Abstract

This invention discloses unique nonwoven fabrics that may be constructed using various nonwoven processes that are resistant to mosquito and other commonly known bugs without any chemicals treatments commonly used for mosquito and bug repellency. The nonwoven fabrics may be made using any type of fibers and their blends such as natural, synthetic, high performance, fire resistant, antimicrobial, microfibers, etc., that are bonded within the fabric matrix.

Description

MOSQUITO AND INSECT BITE RESISTANT NONWOVEN FABRICS WITHOUT CHEMICAL TREATMENT
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority to provisional application
61/572,006 which is hereby incorporated by reference in its entirety.
DESCRIPTION
[0002] Today, most bug resistant garment and other applications use traditional woven fabrics treated with mosquito or other bug repellent chemicals. The application of such chemicals as DEET and Permethrin used in the industry is a concern for the environment. The treatment adds cost and the chemicals are added to the woven fabrics in a separate step after dyeing, printing and finishing the woven fabrics. Additionally, there is no guarantee that treated fabrics will completely prevent mosquitoes from biting the wearer of the garments. Thus there is a need to come up with a fabric that does not contain any bug repellent chemicals.
[0003] In order to develop a fabric that prevents the mosquito or other bugs to pierce their proboscis into the body to initiate a bite, one needs to understand the differences in construction between the traditional woven and knitted fabrics and the novel nonwoven fabrics of the current invention. As shown in Figure 1, woven and knitted fabrics are two-dimensional structures that are made of warp and fill yarns that contain holes. This type of construction makes it easy for the insect to enter their proboscis to initiate a bite on the human skin. Nonwoven fabrics, on the other hand, are not woven using the loom as indicated by their name and are made directly from individual fibers in much fewer processing steps than woven fabrics. As shown in Figure 1, nonwoven fabrics are three-dimensional structures that are impervious to many elements and they have been used for filtration of various particles in automotive and other industries. The holes present in the nonwoven fabrics do not run straight-through the fabric and are not interconnected and thus offering what is known as a "tortuous path" for any element passing through the fabric. For these fabrics, a mosquito or any bug will not be able to penetrate the fabric using their proboscis to initiate a bite on the human skin. The nonwoven fabrics need not be treated with mosquito or other bug repellent chemicals to be effective against the bug bites.
[0004] Nonwoven fabric technologies offer innovative solutions with improved scale of economy because of the fact that the machines can be run at several hundred feet per minute. The nonwoven fabrics can be made using various known methods such as needle punched, spunlaced, spunbonded, stitch-bonded, thermal bonded, chemical bonded, melt blown, elctrospun etc. The nonwoven fabrics of the current invention have very good air permeability to keep the wearer comfortable in all environments. The nonwoven fabrics can be made durable as in the case of needle-punched plus spunlaced structures or disposable as in the case of spunbonded, thermal bonded and laminated etc.
