1. Field of the Invention
The present invention relates to garments and, more specifically, to a garment that has a portion subjected to high levels of perspiration.
2. Description of the Prior Art
Undergarments are worn next to a wearer's skin as an interface between the skin and the wearer's outer garments. There is a wide range of undergarments, such as panties, undershorts and undershirts. Undergarments are worn for a variety of reasons. For example, certain undergarments (such as brassieres and girdles) provide shaping and support for the user. Other undergarments, such as panties and undershirts, are worn for personal hygiene by absorbing perspiration and other materials from the skin and reducing the rate at which they are allowed to reach the outer garments.
Depending on the nature of an undergarment, it can be made from one of several different materials. For example, less stylish undergarments used for absorbing perspiration and heat retention are frequently made of cotton. Undergarments in which appearance is important are often made of synthetic materials and silks.
It is known to line certain stylish undergarments made of synthetic fabrics, such as panties, with a cotton liner. While the outward appearance is of panty has a desired color, sheen and texture, the cotton liner absorbs perspiration. This is done for added comfort and odor reduction.
Since certain area of the body, such as the crotch and the armpits, tend to be relatively warm and perspire at a relatively high rate, bacteria and other microbes tend to grow at a relatively high rate in these areas. Such microbes often generate unpleasant odors and can cause skin irritation. Wearing of cotton undergarments, or undergarments with cotton liners, can reduce the amount of perspiration adjacent to the skin in these areas. However, cotton tends to become saturated quickly and does no inhibit growth of microbes.
Bamboo fabric is a natural textile made from bamboo fibers. Bamboo is a fast growing grass that is highly sustainable. Fabric made from bamboo fibers has excellent wicking properties and may absorb more water than cotton fabric prior to saturation. Bamboo fibers also contain a substance referred to as “bamboo kunh,” which has anti-microbial properties. Also, bamboo fabric has a high carbon content and is quite porous so as to have a high surface area. The carbon in bamboo fabric may also bind with organic molecules, thereby interrupting microbe growth.
The bamboo kunh stays in the bamboo fabric even after multiple washings. Thus, clothing made of bamboo fabric has the ability to kill odor causing microbes (such as bacteria, yeast and fungi) that live on human skin, without requiring treatment with harmful chemicals. This feature results in the wearer producing less unpleasant odors for a given perspiration level.
Many fabrics also induce allergies in the wearer, especially in high perspiration zones in which the skin already tends to be tender. Bamboo fabric, on the other hand, is also smooth and hypoallergenic. Thus, even users with sensitive skin can wear bamboo fabric without experiencing allergic reactions.
Unfortunately, because of the nature of bamboo fibers, it is difficult to make bamboo fabrics that are shear enough for certain undergarment applications. Also, certain undergarment styles require a type of sheen that is not readily achieved in untreated bamboo fabric.
Therefore, there is a need for undergarments that have a desired outward appearance, but that absorb high amounts of perspiration and inhibit growth of microbes.
The disadvantages of the prior art are overcome by the present invention which, in one aspect, is a lower body undergarment having an inside and an outside. The undergarment includes a non-bamboo fabric panty including a crotch member. A bamboo fabric member is affixed to the crotch member so as to line the a portion of the crotch member.
In another aspect, the invention is a garment that includes a non-bamboo fabric body portion that has at least one high perspiration area. A bamboo kunh-enriched fabric member is affixed to the high perspiration area.
In yet another aspect, the invention is a method of making a lower undergarment. A piece of non-bamboo fabric is cut so as to form an unassembled panty having a crotch member. A piece of bamboo fabric is cut so as to correspond in shape to the crotch member. The piece of bamboo fabric is affixed to the crotch member. The unassembled panty is sewn so as to form a completed panty.
These and other aspects of the invention will become apparent from the following description of the preferred embodiments taken in conjunction with the following drawings. As would be obvious to one skilled in the art, many variations and modifications of the invention may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.”
One embodiment of the invention is an undergarment that includes a body portion (e.g., a panty or an undershirt) in which a liner made of bamboo fabric is affixed to high perspiration areas (e.g., the crotch or armpits) to facilitate wicking of perspiration and to inhibit growth of microbes.

While undergarments have been demonstrated in the above disclosure, it should be well understood that other types of garments fall within the scope of the invention. For example, outer shirts employing bamboo fabric liners in the armpit areas would benefit from the moisture wicking an anti-microbial feature of the invention.
The above described embodiments, while including the preferred embodiment and the best mode of the invention known to the inventor at the time of filing, are given as illustrative examples only. It will be readily appreciated that many deviations may be made from the specific embodiments disclosed in this specification without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is to be determined by the claims below rather than being limited to the specifically described embodiments above.
