Effects of the dye distribution in nylon fibers on the dyeing color yield and fastness properties

Laboratory trials have shown that the 'Infinity' dyeing method for acid dyes on nylon offers a higher color yield, a shorter dyeing time, and 100％ exhaustion with little or no added auxiliary chemicals. It is thus a more environmentally friendly process than the conventional exhaust dyeing method. The fastness to washing, daylight and oz..

Dyeing and printing of Basofil fabrics (German) (Farben und Bedrucken von Basofil Geweben)

Basofil, a new BASF synthetic fiber based on a melamine resin, is characterized by high thermal endurance, flame retardancy, and good insulation properties. The fiber has found widespread use in the form of fabrics and nonwovens for heavy-duty heat-and fireproofing and for air travel and transport. A further field of application based on ..

On the process research of dyeing and finishing of microfibre, low tex R/T blended fabric (Chinese)

Intermittent processing and short-run production equipment is normally used for the dyeing and finishing of microfibre fabric. Continuous production equipment is rarely used to do this. In order to study the possibility of using continuous dyeing and finishing for the production of low tex fabrics made of microfibres of viscose rayon and ..

Innovative new product for afterclearing polyester in the dyebath

In this paper a new afterclearing agent for use in polyester dyeing, launched recently by BASF AG, Germany, is described. The product, Cyclanon TX 5179, is claimed to give high wash fastness as well as a 30％ saving in time, a 40％ saving in water consumption and significanlty reduced environmental pollution. Details are given on its use ..

Rope dyeing (Italian)

The advantages of the Multiflow single rope dyeing machine developed by the Italian firm MCS are described. The Multiflow ensures uniformity and repeatability for the following reasons: the single rope system gives maximum uniformity, precise control of passage time (one-time only), low value of machine load/pump capacity ratio, high numb..

ITS-charts: jet dyeing machine

These charts describe several different makes of jet dyeing machines. They include details of their pump type/capacity, control equipment and fault indicator as well as the type of model and the features it promotes.

Design of jig's new control system and utilization of regenerated energy

In this paper, the design of the jig's control system and technology which circularly utilize regenerated energy was introduced. The control principle of two important factors: uniformly liner velocity and constant tension during jig operating were analysed.

New possibilities in dyeing: an approach to handle energy and environmental issues

The conventional method of dyeing cellulosic materials essentially requires chemical assistants such as salt and alkali for the exhaustion and fixation of anionic dyes. The dyeing of cellulosic blends with polyester for example necessitates operation in t

On the elimination of color differences in the same dye liquor about the combination fabric of worsted silk and wool (Chinese)

The difference in structure between silk and wool mean that color differences with occur in dyeing. This paper describes the dyeing process conditions needed in order to eliminate the color differences when dyeing combination worsted silk and wool fabrics in the same liquor.
