Soft feel

Hair conditioning can be associated with almost any hair product sold in the marketplace because they all claim some benefit to the hair when used. Thus the term hair conditioner can be appHed to such products as rinses, hair dressings, setting lotions, and hair sprays. Conditioners are used to provide different effects to the hair primarily ease of combing, sheen, and soft feel. 

The method used to apply and dry a fixative affects the degree of stiffness and hold it imparts to the hairstyle. If appHed and then manipulated with a comb, bmsh, or fingers as the polymer forms its film, the adhesive bonds between the hair are broken, the film coating the hair is broken, and the end result is a soft feel with Htde set retention. If the fixative is allowed to dry undisturbed, then the result is a firmer feel and better hold. 

Man-Made Leathers. These materials contain a nonwoven fabric which is impregnated with a polyurethane to improve fiexibiHty, processibiHty, and conformabiHty (Fig. 9). Advanced man-made leathers contain microfibers as fine as 0.03 tex (0.3 den) or less to imitate coUagen fiber bundles, thereby attaining the soft feel and appearance essential for soft leather use. Polyurethane in the substrate is usually provided with porous stmcture by poromeric technology. The coating layer is also porous in the two-layer type man-made leathers (5—10). 

Abbreviations of prominent use properties of the various classes of commercial surfactants are shown in Table 1. Antimicrobial activity includes germicidal, bactericidal, and bacteriostatic effects emolliency describes lubrication or a soft feel imparted to skin by surfactants a hair conditioner is a substantive surfactant appHed from aqueous solution to impart a lubricating or antistatic effect and opacifters are used to thicken hand-dishwashing products and cosmetic preparations to convey an appearance of high concentration and to retard solvent drainage from foam. 

The use of enzymes is a common approach to reducing energy consumption during manufacture, and they are often found in unlikely products. Providing jeans with soft feel and attractive colouration of the stonewashed look is an expensive business. 

Bonds in the same plane are very strong, but attractions between the layers are much weaker. Because of this weak bonding between the layers, the layers can slide over each other. This makes graphite a good lubricant, and gives it a soft feel. It conducts electricity. 

These fibres have a soft feel, an excellent abrasion resistance, excellent energy absorption behaviour and a moderate level of cut protection. 

In recent years, the use of cotton in garments has witnessed a revival. The higher comfort level of cotton fabric as compared to man-made fibers tilts the balance of customer favor towards cotton as the basic fiber in clothes. After many wash cycles, however, both the appearance and the soft feel of the cotton fabric are lost the surface appears bland and the fabric touch has turned rough. This roughness stems at least in part from loose ends of cotton fibers which have separated from the bulk fabric and stick out on the surface. To combat this phenomenon termed pilling, cellulases have been developed to preserve both the appearance and feel of cotton fabric during washing. 

Fibers with a fineness of less than 1 dtex are called micro fibers. Articles made of microfibers are characterized by a low weight, soft feel, weather resistance, and... 

Use is made of integral skin foams. They are flexible urethane foams with a high density skin. They are used in applications such as steering wheels, arm rests, and protective covers that must combine a tough surface and a soft feel. 

In terms of skin irritation and user compliance, elastic backing is more desirable. However, elastic backing materials such as polyurethane and EVA copolymer cannot be used as themselves due to their drug-permeable nature. Recently, PET/EVA laminate and PET/non-woven fabrics laminate backings are becoming popular for systemic TDS. These laminated materials are expected to add a soft feeling to the hard backing layer. 

Blends contain ultra-high-viscosity fluids in low-viscosity fluids to improve spreadability, soft feel, and substantivity. 

Cationic surfactants appeared on the market in 1933. They were originally used as dye leveling agents in the textile industry, to improve the water fastness of direct and acid dyes on cellulose [1-3]. Some of the first cationic actives were synthesized by Ciba (Switzerland) and commercialized as Sapamines [1], Very quickly, the soft feel delivered by long-chain derivatives was noticed and exploited to restore the fabric finish. 

Soy fibers were white to tan in color and had warm soft feel, natural crimp, and high resilience (Hartsuch, 1950). Soy protein fibers had more elongation and 80% of wool s dry strength (Boyer, 1940). These textile efforts, however, were not as successful as those made with casein fibers and failed, largely because soy protein fibers had... 

Thixotropic air-drying and oven-drying alkyd resins with low oil contents are used as binders for one-coat industrial paints with a high dry-film thickness of 50-75 pm. In special-effect paints (e.g., hammer finishes, soft-feel coatings, textured finishes) they facilitate fixation of the desired effect and prevent smudging. 

Using spandex as the center core, and different types of outer yams, different types of elastomeric yams can be created offering soft feeling and multiple functionalities. The spandex is given complete protection by the outside fibers, which lengthens fabric life.
