Description

카제인 함유 천연염색 고착제 및 천연염색 방법{natural dyeing method}Casein-containing natural dye fixing agent and natural dyeing method

본 발명은 카제인 함유 천연염색 고착제 및 천연염색 방법에 관한 것으로서, 더욱 상세하게는 밀크 카제인, 계란 흰자, 콩 단백질 및 천연아교 중에서 선택되는 어느 하나의 카제인 분말 85~90 중량%, 탄산수소나트륨 10~15 중량% 및 초산으로 이루어진 천연염색 고착제와 이를 사용한 염색방법에 관한 것이다.The present invention relates to a casein-containing natural dye fixing agent and a natural dyeing method, more specifically, any one casein powder 85 ~ 90% by weight selected from milk casein, egg white, soy protein and natural glue, sodium hydrogen carbonate 10 ~ It relates to a natural dye fixing agent consisting of 15% by weight and acetic acid and a dyeing method using the same.

단백질은 기원전부터 사용해온 물질로 우리의 의식주 생활 속에 다양한 방법을 통해 직간접적으로 널리 이용했다. 전통 천연염색은 다양한 색을 섬유 등에 염착시켜 사용하고 있다. 염료를 섬유 등에 염착시키기 위해서는 우유, 콩즙, 석회, 철, 동, 알미늄, 아교, 잿물 등의 다양한 광물, 동물, 식물성을 이용한 전통 천연 매염재를 사용하여 염색 견뢰도를 높이고 있다. 다양한 매염재 중에 단백질이 염료를 고착시켜 견뢰도를 높여주는 역할을 한다.Protein is a substance that has been used since BC, and has been widely used directly and indirectly in various ways in our life. Traditional natural dyeing is used by dyeing various colors in textiles. In order to dye dyes into textiles, dyeing fastness is increased by using traditional natural mordants using various minerals such as milk, soybean, lime, iron, copper, aluminum, glue, lye, animal and vegetable. Among various mordants, the protein sticks the dye to increase the fastness.

오랜 염색을 해온 전통 염장인들은 염료의 숙성정도를 조절하고 매염재 제조 조건을 맞추어 흡착도를 높이는 숙련된 기술을 가지고 있다. 일반 염색인들은 보편적인 방법이나 화학적 매염재를 이용해 염색을 하여 사용하고 있다. 전통 천연염색은 염료의 온도, 숙성, 발효 등의 조건과 매염재의 물, 온도, 습도, 숙성도 등을 맞추기 어려워 견뢰도 높은 염색은 전문 염장인들이 가능하고 일반 염색인들은 어려운 편이다. 염색 시 피염물에 염료가 잘 흡착되어 견뢰도 높은 염색이 되어 실용성이 높아야 한다. 현재까지 전통 천연염색은 견뢰도를 잘 해결하지 못한 것이 문제점이다.
Traditional dyeers who have been dyeing for a long time have the skill to adjust the degree of aging of dyes and to increase the adsorption rate by adjusting the condition of making mordant. General dyeers use a common method or dyeing using chemical mordant. Traditional natural dyeing is difficult to match the conditions such as dye temperature, ripening, fermentation, and water, temperature, humidity, and maturity of mordant, so high-speed dyeing is possible for professional dyeers and general dyeers are difficult. When dyeing, dye should be well adsorbed to the dye to be fastened with high fastness and high practicality. Traditional natural dyeing has not been able to solve the fastness well.

When 40 g of casein powder and 5 g of sodium hydrogen carbonate are mixed and stirred well in 1 L of water (about 70 to 100 ° C.), the solution is completely dissolved to obtain a casein aqueous solution. 300 g is appropriate. Add the salt to the aqueous casein solution, knead lightly, squeeze, and shake. After the brine is grown, acetic acid is added to the aqueous casein solution to adjust the pH to about 4.5-5. Add the brine again to the aqueous casein solution and knead it for about 30 minutes. Coagulation between the salts, the natural dyes and the casein triad occurs. Squeeze the salt to dry lightly. Heat dried (ironed) well-dried salts. Through the above process, the dye is transformed into a perfect natural dyeing product with high color fastness. The wash fastnesses of the stain after the post-dyeing dyeing process were greatly improved to 4-5.
