1. What is silicone softener
—-Upscale Softness Finishing Solution
All fabrics from natural to synthetic fiber, they need a hand to promote its comfortable feeling, Soft, Smooth, Fluffy, Elastic, Bulk, Gloss,Full.. Therefore, fabric softening treatment has become an important part in textile processing.
Once produced, fibers can be treated with silicones to impart initial softness to the textiles made from these fibers. Softening is considered to come from the siloxane backbone flexibility and the freedom of rotation along the Si-O bonds. This allows exposure of the low interacting methyl groups, reducing fiber-to-fiber interactions. To enhance durability through multiple wash cycles, some methyl groups can be replaced on the silicone polymer by other functional groups to increase the silicone softener attraction to, and interaction with, the fibers to be treated.
In this respect, amino-functional groups like -CH2-CH2-CH2-NH-CH2-CH2-NH2 are particularly popular for increasing physical adsorption and providing better softening properties.
2. Features of silicone softener
Excellent hand feeling including collection and preference of softness, smoothness, fullness, elasticity……
Spectacular hydrophilicity for various fabrics including cotton,flax, viscose, polyester, polyamide and any other you are using
Very good stability under hard process condition and compatibility, no stick to roll, no float oil……
No yellowing problem, not change color and impact whiteness
Absolute high cost-performance and good properties by using less usage to achieve same and better effect
3. Questions about silicone softener
3.1. How to measure hand feeling and other properties? Hand feeling can be data-oriental simply?
Hand feeling can not be measured by device simply, some index of the data can roughly show its hand feeling, like solid content, etc. However, final hand feeling is evaluated by experienced expert through a series of touch and feeling. Therefore, it’s a sensory evaluation.
3.2. Which factors will lead to non-ideal results?
Firstly, different softeners have matched emulsification system and emulsifier to optimize effect, therefore, please do test according to the instruction of the providers.
Secondly, the quality of emulsifier will affect the emulsion effect, therefore, please strictly source high quality emulsifier.
Thirdly, finishing treatment is a step in textile processing, before and after finishing process, the fabrics have been handled by many procedures, there are tens of thousands of chemical molecule into fabrics. It’s quite possible to have chemical reaction rejection reaction with softeners. Therefore, it causes softeners could not exert effect. For some kinds of silicone softeners, they have limited compatibility with anionic textile auxiliaries, so compatibility tests should be carried out before it is used together with other chemicals.
Please read the relevant operating procedures before testing.
