Abstract

The invention discloses a preparation method of an alkali-resistant penetrating agent for mercerizing. The method is characterized by firstly using n-tetradecanol and ethylene oxide as raw materials,then adding n-caprylic alcohol and glucosum anhydricum, using crude glycosides, which is not completely dealcoholized after synthesis of alkyl glycoside, as a raw material, using remained fatty alcohol as a solvent, adding phosphorus pentoxide to obtain a wetting and penetrating main accessory ingredient with the characteristics of high wetting power, better alkali resistance, better temperature resistance, and the like; using an inorganic acid byproduct produced through an active agent for preparing block type silicone oil, and adding the block type silicone oil to the alkali-resistant penetrating agent, so that the yellowing of a mercerized fabric is reduced, and the softness and the fineness are improved; forming an anti-microbial protection film through chitosan surface film-forming; finally, adding a composite biological enzyme preparation so as to damage and remove a primary cell wall on an outer layer of cellulose, so that pectic substances between the primary cell wall and a secondary cell wall are exposed, hydrophobic impurities such as the pectic substances and waxes on fabric are removed, the penetrating agent adsorbed on the surface of the fabric is reduced, so as to becleanly removed during water washing, and the fabric is level and uniform.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing auxiliaries, and in particular relates to a preparation method of a mercerizing alkali-resistant penetrant. Background technique [0002] The mercerizing process is to make the cotton fiber produce a silk-like durable luster, improve the dimensional stability of the finished product, and also improve the ability to absorb dyes, and give the fabric a soft and plump feel. In the mercerizing process, caustic soda with a high concentration is used. In the continuous mercerizing process, the time for cotton fabrics in the lye solution is generally only 30~50s, so the permeability of the mercerizing solution is very important. In this concentration of lye, the general penetrating agent cannot be used, and the penetrating agent specially used for the mercerizing process must be used. Therefore, the mercerizing penetrating agent is often used as a special auxiliary agent. In the concentrated ...
