POE-g-GMA, PP-g-GMA and EVA were used as the compatilizers for PP/ TPEE blends, the dynamic rheological and phase behaviors of which were investigated by rotary rheometer. The experimental results showed that the complex viscosity, storage modulus and loss modulus for PP/TPEE/EVA blend were the lowest. Calculated from time-temperature superposition (TTS), the temperatures of phase separation for PP/TPEE, PP/TPEE/POE-g-GMA and PP/TPEE/PP-g-GMA were 220, 230, 240 and 250℃ respectively, the applicable frequency range of which were above 1.32, 0.15, 1.12 and 2.82 respectively. It was very obvious for the phase separation phenomena after the addition of EVA in blends, while the addition of POE-g-GMA improved the compatibility for the blends. The results of cole-cole curves were consistent with that of TTS curves, which were more accurate than TTS method.

This paper attempts to adopt enzymatic approach to remove the skin crumbs from cashmere, since the skin crumb is a long-standing problem not fundamentally solvedover the years in cashmere dyeing. Three biological enzymes-cutinase, pepsin and protease were sdlected and applied to the treatment of skin crumbs searately.The effect of skin crumbs removal was investigated and the individual process conditions were examined. The fiber damages of the cashmere before and after treatment were compared. The results showed that the skin crumbs removal rate reached 29% when T. fuscacutinase was used in the treatment of skin crumbs under the conditions: amount of T. fuscacutinase 8 mL/g, pH=8.0 , temperature 60°C , time 5 h ,and liquor ratio 1:50 .The removal rate was 17% in the case of pepsin under the conditions: pH=2.2, temperature 4 °C ,amount of pepsin 6% (o.w.f), time 6 h, and liquou ratio 1:50. And the removal rate was up to 46% in the case of protease Savinase 16 L under the conditions: amount of Savinase 16 L, 1 mL/g, pH=8.5, temperature 45°C, time 4 h, and liquor ratio 1:50. The experimental results revealed that cutinase and pepsin caused only slight damage to the treated fiber whereas protease led to serious fiber damage. Therefore, the former two kinds of enzymes may be used in the treatment of cashmere for removing skin crumbs. The enzymatic method can partially remove the cashmere skin crumbs, so it is necessary to make further study.

In this paper, PET/PP and feather fibers/PP scattered composite melt-blown material were made by scattered composite melt-blown process, respectively. The influences of the thickness, basis density and average fiber diameter on the sound-absorbing property of the materials were studied. It is found that the sound absorption coefficient increases with the increase of the thickness. The influence of basis density on the absorption coefficient is not as obvious as the thickness. The average melt-blown fiber diameter in 1.7~2.4μm has no obvious impact on the absorption coefficient. In addition, the sound-absorbing material made by 3M and the traditional waste fiber sound-absorbing material were selected to compare the sound-absorbing property. It indicates that the sound-absorbing coefficient of PET/PP scattered composite melt-blown sound-absorbing material is similar to 3M Company's product, which is better than the traditional waste fiber sound-absorbing material and feather fibers/PP scattered composite melt-blown nonwoven material

For solving these problems, a flexible touch device is developed based on capacitive principle and made of a single layer non-woven carbon film. Within a working area of 128mm×72mm in the touch pad with L-shape electrodes, of which the length of each side is 72mm, the test results show that the linearity of the touch device in X and Y directions is ?1.40% and ?2.39%, respectively, and the resolution reaches as high as 251dpi×243dpi. To discuss more on controlling accuracy of the device, the deviation rate is defined. The test results shows that, the control positions whose deviation rate is greater than 6% are located near the edges of the work area. In addition, to increase the side length of L-shape electrodes has positive but minor effects to improve linearity. Therefore, it would be better to apply point electrodes to the touch device for flexibility and portability.

To solve the problem of detecting foreign fiber in the textile enterprises, a technical solution was put forward in which a single green modulated light and three silicon photocells regularly arrayed were adopted. It can detect foreign fiber and yarn faults by means of contrasting the reflection and transmission signals received by the silicon photocells and analyzing the color and diameter change of yarn. The mathematical model was established, and the simulation experiment was done based on H∞ filter using software MATLAB. The results proved that the algorithm was more sensitive to signal singularity of the surface brightness signal and the diameter signal of yarn, which can also track the percentage change in color. It is further confirmed that the scheme of detecting foreign fiber and yarn faults is feasible, the H∞ filter algorithm can effectively improve the detection precision to foreign fiber and yarn faults.

When cotton comber is carding at high speed, fibers damage and breakage would be caused by its cylinder carding, which influences on the combing quality. Therefore, this paper aiming at the cotton fiber breakage, constructs the theoretical velocity model of cotton comber on the condition that the cotton fibers are not ruptured, and also calculates the maximum theoretical velocity of cotton comber, namely “flexible combing value”. This theoretical velocity model considers the average carding force of single fiber in the process of combing as well as the breaking strength of cotton fiber. Based on the theoretical analysis, this paper also verifies the accuracy of theoretical velocity according to amount variation of short fibers between before and after the cylinder combing, and proposes the concept of “flexible combing ratio”. This study will provide a theoretical foundation for the development of new type of high-speed cotton comber and its carding part both with high-quality combing.
