Problems solved by technology

However, it is sensitive to chemical additives such as electrolytes, pH values, and dye discharge agents, and has poor adaptability. In practical applications, secondary thickening is often required, which increases the solid content of the original paste.
On the other hand, although its thickening ability is very strong, the synthetic thickener still has a certain solid content, and its pigment printing feel cannot achieve the soft effect of dye printing

example 1

[0024] Example 1: A kind of W / O type ultra-low solid content printing emulsified paste of the present invention is made up of the raw material of following weight part:

[0025] 25 parts Decamethylcyclopentasiloxane

[0026] 3 parts sorbitan oleate (Span80)

[0027] 75 parts tap water

[0028] Prepare the above components according to the following preparation method: at room temperature, put decamethylcyclopentasiloxane in the container, add sorbitan oleate (Span80), and stir it at a slow speed with a high-power mixer to evenly disperse it in the In decamethylcyclopentasiloxane, the stirring speed is increased to 10000 rev / min, and tap water is slowly added while stirring, and the addition speed is controlled at 5 parts / min to ensure that the added tap water is at the level of decamethylcyclopentasiloxane. Rapidly emulsify and disperse in medium; after adding all the tap water, continue to stir at high speed for 5-10 minutes to obtain the printing emulsified paste of the pr...

Abstract

The invention discloses a W / O type printing emulsion paste with super-low solid content rate, comprising the following raw materials according to parts by weight: 20 to 30 parts of methylsiloxane compound, 70 to 80 parts of water, and 2.5 to 4 parts of nonionic surface active agent. The method for preparing the W / O type printing emulsion paste comprises the following steps: placing the methylsiloxane compound into a vessel as an external phase at room temperature of T being more than 0 or being less than 40 DEG C, adding the nonionic surface active agent into the vessel to lead the external phase to be evenly scattered or dissolved and evenly stirred; under high speed stirring at rotating speed of between 1,000 and 10,000 revolutions / minute, slowly adding an internal phase component of water; controlling the adding speed to ensure that the added water can quickly emulsified and scattered in the methylsiloxane compound; keeping on stirring for 5 to 10 minutes after the mixture is impasted to obtain a finished product. The paste and the method have the advantages of non environment or safety problems, good stability and solid content rate close to zero.

Description

technical field [0001] The invention belongs to the field of pigment / pigment printing emulsification paste for textiles, and in particular relates to an environmentally friendly and pollution-free W / O type ultra-low solid content printing emulsification paste suitable for pigment printing and a preparation method thereof. Background technique [0002] Pigment printing is to use some polymer compounds with high adhesion ability, appropriate mechanical and physical properties and stable chemical properties to form a film on the fabric after printing, so as to fix the pigment on the fabric. Compared with dye printing, pigment printing has the following outstanding advantages: simple printing process, clear pattern outline, convenient color matching of color paste, complete color spectrum, and good color reproducibility; strong applicability, suitable for all fibers, and sometimes dyes can also be obtained Printing effect that cannot or is difficult to obtain by printing; low ec...
