Description

Wash/sorona intertexture DISPERSE DYES one-bath dyeing method

Technical field

The present invention relates to a kind of washing/sorona intertexture DISPERSE DYES one-bath dyeing method ,Belong to technical field of textile printing.

Background technology

Sorona is a kind of function of the up-to-date release of du pont company and the fiber of environmental protection perfect adaptation, and it is to utilize biochemical process synthetic, 37% raw material is arranged from natural reproducible resource; Sorona with wash the lining that forms of interweaving soft hand feeling very, lasting conformality, gay colours, good COLOR FASTNESS, good moisture absorbing and sweat releasing performance, comfortable tensile elasticity and recovery characteristic and resistant and wrinkle resistance arranged, therefore, be subjected to consumer's favor deeply, good market prospects.Wash/the sorona intertexture is because polyester fiber, Sorona there are differences on physical property and chemical constitution, and cause the difference of dyeability, thereby washed/existed the problem of " homochromatism " in the dyeing of sorona intertexture.

Summary of the invention

The objective of the invention is to overcome above-mentioned deficiency, good the washing of a kind of homochromatism/sorona intertexture DISPERSE DYES one-bath dyeing method is provided, successfully realized washing/sorona intertexture low temperature one-bath process.

The object of the present invention is achieved like this: a kind of washing/sorona intertexture DISPERSE DYES one-bath dyeing method, described method comprises following technical process: will wash/the sorona intertexture places that bath raio is the water of 1: 10～1:20 under the normal temperature, add in dispersing agent NNO 0.5～1.0 g/L and the self-control carrier 1.5～2.0g/L solution, circular flow 10～15min, add DISPERSE DYES then, require to carry out the dye ligand ratio according to different color and lusters, with the vinegar acid for adjusting pH value is 5.0～6.0 o'clock, circular flow 5～10min, be warming up to 105～110 ℃ with 1.5～2 ℃/min then, temperature retention time 50～60min, the dyeing after washing, clean with reduction cleaning liquid, handle 20～25min at 60～70 ℃;

Described self-control carrier: the mixed that Ergol, alkyl benzene calcium sulfonate and castor oil are pressed mass ratio 34:2:3, leave standstill after Celsius temperature 20～35 degree stir 1.0～1.5h with magnetic stirring apparatus and can obtain lurid dyeing carrier.

Reduction cleaning liquid comprises soda ash and the 1.0～1.5g/L sodium hydrosulfite of 1.0～1.5g/L.

Dye dosage is more than or equal to 2～6% owf.

Preferred version is: will wash/to place bath raio under the normal temperature be 1: 10 water to the sorona intertexture, add in dispersing agent NNO 0.5g/L and the self-control carrier 1.5 g/L solution, circular flow 10min, add DISPERSE DYES then, require to carry out the dye ligand ratio according to different color and lusters, regulating the pH value with glacial acetic acid is 5.5 o'clock, circular flow 5min, be warming up to 110 ℃ with 2 ℃/min then, temperature retention time 50min.The dyeing after washing cleans with reduction cleaning liquid (soda ash and 1.5g/L sodium hydrosulfite by 1.5g/L are formed), handles 20min at 70 ℃.

The self-control carrier: the mixed that Ergol, alkyl benzene calcium sulfonate and castor oil press mass ratio 34:2:3, leave standstill behind the stirring 1.5h under Celsius temperature 35 is spent with magnetic stirring apparatus and can obtain lurid dyeing carrier.

The self-control carrier is a kind of compound of lipoid substance, according to the similar principle that mixes, it has plasticising, expanded effect to terylene and sorona fiber, helping DISPERSE DYES spreads to fibrous inside under lower temperature, thereby make to wash/dyeing temperature of sorona intertexture reduces to 110 ℃ by 130 ℃, homochromatism the best of sorona and terylene one-bath process under this temperature.

The invention has the beneficial effects as follows:

1, low temperature DISPERSE DYES dyes in one bath to wash/the optimum dyeing technology of sorona intertexture is: the pH value is 5.5, and the consumption of carrier is 1.5g/L, 110 ℃ of dyeing temperatures, temperature retention time is 50min.

2, employing is washed/sorona intertexture dip-dye one-bath dyeing technology, product color light stabilizing, good, the every COLOR FASTNESS height of homochromatism, and the cloth cover effect is good, the quality of finished height.

3, this technology can reduce dyeing temperature (reducing to 110 ℃ by 130 ℃) greatly, reduces production costs, and increases economic efficiency.

In sum, this colouring method can obtain color light stabilizing, the high product of good, the every COLOR FASTNESS of homochromatism, and technology is simple and direct, and the time is short, and production cost is low.

The specific embodiment

The present invention relates to wash/sorona intertexture DISPERSE DYES one-bath dyeing method, described method comprises following processing step:

To wash/to place bath raio under the normal temperature be 1: 10 water to the sorona intertexture, add in dispersing agent NNO 0.5 g/l and the self-control carrier solution, circular flow 10min, add DISPERSE DYES then, require to carry out the dye ligand ratio according to different color and lusters, regulating the pH value with HAC is 5.5 o'clock, circular flow 5min, be warming up to 110 ℃ with 2 ℃/min then, temperature retention time 50min.The dyeing after washing cleans with reduction cleaning liquid (soda ash and 1.5g/L sodium hydrosulfite by 1.5g/L are formed), handles 20min at 70 ℃.

The present invention has taked to add the method for self-control carrier in dye liquor, the above-mentioned dyeing of taking, just the consumption of self-control carrier is respectively 0.5g/l, 1.0g/l, 1.5g/l, 2.0g/l, 2.5g/l in dye liquor, dye wash/its color feature value of Sorona intertexture is shown in following table 1-1

Table 1-1 carrier consumption to wash/the sorona intertexture in the influence of two component Δ E

The carrier consumption/(g/L)	Wash the K/S value	Sorona K/S value	Wash Sorona value of chromatism Δ E
				0.5	4.35	6.83	3.34
1.0	5.97	6.99	2.89
				1.5	7.05	7.13	1.37
2.0	6.77	6.89	2.01
				2.5	5.73	6.78	2.54

By table 1 result of the test as can be seen, along with carrier concn increases, the K/S value of terylene and Sorona also constantly increases, but after being increased to a certain degree, the K/S value of terylene and Sorona no longer increases with carrier concn, reduces on the contrary.This is because the self-control carrier can play plasticization to terylene and Sorona fiber, dyes process in the quickening, improve the K/S value, and the concentration of carrier is high more, and this effect is strong more.Desirable carrier concn should be just to reach capacity and unlikely formation third phase in dye bath.After forming third phase, can increase the dissolving of dyestuff in water, more dyestuff is remained in the dye bath, reduce the distribution coefficient of dyestuff in fiber and solution, thereby reduce the dye-uptake of dyestuff, the K/S value of terylene and Sorona is reduced; In addition, carrier has the cause to the dyestuff desorption when high temperature; The consumption of self-control carrier is during with 1.5g/L, and the aberration of terylene and Sorona satisfies the requirement of homochromatism less than 2.Therefore, the optimum amount of self-control carrier is 1.5g/L.

Table 1-2 washs/every dyefastness of sorona intertexture

Figure 2013101381379100002DEST_PATH_IMAGE002

By showing 1-1 and table 1-2 test result as can be seen, low temperature DISPERSE DYES dyes in one bath washs/and the homochromatism of sorona intertexture is good, and light fastness is fine, soaping fastness and rub the sassafras fastness also more than 4 grades, perspiration fastness also is more than 4 grades basically, and every generally dyefastness is all good.
