The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
(1) preparation of uvioresistant non-weaving cloth
Accurately take by weighing the 50mg forulic acid, the 0.95g polyacrylonitrile is dissolved in the 10ml N,N-dimethylacetamide and is made into spinning solution.At voltage 12kV, shower nozzle is 15cm with the distance of accepting screen, and the spinning head extruded velocity is under the condition of 3ml/h, the non-weaving cloth of spinning system.
(2) the both macro and micro pattern of non-weaving cloth
By the non-weaving cloth photo (Fig. 1) that digital camera is taken, can see that the non-weaving cloth surface is very smooth.By stereoscan photograph (Fig. 2), can see that Fiber Distribution is even, diameter is thinner, between 100～300nm.
(3) uvioresistant effect measuring
At present fabric uvioresistant effect evaluation method has spectrophotometer method, uitraviolet intensity cumulative method, variable color fade method and direct-vision method etc., and wherein spectrophotometer method is more excellent.Spectrophotometer can detect the transmittance under each different wave length, is the most popular and method in common in the world at present.Main evaluation criterion both domestic and external has at present: the GB/T18830-2002 of China, Australia/Zelanian AS/ZS4399, the AATCC183-1998 of the U.S., ASTM draft D13.65, the BS7914-1998 of Britain, BS7974-1999 and the PrEN of European Union 13758 etc.
Ultraviolet Protection Factor (UPF) is the parameter of expression fabric ultraviolet protection ability, the ratio of its ultraviolet radiation effect that to be the ultraviolet radiation effect that calculates when not using shielding calculate when using shielding.The UPF value is extensively adopted in the world, and the while writes Australia/New Zealand Standard as the characteristic evaluating parameter of fabric uvioresistant characteristic, and numerical value and the degree of protection of UPF see Table 1, and the UPF value is high more, and the uvioresistant performance of fabric is strong more.Stipulate that in PrEN13758 and ISO motion the UPF value should be greater than 30, the UVA transmittance is not more than 5%; In China's standard, deliberated index regulation UPF value＞30, UVA transmittance≤5%.
Numerical value and the degree of protection of table 1UPF
Experimental result sees Table 2, and different non-weaving cloth thickness has different uvioresistant effects, and this is that the ultra-violet absorber that is loaded with is many more, so the uvioresistant effect is good more because non-weaving cloth is thick more.
