Abstract

An insect-proof, form-fitting undergarment is provided having top and bottom parts formed of selected breathable materials and having omnidirectional stretch properties, and which top and bottom parts may be securely joined at the waist to prevent insect entry. A superfine knitted fabric is utilized to prevent insect bites.

First claim

We claim:

1. A mosquito-bite protective undergarment, comprising:
(a) an upper body form-fitting portion comprising:
a torso section comprising a neck opening;
a left arm section and a right arm section, each of the arm sections comprising
an inner terminus attached to the torso section and an outer terminus; and

(b) a lower body, form-fitting portion comprising:
a waist section; and
a left leg section and a right leg section, each of the leg sections comprising an inner terminus attached to the waist section and an outer terminus;

wherein one or both of the upper body form-fitting portion and the lower body, form-fitting portion comprise a synthetic knit material comprising:
about 70% to about 90% by weight of a polyamide fiber based upon a total weight of the synthetic knit material, wherein the polyamide fiber has a fiber thickness of about 15 to about 25 denier count; and
about 10% to about 30% of an elastane fiber based upon the total weight of the synthetic knit material, wherein the elastane fiber has a fiber thickness of about 10 to about 20 denier count,
wherein the synthetic knit material has a weight of about 2.5 to about 3.0 ounces per square yard, and an average pore size of about 27 μm to about 34 μm.

2. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material has a stretch in a width of the synthetic knit material of about 200% to about 260%.

3. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material has a stretch in a length of the synthetic knit material of about 130% to about 190%.

4. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material has a stretch in a width of the synthetic knit material of about 200% to about 260% and a stretch in a length of the synthetic knit material of about 130% to about 190%.

5. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material is a jersey plated knit structure having about 80-90 wales.

6. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material is a jersey plated knit structure having about 110-120 courses per inch.

7. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material has a jersey plated knit structure having about 80-90 wales and about 110-120 courses per inch.

8. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material has a mosquito bite resistance of about 99% or more when measured according to an in vitro feeding bioassay.

9. The mosquito-bite protective undergarment according to claim 1 , wherein the synthetic knit material has a mosquito bite resistance of about 99% or more when measured according to a Mosquito Arm-in-cage Bite test.

10. A mosquito-bite protective undergarment, comprising:
an upper body form-fitting portion comprising:
a torso section comprising a neck opening; and
a left arm section and a right arm section, each of the arm sections comprising
an inner terminus attached to the torso section and an outer terminus, wherein the upper body form-fitting portion comprises a synthetic knit material comprising:
about 70% to about 90% by weight of a polyamide fiber based upon a total weight of the synthetic knit material, wherein the polyamide fiber has a fiber thickness of about 15 to about 25 denier count; and
about 10% to about 30% of an elastane fiber based upon the total weight of the synthetic knit material, wherein the elastane fiber has a fiber thickness of about 10 to about 20 denier count,
wherein the synthetic knit material has a weight of about 2.5 to about 3.0 ounces per square yard, and an average pore size of about 27 μm to about 34 μm.

11. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material has a stretch in a width of the synthetic knit material of about 200% to about 260%.

12. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material has a stretch in a length of the synthetic knit material of about 130% to about 190%.

13. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material has a stretch in a width of the synthetic knit material of about 200% to about 260% and a stretch in a length of the synthetic knit material of about 130% to about 190%.

14. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material is a jersey plated knit structure having about 80-90 wales.

15. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material is a jersey plated knit structure having about 110-120 courses per inch.

16. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material is a jersey plated knit structure having about 80-90 wales and about 110-120 courses per inch.

17. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material has a mosquito bite resistance of about 99% or more when measured according to an in vitro feeding bioassay.

18. The mosquito-bite protective undergarment according to claim 10 , wherein the synthetic knit material has a mosquito bite resistance of about 99% or more when measured according to a Mosquito Arm-in-cage Bite test.

19. A mosquito-bite protective undergarment, comprising:
a lower body, form-fitting portion comprising:
a waist section; and
a left leg section and a right leg section, each of the leg sections comprising an inner terminus attached to the waist section and an outer terminus;

wherein the lower body, form-fitting portion comprise a synthetic knit material comprising:
about 70% to about 90% by weight of a polyamide fiber based upon a total weight of the synthetic knit material, wherein the polyamide fiber has a fiber thickness of about 15 to about 25 denier count; and
about 10% to about 30% of an elastane fiber based upon the total weight of the synthetic knit material, wherein the elastane fiber has a fiber thickness of about 10 to about 20 denier count,
