Definitions

  • the present invention relates to a tights (also called compression clothing) and protective gear, in particular to a layered structure arranged on the tights and the protective gear for generating different pressures on a certain part of the user's human body, and a preparation method and belt The tights and protective gear with the layered structure.
  • Compression clothing and compression protective gear can produce pressure on the skin and muscles of the body. Its functions are as follows: 1. Protect the plump and prone to tremor body, that is, reduce the muscle vibration in this part to reduce the movement of this part of the muscle. The risk of injury due to excessive vibration. 2. Restrict the body to be protected, reduce the excessive vibration of the muscle during exercise, so as to reduce the excessive energy consumption due to frequent vibration of the muscle. 3. After putting on the tights or protective gear, it can provide pressure on the body surface of the human body and stimulate the proprioception of the brain, so that the wearer has a vigilant awareness of the need to protect the pressured parts of the tights or protective gear at all times. Will reduce the risk of injury.
  • the muscles of some vulnerable parts of the body need to be protected by a certain amount of pressure on tights or protective gear, while other parts can be ignored in this way.
  • the parts that need to be protected can be divided into areas (referred to as partitions) according to the required pressure for partition management.
  • the tights currently on the market are mainly divided into the following two types:
  • the first one is made of elastic fabrics.
  • the size of the tights and the size of the relevant parts of the wearer’s body should be smaller, that is, the wearer is wearing it.
  • the fabric of the tights will be deformed, so that the tights can exert a certain pressure on the human body to achieve the purpose of protecting the body.
  • the actual leg circumference of a wearer is 50cm
  • the leg circumference of the corresponding tights leg is 45cm.
  • the fabric at this position is stretched from 45cm to 50cm, thereby generating pressure on the legs. .
  • the shortcomings of this type of tights are: because the tights are integrated, the pressure on all parts of the wearer’s body is equal, and it cannot achieve the purpose of adapting and applying pressure for differential pressure (that is, it requires a large amount of pressure). For the pressure-protected part, the tights should produce greater pressure on this part, and the parts that do not need greater pressure protection are the pressure of the tights.
  • the second is to hollow out the area that needs greater pressure protection on the basis of the former garment (hereinafter referred to as the zone), and then use a fabric with a larger elastic modulus to cut into a set shape. , Using the sewing or hot pressing process to splice the sheet material on the corresponding partition (hereinafter referred to as the spliced sheet material).
  • the muscles of the front part of the thigh tend to vibrate during exercise, so the muscles in this part need to be protected by applying greater pressure.
  • the part is hollowed out first, and then the corresponding shape and greater elastic modulus are pre-cut. The pieces are spliced in this partition.
  • the leg When the pull tab material and the main body fabric are simultaneously subjected to the external support force generated by the same body part (that is, they are stretched by the body wear part, such as the leg of the tights worn on the user, the leg is tightened on the leg, due to the leg circumference It is larger than the leg circumference when the corresponding tights is in a natural state. For the leg, it is subjected to the pressure exerted by the tights. For the tights, when the legs stretch the trouser legs of the tights outwards), In the circumferential direction surrounding the corresponding body part, the spliced sheet material and the body fabric of the tights will mutually restrain each other.
  • the elastic modulus of the spliced sheet material is greater than that of the main body fabric
  • the elastic deformation of the spliced sheet material is smaller than that of the main body fabric. Therefore, in the circumferential direction, under the action of the same external support force, the main body fabric will undergo transitional deformation, which will generate a force greater than the preset pressure on the corresponding body part. At the same time, the transitional deformation of the main body The fabric will generate a greater tensile force on the spliced sheet material, so that the spliced sheet material generates a pressure less than the preset pressure on the corresponding body part.
  • Classification of compression protective gear This type of protective gear is also made of soft material in a cylindrical shape and can be put on a certain limb of the human body to protect this part of the limb.
  • the protection principle is the same as the aforementioned tights.
  • the protective gear currently on the market is mainly divided into two categories: the first category is the protective gear using woven fabrics. This kind of protective gear uses a uniform fabric for cutting and sewing, so it cannot achieve the function of partition pressure; (same as tight-fitting Clothing principle).
  • the second category the use of knitted fabrics, the problems are: 1) The fabric is thick and has poor wearing comfort. 2) The high and low compression zone and pressure value cannot be arbitrarily designed due to technological limitations. 3) Each product takes a long time to make and the process cost is high.
  • the technical problem to be solved by the present invention is to provide a layered structure that is arranged on tights and protective gear and can effectively protect the body's body according to the characteristics of different protection pressures required by human muscles during exercise, and a preparation method thereof And body protection supplies.
  • the technical solution adopted by the present invention is: the layered structure of the present invention for adjusting the partition pressure on the tights and protective gear is characterized in that it consists of a surface layer and at least one layer that is penetrated into the surface layer pores
  • the surface layer is a knitted or woven elastic material; the elastomer layer is TPE, TPU or other polymer elastic materials.
  • the surface layer is a sheet made of nylon, polyester, elastic yarn or other elastic fabrics and is individually cut and fixed on the corresponding partition of the tights or protective gear, or the surface layer is The fabric of the tights or the elastic fabric on the protective gear.
  • the elastic modulus of the composite layer is greater than the elastic modulus of the surface layer therein.
