Abstract

The invention discloses a hydrophilic small-layer-difference smoothing agent for cheese and a preparation method of the hydrophilic small-layer-difference smoothing agent. The hydrophilic small-layer-difference smoothing agent for the cheese comprises, by weight, 8%-28% of oxidized Fischer-Tropsch wax, 2%-7t% of low-melting-point wax, 2%-7% of artificially-synthesized wax, 0.5%-3% of a softener, 4%-16% of an emulsifier, 0.1%-1% of sodium hydroxide or potassium hydroxide, 0.1%-4% of a cation regulator and 50%-80% of water. The smoothing agent is used for finishing the cheese, the smoothness ofyarn can be remarkably improved, the dynamic friction coefficient of the yarn can be reduced, the sewing performance and hydrophilicity of knitted fabric can be improved, yellowing can be reduced, andmeanwhile compared with a common smoothing agent, the difference between the inner layer and the outer layer of the cheese can be effectively reduced.

Description

technical field [0001] The invention relates to an auxiliary agent for cheese, in particular to a hydrophilic small layer smoothing agent for cheese and a preparation method thereof. Background technique [0002] After the package yarn has been scouring, bleaching, dyeing, etc., in the process of winding and subsequent weaving, because there is a lot of friction between the yarn and the yarn guide, heddle eye, reed and other parts, under the action of tension, The yarn is easily broken, which affects the production efficiency and processing quality, so the yarn needs to be smoothed before the bobbin is wound. [0003] In the field of package yarn processing, on the one hand, with the increasing demand for high-end yarn-dyed fabrics, the market demand for high-count yarns is also increasing. The smoothness of the smoothing agent (reducing the friction coefficient), maintaining the water absorption of the yarn, and the performance of strong protection have put forward high re...
