The Importance of Choosing the Right Rubber Coating for Cylinder Compactors in Tangential Winding Machines and its Impact on Fabric Roll Quality

At Textape, we understand that the quality of fabric rolls is a fundamental aspect of the textile production process. One of the most critical steps in this process is the compaction of yarns and fabrics using tangential winding machines, a phase that directly influences the final product’s quality. The rubber coating on the cylinder compactor plays a crucial role in this process. Selecting the right coating is not only essential for the machine’s efficiency but also for achieving the desired fabric quality.

The Role of the Cylinder Compactor and Tangential Winding

Tangential winders are used to shape fabric rolls by managing the tension and rewinding during production. The cylinder compactor is a key component of these machines, as it ensures the compaction of the yarns or fabrics, directly affecting the fabric’s density and surface appearance.

Tangential winding guarantees an even fiber distribution and optimal tension, both critical for fabric quality. However, to ensure top performance, the cylinder compactor must be equipped with a rubber coating that meets specific technical and production requirements.

The Crucial Choice of Rubber Coating

Choosing the right type of rubber coating for the cylinder compactor is a step that requires great care. The coating directly impacts several important factors:

1. Grip and Adhesion: The rubber must provide the right level of adhesion between the cylinder and the fabric. A coating with too much grip can damage the fabric, while too little can undermine the compaction process.
2. Durability and Resistance: The rubber coating must withstand the wear and pressure encountered during the winding process. Abrasion resistance is key to maintaining consistent performance over time and ensuring the longevity of the machinery.
3. Elasticity and Flexibility: Rubber that is too rigid may hinder the proper deformation of the cylinder, while excessively elastic rubber might fail to provide uniform compaction. Achieving the right balance in elasticity is essential to adapt to varying fabric types and tension changes during winding.
4. Surface Finish: The surface of the rubber coating must be designed to meet the specific needs of the production process. It can be smooth or textured, depending on the type of fabric and the desired surface effect. A smooth surface ensures even compaction, while a textured one can impart unique finishes to the fabric, enhancing its tactile qualities.

 

Smooth Belt vs. Textured Belt

At Textape, we offer both smooth belts and textured belts for cylinder compactor coatings. These two options influence the fabric’s characteristics in different ways:

• Smooth Belt: Ideal for fabrics that require a smooth, uniform surface, the smooth belt provides even compaction, producing high-quality fabrics with consistent finishes. However, a smooth surface may not be suitable for fabrics that need specific textures or high tension.
• Textured Belt: A textured surface is achieved through a grinding process that creates patterns on the rubber. This option is ideal for fabrics requiring a special finish, such as a rough or decorative surface. Grinding also enhances grip during compaction, preventing slippage and improving performance.

The choice between smooth or textured belts depends on the specific fabric being produced. For delicate fabrics or those requiring a uniform finish, a smooth belt is the best choice. For more structured fabrics or those with a unique texture, a textured belt is more appropriate.

The Importance of Grinding and Polishing

Grinding, also known as polishing, is a process that creates a textured surface with specific properties based on the fabric requirements. This process enhances the belt’s grip and abrasion resistance, ensuring better durability compared to a smooth belt.

It’s important to note that improper grinding can compromise the quality of the fabric and reduce the coating’s lifespan. At Textape, we focus on precision grinding, using high-quality abrasives to achieve an optimal surface finish that aligns with the production needs.

Bonding the Rubber Coating: Adhesive Selection

An essential part of the process is bonding the rubber coating to the cylinder itself. The adhesive must be carefully chosen to ensure stable and durable adhesion, capable of withstanding mechanical and thermal stress during operation.

At Textape, we use high-performance adhesives suitable for various operating conditions, such as temperature, humidity, and pressure, to ensure optimal bonding. Polyurethane and epoxy adhesives are commonly used for their durability and resistance to wear and deformation.

A key aspect of adhesive bonding is curing time. Every adhesive has specific drying and curing times that must be followed to ensure perfect adhesion. If these times are not respected, the coating may detach during operation, compromising the production process. On the other hand, excessive curing time could delay production. We at Textape ensure that all adhesives are applied with precise timing, adhering to the recommended curing processes for optimal performance.

 

Cleaning the Cylinder Compactor

Cleaning the cylinder compactor is a vital aspect of maintaining the quality of the rubber coating and ensuring consistent fabric production. Residues such as fabric remnants, dust, oils, or other

contaminants can accumulate on the cylinder surface, which can negatively impact the rubber’s performance and the fabric’s quality.

At Textape, we advise regular and thorough cleaning of the cylinder. The cleaning process should use appropriate agents that effectively remove contaminants without damaging the rubber coating or the cylinder surface.
