A nonwoven web refers to web structures that have been bonded together by entangling the fibres via mechanical, chemical or thermal bonding. Cotton waste has turned into a major threat to both environment and textile manufacturing due to the ever increasing world growth and population. Hence, the overture of this subject is to reuse and transform wastes, particularly cotton waste fibres, into raw product to cut down wastes and to reduce burden towards surroundings. In addition, the physical and mechanical properties of the cotton waste nonwoven web were studied in order to propose the possible end used. This study involves the production of cotton waste nonwoven web by using the needle punching method. The cotton waste fibres were needle-punched with various fibre feeder speeds of 1.8 m/s, 2.2 m/s, and 2.8 m/s. These speed parameter were chosen based on the machine capability. The types of needle loom and needle density used were kept constant. The produced webs were layered into four, five and six layers of stacking and punching process was repeated to enhance compactness of the web. Physical and mechanical analyses, such as web thickness, web areal density, web porosity, bursting strength test, puncture resistance test, and tensile strength test, were assessed. Analysis of Variance (ANOVA) and Design of Experiment (DOE) via Minitab software were utilized for statistical examination to support the experimental outcomes. The outputs revealed that the optimum fibre feeder speed to produce a thick and compact cotton waste nonwoven web properties was 2.8 m/s with six layers of stacking. The results of the mechanical properties of the cotton waste web appeared to vary. The web with highest bursting properties denoted by S1L4 (11 kgf) and highest puncture resistance properties is represented by S2L4 (70.5 N). As for the tensile strength, the web with the highest tensile value is S1L6 (157.3 Pa). It is concluded that fibre feeder speed and number of stacked layer(s) can significantly affect both physical and mechanical properties of the web. Based on the given properties, it is safe to conclude that the web produced from this study can be applied for the agriculture and geotextile industries.
