can be stably added according to the decrease of the single yarn fineness.

These cosmetic nylon fibers have a strength of 3.5 g/d or more, and an elongation of 35% or more, which can express the functionality of releasing active ingredients while maintaining basic fiber properties.

On the other hand, the organic microcapsule and the porous ceramic particles supporting the skin cosmetic active ingredient may be included in each 0.5 to 5% by weight in the yarn. When the content of the organic microcapsule and the porous ceramic particles is less than 0.5% by weight in the yarn, respectively, it may cause deterioration of skin beauty performance, and if it exceeds 5% by weight, respectively, spinning workability and deterioration of yarn properties may occur.
