treatmentwith an inorganic gas under a gas pressure of 0.01-10 torr tobestow hydrophily to one side of the fiber product containing atleast 50%synthetic fibers or semisynthetic fibers.  \n2.  The fiber products with different front and back functionsdescribed in Claim 1,wherein said fiber product is a woven,knitted or unwoven cloth made of nylon,polyester,acrylic,  \npolypropylene or acetate fibers,or a mixed spun fiber containingat least 50%such fibers.  \n3.The fiber products with different front and back functionsdescribed in Claim 1,wherein said inorganic gas is an oxygen gasor a gas which contains at least 10 vol%of oxygen gas.  \n# Detailed explanation of the invention\n\nThis invention relates to a fiber product with differentfront and back functions,and in particular this invention relatesto a fiber product wherein one side of the fiber has the hydro-phobic character of the original fiber and the other side ofthe fiber has hydrophilic property(moisture absorbence,perspir-ation absorbence and so on),without a substantial change in theexternal morphology and/or air permeability.  \nA variety of functions are demanded of recent clothingmaterials,particularly the outdoor wear such as sportswear,and  \nPage 3  \nthe trend is toward a multifunctional composite type in manycases.  For example,the materials to be used for such clothingtypically have different front and back functions which arecharacterized by having water repellency on the front yet havinghydrophilic properties such as moisture absorbability and perspir-ation absorbability on the back.  \nAdhesion or coating a proper processing chemical suitablefor the aim on the surface of the fibers is the method of  \nimparting different front and back functions to the fiber productand the coating method is perhaps the fastest way to do the job.Another method is a roller touch process or foaming processingmethod which employs a foaming medium.  \nThe prior arts which employed such processing chemicalsoften caused a change in the physical properties of the fibersurface,such as a modification of the external morphology of thefiber,its texture or air permeability.  For example,with thecoating process,the external surface of the fiber shows a non-coating surface which is different from the normal surface ofthe fiber and also interferes with the air permeability of thefabrics,all of which are undesirable.  On the other hand,withthe roller touching process,the problem of the seeping of chem-icals to the front and back of the fabrics has been great andin addition,both methods caused a deterioration of the \"hand\"of the processed fabrics or other properties,depending on thetypes ","cbCaiafFuJwI14RH","https://ap.wps.com/l/cbCaiafFuJwI14RH","pdf",1060197,34,"English","# Claims\n## Claim 1\n## Claim 2\n## Claim 3\n# Detailed explanation of the invention","[{\"question\":\"What is the core purpose of the fiber product in this patent?\",\"answer\":\"To give one side of the fiber product hydrophobic characteristics while the other side is hydrophilic, without a substantial change in external morphology or air permeability.\"},{\"question\":\"How does the invention create different front and back functions?\",\"answer\":\"It uses a low-temperature plasma treatment with an inorganic gas under 0.01–10 torr to impart hydrophilicity to one side.\"},{\"question\":\"What kinds of materials and fabric structures are covered by the claims?\",\"answer\":\"The claims cover woven, knitted, or nonwoven cloth made from nylon, polyester, acrylic, polypropylene, or acetate fibers, or mixed spun fibers containing at least 50% of such fibers.\"}]","FIBER PRODUCTS WITH DIFFERENT FRONT AND BACK FUNCTIONS - low-temperature plasma treatment | PDF",1789966437,86]
