| Research in textile production, spinning and weaving and its poison in the ware, harmful material comes from the fiber raw material and process primarily medicine or help.For this, many nations is especially Euro-American to prosper the nation to release the environmental protection label of the textile product one after another, the among them the most important be spun and weave by Europe 《Oko- Tex- Standard that examine international environmental protection spinning association that organization together constitute' s establishment 100 standard 》 . In that standard 2000 version, it was clear and definite to ruled the spinning finished product poisoned harms the material and tallest capacity, including primarily the pH value, formaldehyde contain the deal, can extract the heavy metals, agricultural remaining , living on behalf benzene fen , accidentally nitrogen dyestuff, allergic dyestuff, flam retardant sorting, dye a series of and safe index sign in an etc. in prison.We say the pollution of the environment of PVA, is not that PVA can' t decline the solution, but it is hard , if declination to solve the PVA completely, inviting to need about three years time, long time is true hard allowing for the environment. At liquid waste processing hour, use three year the complete living creature declines to solve the PVA, this too is to not agree with to match actual of, therefore, the living creature declines the solution the hard attaining the pre-arranged purpose.The PVA backs to strach of discard the hard living creature in liquid declines the solution, resulting in the fact that pollution has been and can' t deny to the environment, but for realizes to living to turn to back the size, try to make the PVA resolves the enzyme to have the biggest practical meaning equally, the PVA resolves at the same time the enzyme can also used to the dirty water in spinning handles.The green size anticipates, is ecosystem to point to should can pass the our country textile product standardsHJBZ30-2000_s( namely:International Oko- Tex- Standard 100 standard) after the examination, obtain the size that ecosystem marking anticipate. Ising not a certain size to anticipate oneself in production factory house can from life .Because the PVA recovery is hard and in actual production applied, therefore for the sake of contaminative problem that solution PVA, depend on the very big degree development action for the PVA new size anticipates.Connect a method for changing the sex starch regard starch as the raw material, passing chemistry or physicses, connect a some other polymer on the main chain in its big numerator, because of connecting a side chain is an applied function good polymer, connect the some important problem in etc. in a pollution for the main chain is a starch, therefore connecting change the sex starch has got good top size function with living creature declining solving sex, is the best size to act for the PVA anticipating, can lowering sizing cost, resolving PVA to the environment resulting in, therefore connect a research for changing the sex starch size to anticipate with develop to have got the enormous and actual meaning with apply the foreground.Pass to spin cotton the technical improvement with increases, hairless feather yarn or little hair feather yarn products have become the possibility. This Tightness of" abrogate top size light size in " with" craft" of the foreground is an attention for can pleased information, deserving we ascending straching worker with thorough research.Here at the same time, we must see, the achievement of size is not much.The new good size have not be appeared, if ever three big size anticipate the key problem exsited in the species and also did not see effectively of solution. This have something to do with we systematically, thoroughly proceeding research not enoughly. This aspect causes the schoolparticularly to value with the think factory. |
