이하, 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.
본 발명은 겔링성 및 투명도가 우수한 마스크팩용 부직포 시트 및 그 제조방법을 제공한다. 본 발명에 따른 마스크팩용 부직포 시트에는 대나무 부직포, 텐셀 부직포, 셀룰로오스 부직포 등 다양한 부직포가 사용될 수 있다.The present invention provides a nonwoven fabric sheet for mask packs with excellent gelling properties and transparency, and a method for manufacturing the same.

[조건 1][Condition 1]
T ≥ 90 %T ≥ 90%
(T는 400nm 부터 780nm 범위의 파장을 5nm 파장 단위로 하여, 10cm×10cm 부직포 시료에 주사했을 때의 분광 투과율(%)을 산술평균 낸 값을 나타낸다.(T represents the arithmetic average of the spectral transmittance (%) when scanning a 10cm
[조건 2][Condition 2]
겔링성 200% 이상Gelling property over 200%
상기 [조건 1] 및 [조건 2]를 만족시키는 것으로, 본 발명에 따른 마스크팩용 부직포 시트는 90% 이상의 가시광선 투과율을 만족시킨다. 따라서, 착용자가 본 발명에 따른 마스크팩용 부직포 시트로 제조된 마스크팩을 착용하는 경우, 마스크팩이 투명하기 때문에 착용자가 마스크팩을 착용하지 않은 듯한 느낌을 주어 심미감을 향상시킬 수 있다.By satisfying the above [Condition 1] and [Condition 2], the nonwoven fabric sheet for mask pack according to the present invention satisfies a visible light transmittance of 90% or more. Therefore, when the wearer wears a mask pack made of the non-woven fabric sheet for a mask pack according to the present invention, since the mask pack is transparent, the wearer feels as if he is not wearing a mask pack, thereby improving aesthetics.
[조건 1]은 KS K 0850에 따른 자외선 투과율 측정방법에서 측정방법은 동일하되, 파장 범위만 달리하여 측정한 것이다.[Condition 1] is the ultraviolet transmittance measurement method according to KS K 0850, but the measurement method is the same, only the wavelength range is different.
이하, 본 발명에 따른 마스크팩 시트의 제조방법에 대해 설명한다.Hereinafter, the manufacturing method of the mask pack sheet according to the present invention will be described.
본 발명에 따른 마스크팩용 부직포 시트의 제조방법은 텐셀 부직포를 수산화나트륨, 모노클로로아세트산나트륨의 혼합 수용액에 침지시키는 반응 단계; 반응단계 후 텐셀 부직포를 숙성시키는 숙성단계; 숙성된 텐셀 부직포를 수세하는 수세단계; 및 텐셀 부직포를 건조시키는 건조단계를 포함한다.The method of manufacturing a nonwoven sheet for a mask pack according to the present invention includes a reaction step of immersing a Tencel nonwoven fabric in a mixed aqueous solution of sodium hydroxide and sodium monochloroacetate; A maturation step of maturing the Tencel nonwoven fabric after the reaction step; A washing step of washing the aged Tencel nonwoven fabric; And a drying step of drying the Tencel nonwoven fabric.
수산화나트륨과 모노클로로아세트산나트륨의 혼합 수용액에 침지시키는 단계에서, 수산화나트륨은 6 내지 15 중량%, 7 내지 13 중량%, 8 내지 12 중량% 또는 9 내지 11 중량%가 될 수 있고 모노클로로아세트산나트륨은 5 내지 15 중량%, 7 내지 12중량%, 6 내지 12 중량% 또는 8 내지 9 중량%가 될 수 있다.In the step of immersing in a mixed aqueous solution of sodium hydroxide and sodium monochloroacetate, sodium hydroxide may be 6 to 15% by weight, 7 to 13% by weight, 8 to 12% by weight, or 9 to 11% by weight, and sodium monochloroacetate It can be 5 to 15%, 7 to 12%, 6 to 12% or 8 to 9% by weight.
수산화나트륨 및 모노크롤로아세트산이 상기 농도를 만족하는 것으로 본 발명에 따른 마스크팩용 부직포 시트는 가시광선, 자외선, 적외선의 투과율이 높아진다. 상기 농도를 벗어나는 경우 가시광선, 자외선, 적외선의 투과율에 현저한 차이가 발생한다. When sodium hydroxide and monochloroacetic acid satisfy the above concentrations, the nonwoven fabric sheet for mask pack according to the present invention has increased transmittance of visible light, ultraviolet rays, and infrared rays. If the concentration exceeds the above concentration, a significant difference occurs in the transmittance of visible light, ultraviolet rays, and infrared rays.
숙성단계의 온도는 30 내지 50℃ 또는 35 내지 45℃에서 진행될 수 있고, 숙성 시간은 10 내지 30 시간 또는 20 내지 25시간 동안 진행할 수 있다.The temperature of the ripening step may be 30 to 50°C or 35 to 45°C, and the maturation time may be 10 to 30 hours or 20 to 25 hours.
수세 단계는 1회 진행될 수 있으나, 2 내지 10개의 수세조를 순차적으로 거치며 진행될 수 도 있다. 구체적으로, 각 수세조에서의 수세단계는 수세용액의 온도를 달리하여 진행할 수 있다.The washing step may be performed once, but may also be performed sequentially through 2 to 10 washing tanks. Specifically, the washing step in each washing tank can be performed by varying the temperature of the washing solution.
예컨대, 5단계의 수세조를 이용하여 수세되는 경우, 수세 1단계는 27-33℃, 수세 2단계는 22 - 28℃, 수세 3단계는 22 내지 28℃, 수세 4단계는 22 내지 28℃ 및/또는 수세 5단계는 20 내지 30℃에서 진행될 수 있다. For example, when washing is performed using a 5-stage water bath, the 1st stage of washing is 27-33°C, the 2nd stage of washing is 22-28°C, the 3rd stage of washing is 22-28°C, the 4th stage of washing is 22-28°C, and /Alternatively, step 5 of water washing may be carried out at 20 to 30°C.
수세단계가 여러 수세조에서 순차 진행되는 경우, 수세조의 수세 용액 온도는 순차적으로 감소할 수 있다. 수세 용액의 온도가 순차적으로 감소하는 것으로, 부직포 시트의 열에 의한 변성을 방지할 수 있는 효과가 있다.When the washing steps are carried out sequentially in several washing tanks, the temperature of the washing solution in the washing tanks may sequentially decrease. By sequentially decreasing the temperature of the washing solution, there is an effect of preventing denaturation of the nonwoven fabric sheet due to heat.
수세단계에서, 적어도 하나의 수세조는 pH 7 이하의 용액으로 산 수세가 진행될 수 있다.In the washing step, at least one washing tank may be subjected to acid washing with a solution of pH 7 or lower.
건조 단계는 50내지 150℃, 120 내지 135℃, 60 내지 90℃ 또는 90 내지 110℃에서 진행되며, 건조 시간은 1 내지 30시간으로 진행될 수 있다. 건조 단계는 1 내지 2단계 또는 1 내지 3단계로 진행할 수 있으며, 각 단계에서의 건조 온도를 상이하게 설정할 수 있다.The drying step may be performed at 50 to 150°C, 120 to 135°C, 60 to 90°C, or 90 to 110°C, and the drying time may be 1 to 30 hours. The drying step can proceed in steps 1 to 2 or 1 to 3, and the drying temperature in each step can be set differently.
본 발명에 따른 마스크팩용 부직포 시트를 제조함에 있어서, 부직포는 대나무 부직포, 텐셀 부직포, 셀룰로오스 부직포 등이 사용될 수 있으며 그 외에도 다양한 부직포들이 사용될 수 있다. 또한, 한가지 섬유만 사용될 수도 있으나 수개의 섬유가 혼합되어 사용될 수도 있으며, 특히 장섬유 및 단섬유의 혼합으로 구성될 수도 있다. 장섬유는 지지역할을 하는 것으로 부직포의 강도를 올릴 수 있으며, 단섬유는 피부 밀착성을 높이는 효과가 있다. 구체적으로, 장섬유와 단섬유는 8:2 내지 6:4의 비율로 사용될 수 있으며, 5:5의 비율로 사용될 수도 있다. In manufacturing the nonwoven sheet for a mask pack according to the present invention, nonwoven fabrics such as bamboo nonwoven fabric, tencel nonwoven fabric, and cellulose nonwoven fabric may be used, and various other nonwoven fabrics may be used. In addition, only one type of fiber may be used, but several fibers may be mixed and used, and in particular, it may be composed of a mixture of long fibers and short fibers. Long fibers can increase the strength of nonwoven fabric by playing a supporting role, and short fibers have the effect of increasing skin adhesion. Specifically, long fibers and short fibers may be used in a ratio of 8:2 to 6:4, and may also be used in a ratio of 5:5.
