Abstract

This study explores the tensile properties of wet-laid nonwoven fabric made from softwood bleached kraft pulp (SwBKP), hardwood bleached kraft pulp (HwBKP), dissolving pulp (DP), and Lyocell. Five different ratios of wood pulp and Lyocell (0/100, 10/90, 20/80, 30/70, 40/60, and 50/50) were manufactured using papermaking technology, which is similar to wet-laid technology. The results indicate that the properties of strength and surface softness of a nonwoven fabric are enhanced by the contribution of the entanglements of wood pulp–Lyocell. Of the three pulps, SwBKP is superior to both HwBKP and DP on account of its higher properties of density and tensile strength, which are increased by refining treatments. In terms of the surface softness component results, HwBKP has a lower MMD value than the other samples. The SwBKP–Lyocell mixing ratios with the minimum ratio of 30/70 were found to offer sufficient tensile strength with improved softness.

摘要

本研究探讨了由针叶木漂白牛皮纸浆 (SwBKP)、阔叶木漂白牛皮纸浆 (HwBKP)、溶解浆 (DP) 和莱赛尔纤维制成的湿法成网无纺布的拉伸性能。木浆和莱赛尔的五种不同比例（0/100、10/90、20/80、30/70、40/60 和 50/50）是使用造纸技术制造的，这类似于湿法成网技术。结果表明，木浆-莱赛尔纤维缠结的作用增强了非织造布的强度和表面柔软度。在三种纸浆中，SwBKP 优于 HwBKP 和 DP，因为它具有更高的密度和拉伸强度，这些性能通过精炼处理得到提高。就表面柔软度分量结果而言，HwBKP 的 MMD 值低于其他样品。
