Leather industry is facing the consequences of their historic lack of communication and now are under an increasing pressure to communicate their position and policies with regards to corporate social responsibility (CSR), informing consumers about the corporations’ good intentions and actions to recover clarity and be able to affirm without doubts that responsibly manufactured leather is sustainable. Under this context, this paper aims to examine CSR communication in the leather sector on Twitter identifying the main topics of CSR and the main participants in the creation of content and thus contribute to the development of CSR strategies for the leather industry. A software framework has been implemented in order to manage big text data in the study of CSR and sentiment computational content analysis to classify the tweets as positive, negative, or neutral. The results show that the general public associates leather with the environment, sustainability, and fashion. The general opinion about the leather industry’s CSR is rather neutral. Nonetheless, negative opinions occupy a close second place, and positive opinions are rare. Lastly, alternative bio-materials sneak in the industry reshaping the opinions to more positive ones.

This study presents an analysis of the possible use of a viscose rayon (CV) fiber from textile industry wastes to develop a reinforced cementitious composite as an alternative for textile discharge valorization. Several techniques were used to characterize precursor fibrous waste material such as SEM, FT-IR, DSC, and TGA. The experimental studies were conducted based on a conventional cementitious mortar (control) and four different fiber contents (0.5, 1, 2, and 4 wt%). For mechanical behavior analysis, uniaxial compressive strength tests were carried out at different ages (7, 14, and 28 days after production). The results showed favorable CV fiber addition as reinforcement up to a maximum limit. The optimum concentration of fiber was 0.5 wt% (FRC0.5), which provided 28 days of higher compression strength. The addition of CV waste as reinforcement in cementitious matrix resulted in an improved compressive strength above 20.6% compared to the conventional non-reinforced mortar. Furthermore, CV fiber addition improved the ductile behavior of the new composite allowing a controlled failure, even after maximum rupture loading.

The influence of different tire skeleton structural parameters on tire grounding characteristics was investigated. Using a 225/60R18 100H radial tire as the research object, the experiment and simulation were carried out by changing the diameter of the belt steel wire, the angle of the belt layer, and the number of carcass plies. Using the model parameters obtained from the rubber physical test, the finite element model of the tire was created in Abaqus for static loading simulations, the relevant data such as tire pattern impression and sinkage were analyzed, and the validity of the model was investigated. The influence of skeleton material on tire structure was deduced by determining the amount of stored strain energy of tire. The results showed that the belt angle in the grounding area had the greatest influence on the belt stress and presented a second-order change. However, the number of carcass cord layers and the diameter of the belt steel wire had little effect on the corresponding skeleton stress. The number of carcass layers had the greatest influence on the stored strain energy of the tires. The diameter of the bundled steel wire and the angle of the bundle had little influence.

With the rapid development of modern science and technology, a kind of invisible pollution named electromagnetic radiation has increasingly attracted the attention of all sectors of society. Therefore, electromagnetic shielding protective clothing is widely used by people for daily life and work. More and more scholars and researchers are paying attention to this research direction, and they have done a series of related research on how to improve the electromagnetic shielding effectiveness of clothing materials. At the same time, the related comfort properties of these clothing materials should also be concerned because they will greatly affect the wearer’s experience. This study evaluated the related comfort properties of a kind of copper-plated nonwoven materials with different electromagnetic shielding effectiveness, including air permeability, water vapor permeability, and thermal resistance. The result shows that electromagnetic shielding effectiveness is positively related to the amount of plated copper based on this kind of copper plating method. Other experiment results display that air permeability and water vapor permeability of this kind of material are negatively related to its electromagnetic shielding effectiveness. On the contrary, their thermal resistance is positively related to their electromagnetic shielding effectiveness. In addition to the above, it also found that air permeability and water vapor permeability have a positive correlation with optical porosity, and thermal resistance has a positive correlation with volume porosity.

Currently, industrial winding processes are often optimized by trial and error. A digital twin of winding processes could be helpful in order to assist industry to optimize the winding processes. Formulating the kinematic equations that form the basis of such a simulation of the winding process is straightforward in principle. However, a major challenge is to model the increase of the package diameter as a function of time or length of wound up yarn, respectively. In this paper, a kinematic model for the winding process is first outlined. The focus of the paper is the description of a workflow in order to find a model for the package diameter increase dependent on the wound yarn length. For that purpose, a new image analysis method is presented to derive the general class of the model function for the diameter increase. Then, the measurement results of a series of experiments are analyzed to find a parameterization of the model function. Here, the input process parameters winding tension, cradle pressure, winding speed, and traverse ratio are varied at two levels. Finally, the linear regression model for the package diameter increase is presented.

To reduce the environmental pollution caused by medical protective materials, such as masks and protective clothing, biodegradable antibacterial materials have received more and more attention in recent years. In this study, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(butylene-adipate-co-terephthalate) (PBAT) were electrospun together and then treated with nano-TiO2 to develop and evaluate a biodegradable, antibacterial nanofiber membrane for medical protective fabric. The SEM images displayed that the nanofiber membrane with a mass fraction of 13 and a mass ratio of 50:50 PHBV/PBAT had the smallest diameter and the best morphology of all samples. In addition, the mechanical properties test and water contact angle test results demonstrated that the PBAT/PHBV composite nanofiber membrane had better mechanical properties and hydrophobicity without compromising its fundamental structure than pure PHBV. The addition of TiO2 nanoparticles decreased the fiber diameter of this nanofiber membrane. When the TiO2 concentration was 1.0 wt%, the average fiber diameter was 367 nm, which might approach the sub-micron level. Meanwhile, the presence of TiO2 reduced adhesion between fibers of the PBAT/PHBV membrane, resulting in a more uniform fiber distribution. Additionally, the elongation at the break of the PHBV/PBAT/TiO2 nanofiber membrane with 1.0 wt% TiO2 was raised from (135 ± 5)% to (203 ± 2)%. The PHBV/PBAT/TiO2 nanofiber membrane containing 1.0 wt% TiO2 inhibited Escherichia coli and Staphylococcus aureus, and its antibacterial rate was over 98%. In this research, we successfully prepared composite materials that were both biodegradable and antibacterial, which can be applied in the field of medical protection. It can promote the development of protective textile materials in the direction of functionalization and degradation.

Clothing plays a significant role in affecting the performance, comfort, and mobility of human body. However, no study explored the clothing for delivery personnel with improved ergonomic performance. The purpose of this study was to develop a pair of novel work pants to increase the mobility and comfort of delivery personnel. Skin deformation rates of eight university students were measured using surface-painting-line method under various typical activities simulating those of the delivery personnel. Then, based on the results, a pair of novel pants was developed. After that, 25 male students were recruited to compare the ergonomic performances between the novel work pants and traditional pants using both objective and subjective methods. It is discovered that the largest skin deformation rate was at the centerline in the upper (49.3%) and lower knee regions (52.3%) under riding activity. Novel work pants were then developed by creating folded structures in the regions based on the deformation rates, which could be stretched and shortened following human movement. Human tests revealed that the novel pants could significantly increase the range of motion of hip flexion and improve ease of move and comfort sensations in the knees and limbs as well as reducing pressure sensations in these regions. The novel work pants could effectively improve wearers’ mobility and comfort both in the limbs and was thus expected to reduce the limb fatigue and improve performance of the delivery personnel.

In visual inspection, the impact of different human factors on inspection performance has been evaluated in past. However, there is a need to study the effect of relevant factors and their interrelation in a single framework to monitor and improve inspection performance. This study aims to identify and evaluate such human factors for proposing a framework that indicates their interrelationship. After reviewing the literature, five constructs with their respective observed variables are selected to propose the framework. The survey instrument is developed using the suggested framework to collect data from industry professionals where human labor perform the inspection for products such as textiles. Finally, data are collected through an online survey and analyzed using confirmatory factor analysis to test the hypotheses. The results verify that the selected constructs are good measures of inspection skill, however, some variables are excluded from the model for being insignificant. Results show that the factors related to the constructs – personal, physical/mental, and organizational – are found more influencing than system and inspection-task factors. This study identifies and models the inspection-related significant factors into a framework that will help monitor and improve the performance of an individual or whole inspection station.

Ionic liquid, as a green solvent, has been widely used in high-tech fields. One of the uses is an excellent plasticizer for polymers, and a good plasticizing effect can be achieved for these polymers. 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) is a kind of ionic liquid, it possesses low melting point, strong polarity, high temperature stability, and other characteristics, which can be used as a highly effective plasticizer for polyacrylonitrile (PAN) to achieve plasticized spinning. In this review, for PAN fibers, plasticizing mechanism, raw material preparation, spinning process adjustment, structural chemical change, and fiber properties were summarized. At the same time, the related reports on plasticized spinning PAN composite fibers were reviewed as well. The field that has not yet been studied in depth was also discussed in this paper. It is hoped that this paper will provide an important basis for those people who will be engaged in further study on plasticized spinning PAN (PAN composite) fibers.

Pulp fiber airlaid nonwovens were bonded with three binder formulations in a spray and foam process. The binders were: a commercial acrylic dispersion binder, a commercial bio-containing acrylic binder; and a citric acid-carboxymethyl cellulose mixture (CACMC) (1:1 by-weight). The binder solutions were applied at same concentrations onto A4-size airlaid sheets (80 gsm) under a vacuum with 2-sided spraying and 1-sided foam coating. The sheet structure, dry and wet tensile properties, and total absorption capacity were compared. The foam application densified and bulk bonded the sheets, whereas the spray application induced surface bonding. These factors fundamentally influenced the measured sheet properties. The dry tensile strength was linearly correlated with the relatively low binder dosages. The CACMC binder exposed the differences in the binder application processes well, and lead to strong sheets with small elongation and highly application method-dependent absorption capacity compared to acrylic binders.
