Description
본 발명은 내구성, 항균성 및 생분해성이 우수한 수세미의 제조방법에 관한 것으로, 더욱 상세하게는 폴리우레탄 발포체를 편성물 내에 개재하여 우수한 내구성을 나타내며, 항균사와 항균제혼합물이 함유된 폴리우레탄 발포체가 사용되어 우수한 항균성을 나타낼 뿐만 아니라, 산화생분해 촉매가 사용되어 우수한 생분해성을 나타내는 수세미의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a scrubber having excellent durability, antibacterial properties and biodegradability, and more particularly, polyurethane foam is interposed in a knitted fabric to exhibit excellent durability, and a polyurethane foam containing antibacterial yarn and an antimicrobial agent mixture is used to provide excellent It relates to a method for producing a scrubber that exhibits excellent biodegradability by using an oxidative biodegradation catalyst as well as exhibiting antibacterial properties.
일반적인으로 식기의 표면에 뭍은 기름때나 음식물 찌꺼기 등을 제거하기 위해 수세미와 세제를 이용하여 닦아낸 후 다시 물로 세척하는 과정이 진행된다.In general, in order to remove oil stains or food residues adhered to the surface of dishes, a process of wiping them with a scrubbing brush and detergent and then washing them again with water is performed.
세척과정이 완료되면 사용한 수세미는 잔존하는 물기와 음식물 찌꺼기 등으로 인해 세균이 번식할 가능성이 높기 때문에, 사용 후에는 음식찌꺼기와 물기를 완전히 제거한 후 마른 상태가 유지되도록 보관하거나 또는 수시로 살균하는 등 위생적인 관리가 요구된다.After the cleaning process is completed, the used loofah is highly likely to breed bacteria due to remaining water and food debris. Appropriate management is required.
그러나 실제 각 가정에서는 대부분 수세미를 사용한 후에 손으로 물기를 짜서 싱크대 위에 올려놓는 방식으로 보관하다가 재사용하는 과정을 반복하게 되는데, 수세미는 함수성이 우수한 발포체(스펀지)로 이루어져 내부에 수분까지 제거가 어렵기 때문에, 세균증식의 위험성에 항상 노출되어 있다.However, in reality, most households repeat the process of storing and reusing a scrubbing brush by squeezing it out by hand and putting it on the sink after using it. The scrubber is made of a foam (sponge) with excellent moisture content, so it is difficult to remove moisture from the inside. Because of this, it is always exposed to the risk of bacterial growth.
상기의 문제점을 해소하기 위해 종래에는 수세미에 항균성을 부여하기 위해 발포체로 이루어진 수세미의 표면에 항균성을 나타내는 세라믹분말을 부착시키는 방법이 이루어지기도 하였으나, 이러한 방법은 수세미를 구성하는 발포체 내부까지 세라믹을 부착하기가 곤란하여 표면에만 세라믹이 부착되므로 세라믹에 의한 항균효과가 미미하고, 그 효과도 지속적으로 유지되지도 않는 문제점이 있으며, 수세미의 표면에 부착된 세라믹 성분으로 인해 식기에 스크래치가 발생하는 문제점이 있었다.In order to solve the above problems, conventionally, a method of attaching ceramic powder exhibiting antibacterial properties to the surface of a scrubber made of foam has been made to impart antibacterial properties to the scrubber, but this method attaches ceramic to the inside of the foam constituting the scrubber Since it is difficult to do so, ceramics are attached only to the surface, so the antibacterial effect of ceramics is insignificant, and the effect is not continuously maintained. there was.
또한, 종래의 수세미는 발포체를 사용하여 제조되기 때문에, 일정시간이 경과하면 쉽게 갈라지거나 심한경우 찢어지는 현상이 빈번하게 발생하여 내구성이 낮고, 사용 후에는 생분해성이 낮은 성분으로 이루어져 폐기가 곤란하고, 토양매립이나 해양투기 등을 통해 폐기처분하는 과정에서 미세플라스틱을 다량 발생시키는 문제점이 있었다.In addition, since conventional scrubbers are manufactured using foam, they are easily cracked after a certain period of time or in severe cases, tearing frequently occurs, resulting in low durability, and difficult to dispose of after use because they are composed of components with low biodegradability. However, there was a problem of generating a large amount of microplastics in the process of disposal through soil reclamation or ocean dumping.

본 발명에 따른 내구성, 항균성 및 생분해성이 우수한 수세미의 제조방법은 산화생분해 촉매가 함유된 합성수지사에 항균사를 혼섬하여 합연사를 제조하는 합연사제조단계(S101), 상기 합연사제조단계(S101)를 통해 제조된 합연사를 튜브형태로 편성하는 편성물제조단계(S103), 상기 편성물제조단계(S103)를 통해 제조된 편성물 내에 항균성 폴리우레탄 발포체를 삽입하는 발포체삽입단계(S105) 및 상기 발포체삽입단계(S105)를 통해 항균성 폴리우레탄 발포체가 삽입된 편성물을 일정한 길이로 절단한 후에 양 말단을 밀봉하는 수세미가공단계(S107)로 이루어진다.The method for manufacturing a scrubber having excellent durability, antibacterial properties, and biodegradability according to the present invention includes a plied-twisted yarn manufacturing step (S101) of preparing a plied-twisted yarn by mixing an antibacterial yarn with a synthetic resin yarn containing an oxidative biodegradation catalyst, and the ply-twisted yarn manufacturing step ( A knitted fabric manufacturing step (S103) of knitting the ply-twisted yarn prepared through S101) into a tubular shape, a foam inserting step (S105) of inserting an antibacterial polyurethane foam into the knitted fabric manufactured through the knitted fabric manufacturing step (S103), and the foam After cutting the knitted fabric into which the antibacterial polyurethane foam has been inserted through the insertion step (S105) to a certain length, a scrubber processing step (S107) of sealing both ends is performed.
상기 합연사제조단계(S101)는 산화생분해 촉매가 함유된 합성수지사에 항균사를 혼섬하여 합연사를 제조하는 단계로, 산화생분해 촉매가 함유된 합성수지사 100 중량부에 항균사 30 내지 70 중량부를 혼섬하여 이루어지는데, 상기와 같이 항균사가 혼섬되면 항균효과가 우수한 합연사를 제공할 수 있다.The ply-twisted yarn manufacturing step (S101) is a step of preparing a plied yarn by mixing antibacterial yarn with synthetic resin yarn containing an oxidative biodegradation catalyst, 30 to 70 parts by weight of antibacterial yarn per 100 parts by weight of synthetic resin yarn containing an oxidative biodegradation catalyst. It is made of mixed fibers, and when the antibacterial yarn is mixed as described above, a ply-twisted yarn having excellent antibacterial effect can be provided.
상기 합성수지사는 선형저밀도폴리에틸렌(linear low density polyethylene, LLDPE) 및 산화생분해 촉매로 이루어지는데, 선형저밀도폴리에틸렌 100 중량부 및 산화생분해 촉매 0.5 내지 1.5 중량부로 이루어지는 것이 바람직하다.The synthetic resin yarn is composed of linear low density polyethylene (LLDPE) and an oxidative biodegradation catalyst, and is preferably composed of 100 parts by weight of linear low density polyethylene and 0.5 to 1.5 parts by weight of an oxidative biodegradation catalyst.
이때, 상기 선형저밀도폴리에틸렌은 용융지수(ASTM D1238, 온도 190℃, 하중 2.16㎏)가 0.2 내지 3.0g/10분인 것이 바람직하고, 0.5 내지 1.5g/10분인 것이 더욱 바람직하다. 상기 선형저밀도폴리에틸렌의 용융지수가 0.2g/10분 미만일 경우 합연사로 제조된 편직물의 유연성이 저하되어 촉감이 저하될 수 있으며, 상기 선형저밀도폴리에틸렌의 용융지수가 3.0g/10분을 초과할 경우 합연사로 제조된 수세미의 기계적 물성이 저하될 수 있다.At this time, the linear low-density polyethylene preferably has a melt index (ASTM D1238, temperature 190 ° C, load 2.16 kg) of 0.2 to 3.0 g / 10 minutes, more preferably 0.5 to 1.5 g / 10 minutes. If the melt index of the linear low-density polyethylene is less than 0.2 g / 10 minutes, the flexibility of the knitted fabric made of ply-twisted yarn may deteriorate and the tactile feel may deteriorate, and if the melt index of the linear low-density polyethylene exceeds 3.0 g / 10 minutes Mechanical properties of a scrubber made of ply-twisted yarn may be deteriorated.
또한, 상기 선형저밀도폴리에틸렌의 밀도는 0.910 내지 0.930g/㎤인 것이 바람직하고, 0.915 내지 0.925g/㎤인 것이 더욱 바람직한데, 상기 선형저밀도폴리에틸렌의 밀도가 0.910g/㎤ 미만일 경우 제품의 합성수지사의 표면에 과도한 끈적임(sticky)이 발생하여 편성물을 제조하는 공정의 효율성을 저하시키고 수세미의 상품성을 저하시킬 수 있으며, 상기 선형저밀도폴리에틸렌의 밀도가 0.930g/㎤을 초과할 경우에는 제조되는 합연사로 제조된 편성물의 인열강도 등이 저하되기 때문에 바람직하지 못하다.In addition, the density of the linear low-density polyethylene is preferably 0.910 to 0.930 g / cm 3, and more preferably 0.915 to 0.925 g / cm 3. When the density of the linear low-density polyethylene is less than 0.910 g / cm 3, the surface of the synthetic resin yarn of the product Excessive stickiness may occur, reducing the efficiency of the process of manufacturing knitted fabrics and reducing the marketability of scrubbers, and when the density of the linear low-density polyethylene exceeds 0.930 g / cm This is not preferable because the tear strength and the like of the knitted fabric are lowered.

상기 산화생분해 촉매는 일정시간이 경과하면 합성수지사를 구성하는 선형저밀도폴리에틸렌의 분자사슬을 끊어지게 하여 생분해에 유리한 조건이 마련되도록 하며, 상기 선형저밀도폴리에틸렌의 분자사슬이 끊어진 후에는 자유라디칼이 생성되는데, 상기 자유라디칼은 빛(UV), 열, 수분 등과 같은 외부 환경 스트레스에 의해 히드로과산화물을 생성하여 분해가 가속화되며, 생성된 히드로과산화물은 토양 등에 존재하는 미생물 등에 의한 생분해가 진행되어 물, 이산화탄소 및 바이오매스 등으로 분해되기 때문에, 독성 잔여물질이나 미세플라스틱의 발생이 없이 우수한 효율로 생분해되도록 하는 역할을 하다.The oxidative biodegradation catalyst breaks the molecular chain of the linear low-density polyethylene constituting the synthetic resin yarn after a certain period of time to provide favorable conditions for biodegradation. After the molecular chain of the linear low-density polyethylene is broken, free radicals are generated. , The free radical generates hydroperoxide by external environmental stress such as light (UV), heat, moisture, etc., and decomposition is accelerated. Since it is decomposed into biomass, etc., it plays a role in enabling biodegradation with excellent efficiency without generating toxic residues or microplastics.
