Spunbond non-woven production process to determine the dispersion of masterbatch

First, masterbatch poor dispersion performance
1, the metering pump pressure rise quickly
2, broken wire, gob serious
3, for short cycle components
4, non-woven surface floating silk, silk stigma more
5, non-woven uneven weight (weight CV% bigger)
6, non-woven fiber surface uneven thickness (fineness CV% bigger)

Second, the quality of masterbatch reflect
1, the process is easy to adjust, no significant change in pressure metering pump
2, the fiber net uniform, smooth, no fly, floating silk, gob phenomenon, without operator staring spinnerets or improper condition on non-woven
3, replaced long filter cycles, for a long period components to complete the task easily plan
4, woven from the beginning to the need to change the quality of the components, always stable, no significant differences in the quality of non-woven fabrics, but does not produce a lot of waste cloth or defective cloth
5, easy color change, cleaning materials less
6, non-woven fiber uniformity, weight evenly, uniform fiber distribution
7, the fibers under a microscope magnified observation 200-1000 times, good smooth performance, no black spots, large particle pigments, breakpoints, crack bifurcation fiber, etc., to increase fiber and non-woven breaking strength, drawing strength and other indicators critical

Third, the comparative analysis of different non-woven fabric Quality of masterbatch
1, a well-known enterprises in Shandong black non-woven
Fiber diameter of about 14μm
Fineness uniform and smooth, there are no large particles dispersed pigments, fiber surface without pits

 
2, a well-known enterprises in Shanghai black non-woven
Fiber diameter 15μm
Fineness uniform and smooth, there are no large particles dispersed pigments, fiber surface without pits

 
3, a domestic enterprise nonwovens
Problems:
①, fineness unevenness, the maximum diameter of 27.89μm, minimum diameter 14.45μm;
②, large particles are not dispersed pigment numerous;
③, fiber pits too much, not smooth;
④, net uneven

 
Third, the impact of the quality of the non-woven cost masterbatch
1, replaced the filter cycle length affect the cost. Filter is the cost
2, for the cost of the components affect cycle length. Also a ton of masterbatch, without the need to change some components, some change several times, each time for assembly takes labor, electricity, waste, and so the cost, about 2000-3000, which is the difference between the masterbatch than good masterbatch increase hidden costs 2000-3000 yuan per ton
3, non-woven quality. Use high-quality masterbatch will certainly produce high-quality non-woven, inferior inferior masterbatch will certainly produce nonwovens. Quality is the brand, the quality is the value, quality is the market, the quality is profit. Quality is not that your business will never pursue it?
4, filler added. Quality masterbatch, it will definitely add more filler, add 5% more filler masterbatch unit cost of non-woven fabric by about 400 yuan / ton.
5, labor costs. Quality masterbatch must reduce labor intensity, it must reduce labor costs

Fourth, the masterbatch use points to note
1. Check the masterbatch is dry, the moisture content will directly affect spinning
2, the measurement must be proofread accurately masterbatch, masterbatch business because of the additional amount must be provided by the weight ratio of the content, not the content of the volume ratio
3, the color must be in strict accordance with the production process to confirm the quality management program determines confirmation. Because different process conditions, different materials, different fiber fineness, a nonwoven fabric different weight, different roll temperature, nip pressure and shape, and so will have an impact on color
4, the occurrence of spinning is not normal, to analyze equipment, technology, operations and other issues still masterbatch problem, so quick to judge the analysis and processing
5, the filler will definitely have to use color color, hue produce different effects. Different manufacturers, different batches of different origin of the production of calcium carbonate filler will have an impact on color, non-woven production and technical personnel files must do to avoid unnecessary losses
6, matching masterbatch melt index is very important, especially meltblown masterbatch, masterbatch supplier to understand the masterbatch melt index meets the requirements of non-woven production
7, choose a stable and reliable supplier of particular importance. Because different masterbatch supplier of masterbatch production process is not the same, easy to have some impact on the stability of non-woven production enterprises stability, quality.
