###### Question 48 (Textile Engineering & Fibre Science)

Consider the following data for a synthetic fibre.

Density of amorphous region as 1.33 g/cm^{3}, density of crystalline region as 1.45 g/cm3, density of fibre as 1.36 g/cm^{3} and diameter of the fibre as 14 micron.

Denier of the fibre is approximately

(A) | 1 |

(B) | 2 |

(C) | 3 |

(D) | 4 |

**[Show Answer]**

Given in the question-

Density of amorphous region()=1.33 g/cm3

Density of crystalline region()=1.45 g/cm3

Density of fibre()=1.36 g/cm3

Diameter of the fibre(d)=14 micron

As we know the definition of denier-

Weight of 9000 meter length .

so that denier is the mass.

Mass=Volume x density

Where d in cm

Denier=1.88
