    The common methods for testing yarn hairiness in laboratories are the photoelectric measurement method and the projection counting method. In order to verify the consistent of the results which obtained by these two methods? Which method provides values closer to the true situation of yarn hairiness, this paper compares and analyzes the two methods. The results showed that: the photoelectric measurement method can only provide the pH value of hairiness, but it is more accurate than the projection counting method. The projection counting method can measure the values of hairiness of different lengths and obtain more detailed parameters of hairiness, which can be used to analyze and control the real-time quality of the production line in a timely manner.

    Per- and polyfluoroalkyl substances (PFAS) are widely used in textiles for waterproof and oil-repellent functions, but their persistence and toxicity have led to stricter global regulations. This paper reviews detection methods for PFAS in textiles, including gas chromatography-mass spectrometry (GC-MS), liquid chromatography-tandem mass spectrometry (LC-MS/MS), oxygen bomb combustion-ion chromatography (IC), and online combustion-IC. The principles, applications, advantages, and limitations of each method are analyzed. LC-MS/MS is the mainstream due to high sensitivity, while combustion-IC is suitable for total fluorine screening. Future trends require developing high-sensitivity and rapid screening methods to meet regulations from the EU, US, etc., promoting green transformation in textiles.

    In response to the issue of data instability caused by variations in manual sample placement proficiency during traditional cotton short fiber content testing, an automated sample placement device has been developed. The device employs a fully integrated servo motor drive system, with upper computer software and a programmable logic controller (PLC) as the core control units. By integrating CANopen and RS485 communication networks and combining a pneumatic control module, it achieves automatic sliver arranging, clamping, and positioning functions. This study focuses on conducting comparative experiments to quantitatively analyze the differences in testing result stability between automated and manual sample placement. The experimental results demonstrate that this automated device significantly reduces random errors introduced by human operations, with both the repeatability standard deviation (SD) and coefficient of variation (CV) of the test results being markedly superior to those of manual operations. This automated sample placement device provides a feasible solution for further enhancing the stability of testing data.

    This study systematically investigates the influence mechanism of the interaction effects between down loftiness and filling density on the thermal insulation performance of down-filled apparel. Four groups of white duck down with similar down content (77.0%, 86.0%, 88.5%, 90.0%) but significant loftiness differences were tested using a flat-plate thermal insulation analyzer (per GB/T 35762—2017) across 11 filling density gradients (60 g/m2~210 g/m2, 15 g/m2 increments). Key findings reveal: Minor loftiness differences (0.6 cm) only enhance thermal resistance at high filling densities (≥180 g/m2), e.g., 4.5% improvement for 77.0% down content group; Moderate differences (1.0 cm) consistently improve insulation (average +3.2% thermal resistance for 86.0% down group), though compression at 210 g/m2 diminishes gains; Large differences (1.6 cm) boost thermal resistance by 8.1% at low filling densities (≤105 g/m2) for 88.5% down content, but excessive compression at high densities reduces thermal resistance by 2.3%; High-loft down (19.3 cm) achieves equivalent insulation at 165 g/m2 to conventional down at 180 g/m2, enabling lightweight design. The research uncovers a critical interaction between loftiness and filling density. We propose an industrial optimization principle: prioritize high loftiness for low-density fills; avoid over-compression in high-density applications. This framework supports balanced performance enhancement and cost efficiency in down apparel production.

    In this paper, a method for assessing the color fastness to rubbing of textiles is proposed to solve the subjective errors caused by manual assessment, which enhances the objectivity of the assessment. The method takes the sample image after the color fastness to rubbing test as the research object, uses machine vision processing technology to segment the image wear area from friction cloth as learning samples, and then constructs a color fastness rating model by training a LeNet-5 convolutional neural network for rapid grading. The experimental results show that the accuracy of this method for assessing the level of staining on friction cloth can reach 99.5%, effectively reducing the assessment error caused by human factors and improving work efficiency.

    In response to the issues of incomplete dissolution and fibre damage that frequently arise in the quantitative analysis of cotton/Lyocell blended fabrics using the formic acid/zinc chloride method, as well as the significant measurement errors caused by variations in cotton fibre diameter in the longitudinal physical method, a quantitative analysis method based on the cross-section of a single yarn has been proposed. A comparison was made of the test results of the formic acid/zinc chloride method, the longitudinal physical method, and the cross-section method. The findings suggest that the cross-section method boasts considerable advantages in terms of detection accuracy, result objectivity, and method applicability. Future research could combine machine learning to achieve automated quantification, with the potential to further improve efficiency and universality.

    The influence of extraction conditions (sampling length, heating temperature, heating time and oscillation rate) on the determination results of formaldehyde content in three types of hair products was studied by using spectrophotometry. The results showed that the sampling length had little effect on the formaldehyde content of chemical fiber hair products and human hair products. The extraction heating temperature and heating time were the main factors affecting the release of formaldehyde, especially for human hair products and cowhair products. The oscillation rate had a certain promoting effect on the release of formaldehyde from hair products, but it was not as significant as the extraction heating temperature and heating time. Human hair products were the most sensitive to the heating temperature and heating time, followed by wool hair products, while chemical fiber hair products were almost not sensitive. In the determination of formaldehyde in hair products, it is recommended that the sample length be 10 mm, the heating temperature be 60 ℃, the heating time be 30 min, and the oscillation rate be 200 r/min.

    This paper reviews the data stream collection and application in the process from cotton harvesting to ginning in the United States, and establishes a prediction model aimed at quantifying the impact of fiber quality and seed cotton variety characteristics on ginning rate by standardizing and integrating multi-source heterogeneous data, such as cotton bale identification, fiber quality, and agronomic traits. Studies have shown that cotton fiber quality attributes, such as impurity content, micronaire value, reflectance, and yellowness; and seed cotton variety characteristics, including cotton fiber percentage, bract hair, moisture content, and fiber density, are all key factors affecting the ginning rate. This paper systematically summarizes the relevant data stream architecture, the mechanism of action of key influencing factors, and modeling methods, with a view to providing references for the intelligent upgrading and processing efficiency optimization of China's cotton industry.

    This study employed pure cotton yarn as the substrate, using cerium ammonium nitrate as the initiator, itaconic acid as the functional modifier, and ferric chloride with ammonium persulfate as the oxidizing agents. Through in-situ polymerization, conductive polymer coatings of polyaniline (PANI) and polypyrrole (PPy) were synthesized on the cotton fiber surface, with systematic comparative analysis of their electrical conductivity properties. Scanning electron microscopy (SEM) observations revealed that both polymers successfully coated the fiber surface in granular morphology. Conductivity measurements using the SDM3055X-E digital multimeter showed that the resistance of PANI-and PPy-coated cotton yarns first decreased and then increased with itaconic acid concentration, reaching minimum values at 0.18 g/L. The PANI-coated yarn exhibited a resistance of 0.08 MΩ, while the PPy-coated yarn demonstrated 0.004 MΩ. Experimental results confirmed that this in-situ polymerization method effectively enhances the conductivity of cotton yarn, with the prepared conductive yarns showing promising applications in smart wearable devices and flexible electronics.

    From the 1950s to the 1980s, Shandong women's embroidered garments-represented by the renowned "Peacock" brand-stood as exemplary products in China's arts-and-crafts export industry. The design logic and system behind this successful brand remain underexplored. This research aims to summarize the concrete application patterns of floral motifs in women’s clothing during the mid-to-late 20th century, thereby filling gaps in the understanding of design history in that specific period. It seeks to provide historical reference and inspiration for contemporary Chinese women's fashion design-particularly in integrating traditional craftsmanship, cultural significance, and global market appeal. Drawing on first-hand archives and physical artifacts from the Shidao Embroidery Factory in Rongcheng , this study examines how these garments integrated floral motifs with Lu embroidery techniques to create a fashion style that embodied Chinese cultural aesthetics while achieving strong international market acceptance. The research reveals that their success stemmed from a well-developed "design-production" collaborative system: in creative development, a workflow of "natural sketching - artistic transformation-craft adaptation" was established; in visual composition, a rational method of "deconstructing and reorganizing motif elements" was formed; and in implementation, a highly unified logic of "motif-style-craft-market" was consistently followed. The research identifies the underlying principles governing the use of floral patterns in women's clothing from the mid-to-late 20th century, offering a valuable historical frame of reference for contemporary Chinese fashion brand design.

    product quality and safety risk prevention and control is the core proposition of the modernization of market regulation. To build a scientific and perfect risk prediction and prevention and control mechanism, we need to promote the system from three dimensions of risk identification, prediction and early warning and collaborative disposal, and establish a multidimensional risk classification system by integrating multi-source risk information, which can accurately describe the generation mechanism and transmission law of quality and safety risk. Using digital intelligence technology to build an early warning model to achieve dynamic monitoring and accurate prediction of risks, form a prevention and control pattern of multi-agent collaboration and whole process closed-loop management, and promote the transformation of regulatory mode from post disposal to pre prevention. This mechanism innovation provides a systematic solution for improving product quality and safety governance ability, protecting consumer rights and interests, and promoting high-quality industrial development.
