TENACITY OF TEXTILE FIBERS AND STRENGTH OF PRODUCTS

TENACITY OF TEXTILE FIBERS AND STRENGTH OF PRODUCTS

          Tenacity, the term used for strength of the textile fibers in the form of hair is directly influenced by its morphology. If highly oriented polymer chain regions in fiber structure are high, then tenacity of that fiber will be high.

          Yarn strength in terms of Tensile strength also influenced by fiber Tenacity but with additional factors like twist per inch, level of yarn ply, cohesiveness, etc,. in yarn.

          Fabric strength influenced by fiber Tenacity but with additional factors like fabric cover,nwet process condition, fabric finishes, coatings, etc,.

          Garment strength also influenced by fiber Tenacity but with additional factors like fabric strength as said above, stitch per inch, size of the fabric cut, garment finish or treatments, etc,..

          On the other hand, if tenacity of fiber is badly affected by treatments involved with chemicals involvement, subjected to temperature variations, etc, may reduce the strength of the product.

           The Pass Test report depends on end customer requirements and acceptance.

Examples of Tenacity of few popular fibers are given below:

(Tenacity Expressed in Grams per Denier)

Raw Cotton: 3.0 to 5.0

Silk: 2.4 to 5.1

Wool: 1.0 to 1.7

Acrylic: 2.0 to 3.6

Polyester (Regular): 2.5 to 6.3

Polyester (High Tenacity): 6.0 to 9.5

Nylon 6 (Regular): 3.5 to 9.0

Nylon 6 (High Tenacity): 7.7 to 9.5

Nylon 6,6 (Regular): 4.3 to 9.0

Nylon 6,6 (High Tenacity): 5.7 to 9.5

Etc,..

Tenacity of the individual fibers can also be expressed in terms of Grams per Tex.
