Description
Technical Field
The invention relates to a preparation method of a fabric handfeel agent.
Background
In each processing procedure from spinning, weaving and printing to finished products, the textile industry needs to use different auxiliary chemical agents according to the performances of various fibers so as to improve the quality of textiles, improve the processing effect, improve the production efficiency, simplify the technological process, reduce the production cost and endow the textiles with various excellent application performances. Such auxiliary chemicals are commonly referred to as textile dyeing and finishing aids. As one of important textile dyeing and finishing auxiliaries of textiles, the handfeel agent can be adsorbed on the fiber surface of the textile, so that the original rough handfeel of the textile is changed, and the textile has soft, smooth and comfortable handfeel. Hand feel agents can be classified into 4 classes according to chemical composition: non-surface-active, reactive and high-molecular polymer emulsion types. The emulsion of high molecular polymer is mainly made of high molecular polymer such as polyethylene, organic silicon resin, etc., and the organic silicon hand feeling agent has the advantages of good lubricity, softness, hydrophobicity, etc., and is synthesized to be nontoxic, free from environmental pollution and reasonable in cost, so the emulsion has been rapidly developed into the hand feeling agent with wide application, good performance and most outstanding effect on textile.
Chinese patent application No. 201510294008.8 discloses an organosilicon hand feeling agent containingWherein x=8-18; y=1-5, z=1-5. The novel aminophenyl modified silicone oil prepared by the invention has the characteristics of stain resistance, quick drying property, fluff hand feeling, good stability and the like, and is more suitable for the market demands. The organosilicon hand feeling agent is generally treated on textiles in the form of emulsion of water dispersion when in use, but the traditional organosilicon hand feeling agent is basically water-insoluble oil, and an emulsifier is required to be additionally added before use, and the organosilicon hand feeling agent can be used for printing and dyeing production after emulsification. Some organic silicon handfeel agents have a certain self-emulsifying function, but have poor stability, and are easy to break and separate oil.
Disclosure of Invention
Therefore, the invention provides a preparation method of a fabric handfeel agent aiming at the defects pointed out by the background technology.
In order to achieve the above purpose, the invention is realized by the following technical scheme:
a method for preparing a fabric hand feeling agent, comprising the following steps:
(1) Firstly, adding polyether amine and polyether silicone oil into a reaction kettle, then adding an organic solvent accounting for 40-50% of the mass of the polyether amine, heating to 80-88 ℃, stirring for reaction for 6-10h, and cooling to below 40 ℃ after the reaction is finished to obtain a pale yellow reaction intermediate;
(2) Adding 3-chlorine-2-hydroxy sodium propane sulfonate into water, adding sodium hydroxide solid and organic solvent after dissolving completely, and stirring uniformly to obtain mixed solution;
(3) And (3) adding the mixed solution obtained in the step (2) into a reaction kettle filled with the reaction intermediate, heating to 80-88 ℃ and reacting for 6-10h to obtain the required fabric handfeel agent.
The further improvement is that: the organic solvent is isopropanol.
The further improvement is that: the polyether amine is formed by mixing polyether amine ED-600 and polyether amine D-2000 according to a molar ratio of 1:2.
The further improvement is that: the structural formula of the polyether silicone oil is as follows:
wherein m has a value of 100-300, R 2 Is an aliphatic polyester group comprising 5 to 10 repeating structural units Wherein n is 1 +n 2 +n 3 ＝20-40。
The further improvement is that: the mol ratio of the polyether silicone oil to the polyether amine is 1:1.4-1.8.
The further improvement is that: based on the total mass of the reaction intermediates, the mass fraction of the 3-chloro-2-hydroxy propane sodium sulfonate in the step (2) is 6-8%, the mass fraction of the sodium hydroxide is 0.8-2%, the mass fraction of the water is 32-36%, and the mass fraction of the organic solvent is 45-55%.
By adopting the technical scheme, the invention has the beneficial effects that:
the fabric handfeel agent prepared by the invention is a branched multi-component copolymerized block modified organic silicon product, a main chain of a molecular structure is regularly embedded with a plurality of organic chain segments such as polyether, polyester, organic silicon and the like, and then hydroxyl, halogen atoms and sulfonate groups are introduced into the branched chain, so that the self-emulsifying function is endowed, and meanwhile, the fabric handfeel agent has the characteristic effect of softness and silkiness, and the defect that emulsion formed by the traditional organic silicon handfeel agent is poor in stability and needs to be additionally added with an emulsifying agent is overcome. Firstly, polyether silicone oil is subjected to ring opening reaction under alkaline conditions to produce a reaction intermediate, then the ring-opened polyether silicone oil is subjected to grafting modification through chemical reaction, 3-chloro-2-hydroxy sodium propane sulfonate is grafted on a branched chain of the polyether silicone oil, and the synthetic fabric hand feeling agent is directly used without adding an emulsifying agent for emulsification operation before being used, so that the operation is simpler and more convenient.
In addition, a color fixing agent and a whitening agent are also used in the printing and dyeing process, and the traditional organic silicon handfeel agent is easy to react with the whitening agent and the color fixing agent, so that the final quality of a finished product is affected. Especially acrylic fixing agents and polyurethane fixing agents, produce small particle impurities when mixed with silicone feel agents. The fabric handfeel agent prepared by the application does not react with the color fixing agent and the whitening agent, and the finished product after processing has soft and smooth handfeel.

TABLE 1
Taking 18gsm of spun-bonded non-woven fabric, soaking the spun-bonded non-woven fabric in finishing liquid for 30 times, lifting out, drying the spun-bonded non-woven fabric at 80 ℃ after water drops are dried, and then drying at 80 ℃ to test hydrophilicity and softness. Hydrophilicity was expressed as permeation time, and the results of the tests were shown in Table 2, with the shorter permeation time, which represents the better hydrophilicity, tested by a LISTERAC nonwoven fabric electronic moisture permeation tester. Softness is expressed in terms of softness, with the softness values being smaller as measured using a Handle-O-Meter softness Meter, which represents softer and the test results are shown in Table 3.

The fabric feel of reference 4 was formulated to provide a stable emulsion by adding an emulsifier (e.g., the Lutensol XL50 emulsifier, manufactured by Basf).
