Effectiveness of Using Custom Made Soft Corset Model Towards Abdominal Circumference in Postpartum

Background: During the postpartum period, mothers often seek to maintain abdominal slimness by utilizing compression garments like stagen or bengkung. However, advancements in textile technology have led to a decline in the popularity of stagen, with corsets emerging as a preferred alternative due to their perceived practicality. Corsets, known for their flexible yet durable woven texture, serve as effective abdominal binders, aiding in both aesthetic preservation and posture Purpose: This study aimed to evaluate the effectiveness of custom-made soft corsets in reducing abdominal circumference among postpartum mothers. The findings are anticipated to offer insights into the comfort and efficacy of using these corset models to promote abdominal muscle tightening in postpartum individuals. Methods: The design is quasi-experimental. Data analysis includes univariate analysis in the form of respondent characteristic data and multivariate analysis with General Linear Model Repeated Measures (GLM RM). Results: The difference in average abdominal circumference in the intervention group decreased, namely in measurement I of 89.4 cm (SD = 8.56), measurement II of 77.67 (SD = 7.51) cm and measurement III of 69.67 cm (SD = 8.41), while low back pain of measurement I of 2.73 (SD = 0.46), measurement II of 1.80 (SD = 0.56) and measurement III of 0.40 (0.51). Conclusion: Custom made soft corset treatment for postpartum mothers proved to be more effective in reducing the size of abdominal circumference, namely in the results of the analysis of the interaction between the second and third measurements, seen from a steeper slope, and in low back pain measurements seen from a steeper slope between the first and second measurements.

Manufacturing Variations in ISO Blue Wool Fading Standards under Microfading Exposure Conditions

ABSTRACT As is the case for other accelerated light-ageing methods, microfade test results are usually rated against the responses of the International Standards Organisation’s Blue Wool Fading Standards, the production of which is regulated by the International Standards Organisation. The suitability and convenience of the ISO Blue Wools for this purpose have been questioned on various grounds, including wavelength sensitivity, manufacturing or batch response variations, and the effect of their woven texture on systematic errors. In the present article, the effect of manufacturing variations was assessed by carrying out microfade testing on samples of ISO Blue Wools from various suppliers and manufacturers spanning more than 20 years. Our results confirm that the first three ISO Blue Wools, which are of most relevance to locating colourants at risk of significant light-fading on display in museums, had measurable batch-to-batch and/or manufacturer variations in fading rates, most significantly in the case of Blue Wool 2. Different batches were often also distinguishable by their colour and the texture of the wool fabric. It is argued that while texture-related systematic errors and manufacturing variations are inconvenient, they are not significant in light of the other potential sources of disparity between the results of accelerated exposure tests of any kind and fading at ambient light levels, and it is concluded that the advantages of the use of ISO Blue Wools as internal standards for microfade testing outweigh their disadvantages.

Research on a Segmentation Algorithm for the Tujia Brocade Images Based on Unsupervised Gaussian Mixture Clustering.

Tujia brocades are important carriers of Chinese Tujia national culture and art. It records the most detailed and real cultural history of Tujia nationality and is one of the National Intangible Cultural Heritage. Classic graphic elements are separated from Tujia brocade patterns to establish the Tujia brocade graphic element database, which is used for the protection and inheritance of traditional national culture. Tujia brocade dataset collected a total of more than 200 clear Tujia brocade patterns and was divided into seven categories, according to traditional meanings. The weave texture of a Tujia brocade is coarse, and the textural features of the background are obvious, so classical segmentation algorithms cannot achieve good segmentation effects. At the same time, deep learning technology cannot be used because there is no standard Tujia brocade dataset. Based on the above problems, this study proposes a method based on an unsupervised clustering algorithm for the segmentation of Tujia brocades. First, the cluster number K is calculated by fusing local binary patterns (LBP) and gray-level co-occurrence matrix (GLCM) characteristic values. Second, clustering and segmentation are conducted on each input Tujia brocade image by adopting a Gaussian mixture model (GMM) to obtain a preliminary segmentation image, wherein the image yielded after preliminary segmentation is rough. Then, a method based on voting optimization and dense conditional random field (DenseCRF) (CRF denotes conditional random filtering) is adopted to optimize the image after preliminary segmentation and obtain the image segmentation results. Finally, the desired graphic element contour is extracted through interactive cutting. The contributions of this study include: (1) a calculation method for the cluster number K wherein the experimental results show that the effect of the clustering number K chosen in this paper is ideal; (2) an optimization method for the noise points of Tujia brocade patterns based on voting, which can effectively eliminate isolated noise points from brocade patterns.

Laser Induced Dyeing (LID) with Reactive Blue 21 on Hemp Fibers

Effects of 532 nm and 320 mJ laser beam on aqueous solution of Reactive Blue 21 (RB21), a copper based on reactive dye, have been studied in both presence and absence of garnet gemstone with the aim to receive a proper coating of the hemp fibers contained in the yarns of a woven texture while reducing the dyeing time compared to the classic exhaustion dyeing method. Results show that both laser beam and garnet influenced the dyeing process with RB21, enhancing the absorption and reaction of RB21 with the composite structured hemp fibers, effect observed in the color intensities for all samples measured with the grayscale. The best results are noticed for laser effects in presence of garnet gemstone when highest coating is achieved among all samples, and the process is 11 times shorter than the classical exhausting method. Compared FTIR and UV-VIS spectra of initial dyestuff and residual dyestuff isolated from the wastewaters offered information about dyestuff exhaustion process under garnet and/or laser influence. Laser Induced Fluorescence completed the study with the information about RB21 behavior under UV laser beam of 362 nm.

Effects of three fabric weave textures on the electrochemical and electrical properties of reduced graphene/textile flexible electrodes.

Textile textures formed through woven, knitted or nonwoven weaving technology have critical effects on the electrical and electrochemical properties of flexible electrodes. Therefore, the effects of textile structures, including porosity and pore configuration, on the loading amount of reduction graphene (RGO), the electrical and electrochemical properties were systematically studied. The results show that knitted fabric had the highest mass loading of RGO sheets and lowest sheet resistance among these three fabrics. However, the specific capacitance of woven fabric was optimum 40.5 F g−1 at a scan rate of 5 mV s−1 within the voltage window of 0–0.8 V, which was ascribed to its suitable porosity and pore size firmly anchoring the RGO sheets. Also, the RGO/woven cotton electrodes exhibited good cycling stability and excellent electrochemical stability without an obvious loss in the capacitive performance. The above results provide a theoretical basis for the selection of textile substrates for high-performance flexible electrodes.

Long bone histology of Chersina angulata : Interelement variation and life history data.

The current study deduced the growth pattern and lifestyle habits of Chersina angulata based on bone histology and cross-sectional geometry of limb bones. Femora, humeri, and tibiae of seven different-sized individuals representing different ontogenetic stages were assessed to determine the interelement and intraskeletal histological variation within and among the tortoises. The bone histology of adult propodials consists of a highly vascularized, uninterrupted fibrolamellar bone tissue with a woven texture in the perimedullary and midcortical regions suggesting overall fast early growth. However, later in ontogeny, growth was slow and even ceased periodically as suggested by slowly formed parallel-fibered bone tissue and several growth marks in the pericortical region. In juvenile individuals, fibrolamellar bone tissue is restricted to the perimedullary regions of propodials as remnants of bone formed during the earliest stages of ontogeny. The epipodials are characterized by having parallel-fibered bone tissue present in their cortices; however, periodic arrests in growth are recorded at various times. Remnants of fibrolamellar bone tissue formed during early ontogeny occur in the epipodials of only a few individuals. Interelement variation is evident, in terms of variation in the orientation of vascular canals between individuals and within the same diaphyseal cross-sections. Different elements show varying cross-sectional geometry, which appear to be correlated with the fossorial behavior of the species. Our results show that of all the long bones, the tibia is least remodeled during ontogeny and it is therefore the best element for skeletochronology.

Picture-frame testing of woven prepreg fabric: An investigation of sample geometry and shear angle acquisition

This paper examines different concepts in relation to the picture-frame test for shear characterization of a woven prepreg fabric. The influence of the sample arms is investigated by means of cut slits as well as removed transverse tows. Shear angles are obtained using Digital Image Correlation (DIC) and also from images taken during the test which are processed for fiber angles directly from the weave texture. The image processing relies on the Hough transform in MATLAB. The concept of constant shear strain rate is discussed and implemented in the test software by a multi-linear crosshead velocity profile. Finally, bias-extension data are obtained and used for comparison. It is found that the sample arm modifications have a pronounced effect on the measured shear load whereas the uniformness of the shear strain field in the samples is not improved considerably.

Factors affecting fabric slipperiness

Fabric slipperiness is an important property whose impacts include clothing comfort, sports records and the medical or safety performance of anti-slip or slippery textile products. The characteristics of fabric slipperiness have been studied under limited conditions and with samples with regard to the fabric component. In this study, the MIU (average value of the friction coefficient), which is correlated with the slipperiness or non-slipperiness of fabrics, and MMD (fluctuations of the average frictional coefficient), which is correlated with the smoothness or roughness, were measured for more than 50 versatile fabrics by using the friction tester, KES-SE. As a result, it was found that the friction coefficient was mainly determined by the linearity of weave texture, the fuzziness of the fabric and the real contact area between fabrics and rubbed materials, which are proposed as new factors of fabric slipperiness; this approach contrasts with the past approach, which mainly relied on the fabric structure. The relation between MIU and each factor was not analyzed separately but instead analyzed from a new comprehensive and statistical point of view. This approach made it possible to obtain the practical contribution ratio of these factors for application in the design of new slippery or anti-slip textiles that are useful for our lives. On the other hand, the smoothness had nothing to do with those factors, rather, it was related to the three-foundation weave texture of the fabrics.

Enhanced thermal and mechanical properties of liquid crystalline-grafted graphene oxide-filled epoxy composites

Epoxy composites with biphenyl liquid crystalline polyester (BLCP)-grafted graphene oxides (GO) as inclusions were prepared successfully. The thermal and texture analyses of BLCP were characterized by DSC and POM. The results show that the texture structure of BLCP turned into fan texture from woven texture with increasing temperature and present double texture structure. More importantly, the thermal and mechanical properties of epoxy composites could be improved by incorporating BLCP-grafted GO (BLCP-GO). The epoxy composite with only 0.5 wt% BLCP-GO produced an increase in the initial decomposition temperature (T d) by 28 °C and glass transition temperature (T g) by 17.2 °C when compared with the neat epoxy. Moreover, for the mechanical properties tests, the composites with 1.0 wt% BLCP-GO exhibit an increase in impact strength, tensile strength, flexural strength and flexural modulus by 103, 52, 66, and 56 %, respectively, compared with the neat epoxy resin. These excellent performances of the graphene–epoxy composites have a great potential for applications in aerospace and other electrical devices.

Diamond-shaped shaded weave series created by transforming small twills to enrich the surface texture of woven Jacquards

Digital Jacquard textiles have been introduced through various approaches to the capability enhancement of color expression and novel design proposition in modern weaving. Because of its a wide scope of weave colors with a small number of fillings, the basic weave structure of satin is widely adopted in the creation of shaded weave series, as they are highly reliable in presenting the natural color shading with maximized luster. However, its surface texture is limited with consistent traverse lines attributed to regular stitching points in their structure combination. Therefore, a new silhouette of shaded weave series is proposed and explored with twills to enlarge and vary the woven texture effects. The shading effect with single twills will be presented in a linear and contrasting way; when small twill lines are cut and replaced, the converted format will enable the creation of a varied surface touch. By finding the base marks where the total interlacement of a repeat is proportionally divided, small twill lines are transformed by adding interweaving points to build into a series. Furthermore, the basic principles received from satin-based shaded series are applied to the achievement of gradient shading effects. In terms of weave pattern design, each color layer is individually designed with levels of grayscales and defines each color region and color density to achieve a high-quality color presentation, as well as a unique texture.

Image analysis of weaverbird nests reveals signature weave textures.

In nature, many animals build structures that can be readily measured at the scale of their gross morphology (e.g. length, volume and weight). Capturing individuality as can be done with the structures designed and built by human architects or artists, however, is more challenging. Here, we tested whether computer-aided image texture classification approaches can be used to describe textural variation in the nests of weaverbirds (Ploceus species) in order to attribute nests to the individual weaverbird that built them. We found that a computer-aided texture analysis approach does allow the assignment of a signature to weaverbirds' nests. We suggest that this approach will be a useful tool with which to examine individual variation across a range of animal constructions, not just for nests.

Synchrotron imaging reveals bone healing and remodelling strategies in extinct and extant vertebrates.

Current understanding of bone healing and remodelling strategies in vertebrates has traditionally relied on morphological observations through the histological analysis of thin sections. However, chemical analysis may also be used in such interpretations, as different elements are known to be absorbed and used by bone for different physiological purposes such as growth and healing. These chemical signatures are beyond the detection limit of most laboratory-based analytical techniques (e.g. scanning electron microscopy). However, synchrotron rapid scanning–X-ray fluorescence (SRS–XRF) is an elemental mapping technique that uniquely combines high sensitivity (ppm), excellent sample resolution (20–100 µm) and the ability to scan large specimens (decimetre scale) approximately 3000 times faster than other mapping techniques. Here, we use SRS–XRF combined with microfocus elemental mapping (2–20 µm) to determine the distribution and concentration of trace elements within pathological and normal bone of both extant and extinct archosaurs (Cathartes aura and Allosaurus fragilis). Results reveal discrete chemical inventories within different bone tissue types and preservation modes. Chemical inventories also revealed detail of histological features not observable in thin section, including fine structures within the interface between pathological and normal bone as well as woven texture within pathological tissue.

Influence of diamond wheel grinding process on surface micro-topography and properties of SiO2/SiO2 composite

According to anisotropic and inhomogeneous structure of fiber-reinforced ceramic matrix composites (FRCMC), it is difficult to control the surface quality with the traditional method used in metal material. The present paper studies the influence of diamond wheel grinding process on surface micro-topography and properties of SiO2/SiO2 composite. The research is based on some new discovery that the material enhanced fiber orientations play a key role in micro-topography of FRCMC grinding surface. Through a series of experiments, we investigate the relationship between grinding process and the quality of composites surface. We also analyze characteristics of the material surface topography height, wave distribution and surface support properties in details. This paper employs the orthogonal design to optimize grinding process parameters and also successfully models a critical condition to modify the surface characteristics. The results show that speed of grinding wheel has the greatest influence on height and surface support properties, the next is grain mesh size and depth of cut. The grain mesh size is the key factor for surface micro-topography modification. Compared to the surface with woven texture, the modified surface has better symmetrical characteristic. The research obtained will be an important technical support on improving the processing quality of FRCMC.

Experiments prove the method practical and useful for fabric weave computer automatic analysis.

Cognitive Weave Pattern Prioritization in Fabric Design

Weave patterns are amongst the most popular design patterns in society’s daily lives with numerous applications. In the fabric design process, designer selects weave patterns based on the cognitive interpretation of the material structure in the fabric texture. In the selection activity of weave patterns, texture indexing and prioritization are curial tasks. These are associated with a cognitive process of interpretation and understanding of the texture elements in the woven structure of fabrics. In this regard, the authors use an interdisciplinary approach to help designer select weave texture patterns through structure and texture features and implement new algorithms that take into account essential features or rules in fabric pattern design. The features and algorithms are designed based on the object-attribute-relation (OAR) model and a cognitive informatics model. Three essential cognitive features of weave patterns are proposed, (1) the complexity of patterns in the fabric production process, (2) the structural appearance feature, and (3) cognitive tracking features for weave patterns. The authors’ experiments on a wide variety of weave patterns show that the proposed approach is capable of effectively prioritizing the cognitive features of weave patterns in fabric texture design process.

Diaphragm for Speaker, Speaker Using the Diaphragm for Speaker, and Process for Producing The Diaphragm for Speaker

A speaker diaphragm which includes a woven cloth which contains a thermosetting resin of thermo-cured state, and a paper board bonded and integrated with the woven cloth at the back surface. The woven cloth has its weave texture exposed on the front surface. The diaphragm has a high strength because it is made with a woven cloth; furthermore, its hardness is high because the thermosetting resin impregnated in woven cloth is in thermo-cured state. Thus the diaphragm helps implementing a speaker which demonstrates superior vibration characteristics in the high frequency sound region.
