Loose net hair is made into wool strips through a carding machine (see carding machine). Testing items include component testing, fiber content testing, flame retardant performance testing, wool content testing, fiber content testing, etc. Physical indicators: fineness, fineness dispersion, length, length dispersion, and short fiber rate below 30mm. Appearance defects: standard weight, weight tolerance, weight unevenness, number of coarse particles, and number of grass chips. Detection scope: door and window wool, sealing wool, plastic steel wool, aluminum alloy wool, polyester wool, acrylic wool, etc
