Dokusuz yüzey sektöründe spunbond kumaşlar, en çok kullanım olanağı olan kumaşlardır. Bunlardan bazıları çocuk bezi üretiminde kullanılmaktadır. Ancak kumaşların kullanım yerine göre sıvı geçirgenliği ve geri ıslatma miktarı özellikleri önem arz etmektedir. Bu sebepten spunbond kumaş üreticileri hidrofilik kimyasallar kullanmaktadır. Bu çalışmada, 4 farklı kimyasal, 2 farklı çözelti oranı ve 3 farklı besleme hızı ile spunbond kumaşa aplike edilmiş ve kumaşların performansları incelenmiştir. Sıvı emiş süresi, geri ıslatma miktarı ve tüketilen kimyasal miktarı göz önüne alınarak bir işletme için en uygun kimyasal ve çözelti oranları seçilmiştir.
Spunbond method is widely used in the production of nonwoven fabrics. Melt flow index (MFI) is one of the most important polymer processing parameters. In this paper, tensile strength and elongation values of spunbond fabrics with four different weights produced from polypropylene polymers with two different MFI values were measured. Tensile strength tests were analyzed by two-way multiple variance analysis (Two-Way Manova) in the SPSS statistical package program, and the effects of MFI and weight values on the strength properties of spunbond textile surfaces were examined. As a result of the statistical analysis, it was observed that statistically significant differences (p < 0.05) occurred in both tensile strength and elongation values with the change of weight value. In addition, significant differences (p < 0.05) occurred in tensile strengths with the change of MFI value, but the differences in elongation values were not statistically significant (p > 0.05).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
