Tactile comfort

Cotton is generally called the King of fibres and has a wide variety of applications in general apparel and technical textiles. In apparel, cotton fibre is used to produce shirts, T-shirts, inner wear, trousers, jeans, etc. In most of the apparel products, cotton fibres are used alone or in blends with other fibres such as polyester, viscose, etc. In apparel purposes, cotton fibre is preferred because of its higher thermal and tactile comfort, which is suitable for a range of weather conditions. 

Clothing comfort provides human comfort including tactile comfort and thermal comfort. 

Scientific evidence shows that the advances made in diaper technology over the past 15 years have produced real benefits in skin care, dryness, and leakage problems. The engineering of improved levels of theimophysical and tactile comfort in wearable hygiene materials is a further area of fundamental research. In terms of product developments, we are likely to see increased levels of absorbency performance and the use of thinner materials, resulting in higher levels of comfort as well as discretion (Attesby, 2007). 

Especially for clothing, tactile properties such as stretch, shear, and handle are quite relevant. The tactile comfort is related to mechanical interaction between the clothing material and the human body and is an intrinsic and essential performance requirement in clothing. Fabric handle is concerned with the feeling of the material and so depends upon the sense of touch for a subjective evaluation of an expert (Siilar and Okur, 2008). 

Physically or chemically modifying the surface of PET fiber is another route to diversified products. Hydrophilicity, moisture absorption, moisture transport, soil release, color depth, tactile aesthetics, and comfort all can be affected by surface modification. Examples iaclude coatiag the surface with multiple hydroxyl groups (40), creatiag surface pores and cavities by adding a gas or gas-forming additive to the polymer melt (41), roughening the surface... 

The properties of textile fibers can be divided into three categories geometric, physical, and chemical, which can be measured with available methods (15—17). Perceived values such as tactile aesthetics, style appearance of apparel fabrics, comfort of hosiery, as weU as color, luster, and plushness of carpets are difficult to quantify and are not always associated with the properties of the fiber, but rather with the method of fabric constmction and finishing. 

To predict the comfort of a material, a combination of hand evaluation, eg, using the Kawabata system, as well as deterrnination of the heat and moisture transport properties, is necessary. Often, these values are correlated with a sensory evaluation of the tactile qualities of the material by a human subject panel. A thorough discussion of the many physical and psychological factors affecting comfort is available (134,135). 

We are all aware of the importance of tactile stimulation or touch. Babies and young anjmals do not thrive unless cuddled by their mothers, and individuals so deprived often go on to develop behavioural problems in adult life. When something hurts we instinctively rub it better, and the comforting hug directly conveys sympathy in times of crisis. 

I navigated through various archetypal realms of the collective human subconscious as it,manifested as complete realities. Reality felt as if it were made of flowing tactile emotions. When I got up to stand, I was surprised by an enormous weight on my shoulders, like I was lifting the entire city as I stood. Finding my balance, the weight became comfortably a part of my body. 

MDMA results in a flooding of the brain with 5-HT, as well as the release of synaptic norepinephrine and dopamine, and brings about feelings of well being, comfort, tactile sensitivity, and friendly emotions. 

A114Rest is a European-funded project focussing on improving tactile and thermal comfort in rest systems to promote a deeper, more restorative sleep. In the project s framework textile sensors embedded in a mattress were developed to monitor sleeping quality by measuring body movement and room temperature. This section summarises the results on the sensor systems (A114Rest, 2011). 

Tactile or neuro-physiological comfort of clothing is the mechanical sensations, which a textile causes at direct contact with the skin (Bartels, 2005) and depends on fabric tactile properties, skin properties, environmental conditions, activity level and garment fit (Kilinc-Balci, 2011). 

Rossi S provided an extensive review of methods to characterise clothing comfort and discussed the thermal and tactile properties of flame retardant garments, with special attention paid to the problem of sweat accumulation in the garments and its influence on thermal protection. Rossi also outlined factors influencing thermal comfort and discussed the protection/comfort contradiction as well as test methods for heat and moisture transfer.

Any hand protection product will require a compromise between comfort, protection and tactile sensitivity. An emergency medical technician, for example, cannot reasonably expect a glove to protect him from broken glass and debris at the scene of an accident while also enabhng him to take a patienf s pulse. Hand protection by definition places a barrier between skin and the outside world, and considerations of dexterity and tactile sensitivity must be part of any solution. 

Tactile sensation is an important cue for us to find a subtle difference in handling objects. For a robotic telemanipulation surgery, tactile displays, which produce virtual cutaneous sensation on human hands, provide haptic feedback to the operators for finding diseases carefully and manipulating tools dexterously. For virtual reahty apphcations in medicine, such as rehabilitation and psychotherapy, a tactile display can also contribute to human emotional responses because tactile sensation is highly related to both our comfort and wonder. Many researchers have developed tactile displays and haptic interfaces, as reported by Benali-Khoudja [1] and Hayward [2]. However, it is difficult for conventional tactile displays to synthesize rich and complex tactile sensation arbitrarily.
