It is found that there are very significant correlations between the corresponding parameters for extensibility and shear rigidity obtained from the test results of the two systems. The correlation between the values of bending rigidity obtained from the two systems is only moderate. Furthermore, for the fabrics tested in this study, the values of bending rigidity, shear rigidity, and extensibility measured using the KES - F instruments are higher than those of the corresponding parameters measured using the FAST instruments. The linear regression equation is given for each pair of corresponding parameter.展开更多

It has a high incidence rate and can induce sepsis and even death. The fabrics that touch patients’ skin directly have a profound impact on their skin surfaces. This review summarizes the research in the last five years on the relationship between pressure injuries and fabrics. Following the preferred reporting items for systematic reviews and meta-analyses(PRISMA) statement, a systematic literature search is conducted in nine databases, including SCI(Web of Science), IEEE, ASTM, Taylor & Francis, ProQuest, Wiley, SpringerLink, PubMed and SAGE. The research objects, experimental equipment and survey results are investigated in this review, in which twenty-four different textiles and seven different test methodologies are involved. The test methodologies include five kinds of performance tests and two kinds of observational studies. Two studies showed that the particular fabric was helpful to reduce the pressure on the skin surface, and twelve studies revealed that the multi-layer fabric with good air permeability, heat dissipation and moisture dissipation was helpful to prevent pressure injury. This review confirms the correlation between the fabric properties and the occurrence of postoperative pressure injury in wheelchair users. Further experiments are needed to reasonably integrate the fabric characteristics of pressure injury prevention into the mass-produced pressure injury prevention clothes for wheelchair users.展开更多

The surface change of fabrics before and after abrasion was stu-died by means of scanning electron microscope. With the increasing number of cycles, the re-covery behavior of the fabrics studied in tensile, shear and bending deformation decrease, theantibuckling ability lowers, the friction coefficient increases. The geometric roughness de-creases during the first step of abrasion then enhances with further abrasion. The influence ofabrasion on mechanical properties of the pure wool fabric are larger than that of blend fabric.展开更多

After LTP treatment, the low stress mechanical properties, surface properties and thermal properties of the fabrics were investigated by kES-F (Kawabata Evaluation System) Instruments composing of KES-FBI for tensile and shear property measurement, KES-FB2 for pure bending measurement, kES-FB3 for compression measurement, KES-FB4 for surface friction and surface roughness measurement, and KES-F7 for thermal property measurement. The first four instruments were used for investigating the charaeterlstlc aspect related to fabrle hand while the last one was mainly for the fabric comfort. The properties of LTP treated fabrics under the effect of different gases were compared with the untreated fabric quantitatively.展开更多
