Water Absorbency of Jute—Polypropylene Blended Needle-punched Nonwoven

Abstract

The effect of fabric weight, needling density, and blend proportion of jute and polypropylene fibers on water absorbency, fabric thickness, and fabric density has been studied. Box and Behnken experimental design has been used for preparation of needle-punched nonwoven fabric samples. Cluster analysis has been used to study the grouping behavior of the variables. Water absorbency increases with the increase in jute content. Water absorbency decreases with the increase in fabric weight and needling density. Highest water absorbency (720%) of the fabric can be obtained at 60% jute content level with lower needling density and lower fabric weight. The fabric thickness increases with the increase in jute content. At higher level of jute content, with the increase in needling density, the fabric thickness shows decrease in trend. At higher level of fabric weight and higher needling density, with the increase in jute content, the fabric thickness shows a decrease in trend. Maximum fabric density can be obtained at higher fabric weight (450 g/m 2 ), higher jute content (60%) and higher needling density (350 punches/cm 2 ) levels. The influence of fabric weight, needling density, and blend proportion of polypropylene and jute as independent variables on the cluster of fabric thickness and water absorbency is very high as evidence from the Euclidean distances.

Compression creep behaviour of jute-polypropylene blended needle-punched nonwoven

“…Each factor was run at three levels so that the experiment was a 3 3 factorial design with two replicates as per the Box Behnken design of experiment. 14 The samples were prepared after randomisation according to a random number table and the sequence of sample production comprised the process variables given at serial numbers 2,4,9,11,6,5,15,14,1,12,7,8,3,10,13. The reasons for randomisation were an effective statistical analysis and the validity of the inference drawn.…”

“…The model was used to obtain theoretical creep curves for different nonwoven fabrics and these curves were compared with experimental creep curves. Compression properties of needlepunched nonwoven fabrics have been studied extensively [7][8][9][10][11] and have also been predicted by artificial neural network models. 12,13 Research also reveals the compression properties and parameters influencing such properties under wet conditions.…”

Modelling of Needle-Punched Nonwoven Fabric Properties Using Artificial Neural Network

“…The initial thickness (Debnath & Madhusoothanan, 2010a), compression, thickness loss and compression resilience were calculated from the compression and decompression curves. For measuring these properties, a thickness tester was used (Subramaniam et al, 1990).…”

Effect of substrate geometry on oil sorption capacity of raw and chemically modified jute fibre

“…On absorption of moisture, these fibres swell, ultimately increasing the thickness of the fibre [10]. Like other natural fibres, jute fibres degrade in moist conditions and thus can be used in geo-textile applications by providing reinforcement for a limited period of time.…”

“…Generally, the webs of jute fibres are manufactured by using carding technology. The nonwovens prepared from jute fibres are generally bonded by using needle-punching technology, thermal-bonding with the help of binder fibres and chemical-bonding are also employed (Debnath et al, 2011) [13]. Key characteristics include silky lustre, low extensibility, high friction, easy biodegradability and environment friendliness, high moisture absorption and thermal and electrical insulation.…”
