Spunbond non-woven fabric technology and process; spunbond non-woven fabric refers to that after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the fiber web is then self-bonded and thermally bonded. Bonding, chemical bonding or mechanical reinforcement methods to turn the web into a non-woven fabric. It is characterized by high strength, good high temperature resistance (can be used for a long time in 150 ℃ environment), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth-proof, non-toxic.
Why is the production of pp non woven fabric machine environmentally friendly?
What are the inspection items of pp non woven fabric machine?
What is the application industry of pp non woven fabric machine?
In terms of environmental protection, the raw material of most of the non-woven fabrics currently used by pp non woven fabric machine is polypropylene, while the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are very different in chemical structure. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so it can be effectively degraded, and enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.
1. Internal quality inspection items: width deviation, mass deviation rate per unit area, coefficient of variation of mass per unit area, breaking strength, elongation at break, burst strength, equivalent aperture, vertical permeability coefficient, thickness,
2. Appearance quality inspection items: holes, poor trimming, color difference, joints, frit, foreign matter, poor auxiliary net, soft folds
3. Optional testing items: dynamic perforation, piercing strength, vertical and horizontal strength ratio, water flow in the plane, wet sieve aperture, friction coefficient, UV resistance, acid and alkali resistance, oxidation resistance, temperature resistance, wear performance, creep performance, flame retardant performance, splicing resistance, oleophobicity, hydrophobicity, elongation at constant load, load at constant elongation, elongation at break, etc.
PP non woven fabric machine can be divided into three categories: technical textiles, clothing textiles and home textiles according to their uses. Technical textiles refer to specially designed textiles with engineering structure characteristics, usually with good flexibility and processability. It is mainly used in medical and health, daily cleaning, environmental protection, safety protection, construction and transportation, aerospace and other fields. According to different product processing methods, technical textiles can be divided into non-woven, knitted, woven, multi-layer composite textiles and other sub-categories. Among them, non-woven technical textiles are non-woven fabrics.
