鞋楦数字化是鞋类设计与制造的核心技术

主要论述了“鞋楦数字化”是设计与制造高质量鞋类产品的关键核心技术,及其对鞋楦企业设计制造鞋楦、制鞋企业设计制造高品质鞋产品、提升消费者在实际穿着鞋产品中对其舒适性、时尚性等方面体验的重要性。通过分析研究脚型与楦型、楦型与鞋型、鞋楦与鞋产品合脚舒适之间的关系,为设计人员正确掌握和运用各类鞋楦的设计尺寸数据、推动鞋楦标准化技术成果转化、适时修订相关国家标准,提供参考与依据。     

运动鞋感知舒适性层次分析体系构建

运动鞋是人们出行和运动常用的鞋型,其感知舒适性是评价运动鞋性能的重要指标。本文通过对民众和专家的调查,基于鞋各部位特性梳理出评价运动鞋感知舒适性的层次分析结构,通过对评价因素的层层对比,建立评价运动鞋感知舒适性的层次分析体系,在准则层中,鞋楦合脚性、中底缓冲性和帮面透气性是保证鞋舒适性的主要因素;在指标层中,前足合脚性、鞋内温度和湿度变化是运动鞋感知舒适性综合评价的重要参考指标。舒适的运动鞋要在保证合脚性的基础上提高中底缓冲性能,在鞋的设计与足功能相匹配前提下,结合运动特点提高鞋的透气性,优化运动时鞋腔的内环境。     

成鞋舒适性评估方法的研究

基于目前大部分企业对成鞋的检测只是常规的外观质量、卫生性能、强度检测等,没有形成评价成鞋舒适性的完整体系,无法对鞋靴舒适性度进行定级描述,系统分析归纳了影响成鞋舒适性的因素为心理舒适性因素和生理舒适性因素,并建立了一套可操作性强及评价结果科学、全面、准确的成鞋舒适性系统评估方法。     

影响鞋靴舒适性功能的五大因素

高品质的鞋靴不单有超凡脱俗的外观设计,更要具备鞋靴舒适性的诸多因素,这样才能足不同消费者的生理、心理的需要。鞋的舒适性是鞋的首要功能之一,而影响鞋靴产品舒适性的直接因素主要有五大类:鞋楦造型设计、帮样结构设计、底部件组合设计、材料种类的选用及生产工艺设计等。     

鞋的触觉舒适性研究进展

舒适是消费者对鞋品质的重要要求之一,鞋的舒适性是指人们在穿着过程中对鞋的心理和生理感受的综合评价,是指鞋符合人足形态结构和功能要求的程度。人对鞋舒适度的感觉主要包括视觉舒适度、嗅觉舒适度和触觉舒适度。本文通过对国内外近年来在鞋的触觉舒适性方面的研究进行综述,了解研究现状,并为今后进一步研究鞋的舒适性及制定鞋的舒适性标准提供借鉴和参考。综合分析以往研究结果可以发现,多种因素都可能影响受试者对鞋的舒适性的判断,各种因素间的相互影响也造成很难确定某因素对舒适性影响的规律。

Reliable identification of grapevine rootstock varieties using RAPD PCR on woody samples

Since grapevine ( Vitis spp .) rootstock material is being traded increasingly as disbudded woody material a lack of distinctive morphological features on such material necessitates an alternative and reliable means of identification. Methods described here were developed for rapid and efficient extraction of DNA from woody samples rich in phenolic compounds and polysaccharides, and for subsequent identification of varieties by RAPD PCR. Using these methods, and with the application of only one selected RAPD primer, we were able to differentiate sixteen rootstock varieties, including the seven varieties most commonly used in Germany. Problems commonly encountered with reproducibility of RAPD patterns were avoided by choosing primers with a dinucleotide sequence and a high G/C content that allowed a rather high annealing temperature of 45°C. Methods described here should also be useful for other horticultural crops, especially those with woody tissues rich in phenolic compounds and polysaccharides.     

An internet compendium of analytical methods and spectroscopic information for monomers and additives used in food packaging plastics

An internet website (http://cpf.jrc.it/smt/) has been produced as a means of dissemination of methods of analysis and supporting spectroscopic information on monomers and additives used for food contact materials (principally packaging). The site which is aimed primarily at assisting food control laboratories in the European Union contains analytical information on monomers, starting substances and additives used in the manufacture of plastics materials. A searchable index is provided giving PM and CAS numbers for each of 255 substances. For each substance a data sheet gives regulatory information, chemical structures, physico-chemical information and background information on the use of the substance in particular plastics, and the food packaging applications. For monomers and starting substances (155 compounds) the infra-red and mass spectra are provided, and for additives (100 compounds); additionally proton NMR are available for about 50% of the entries. Where analytical methods have been developed for determining these substances as residual amounts in plastics or as trace amounts in food simulants these methods are also on the website. All information is provided in portable document file (PDF) format which means that high quality copies can be readily printed, using freely available Adobe Acrobat Reader software. The website will in future be maintained and up-dated by the European Commission's Joint Research Centre (JRC) as new substances are authorized for use by the European Commission (DG-ENTR formerly DGIII). Where analytical laboratories (food control or other) require reference substances these can be obtained free-ofcharge from a reference collection housed at the JRC and maintained in conjunction with this website compendium.     

Aroma characterization of various apricot varieties using headspace–solid phase microextraction combined with gas chromatography–mass spectrometry and gas chromatography–olfactometry

The characterization of the aromatic profile of several apricot cultivars with molecular tracers in order to obtain objective data concerning the aromatic quality of this fruit was undertaken using headspace–solid phase microextraction (HS–SPME). Six apricot cultivars were selected according to their organoleptic characteristics: Iranien, Orangered, Goldrich, Hargrand, Rouge du Roussillon and A4025. The aromatic intensity of these varieties measured by HS–SPME–Olfactometry were defined and classified according to the presence and the intensity of grassy, fruity and apricot like notes. In the six varieties, 23 common volatile compounds were identified by HS–SPME–GC–MS. Finally, 10 compounds, ethyl acetate, hexyl acetate, limonene, β-cyclocitral, γ-decalactone, 6-methyl-5-hepten-2-one, linalool, β-ionone, menthone and (E)-hexen-2-al were recognized by HS–SPME–GC–O as responsible of the aromatic notes involved in apricot aroma and considered as molecular tracers of apricot aromatic quality which could be utilized to discriminate apricot varieties.     

Tests of potential functional barriers for laminated multilayer food packages. Part I: Low molecular weight permeants

The advent of the functional barrier concept in food packaging has brought with it a requirement for fast tests of permeation through potential barrier materials. In such tests it would be convenient for both foodstuffs and materials below the functional barrier (sub-barrier materials) to be represented by standard simulants. By means of inverse gas chromatography, liquid paraffin spiked with appropriate permeants was considered as a potential simulant of sub-barrier materials based on polypropylene (PP) or similar polyolefins. Experiments were performed to characterize the kinetics of the permeation of low molecular weight model permeants (octene, toluene and isopropanol) from liquid paraffin, through a surrogate potential functional barrier (25 μm-thick oriented PP) into the food simulants olive oil and 3% (w/v) acetic acid. These permeation results were interpreted in terms of three permeation kinetic models regarding the solubility of a particular model permeant in the post-barrier medium (i.e. the food simulant). The results obtained justify the development and evaluation of liquid sub-barrier simulants that would allow flexible yet rigorous testing of new laminated multilayer packaging materials.

The development of reference materials for paralytic shellfish poisoning toxins in lyophilized mussel. II: Certification study

This paper describes the second part of a project undertaken to develop certified mussel reference materials for paralytic shellfish poisoning toxins. In the first part two interlaboratory studies were undertaken to investigate the performance of the analytical methodology for several PSP toxins, in particular saxitoxin and decarbamoyl-saxitoxin in lyophilized mussels, and to set criteria for the acceptance of results to be applied during the certification exercise. Fifteen laboratories participated in this certification study and were asked to measure saxitoxin and decarbamoyl-saxitoxin in rehydrated lyophilized mussel material and in a saxitoxin-enriched mussel material. The participants were allowed to use a method of their choice but with an extraction procedure to be strictly followed. The study included extra experiments to verify the detection limits for both saxitoxin and decarbamoyl-saxitoxin. Most participants (13 of 15) were able to meet all the criteria set for the certification study. Results for saxitoxin.2HCl yielded a certified mass fraction of <0.07 mg/kg in the rehydrated lyophilized mussels. Results obtained for decarbamoyl-saxitoxin.2HCl yielded a certified mass fraction of 1.59+/-0.20 mg/kg. The results for saxitoxin.2HCl in enriched blank mussel yielded a certified mass fraction of 0.48 +/- 0.06 mg/kg. These certified reference materials for paralytic shellfish poisoning toxins in lyophilized mussel material are the first available for laboratories to test their method for accuracy and performance.
