Baling twines are small diameter synthetic or sisal cloth strips used to bond a small amount of material to a straight and sturdy wire. The fabric must be sufficiently strong to withstand the force with which the wire is bent. Fitting of a baler twine can be achieved using several different techniques. These include the mechanical application of a strip of material, such as yarn, basting tape, or even glue, or pinching of the wire’s material, using pliers. The mechanical application is more commonly used for baler twine installations where a tight, secure bond is desired, such as in applications involving delicate electrical wires.
Tapping or impressing a straight edge into the material to be bonded using the baler twine causes the straight edge to become weaker. The bonding process becomes much less effective. This is because the tool’s tap changes the strip’s mechanical properties, making the bond weaker and shorter-lived. A far better approach is to apply the bond in one fell swoop using a twisting motion from the opposite direction as the wire is twisted and applied to the strip. This results in a stronger bond that will stand a good chance of withstanding even the most extreme conditions.
Baling twines are constructed out of different materials depending on their application. Some of the common materials include polypropylene, nylon, polyester, polystyrene, polyester, and acrylic. These materials can be combined to make innovative and exciting designs, but each material also exhibits the characteristics that make it appropriate for specific applications. For example, polypropylene is the ideal raw material for making a small diameter sisal string due to its exceptional elasticity, strength, and durability. It is also the ideal material for making small diameter beads because of its high water permeability, which allows the bead to expand upon immersion into water.
Nylon is the ideal raw material for making a thick string because of its high tensile strength and excellent fire retardancy. The string is also very flexible and robust, which allows it to stand up against several aggressive challenges. Due to this strength and flexibility, nylon strings are commonly used in conjunction with polypropylene strings. Many dygrafies use nylon strings as a significant component of their construction.
Polystyrene is a material that is both lightweight and strong, making it an excellent choice for a material used in making a large variety of small diameter sisal bags. The bag’s ability to expand allows the bag to take on any shape, including an oblong shape that resembles a football. A bale of polystyrene that has been tightly wound will eventually collapse, but a well-wound baler twine can withstand greater force. This type of bale is useful for making bales for hay or wood chips.
