牛奶蛋白纤维不锈钢长丝包芯纱的研制 总被引:1,自引:1,他引:1
分析用于纺织品中的不锈钢长丝的表面形态及力学性能。介绍了不锈钢丝牛奶蛋白纤维包芯纱的纺纱装置、工艺流程及原理。并对5种不同特数、不同不锈钢丝含量包芯纱力学性能、纵向形态及毛羽指数等进行对比分析。结果表明:将不锈钢长丝与牛奶蛋白纤维做成包芯纱用于设计电磁屏蔽面料是可行的。既有牛奶蛋白纤维的舒适性,又具有防电磁辐射的功能。与纯牛奶蛋白纤维纱比较,其断裂强度随不锈钢丝含量增大而减小;断裂伸长在不锈钢丝含量30%以内时,降低不明显,30%以上时明显减小。成纱2 mm、3 mm毛羽数高于纯牛奶蛋白纤维纱。 相似文献

The use of whey protein concentrate (WPC) for the improvement of physical properties of nonfat fermented milk drink was investigated. Drinks were prepared from nonfat milk powder and WPC at different proportions. Rheological properties, serum separation and particle size of the drinks were measured. The effect of WPC on the physical properties of the drinks was evaluated by comparison with those of commonly used stabilizers, including propylene glycol alginate and locust bean gum. WPC addition caused an increase in the consistency coefficient and thixotropy and a decrease in the particle size of the samples. There was no serum separation in the sample with 2% WPC. Large unstable aggregates were observed in the sample with 3% WPC, which also exhibited the highest serum separation. WPC up to a level of 2% positively influenced the physical properties of nonfat fermented milk drink similar to stabilizers.
Fermented milk drinks are consumed especially for their beneficial health effects. Physical properties of fermented milk drinks influence their quality and consumer acceptability. Hydrocolloid stabilizers are used for the improvement of physical properties of fermented milk products. Whey protein concentrates (WPC) with high protein content can be used to substitute hydrocolloid stabilizers. In this study, the effect of the addition of WPC with 75% protein in place of a part of the nonfat milk powder on the physical properties of nonfat fermented milk drink with 6% dry matter was investigated. Use of an appropriate level of WPC was found to be important for obtaining a desirable effect on the physical properties of nonfat fermented milk drink. The effect of WPC was found to be comparable to those of commonly used hydrocolloid stabilizers. Use of WPC also enhances the nutritional value of the product as whey proteins have a high biological value. 相似文献

The rheology and the microstructure of emulsions stabilized with milk protein concentrate (MPC) were investigated using different MPC and oil concentrations. Steady‐shear tests showed that the emulsions were Newtonian at low oil concentrations (<20 wt%), whereas they were pseudoplastic and thixotropic at high oil concentrations (>20 wt%). Dynamic rheological measurements demonstrated that these emulsions behaved as weak gels, as indicated by relatively high values of G′ to G″. The rheological behavior of these emulsions was consistent with bridging flocculation mechanisms, whereby more than one droplet is shared by adsorbed casein aggregates/micelles. This was confirmed by confocal microscopy, which showed that these emulsions were aggregated. 相似文献
