The effect of different microneedles (MNs) densities on drug release was studied by using silk fibroin with good biocompatibility as the substrate of microneedles. The mixture of D-sorbitol and silk fibroin at the ratio of 2:10 was poured into a polydimethylsiloxane mold. After vacuum extraction, constant temperature and humidity drying, the silk fibroin microneedles were obtained. Three kinds of microneedles arrays of different densities were prepared with the area of 1 cm2: 5×5, 10×10 and 20×20. The length of silk fibroin microneedles was controlled at about 600 µm, and D-sorbitol/silk fibroin blend film was used as the control group. Melatonin was selected as the model drug and three kinds of MNs and blend film were used to study the drug release in vitro experiment. The aggregation structure of D-sorbitol/silk fibroin MNs was measured by X-ray diffraction (XRD) and infrared spectroscopy. The anti-compression properties of three kinds of MNs were measured by texture analyzer (TMS-PRO). The results showed that: (1) D-sorbitol could change the silk fibroin from random coil structure to the crystal structure of Silk I, and the dissolution rate of Silk fibroin MNs was low and the swelling property of silk fibroin was certain. (2) All three types of MNs have good compression resistance and puncture performance. It can effectively open the channels for drug delivery and relieve pain. (3) All three types of MNs have good drug release properties. As the density of the MNs increases, the drug release rate and cumulative drug release rate increase. As the density of the MNs increases, the compression performance of the MNs is improved. All three types of silk fibroin MNs have good penetration effects and can achieve slow-release effects. Compared with silk fibroin film without MNs, silk fibroin MNs can significantly increase the drug release rate by opening skin micropores.

Modern technologies and developments have a major impact and contributions to a massive increase in the various types of hazards to which human beings are exposed. The protection from flame, fire, heat radiation sources, etc., is a principal requisite for both civil and defense applications. Textile fabrics constructed from natural fibers have been used traditionally for ordinary protection. Hence, the focal objective of the present research work was to scrutinize the improvement in thermal resistance/insulation performance of the flame retardant cotton fabrics treated with milk casein, a biomacromolecule-based flame retardant. Milk casein (a phosphorous-containing protein) was applied, as a green flame retardant finishing material, on the cotton fabrics through aqueous solutions by using an industrially applicable method. In order to evaluate the thermal protective performance, single-layer casein treated cotton fabric samples were exposed to a radiant heat source at a specific radiant heat flux density (Qo) as per ISO 6942-B standard test method. The transmitted heat flux density (Qc) and heat transmission factor (TFQo) were discerned to shift towards the lower values for the casein treated cotton fabric samples as compared to untreated cotton fabric indicating the enhanced thermal protection phenomenon.

Besides automatic looms in factories, looms for hand-weaving have also been used at home for producing handicrafts. Since the number of healds is small in rigid looms, it is necessary to pick up warp yarns by hand for each weft yarn. This operation is rather cumbersome when the sequences of warp yarns to be picked up are irregular. This paper proposes a method for generating approximate weave diagrams via warp pick up assignment. We represent the difference of weave diagrams in terms of tiling and image features to reflect their topological char-acteristics. Based on this representation, we propose a sequential re-assignment algorithm to generate approximate weave diagrams. The properties and time complexity of the proposed algorithm are reported. The proposed approach is validated in terms of the performance of the algorithm and woven fabric.

In order to solve the contradiction between economic development and environmental problems, the trend of recycling strategies increases the value of textiles and other waste in the supply chain. Fashion companies have been trying to develop sustainable clothing made from post-consumer plastic bottles, but few studies have explored the practice and innovation of plastic waste in clothing design from the fashion perspective. Considering the complexity of plastic waste recycling, this article explores the possibility of upgrading and recycling plastic waste in clothing fabrics through the analysis and performance analysis of plastic waste materials. On this basis, the design hypothesis of waste plastics on the sustainability of clothing is proposed to establish the basic framework of the design. According to the design framework, two kinds of waste plastic materials are explored in the pre-experiment. Through the comparison and evaluation of the pre-experiment effect, a feasible scheme is finally selected for the overall design of a clothing series in visual display.

The global economy has experienced a downturn due to the COVID-19 epidemic, and the entire apparel industry has been hit hard. However, in the post-epidemic era, the digital trend of the world has become more pronounced. The virtual consumer market and virtual fashion took this opportunity to overgrow. More and more people are willing to spend money on virtual products. In a way, virtual fashion is the acceleration and continuation of future fashion trends. The most crucial difference between virtual and physical fashion is that the latter does not undergo physical production. Instead, virtual clothing can be purchased and “worn” immediately. More and more fashion brands have paused traditional fashion shows in favor of visuals such as video game collaborations, mobile apps, virtual icons, virtual showrooms, and virtual clothing brands. This paper compares and analyzes ten international brands associated with virtual fashion through data collection and case studies. It shows that with the help of modern cutting-edge technology, the traditional apparel industry has ushered in a new transformation point. New virtual fashion will gradually enter our daily life from the experimental field, driving the transformation of the apparel industry.
