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 / m2. 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.

Description

TECHNICAL FIELD[0001]This invention relates to a soft and elastic jacket.BACKGROUND ART[0002]People are increasingly paying attention to their own health, daily dietary and life quality, and people doing various kinds of exercises are increasing. Therefore, the people's requirements, especially the performance requirements for the exercise garments, such as sportswear, have been raised accordingly. A soft and elastic jacket integrating comfortableness with sports function becomes a new demand of the people.[0003]At present, for elastic jackets for sports available in the market, the designs thereof are usually focused on how to acquire high elasticity or on how to splice and cut different elastic fabrics such that the elasticity in different portions is different. For certain portions, high elastic fabrics are used to enhance tightening force on the wearer's muscles contacting these portions. For example, Chinese Unexamined Patent Publication CN101351129A discloses an exercise garme...

AI Technical Summary

Benefits of technology

[0004]The purpose of the present invention is to provide a soft and elastic jacket.

[0010]The term “respiratory quotient” (“RQ” for short) refers to the ratio of the volume or molar of carbon dioxide released to the volume or molar of oxygen absorbed in an organism in a specified time, i.e. the ratio of the molecular of CO2 released to the molecular of O2 absorbed in respiration. Sugars, fats and proteins have different CO2 outputs and O2 consumptions when oxidized. Therefore, these three substances have different respiratory quotients. The respiratory quotients can be classified as protein respiratory quotients and non-protein respiratory quotients. The protein respiratory quotient can be measured by measuring the amount of urinary nitrogen quantity in a specified time, and then calculating the amount of the protein decomposed in vivo based on the amount of urinary nitrogen, and calculating the O2 consumption and CO2 output during the decomposition of the proteins. Thus, the non-protein respiratory quotient, i.e., the respiratory quotient of the sugars and fats, can be calculated by subtracting the O2 consumption and CO2 output during the composition of the proteins from the measured total O2 consumption and total CO2 output. Since more fats are consumed than sugars are in an exercise, the exercise an exerciser does when the non-protein respiratory quotient is small is called as aerobic exercise, which is healthful. In fact, the amount of the proteins for oxidation is so small, in comparison with those of fats and sugars, it can be negligible. Thus, a mixed respiratory quotient so measured can be reckoned as non-protein respiratory quotient. In other words, the smaller the measured value of the respiratory quotient value is, the higher the degree of aerobic exercise an exerciser does is, and the healthier for the exerciser is.

[0016]The advantages of the invention are as follows: since the elastic weft knitted fabric of the soft and elastic jacket has an appropriate tightness degree, the elastic jacket can be stretched or recovered freely following stretching or recovery of the body skin caused by the wearer's movement within the range of normal exercise movement. Thus, the elastic jacket can reduce the energy excessively generated by human body for resisting the compression from the jacket. On the other hand, the jacket can timely expand or recover to follow stretching or recovery of the body skin caused by wearer's movement. As compared with the elastic jackets of the same kind, wearer will feel lighter, free of burden when wearing a soft and elastic jacket made of the elastic weft knitted fabric and exercising, and it is possible for a person wearing the elastic jacket to do aerobic exercise which is healthful.MODE OF CARRYING OUT THE INVENTION

Problems solved by technology

However, for ordinary sports enthusiasts, they may easily feel tired and discomfort, because these compression jackets may tighten the enthusiast's muscles too strong to a too tight state when worn, and may excessively increase burden on the muscles and even the hearts when worn for a long time due to the enthusiasts doing not have hard muscles like professional athletes.
