Embodiment Construction

[0020] The present invention will be further described below in conjunction with embodiment.

[0021] A method for deepening and finishing wool fabrics, said method at least comprising the following steps:

[0022] (1) Preparation of fluoroalkyl modified amino silicone oil:

[0023] Add 3L of toluene to the reaction vessel, and then add 3KG N-β-aminoethyl-γ-aminopropyl methyl silicone oil and 3.2KG hexafluorobutyl acrylate under the protection of nitrogen; heat up to 65°C, keep the temperature for 3h, remove Solvent, obtains fluoroalkyl modified amino silicone oil, the massfraction of fluorine is 25%;

[0024] (2) Emulsification of fluoroalkyl modified amino silicone oil:

[0025] Add 1KG fluoroalkyl modified amino silicone oil to the high-speed shear dispersing emulsifier, then add 0.15KG fatty alcohol polyoxyethylene ether surfactant, stir and emulsify at room temperature at 2800 r / min for 15 minutes, and dilute with water to obtain the mass concentration 30 g / L finishing...

Abstract

The invention provides a method for darkening finishing of a wool fabric, and the method at least comprises the following steps: (1) preparation of fluoroalkyl modified amino silicone oil; (2) emulsifying of the fluoroalkyl modified amino silicone oil; (3) padding; (4) preliminary drying; and (5) baking. Compared with the prior art, the method for darkening finishing uses the fluoroalkyl modified amino silicone oil as a finishing agent, the apparent color depth (K / S) of the wool fabric after the finishing can be increased by more than 20%, and the hand feeling, the flexibility and the serviceability of the fabric may not be affected.

Description

technical field [0001] The invention relates to a method for finishing fabrics, in particular to a method for deepening and finishing wool fabrics. Background technique [0002] Fabric dyeing depth is restricted by fiber dyeing balance and dyeing fastness, and sometimes it is difficult to meet the requirements. For dark-colored products whose dyeing depth does not meet the requirements or the amount of dye is large, the darkening agent has good practical value. One of the deepening methods is to cover the surface of the fabric with a low refractive index film to change the degree of reflection and refraction of the fiber to light, so as to obtain a better apparent dark color effect. More film-forming substances are organic fluorine, Silicone and acrylate resins. Organic fluorine resin has a good dark color effect due to its low refractive index (below 1.40), but its price is high; silicone resin has good flexibility but poor darkening effect; acrylic resin has good dar...
