Nov 26, 2014· The reactive disperse dyes for printing cellulose fabric had good building up and better printing property. The light fastness, rubbing fastness and fastness to perspiration of the printed fabric were good. The reactive disperse dyes have potential application in cleaner production of printing cotton and cotton/polyester blend fabrics.
Jan 14, 2018· Dyeing of polyester with disperse reactive dyes 1. dyeing of polyester with disperse reactive dyes 2. Disperse dyes Characteristics i)Insoluble in water ii)It is an organic substance free of ionizing group iii)Dispersing agent is needed for dyeing iv)Wet and light fastness is good to excellent v)Molecular size is smaller as compared to other dyes vi)Disperse dyes are economical vii)Disperse ...
May 23, 2019· Reduction clearing is commonly carried out as an after-treatment to remove deposits of disperse dye and other residual impurities from the surface of dyed polyester. Because of certain environmental and economical disadvantages associated with traditional reduction clearing, there is industrial interest in alternative processes. In this study the P/C blended fabric was dyed with disperse dyes ...
Dyeing Of Polyester Fabric With Disperse Dyes (Carrier Method). Objects : To dye a material practically. To observe the practical advantages and disadvantages of this dye.
A series of temporarily solubilised reactive disperse dyes based on 1‐substituted derivatives of 2‐hydroxypyrid‐6‐one were applied to a 65;35 polyester/cotton blend using a one‐bath dyeing method without dispersing agent. The dyeing behaviour of these dyes on polyester and cotton fabrics, and polyester/cotton blend fabric, were studied.
Feb 01, 2013· disperse dyes[13] for dyeing of polyester/cotton blend. One-bath method for dyeing of polyester/cotton blends with reactive disperse dyes using supercritical carbon dioxide as a solvent at 393 K and 20 MPa was successfully investigated by Shingo et al. A very recent research work reported by Croft et al.[15] discussed the process of dyeing
May 10, 2019· Determine if your material is a polyester blend or polyester. If your items or fabric is a blend, you can dye your items in two processes if necessary. Dyeing the item twice, each time using the appropriate dye type for the fiber types in the polyester blend. Step 2: Select a Polyester Dye
Dec 01, 2013· When the polycotton fabric which had been dyed with both disperse and reactive dyes was washed-off using the two-stage bead wash-off for disperse dyes and the three-stage bead wash-off for reactive dyes, surplus dye was also removed, as shown by the reduced colour strength and higher lightness values . It is evident that similar levels of dye ...
Jan 14, 2013· Conculsions- 1.One bath dyeing of Polyester/cotton blend fabrics with reactive disperse dyes in successful with SC-CO2 .The optimum dyeing temperature and pressure are about 393 K and 20 Mpa respectively .
use the pc blended knitted fabric. In future if the fluorescent effect were fade it would be used as normal dyed fabric because of reactive and disperse dye. Normally dyeing of polyester/cotton blended fabric is dyed in two steps. The cost of double bath dyeing is quite higher than the one step or single bath dyeing.
This dyeing method of P/C blend fabric is dyed at two stages first is dyeing the polyester portion and then reduction clearing of fabric to remove the disperse dyes particle on the cotton portion ...
Item can remain in dye bath from 10 minutes up to one hour. If dyeing polyester or a polyester cotton blend, keep the fabric in the dye bath for at least 30 minutes to ensure that the color takes fully. Nylon tends to dye very quickly and much darker than other fibers so the actual time needed in the dye …
The reactive fluorescence yellow FL and disperse fluorescence yellow 10 GN are applied to dyeing of polyester/cotton fabrics. The effects of dyeing temperature, sodium carbonate, sodium chloride and dyes concentrations on K/S value of the dyeings are discussed, and the fluorescence effect and the color fastness of the dyeings are analyzed. The results show that the optimum dyeing process of ...
Selected mono and bifunctional reactive dyes were used in combination with the alkali-stable disperse dye for dyeing of polyester/cotton blend. Different dyeing methods for cotton and polyester ...
One-bath dyeing of polyester/cotton blends with reactive disperse dyes is investigated using supercritical carbon dioxide (SC-CO 2) as a solvent in the range of 353 to 393 K and 10 to 20 MPa. One-bath dyeing of polyester/cotton blends is successful. The dyeing behavior is compared with the thermosol dyeing method using the same dye.
dyeing process, disperse dyes penetrate to the amorphous region of polyester fibres. The cellulose component can be dyed with direct, reactive, vat, sulphur or azoic dyes, while polyester-cotton blends are mostly dyed with disperse and reac-tive dyes [3]. The polyester-cellulose blends are mostly dyed during a two-stage process:
Then we first dye the polyester part of the fabric with disperse dye here we used carrier method so 100°C is enough for dyeing polyester part. Then we dye the cotton part of the fabric with reactive dye here the temperature we used 60°C then some hot wash and cold rinsing is done to remove excessive dye molecule from the fabric surface.
fix the reactive dye unto the cotton. This was done for 30mins after which the fabric was removed, squeezed, thoroughly rinsed under a running tap and allowed to dry at room temperature. The polyester/cotton blend was also dyed with the disperse-reactive dyes …
Selecting Disperse Dyes for Polyester/Wool Blends. Sherill, William T. // Textile Chemist & Colorist;Oct78, Vol. 10 Issue 10, p15 . Consumer interest in the "natural look" has encouraged the growth of polyester/wool blends. Consequently, a larger number of dyehouses have become involved with this type of fabric.
Aug 30, 2020· Accordingly, disperse dyes that are used in Polyesters, are also projected to grow at a faster rate. The dyeing of cotton, modified previously by reaction with benzoyl chloride, has been carried out using disperse dyes in supercritical carbon dioxide at 100°C and 300 bar and compared with the dyeing of polyester under the same conditions.
