Comfort properties

The guarded hot-plate method can be modified to perform dry and wet heat transfer testing (sweating skin model). Some plates contain simulated sweat glands and use a pumping mechanism to deUver water to the plate surface. Thermal comfort properties that can be deterrnined from this test are do, permeabihty index (/ ), and comfort limits. PermeabiUty index indicates moisture—heat permeabiUty through the fabric on a scale of 0 (completely impermeable) to 1 (completely permeable). This parameter indicates the effect of skin moisture on heat loss. Comfort limits are the predicted metaboHc activity levels that may be sustained while maintaining body thermal comfort in the test environment. 

Improved Comfort Properties. Wear comfort generally means cotton-like properties, The ability lo absorb moisture from the skin and ihe softness of cotton fabrics are considered to be the two key properties for comfort. The extremely line denier of cotton fibers accounts for its softness. Both properties can be achieved in acrylic fibers. Improved moisture retention can be achieved by incorporating hydrophilic comonomers that decrease ultimate fiher density, by modifying the fiber spinning process, ur by using after-treatments such as modified finishes.

The main property of the outer shell is to provide a protection against the outside weather conditions, mainly rain, snow and wind. In order to avoid excessive sweat accumulation, the outer layer should allow moisture transfer from the body to the environment. Such waterproof, windproof and breathable fabrics (WBF—mainly membranes and coatings) have been on the market for more than 30 years. The waterproof properties and, at the same time, the water vapour transfer are either achieved with a micro-porous or a hydrophilic structure, or a combination of both technologies (bi-component WBF). Waterproofness and breathability are contradictory requirements and, therefore, a compromise has to be found between protection and comfort properties. This compromise is usually achieved by adapting the porosity and thickness of such WBF layers. 

Cotton fabrics have long been considered a standard by which textile comfort properties are measured. Although many properties contribute to wear comfort [404], it is believed that the two dominant properties inherent to cotton are the ability to absorb moisture from the skin and softness. The second property is the result of the extremely fine denier of cotton fibers. Both properties can be achieved in acrylic fibers. However, fine-denier acrylics are achieved at the cost of reduced spinning productivity. 

The chemistry of the Proban and Pyrovatex processes has been presented elsewhere (Hall, 2000). Research on the durability of FR treated cotton has been performed by Chen et al. (2012), who made comparisons among Proban and Pyrovatex FRs. An increase in damaged length as in an afterglow was noticed on all treated fabrics after 15 cycles of domestic washing. No considerable effect was detected on the comfort properties (e.g., air and vapor permeability).

The activated carbon granules were coated in substrates (e.g., polyurethane foam and non-woven pads) for use as an interliner in the clothing system however, the coated polyurethane foam usually has low air and water vapour permeabihty, and it is reported that needle-punched fabrics coated with activated carbon have better thermal comfort properties. The coated activated carbon material is combined with other textile materials in permeable CPC to provide two main functions ...
