Abstract

Finding the most efficient marker planning method is crucial to reduce cut-and-sew waste. Small adjustments to the design and pattern can help reduce the amount of fabric waste, since marking loss happens during the cutting process because of spaces and unusable sections between pattern pieces and the curved pattern edges.
Existing research mainly concentrates on optimising the consumption of textile material without taking into account the design, aesthetics and functionality of the final product. On the other hand, they are mainly focused on optimizing the sleeves’ construction and in search of new design solutions, with gaps in quantitative and comparative analysis to reduce waste while producing women's jackets.
This article aims to propose and explore constructive changes in women's jacket designs with 5 different types of sleeves, to assess the possibility of reducing cut-and-sew waste levels in the cutting process. There have been created 4 different marker plans for each type of sleeve to achieve the high-efficiency markers. It was found that the semi-raglan sleeve showed the marker efficiency with the best results (76.04%), followed by the raglan sleeve with 72.03% and 72.34% for the drop shoulder sleeve. Interestingly, for the raglan and semi-raglan sleeve variants, the marker efficiency is not affected by the specific geometric characteristics.
The Principal Component Analysis (PCA) method was used to determine which pattern arrangement variant was most appropriate for the different sleeve types.

Abstract

To explore whether a carbon trading pilot (CTP) can promote the low-carbon development of China's textile industry (CTI), this paper used a difference-in-difference model to study the impact of CTP on the carbon emissions in CTI and further analysed its regional heterogeneity. The research results showed that the impact coefficient of CTP on the carbon emissions in CTI was significantly negative, indicating that CTP could reduce the carbon emissions in CTI. Robustness tests such as the Placebo test, replacing the explained variable and the estimation method and excluding the interference of other policies verified the robustness of the research results. The dynamic regression results revealed the carbon reduction effect of CTP became stronger as the time of its implementation increased. At the regional level, CTP could also significantly lower the carbon emissions in the textile industry both in the eastern and western regions, and the reduction effect in the western region was greater than that in the eastern.

Abstract

This paper presents a multidimensional analysis of textiles coated with conductive polymers for actuators. The purpose of using multidimensional scaling analysis is to compare similarities and dissimilarities between conductive textiles obtained through conductive polymeric film deposition to observe the optimal value for electrical resistance and to select an adequate method to achieve conductive fabric using different polymers (polyethylene glycol, polyvinyl alcohol or polyvinylidene fluoride) and metal microparticles (copper or nickel). The multidimensional analysis is based on mapping a series of material properties from a proximity matrix (similarities or dissimilarities) between these properties. Multidimensional scaling allows rebuilding the exact map of the values (within approximately a symmetry or rotation). To fit dissimilarity or similarity matrices for multiple variables into one common space estimating the weight parameters for each variable, the INDSCAL model (individual differences multidimensional scaling) was used.

Abstract

The research aims to evaluate the solidity of the washing colour of a garment printed with flexible filaments on 3D printers. Three groups of factors have been selected: Anet A8 and M3D Crane Quad printer, temperature (49° and 71°C) and flexible filaments TPE (thermoplastic elastomer) and TPU (polyurethane thermoplastic), framed in the factorial design, type applied of 10 units per combination of factors in a total of 80 sampling units, using Girowah equipment according to the technical standard AATCC TM61-2020. The results show that the printer factors Anet A8 and M3D Crane Quad with the CIELab and CMC (2:1) discolouration system exceed 50% in both the tolerances of the value 1. About the temperature factor (49° and 71°C), which exhibits a discolouration of 1.06 in CIE94 and 1.36 in CMC, it is determined that the combination with better resistance to discolouration of solidity at washing (CIE94 - 49°C) compared to CMC (2:1) better establishes the visual and technical concordance of the solidity of colour. As regards flexible filament types: TPE and TPU, the results show us that the colour tolerance assessments (CIELab CIE94) and (CMC (2,1)) prove that the TPE filament has greater resistance to the discoloration of the 3D-printed garment at different temperatures. In conclusion, the solidity of colour washing in a printed garment with flexible filaments in a 3D printer causes discolouration by the minimum, be it the factors of printer type, filament, and temperature. There is a need for analysis with other values and it remains open to other research.

Abstract

This study aims to examine the mechanical and burning properties of composites made from twill (0°/0° and 0°/90° orientations) and plain fabrics using hybrid yarns produced by combining glass and polypropylene yarns with interwoven and intermingled methods. The properties of interwoven and intermingled hybrid fabric composites were compared with thermoset composites. Each composite (56% glass fibre content) plate is produced by combining eight fabrics with the same parameters using the press moulding technique. The effects of yarn and fabric weaving types on the results were examined in detail. When the results are examined, the breakage of glass fibres in intermingled hybrid yarns negatively affects the strength results. Therefore, composites made with intermingled hybrid yarn types and plain weave types of fabric had the lowest tensile strength value (132 MPa). The composite of twill woven fabrics produced with interwoven yarns arranged in 0°/0° orientation had the highest tensile strength of 315 MPa, and these results were very close to those of thermoset composites. Although the 0°/90° oriented twill composite showed a 2.3 times lower tensile strength value than the 0°/0° oriented twill composite, it had a 7.7 times higher value when bending strength values were taken into account. The main reason for this is that glass fibres contribute to the warp and weft directions. It has been observed that the composite consisting of plain fabrics woven with commingled hybrid yarns had the highest impact resistance. Additionally, when the combustion results were examined, it was concluded that the type of yarn and fabric weaving affected the burning rate. The slower combustion of hybrid commingled yarn composites resulted from fibreglass breakage during yarn production. These findings provide valuable insights into optimizing composite materials for specific applications, considering factors such as weaving pattern, fibre orientation, and mechanical performance.

Abstract

The existing worldwide information related to the aerial modules used for transporting mulching substances is particularly pernicious. Thus, at this moment, on an international level, cargo transport solutions for mulching lands affected by soil drought are limited to identifying the maximum value of the load (1250–4500 kgf), the type of raw material from which it is made (polyamide), the shape (quadratic, octagonal, rectangular) and its dimensions (2.13 m × 3 m for a maximum transport capacity of 1250 kgf – 5.5 m × 5.5 m for a maximum transport capacity of 4500 kgf). Also, among the solutions for protecting lands affected by wildfires, the sowing technique with the help of drones was identified. Thus, the seeded compost balls are allowed to fall by gravity from the drones, being released randomly in the demineralised areas, difficult to reach by land transport. The paper presents the latest research of INCDTP specialists – carried out in the national premiere – regarding the iterative-incremental development of a multi-role collapsible aerial module that has as its theatre of operations the desertified areas (due to the pedological drought) of Romania. The central point of the research is focused on: i) the experimentation in the accredited laboratories of INCDTP, of flexible panels joined by mechanical-textile technology; ii) statistical analysis of values; iii) predicting the minimum values of the physical-mechanical characteristics of the composite material.

Abstract

The dynamic of cooling heat flow during evaporation of the simple jersey polyester fabrics was investigated in this study. The holding period as a new parameter was introduced to study the dynamic of cooling heat flow during evaporation from the skin through the jersey knitted fabric. The holding period intervals were chosen as follows: 0, 30, 60, 90, 120, 180, 240 and 300 seconds.
The Permetest skin model was used to study and visualize the dynamic of the cooling heat flow at different holding periods. Results demonstrated that adding elastane makes fabrics less cool. Three different stages were noticed concerning the cooling heat flow dynamic: the first with a maximum heat flow (Qmax) indicating the first contact properties of a textile material with the skin. The second is a transition phase where the cooling heat flow decreases to the minimum heat flow (Qmin), and then it reaches the equilibrium (Qeq) mentioning the beginning of the third stage with a constant heat flow. It was found that the holding period does not affect the measured water vapour resistance, in the case of polyester jersey fabrics.

Abstract

To explore the differences in sensory imagery produced by different geometric patterns and dress silhouettes, this study selected and extracted 4 different types of geometric patterns and 4 typical dress silhouettes as research carriers, determined the research samples through cross-combination, and used 8 pairs of sensory word pairs as research semantic space. Consumer sensory evaluations of the dress samples were collected through a survey questionnaire. The results were analysed using SPSS26.0 software, which showed that three sensory factors affect the appearance of the dress style. According to their main characteristics, they can be named as personality factor, temperament factor, and style factor. In terms of the silhouette of the dress, the neat and regular geometric pattern is most affected by the silhouette of the dress, while the other three types of geometric patterns are relatively weak. In terms of geometric pattern rules, different geometric patterns have different effects on the overall appearance of the dress after being combined with the silhouette of the dress, and some dresses play a certain role in all three factors.

Abstract

Contemporary literature argues that the exchange rate serves as an important instrument of industrial policy to boost economic growth. However, it is difficult to design effective exchange rate policies owing to the uncertainty shrouding the outcomes of the exchange rate movement for industrial growth. Therefore, this study uses a dynamic simulated autoregressive distributive lags approach to study the impact of positive and negative changes in the real effective exchange rate on industrial production of Malaysia for the period 1970–2022. We employ an extended production function to study this relationship by incorporating capital, labour and globalisation as additional explanatory variables. The findings suggest that positive (negative) changes in real effective exchange rate are followed by positive (negative) changes in economic growth in the long run. Furthermore, positive changes in capital affect economic growth positively and significantly in both the short and long run. Finally, positive (negative) movement in labour and globalization positively (negatively) and significantly affect industrial production in the long run respectively. Policymakers should depreciate currency to expand industrial production in Malaysia. Moreover, to boost industrial production, short-term loans should be introduced for capital accumulation.

Abstract

The Qing Dynasty Lu-silk Apron in the Shanxi Folk Museum is a representative example of the traditional Chinese Apron, with profound cultural and aesthetic connotations regarding pattern type, colour application, and process techniques. Nevertheless, a minimal survey has been done on the Qing Dynasty Lu-silk Apron. The study aimed to discuss the exquisite textile techniques and artistic features of the Qing Dynasty Lu-silk Apron and analyse the social system, humanistic sentiment, cultural symbolism, and intelligent thinking at multiple levels through style types, size analysis, colour interpretation, pattern expression techniques, and skill production. In this article, we also used the popular simulation technology to restore the Qing Dynasty Lu-silk Apron and provide a new way and path to study other ancient costumes.

Article: Textile fabric's in-plane water permeability determination during wicking

Abstract

Based on a mathematical formulation of the water flow for different wicking configurations (ascendant-horizontal and descendant), a combined ascendant, horizontal and descendant wicking experimental test was designed to provide detailed measurements of the pertinent wicking performance properties: capillary pressure and in-plane direction permeability. This method was proposed due to capillary flows found in standard vertical wicking tests as well as erroneous assumptions made in other wicking tests. The effective capillary radius was assumed to remain constant as the height of the liquid increases. This assumption would suggest that saturation, capillary pressure, and permeability are also constants. However, experiments show that these properties are only constants in the case of the descendant wicking when liquid front height is varied. The capillary pressure and permeability calculations were made using Darcy’s law and the Lucas-Washburn equation as a function of the saturation level. In the combined wicking test, conducting a horizontal wicking test allows us to calculate the effective capillary radius of a fabric as the saturation rate was found to be constant, which in turn can be used to solve for capillary pressure. That capillary pressure can then be used in a descendant wicking test, where the liquid front flow and the saturation rate remain constant, and Darcy’s law to solve for permeability. A series of experiments was conducted on cotton jersey knitting. The results showed that the ability to wick the water depends on pore size and porosity scales: macro and micropores. The in-plane water permeability was found to be directly related to the saturation rate.

Abstract

The out-of-plane behaviour of 8 different composites exposed to very high deformation rates and non-standard conditions was investigated in our previous studies. The mechanical properties of these composites have been evaluated through tests conducted at deformation rates comparable to those experienced during explosions. Based on the relevant test results, this study conducted a numerical analysis of 3 best-performing Aramid UD GS3000, Artec Aramid/Woven Aramid CT736, and H62 UD-UHMWPE-reinforced composites. In this regard, LS-DYNA's MAT54 model was compared with other failure mechanics-based models and preferred because it requires less experimental data and can simulate damage progression in dynamic failures. Since the samples used in the study were non-standard, quasi-static tensile and shear tests were performed based on the loads to which the composites would be exposed to create an accurate numerical analysis. Both tensile and shear strength values of the Artec Aramid/Woven Aramid CT736 composite are higher than those of the Aramid UD GS3000 and H62 UD-UHMWPE composites. When the numerical analysis results were compared with the tensile test data, compliance rates of 99.84% for Aramid UD GS3000 reinforced composite, 99.34% for Artec Aramid/Woven Aramid CT736 reinforced composite, and 96.42% for H62 UD-UHMWPE reinforced composite were determined. The analysis showed that the shear stress-strain curves provided 100% agreement at the maximum stress value.

Abstract

The present paper aims to highlight the correlations between the comfort indicators of waterproof cotton-based fabrics, and the specific parameters of unconventional assembly technology. The materials considered include layers of Gore-Tex film, serving as substitutes for waterproof materials, intended to manufacture outerwear products such as protective equipment (jackets and overalls), which are breathable waterproof membranes. The comfort indicator values were obtained through standardised methods, and data processing and representation in two-dimensional (2D) and three-dimensional (3D) systems using correlation/graphing methods were carried out in Excel software, and using Jandel Table Curve 3D v2. Although experimental research can be extended to include specific functions related to durability indicators, this study focused theoretically and experimentally on how the variation in temperature of the low-pressure hot air jet can lead to changes in the vaporization coefficient, air permeability index, and thermal conductivity coefficient. The relationship between the comfort indicator values (thermal conductivity coefficient, air permeability index, and vapour permeability coefficient) of the considered materials and the treatment parameters of the installation (pressure, temperature, velocity) is expressed through statistically adequate mathematical models, highlighted by a correlation coefficient R = 0.983, with significance certified by the Fischer test. The study of comfort indicators was conducted under optimized treatment parameters, ensuring durability and presentation value functions in the treatment zone remain unchanged compared to those of the base materials.

This paper presents mathematical modelling based on predictive and correlation analysis of independent and dependent variables of conductive materials to develop sensors or actuators. The resulting analysis and optimisation develop improved systems based on sensors or actuators, including selecting the appropriate conductive materials for development. Toward this purpose, 46 materials with electroconductive properties were selected and analysed. The independent variables considered were mass, air permeability and thickness, and the dependent variable was defined as the electrical surface resistance of the conductive fabric used.

Abstract

This research examines how impact energy spreads across para-aramid fabrics, comparing woven and unidirectional types, using 2-D Thin Plate Spline analysis. The experiment involved dropping a weighted hemisphere onto fabric samples and measuring their deformation across different layer counts. To assess how yarn orientation affects energy dispersion, panels with 0º/90º and 0º/90º/±45º configurations were tested. By analysing the fabric's shape changes under impact, the study revealed patterns of energy propagation. Calculations of bending energy and expansion factors provided insights into this behaviour. The findings indicate that unidirectional fabrics outperform woven structures in distributing impact energy across their surface. Moreover, incorporating ±45º fibre reinforcements in both fabric types enhances energy dispersion and mitigates impact effects.
