The relationship between surfactant structure and soft property Among the surfactant softeners, cationic surfactants have a strong adsorption effect on the surface of the fiber, and its directional alignment is relatively tight, which leads to the best effect. The influence which Hydrophobic - based carbon chain makes to soft effects,can be thought of: C - C key can circle within a single bond and make the long chain into a curl of an irregular arrangement while keeping the bond Angle 109 DHS 28 cases. The molecular long chain has softness. Thanks to the softness, extension and contraction performance was attached to it when it is under the action of external force. In this way, the molecular of the softener plays a lubricating role on the surface of the fiber, reducing the dynamic and static friction coefficient between the fibers and the fibers, increasing the smoothness and softness of the fabric. The effect of hydrophobic structure The hydrophobic group is a surfactant with a ...

1. Being designed specially, the molecular structure can solve the technical bottlenecks, poor stability, which is common in the market, of the silicone polyether polyester amide combining various organic groups together,such as organosilicon, polyether, amide and polyester and in this synthesis process, adding organic amine can polymerize into silicone softener oil with new structure, and it is stable. 2. Polyether hydrophilic exists in the structure of multi copolymerization epoxy silicone,so there is no need to use expensive ED series polyether amine in block subsequent polymerization,which effectively reduce the cost of raw materials of silicone softener oil and avoid the problem that some domestic polyetheramines conversion rate is unstable. 3. Because of its high reaction activity,the amount of organic solvents can be reduced a lot.Generally only 5% - 20% copolymerization of epoxy silicone oil quality of can be carried out with high content of reaction uniform transparen...

We have discussed about some common quality problems occurred in dyeing when related to textile auxiliaries. here let's talk about these quality problems happened in textile finishing process. 1. The common quality question in soft finishing The soft finishing style is depended on the different customer’s requirement, such as soft, smooth, fluffy, soft waxy feel and slippery. We should choose different softener according to different style. For example, among the sheet-like  textile softener , there are different types, and their structure is different. And their soft, fluffy, slide, yellowing and water -absorbing ability to fabric is different. And among  silicone oil , the property of modified silicone oil made from different modified gene is different. For example, the property of amino silicon oil, hydroxyl silicone oil, epoxy modified polysiloxane, Carboxy Modified Silicone Oil is different. 2. Yellowing Amino sheet-like textile softener and amino silicone oil easy to...
