The influencing factors for the fiberglass mat

There are so many factors influence the uniformly of fiberglass chopped strand mat, totally it can be divided into raw silk, equipment, environment, and human factors and so on.

Raw silk quality factor

The raw silk used in fiberglass mat machines must be fully drying and qualified. It’s density and stiffness preferably 100mm or more.

The fiberglass yarn density

When we don’t consider the waste yarn and mat, theoretically, when the cutter speed and movement speed is stable, the yarn density is a factor that influence the quality of unit weight of fiberglass chopped strand mat.

Oil content

If oil content less or uneven, the yarn stiffness will low, this will cause poor technical performance of yarn. When chopped, if the knife to cut the bad cluster tow, after cut off that the decapitation bifurcation serious filamentous, tangle together to form a dispersion not open beam filament, yarn balls appeared on the surface of the mat. It is different from the electrostatic beam filament appearance. Sometimes it inserted in the mesh belt when it down, and in the mesh belt formed a packet hollow, after cold forming holes in the mat surface.

Beam filament bundle through slotted generated, beam drawing process efficiency is bound to affect the uniformity of the unit area weight of the mat.

Environment factors

Keep the range of temperature and humidity in the creel room and molding chamber. It has a decisive impact for prevent the generation of static electricity. Suitable temperature is 20-24 ℃, relative humidity of 70% to 80%.
