Organosilicon softening finishing agent with ice-cold feeling and preparation method of organosilicon softening finishing agent

Abstract

The invention relates to the technical field of printing and dyeing auxiliaries, particularly to an organosilicon softening finishing agent with ice-cold feeling and a preparation method of the organosilicon softening finishing agent. The organosilicon softening finishing agent consists of the following raw materials in parts by weight: 10-60 parts of hydrophilic ternary copolymerized organosilicon, 0.1-30 parts of microcapsule ice-cold particles, 0.4-2.4 parts of glacial acetic acid and 20-70 parts of water. The preparation method comprises the following steps: adding hydrophilic ternary copolymerized organosilicon into an emulsifying machine, turning on the emulsifying machine, adding glacial acetic acid, then gradually adding distilled water for emulsification, after silicone oil is changed into a uniform emulsifiable solution, gradually adding the microcapsule ice-cold particles which are 0.1-30 in parts by weight into the emulsifiable solution, and when the microcapsule ice-cold particles are fully dissolved, turning off the emulsifying machine so as to obtain the organosilicon softening finishing agent. The organosilicon softening finishing agent has excellent hydrophilicity, excellent yellowing resistance and excellent launderability, and has the ice-cold feeling that common silicone oil cannot compare.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a silicone softening agent with a cool feeling and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people's demand for silicone softeners is not limited to the soft touch, but also gradually increases the requirements for the sweat absorption and moisture permeability of clothing, and at the same time requires a cool and silky feel. This makes the development of silicone softening agents gradually develop in a diversified direction. It is necessary to keep the soft, fluffy and smooth feel of the silicone softening agent, and also require the finished fabric to have hydrophilic moisture permeability and cool surface feeling. [0003] Although the traditional amino silicone oil has excellent softness, the hydrophilicity of the fabric after finishing is poor, which makes the moisture absorption...

AI Technical Summary

Problems solved by technology

[0003] Although the traditional amino silicone oil has excellent softness, the hydrophilicity of the fabric after finishing is poor, which makes the moisture absorption and perspiration of the finished fabric poor, and it is easy to feel stuffy in summer, and amino silicone oil is due to the primary amino groups on the molecular chain. The high content is prone to "yellowing" phenomenon, which makes the fabric gradually turn yellow during the wearing process and affects the quality and appearance of the fabric

In addition, the stability of the amino silicone oil emulsion is relatively poor. Since the fabric will contain alkali agents during the dyeing process, if these alkali agents are not thoroughly washed, they will enter the finishing solution during the finishing process, making the pH of the finishing solution higher, thus It will cause demulsification of the amino silicone oil emulsion and produce "silicon spots" that are difficult to clean on the surface of the fabric, which limits the use of amino silicone oil

[0004] The commonly used hydrophilic silicone oil in the market is the product of the addition reaction of hydrogen-containing silicone oil and allyl glycidyl ether. Although the fabric is treated with this hydrophilic silicone oil, the hydrophilicity of the fabric will be improved, but due to this The silicone oil-like molecular chain does not contain strong polar groups (such as amino groups, secondary amino groups, etc.), so the fabric after finishing has poor hand feel and washability. Washing the fabric after finishing for many times, its softness is remarkable. decline

[0005] At present, there is no silicone softener in the market that has both hydrophilic moisture permeability, yellowing resistance and cold feel. Most of the silicone oils on the market have characteristics in only one aspect.
