摘要:
The present invention relates to a process for producing dyed mixed fibres (D-MF), dyed mixed fibre yarns (D-MY) and/or dyed mixed fibre textile fabrics (D-MT) in which mixed fibres (MF), mixed fibre yarns (MY) and/or mixed fibre textile fabrics (MT) comprising at least one polyester fibre (PF) and at least one further fibre (FF) are simultaneously contacted with at least two different dyes (D1) and (D2) at a temperature TD
摘要:
The present invention relates to disperse azo dyes of formula wherein R1 is bromo, nitro, cyano, methyl, methoxy or trifluoromethyl; R2 is hydrogen, chloro, bromo or trifluoromethyl; R3 is hydrogen, chloro, bromo, methoxy, trifluoromethyl, nitro or cyano; and R4 is methyl, ethyl, n-propyl, 2-methoxyethyl, methoxycarbonylmethyl or 2-methoxycarbonylethyl; with the proviso that R1 is cyano in case R2 denotes chloro or bromo, to a process for the preparation of such dyes and to their use in the dyeing or printing of semi-synthetic and, especially, synthetic hydrophobic fibre materials, more especially textile materials.
摘要:
A method of pre-treating a polyester textile for inkjet printing with a water-based disperse dye ink composition, which method comprises treating at, least a part of, a surface of the polyester textile to increase its hydrophobicity.
摘要:
The invention refers to a disperse black ink comprising: an aqueous vehicle and a black dye dispersion comprising: disperse blue 165, disperse orange 29, disperse red 82 and disperse blue 60, and the use of such black ink in a method for inkjet-printing on a fabric.
摘要:
An example of an inkjet ink for textile printing includes a self-dispersed pigment. The self-dispersed pigment includes a pigment and an organic group attached thereto, the organic group including at least one phosphorus-containing group. The inkjet ink also includes a poly-ester-polyurethane binder and a liquid vehicle. The inkjet ink may be used in a printing method and/or in a textile printing kit.
摘要:
A different shrinkage composite yarn and preparation method. The modified polyester is spun with a porous spinneret to produce a different shrinkage composite yarn, and the spinneret holes on the porous spinneret are arranged in an elliptical arrangement. The different shrinkage composite yarn is obtained by winding modified polyester POY yarn and FDY yarn, network recombining, and coiling them. The preparation method of modified polyester is as follows: terephthalic acid reacts with ethylene glycol to produce ethylene terephthalate. The modified polyester is obtained by the reaction of terephthalic acid with branched diol. The fiber of the invention has good properties and the deviation rate of fiber density. The CV value of breaking strength is ≤4.0%, the CV value of elongation at break is ≤8.0%, the CV value of coefficient of variation of coiling shrinkage is ≤8.0%.

摘要:
The present invention relates to organic coloring agents with a high color stability to weathering for thermoplastics. The invention furthermore relates to a polymer composition containing at least one thermoplastic and at least one organic coloring agent, preferably a combination of at least two organic coloring agents, of a specific structure. The invention moreover relates to the use of the coloring agents according to the invention for coloring polymer compositions, in particular for transparent formulations such as are required for the production of panes for use in buildings, motor vehicles and track vehicles or aircraft.
摘要:
The present invention has an object to provide an ink for inkjet textile printing which has excellent fastnesses and causes less bleeding on a textile and to provide a low cost method for inkjet textile printing by using said ink; and relates to an ink for inkjet textile printing wherein the ink contains at least one kind disperse dye, a dispersing agent, water and at least one kind (referred to as A compound) of the compounds represented by the following formula (1): (wherein, n is an integer number of 1 to 12) and at least one kind compound (referred to as B′ compound) selected from the group consisting of alkanediols having 3 to 5 carbon atoms and polypropylene glycols, as organic solvents, the total content of A compound and B′ compound is 12 to 50% by weight based on the total amount of the ink, and the ratio by weight of A compound to B′ compound is in the range of 5:1 to 0.7:1.
