How to choose silicone oil softening agent reasonably?

The secondary ammonia and linear body (WS-62M) ring hexyl amino silane coupling agent as raw materials, synthesis of amino silicone oil, then with polyether the of hydrophilic modification and preparation of polyether modified amino silicone oil.
Necessity of organic silicon finishing
Softener in fabric style, soft and comfortable to wear, played a pivotal role, traditional silicone softener because of the single function, difficult to balance apparel hand feeling, beautiful and comfortable requirement, has been unable to meet the people's increasing needs. Therefore, the preparation of new type of functional diversification of silicone softening agent gradually become the pursuit of modern textile finishing. Amino polyether modification and block instead of organosilicon softening agent has good comprehensive properties, textiles after the finishing, not only to get excellent softness, and keep good whiteness and hydrophilic, in order to meet the demands of clothing beauty and healthy and comfortable.
The rational choice of silicone softening agent
In normal circumstances, the choice of different fabrics for amino silicone oil is:
Cotton and blended knitted fabric, woven fabric, with soft feel, can choose the 0.6 ammonia value of amino silicone oil;
Pure polyester fabric, in order to smooth feel, can choose 0.3 ammonia value of amino silicone oil;
Silk knitted fabric, woven fabric, with a smooth touch, to the high gloss requirements, the main choice of 0.3 ammonia value of amino silicone oil, a combination of smoothing agent added luster;
The wool and blended fabric, soft, smooth, elastic demand comprehensive feel, little shade change. Can choose 0.6 ammonia value and 0.3 ammonia value of amino silicone oil compound products, some varieties can be used to increase the mixture of smooth and luster;
The cashmere sweater, cashmere fabric, wool fabric is high than the comprehensive handle, can choose high concentration compound products;
The nylon socks, to feel smooth, high elastic amino silicone oil;
Seventhly, acrylic raschel blanket, acrylic yarn and blended yarn, soft, high requirements for flexibility, choosing values of 0.6 ammonia amino silicone oil, taking into account the elastic demand;
The hemp fabric (flax, ramie) to smooth, the main choice of 0.3 ammonia amino silicone oil;
9 rayon, cotton with soft handle, can choose 0.6 ammonia amino silicone oil;
The polyester reducing alkali fabric, mainly to improve the hydrophilicity of the fabric, choose polyether modified silicone oil (CGF) is by methyl containing hydrogen silicone and end with unsaturated bond polyethylene glycol, poly propylene glycol polyether silicon hydrogen addition reaction made of. But the softness is poor, the new polyether modified silicone oil in the silicon oxygen chain, the introduction of reactive epoxy groups, etc., to improve the feel and durability of the fabric.
Silicone softening agent is a material that can increase the softness of the fiber material. Good performance of the soft agent can also make the fiber to get a special feel, to give the product a different finishing style, improve the quality and added value, increase clothing wearing comfort. Industrial use of soft agent can be divided into oil type, surface active dosage form, reaction type and polymer type four main types according to their main active ingredients. Early use of soft agent mainly for the first 3 categories, into the 70's after the development and use of polymer softening agent soon attracted people's attention, and become the mainstream of soft finishing. In the polymer type softening agent series, the performance of silicone softening agent (main component is the organic silicone) is the best and the yield is the biggest. According to statistics, the world is currently used in the textile finishing agent of the silicone about 150000 tons, of which 70% ~ 80% of soft agent.
