Waxing:
The process of coating the fabric with a layer of wax is known as waxing. Waxing is done for water repellency.
Types of Waxes:
Vegetable Wax.
MC Wax. (Microcrystalline Wax)
Paraffin Wax.
Bee Wax.
Types of Waxing Process:
Kiss Waxing.
Normal Waxing.
Kiss Waxing: Waxing is done only on one side of the fabric with a truff roller setup.
Recipe:
Normal Waxing: Waxing is done by dipping the fabric in the truff i.e., both sides of the fabric are coated with wax.
Recipe:
The action of Chemicals:
Vegetable Wax: Water Repellency.
Aluminum Super Gel: To create Jelly texture.
ZnO: To break the Jelly substance created.
China Clay: Filling agent.
Anti-Fungal Agent: Antifungal Behavior.
Rice Bran Oil: Acts as Thinner.
Processing Parameters:
Wax temperature: wax is melted at 150oC.
Calendaring roller temperature: 110oC.
Machine Speed: Based on GSM.
Effect of Speed on Waxed Fabric GSM:
In the case of Kiss waxing with an increase in speed GSM increases. As the Roller speed increases add-on increases.
In the case of Normal Waxing with an increase in speed, GSM decreases, As the speed increases contact time decreases so that pickup decreases and GSM decreases.
Add-On Calculation:
For Waxing there will be no MLR, but the recipe is done based on addon percentage.
Add-On % = (Final GSM – Base GSM) X 100 / Base GSM.
Waxing Machine:
Zones in waxing machine.
Feed Zone: Fabric is fed in open from.
Waxing Zone: Waxing is done at this zone.
Drying/Calendaring Zone: Here Waxed fabric is dried or heat set.
Delivery Zone: Waxed Fabric is delivered in open width form.
