摘要

Functional additives, such as mineral and inorganic particles, added significant industrial value for processing lines such as extrusion and spinning. Within the scope of polymer processing loading mineral additives by compounded masterbatch in traditional polyolefin polymers potentially modify those structure bonding by thermal bonding. The large volume of inorganic phase adding raises questions about calcium carbonate as filler in the loading and embossing capacity, quality, and efficient bonding potentiality for relevant products. The process parameters have been recorded around this article on emboss temperature, calcium carbonate concentration, web thickness to carry out the hypothesis achievable in the spunbond system. Filler adding polypropylene has lower heat capacity, which transfers heat efficiently to achieve optimum bonding effect. Modulated differential scanning calorimeter (MDSC) characterizes heat capacity. Morphology of fabric has validated the circumjacent structure changes around the oval pattern. Finally, the conclusion has built a relationship between structure and heat capacity of the inorganic/organic phase, using an equation involving delta k(H phi Ca) Delta T and the heat capacity correlation with the dosage of CCF.
