The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
Lotions, cosmetics, and other skin treatments are worn for an extended period of times as films. Long wearing films are used cosmetically on facial features for a variety of purposes, such as, to tighten the skin, to smooth out wrinkles, to moisturize the skin, and as cosmetics. A problem often encountered is the removal of the long wearing film. Films can adhere stubbornly to skin. In order to remove such films requires aggressive rubbing or a prolonged period or both prolonged and aggressive rubbing. The aggressive or prolonged rubbing can lead to irritation of the skin. Furthermore, even after prolonged or aggressive rubbing, film residues may remain on the skin. Accordingly, in an aspect of this disclosure, an article is disclosed that when used in combination with a removal formulation will assist in efficiently and gently removing films from facial features and other areas of the skin.

In an aspect of this disclosure, articles have an exterior made from microfibers. In an embodiment, a microfiber is an ultrafine filament of less than about 1 denier. In an embodiment, a microfiber is an ultrafine filament of less than about 3 denier. In an embodiment, a microfiber is an ultrafine filament of less than about 5 denier. In an embodiment, a microfiber is an ultrafine filament of less than about 10 denier. A denier is a unit defining the fineness of single fibers in terms of liner mass density, i.e., the weight of a given length of fiber. A denier equals one gram for every 9000 meters.
In an embodiment, microfibers have noncircular cross sectional shapes. In an embodiment, microfibers have a wedge or triangular cross sectional shapes. In an embodiment, microfibers with geometrical shapes are made, in an embodiment, from “splittable” microfibers. An embodiment of a splittable microfiber is represented by the diagrammatical illustration of
In an embodiment, the splittable microfibers are about 3, 5, or 10 deniers or less. In an embodiment, the splittable microfibers are carded to form a web, and then the web passes under hydroentangling jets, which split the fibers into individual wedges and entangle the fibers to give the fabric its feel and strength. As a result, the fabric contains microfibers down to 1.0 denier or less per filament.
In an embodiment, the splittable microfibers are made from a first polymer and a second soluble polymer. For example, in an embodiment, splittable microfibers are made from a polyester and co-polyester, where the polyester exists as microfiber islands in a sea of co-polyester. Then, the fibers are chemically treated to dissolve the co-polyester leaving the polyester microfibers.
In an embodiment, the splittable microfibers are made by meltblowing or spinning two or more dissimilar materials, such as polyester and polyamide, through a specialized die. Once the splittable microfiber is spun, the microfibers are processed, such as by carding, to be used as for making woven fabrics, knit fabrics, and the like. In addition, microfibers are also made into non-woven fabrics. In an embodiment, before or after carding, the microfibers are subjected to mechanical action or chemicals to cause the individual segments of the splittable microfiber to separate. The splitting of the splittable microfibers into even smaller microfibers results in a very soft fabric. In an embodiment, the split microfibers entangle with each other resulting in the very soft feel. Further, the cross sectional geometry of the split microfibers give microfibers certain advantages. In an embodiment, for example, the microfibers 100, 200 have cross sectional shapes that include sharp edges or corners. In an embodiment, these microfiber shapes enhance the removal properties of fabrics made from such microfibers. In an embodiment, an article has an exterior made from splittable microfibers. In an embodiment, an article has an exterior made from the split microfibers that have been split from a splittable microfiber.
The list of polymers explicitly recited for making microfibers are not meant to be exhaustive, but, merely are provided to give exemplary microfibers that are pertinent to this disclosure. In an embodiment, the methods and articles of this disclosure are applicable to all types of microfibers, whether synthetic or natural.
In an embodiment, film removal articles are made from microfiber fibers.
In an embodiment, the film removal articles include one or more hydrophobic materials, hydrophilic materials, lipophilic materials, and the like. For example, in an embodiment, the film removal articles include one or more hydrophilic materials capable of drawing moisture, polar formulations, skin tightening film formulations, film-forming formulations, film forming polymers, and the like from the surface of the skin. In an embodiment, the film removal articles include one or more hydrophobic materials capable of drawing film-forming formulations, skin tightening film formulations, film forming polymers, and the like from the surface of the skin.

In an aspect of this disclosure, a microfiber article wetted or soaked in a removal formulation is used to remove a film. In an embodiment, the film is a skin tightening film.
In an embodiment, the unique microfiber cross sectional geometry in combination with a removal formulation allows for an efficient yet gentile removal of skin tightening films, in comparison to cotton pads, sponges, wipes, cotton balls, and the like. Non-microfiber articles can lead to skin irritation due to prolonged or harsh rubbing on the skin. In an embodiment, the combination of a microfiber article and a film removal formulation are sold together as a unit.
Experimental Detail:
Consumers used a microfiber mitten in accordance with embodiments of the invention and a round cotton pad with a biphasic make-up remover to remove the skin tightening film after 6 hours of wear. Enough of the remover solution was deposited on the microfiber mitten or the cotton pad to saturate the fabric. Then the saturated fabric was applied to the skin tightening film and dabbed on for about 30 sec before starting to rub off the skin tightening film. The removal time was recorded, including the 30 seconds of soaking time.
Results:
The results show that a microfiber mitten wetted with the biphasic remover was more efficient in terms of time to remove the films as compared with non microfiber cotton.
While illustrative embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
