Abstract
The invention discloses a dyeing method of polyester or acrylic fibers. In parts by weight, a dye bath formed by 1 part of leveling agent, 0.075 part of dye and 0.225 part of acetic acid is heated until the temperature thereof reaches 85 DEG C and then is used for dyeing 10 parts of acrylic fibers or 9 parts of polyester fibers, so as to obtain level-dyed color. The dyeing method of polyester or acrylic fibers has the beneficial effects that level-dyed fabrics of polyester or acrylic fibers with excellent color fastness can be obtained through tests by use of reasonable matching of the leveling agent, the dye and the acetic acid in combination with a higher dyeing temperature at 85 DEG C, the process of the dyeing method is simple, and the dyeing property can be effectively improved without adding extra operation. Especially, the leveling agent, which is prepared from raw materials such as ethoxylated lanolin, triethanolamine, N-phenyl-2-naphthylamine, benzyl chloride, octadecyl isothiocyanate, N,N-dimethylethanolamine and methylbenzene through steps of mixing and dissolving, is capable of further improving the color fastness.
Description
Technical field
The present invention relates to a kind of colouring method, the colouring method of especially a kind of terylene or acrylic fiber.
Background technology
Textile auxiliary is most important to the surcharge of raising textiles, not only can make functions of textile fabrics, and can make that it is superior, have more sense of the times, but the dyeing that the prerequisite with these advantages is fabrics wants even, very effective method is that to delay the auxiliary agent dying or move the effect of dying be that levelling agent reaches even dyeing effect with having.
Levelling agent great majority are water miscible surfactants, impact according to levelling agent on dye diffusion and concentration class, mainly be divided into two types: one is close fibroid levelling agent, it does not almost affect the concentration class of dyestuff. but the affinity of fiber is greater than to the affinity of dyestuff to fiber, therefore in dyeing course, this type of levelling agent can be first combined with fiber, reduce dyestuff dyeing rate, but with the variation of dyeing condition, dyestuff can replace levelling agent gradually, anchor on fiber, this class levelling agent only has slow effect of dying; It is two for close dyestuff levelling agent. and it can significantly improve dyestuff concentration class, the affinity of dyestuff is greater than to the affinity of dyestuff to fiber, before dying on dyestuff. levelling agent is first combined with dyestuff and is generated certain stable aggregation, thereby has reduced the diffusion rate of dyestuff and delayed dyeing time.Along with the change of condition, dyestuff departs from levelling agent gradually, be combined with fiber, but now levelling agent still has certain affinity to dyestuff, fabric for not level dyeing can also be left behind dyestuff from fiber, on dye the place of lighter color, therefore this class levelling agent not only has and slowly dyes effect, and has the effect of dying that moves.
Summary of the invention
A kind of terylene that the object of the invention is the deficiency in order to solve above-mentioned technology and design or the colouring method of acrylic fiber, adopt terylene or the acrylic fibers uniform dyed fabric that can obtain in this way good COLOR FASTNESS.
A kind of terylene that the present invention is designed or the colouring method of acrylic fiber, with the dye bath of 1 part of levelling agent, 0.075 part of dyestuff, 0.225 part of acetic acid, be heated to 85 DEG C, dyes 10 parts of acrylic fibers or 9 parts of polyster fibres, obtains level dyeing color, is more than all weight portion.
As preferably: described levelling agent makes as follows: by 230-240 part N, N-dimethylethanolamine, 2 parts of N-phenyl-2-naphthylamines, 2-3 part triethanolamine, 1-2 part triphenylmethane triisocyanate and 50 parts of ethoxylation lanolin dissolve with 1000 parts of toluene, 800 parts of octadecylisocyanates are dissolved with 2000 parts of toluene, two kinds of mixed liquors are mixed, and react 6h at 75 DEG C; Then with 800 parts of dilution with toluene reactant mixtures and add 300-350 part Lvization Benzyl to stir and evenly mix and obtain levelling agent; The above-mentioned parts by mass that is all.
A kind of terylene that the present invention is designed or the colouring method of acrylic fiber, its beneficial effect is: by the rational proportion of levelling agent, dyestuff and acetic acid, be aided with 85 DEG C of higher dyeing temperatures, through test, can obtain
The terylene of good COLOR FASTNESS, acrylic fibers uniform dyed fabric, this colouring method technique is simple, on the basis that does not increase operation bidirectional, can effectively improve dyeability.Especially with ethoxylation lanolin, triethanolamine, N-phenyl-2-naphthylamine, Lvization Benzyl, octadecylisocyanate, N, N-dimethylethanolamine, toluene etc. are raw material, modulate the levelling agent forming through operations such as mixed dissolutions, can further improve COLOR FASTNESS.
