The aroma sustained-release cotton fabric was prepared by finishing rose fragrance nanocapsules directly on cotton.The structure and properties of nanocapsules were demonstrated by transmission electron microscope(TEM),dynamic light scattering(DLS),fourier transform infrared spectrometer(FTIR),X-ray diffraction (XRD),gas chromatography-mass spectrometry(GC-MS)and electronic nose.The results showed that the spherical nanocapsule dispersed evenly and the average diameter kept 51.4 nm.The existence of COO peak(1741 cm? 1)in the FTIR curve of the finished cotton fabric and the decrease of crystallinity demonstrated that rose fragrance nanocapsules have been incorporated into the cotton fabrics.The washing resistance of the cotton fabrics finished by 51.4 nm nanocapsules was much better than that by rose fragrance alone.Besides,the loss of fragrance from the cotton fabrics finished by 51.4 nm nanocapsules was obviously lower than that by 532 nm nanocapsules and rose fragrance.The smaller the nanocapsule size,the better the sustained release property.Electronic nose analysis also displayed that the aroma released from the cotton fabrics finished by nanocapsules after washing has no obvious variety in contrast to that without washing.The cotton fabrics finished by nanocapsules has the excellent sustained release property.  相似文献

以植物还原剂——金银花提取物和化学还原剂——丙三醇,分别还原硝酸银,制备了两种纳米银溶液。采用浸渍法将上述制备的纳米银溶液分别对棉织物进行功能整理。利用SEM、EDS、XRD、FTIR分析整理前后棉织物的外观形貌及结构,并探讨了整理后的棉织物的抗紫外性能、不同洗涤次数后其含银量、色差和抗菌性能的变化。结果表明,纳米银粒子主要通过范德华力吸附在棉织物纤维素的无定形区;与化学还原法相比,植物还原法制备的纳米银粒径减小了约15nm,植物还原法制备的纳米银溶液整理后的棉织物经过50次洗涤后,棉织物表面的纳米银吸附量及色差变化不大,且对大肠杆菌和金黄色葡萄球菌的抑菌率仍旧达到99%以上,具有优异的抗菌性及良好的耐洗涤性能。另外,植物还原法制备的纳米银溶液整理后的棉织物紫外线防护系数(UPF)值达到了36.82,具有较好的抗紫外性能。  相似文献

For many purposes the natural-synthetic fiber-blend fabrics are more suitable than pure natural or synthetic products. It is often possible to obtain a maximum in clothing and textile technical properties by compensating the defects of one fiber by using an other totally different fiber. Many problems, however, have arisen in the production of flame-retardent fabrics because the use of synthetic fibers often makes the fire retardancy less effective. In our 2-year research project different fire-retardant (FR) viscose–polyesters fabrics were prapared at first in the laboratory scale. The natural type raw materials were Modal Prima viscose and normal FR–viscose cotton type staple fibers. The synthetic raw materials were FR–polyesters of the same type with two different flame retardants. Test fabrics were knitted in the laboratory by using seven blended yarns in the ratios 100/0, 80/20, 65/35, and 50/50 and vice versa. Cotton type PVC–fiber was also used in some experiments. All these test fabrics were also finished chemically by using normal crease-resistant (DMU, DMEU, DMDHEU, and TMM) and flameretardant (N,-methylolphosphonopropionamide and THPC) finishing chemicals. The textile and fire-retardant properties of the original and finished fabrics were estimated by using addon, tensile strength, LOI-value, and vertical flame test determinations. The mechanism of flame retardancy was also studied with DSC technique, P- and N-analysis and char investigations. The test results of viscose/polyester studies were compared with the results of cotton/polyester studies. After laboratory studies the best methods for FR–viscose/polyester fabric production were chosen, and the fabrics were manufactured. The fabrics were home-washed 20–50 times, and the textile and FR-properties were determined after each 10 washings. These results were again compared with results of cotton/polyester fabrics.  相似文献

以植物金银花提取物作为还原剂制备了纳米ZnO和纳米Ag,通过浸轧法将纳米ZnO单独整理以及将两者依次整理到棉织物上制备多功能棉织物(ZnO-棉织物、ZnO/Ag-棉织物).利用SEM、XRD、FTIR分析了整理前后棉织物的形貌和结构,并探讨了整理后棉织物的多功能性.结果表明,棉织物上的纳米粒子分布较均匀且发生了轻微团聚.与ZnO-棉织物相比,ZnO/Ag-棉织物对亚甲基蓝(MB)和红酒的降解率分别提高了7.09%和10.61%,说明纳米Ag提升了纳米ZnO的光催化活性.ZnO-棉织物经过10次洗涤后其纳米粒子含量虽有小幅下降,但对MB的降解率仍达到83.24%以上,说明负载纳米粒子后棉织物具有良好的自清洁能力和耐洗性能.此外,ZnO-棉织物和ZnO/Ag-棉织物的紫外防护系数(UPF)值分别达到33.23和41.06,对大肠杆菌和金黄色葡萄球菌的抑菌率均达到95%以上,表现出优良的抗紫外线性和抗菌性能.  相似文献

A novel cyclic-shaped multifunctional copolymer named poly[tetra(tetramethylcyclosiloxyl-piperazin)-phosphinic acid methyl ether] (PNCTSi) was successfully synthesized. Its flame-retardant and hydrophobicity properties on cotton fabrics were investigated. The limited oxygen index (LOI) value of treated cotton fabrics with PNCTSi was up to 29.8%. By vertical burning test, it was found that the treated cotton fabrics have no after-flame and no after-glow. Apparently, more amounts of char were generated and hazardous volatiles distinctly reduce after combustion by thermogravimetric analysis. Besides, Treated cotton fabrics with PNCTSi can give a hydrophobic property, which reach a contact angle of 150°. The surface morphology of treated cotton fabric before and after combustion was analyzed by scanning electron microscopy, after burned, the surface morphology of cotton fiber exhibited more smooth and expanded feature. After washing the cotton fabric for 20 times, the LOI remains at above of 26.0%. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136, 47280.  相似文献

There is a global demand for constant increase in the production of textile fibres. Currently, the market for cellulosic fibres is dominated by cotton and viscose fibres. However, new alternative cellulosic fibres are being sought to meet the growing demand. The dyeing properties of novel fibres aiming at the marketplace are among the properties that determine their applicability to textiles. Recently, a novel process for producing cellulosic fibres, the Biocelsol process, has been scaled up so that the spinning of yarn from Biocelsol fibres is now possible. In this study, the reactive dye Levafix CA Blue was applied to cellulosic fabrics made from viscose, cotton, and Biocelsol yarns. The crystalline structure and morphology of the fibres were studied by Fourier transform infrared spectroscopy and field‐emission scanning electron microscopy. The crystalline structure and morphology of the Biocelsol fibres resembled those of viscose fibres, but, owing to higher water absorption, the Biocelsol fabric had a higher dye exhaustion. The colour yield of the Biocelsol fabric was 62% and 41% higher than that of cotton and viscose fabrics respectively, suggesting that less dye is needed to gain a shade in Biocelsol fabric than in viscose and cotton fabrics.  相似文献

Commercial microencapsulated photoresponsive dye was applied on cotton, polyester/cotton and polyester fabric using a pad‐dry‐cure process. Colour fastness of the photoresponsive fabrics to washing, wet cleaning, dry cleaning, rubbing and light was investigated. The CIELAB colour values of the fabrics before and after testing were measured using a reflectance spectrophotometer, and the colour differences were calculated to evaluate the fastness properties. The fabrics had better colour fastness to wet cleaning and washing than to dry cleaning. The fabrics showed higher colour fastness to wet than to dry rubbing. The photoresponsiveness of the fabrics decreased with prolonged exposure time to artificial light due to low photostability of the microcapsules.  相似文献
