QUESTION AND ANSWERS.

LECTURE 18. 

Q: WHAT ARE THE DIFFERENCES BETWEEN THE FLEECE OF ANGORA GOAT AND CAMEL?

A: THE WORD FLEECE  ITSELF REFERS TO A VERY SOFT HAIR FLEECE OF ANGORA GOAT IS VERY SOFT COMPARING TO CAMEL FLEECE. 

ACTUALLY, THE  CAMEL HAS COARSE HAIR ON ITS BODY. THE THINGS MADE UP OF FLEECE OF CAMEL ARE  SHAWLS AND SWEATERS.

BUT THE THINGS MADE UP OF THE FLEECE OF ANGORA GOAT ARE SCARVES AND OTHER CHILD WEARS.

WOOLLEN FABRIC

Q: WHAT IS THE DIFFERENCE BETWEEN KNITTING AND WEAVING?

A: BOTH THE PROCESSES ARE FOR MAKING FABRIC ONLY. THE MAIN DIFFERENCE IS KNITTING: KNITTING CAN BE DONE BY HAND USING TWO NEEDLES. USING THESE TWO NEEDLES KNOTS ARE MADE BY RINGS AND LOOPS. MOSTLY THE KNITTING IS DONE MANUALLY ONLY.

WEAVING: WEAVING CAN BE DONE BY BOTH MANUALLY AND AUTOMATICALLY. MANUALLY HUMAN INVOLVEMENT IS THERE. THE FABRICS WHICH ARE MADE BY MANUALLY ARE CALLED AS HANDLOOMS. BUT WHEREAS AUTOMATICALLY, MACHINE INVOLVEMENT IS THERE. SO THE FABRICS WHICH ARE MADE BY MACHINES ARE CALLED AS POWER LOOMS.
