The fabric comfortable capability including heat transfer property, thermal insulating property, moisture permeability, fabric style, stiffness and flexibility, drapability, fuzzing and pilling performance, flame retardant property, etc.
The heat transfer property of fabric refers to the capacity of heat energy through the unit area in unit time. It depends on the material type, fabric structure, and air layer in fabric. The opposite of heat transfer property is thermal insulating property(thermal impedance).
The moisture permeability of fabric is the ability of vaporous water to fabric. Once the water vapor stress of fabric one side is bigger then the other side, the water vapor will penetrate fabric. The moisture permeability has close relation to the fabric material, yarn structure, fabric structure and its tightness etc.
The fabric air permeability is the ability of fabric through the air, mainly depends on the interval space between the yarn and fiber, and the shape of fiber cross section. The bigger warp-weft compactness of fabric, the tighter of fabric and the worse air permeability.
The fabric style refers to the certain appearance and tactus capacity of fabric, appearance such as color and luster, vividness, leveling property, gloss, coverage, yarn levelness and degree of finish etc. Tactus such as smooth, rough; sliding waxy, stiff and smooth; slippery, sandy; rigid, soft; fluffy, harden; thick and solid, thin; fullness, loosely; warm, cool etc.
The hand of the fabric refers to check the certain physical properties with the hand feeling, it is one of the important aspects of style. Different fabric has different hand feeling. The factors that influence fabric hand feeling are: fiber material, yarn twist, direction of twist, fabric structure and dyeing and finishing process, etc, in which the effect of fiber material is obvious. Hand feeling also relates to certain mechanical properties, for example, the pliability, extensibility and rebound resilience of fabric, etc.
The gloss of fabric refers that when light strikes the fabric, the reflected light makes the fiber produce gloss. Fiber surface is smoothly, parallel arrangement is consistent, the reflected light is stronger, then fabric luster is bright; Otherwise, fiber surface is rough, parallel arrangement is inordinate, the reflected light is diffused into different direction, then fabric luster is dark.
The stiffness and flexibility of fabric refers to the the fabric’s ability to bear the bending stress, also called flexural rigidity. Higher flexural rigidity means bigger strong of the fabric. Suitable flexural rigidity means the fabric is stiff and smooth.
The drapability of fabric is the feature of fabric having smoothness and evenness in curvature when naturally hanging. The more soft the fabric, the better drapability. The Drapability of fabric is about the stiffness and flexibility, the bigger flexural rigidity fabric means poor drapability.
Because of the fabric’s repeated rubbing in the process of wearing and washing, the surface fiber end leak out, glow many hairs, which is called “fluffing”. Once fall off not in time, they will tangle together and screw up into many granules, which is called “pilling”. The pilling of the fabric is related to shape, length, fineness and section morphology of fiber etc.
When fabric encountered sharp objects in the process of wearing or washing,sharp objects will racking out fiber or monofilament of fabric, silk ring is formed in the surface, and even be broken, then formed yarn waste shape called snag. The appearance and solidness of fabric will be affected. Knitted fabric is often laddered by snagging, destroy the organizational structure. The factors that influence or prevent loop are similar to the pilling.
