产业用:新升级谋划大未来——访中国产业用纺织品行业协会会长李陵申

中国产业用纺织品行业协会会长李陵申在接受记者采访时首先定义行业的转型升级——"产业用纺织品行业转型升级的确不同于传统纺织行业的转型升级概念"。李陵申指出,产业用纺织品又称技术纺织品,不存在转型,它和服装、印染等行业不一样,服装企业可由低端化向品牌化发展,印染企业可基于绿色、环保和社会和谐。转型升级     

基于“微笑曲线”的江苏织造行业转型升级路线分析

纺织产业在我国繁荣市场、扩大出口、吸纳就业、增加农民收入、促进城镇化发展等方面发挥着重要作用。在进入“十二五”之后，中国纺织产业又将向新兴战略产业和时尚产业的新定位迈进。如今全球纺织经济形势发生了巨大变化，中国劳动密集型产业正面临生产要素价格优势逐渐丧失、政策支持逐渐弱化，国际竞争对手迅速成长等一系列压力。中国纺织业必须尽快改观这种局面，才能在未来布局中跑赢对手。江苏是我国重要的纺织品生产基地和出口基地，逐渐形成了南通的家纺和色织、苏州盛泽的化纤织造、常州湖塘的织造产业等织造聚集区，本文针对江苏织造行业面临的问题，依据“微笑曲线”理论探讨其转型升级路线。     

实地调研国产中高端织机

期待长丝织造的绿色与智能

<正>长丝织造行业不仅要提高织造行业的智能生产水平,还要发展绿色制造截止到2014年底,全国拥有各类长丝织造设备(织机)近50万台,其中超过70%是喷水织机。从数据中不难看出喷水织机在长丝织造产业甚至是全国纤维加工中的重要性。喷水织机因其用水处理问题而受到环境的制约。喷水织机是水资源消耗较大的产业但并不是污水排放量大的产业,在全行业的努力下,已经实现了喷水织机的废水治理与中水回用。在工信部发布的2015年工业转型升级重点项目指南的通知中,将喷水织机中水回用     

中国长丝织造协会副会长兼秘书长 王加毅：装备企业应密切沟通下游用户

目前,我国长丝织造行业的发展存在着一定困难,表现为产能相对过剩、库存增加、利润减少、资金紧张等,企业发展的差距也比较明显：一方面,优秀的企业日子并不难过,有的企业利润率甚至可以达到10%;另一方面,有些企业已经进入发展怪圈,一味模仿别人的产品和发展路子,这类企业找不到市场,甚至常年处于亏损状态,日子非常难过。在长丝织造行业的转型升级过程中,装备制造是不可或缺的一个重要环节。

SEROLOGIC IDENTIFICATION OF SPECIES OF ORIGIN OF SAUSAGE MEATS

SUMMARY: A partially purified immunoglobulin G (lgG) solution prepared from the serum of species to be tested was heated to the specifications for sausages. The resulting supernatant fluid was decanted and the precipitate washed with saline and used to immunize rabbits. The supernatant fluid was used to sensitize tanned sheep red blood cells. The immune serum was rendered monospecific by absorptions with heterologous, heated lgG precipitates. A sample of monospecific immune serum was absorbed with a washed homogenate of sausage. Aliquots of the monospecific immune serum, both untreated and sausage absorbed, were tested with cells sensitized with the homologous heated lgG supematant fluid. A significant reduction of titer by sausage absorption indicated that the sausages contained the meat homologous to the immune serum.     

BASIS OF STABILITY OF AMINE SALTS OF LINOLEIC ACID

SUMMARY— The mechanism and generality of the known stabilization against autoxidation conferred on linoleic acid by certain basic amino acids, such as lysine and arginine, was investigated. Basic amino acids were the only class of compounds found to confer the effect. However, the smallest basic amino acid, 2,3-diaminopropionic acid, was not effective, nor was αβω-diaminc acid, 3,6-diaminohexanoic acid, although a simple isomer of lysine. The stabilization was observed only in the solid phase. Inclusion of sodium chloride in the solid matrix was deleterious to the effect. A large number of physical and chemical observations were made and correlated but it has not been possible to draw detailed conclusions about the mechanism of stabilization, nor can a detailed structure of the stabilized complex be suggested. The cause of the phenomenon appears to be closely associated with the physical arrangement of the ions in the crystal lattice.

STABILITY OF AQUEOUS EMULSIONS OF THE ESSENTIAL OIL OF HOPS

Hop oil emulsions prepared from different varieties of hops have been found to exhibit enhanced physical stability on the addition of blends of the emulsifiers Span 20/Tween 80 or Span 60/Tween 60. Examination of the particle size and volume distributions of an emulsion by use of a Coulter Counter was found to be an excellent method of monitoring its stability. An indication as to the relative efficiency of emulsifiers can be obtained from Coulter Counter measurements on hop oil emulsions after storage for 4 days. The use of an ultracentrifuge provies a rapid means of testing emulsion stability and hence the effectiveness of emulsion stabilizers.     

EFFECTS OF TYPES OF FAT AND OF RATES AND TEMPERATURES OF COMMINUTION ON DISPERSION OF LIPIDS IN FRANKFURTERS

ABSTRACT— The effect of time, temperature and rpm of comminution of emulsions was determined on the dispersion of approximately 25% of beef fat, pork fat or cottonseed oil in frankfurters. The numbers of lipid particles 5 μ or less in diameter increased in frankfurters containing either beef or pork fat as comminution was continued to higher temperatures, with pork fat dispersed more thoroughly. Fat tended to separate from frankfurters containing beef fat in particles 200 μ or more in diameter. In contrast, no specific degree of dispersion of particles 5 μ or less in diameter consistently indicated emulsion stability, or its lack. Increased rpm during comminution produced an increased dispersion of beef or pork fat. Under the same conditions pork fat was dispersed more finely than beef fat. Dispersion of cottonseed oil produced finely dispersed particles beyond the resolution of light microscopy, as was confirmed by electron microscopy which showed a substantial number of particles to be less than 1 μ in diameter.     

DEVELOPMENT OF CHAINS OF CELLS OF SACCHAROMYCES CEREVISIAE DURING FERMENTATION

The lengths of chains of cells of Saccharomyces cerevisiae were studied during fermentation. Pitching yeast generally contained about half of the total number of cells as two-celled chains. The chain lengths varied during the subsequent fermentation and the variations were characteristic of the strain. Electronic counting assessments of chain length were unreliable.     

ANALYTICAL CHARACTERIZATION OF THE PRODUCTS OF NONENZYMATIC GLYCOSYLATION OF LYSOZYME

The quantitative analysis of the reaction products of the water activity dependent nonenzymatic glycosylation of lysozyme was not straightforward. Difficulties arose in the determination of the number of bound glucose molecules because glycosylation leads to glucose mediated protein aggregation, and the likely presence of a mixture of relatively labile Schiff-base intermediates, and the more stable ketoamine products generated by Amadori rearrangement. Polyacrylamide gel electrophoresis was used to monitor protein aggregation; periodate oxidation, nuclear magnetic resonance (NMR), and oxalic acid hydrolysis combined with HPLC, emerged as the most promising methods to quantitate the degree of glycosylation. Possible interpretations are advanced to explain the apparent discrepancies in degree of glycosylation suggested by the different analytical methods evaluated.
