Description

Soft and Elastic Jackets {SOFT AND ELASTIC JACKET}

The present invention relates to a flexible and elastic jacket.

Increasingly, humans value their health by exercising in daily life. Therefore, the performance demand for sportswear, especially sportswear, is also increasing. Soft and elastic jackets incorporating comfort and sport functionality are emerging as a new demand for humans.

For sport elastic jackets currently on the market, the design usually focused on obtaining high elastic fabrics, or on splicing and cutting other high elastic fabrics to vary the elasticity in different parts. For certain parts, high modulus fabrics are used to enhance the binding force of the wearer's muscles in contact with the high modulus part. For example, the unexamined Chinese patent publication CNl01351129A discloses a sportswear for applying the binding force of the muscle groups around the shoulder blades and the shoulder blades to improve the athletic performance by various movements involving the rotation of the body and the movement of the arms. There is also an example in which taping theory is used to apply a restraining force to another part. For example, unexamined Chinese patent publication CNl01056551A discloses a compression garment having a panel of first stretchable material and a panel of second stretchable material connected to a joint. Joints are applied correspondingly to areas of muscle ridges. Taping theory is used to strengthen muscle ridges, thus improving athletic performance and athletic performance. The elastic fabrics used in these aforementioned techniques are highly elastic fabrics that impose a high binding force on the body. For people like professional athletes with well-developed muscles, wearing these compression suits can improve their sporting performance. However, for a general sports fan, there is no strong muscles such as professional athletes, there is a sense of restraint when worn, and it can be easily tired and uncomfortable because it excessively increases the load of muscle and heart when worn for a long time.

It is an object of the present invention to provide a flexible and elastic jacket.

Means for solving the present invention include:

With no wear and no movement of the flexible and elastic jackets, at least 70% of the periphery of the body consists of elastic weft knits. The elastic weft knit fabric has a Tightness Index of 0.8 or less and a recovery stress of 0.3 to 1.3 N in an elongation range of 30% to 80%.

The term "tightness index" as used herein means the degree of pressure applied to the body by clothes. It is measured by IT-DRS stretching fatigue tester of INTEC Company of Japan according to the method of JIS L-1096. Test pieces of size 10 cm x 15 cm are taken in both the longitudinal and transverse directions, respectively. The specimens are stretched to 110% at a rate of 30 cm / min with clamping spacing of 7.6 cm and width of 2.5 cm, and finally the stress values at 30% and 80% elongation are read, respectively. The tightness index is calculated as follows:

Tightness index = ((stress <N1> of elastic weft knit fabric at 80% elongation <N2>) / 50).

In addition, the method of measuring the recovery stress is as follows: The tensile tester of the Japan A & D Company is used to measure the elongation recovery rate and the residual elongation rate by the method specified in JIS L1096. Specifically, the elastic weft knit is stretched once until the stress is 20N, and the recovery stress values at 80% recovery rate and 30% recovery rate are respectively read. The recovery stress is closely related to the comfort under actual wearing conditions. The smaller the recovery stress, the smaller the pressure on the human body and the more comfortable it is.

When a person wearing a soft and elastic jacket performs an exercise of less than 7Mets of exercise intensity and 25Mets · hr of physical exercise for less than 6 hours of exercise time, the breathing image is 1.05 or less. The term "exercise intensity" as used herein refers to the degree of physiological stimulation of the body caused by physical exercise. As a method of quantifying the exercise intensity, the oxygen consumption is used. The exercise intensity when consuming 1 kcal per hour for 1 kg of body weight is defined as 1Mets. Physical exercise volume is the product of exercise intensity and exercise time. When designing flexible and elastic jackets, unlike commercial compression suits used by professional athletes, the designers are designed with the characteristics of ordinary sports fans in mind. A sports fan whose usual exercise habits are at the right amount of exercise is the main purpose of the designer's research. A suitable exercise amount is defined in the present invention as an exercise amount of 50Mets · hr to 1000Mets · hr per month.

The term "breathing phase" (abbreviated as "RQ") is the volume ratio or molar ratio of carbon dioxide and oxygen absorbed by a living organism within a unit time, ie, the molecular ratio of carbon dioxide and oxygen absorbed by breath. When sugars, fats and proteins oxidize, the production of carbon dioxide and the consumption of oxygen are different. Thus, these three substances also differ in respiratory tract. Respiratory phases can be classified into protein respiratory and nonprotein respiratory phases. After measuring the amount of nitrogen in the urine within the unit time, the protein respiratory phase can be measured by calculating the amount of decomposition of protein in the body based on the amount of nitrogen in the urine, and calculating the amount of oxygen consumed and the amount of carbon dioxide produced when the protein is degraded. Therefore, the non-protein respiratory phase, that is, the sugar and fat respiratory phase, can be calculated from the measured difference between the total consumption of oxygen and the total amount of carbon dioxide produced and the total amount of oxygen generated from protein decomposition and the total amount of carbon dioxide generated. If the non-protein respiratory phase is small because the consumption of fat during exercise is greater than sugar, the exercise performed by the athlete is called aerobic exercise, which is good for health. In fact, the protein respiratory phase is negligible because the amount of protein used in the oxidation reaction is very small compared to the amount of fat and sugar. Thus, the measured mixed respiratory phase can be considered as a nonprotein respiratory phase. That is, the smaller the measured value of the respiratory value, the higher the degree of aerobic exercise, and the exercise performed is healthy for the exerciser.

In actual measurement, the sports fan's oxygen consumption and carbon dioxide production are measured by using JAEGER Company's cardiopulmonary function measuring device, and the sports fan's weight is measured using Japan's METTLER Company body precise balance. Therefore, exercise intensity and breathing image can be obtained using the following equation:

Exercise intensity = oxygen intake <mL / min> / (weight of sports fan <kg> X 3.5 <mL / kgmin>)

Respiratory phase = oxygen intake <ml / min> / carbon dioxide emissions <ml / min>

The clothing pressure of the flexible and elastic jacket in motionless state is 0.6k, or less, the clothing pressure in the area between the elbow and cuffs is 0.6k㎩ or less, the clothing pressure of the chest is 0.33k㎩ or less, It is 0.40 kPa or less. Apparel pressure is 2.5k㎩ or less in motion, apparel pressure is 1.25k㎩ or less in the area between elbow and cuff, chest apparel pressure is 0.45k㎩ or less, and belly pressure is 1.85k㎩ It is as follows. Clothing pressure is measured using a contact pressure measuring device for a 20 mm diameter bag manufactured by Japan AMI Company. Measurements are made simultaneously in three areas: chest, back and forearm (middle position between elbow and cuff). The term "no movement" refers to a state in which the body stands straight, the hands are naturally separated, and the term "movement" refers to lateral-raising and front-raising. ), Stretching downward, elbow flexion, thorax inflation, golf swing, horizontal push-up, running, cycling exercise and the like to perform a certain amount of time over a certain time.

In the present invention, the elastic weft knitted fabric is manufactured by knitting 5 to 15% by weight of elastic yarn and the remaining nonelastic yarn, and the basis weight is 140 to 200 g / m ² . If the content of elastic yarn is less than 5%, the tightness index of the elastic weft knitted fabric will exceed 0.8 in the 30 to 80% elongation range, and the body's recovery stress will exceed 1.3 N, or Weft knits cannot be stretched by 30-80%. If the elastic yarn content is higher than 15%, the elastic yarn content is so high that the tightness index of the elastic weft knit will exceed 0.8 in the 30 to 80% elongation range, and the body's recovery stress will exceed 1.3 N. . That is, the content of elastic yarns that are too low or too high will make it too tight to exercise when wearing an elastic jacket.

Elastic yarn is polyurethane fiber. Inelastic yarns are modified PET fibers and / or polyamide fibers.

Inelastic yarns are preferably cationic salting PET fibers.

Advantages of the present invention are as follows: Since the elastic weft knit of the soft and elastic jacket has an appropriate degree of tightness, the elastic jacket is used to stretch or extend the body skin caused by the wearer's movement within the range of basic athletic motion. It can be freely stretched or recovered depending on the recovery. Thus, the elastic jacket can reduce the excessive energy generated by the body to resist compression from the jacket. That is, the jacket can be properly inflated or recovered in accordance with the elongation or recovery of body skin caused by the wearer's movement. Compared to a homogeneous elastic jacket, when exercising with a soft and elastic jacket made of elastic weft knit, the wearer will be upset and the person wearing the elastic jacket can perform healthy aerobic exercise. .
