experiment example 1

[0047] First, in-situ suspension polymerization was used to prepare PS-montmorillonite particles containing different proportions of bentonite. It has the following properties:

[0048] (l) It has the ability to adsorb certain cations and anions and maintain them in an exchanged state.

[0049] (2) The action of clay minerals and water can produce swelling, dispersion and cohesion, viscosity, thixotropy and plasticity.

[0050] (3) Clay minerals can react with organic matter to form organic complexes.

[0051] As mentioned above, dyeing auxiliaries can improve performance and expand the range of applications.

[0052] Such as figure 2 As shown in (a) and (b), the organically modified montmorillonite is uniformly dispersed in the polymer, which means that the organic modification of the montmorillonite can improve the compatibility of the montmorillonite and the spinning matrix.

experiment example 2

[0054] In the experimental examples, the dyeing conditions of chemical fibers before and after using the dyeing auxiliaries of the present application are compared. Such as image 3 (a) and (b) ( image 3 (a) is the fiber dyeing effect without adding dyeing auxiliaries, image 3 (b) is the dyeing effect of adding 3% of the dyeing auxiliaries), using the dyeing auxiliaries of the present application can greatly improve the dye uptake and color fastness of the dye. In this experimental example, the suggested addition amount is 2-5%.

[0055] Compared with the prior art, the present application can obtain the following technical effects:

[0056] 1) The specific surface area of ​​the dyeing auxiliaries of this application can reach 180m 2 / g, has very good activity and can improve the combination degree of dyeing auxiliaries and dyes.

[0057] 2) The dyeing auxiliaries of the present application can effectively improve dye uptake and color fastness.

[0058] 3) The dyeing a...

Abstract

The invention discloses a dyeing auxiliary and a preparing process thereof.The dyeing auxiliary is composed of montmorillonoid in essence and organically modified through a macromolecular active monomer.Dye-uptake and color fastness of dye can be improved by the dye auxiliary, dispersity of dye in a dye solution system is improved, and precipitation of dye caused by static charge accumulation can be prevented.In addition, the dyeing auxiliary can reduce dyeing cost and increase the dye use ratio and then reduce the content of organic dye in dyeing wastewater.Therefore, the dyeing auxiliary has an important effect of environment protection.

Description

technical field [0001] The application belongs to the technical field of dyeing auxiliaries, and in particular relates to a dyeing auxiliaries with higher dye uptake and a preparation process thereof. Background technique [0002] Dyeing is a key step in the manufacture of textiles, which can enhance the appearance of textiles and give them colorful effects. Dyeing auxiliaries have received widespread attention because they can improve the dyeing effect and ensure the dyeing quality. [0003] Generally speaking, the existing dyeing auxiliaries are composed of organic matter or active rare earth elements and organic matter complexed. However, the combination ability of the current dyeing auxiliaries and the dyeing agent is not satisfactory, and it is easy to cause discoloration in the subsequent process or during the user's operation. Contents of the invention [0004] In view of this, the present application aims to solve the problem that existing dyeing auxiliaries and ...
