Hint: The acrylic fabric is a polymer of acrylonitrile. The acrylic fabric has a trade name as an ‘orlon’.This polymer is a warm and strong polymer, majorly used as the alternative for the wool.
Complete step by step answer:
The acrylic fabric is a man-made or synthetic fabric. It is made from the polymer that is polyacrylonitrile.
The polyacrylonitrile or$\text{ PAN }$ is a polymerised product of vinyl cyanide (acrylonitrile). It is obtained by the addition polymerization of acrylonitrile in the presence of peroxide catalysts.
The general reaction of the addition of monomer to give polyacrylonitrile polymer is given as follows,
Vinyl cyanide can be prepared by treating acetylene with $\text{ HCN }$ in the presence of $\text{ Ba(CN)2 }$ or $\text{CuCl}-\text{HCl}$catalyst is given as follows,
$\text{ HC}\equiv \text{CH + HCN }\xrightarrow{\text{Ba(CN}{{\text{)}}_{\text{2}}}}\text{ }{{\text{H}}_{\text{2}}}\text{C=CH}-\text{CN}$
It can be also prepared by passing the mixture of propene, ammonia, and air over a catalyst consisting of a mixture of oxide of molybdenum, cobalt, and aluminium at$\text{ 723 K }$.
$\text{ }\begin{matrix}
\text{2C}{{\text{H}}_{\text{3}}}\text{CH=C}{{\text{H}}_{\text{2}}} & + & \text{3}{{\text{O}}_{\text{2}}} & + & \text{2N}{{\text{H}}_{\text{3}}} & \xrightarrow[\text{723 K}]{\text{Oxides of Mo , Co and Al}} & \text{2C}{{\text{H}}_{\text{2}}}\text{=CH}-\text{CN} & + & \text{6}{{\text{H}}_{\text{2}}}\text{O} \\
(\text{Propene}) & {} & \text{Air} & {} & {} & {} & \text{Vinyl Chloride} & {} & {} \\
\end{matrix}\text{ }$
It is a hard, high melting substance. It is also known as the acrilon or the orlon.
The acrilon or Orlon or the Acrilan fabrics are used for making carpets.
The Orlon contains the $\text{ 85}{\scriptstyle{}^{0}/{}_{0}}\text{ }$ of the acrylonitrile. It is a warm and strong fabric.
It is used as a substitute for wool for making the blankets, sweaters, bathing suits, socks, etc.
Therefore, the assertion: Acrylic fabrics are also known as orlon and Acrilan fabrics are a correct statement. Similarly the reason: It is used in making sweaters, socks and shawls is also a correct statement. But, the given reason is not a proper justification of assertion.
We can say, Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion. So, the correct answer is “Option B”.
Note: The modacryl is modified acrylic fiber.It is prepared by the at least $\text{ 35}{\scriptstyle{}^{0}/{}_{0}}\text{ }$ to at most $\text{ 85}{\scriptstyle{}^{0}/{}_{0}}\text{ }$ of the acrylonitrile, vinylidene chloride or vinyl bromide. The modacrylic has the flame retardant or fire resistance properties. It is used in protective clothing.
