Abstract
Official abstract text for this publication.
A knitted fabric structure that includes a piezoelectric yarn having a piezoelectric material that produces a surface potential by input of an external force from an outside of the piezoelectric yarn; and an elastic yarn having stretchability knitted together with the piezoelectric yarn, wherein the piezoelectric yarn has a mixing ratio of 5% or more based on a whole of the knitted fabric structure.
First claim
Opening claim text (preview).
What is claimed is: 1. A knitted fabric structure comprising: a piezoelectric yarn comprising polylactic acid as a piezoelectric material and that produces a surface potential by input of an external force from an outside of the piezoelectric yarn, the piezoelectric yarn having a first loop; wherein the first loop does not include an elastic yarn; and an elastic yarn having an elongation recovery rate of 40% or more, the elastic yarn having a second loop, wherein the second loop of the elastic yarn is hooked to the first loop of the piezoelectric yarn, wherein the piezoelectric yarn has a mixing ratio of 5% or more based on a whole of the knitted fabric structure, and wherein the elastic yarn has a mixing ratio of 35% or more based on the whole of the knitted fabric structure. 2. The knitted fabric structure according to claim 1 , wherein the piezoelectric material is in the form of electric field producing filaments. 3. The knitted fabric structure according to claim 2 , wherein a number of the electric field producing filaments in the piezoelectric yarn is 2 or more. 4. The knitted fabric structure according to claim 2 , wherein the electric field producing filaments are in a twisted form in the piezoelectric yarn. 5. The knitted fabric structure according to claim 2 , further comprising a dielectric around the electric field producing filaments. 6. The knitted fabric structure according to claim 1 , wherein the mixing ratio of the piezoelectric yarn is 65% or less based on the whole of the knitted fabric structure. 7. The knitted fabric structure according to claim 1 , wherein the elastic yarn is one selected from the group consisting of a yarn containing polyurethane, a nylon yarn having a woolly finish, and polytrimethylene terephthalate as a core yarn. 8. The knitted fabric structure according to claim 1 , wherein a degree of crystallization of the polylactic acid is 20% or more. 9. The knitted fabric structure according to claim 1 , wherein the piezoelectric material does not comprise an additive. 10. The knitted fabric structure according to claim 1 , wherein the surface potential is 0.1V or more. 11. The knitted fabric structure according to claim 1 , wherein a fiber strength of the piezoelectric yarn is 1 to 10 cN/dtex. 12. The knitted fabric structure according to claim 1 , wherein the piezoelectric yarn is arranged at a position where the knitted fabric structure is subjected to stretching during the wearing of the knitted fabric structure. 13. The knitted fabric structure according to claim 12 , wherein the position where the knitted fabric structure is subjected to stretching during the wearing of the knitted fabric structure is on a toe side of a ball of a foot. 14. A sock comprising the knitted fabric structure according to claim 1 . 15. A leggings comprising the knitted fabric structure according to claim 1 . 16. An arm cover comprising the knitted fabric structure according to claim 1 . 17. A shirt comprising the knitted fabric structure according to claim 1 .
