Question

Discussions: Please kindly answer the following child questions AS IN DETAILS AS POSSIBLE (Child questions are total 4, which is well-aligned with Chegg's Policy).

1) Draw schematics of the fiber chains before and after the ironing. And then, discuss whether the ironing temperatures of clothes are dependent on the materials (cotton, polyester/nylon, silk, wool).

2) Discuss the role of water in the degree of wrinkles or in the ironing temperatures.

3) Discuss the effect of water on the fiber molecules. Specifically, discuss the effect of water on the ironing temperature. Discuss the effect of water on the degree of wrinkle when you shake the clothes (by comparing when you shake the cloth without using water).

4) Draw the effect of water on the motions of polymer chains (including chewing gum).

Answer 1

yes, different types of clothes requires different heating temperature.

For example,

Cotton :

High temperature, pre moistened and steam is required.

Polystyer:

Pre moistened and medium heating.

Nylon:

Dry iron heating with no water spray.

Wool:

Low heating on wrong side of cloth with cloth pressing using another cloth.

2) ans.

When the clothes are wet, the hydrogen bonds on molecules comes closer and misaligne. Whereas when we iron the clothes due to heat the molecules losses the water and the hydrogen bond breaks and they becomes tighten and aligned.

The more you heat, the easily bond breaks and easily clothes becomes aligned.
