###### Question 52 (Textile Technology & Fibre Science)

A woven fabric with areal density of 300 g/m^{2} is tested by strip tensile test method, keeping the specimen width as 5 cm and gauge length as 25 cm. If the breaking load is 900 N, the tenacity (cN/tex) of the fabric is

__**6**__.

**[Show Answer]**

write here

**Given**:

Areal density of woven fabric=300 g/m^{2}

Specimen width=5 cm = 5X10^{-2} m

Breaking load=900 N

Tenacity(cN/tex)=?**Now**,

g/m =300x5x10^{-2}

gram/meter =15 ,

i.e 1 meter have =15 gm ,

So, 1000 meter have =15*1000** Tex=15000** (Tex is mass in gm of 1000 meter length=gm/1000 meter)

**Now by formula**:

Tenacity=

Tenacity=

Tenacity=

Tenacity=

**Tenacity=6**(Answer)
