Technical Field

The invention relates to the field of preparation of finishing agents, in particular to a preparation method of a finishing agent for fabric softening finishing.

Background

The application of the softening agent to the textile has been for a half a century, and along with the higher and higher requirements of people on the quality of the textile, the softening agent is required to be novel in material, comfortable to wear, soft in hand feeling and elegant in appearance, so that the softening agent is also paid more and more attention.

The organic silicon softener has the outstanding advantages of excellent smoothness, flexibility, film forming property and the like, and is widely used in various textile after-finishing, wherein the amino modified organic silicon softener has the best hand feeling. But the application of the fabric is limited due to the defects of hydrophobicity, stuffy feeling of the fabric finished by the fabric, high-temperature yellowing and the like.

In the prior art, amino groups of amino silicone oil are mainly chemically modified, including reaction with epoxy compounds (also called epoxidation) and reaction with acylating agents (acylation), but in the epoxidation reaction, active hydrogen of primary amino groups and secondary amino groups can react with epoxy groups, i.e. nonselective reaction is carried out, so that viscous products are obtained and emulsification is difficult to carry out.

Meanwhile, since the epoxy group is easily subjected to ring opening in an aqueous solution, the reaction cannot be performed in an aqueous solution but only in a solvent. In the actual production, the addition of the solvent not only increases the production cost, but also brings about the hidden danger of explosion in the production because the added solvent is difficult to be completely recovered. Therefore, a new synthetic route is sought according to actual production conditions, and the preparation of polyether amino modified polyorganosiloxane with no or little addition of organic solvent is a new subject of attention and research in actual production.

Disclosure of Invention

In order to solve the problems, the invention provides a preparation method of a finishing agent for fabric softening finishing, polyether groups are successfully introduced into amino silicone oil, the stability of the traditional amino silicone oil emulsion is improved, the using amount of an emulsifier is reduced under the condition of not using a solvent, and meanwhile, in the synthesis and emulsification processes of the softening agent, environment-friendly raw materials and the emulsifier which are easy to biodegrade, have treatability, low toxicity and do not contain environmental hormones are selected according to new environmental evaluation standards to replace the existing products.

In order to achieve the purpose, the invention adopts the technical scheme that:

a preparation method of a finishing agent for fabric softening finishing comprises the following steps:
