Problems solved by technology

[0006] The technical problem to be solved in the present invention is to overcome the easy foaming of the penetrating agent for mercerizing in the prior art, and the existence of the foam brings a lot of inconvenience to the technological processes such as mercerizing, and it is difficult to recycle the lye after mercerizing, which not only increases the production cost, It also causes pressure on the environment; and the phosphate ester penetrant contains phosphate components. If the product is used in large quantities, it will cause the defect of eutrophication in the water body. A kind of mercerizing penetrant and its preparation method are provided

[0069] Table 1

[0070]

[0071] The proportioning ratio of each raw material component of the penetrant in this embodiment is shown in Table 1. Wherein, the alkyl diphenyl ether sulfonate is sodium octyl diphenyl ether sulfonate; the fatty alcohol polyoxyethylene sulfate is isomerized decanol polyoxyethylene ether sulfate (EO number is 3);

[0072] Preparation of silicon-modified polyether:

[0073] (1) Preparation of polyether: In a pressure reactor, add 100 parts of isomeric tridecanol (EXXAL TM 13) and KOCH 3 (The amount is 0.2% of the weight of isomeric tridecyl alcohol), replace the air in the kettle with nitrogen for 3 times, heat up to 110° C., and dehydrate for 30 minutes under a vacuum environment below −0.09 MPa. Then the temperature was raised to 120°C, and ethylene oxide was slowly added dropwise (the molar ratio of ethylene oxide to isotridecyl alcohol was 9:1), and the ring-opening polymerization was carried out at a pressure of 0.2 MPa and a temperature o...

[0086] The proportioning ratio of each raw material component of the penetrant in this embodiment is shown in Table 1. Wherein, alkyl diphenyl ether sulfonate is sodium dodecyl diphenyl ether sulfonate; fatty alcohol polyoxyethylene sulfate is isomeric tridecyl alcohol polyoxyethylene ether sulfate (EO number is 4);

[0087] Preparation of silicon-modified polyether:

[0088] (1) Preparation of polyether: In a pressure reactor, add 100 parts of isooctyl alcohol (6-methyl-1-heptanol) and KOH (the amount is 0.2% of the weight of isooctyl alcohol), and replace the kettle with nitrogen Inner air 3 times, heat up to 110°C, and dehydrate for 30min in a vacuum environment below -0.09MPa. Then the temperature was raised to 120°C, and ethylene oxide was slowly added dropwise (the molar ratio of ethylene oxide to isooctyl alcohol was 3:1), and the ring-opening polymerization was carried out at a pressure of 0.25 MPa and a temperature of 130°C. After the ethylene oxide is finished, the...

Embodiment 3

[0100] The proportioning ratio of each raw material component of the penetrant in this embodiment is shown in Table 1. Among them, alkyl diphenyl ether sulfonate is sodium decyl diphenyl ether sulfonate; fatty alcohol polyoxyethylene sulfate is C 12-14 Alcohol polyoxyethylene ether sulfate (EO number is 3);

[0101] Preparation of silicon-modified polyether:

[0102] (1) Preparation of polyether: In a pressure reactor, add 100 parts of isomeric tridecanol (EXXAL TM 13) and KOH (the amount of which is 0.3% of the weight of isomeric tridecyl alcohol), replace the air in the kettle with nitrogen for 3 times, raise the temperature to 110°C, and dehydrate for 30min under a vacuum environment below -0.09MPa. Then the temperature was raised to 120°C, and ethylene oxide was slowly added dropwise (the molar ratio of ethylene oxide to isotridecyl alcohol was 10:1), and the ring-opening polymerization was carried out at a pressure of 0.35 MPa and a temperature of 130°C. After the drop...

Abstract

The invention discloses a mercerizing penetrant and a preparation method thereof. The mercerizing penetrant comprises 20 to 30 wt% of silicon-modified polyether, 10 to 20 wt% of fatty alcohol polyoxyethylene ether sulfate and 10 to 20 wt% of alkyl diphenyl ether sulfonate, with the balance being water, wherein the silicon-modified polyether has a number-average molecular weight of 200 to 2000 g / mol and has a general structural formula as described in the specification. In the formula, R is a straight-chain or branched-chain C6-18 alkyl group; R' is a straight-chain or branched-chain C1-10 alkylene group or a C6-10 arylene group; m is in a range of 1 to 20; n is in a range of 0 to 20; and m and n are both integers. The preparation method for the mercerizing penetrant is simple to operate. Through mutual synergism of the components of the mercerizing penetrant, the prepared mercerizing penetrant has alkali resistance of 300 g / L and shows good penetration performance and alkali resistancestability in an alkali solution with a concentration of 180 to 300 g / L; and the mercerizing penetrant has low foam, does not influence the recovery of alkaline liquor and obviously improves mercerizing effect.

Description

technical field [0001] The invention relates to a mercerizing penetrant and a preparation method thereof. Background technique [0002] Mercerizing refers to the process of treating cotton products (yarns, fabrics) with concentrated caustic soda solution under tension, and then washing away caustic soda under tension; it can improve the adsorption performance, gloss and dimensional stability of fabrics , is an important link in the pre-treatment of fabric dyeing and finishing. In order to improve the quality of mercerizing products and obtain a uniform mercerizing effect, mercerizing additives, such as penetrating agents, should be added to the mercerizing liquid. In mercerizing finishing, the concentration of caustic soda is generally higher than 180g / L, and it becomes viscous at low temperature, and the mercerizing process takes a short time due to the sharp shrinkage of cotton and hemp fibers, which reduces the permeability of lye, so it can only achieve surface merceriz...
