Antibacterial wound dressings are promising materials to treat infected skin wounds, which greatly affect the wound-healing process. In this study, tannic acid (TA), a natural antibacterial agent, was successfully loaded by electrospinning into poly(caprolactone) (PCL) fibers in high concentration. It is suggested that addition of TA beneficial for producing uniform and continuous PCL nanofibers. Hydrogen bonds existed between molecules based on analysis FTIR spectra DSC results. The...

Traditional halogenated flame retardants (FRs) have been severely hindered because they are toxic and hazardous carcinogenic byproducts during their application. In this study, we present a biobased FR composite consisting of cellulose nanocrystals (CNCs) modified with melamine (MEL) phytic acid (PA) through successive grafting electrostatic adsorption processes. It was found that the CNC/MEL/PA nanocomposite had noticeable highly improved thermal blocking performance nanofibril aerogel,...

Unclear light propagation in mixed fibers has resulted unachievable masses of primary fibers, particular thin two-mixed fiber assemblies for decades. Hereby, a modified medium addition theorem the Kubelka-Munk transmission model is proposed to address this issue. This was constructed by introducing transfer function common ones on scattering coefficients, and such takes both mass proportion each component reflectivity material into consideration. opens up new avenue understanding possible...

There is a complex interaction between primary fibers in pre-colored fiber blends, which leads to the impracticality of Duncan’s additive theory single-constant Kubelka–Munk (KM-1) model, resulting poor accuracy for color prediction. This paper builds an optimized combined spectral calibration model based on KM-1 function solve this issue. proposed involves colored and non-colored parts with trained coefficients, was established achieve good matching predicted actual ratio absorption...

A modification of the two-flux model Kubelka-Munk was proposed for description light propagating through a fiber-air mixture medium, which simplified fibers' internal reflection as part scattering on total fiber path length. series systematical experiments demonstrated higher consistency with reference quantity distribution than common Lambert law fibrogram used in textile industry did. Its application measuring cotton fiber's length to be good, extending its applicability wool fiber, is...

The dual-beard image method, which has been developed in recent years as a fast and economical method for fiber length measurement, consists of specimen preparation, processing, fibrogram extraction, parameter calculations. However, one the shortcomings this is that it can only produce extremely limited parameters such mean length, coefficient variation, modal quality (UHML, upper half length). This study introduces new algorithm converting into distribution histogram be used to calculate...

This paper introduces a new developed wool fiber length imaging measurement instrument, named the random-beard image method, an applied fibrogram method of measurement. It includes four parts, namely beard preparation, acquisition and fibrograms parameter calculation using dual Hauteur (mean biased by cross-section fibers). To check accuracy built international standard Almeter100, was used as reference for comparison. Hence, 10 kinds fibers were measured with both methods results showed...

The random beard image method is a newly developed fiber length measurement with the advantages of speed, reliability and low cost. This paper proposed methods acquiring an accurate stable fibrogram from transmission based on derived Kubelka–Munk theory. In dual-beard preparation process, optical properties short region in were changed by napping effect. To solve this problem, imitating experiment five types wool fibers was designed to obtain coefficient maximum value fibrograms 1.03....

Negative Poisson's ratio textiles have expanded deformation behavior and special mechanical properties under tension. According to the previous research, negative effect of fabrics was always lower than yarns. The main reason that yarns showed little structural because fabric structures. In this study, chain stitch structure with as inserted weft were designed prepared. yarns, symmetrical parallelization arrangement density on tested analyzed. results similar in fabric. When knitting loops...

Texture represents the surface quality of fabrics, which is one key factors for textiles design. Fabric texture can be perceived via sensory perceptions, like vision and touching, causing different psychological feelings emotions. This paper aimed to model correlation between fabric textures evoked emotions through perceptions. Firstly, 20 subjects were required make evaluation on 10 samples, rating induced visual visual-tactile Then, differences in analyzed. The results showed that only by...

A modification of the two-flux Kubelka-Munk (K-M) model was proposed to describe energy conservation scattered light in colored mixed material with a defined photometric, which is applied for relative quantity distribution each monochrome component material. series systematical experiments demonstrated higher consistency reference than common Lambert-Beer (L-B) law. Its application fibrogram measuring cotton fiber's length be good, extending its applicability white and dark blended fibers,...

Insufficient studies of reflectance and fluffiness effects on optical density caused large derivation limited the application fibrogram methods in colored cotton fiber length tests for decades. A coupled method was proposed here to solve this issue, named reflectivity algorithm random-beard image method. In algorithm, a defined theoretical declared with an iteration linear analysis derived Kubelka–Munk law, which satisfied its assumption excluding reflected light at interface air. Meanwhile,...

Abstract Fiber length is one of the essential and tricky-to-get characteristics colored cotton fibers, which affects spinnability quality blending yarns. Based on optical theory structure traits fiber assemblies, an method named Random-Beard Image Method (RBIM) was proposed for measuring linear density distribution, fibrogram, dyed natural beards. This involves a new two-level prediction model reflectance algorithm beard bulkiness. Fibrograms 22 different samples in total were tested to...
