一、国内外非织造布发展概况 非织造布,又称无纺布。早期较低档的非织造布由于原料成本高,生产工艺复杂,发展大大受到限制,直至七十年代全世界非织造布总产量仅约21万吨左右。随着纺粘法、熔喷法、水刺法等新工艺相继问世,生产技术的不断改进和提高,在世界范围内出现了非织造布迅猛发展的势头,其发展速度大大超过了纺织工业的平均速度。至一九九零年,全世 First, the development of non-woven fabrics at home and abroad Non-woven fabrics, also known as non-woven fabrics. The early lower-grade non-woven fabrics had high raw material costs and complicated production processes, and their development was greatly restricted until the 1970s when the total production of non-woven fabrics in the world was only around 210,000 tons. With the advent of new processes such as spunbonding, meltblowing, and hydroentanglement, and the continuous improvement and improvement of production technology, the rapid development of nonwoven fabrics has emerged in the world, and its development speed has greatly exceeded that of the textile industry. Average speed. To 1990, the whole world
