Description
본 발명은 면직물의 표백방법에 관한 것으로, 보다 상세하게로는 균일한 표백효과를 나타내는 면직물의 표백방법에 관한 것이다.The present invention relates to a bleaching method of cotton fabrics, and more particularly, to a bleaching method of cotton fabrics exhibiting a uniform bleaching effect.
통상 면직물의 표백은 가성소다세척-차아염소산소다표백-탈염소공정-과산화수소 추가표백 등과 같은 공정을 거치게 된다. 그러나 이러한 방법은 각 공정마다 표백할 제품을 세척한 후 재충전하여야 하므로 공정이 복잡하고 시간이 많이 소요되는 문제점이 있으며, 또한 염소계 표백제를 과도하게 사용하는 경우 불쾌한 냄새가 발생하는 문제점과 환경보존의 측면에서 바람직하지 못한 문제점이 있다. 이 외에 염소계 표백제에 의한 표백은 표백상태가 불균일하여 상품성을 저하시키는 문제점이 있다.Normally, the bleaching of the cotton fabric is subjected to a process such as caustic washing, hypochlorite, sodium bleaching, dechlorination, hydrogen peroxide addition, and the like. However, this method has a problem that the process is complicated and time-consuming since the product to be bleached must be washed and refilled at each process, and an unpleasant odor occurs when the chlorine-based bleach is used excessively and aspects of environmental conservation There is an undesirable problem with. In addition, bleaching with chlorine-based bleaching agent has a problem in that the bleaching state is uneven and thus deteriorates the commerciality.
본 발명은 상기한 바와 같은 문제점을 해결하기 위한 것으로, 공정이 단축된 면직물의 표백방법을 제공하는 것이다. 본 발명의 다른 목적은 균일한 표백효과를 나타내는 표백방법을 제공하는 것이다. 본 발명의 또 다른 목적은 인체와 환경에 유해한 염소계 표백제의 사용을 최소화하는 것이다.The present invention is to solve the problems described above, to provide a bleaching method of cotton fabric shortened process. Another object of the present invention is to provide a bleaching method having a uniform bleaching effect. Another object of the present invention is to minimize the use of chlorine bleach that is harmful to humans and the environment.
본 발명은 원통회전형 표백조에 직경 2∼5cm인 합성수지 재질의 볼을 표백할 제품과 함께 투입한 다음, 표백조 내부를 60∼90℃의 온도로 가온한 후, 가성소다세척 공정을 거치고, 이어서 과붕산나트륨을 투입하여 표백하는 것으로 구성된다.In the present invention, a ball of synthetic resin material having a diameter of 2 to 5 cm is added to a cylindrical rotary bleach tank together with a product to be bleached, and then heated inside the bleach tank at a temperature of 60 to 90 ° C., followed by caustic soda washing process. It consists of bleaching with sodium perborate.
이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명에서 사용되는 합성수지 재질의 볼은 표백조가 회전할 때 발생하는 원심력에 의하여 표백할 제품을 두드려 주는 역할을 하게 된다. 그 동안 표백효과를 높히기 위하여 일반적으로 사용되어 온 자연산 부석에 비하여 내약품성과 내마모성이 우수하여 반영구적으로 사용될 수 있으며, 특히 폐수의 배출이 없으므로 생산원가를 크게 줄일 수 있다. 특히, 고속회전시 발생되는 원심력에 의하여 볼이 표백조에 부딛힐 때 발생되는 충격을 자연산 부석에 비하여 크게 줄일 수 있으므로 기계의 수명을 연장시킬 수 있다.Synthetic resin ball used in the present invention serves to tap the product to be bleached by the centrifugal force generated when the bleaching tank rotates. It can be used semi-permanently because of its excellent chemical resistance and abrasion resistance compared to the natural pumice which has been generally used to increase the bleaching effect. In particular, there is no discharge of waste water, thus greatly reducing the production cost. In particular, the impact generated when the ball hits the bleach tank by the centrifugal force generated during the high-speed rotation can be greatly reduced compared to the natural pumice, thereby extending the life of the machine.
볼의 직경이 상기 범위보다 클 경우에는 균일한 표백효과를 기대할 수 없고, 상기 범위 미만의 경우에는 표백 보조효과가 부족하게 된다.If the diameter of the ball is larger than the above range, a uniform bleaching effect cannot be expected, and if it is less than the above range, the bleaching auxiliary effect is insufficient.
본 발명에서 사용되는 가성소다는 표백될 제품을 연화시켜 주는 역할과 동시에 표백제의 표백효과를 향상시키는 역할을 하게 된다. 적절한 사용량은 표백조 내의 pH가 10∼12정도 유지될 수 있는 정도이다.The caustic soda used in the present invention softens the product to be bleached and at the same time serves to enhance the bleaching effect of the bleach. Appropriate amounts of use are such that the pH in the bleach bath can be maintained between 10 and 12.
본 발명에서 사용되는 과붕산나트륨은 인체와 환경에 무해하면서도 우수한 표백효과를 발휘한다. 또한 분말상이지만 수분에 안정적이고 저장성이 좋아서 공정에 편리하게 적용시킬 수 있다. 종래에 많이 사용되어 온 차아염소산나트륨과 비교할 때 가격이 높은 단점은 가지고 있으나, 균일한 표백효과를 부여할 수 있는 점과 인체와 환경에 무해하다는 장점을 가지고 있다. 특히 본 발명에서 사용되는 합성수지 볼과 함께 사용될 경우에는 더욱 우수한 표백효과를 나타낸다. 적절한 사용량은 표백조에 투입되는 물 1리터당 0.5∼10g이다. 표백시간은 사용되는 제품의 재질에 따라 차이가 많이 나며 통상 0.3∼4시간이다.Sodium perborate used in the present invention exhibits an excellent bleaching effect while being harmless to humans and the environment. In addition, it is powdery but stable to moisture and has good shelf life, and thus can be conveniently applied to a process. Compared with sodium hypochlorite, which has been used a lot in the past, the price has a high disadvantage, but it has the advantage of giving a uniform bleaching effect and harmless to the human body and the environment. In particular, when used in conjunction with the synthetic resin ball used in the present invention shows a more excellent bleaching effect. Appropriate amounts of use are 0.5 to 10 g per liter of water added to the bleach bath. The bleaching time varies greatly depending on the material of the product used and is usually 0.3 to 4 hours.
본 발명의 실시예는 아래와 같다.An embodiment of the present invention is as follows.
<실시예><Example>
직경 1.2 M인 실험용 회전원통형 표백조에 물을 가하고 가성소다를 첨가하여 pH가 11이 되도록 조절하였다. 여기에 직경 3cm의 합성수지 볼 50개와 표백할 제품으로 청바지를 넣고 10분간 표백조를 회전시킨 다음, 과붕산나트륨을 0.5중량부 가하여 다시 50분간 회전시켰다. 이후 탈수 및 수세하여 표백된 제품을 얻었으며, 얻어진 제품은 관능평가결과 촉감과 표백의 균일성이 양호하였다.Water was added to an experimental rotary cylindrical bleach tank with a diameter of 1.2 M and caustic soda was added to adjust the pH to 11. Here, 50 synthetic resin balls having a diameter of 3 cm and jeans were put into the product to be bleached, and the bleaching tank was rotated for 10 minutes, and then 0.5 parts by weight of sodium perborate was added and rotated again for 50 minutes. Then, dehydrated and washed with water to obtain a bleached product, and the obtained product was good in touch and bleaching uniformity as a result of sensory evaluation.
<비교예 1>Comparative Example 1
실시예와 동일하게 시행하되, 합성수지 볼을 사용하지 아니 하였다. 얻어진 제품은 표백이 불균일하게 이루어졌으며, 또한 표백상태가 불충분하였다.The same procedure as in Example, but did not use a synthetic resin ball. The obtained product was unevenly bleached and also insufficiently bleached.
<비교예 2>Comparative Example 2
실시예와 동일하게 사용하되, 합성수지 볼의 직경이 6cm인 것을 사용하였다. 얻어진 제품은 표백상태는 충분하였으나 표백이 불균일하였다.Used in the same manner as in Example, the diameter of the synthetic resin ball was used 6cm. The product obtained had a sufficient bleaching condition but a non-bleaching condition.
<비교예 3>Comparative Example 3
실시예와 동일하게 시행하되, 합성수지 볼의 직경이 1cm인 것을 사용하였다. 얻어진 제품은 표백은 균일하였으나 표백상태가 불충분하였다.The same procedure as in Example, the diameter of the synthetic resin ball was used 1cm. The product obtained had a uniform bleach but insufficient bleaching.
이상의 실시예를 통하여 알 수 있는 바와 같이, 본 발명에 의하여 표백공정이 단축되며, 표백효과가 우수하고 표백의 균일성이 양호한 면직물을 얻을 수 있다. 또한 인체 및 환경에 유해한 염소계 표백제의 사용을 최소화할 수 있는 효과를 발휘한다.As can be seen through the above embodiment, the present invention can shorten the bleaching process, it is possible to obtain a cotton fabric having excellent bleaching effect and good uniformity of bleaching. In addition, it has the effect of minimizing the use of chlorine bleach harmful to humans and the environment.
