Technical Field
The invention relates to the field of textile dyeing and finishing, and particularly relates to a low-foam penetrant, and a preparation method and an application method thereof.
Background
Penetrants are known by their name to act as penetrants, which are surfactants in the textile industry that allow liquids to penetrate rapidly and uniformly into the fibers, promoting rapid wetting of the fiber or fabric surface by water, and penetration into the fiber or fabric. The penetrant is applied to dyeing and finishing processes and has wide application. The pretreatment of cotton textiles is mostly wet processing, and a penetrant is an essential assistant for enabling a treatment solution to be uniformly and rapidly distributed or act on the inside of the textile.
The penetrant applied to the printing and dyeing process at present is mainly compounded by various surfactants, the surfactants, water and other additives are prepared into working liquid when the penetrant is used, in order to make the working liquid uniform, intensive stirring is carried out in the preparation process, however, in the stirring process, air is involved into the working liquid along with stirring, and in addition, air is also brought when the fabric enters a working liquid mangle, and some processes inevitably generate gas. In this in-process, produce a large amount of foams, can cause the operator to see the actual liquid level of unclear treatment fluid to lead to the working solution to spill over, it is inhomogeneous to change the material, remains a large amount of foams during final blowing, and the blowing is not clean. Excessive foam can float the fabric, block a spray head for circulating the working solution, aggravate the accumulation of dirt of the working solution and prevent the dirt from being stained on the surface of fabrics or equipment, and aggravate the foaming of the surfactant and cause more serious foaming sometimes after hydrogen peroxide and caustic soda are added into the working solution.
In order to ensure the rinsing effect, a large amount of water is needed for cleaning for many times, water resources are wasted in transition, and meanwhile, a large amount of alkaline waste liquid is generated to pollute the environment. In the actual printing and dyeing operation, the phenomena of too much foam, vehicle winding, cylinder blockage or no cloth walking are often caused, the problem can be solved only by adding a defoaming agent, most of the defoaming agents are silicone defoaming agents, the defoaming agent is not resistant to high temperature, high alkali and high shear, and meanwhile, if the water quality is hard, Ca (calcium) is hard2+、Mg2+、Fe3+When the defoaming agent is demulsified, the result is that floating oil is generated, which is floated in the dye liquor and combined with scum and dirt generated by metal ions or fibers, auxiliaries and impurities in dye to generate irregular color spots, color blocks and oil stains to be adhered to the fabric and the inner wall of equipment.

Detailed Description
All raw materials used in the present invention are conventionally used and commercially available. In the present invention, all amounts, percentages and parts are by weight, unless otherwise specified.
Example 1
The embodiment of the invention provides a low-foam penetrant, which comprises the following components in percentage by mass:
the main components of the isomeric decyl alcohol polyoxyethylene ether are isomeric decyl alcohol and ethylene oxide, and the chemical structure of the isomeric decyl alcohol polyoxyethylene ether is iso-C10H21O-(CH2CH2O) -H, the isomeric fatty dodecyl alcohol polyoxyethylene ether belongs to isomeric alcohol ether, is a high-efficiency dispersing agent, wetting agent and emulsifying agent, does not contain benzene ring structure, and is an excellent substitute of alkylphenol polyoxyethylene ether in textile auxiliaries and detergents.
The block polyether is preferably an EO/PO block polyether in the embodiment, the EO/PO block polyether is composed of polyoxyethylene (EO) and Polyoxypropylene (PO), is generally formed by randomly copolymerizing EO and PO, and has good low-foaming performance, so that the penetrant prepared from the EO/PO block polyether has good low-foaming performance, the technical problem that foam is generated in the penetration process to influence the preparation process is effectively solved, and a large amount of foam is prevented from remaining in the discharging process to block a spray head.
The working solution for the pretreatment of cotton textiles is mostly carried out in strong alkali bath, which requires that the used penetrating agent can still keep good wetting permeability in the strong alkali bath, and can still keep high-efficiency permeability even if the working solution can resist 200g/L of strong alkali, the ordinary penetrating agent JFC can not meet the requirement, and an additional strong alkali-resistant penetrating agent must be searched, and the phosphate ester has better permeability and alkali resistance and can be used as the strong alkali-resistant penetrating agent exactly, and meanwhile, when the monoester content in the synthesized phosphate ester product is higher, the alkali-resistant permeability of the product is the best.
The tributyl phosphate is mainly used as a solvent, and is also commonly used as a plasticizer of nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, an extractant of rare metals and the like, and a heat exchange medium.
