Abstract

The invention discloses a preparation method for a swelling agent for a woolen sweater. The preparation method comprises the following steps: 1) adding 300-350 mass parts of water into a reaction kettle, heating to 60 DEG C, and mixing uniformly; 2) at the same time, adding 100-110 mass parts of sulfonated tallow sodium dioctyl, 1-2 mass parts of ethyltrimethoxysilane, and 200-210 mass parts of fatty alcohol ethoxylates, mixing uniformly, performing thermal reaction for 65 min, heating to 85 DEG C, and keeping the temperature for 1 hour; 3) adding 1-2 mass part of polyoxyethylene esters of oleic acid, 60-65 mass parts of sodium chloride, and 25-30 mass parts of urea, mixing uniformly, and performing thermal reaction for 55 min; 4) adding isopropanolamine to adjust the pH value to 4.5, mixing uniformly, cooling, and discharging. The swelling agent prepared by the invention can be added during washing wool before removing scales, can effectively improve the bulkiness of the woolen fabric, and can effectively prevent dyeing of woolen sweater product, and dyeing defect, color light, and local unevenness after printing.

Description

The preparation method of leavening agent for woollen sweater

Technical field

The present invention relates to the preparation method of leavening agent for woollen sweater.

Background technology

Leavening agent is a kind of at woollen sweater one of indispensable additive on the make, and the quality of leavening agent directly has influence on the quality of Color in woollen sweater subsequent production process.At present, leavening agent washing force and penetrability effect that each enterprise is used are all poor, and fabric color, mellowness after processing are undesirable.And in leavening agent, containing 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 leavening agent for a kind of woollen sweater, its leavening agent of preparing adds while cleaning before for wool stripping squama, can effectively improve the bulking intensity of wool fabric, can effectively prevent that the look after woollen sweater garment dyeing, stamp is colored, look shallow and local inhomogeneous.

For achieving the above object, technical scheme of the present invention is the preparation method of leavening agent for a kind of woollen sweater of design, comprises the steps:

1) in reactor, add 300-350 parts by mass water, be heated to 60 ℃, stir;

2) add 100-110 parts by mass sulfosuccinate dibutyl ester sodium salt, 1-2 parts by mass ethyl trimethoxy silane, 200-210 parts by mass fatty alcohol-polyoxyethylene ether simultaneously, stir, insulation reaction 65 minutes, is heated to 85 ℃, is incubated 1 hour;

3) add 1-2 parts by mass polyoxyethylene oleic acid ester, 60-65 parts by mass sodium chloride, 25-30 parts by mass urea, stir, insulation reaction 55 minutes;

4) add isopropanolamine to regulate pH value to 4.5, stir, cooling, discharging.

Advantage of the present invention and beneficial effect are: the preparation method of a kind of woollen sweater with leavening agent is provided, its leavening agent of preparing adds while cleaning before for wool stripping squama, can effectively improve the bulking intensity of wool fabric, can effectively prevent that the look after woollen sweater garment dyeing, stamp is colored, look shallow and local inhomogeneous.
