Properties of Reactive Softener: The properties of reactive softener are given below.
- Reactive softener can be applying on all types of fibers.
- Reactive softener reacts with –OH group of cellulose and form covalent bond and gives permanent finish.
- Its washing fastness is good.
- It is soluble in water.
- After application, it needs to cure.
Methods of application: Pad – dry- calender method is used to apply the reactive softener. This could be done as the follow. It is a sample application parameter.
Reactive softener : 25 – 30 g/l
Temperature : 900C
Curing : 1400 – 1500 C
Time : 4 – 5 minutes
Advantages and Disadvantages of Reactive Softener: Advantages and disadvantages of reactive softener are given below.
Advantages of Reactive Softener:
- The softening effect of reactive softener is durable.
- It does not cause yellowing problem.
- In case of resin finished fabrics, it minimizes the loss in tensile strength, tear strength and abrasion resistance.
- Application is easy.
Disadvantages of Reactive Softener:
- The reactive softener is comparatively costly than other softener.
So, from the above, we see that, reactive softener is reliable to apply to all kinds of fibers but it is more costly than other softening agents.
