Soft and elastic jacket

Abstract

A soft and elastic jacket is provided. No less than 70 percent of the body circumference of the soft and elastic jacket is composed of an elastic weft knitted fabric, when the soft and elastic jacket is in a motionless state without being worn. The elastic weft knitted fabric is produced by knitting 5˜15% weight of elastic yarns with the rest of non-elastic yarns, and it has a basis weight of 140˜200 g/m 2 . The elastic weft knitted fabric has a tightness index of not greater than 0.8 and a recovery stress of 0.3˜1.3 N at an elongation range of 30˜80%. The respiratory quotient is not greater than 1.05, when a person wearing the soft and elastic jacket exercises at an intensity of less than 7 Mets and a body exercise amount of not greater than 25 Mets·hr for an exercise time of less than 6 hrs. The soft and elastic jacket has a clothing pressure of 0.6 kPa or less in a motionless state, and 2.5 kPa or less in a motion state.

1 . A soft and elastic jacket wherein no less than 70 percent of the body circumference of the soft and elastic jacket is composed of an elastic weft knitted fabric, when the soft and elastic jacket is in a motionless state without being worn, the elastic weft knitted fabric has a tightness index of not greater than 0.8 and a recovery stress of 0.3˜1.3 N at an elongation range of 30˜80%. 
     
     
         2 . The soft and elastic jacket according to  claim 1  wherein the respiratory quotient is not greater than 1.05 when a person wearing the soft and elastic jacket exercises at an intensity of less than 7 Mets and a body exercise amount of not greater than 25 Mets·hr for an exercise time of less than 6 hrs. 
     
     
         3 . The soft and elastic jacket according to  claim 1  wherein the soft and elastic jacket has a clothing pressure of 0.6 kPa or less in a motionless state, and 2.5 kPa or less in a motion state. 
     
     
         4 . The soft and elastic jacket according to  claim 3  wherein the clothing pressure in a motionless state is 0.60 kPa or less at a portion between the elbow portion and the wrist portion, 0.33 kPa or less at the chest portion, and 0.40 kPa or less at the back side. 
     
     
         5 . The soft and elastic jacket according to  claim 3  wherein the clothing pressure in a motion state is 1.25 kPa or less at a portion between the elbow portion and the wrist portion, 0.45 kPa or less at the chest portion, and 1.85 kPa or less at the back side. 
     
     
         6 . The soft and elastic jacket according to  claim 1  wherein the elastic weft knitted fabric is produced by knitting 5˜15% weight of elastic yarns with the rest of non-elastic yarns, and has a basis weight of 140˜200 g/m 2 . 
     
     
         7 . The soft and elastic jacket according to  claim 6  wherein the elastic yarns are polyurethane fibers. 
     
     
         8 . The soft and elastic jacket according to  claim 6  wherein the non-elastic yarns are modified polyethylene terephthalate fibers and/or polyamide fibers. 
     
     
         9 . The soft and elastic jacket according to  claim 8  wherein the non-elastic yarns are cationic dyeable PET fibers.
