The Research And Development On Spunlaced Medical Compresses

Spun laced medical compresses appeared during The II War, the gauze and other medical materials' s shortage made engineers find a new way to manufacture a light fabric. They found a more effective way compare to the one of traditional woven products. The researchers centralized to research on carding fiber, forming web, getting fabric, and bonding the web with glue. Then, they found a bonding way which needed to use not glue but spunlacing, this is so-called spunlacing. During the past more than ten years, the production and trade of spun laced medical compresses have been developing rapidly all over the world.Spun laced medical compresses includes mainly: wound compress, binding gauze, bandages, surgical gauze, eye gauze, self-stock compress, masks gauze, Wound Plaster, disinfectant gauze, X-ray detectable gauze, medical paster, medical adhesive tape, etc.Spun laced medical developed very rapidly and full-seally oversea, but it is not so popular in China. It is statisticed by investigation as below: first, technique reasons, such as: the web is too thick and fluffing, the web sticks to another, equality performance is bad, pharmacological program can' t be reached, wet intension is low, etc. : second, production cost is high, and compare to traditional woven products, spun laced medical compresses have not obvious price advantage; the third, the manufacture enterprises are smalI and separated, and hard to get scale benefit; the forth, the manufacturers don' t think much of it enough, and the investment put in the research on the new and functional products isn' t enough; the fifth, the reason of people' s consumption idea, etc. just because of all of the reasons above, the development of spun laced medical compresses of China drops far behind western countries' , and there are huge space to develop. My research includes such several parts below:First, technologically analyzed the question of spun laced medical compresses' spread, such as: the web is too thick and fluffing, the web sticks to another, equality performance is bad, pharmacological program can' t be reached, wet intension is low, etc. I have analyzed them carefully and deeply, and improve them from materials and techniques. Technologically solved spread question.Second, analyzed the products of the same category worldwide, included woven and spun laced medical compresses, and knew the basic things. Then deep into the end-user, and go into every large-scale representative hospitals to make market research, and found out the application thing. By research feedback, found the shortage of current compresses and the question existed in the market, and I developed several new type spun laced medical compresses which are rivalrous in the medical compresses markets and accord with market demand.The third, researched and developed funct ional compresses, suchas: Tencel fiber added medical compress, chit in added medical compress, antimicrobial added medical compress to meet the different demand of market.The forth, exper imented and produced the new compresses, and clinically appliedthem.By comparing to traditional woven medical compresses, I investigated and researched the market actuality, market foreground, and spread or application question of spun laced medical compresses systematically in this thesis. And I developed some new spun laced medical compresses, such as Tencel fiber added medical compress, chit in added medical compress, ant imicrobial added medical compress, etc. so I reached some conclusions:First, spunlaced medical compresses market oversea is in the ascendant now, but the one domestic is starting, so there is enormous developing potential.Second, every manufacturers should attach importance to the spread and appiication of spunlaced medical compresses, give more publicity and give more prophase investment.The third, in the course of developing of spunlaced medical compresses, we should regard cost control, besides the quality management.The forth, it' s a advantageous news for spunlaced medical compresses of the exte...
