A shirting cotton cloth is made from the following particulars :

Warp crimp, C_{1} = 10%

Warp yarn dia, d_{1} = 0.01627 cm

(T_{2}/T_{1})^{1/2} = 0.8

K_{1} = 11.3

K_{2} = 9.1

Fabric area density = 91.15 g/m^{2}

where T is yarn tex and K is the cover factor is SI unit denoted by (threads per cm)(tex)^{1/2} X 10^{-1} .

###### Question 50 (Textile Engineering & Fibre Science)

Thickness of the fabric will be

(A) | 0.003 cm |

(B) | 0.033 cm |

(C) | 0.025 cm |

(D) | 0.005 cm |

**[Show Answer]**

Given in the question-

Warp crimp, C1 = 10%

Warp yarn dia, d1 = 0.01627 cm

(T2/T1)1/2 = 0.8

K1 = 11.3

K2 = 9.1

Fabric area density = 91.15 g/m2

Firstly we will calculate tex of warp yarn-

By formula-

By doing square both side-

Tex

Now, given-

By putting value of T1

Square both side-

tex

cover factor(K)=(threads per cm)(tex)1/2 X 10-1 .

So that,

Where h is the crimp height and d is the diameter of the yarn.

cm
