Effect of cleaving and disinfecting agents on the colour fastness of textile floorcoverings

The demands made on carpets and floorcoverings are noted and methods of cleaning them are discussed. Cleaning and disinfecting agents and their chemical composition are considered. A chromatographic method is used to evaluate their effect. Carpets dyed with different dyes and by different methods are investigated. The results correlate we..

Recent advances in wool dyeing

Wool dyeing technology has made raid progress in recent years, spurred by the need for higher quality, quick response and greater environment care. Technological breakthroughs in other branches of science have also been applied to wool. Advances are summarized thus: dyeing with acid dyes; dyeing with metal complex dyes; dyeing with chrome..

Evaluating the fibre-protective effect of antisetting agents during the industrial dyeing of wool fabrics (AiF 12 322) (German) (Beurteilung der faserschutzenden wirkung von antisettingmitteln bei der industriefarbung von wollgeweben (AiF 12 322))

The advantages of the Basolan antisetting treatment during piece dyeing at the boil are assessed. Industrial dyeings of wool fabrics are made with two dyes (1:2 metal-complex and acid dyes) at different concentrations with and without antisetting agent. The effect of the Basolan method on hygral expansion, strength loss and the end-use pr..

Use of ultrasonics in the dyeing of narrow nylon textiles (AiF No. 12470 BG/1) (German) (Einsatz von ultraschall beim farben von schmaltextilien aus polyamid (AiF 12470 BG/1))

The effect of ultrasonics on the continuous dyeing of narrow nylon fabrics (ribbons) with acid dyes is investigated. It is found that the speed at which the fabrics pass through a mangle influences the ultrasonic treatment: continuous dyeing at low speeds at 80°C (0.5m/min) enhances the dyeing, whereas at 3m/min ultrasonics has no effect.

Improving the stability of wool textiles to light and gas fumes (AiF 12052 N) (German) (Erhohung der stabilitat von wolltextilien gegenuber licht und schadgasen (AiF 12052 N))

Attempts to improve the stability of wool to light and gas fumes after dyeing are described. Samples of wool dyed at a liquor ratio of 1:40 are treated with light stabilizers, reducing agents and special stabilizers and their stability to natural and artificial light and to ozone and oxides of nitrogen is investigated.

New ways of dyeing polypropylene (German) (Neue wege zur farbung von polypropylen)

A range of methods for dyeing polypropylene textiles as a commercial proposition is examined. This makes it possible to respond rapidly to changes in fashion and may make polypropylene textiles competitive on the fashion market. Before a breakthrough can be achieved on the market, the lightfastness of the textiles must be considerably imp..

Utilization of supercritical carbon dioxide for textile fabrics (Romanian) (Utilizarea dioxidului de carbon suprecritic in finisarea materialelor textile)

In this paper there are presented the possibilities of using the carbon dioxide for textile chemical finishing treatments. The usage of carbon dioxide is recommended from the environmental and toxicologic standpoints; the carbon dioxide I “clean” and it can be found in large quantities. In the first part of this paper you can find a def..

Enzymatic rinse process for reactives

The article summarizes the presentation made at the SDCANZ Symposium held in Melbourne recently by Gerry Gough of Bayer AG. The ERP System is a new enzymatic rinse process for reactive dyeings which is claimed to save water, time, energy and/or improve fastness. The system is targeted at dark shades, especially those based on Black 5. An ..

Utilization of supramolecular chemistry in order to obtain performance finishing effects (Romanian) (Utilizarea chimiei supramoleculare pentru obtinerea de efecte de finisare performante)

In this paper there are presented the results of some laboratory, technological and analytical researches regarding the possibility of β-cyclodextrine fixing and of one of its reactive compounds on a cellulose textile support, having in view the achieving of some further special finishing effects. Some references are made with respect to ..

A study on computer color matching system (Chinese)

Based on basic database, a new method is proposed in the program of computer color matching system. After running for many times, the program prove to be stable and reliable. The predicted recipes have little color difference comparing to the standard samples.
