Long Answer Questions


Question 24:  A cotton shirt, before it reaches you, completes a long journey. Elaborate this journey starting from cotton bolls.  

Solution 24:   Cotton is made from the natural fibers of cotton plants, which are from the genus Gossypium. It is a soft, fluffy staple fiber that grows in a boll.

The journey of making a cotton shirt is completed through the following processes-

  1. Ginning- In this process, cotton is picked up from cotton boll in the field of cotton plant by hands. Then fibers are separated from the seeds by combing.
  2. Spinning- In this process, the fibres are take out from large cotton wool and twisted. These twisted fibers form a long and twisted thread called yarn.
  3. Weaving- In this process, the two sets of yarns are arranged together to make a fabric. This is done by looms. Loom is a tool used for weaving yarn.
  4. Sewing- In this process, this cotton fabric is stitched into a shirt by needle on sewing machine and we get the cotton shirt.

 

Question 25:  Describe the two main processes of making fabric from yarn. 

Solution 25:   The two main processes of making fabric from yarn are weaving and knitting. These are as follows:

Weaving- Weaving is a process in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. The way the warp and filling threads interlace with each other is called the weave. This is done by looms. Looms is a tool used for weaving yarn. The looms are either hand operated or power operated.

Knitting- Knitting is a process in which a single yarn used to make a fabric.

It is a method by which yarn is manipulated to create a textile or fabric; it is used in many types of garments. Knitting may be done by hand or by machine. Knitting creates stitches: loops of yarn in a row, either flat or in the round (tubular).
