Modeling for Load Bearing Property of Nonwoven Shopping Bag
This paper measured the breaking strength of nonwoven shopping bag, which sampled from 5 kinds of fabric weight with 5 kinds of seam density and 2 types of seam methods. Based on the result of orthogonal experiment，the load bearing model is established by three-element non-linear model with two variables—fabric weight and elongate ratio of the nonwoven. Model verification shows the maximum relative error is lower than 10%. This model is proper to be applied to calculate the load bearing of 100% Polypropylene nonwoven shopping bag.
