Wound care theory drives the development of medical dressings
In the human development process, skin trauma has always been an inevitable medical problem. Primitive society, people from the animals and plants and minerals to extract the material to deal with the wound. The earliest evidence of wound healing in the West was that the people of Mesopotamia were treated with clay for wound healing. The earliest human case with cotton fiber, horse mane as a suture suture and wound dressing was found in the four thousand years old history of Egyptian Pharaoh's tomb - a mummy on the right foot has a clear right Wounds are traces of simple handling.

Before 1867, doctors had not had surgery on surgical instruments or used gauze to stop bleeding and dressing wounds. In 1867, the founder of the modern sterile surgery, the British Joseph Liszt learned Louis Pasteur's "high temperature sterilization" theory, created a sterile surgical theory. He was rinse the surgical instruments and soaked gauze with carbolic acid during surgery, the first to apply sterile gauze to wound care and invented sterile medical sutures. Since then, the cotton gauze products as the representative of the "dry breathable" wound care theory to become mainstream. Materials based on this principle of care are emerging.
For a long period of time thereafter, the wound dressing product did not always jump out of the cotton gauze pattern. However, during the Second World War, gauze and other sources of raw materials, coupled with cotton gauze dressing wound wound dressing pain, secondary trauma and ulcers and other difficult treatment of wound healing, forcing people to find a Traditional medical dressings compared to the higher efficiency, not so rely on high-quality yarn of the new light fabric. In such a demand prompted by the use of plant materials made of non-woven fabrics. This non-woven fabric can be used as a separate wrapping material, but also with other materials made of composite materials bandaged. At the same time, people also developed without the use of adhesives but with spunlace reinforcement fiber method, that is, spunlace.
Prior to the 1960s, wound care was conducted under the guidance of dry healing theory. In the mid-20th century, based on the theory of wet healing, polymer materials such as polyamide, polyethylene, polypropylene, ethylene polymers and so on began to be used in medical dressings and rapid development.
Into the 90s of last century, with the aging of the world's population, and the elderly are closely related to bed sores, ulcers and other chronic wound care in the West to become an increasingly serious health problems, the world's medical and health areas more and more attention to research and development of high-tech medical dressings The Encouraged by the governments of developed countries, many large health materials companies have invested a lot of money and material resources, have launched a series of more convenient, better performance of high-tech medical dressings. At present, the vast majority of wounds can be made of synthetic materials made of dressings instead of animal and plant raw materials dressings.
