It was based on the survey of paraplegics about the thermoregulation of their legs in cold environments,\u0000the warming of the legs during and after outdoor activities, the type of clothing for outdoor activities and the need for\u0000smart heating clothing for the lower extremities. The skin surface temperatures on the legs of fully mobile people and\u0000paraplegics were measured in a neutral state to find out to which temperature the microclimate inside the trousers can\u0000be warmed and the smart trousers can be used safely. The survey of paraplegics was conducted nationwide and\u0000included sixty-one adult male and female subjects. Skin surface temperatures were measured at eight measurement\u0000points on the right and left leg and performed on eighteen participants. After evaluating all the results of this study,\u0000recommendations for the design of smart heating trousers were proposed. The results of this part of the research can\u0000provide designers with important information about the specific requirements for smart heating trousers and enable them\u0000to design and develop products that meet real needs and are safe for paraplegic wheelchair users.

Surgical masks were designed in various ways according to colour, nose strip, earloop, grams per square meter\u0000and several layers. Some performance features are expected from these masks according to certain standards. In this\u0000study, it has been studied on multi-layered surgical masks. Thickness, air permeability, bacterial filtration efficiency and\u0000differential pressure properties of these masks consisting of polypropylene spun bond and melt-blown layers were\u0000investigated. The effects of an increase in grams per square meter, the number of layers and the melt-blown layer on\u0000the mentioned properties were determined. As a result; it has been observed that the optimal mask is one of the 4-ply\u0000masks. Also, it has been concluded that increasing the number of layers does not always provide an increase in\u0000performance; instead, an increase in grams per square meter can meet the expectation. Therefore, it can be said that\u0000it is necessary to determine the appropriate weight in grams and the appropriate number of layers with suitable raw\u0000materials to provide the expected features from the surgical masks.","PeriodicalId":13638,"journal":{"name":"Industria Textila","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140424360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yellow was chosen as\u0000one of four process colours which should theoretically suffer the most prominent changes from PEDOT:PSS\u0000overprinting. The study found that PEDOT:PSS ink significantly impacts the optical properties of the fabric and yellow\u0000ink, especially regarding the lightness and b-coordinate of the yellow ink. The acid treatment of samples, to increase\u0000PEDOT:PSS conductivity, also affected the optical characteristics through partial neutralization of the changes in the\u0000b-coordinate, especially when the sample was printed with a larger number of layers of the yellow ink and a smaller\u0000number of layers of PEDOT:PSS ink. Samples with two layers of yellow and one layer of PEDOT:PSS ink showed good\u0000conductivity results even without acid treatment, while the base colour appeared slightly darker. This change in the\u0000lightness can be compensated to some extent, proving that the aforementioned combination of PEDOT:PSS and base\u0000ink layers are the best when aspects, such as optical characteristics, conductivity, the complexity of production,\u0000production time, and limitations of the use of substrate materials are taken into account.

This study suggests a means for putting a nanofibre-based, intelligent,\u0000emotion-aware clothing system into practice. By recognizing and reacting to the wearer's psychological state, the system\u0000seeks to improve user convenience and well-being. In this study, a unique, self-sufficient weight-tuned Kohonen neural\u0000network (SW-KNN) method is used to categorize emotional states. To determine the wearer's emotional state, we first\u0000collect a dataset of signals from the body, including pulse, body temperature, and perspiration production. The dataset\u0000is then added to the preprocessing stage, where the raw data is normalized using the min-max method. The important\u0000features from the cleaned data are then extracted using the Fast Fourier Transform (FFT). The smart control unit\u0000processes the physiological signals that have been acquired. The proposed approach is utilized to categorize the\u0000wearer's emotional state, and the white shark optimization (WSO) approach is used to improve the classification\u0000accuracy. The control unit has a microchip and wireless connectivity abilities, enabling it to send the devices’ connected\u0000devices the classified emotional status. The clothing technology can continuously modify its features based on the\u0000identified emotional state to enhance the wearer's comfort.

The emergence of 3D knitting and its subsequent application\u0000in footwear manufacture has revolutionized the shoe manufacturing process. The use of knitwear allows for shoe parts\u0000such as the upper or the sole (insole, Strobel sole, midsole and/or outer sole) to be tailored with specific areas having\u0000different characteristics and providing different functions with low production effort. This study presents the design and\u0000manufacture of a knitted smart sneaker for cadence mensuration. The specified part of the sneaker is knitted with silverplated polyester yarn to serve as a strain sensor. During the weight-bearing and release phases of the foot, while\u0000walking, this strain sensor is stressed and relaxed by this oscillatory phenomenon thus allowing footstep data to be\u0000measured. Stride estimate tests were carried out and the results established that strides taken by a user can accurately\u0000be correlated to the readings of the system.

Moreover, skateboarding is\u0000becoming increasingly professional at an international level. Professional skateboarding trousers are regarded as critical\u0000equipment and their design research should not be overlooked. This research aims to use motion capture to measure\u0000the angular changes characteristics of critical lower limb joints in skaters during sports activities, measure the length of\u0000the knee joint during actions, and establish a formula that describes the change characteristics between the angle and\u0000the length. The formula would allow for a data reference when designing the elasticity at the knee joints of skateboarding\u0000trousers. Thus, the initial step in this research methodology was to use a Vicon motion capture system to test and\u0000analyse the kinematic characteristics of seven skaters in the squat, jump, ollie, pop shove it, heel flip, kickflip, and 180°\u0000ollie. Based on the kinematic characteristics, the dynamic movements were broken down into static postures at 0°, 45°,\u000090°, 112.5°, and 135°. The body surface drawing method was then employed to measure changes in the knee joint body\u0000surface dimensions of the subjects. Next, the experimental data were analysed to explore the relationship between\u0000angle and length changes. Finally, the design was developed based on the data. Analysis and processing of the\u0000experimental data yielded the following conclusions: (1) The most significant knee joint change characteristics during\u0000skateboarding was the angle change observed during an ollie. (2) Knee joint skin stretch deformation is most evident in\u0000the anterior mid-leg line y2. (3) The relationship between kinematics and the structural design of skateboarding trousers\u0000was derived from the experimental data. Specifically, the equation for the relationship between angle change and length\u0000change is given by y2 = 0.0442x + 23.906. (4) The results show that the extreme range of skin stretching in the anterior\u0000midline is between –0.7 and 6.3 cm. Therefore, the loose design of the knee part of professional skateboarding trousers\u0000should not exceed 6.3 cm. This research approach can offer an effective design solution for professional skateboard\u0000trousers and can also be applied to other types of trousers.","PeriodicalId":13638,"journal":{"name":"Industria Textila","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140427030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
