Non-woven masterbatch what characteristics, it can be applied to what aspects, why so popular?

Nonwovens Masterbatch Product Features

(1) heat resistance; non-woven masterbatch the most basic requirements to withstand the temperature of polypropylene fiber production process, to maintain its performance stability. The spunbond temperature is 270-280 ° C, and the meltblowing is stabilized to 270 to 300 ° C.

(2) dispersibility; non-woven masterbatch should be excellent dispersion, and the use of dispersant does not reduce the quality of spunbond non-woven fiber. Otherwise it can not produce a good quality fineness of the fiber, the melt movement is not stable, easy to break in the drawing fiber or produce abnormal fibers.

(3) stability; non-woven masterbatch in the CaCo3, spunbond meltblown non-woven fiber to have excellent stability. Uniform particle size distribution, no more than 20 microns of large particle size impurities, etc., to ensure that the spunbond meltblown non-woven fiber excellent physical properties.

Nonwovens Masterbatch Product Use

Spunbond meltblown nonwovens fill the mother of the quality indicators include more content. Such as the appearance of the general size of 2 mm × (3 ~ 4) ㎜, melting point, DF value, MI value, heat and weather resistance characteristics.

(1) filtration performance; fiber grade spunbond meltblown non-woven with a filler to fill the performance of the parent filter to fill the quality of the masterbatch, the value of the value of DF, the value of small spinning process is relatively long replacement of the filter module, the general The DF value required to fill the master batch is less than 2.0 × 105 Pa · cm2 / g.

(2) melting point; spunbond meltblown non-woven fabric with a filler for the low molecular weight copolymer, so its melting point between 100 ~ 130 ℃.

(3) melt flow index (MI value); generally require spunbond meltblown non-woven with a filler master MI value of 20 ~ 100g / 10min.
