Mechanical properties of bamboo/cotton fabric as affected by bamboo fiber content and weft density

The mechanical properties of fifteen bamboo /cotton fabrics with different specifications were tested,such as tensile strength at break,breaking elongation,tearing strength and fastness to abrasion,etc,and the effects of bamboo fiber content and weft density on the mechanical properties of the fabrics were researched.The results showed that with the increase of bamboo fiber content,the total tensile strength at break(warpwise + weftwise) declined,the weftwise breaking elongation increased,and the warpwise breaking elongation firstly increased and then declined.Weftwise tearing strength firstly declined and then increased,and warpwise tearing strength exhibited little changed.Fabric weight loss accelerated,fastness to abrasion deteriorated.When bamboo fiber content was 30%,the fastness to abrasion was the best.When bamboo fiber content was up to 70%,the tensile strength at break,breaking elongation,tearing strength and fastness to abrasion became the worst,and this should be avoided in actual production.When warp density remained fixed,increasing weft density increased tensile strength at break,breaking elongation,and fastness to abrasion,but reduced tearing strength.
