In order to further clarify the key factors affecting the performance of natural fiber flexible actuators, four kinds of fibers with excellent hygroscopic properties, cotton fiber, alginate fiber, viscose fiber and wool fiber, were used as raw materials to prepare a spiral coil structure blended yarn actuator by twisting method. The contraction ratio and work capacity of the actuator were tested by a self-made wet stimulation actuator platform. The actuator performance of stretch responding with wet stimulation prepared from blended yarn was evaluated. Univariate analysis of variance and Plackett-Burman test were designed to study the effects of each factor. The test results show that compared with pure cotton yarn, the actuator contraction ratio of viscose fiber/cotton blended yarn and alginate fiber/cotton blended yarn increases from 11.8% to 21.8% and 20.0% respectively. Compared with wool yarn, the contraction ratio of wool/viscose fiber blended yarn increased from 17.55% to 28.00%. Yarn type, coil number and twist have significant effects on contraction ratio, while load mass, coil yarn number and yarn type have significant effects on work capacity. [ABSTRACT FROM AUTHOR]

Since the industrial revolution the uncontrolled production and living activities of human society have brought about various adverse effects on the global environment among which the most urgent threat to human beings comes from climate change caused by the greenhouse effect. The Paris Agreement which marks the agreement of all countries on low-carbon transition aims to limit the global temperature increase to 2 ℃ in this century while seeking measures to further limit the temperature increase to 1. 5 ℃ and in response countries around the world are actively exploring low-carbon strategies and planning carbon reduction pathways. The goal of achieving carbon neutrality by 2060 is a requirement for all industries in China to develop corresponding carbon-neutral pathways as soon as possible. Carbon neutrality means that the carbon emissions from all activities within the selected system boundary can be offset with the carbon absorbed through natural or artificial means i. e. the carbon footprint is zero. There are photosynthetic and soil carbon sequestration activities during natural fibers' raw material acquisition stage which may be of some value to the carbon neutrality of the textile and apparel industry. However because the biochemical reactions involved in this stage are more complex compared to industrial processing operations there are still divergent opinions on the methods of accounting for its carbon footprint which brings obstacles to the evaluation of the carbon effect of natural fibers in the raw material acquisition stage and even in the whole life cycle. To grasp the progress of research on the carbon effect of natural fibers in the raw material acquisition stage and analyze the existing problems so as to help promote a more accurate and comprehensive carbon footprint accounting and carbon effect evaluation of natural fibers cotton hemp silk and wool are selected as the research objects and the current situation of carbon effect evaluation of the above four typical natural fibers in this stage is discussed by defining the scope of the raw material acquisition stage of natural fibers. The analysis of the literature shows that the research on the carbon absorption of natural fibers is insufficient compared with the research on carbon emission at the stage of raw material acquisition and the following points can be improved in subsequent related studies according to this paper i the definition of relevant terminology is not clear ii the accounting results lack comparability due to the inconsistency of the system boundary and accounting methods chosen by the existing research and the quality of production activity data is difficult to be guaranteed iii there are commonalities and differences in the growth characteristics and carbon transfer paths of various types of natural fibers at the stage of raw material acquisition and a universal theoretical model has not yet been concluded for this point iv the influence of the time factor on the results in carbon footprint accounting has not yet been agreed. In response to the above problems this paper compares the international standards and reports with high recognition in recent years and standardizes a section of terms for the study of carbon effect in the raw material stage of natural fibers then the carbon transfer pathways of two major classifications of natural fibers i. e. cellulose fibers and protein fibers are summarized in this stage which provides references for building theoretical models in addition the influence of time factors on the evaluation results of carbon effect is discussed in terms of the time boundary of the global warming potential GWP and the short-term carbon storage time of natural fiber garments. Exploring the carbon neutral path in the textile and apparel industry requires both verifying the industry's carbon emissions as well as recognizing the industry's carbon absorptions and trying to offset carbon emissions with natural carbon sinks to reduce carbon neutral costs. This paper discusses some of the problems and solution ideas for the evaluation of carbon effect at the stage of natural fiber raw material acquisition which can provide a reference for improving the carbon footprint accounting at this stage and help achieve a more comprehensive and accurate assessment of the carbon effect of natural fibers.

To make full use of the resource-rich domestic kapok fiber and turn waste into wealth, the kapok fruit, fiber morphology and oil sorption abilities of Quanzhou kapok were studied in comparison with Indonesia kapok. Comparing to Indonesia kapok, Quanzhou kapok has the similar fruit shape and internal structure. The fiber length of Quanzhou kapok is concentrated in 14.5-27.5 mm which is slightly shorter than Indonesia kapok fiber, but the length distribution is more uniform; the fiber fineness centers around 15-35 µm. Epidermis wax mass fraction of Quanzhou kapok fiber was about 1.660%. The average oil sorption capacity of Quanzhou kapok fiber assembly in soybean oil is 41.05 and the average retention rate is 97.48%. The average oil sorption capacity and retention rate in engine oil is 37.85 and 97.97% respectively, higher than that of Indonesia kapok. Kapok fiber assembly could be recirculated fewer than SIC Times for better oil-absorption. The result show that Quanzhou kapok fiber has more excellent oil-absorption ability and can be used as oil-sorbing material. [ABSTRACT FROM AUTHOR]

The natural plant fiber has a large molecular weight and complex structure and composition，and its thermal cracking products and the composition distribution are also more complex. The fast pyrolysis- comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry（Py-GC×GC-TOF/ MS），thermogravimetry-Fourier transform infrared spectroscopy（TG-FT-IR），and in situ Fourier transform infrared spectroscopy（in situ FT-IR）methods were used to study the thermal pyrolysis process of six different natural fibers. The distribution of thermal pyrolysis products of different fibers under different pyrolysis temperatures was investigated and the product form was fully discussed. The research results show that the products of fiber pyrolysis mainly include alcohols，aldehydes，ketones，acids，esters，hydrocarbons， dehydrated sugars and CO2，etc. The types of pyrolysis products of different natural plant fibers are obviously different，and the main product types obtained are all different. At the same time，the results of in situ infrared spectroscopy and mass spectrometry show that pyrolysis products are closely related to the pyrolysis temperature. The results of in situ infrared experiments show that when the pyrolysis temperature is lower than 100 °C ，the adsorbed water on the surface of the fiber structure is desorbed，but the fiber structure does not change significantly. When the pyrolysis temperature range is 100~200 °C ，the temperature has little effect toward the pyrolysis process. When the temperature exceeds 300 °C ，the fiber pyrolysis reaction intensifies and the surface structure changes significantly，and the main products are aldehydes and ketones. [ABSTRACT FROM AUTHOR]

The buckling analysis of natural fiber reinforced (NFRC) cylindrical shells was performed based on Reissner’s shell theory and the symplectic approach. The governing buckling equations for axially-compressed NFRC cylindrical shells were established in the Hamiltonian system. Therefore, the original problem was reduced to a symplectic eigenproblem in the symplectic space. Accurate critical loads and analytical buckling mode shapes were directly obtained from the symplectic eigenvalues and eigensolutions. With numerical examples, the effects of hygroscopic aging on the expressions of eigensolutions were investigated. In addition, the influences of the aging time, the fiber content and the geometric parameters on the buckling behavior of NFRC cylindrical shells were discussed in detail. [ABSTRACT FROM AUTHOR]

The surface properties of three plant dyed modal fiber were studied. Modal fibers were dyed by three plant dyes. Then the fiber were separately analyzed by scanning electron microscope, static electricity and surface solid elements. The test results showed that there were solid particles on the surface of dyed fibers. The overall friction coefficient and mass specific resistance of the three plant dyed modal fibers were all much larger than those of modal fibers with natural color. The larger the surface attached particles on the surface of plant dyed modal fibers, the bigger the overall friction coefficient of fibers were. It is considered that the static electricity property and friction property are affected by the solids on the surface of plant dyed modal fibers, which results in the entanglement phenomenon during the production. The health treatment is needed to improve the spinnability. [ABSTRACT FROM AUTHOR]

In recent years, there has been increasing interest in the use of natural fiber reinforced polymer in many fields due to low density, high specific strength and eco-friendly property. However, the application of composites is faced with difficulties in outdoor environment, such as water absorption, degradation, low mechanic strength and dimensional stability. In order to improve the aging-resistant property of flax fiber fabrics/basalt fiber fabrics reinforced UP (unsaturated polyester resin), the author used the artificial simulating climate box (ultraviolet and condensation) to accelerate ageing process of HCM (hybrid composite materials), which was composed of different sandwich layers and included H1, H2 and H3 representing basalt fiber content of total fibers of 20.3%, 41.5% and 63.7%, respectively. Mechanical properties, DMA (dynamic mechanical analysis) performance and microstructure of HCM were affected by basalt fiber content and aging time. The result showed that both flexural strength and impact strength first increased and then decreased with aging time. The retention of flexural strength was 62.5%, 58.1% and 57.0% for H1, H2 and H3, respectively. With regard to impact strength, the figures were 66.8%, 66.7% and 53.2% for H1, H2 and H3, respectively. The results of ANOVA (analysis of variance) and LSD (least-significant difference) illustrated that ultraviolet aging time had significant effects on flexural strength of H3 (P<0.05) while basalt fiber content had not significant effects on flexural strength retention (P>0.05). As ultraviolet aging time increased, rigidity and frangibility of HCM increased gradually. The poor interfacial adhesion was demonstrated between flax fiber and UP by DMA. The result of SEM (scan electron microscope) indicated a poor interfacial adhesion between flax and UP matrix, such as debonding and more voids. However, basalt fibers and UP matrix were combined closely and matrix fragments around basalt fibers were found. The main reason was that hydrogen bond produced after absorbing water destroyed the interface between flax fibers and UP matrix. So process of water damage in the interface was verified by SEM. In conclusion, mechanical properties of HCM increase slightly owing to further solidified substrate. However, with the extension of aging time, irreversible hardening happens to matrix, followed by micro-crack appearing between fiber and matrix, which leads to a decrease in mechanical properties of HCM. In addition, water has significant effect on flax fiber and the mechanism of water damage is approved by SEM results. The manufacture of HCM by using natural degradable fibers is meaningful to environmental protection; on top of that, it can provide the reference to aging-resistance improvement of inorganic fibers/plant fibers reinforced polymer HCM.
