Abstract
The invention discloses a preparation method of a soft additive for a woolen sweater. The method comprises the following steps: 1) adding 600 parts by weight of deionized water into a reaction kettle; 2) adding 1 to 2 parts by weight of hydroxypropyl methyl cellulose, 15 to 20 parts by weight of dodecyl dimethyl benzyl ammonium bromide and 12 to 15 parts of fatty alcohol-polyoxyethylene ether, stirring uniformly, heating to 45 DEG C and preserving heat for 25 minutes, and heating to 65 DEG C and preserving heat for 1 hour; 3) cooling to 55 DEG C, adding 180 to 190 parts by weight of octamethylcyclotetrasiloxane and 12 to 15 parts by weight of N-beta-(amino ethyl)-Y-aminopropyl methyldimethoxysilane, stirring uniformly and preserving heat for 65 minutes; 4) heating to 65 DEG C, adding 2 to 3 parts by weight of potassium hydroxide, preserving heat for 40 minutes, heating to 70 DEG C, preserving heat for 3 hours and cooling to 55 DEG C; 5) adding acrylic acid, adjusting the pH value to be 4.8, supplementing deionized water until the total parts by weight is 800 parts by weight, cooling and discharging. The soft additive prepared by the method has good softening property and high stability, and is acid-resistant, alkali-resistant, non-layered and environment-friendly.
Description
Technical field
The present invention relates to the preparation method of soft additive for woollen sweater.
Background technology
Soft additive be a kind of be applicable to the multiple fibers such as cotton, wool, fiber crops, terylene, nylon and hair less, slub dyeing after softening.At present, each enterprise is used soft additive manufacturing technique complicated, and manufacturing cost is high, easily occurs poor stability, not acidproof, not alkaline-resisting, easy layering, directly has influence on the result of use of soft additive; In soft additive, contain the chemical compositions such as formaldehyde, heavy metal, environmental pollution is large.
Summary of the invention
The object of the present invention is to provide the preparation method of soft additive for a kind of woollen sweater, its soft additive softness of preparing is good, good stability, acidproof, alkaline-resisting, not stratified, environmental protection.
For achieving the above object, technical scheme of the present invention is the preparation method of soft additive for a kind of woollen sweater of design, comprises the steps:
1) 600 parts by mass deionized waters are added in reactor;
2) add 1-2 parts by mass hydroxypropyl methylcellulose, 15-20 parts by mass dodecyl dimethyl benzyl ammonium bromide, 12-15 parts by mass fatty alcohol-polyoxyethylene ether simultaneously, stir, be warming up to 45 ℃, be incubated 25 minutes, be warming up to 65 ℃, be incubated 1 hour;
3) be cooled to 55 ℃, add 180-190 parts by mass octamethylcy-clotetrasiloxane, 12-15 parts by mass N-β-(aminoethyl)-Y-aminopropyl methyl dimethoxysilane, stir, be incubated 65 minutes;
4) be warming up to 65 ℃, add 2-3 parts by mass potassium hydroxide, be incubated 40 minutes, be warming up to 70 ℃, be incubated 3 hours, be cooled to 55 ℃;
5) add propylene acid for adjusting pH value to 4.8, supplying deionized water to gross mass umber is 800 parts by mass, cooling, discharging.
Advantage of the present invention and beneficial effect are: the preparation method of a kind of woollen sweater with soft additive is provided, and its soft additive softness of preparing is good, good stability, acidproof, alkaline-resisting, not stratified, environmental protection.
