Rope-Dyeing Soft Flow Machine with Horizontal Accumulation Vat.

MCS's Soft Flow (SF) series of dyeing machines are suitable for either low temperature or high temperature dyeing of knit and woven fabrics in rope form. The SF range includes four machines: SF 90, SF 99 Silk, SF 99, and SF 100. The SF 90, which was the first model to be introduced, features a flow jet transport system and a horizontal va..

Jigger Dyeing Machine.

Vald Henriksen's jigger dyeing machine is notable for its dosing unit that permits the use of isothermic dyeing processes and achieves a very high level of uniformity even when dyeing large lots. Speeds as high as 200 meters per minute are possible. These advantages make jigger dyeing competitive with continuous dyeing, particularly with ..

Experience of dyeing PES is Supercritical CO₂.

Amann && Sohne, a leading German supplier of polyester sewing threads, is investigating the commercial feasibility of dyeing in supercritical carbon dioxide. A pilot plant constructed by Josef Jasper operates at temperatures of up to 130 degrees centigrade and at pressures of up to 300 bars. Practical tests of the plant have produced ligh..

Colour aspects of soaping and washing of dyed fabrics

The colour difference of reactive dyed fabrics with several soaping agents and the colour change of them after washing were investigated using the L*, a*, b* uniform colour scale, to assess the effect of fluorescent brightening agents. In conclusion, little colour difference was observed between dyed fabrics soaped by nonionic surfactant,..

Decolourization of azo dye solutions by Fenton's oxidation

The reaction of azo dye active yellow lightfast 2 KT (AYL) with H₂O₂/Fe²+ system (Fenton's reagent) causes a drop in cololrization by 95-97％ at the minimum dosage of 17mg. 1-¹ H₂O₂. Intensification of the decolorization process is achieved under the influence of solar radiation or an increase in reaction temperature. The effectivenes..

Decolorization of continuous dyeing wastewater by ozonation

Ozone treatment to remove color from wastewater could be a solution to the problem of color pollution. All of the classes of dyes used in the textile industry are removed from wastewater to a certain extent, some poorly and others almost completely. Ozone also can aid in removing some other pollutants like surfactants and carriers that ar..

M.A.S.A completely new Siluro (torpedo)

Pozzi, is described. It can operated with very reduced bath ratios, eliminating dead space inside the autoclave. This produces savings of resources and also a more efficient circulation system and better dyeing. The three main innovative features of the apparatus are large diameter beams, pressurization by compressed air and 'lungs' for r..

Reducing effluent load in polyester lyeing

New dyes and chemicals which expand the colour range available while minimizing the environmental impact are discussed. BASF products which satisfy strict environmental requirements in the EU, the USA and Japan are listed. Ecologically harmless levelling agents, bioeliminable dispersants reusable rinsing liquors and after-clearing process..

염료이행 방지코팅 기술에 대해서

폴리에스테르 코팅가공포는 분산염료로 염색된 경우 다리미등의 열에 의해서 분산염료가 승화되어 다른 섬유 표면으로 이행되는 문제점을 가지고 있다. 이 현상은 승화성이 적은 염료를 사용하면 해결가능하지만 이 경우에도 코팅면을 매개체로 하여 분산염료의 이행오염은 발생된다. 가공공정중 코팅수지피막속의 분산염료의 이행오염기구를 조사한 결과 습식코팅의..

직물형태에 따른 폴리에스테르의 분산염료 염색성의 평가(Ⅰ)

양이온 염료로 염색 가능한 폴리에스테르(CDPET)는 통상의 폴리에스테르(NPET)와 구조가 다르기 때문에 염색성에도 차이가 난다. 이것을 이용해서 NPET 혹은 다른 합성섬유와 교직물을 만들면 이색염색이 가능해진다. 이 보고는 경사에 NPET, 위사에 CDPET를 이용한 교직물을 분산염료로 염색할 때, 열처리 및 염색조건의 영향에 대해서 검토하였다. 열처리된 시료를..
