Many manufacturers are prone to breakage when flocking, but this is actually related to the tension value. The most commonly used nylon and polypropylene filaments in the brush making industry are nylon and polypropylene filaments, which has a higher tensile strength?

Tensile strength is the maximum breaking force of a single wire under certain conditions. Nylon filaments are the better quality bristle material, with excellent overall performance, therefore high tenacity, high abrasion resistance and no breakage, especially suitable for use in objects with high tensile strength requirements.

Polypropylene filaments are at the lower end of the spectrum and are more often used in low-end cleaning brushes such as toilet brushes, disposable toothbrushes, road cleaning brushes and conductive brushes. The advantages of polypropylene filaments are their high hardness, acid and alkali resistance, low water absorption and low unit cost. The disadvantage is that they are not very resilient and are commonly used in toilet brushes, sanitation brushes and industrial cleaning brushes.

The influence of tensile strength on the flocking is that a qualified brush filament with tensile strength can effectively reduce the pull-off rate during the use and flocking process. Therefore, it is important to choose the right brush filament according to the product application area to improve the success rate of flocking.
