  • 새로운 기능성을 부여하기 위하여 여러 섬유를 사용하여 만든 복합소재 직물의 개발이 많아지고 있다. 복합소재의 염색가공에 있어서의 문제점은 복합소재를 구성하고 있는 섬유들의 물성과 염색성이 상이하여 동색성을 얻기가 힘들고 염료의 상대섬유 오염에 의해 견뢰도가 저하하는 것과, 구성섬유들의 수분과 열과 장력에 대한 반응이 틀려 구김이 발생하기 쉽다는 것 둥이다. (중략)

  • Carminic acid는 중남미 사막지대에 자생하는 선인장에 기생하는 연지충의 암컷을 분말로 만든 것으로 대표적인 anthraquinone계 천연 염재이다. 물, 알코올, 에테르에 쉽게 녹으며 금속과 안정한 킬레이트를 형성하여 약간의 심색화 및 농색화 현상이 일어난다. 또한 그 염색물은 일광, 습윤 견뢰도가 우수한 것으로 알려져 있다. Carminic acid는 산성매염염료의 구조를 가지고 있으며, 매염하지 않고 양모를 염색할 경우 산성염료와 비슷한 염색성을 나타낸다.(중략)

  • 폴리에스테르나 나일론의 세섬도 섬유를 사용한 소재가 실크와 같은 외관, 유연한 태 등의 감각적으로 우수한 특성을 가지기 때문에 최근에 섬유업계에서 큰 관심을 모으고 있다 이와 같은 세섬도 섬유는 부가가치를 높이기 위해 통상보다 복잡한 마무리 가공이 필요하며 염색가공에 있어서도 일반사 나일론보다 그 염색거동이나 견뢰도에 있어서 보다 엄격한 염료나 약품의 선택이 중요하다. (중략)

  • This research aimed at scrutinizing the dyeability of some solvent dyes on polyester and their light fastness to be exploited as a breakthrough in light fastness where utmost fastness is required such as ultramicrofibers and industrial markets. Dyeability on polyester was mainly evaluated by HT exhaust dyeing according to the general procedure. Light fastness has been tested by a preliminary UV test followed by HT xenon test in compliance with standard SAE J1885, 224 KJ. Fading has been determined quantitatively by evaluating the shade deviation and the strength difference between unexposed and exposed samples by means of CIELab values.

  • Dyeing properties of silk fabric on gromwell roof colorants were studied for the effect of dyeing conditions, such as methanol ratio, colorants concentration, pH, temperature and time etc. on the dye uptake and effect of mordants and mordanting methods on color change and dye uptake. And various colorfastnesses of dyed fabrics were evaluated far practical use. Gromwell colorants showed high affinity to silk and its isotherm adsorption curve was Freundlich type close to Nernst type. Therefore, it is considered that hydrogen bonding and Van der Waals force were involved in the adsorption of cromwell colorants to silk fabric. Post-mordanting method gave higher K/S value than other methods, but it was not significantly different color values from unmordanted one. Gromwell colorants produced mainly R and RP color depending on mordants and mordanting method. Dyed fabrics showed high colorfastness irrespective of mordanting treatment. Light colorfastness was increased for repeatedly dyed and Fe mordanted dyed fabrics.

  • Dyeing properties of the colorants from gromwell on cotton fabric were investigated. The effects of dyeing conditions on dye uptake and the effects of mordants and mordanting methods on K/S value, color change and colorfastness were explored. Gromwell colorants showed low affinity to cotton fabric, and its adsorption isotherm was Freundlich type close to Langmuir type. Therefore, it was considered that hydrogen bonding and Vander Waals force were involved in the adsorption of gromwell colorants to cotton fabric. Pre-mordanting method except Sn mordant gave higher K/S value but it was not significant. Gromwell colorants produced mainly R and RP color on cotton fabric depending on mordants and mordanting method. Dyed cotton fabric showed generally high colorfastness irrespective of mordanting treatment. Light colorfastness was increased by repeat dyeing and Fe and Sn mordanting.

  • Textile dyeing with vat dyes has the highest color fastness although one and the same dye of all vat dyes cannot always satisfy every color fastness requirement. So we examined cotton, nylon 6, and polyester fabrics dyed with vat dyes. Cotton, nylon 6 and polyester fabrics were dyed with vat dyes such as C. I. Vat Blue 1, Blue 19, Black 9, Green 1, Orange 2, and Violet 1 containing sodium hydrosulfite and NaOH. Oxidation were carried out by a sodium peroxoborate after dyeing. The dyed materials were soaped at the boil after oxidation. Especially hydrolysis and overreduction for dyed polyester with vats dyes containing -NHCO- and -NH- groups such as C. I. Vat Blue 6, Black 25, Black 27, Red 10, and Green 3 occurred. It seems that these phenomena are due to a high dyeing temperature. Wash and rubbing fastness of nylon are higher than that of cotton and polyester. Light fastness of cotton is higher than that of polyester and nylon.
