This tapered natural fiber with very thick butts and split ends (flags) is used primarily in brushes that require the ability to carry liquids. Pig bristle is used primarily in the paint brush industry for oil-based paints, as it carries and releases the paint very well. It is also used in very fine car or truck wash brushes, because it carries the soap very well and does not scratch the surface. Finally, it is used in higher quality hair brushes, as it carries people´s natural oils well.
Bristle comes in Grey (black and white), Black, or White, and is sold according to origin and dressing. MFC prides itself in having the ability to provide its customers with dressed bristle and/or the bristle mixtures that they require for their applications.
For the paintbrush industry, different sizes of bristle can be mixed together with the butt ends facing the same side, in order to allow the manufacturer to produce a paintbrush according to his specifications.
MFC can also re-sterilize the bristle, cut the bristle from different sizes and mix it with itself or with other fibers (synthetics at times), in order to achieve the stiffness and cost specified by our customer, that can be used in an application that requires its special characteristics.
WHERE DOES BRISTLE COME FROM AND WHAT IS THE DIFFERENCE BETWEEN ORIGINS?
Bristle comes primarily from China (Chung King, Hankow, Tiensen, Tsingtao). The origin affects the stiffness of the bristle. Chung King being the stiffest and Tsingtao being the least stiff. The stiffer bristle is considered to be of the highest quality and is priced accordingly.
WHAT DOES THE TERM “% OF TOPS” MEAN?
When one refers to % tops, one refers to the % of fibers that reach the top length. For example, if you buy 121mm 90% tops, then 90% of the fibers in the bundle should be 121mm.
WHAT IS THE DIFFERENCE BETWEEN BOILED AND UNBOILED BRISTLE?
Unboiled bristle is actually boiled one time in order to achieve sterilization. Boiled bristle is actually boiled twice. The second boiling is done with the bristle being in cups, which helps the bristle stay straight.
WHAT CAN I EXPECT AS FAR AS PRICING?
The price of bristle is dependent on the the quality, boiling, and the % of tops, and processing.
