WAXING IN TEXTILES || TYPES OF WAXES || TextileCoach




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:

  1. Kiss Waxing.

  2. 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.

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.
