First, the natural fiber
There are a wide variety of fibers, the earliest use of natural fiber, the so-called natural fiber, which is, such as bristles, wool and the like directly collected rather than synthetic materials.
Pig mane from the pig body, in general, a pig can only take hair once a lifetime. Bristles can be used to make a variety of brushes, the most common is the bristles paint brush. The bristles are shaped like hair from the root to the end, from coarse to fine, so that the bristles have good elasticity; in addition, the ends of each hair will be slightly bifurcated; common bristles are brown (white) or black. Bristle durability and excellent water resistance, but also anti-static, high temperature and acid.
Wool is relatively soft, slightly less flexible, made of wool brush, used to brush paint will not leave the brush marks. In addition to making paint brush, the wool is often used in hair short and soft brush, such as cosmetic brush.
3, horse hair
Horse hair softness between the bristles and wool between the horse tail hair will be slightly harder than the bristles; horse hair toughness, wear resistance, but not acid, made of brush used in polished, clean, dust And other related industries; to Ma hair for the material of the brush can withstand about 190 degrees Celsius high temperature.
Palm fiber is made of some of the fibers of agave and stems and leaves made of fibers, the main production from Mexico, so the line called "Mexican Tampico"; palm fiber anti-acid and alkali performance is good; because it is plant fiber so absorbent Good; white brown can be about 140 degrees Celsius temperature, suitable for the manufacture of leather details of the polishing brush polishing operations.
In addition, there are sisal, is also used to process the brush one of the natural materials, sisal performance and white brown similar, but also used to process into a polishing brush, finished known as "sisal."
Second, man-made fibers / synthetic fibre
PA, PP, PE, PBT, PET, PVC and other plastic monofilament, these materials due to low production costs, diverse colors, stable quality, length is not limited, etc., in the modern brush processing was Widely used, especially on industrial brushes, these man-made filaments use much more than natural wool.
In the above-mentioned man-made materials, nylon (PA) is the largest amount of use, but also the most classified, nylon wire due to the characteristics of the differences, divided into the following:
Nylon 6 (PA6): nylon 6 in the nylon family is the best price cheap, however, nylon 6 still has a good recovery, temperature and wear resistance. The wool is thus widely used in a variety of brush products, the market is the most common fibers.
Nylon 66 (PA66): Compared with nylon 6, nylon 66 in the same diameter, its hardness, restorability, wear resistance are slightly better, temperature up to 150 degrees Celsius.
Nylon 612 (PA612): nylon 612 is a relatively high quality nylon yarn, its low water absorption, recovery and wear resistance than nylon 66 is even better. In addition, nylon 612 has anti-mold and anti-bacterial characteristics, it’s made brush wheel, brush bar, etc. are often used in food, medical, electronics-related industries.
Abrasive nylon: abrasive nylon is nylon 6 or nylon 612 for the brush wire raw materials by adding silicon carbide (SIC) or alumina (AO) abrasive particles after the synthesis of silk, the industry also into abrasive silk or grinding wire, the resulting brush Finished with wear characteristics, according to the diameter and the number of different ways.
The above is a common type of nylon, in addition, the following is the use of other large artificial brush fibers.
PP: PP is the biggest characteristic of the density is less than 1, in the test wool material when the number of its preferred in the water, if floating on the surface can be initially determined as PP material; PP hair cross section oval; In addition, PP flexibility Poor, many times after the bend is difficult to restore the original; can be heat up to 120 degrees Celsius.
PET: PET has a good resistance to acid and alkali, alcohol, gasoline, benzene and most of the cleaning solvent, both a considerable antibacterial, not mildew.
PBT: PBT monofilament with acid, oil, solvent resistance, etc., but easy to hydrolysis at high temperatures.
PVC: PVC low cost, short service life, poor wear resistance, so the industrial brush less PVC as fiber, in order to avoid frequent replacement of the brush. PVC brush wire can be made of front fork, the industry known as the "flowering silk", commonly used in brooms and other household cleaning brush.
