The comfort properties of apparel products contain many factors contributing to the wearer’s physical and psychological well-being while wearing them.

The principles for cold weather clothing  

• The outer layer of apparel protects against environmental factors.  Examples: wind, precipitation, mechanical abrasion, chemicals, particles, and similar hazards.

• The design of a functional multi-layer clothing system must consider low internal friction between layers, minimal bulk, and low weight, while the clothing must not interfere with body motion.  

Water and wind-resistant clothing: 

The clothing that can resist water penetration to some degree but not entirely is called water-resistant clothing. 

Typically, water-resistant clothing is also wind-resistant, which means it can protect from the wind. Many types of water- and wind-resistant clothing are available on the market.  

 To make these types of clothing, the fabric should be of low air permeability &  compactly woven, coated, or laminated.

In the case of a knitted sweater, it must be covered with other clothing made of compactly woven or laminated as it has high air permeability.  

 Cotton ventile is suitable for making raincoats.  

 Coated fabric like PU-coated nylon, neoprene-coated nylon, or PVC-coated polyester fabric could be used for making water & wind resistant clothing. But during sewing the dress, the needle holes must be sealed with water-resistant tape. Otherwise, the performance of the clothing may deteriorate by licking water molecules through needle holes. 

Breathable Garments: 

It is a particular type of garment through which water molecules, such as vapor, can easily pass from inside to outside.  

Classification: We can easily classify breathable fabric under three groups 

1. Cotton ventile:  

 Ventile is a trademark  

 the oldest type of breathable fabric  

 compactly woven fabric  

 finished fabric, not a grey fabric  

 It is made of 100% cotton using long staple fibers.  

 Provides excellent Waterproof and windproof properties and a high level of comfort.  

 Used in the finest outerwear and high-performance garments, it also has military,  medical, and workwear applications.

2. Coated fabric with micro hole:  

 It is a particular type of coated fabric  

 the coating contains fine fixes through which water in vapor can easily pass from inside to outside, such as Goretex  

 It is a waterproof, breathable membrane that is composed of stretched polytetrafluoroethylene (PTFE), commonly known as Teflan, and contains 9 billion pores per square inch  

 Used internally in medical applications, including sutures, vascular grafts, synthetic knee ligaments, and heart patches. 

 Also used for industrial purposes.

GORE-TEX fabric combines a lighter, thinner GORE-TEX membrane with fine denier performance. They are tough, especially breathable, and provide waterproof and windproof protection. GORE-TEX product has a 3-layer construction that comprises a GORE-TEX  membrane bonded to a tough outer material and an inner lining.  

3. Hydrophilic film-coated fabric:  

 Fabric is coated with hydrophilic film  

 Coating could be implemented with lamination, but there are no micro holes like Goretex  

 In the film coating, the polymer solution contains a certain isocyanate.

Sportswear 

• Fibers used for sportswear should not be hygroscopic.  

• Transport of liquid sweat.  

• Hydrophilic fiber surface.  

• Synthetic fibers such as polyester, polyamide, and polypropylene are employed for modern sportswear.  

• Hydrophilic finishes are quite often used.  

• Thermal insulation of sports textiles has to be much lower than that of leisure wear. 

• Thin and open textile constructions.

Everyday and Leisurewear 

  • Hygroscopic fibers are favorable for the buffering of vaporous sweat impulses.  
  • Cellulosic fibers such as cotton or viscose, other man-made regenerated fibers, and protein fibers such as wool can absorb a considerable amount of moisture within their molecular structure.  -Non-hygroscopic synthetic fibers like polyester, polyamide, and polypropylene are less comfortable for use as they cannot absorb moisture within their molecular structure.  
  • The inner surface of an apparel worn next to the skin should be somewhat hairy.  
  • In the case of filament, textured yarns are preferable.  
  • The thickness and porosity of apparel strongly affect its water-vapor diffusion or breathability.  
  • High water-vapour permeability is preferable in thicker materials.  
  • Loosely fitting.  
  • Elastic textiles.
