SIZING PROCESS |
1. Preparing the Sizing Solution
The sizing solution is typically made of adhesives, softene
rs, and other additives. The most commonly used materials include:
- Adhesives: Starch, polyvinyl alcohol (PVA), or carboxymethyl cellulose (CMC) to provide strength.
- Softeners: Oils, waxes, or glycerin to improve flexibility and reduce brittleness.
- Antistatic Agents: To reduce static electricity during weaving.
Steps:
- Mix the ingredients in water, ensuring they dissolve completely.
- Heat the mixture to the required temperature to form a homogeneous solution.
- Maintain the viscosity and concentration as per the yarn type and weaving requirements.
2. Yarn Preparation
Before sizing, the yarn must be clean and properly aligned. This involves:
- Warping: Arranging yarns in parallel order.
- Cleaning: Removing dust, loose fibers, or impurities.
3. Sizing Application
The sizing solution is applied to the yarn using a sizing machine. This process includes:
- Immersion: The yarn passes through a sizing bath containing the prepared solution.
- Squeezing: Excess solution is removed using rollers to ensure uniform application and prevent overloading.
- Drying: The yarn is dried using hot air or heated rollers to fix the size on the yarn surface.
4. Stretch and Tension Control
Maintaining proper tension during sizing is critical to avoid yarn breakage or uneven sizing. The tension should be adjusted according to the yarn's properties (e.g., elasticity, thickness).
5. Post-Sizing Treatments
Once sized, the yarn undergoes further processes to ensure it is ready for weaving:
- Cooling: Allow the yarn to cool after drying.
- Beam Winding: Wind the sized yarn onto a warp beam for the weaving process.
6. Quality Control
Regular checks are essential to ensure the sizing process meets quality standards:
- Evenness: Check for uniform application of the size.
- Strength: Test the tensile strength of the sized yarn.
- Hairiness: Measure the reduction in yarn hairiness.
- Adhesion: Ensure the size adheres well without flaking.
