Custom production of Polyester fabrics for conveyor belts

Some technical characteristics of Polyester fabrics for conveyor belts are:



Polyester fabrics are synthetic polymers derived from the polycondensation of a carboxylic acid and an alcohol, and are the most common name for polyethylene terephthalate (PET).

These fabrics have excellent toughness and resilience, high resistance to abrasion, creasing and heat, high modulus of elasticity, low moisture regain and good resistance to chemical and physical agents.

These fabrics are often combined with other natural, artificial or synthetic materials, such as polyurethane or carbon spiral anti-static yarns, to obtain specific properties or effects.

These fabrics are used for conveyor belts that require high tensile strength, resistance to cutting and wear, flexibility and dimensional stability. They are suitable for use in ovens, air gravity conveying and general transport applications.

Polyester fabrics are also used for conveyor belts for industrial printers, where a very uniform and smooth surface is required for optimal printing quality.

Some of the industrial sectors that use polyester fabric conveyor belts are food, metalworking, textile, printing, packaging and logistics.



Polyester fabrics are synthetic materials that have many advantages over other fabrics, such as cotton, wool, silk, or nylon.



These fabrics are durable and lightweight, which means they can last longer and are easy to carry.

These fabrics are wrinkle resistant, which means they do not need ironing and can maintain their shape well.

They dry very quickly, which makes them ideal for outerwear or sportswear.

They take dyes easily, which means they can have bright and lasting colours and prints.

They are stain resistant, which means they are easy to clean and do not absorb dirt or liquids.

These fabrics are economical, which means they cost less than other synthetic fibers, such as nylon.

They can be combined with other materials, such as cotton, wool, nylon, or viscose, to obtain specific properties or effects.


The Purpose of Textiles in Conveyor Belting

Conveyor belts are the driving force in conveying operations. There are many different types and materials for the abundance of applications in the market. However, there are a few different textiles that serve an important purpose in conveyor belting.

Purpose of Textiles in Conveyor Belting

  • Provides Strength for Tensioning
  • Provides Strength for Handling the Load
  • Adds Rigidity or Stiffness, &#;Gives it Body&#;
  • Improves Mechanical Fastener Retention
  • Improves Wear Against the Conveyor Bed
  • Reduces Sliding Drag on Product or Conveyor Bed

Types of Textiles/Fibers Used in Conveyor Belting

Natural:

Cotton & Wool

Solid woven cotton is often used in baking applications where belts must &#;breathe&#;, absorb, and/or handle warm products. It is also used in applications to handle warm, green rubber products. Cotton is used in length, width, or in both directions of multiple plied conveyor belting to increase the bulk of the overall product on applications that require resistance to impact without requiring high strength.  Most commonly, it is placed either on the top or bottom ply of multiple plied belts to provide lower drag against the conveyor bed or some conveyed products &#; like cartons.

Characteristics & Properties

  • Moderate Strength
  • High Bulk &#; a course, thick fiber
  • High absorbing
  • Low modulus &#; high elongation
  • Low cut and abrasion resistance
  • Moderate temperature resistance
  • Low mildew resistance

Man-Made:

Synthetic &#; Aramid, Nylon, Polyester 

Nylon:

A nylon core is used to provide high strength as required in some flour, paper, box, and wood applications for conveying products or transmission of power. It is used as the width fiber (fill yarn) in conveyor belting to increase rip resistance and fastener retention as well as to resist abrasion from building material products.

Characteristics & Properties

  • High Strength
  • High Elasticity &#; Stretch and Shrink
  • Moderately Absorbing
  • Moderate elongation
  • High Cut and Abrasion Resistance
  • High Mildew Resistance

Polyester: 

Solid woven polyester is used as a durable and low-cost option for general conveyance, with specific uses in the parcel, package, and baggage applications. Polyester is used in the length (warp), width (fill), or in both directions of the weave as an inexpensive carcass for multiple plied conveyor belting. Spun polyester generates less noise and is used when higher speeds are used on long(er) slider bed applications.

Characteristics & Properties

  • High Strength
  • Low Elasticity &#; Stretch and Shrink
  • Moderately Absorbing
  • Moderate Elongation
  • Moderate Cut and Abrasion Resistance
  • Low-Temperature Resistance
  • High Mildew Resistance

Aramid (Kevlar):

Kevlar is used in glass applications where belts must withstand hot temperatures and retard flames, in heavy applications near industrial furnaces or conveying hot products being discharged from heat processes, and in heavy applications where resistance to high or heavy impact is important.

Characteristics & Properties

  • High Strength
  • High Bulk &#; A Coarse, Thick Fiber
  • High Modulus &#; Low Elongation
  • High Flame Resistance
  • High Impact Resistance
  • High-Temperature Resistance

Blending of Textiles

A blend of textiles is often used to gain the benefits of a variety of features that provide solutions and enhance belt performance or extend belt life.
