Abstract
Mosquito resistant textiles and garments are provided that demonstrate resistance to mosquito bites without the use of pesticides or chemicals. The textiles and garments provide 90% or more resistance to mosquito bite resistance.
Claims21
A superfine knitted textile comprising a superfine blended yarn comprising a nylon and a polyurethane,
- wherein the blended yarn is knitted in a single jersey knit to form the superfine knitted textile having a textile thickness of about 300 μm or less and a plurality of pores having an average pore size of about 27.5 μm or less.
A spacer fabric textile comprising a front layer and a back layer, and further comprising a pile layer joining the front layer and the back layer,
- wherein the textile has a plurality of pores having a minimum pore size and a minimum thickness;
- wherein the pores have a pore size smaller than a maximum pore size sufficient to provide mosquito bite resistance based upon the minimum thickness of the textile;
- and
- wherein the minimum thickness is sufficient to provide mosquito bite resistance based upon the minimum pore size.
A textile having a plurality of microscopic pores,
- wherein the pores have a pore size of about 20 μm, about 19 μm, about 18 μm, about 17 μm, about 16 μm, about 15 μm, or less, and
- wherein one or more of the following is adjusted to provide at least 95%, 99%, or 100% mosquito bite resistance:
- (i) a thickness of the textile, (ii) a minimum pore size, (iii) a pore tortuosity, (iv) a pore shape, (v) a number of structures external or internal to the pores that prevent bending of a mouth part sheath of a mosquito, and (vi) a presence of fine structures on the external or internal of the pores that hit an antenna or other sensor organ of a mosquito when on a surface of the textile.
A mosquito-resistant garment comprising at least one textile having a bite resistance of at least 90% when measured according to one or both of the in vivo feeding bioassay and the arm-in-cage test described herein.
