| INFLUENCE OF PROCESSING PARAMETERS AND POWDER BINDER CONTENT ON PROPERTIES OF HIGH LOFT NONWOVEN FABRICS |

| 摘 要： | In this paper, the influence of processing parameters and powder binder content was studied and analysed on the properties of high loft nonwoven fabrics mainly using statistical analysis method. The relationship between the bulkiness and the warmth retention property was also tested. The analytical results reveal that the increase of the powder content, heating temperature and pressure will affect the tensile strength of nonwovens. Moreover, there are interactions between these parameters. The compression properties only change a little for a powder binder content of 15％—20％. However, with the increase of the heating temperature and pressure, the bulkiness and compression rate will reduce significantly. For the bulk density of high loft nonwoven fabrics, there exists a heat transter mechanism of air convection, but the higher the bulkiness of nonwovens, the larger the thickness and the better the warmth retention property of nonwoven fabrics.

| Abstract: | In this paper, the influence of processing parameters and powder binder content was studied and analysed on the properties of high loft nonwovcn fabrics mainly using statistical analysis method. The relationship between the bulkincss and the warmth retention property was also tested. The analytical results reveal that the increase of the powder content, heating temperature and pressure will affect the tensile strength of nonwovens. Moreover, there are interactions between these parameters. The compression properties only change a little for a powder binder content of 15%-20%. However, with the increase of the heating temperature and pressure, the bulkincss and compression rate will reduce significantly. For the bulk density of high loft nonwoven fabrics, there exists a heat transfer mechanism of air convection, but the higher the bulkincss of nonwovens, the larger the thickness and the better the warmth retention property of nonwoven fabrics. |
