Description

Soap for silk fabric manufacturing and its manufacturing method {THE SOAP FOR SILK TEXTILE PRODUCTION AND MANUFACTURING METHOD OF THAT}

본 발명은 실크직물 제조용 비누와 그 제조방법에 관한 것이다.The present invention relates to a soap for producing silk fabrics and a method for producing the same.

실크직물은 누에고치부터 만들어진 실을 직물형태로 짜낸 천연 섬유이다.Silk fabrics are natural fibers that weave from silkworm cocoons into fabrics.

실크직물의 생산공정은 양잠, 조사(操絲), 제직, 정련, 염색, 가공 공정으로 이루어진다.The production process of silk fabrics consists of snoozing, irradiation, weaving, refining, dyeing and processing.

양잠은 누에를 길러 고치를 만들기까지의 과정을 말한다.Sheep sleep is the process of raising silkworms to make cocoons.

누에고치에서 실을 뽑는 공정을 '조사'라고 한다. 건조된 누에고치를 90 ~ 100 ℃의 뜨거운 물에 삶으며 생사를 뽑는다. 뽑아낸 생사의 표면은 공기 중에서 산화되어 23 ~ 27 % 의 세리신(Sericin)이 보호막처럼 싸고 있어 광택이 없이 뻣뻣하다. 표면을 싸고 있는 이 세리신을 비눗물 등으로 세탁하여 제거하면 피브로인(Fibroin)이 주로 남아 실크 특유의 광택과 촉감이 나오게 된다.The process of pulling the thread from the cocoon is called 'investigation'. Dried cocoon is boiled in hot water of 90 ~ 100 ℃ and extract the raw silk. The surface of the extracted raw sand is oxidized in the air, and 23 to 27% of sericin is wrapped like a protective film, which is matt and stiff. If the sericin covering the surface is washed with soapy water and removed, fibroin remains mainly to give silk's unique luster and feel.

조사공정에서, 세리신을 너무 적게 빼면 옷감이 뻣뻣하게 되고, 너무 많이 삶으면 표면이 피어버리고 얼룩이 지게된다. 따라서 세리신을 적절히 제거하는 비누가 필요하다.In the irradiation process, if too little sericin is removed, the fabric will be stiff, and if too much boiled, the surface will bloom and stain. Thus, soap is needed to properly remove sericin.

생사에서 세리신이 제거된 것을 직기에서 제직하여 생지를 짠다.The sericin is removed from raw silk and weaved in a loom to squeeze dough.

짜여진 생지는 뻣뻣하고 거칠어 이를 부드럽고 광택이 나는 실크로 만들기 위해 비누 등의 알칼리용액에서 4 시간 정도 삶아 원단을 만들며, 이 과정을 정련이라 한다.Woven dough is stiff and coarse to make it soft and shiny silk, which is then boiled for 4 hours in alkaline solution such as soap to make a fabric. This process is called refining.

정련된 원단은 염색하거나 나염을 한다.Refined fabrics are dyed or printed.

염색을 마친 실크 원단은 샌드워시가공, 신축가공 등의 방법으로 가공하여 실크 직물을 만들어 사용한다.Dyed silk fabrics are processed by sandwashing and stretching to make silk fabrics.

위와 같이 실크직물을 제조하는 과정에서 조사공정과 정련공정에서 비누를 사용하여 세탁한다.In the process of manufacturing the silk fabric as described above is washed using soap in the irradiation process and refining process.

그런데, 기존의 일반 세탁비누를 사용할 때 세리신이 잘 빠지지 않거나, 정련한 제품에 흠집이 생기거나 품질이 고르지 못한 등의 문제점이 있었다.However, when using the conventional general laundry soap, sericin does not fall well, or there is a problem such as scratches or uneven quality of the refined product.

한편, 비누를 제조하는 기존의 방법에는 유지 또는 지방산을 수산화나트륨 수용액과 함께 가열한 후 충분히 비누화 한 후 식염을 가해 하층의 폐유은 버리고, 상층에 분리된 용액으로 비누를 제조하는 염석법이 있으나, 이 경우 폐유가 다량 발생하는 문제점이 있었다.On the other hand, the existing method of manufacturing soap has a salting method of preparing the soap in a solution separated in the upper layer, discarding the waste oil of the lower layer by heating the fat or fatty acid with an aqueous sodium hydroxide solution and saponifying enough saline, There was a problem that a large amount of waste oil occurs.

Prepare an aqueous sodium hydroxide solution so that the same amount of water as the 20% by volume aqueous sodium hydroxide solution was removed from the impurities and put in a prepared fat and heated for 2 to 3 hours without stirring, and then again the remaining sodium hydroxide solution After adding 80% by volume of the aqueous solution over 30-40 times and heating to 85-95 ° C. with stirring for 2-3 hours, palm oil kernels were added to 4.5-4.7% by weight of the reactants. Was stirred for 3-4 hours consists in preparing a soap solution, a soap sikhyeoseo prepared was poured in a plastic mold for molding a soap solution prepared so until.

이때 각 원료별 배합비는 해당 비누의 특성을 유지하는 통상의 범위 내에서 가감이 가능하다.At this time, the compounding ratio for each raw material can be added or subtracted within the usual range to maintain the properties of the soap.

본 발명의 실크직물 제조용 비누의 조사공정용 비누는 생사에서 세리신을 효율적으로 제거하기 위해 미강유와 경화유의 비율을 8 : 1 내지 9 : 1의 비율로 혼합하여 제조한다.Soap for irradiation process of the silk fabric manufacturing soap of the present invention is prepared by mixing the ratio of rice bran oil and hardened oil in a ratio of 8: 1 to 9: 1 in order to efficiently remove sericin from raw sand.

본 발명의 실크직물 제조용 비누의 정련공정용 비누는 뻣뻣한 상태의 생지를부드럽고 광택이 나는 원단으로 만들기 위하여 미강유와 경화유의 비율을 2 : 1 내지 3 : 1의 비율로 혼합하여 제조한다.Soap for the refining process of the soap for producing silk fabrics of the present invention is prepared by mixing the ratio of rice bran oil and hardened oil in a ratio of 2: 1 to 3: 1 in order to make a soft and shiny fabric in a stiff state.

본 발명의 비누 제조시에 사용한 원료들의 특성은 다음과 같다.The properties of the raw materials used in the soap production of the present invention are as follows.

면실유는 목화씨의 겉껍질을 벗기고 쪄서 짠 기름으로 식용유로 쓰이거나 마가린, 샐러드 기름, 경화유, 비누 등의 원료로 쓰인다. 면실유는 불포화 지방산으로서 이중결합이 한 개인 올레익산(Oleic acid)과 이중결합이 두 개인 리놀레익산(Linoleic acid)으로 이루어져 있어, 비누 제조시에 용해성이 크고, 세척력과 기포성이 크게 해준다.Cottonseed oil is peeled and steamed cottonseed oil and used as cooking oil or as raw material for margarine, salad oil, hardened oil and soap. Cottonseed oil is an unsaturated fatty acid consisting of oleic acid with one double bond and linoleic acid with two double bonds, so that it is highly soluble in soap production, and has great washing and foaming properties.

팜유는 식물성 기름인데도 포화지방산을 다량 함유하고 있고, 고열에서 안정성이 뛰어나며 산패과정이 더디다. 주성분은 탄소수가 16 개인 팔미틱산(Palmitic acid)이다. 따라서 팜유는 세척력이 크고 안정성이 크며, 비누 제조시에 사용하면 일반 비누와 달리 가열시에도 녹지 않고 비누형태와 기능을 유지시키는 기능을 한다.Palm oil is vegetable oil, but it contains a large amount of saturated fatty acid. It has excellent stability at high temperatures and slows the rancidity. Its main ingredient is palmitic acid, which has 16 carbon atoms. Therefore, palm oil has a great cleaning power and stability, and when used in soap production, unlike ordinary soap, palm oil does not melt upon heating and maintains a soap form and function.

야자유는 탄소수가 12 개인 라우릭산(Lauric acid)이 주성분이며 지방산의 포화도가 높고 요오드가(lodine value)가 낮아 내광성과 내열성이 좋은 기름이며, 용해도와 안정성이 큰 비누를 제조할 수 있게 한다.Palm oil is composed of lauric acid with 12 carbon atoms as its main ingredient. It has high saturation of fatty acid and low iodine value, so it has good light and heat resistance and makes soap with high solubility and stability.

미강유는 쌀겨를 짜서 만든 기름으로 약품, 비누, 도료, 화장품 등의 원료로 쓰인다. 미강유의 주성분은 불포화 지방산인 올레익산(Oleic acid)과 리놀레익산(Linoleic acid)이다. 따라서 비누제조시에 미강유를 사용하면 용해성이 크고, 세척력과 기포성이 큰 고급 비누를 제조할 수 있다.Rice bran oil is made by squeezing rice bran and is used as a raw material for medicines, soaps, paints, and cosmetics. The main components of rice bran oil are unsaturated fatty acids oleic acid and linoleic acid. Therefore, the use of rice bran oil in the manufacture of soap can produce a high-quality soap having high solubility, high cleaning power and high bubbleability.

경화유는 콩기름 등의 액상기름에 수소를 첨가하여 굳힌 백색의 인조지방으로써, 불포화 지방산을 포화지방산으로 변화시켜 녹는점이 높아져서 상온에서 고체가 되게 하는 성질을 갖는다.Cured oil is a white artificial fat hardened by adding hydrogen to liquid oils such as soybean oil, and has a property of changing unsaturated fatty acid to saturated fatty acid to increase melting point to become solid at room temperature.

우지는 포화 지방산으로 탄소수가 18 개인 스테릭산(Stearic acid)이 주성분이다. 따라서 비누 제조시 안정성이 크고, 세척력과 기포성이 큰 비누를 제조 할 수 있게 한다.Uji is a saturated fatty acid with 18 carbon atoms, steric acid. Therefore, it is possible to manufacture a soap with high stability, high cleaning power and high foamability during soap production.

수산화나트륨은 비누 제조시 지방산을 중화시키는 역할을 하며, 수산화나트륨 수용액의 첨가량과 넣는 방법에 따라 비누를 약 알칼리성 내지 중성으로 만들 수 있다.Sodium hydroxide neutralizes fatty acids during soap production, and depending on the amount of sodium hydroxide solution added and how it is added, the soap may be made slightly alkaline to neutral.

본 발명의 실크직물 제조용 비누를 개발하기 위해, 본 발명자는 수많은 실험과 결과분석을 통하여 본 발명을 완성하였다. 즉, 본 발명의 비누를 제조하는데 있어서, 각 원료의 종류 선택과 적정 배합비율과, 조건 등에 따라 수많은 경우의 수가 발생하는데, 본 발명의 발명자가 수많은 실험과 아이디어을 동원하여 만들어낸 발명으로, 이와 같은 발명은 당업자가 기존에 알려진 내용을 조합하여도 용이하게 발명할 수는 없는 것이라 하겠다.In order to develop a silk fabric soap of the present invention, the present inventors completed the present invention through a number of experiments and results analysis. That is, in manufacturing the soap of the present invention, a number of cases occur depending on the type of each raw material, the appropriate blending ratio, the conditions, and the like, and the inventors of the present invention have created a lot of experiments and ideas. The invention may not be easily invented by those skilled in the art in combination with the known content.

이하 본 발명을 실시예를 들어 상세히 설명하나 이들이 본 발명의 범위를 제한하는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples, but these examples do not limit the scope of the present invention.
