Ultrasonic is often used for laundering. However, it is proved by both experiments and theoretical analyses that ultrasonic can also push particulates into fabric under certain conditions. In this paper, wool fabric was simulated by porous filtration membrane with the aperture of 0.15 μm. The membranes were placed on the set with three different distances from ultrasonic transducer, affected by five different hydraulic pressure grads and ultrasonic fields with frequency of 28kHz and 40kHz,respectively. Measuring the penetrability and comparing the data with that measured without the effect of ultrasonic. It was proved that the penetrability of porous material can be enhanced by ultrasonic, and the enhancement was determined by ultrasonic frequency, distance between membrane and transducer and hydraulic pressure. According to Hagon-poiseuille formula and kinematics model of pore wall in ultrasonic field, it is known that the increase of liquid flux through porous material can push much more particles into it. Finally, nano wool fabric was produced by ultrasonic, and the accuracy of our view can be seen from its scanning electronic microscope.

Corona discharge is a popular technology which is mainly applied in modifying the surface of material. In this paper, the pre-heating process was augmented before corona discharge, which mainly improved the efficiency of corona discharge. The surface hydrophilic properties of wool fabric, with and without pre-heating, which were treated with the same corona discharge, were different and the former was better. Enhancing the pre-heating temperature and corona discharge voltage can increase the hydrophilic properties but the high temperature make fabric yellow. Corona discharge combined with pre-heating treatment can get good hydrophilic effect and the water absorption time was less than 1 second. But the thicker one should increase voltage and temperature, and then the water absorption time can be less than 1 second.

This paper discusses the features of the distribution of wool fabrics′ pores, tests and quantitatively analyzes the pores and structures′ effect on the permeability properties. The result proves that the distribution of pore size has a wide range from small to big with the asymmetry of peak value towards left, and inter-fiber′ pore and inter-yarns′ pore have a relatively obvious boundary. The pore′s size has a significant correlation with permeability. Also the permeability have the same significant correlations with thickness、tightness and average float of the wool fabrics.

This article describes the synthesis of some novel coumarin compounds to use as acid dyes by using compounds 1 - 4 as starting materials, which were prepared by interaction of 2-hydroxybenzaldehyde with ethyl 3-oxobutanoate, diethylmalonate, 4-nitrobenzenediazonium chloride and 4-sulfobenzenediazonium chloride, respectively. Compound 1 reacted with bromine and 2-cyanoacetohydrazide to give phenacyl bromide derivative 5 and 2-cyanoacetohydrazone derivative 6, respectively. Coupling of compound 6 with equimolar amount of 2-sulfo-4-((4-sulfophenyl) diazenyl)benzenediazonium chloride gave coumarin acid dye 8. Phenacyl bromide derivative 5 re-acted with potassium cyanide in refluxing ethanol to produce compound 7, which on coupling with equimolar amount of 8-hydroxy-6-sulfonaphthalene-2-diazonium chloride and 8-hydroxy-3,6-disulfonaphthalene-1-diazonium chloride gave coumarin acid dyes 9 and 10, respectively. Interaction of compound 2 with 2-amino-5-((4-sulfophenyl)diazenyl)benzenesulfonic acid, benzene-1,4-diamine and 3,3’-dimethoxy-[1,1’-biphenyl]-4,4’-diamine in refluxing ethanol afforded compounds 11, 12 and 14, respectively. Diazonium sulphate of compounds 12 and 14 coupling with 4-amino-5-hydroxynaphthalene-2,7-disulfonic acid gave compounds 13 and 15, respectively. Cyclocondensation of compound 3 with ethyl 3-oxobutanoate, diethyl malonate and malononitrile afforded derivatives of 3-acetyl-2H-chromen-2-one 16, ethyl 2-oxo-2H-chromene-3-carboxylate 17 and 2-imino-2H-chromene-3-carbonitrile 18, respectively. Reaction of sodium benzenesulfonate derivative 4 with ethyl 3-oxobutanoate and hydrazine hydrate gave compounds 19 and 20, respectively. The structures of the newly synthesized compounds were confirmed by elemental analysis, UV/ VIS, IR, 1H NMR and Ms spectral data. The suitability of the prepared dyestuffs for dyeing of wool and silk fabrics has been investigated. The dyed fabric shows good light fastness, very good rubbing, perspiration, washing and excellent

In order to improve the accuracy of using visual methods to detect the quality of fluff fabrics,based on the previous research,this paper proposes a method of rapid classification detection using support vector machine(SVM).The fabric image is acquired by the principle of light-cut imaging,and the region of interest is extracted by the method of grayscale horizontal *** obtained coordinates of the upper edge of the fabric are decomposed into high frequency information and low frequency information by wavelet transform,and the high frequency information is used as a data set for *** experimental comparison and analysis,the detection rate of the SVM method proposed in this paper is higher than the previously proposed back propagation(BP)neural network and particle swarm optimization BP(PSO-BP)neural network detection methods,and the accuracy rate can reach 99.41%,which can meet the needs of industrial testing.

This paper investigates the method of extraction of coloring matters from yellow chrysanthemum flower and its dyeing properties on wool fabrics. The investigation shows that the coloring matters in yellow chrysanthemum flower can be extracted by boiling water. The extracted dye solution is yellow and stable at pH 3, while its color changes from yellow to yellow-green when pH is 9. The wool knitted fabric, which is dyed under the optimized dyeing conditions with the extracted dye from yellow chrysanthemum flower, shows that the color of bright yellow and its color fastness properties are acceptable. Yellow chrysanthemum flower can be served as the resource of the natural plant dyestuff for wool fabrics.
