Key Factors of Clothing Comfort

There is some difference between conventional garments and special garments or technical garments. Now a days we are producing technical garments very carefully such as water and wind resistant cloth, breathable cloth. Comfort is one of the principle criteria of technical garments. It is not easy to explain about comfort since it is a complex and interdependent combination of physical, psychological and sensorial perceptions and highly depends of subjective evaluation of the individuals. But there are some key factors to become clothing comfort. In this article I will discuss about it.

Necessity of Clothing:
Clothing is one of the basic necessities of human being. It serves various and diverse purposes. Selection of cloth is dependent on desires and requirements of an individual. Principle necessities of clothing are:
  1. To protect the adverse situation
  2. To lead the civilized life
  3. To look attractive
  4. To protect body from unusual situation
  5. To feel comfort
Constant body core temperature:
The main purpose of clothing is to maintain constant body temperature. Generally skin temperature 33 Celsius and core temperature 37 Celsius.

Process of losing temperature from human body:
  1. Conduction
  2. Convection
  3. Radiation
  4. Perspiration and respiration
Key parameters or factors of clothing comfort:
Depending parameter on which clothing comfort depend on:
  1. Fiber type
  2. Fabric construction
  3. Thickness
  4. Density
1. Fiber type:
This is important parameter for clothing comfort. More compact area between skin and fiber in case of cotton fiber remains straight in fabric. Experimentally shows that heat transfer through fiber is more than air. That’s why more heat passes through cotton from body. So cotton fabrics feel cool in warm season. But in case of wool and blended of wool fiber, there is crimp so it cannot be straight in fabric. As a result contact area between fiber and body skin is less. Due to less heat conductivity of air less amount of heat is lost from body so we feel warm in cool weather example: wool made fabric. In case of VILOFT (Blended of viscose & polyester) fiber, fabric is hairy. Due to this hairiness there is more air space. So heat loss through clothing is poor here. So it is also felt warm when worn.

2. Fabric construction:
Normally we consider two types of fabrics such as woven and knit. In case of woven fabrics there is less still air & more fiber so heat transfer is more than knit fabric because in case of knit there is more still air.

3. Density:
For high density fabric, heat loss through fabric is more and for low density heat loss is less.

4. Thickness:
Thickness is important parameter for heat loss. For more thickness fabric heat loss is less and vice versa.
