BACKGROUND OF THE INVENTION [0001] The present invention relates generally to user adjustable or expandable materials for use in protective apparel or garments. More specifically, a user adjustable or expandable material for use in an adjustable protective garment is disclosed. A garment using such a material will be capable of providing some protection for an individual in a hazardous environment while permitting easy size adjustability. Protective apparel or garments, such as coveralls and gowns, designed to provide barrier protection to a wearer are well known in the art. Such protective garments are used in situations where isolation of a wearer from a particular environment is desirable, or it is desirable to inhibit or retard the passage of hazardous liquids and biological contaminates through the garment to the wearer. [0002] For example, in the medical and health-care industry, particularly with surgical procedures, a primary concern is isolation of the medical practitioner from patient fluids such as blood, saliva, perspiration, etc. Protective garments rely on the barrier properties of the fabrics used in the garments, and on the construction and design of the garment. Openings or seams in the garments may be unsatisfactory, especially if the seams or openings are located in positions where they may be subjected to stress and/or direct contact with the hazardous substances. [0003] Originally, surgical gowns were made of linen, the gowns being sterilized prior to use in the operating room. Linen gowns were not capable of preventing "strikethrough" of various liquids encountered during surgical procedures. As a result, the wearer's clothes came into contact with blood and the like, and a path was established for the transmission of bacteria to and from the wearer of the gown. Additionally, linen gowns, due to their high cost, had to be used a number of times, thus necessitating laundering and sterilization between successive uses. [0004] In an attempt to reduce strike-through of liquids and to eliminate the need for repeated laundering and sterilization, disposable gowns were made from fluid repellent nonwoven fabrics. These gowns reduced liquid strike-through for a limited time. However, due to the generally inextensible nature of these nonwoven fabric constructions typically they tend to have less ability to conform to the body than the previously used linens or knits. In order to accommodate for a range of body shapes and sizes, the gown is designed to be loose fitting especially in the chest region, sleeve length, and gown length. Making the gown loose fitting generally minimizes the possibility that the gown may otherwise be undesirably too tight in some area or areas. However, this creates the very obvious problem that the gown will be too big for some wearers. By making the gown oversize a wearer having body dimensions smaller than the maximum size contemplated by the gown is subject to areas or regions of the gown or sleeve that hang or are caused to hang loosely. This phenomenon is known as "blousing". Unfortunately blousing often occurs in or at regions which may be undesirable for the intended use of the gown. Such areas often include the chest region, sleeve area, and the overall length of the gown itself. [0005] Moreover, many health care facilities purchase only the extra large size version of surgical gowns in order to minimize the volume of different inventory they must maintain on site. In order to fit these gowns to an individual who may be smaller than that intended by the gown size, the typical wearer resorts to taping sections of the gown together to minimize blousing, for example, in the sleeve area or chest region as well as cutting portions of the gown away so as to shorten the overall length of the gown or shorten the sleeve length. [0006] Thus, a need exists for an improvement in materials which may provide some degree of adjustability to an end user that may be incorporated into user worn protective apparel or garments. Such a material would be capable of being easily incorporated into the protective garment and would also be economically cost effective to implement and practice. SUMMARY OF THE INVENTION [0007] Objects and advantages of the invention will be set forth in the following description, or may be obvious from the description, or may be learned through practice of the invention. [0008] The present invention relates to a material that may be found useful in making a unique configuration of a protective garment, particularly a surgical gown, wherein regions of extensible material are selectively provided in the garment to provide for adjustability to accommodate various size wearers. The areas or regions containing extensible materials may be incorporated into the garment by the addition of a dedicated material having characteristics described herein or alternatively may be formed from the substrate material of the garment itself. In any event, the regions of extensibility are typically surrounded by the remaining material of which the garment is made, generally a nonextensible material and, thus, the regions of extensibility may be thought of as "islands" of extensible material strategically located throughout the gown. [0009] It should be appreciated that, although the present invention has particular usefulness as a material capable of incorporation into a surgical gown, the invention is not limited in scope to surgical gowns or to the medical industry. The material according to the present invention has wide application and can be used in any instance wherein a user adjustable material is desirable in such garments as protective coveralls, gowns, robes, etc. As such, all such uses and garments are contemplated within the scope of the invention. [0010] The garment, in form according to the invention may be a surgical gown having a conventional body configuration. That is, the garment may have a closed front portion made from a first panel of material and an open back portion defined by back panels that are attached to the first panel of material alongside the seams of the garment. In an alternate embodiment, the garment may have front and back portions formed from a single piece of material. As discussed in greater depth, the style and configuration of the garments of the present invention are not intended to be considered a limiting factor. [0011] In an embodiment of the invention, a protective garment is provided having a garment body. The garment may be, for example, a surgical gown, a protective coverall, etc. Moreover, in one particular embodiment an expandable garment is provided. The expandable garment may have a garment body with two sleeves attached. The garment body and sleeves may be formed of a nonwoven fabric having a first fabric surface and a second fabric surface which is opposite the first fabric surface. A section of the fabric defines at least one region gathered into a plurality of successive pleats. Each pleat is made of an overlap in the fabric such that a portion of the first fabric surface is disposed adjacent to another portion of the first fabric surface. These two adjacent surfaces are affixed to one another. The entire region is selectively extensible by application of a tensile force to the region which causes the two surfaces to at least partially detach thus enabling the pleat to at least partially unfold. [0012] In a further embodiment, it may be desirable to place a plurality of such regions upon sections of the garment. Each region may be adapted to be independently lengthened to accommodate different size individuals. For example, the regions may be adapted to affect overall garment length, affect overall sleeve length, and to affect garment width. A releasable adhesive may be disposed upon at least one portion of the first fabric surface for affixing the surfaces together. Additionally, a releasable adhesive may also disposed upon at least one portion of the second fabric surface for affixing adjacent pleats to one another. Such a garment may prove useful as medical apparel, surgical gowns, shirts, and/or coveralls. [0013] In another embodiment, an extensible material for use in a garment is provided. Such a material may be configured as a fabric having a length, a first surface, and an opposing second surface. The fabric may contain at least one pleat transverse to the length. The pleat may be made by overlapping the fabric such that a first portion of the first surface is disposed adjacent to a second portion of the first surface and the first and second portions are removably affixed to one another until freed by application of a tensile force directed along the fabric length. Adjacent pleats may be removably affixed to one another until freed by application of the tensile force directed along the fabric length. The required tensile force may be applied by a wearer pulling on the material. The adhesive may be applied so that application of the tensile force results in an incremental release of the affixed portions or application of the tensile force may result in a smooth release of the affixed portions. [0014] Embodiments of the protective garment according to the invention are described below in greater detail with reference to the appended figures.
