This research paper reports a study on thermal and sound insulation samples developed from garment waste recycled cotton/polyester fiber (recycled cotton/PET) for construction industry applications. In this research work, the piece of clothing waste recycled cotton and polyester fiber is a potential source of raw material for thermal and sound insulation applications, but its quantities are limited. To overcome the above problems, apparel waste recycled cotton fiber was mixed with recycled/PET fiber in 50/50 proportions in the form of two-layer nonwoven mats with chemical bonding methods. The samples such as cotton (color and white), polyester (color and white), and cotton–polyester blend (color and white) were prepared. All the samples were tested for thermal insulation, acoustic, moisture absorption, and fiber properties as per the ASTM Standard. Also, the behavior of the six recycled cotton/polyester nonwoven samples under high humidity conditions was evaluated. The sound absorption coefficients were measured according to ASTM E 1050 by an impedance tube method; the acoustics absorption coefficients over six frequencies of 125, 250, 500, 1000, 2000, and 4000 Hz were calculated. The result revealed that recycled/PET/cotton garment waste nonwoven mats were absorbing the sound resistance of more than 70% and the recycled nonwoven mats provided the best insulation, acoustic, moisture absorption, and fiber properties. The recycled pieces of clothing waste cotton/polyester nonwoven mats have adequate moisture resistance at high humidity conditions without affecting the insulation and acoustic properties.

服装废料回收的棉/聚酯气流成网非织造布的热和声特性

本研究报告报告了一项关于从服装废料再生棉/聚酯纤维(再生棉/ PET)中提取的隔热和隔音样品的研究,以用于建筑行业。在这项研究工作中,一块废衣物再生棉和聚酯纤维是隔热和隔音应用的潜在原材料来源,但数量有限。为了克服上述问题,将服装废料再生棉纤维与再生/ PET纤维以化学粘合方法以两层非织造垫的形式以50/50的比例混合。准备了样品,例如棉(彩色和白色),聚酯(彩色和白色)和棉涤混纺(彩色和白色)。根据ASTM标准,对所有样品进行了隔热,隔音,吸湿和纤维性能测试。而且,评估了六个再生棉/聚酯非织造样品在高湿度条件下的行为。吸声系数是根据ASTM E 1050通过阻抗管法测量的;计算了125、250、500、1000、2000和4000 Hz六个频率上的吸声系数。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。评价了六个再生棉/聚酯非织造样品在高湿度条件下的性能。吸声系数是根据ASTM E 1050通过阻抗管法测量的;计算了125、250、500、1000、2000和4000 Hz六个频率上的吸声系数。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。评价了六个再生棉/聚酯非织造样品在高湿度条件下的性能。吸声系数是根据ASTM E 1050通过阻抗管法测量的;计算了125、250、500、1000、2000和4000 Hz六个频率上的吸声系数。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。吸声系数是根据ASTM E 1050通过阻抗管法测量的;计算了125、250、500、1000、2000和4000 Hz六个频率上的吸声系数。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。吸声系数是根据ASTM E 1050通过阻抗管法测量的;计算了125、250、500、1000、2000和4000 Hz六个频率上的吸声系数。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。结果表明,回收的/ PET /棉服装废料非织造垫吸收了超过70%的声阻,并且再生的非织造垫提供了最佳的隔音,隔音,吸湿和纤维性能。衣物废棉/聚酯非织造垫的回收件在高湿度条件下具有足够的耐湿性,而不会影响绝缘和声学性能。
