Long answer type questions:
1. How are yarns made from the cotton ball?
Yarns are made up of cotton fibres: fibres twisted together or lay side by side. These fibres may be natural, manufactured, or both. Fabrics will vary greatly in design, texture, and performance.
- Staple fibres are made from short fibres, e.g. cotton, linen, wool or cut synthetic fibres.
- Filament fibres are made from the long continuous form of fibres, e.g. silk and synthetics.
- Monofilament yarns consist of a single long continuous filament.
- Multifilament yarns consist of two or more filament fibres which may or may not be twisted together.
- Micro fibres are made from very fine synthetic fibres, less than one denier in thickness.
2. What is spinning and weaving?
Ans: It is a process of converting to yarn. Yarn is used for processes such as a. weaving b. knitting etc. in the spinning process these cotton ball is converted to yarn via the following process. 1. Plucking – Cotton in ball are plucked. 2. Ginning- Cotton in ball that are plucked is divided from the seeds in this process. The seed is inside the cotton is like fruit. After separating they are packed, which are called known as bales and are transported for next process. This is the process of spinning.
Weaving – The process of arranging two sets of yarn together to make a fabric is called weaving.The big reels of yarn are called bobbins.These bobbins are used for weaving the cloth.The cloth is woven on looms.After that they bleached and dyed to give a finish.
