Study on the structure and properties of modified silk with ultraviolet absorbent北大核心CSCD

The silk fiber has an irreplaceable position in textile fibers and related silk fabrics have the advantages of light and airy texture good moisture absorption and breathability comfort in wear etc. It is also widely used in other fields such as the biomedical sector. However silk also has its own limitations poor light resistance and susceptibility to ultraviolet light especially the ultraviolet light of 290-400 nm wavelength in daylight such as under which condition it is prone to yellowing and photodegradation. The yellowing of silk is due to the photo-oxidation of tyrosine and tryptophan in silk protein under the action of ultraviolet light from sunlight and due to the production of yellow substances which affects the whiteness of silk. In addition from the molecular structure of silk most of the amino acids susceptible to UV light are distributed in the amorphous region. As the amorphous region is affected the structure of the crystalline region is also gradually relaxed the local degradation begins and the silk protein macromolecule chain is cleaved which leads to the decrease of the mechanical properties of silk fibers and accelerates the aging of silk fibers and fabrics. Therefore it is necessary to modify the silk products outside the anti-purple line. The current methods used to modify silk are mostly for post finishing modification including coating impregnation and chemical grafting methods but these methods often affect the original color or feel of the fabric and the durability of the modified effect is also poor. The feeding method is a green method to obtain modified silk by spraying mulberry leaves or artificial feed mixed with modifier which is ingested by silkworm and transferred to silk gland. In this study five aminobenzene UV absorbers were used as exogenous additive food for silkworms. The effect of molecular polarity on the transport of modifiers to silk glands was investigated and their effects on silkworm development and silk structural properties were studied. It was found that the aminobenzene UV absorbers were more easily transferred to the central silk gland silk glue and less to the posterior silk gland (fibroin). 4-dimethylaminobenzoic acid was found to be the highest in the posterior silk gland with a content of 3. 27 μg / strip. The cocoon width and cocoon quality of this group were significantly lower than those of the control group and the silk gum content was increased when this group was used as the study object. Compared with the control group the relative content of β-folded structure and crystallinity of the silk in the addition feeding group decreased slightly. The silkworm silk in the feeding group showed a certain UV absorption ability. After 330 h UV irradiation the breaking strength and elongation of the control group decreased by 48. 95% and 43. 52% respectively while those of the feeding group decreased by 42. 03% and 34. 18% respectively. In this paper UV absorbers were added to silkworms to obtain modified silk mainly focusing on the transfer of the modifier to the silk gland and the structural properties of the modified silk only for the most UV absorbers to enter the silk gland of the posterior group of silk. Other properties of the modified silk such as washing resistance have not been studied and some more in-depth studies are required. For instance it needs to be studied in depth for the limited absorption of exogenous additives by silkworms additive food's being not always absorbed by silkworms and transferred to the silk gland and the mechanism of action between the additive food and silk protein after the former's entering the silk gland. © 2022 Authors.

2.The Production of Wool

The term "Wool" is generally understood to refer to the fleece obtained from sheep, Sheep was probably one of the first animals to be domesticated and wool was one of the natural fibres that mankind earliestly and successfully made into a fabric, as far back as the remote stone age. In the beginning primitive sheep were covered with hair, and wool was merely a soft, slight down next to the skin, as is still true of some native unimproved sheep of present time. Because of the many environmental adaptions, it is impossible to determine the many original breeds of sheep contributing to modern types. Most fleece wools for textile use can be classified on the basis &f fineness and length into one of five types. (?)ine wool, medium wool, long wool, crossbred wool and carpet, or mixed wool. Only the Merino family can be classified as fine wool breeds. The ancestor of the finest wool —     

Research on image segmentation of Miao costume patterns based on the RSKP-UNet model北大核心CSCD

The Miao nationality is the sixth largest ethnic group in China which has a history of thousands of years. It has created a unique material culture and spiritual culture in its development process and the Miao costume is a highly condensed collection of the material and spiritual culture of the Miao nationality. As one of the unique symbols of Miao culture the Miao costume has profound cultural heritage and cultural connotations. The patterns of the Miao costume are particularly eye-catching as they not only symbolize the wisdom of the Miao people in thousands of years of production and life but also symbolize the pursuit of the good spirit of the Miao people. However under the impact of modern pop culture and foreign culture these cultural symbols are gradually disappearing. In order to protect and inherit them the Miao costume pattern segmentation has become the most important work. However the Miao costume pattern segmentation is quite difficult. At present there are few studies on the extraction classification identification and preservation of the features of Miao costume pattern segmentation. With the excellent segmentation performance of the U-Net model and the advantages of easy deployment the paper improves the basic structure of the U-Net model and proposes a Miao costume pattern segmentation algorithm based on the RSKP-UNet Residual Selective-Kernel Parallel U-Net model. The algorithm adds Residual modules in the encoder part of the U-Net model to improve the feature extraction capability of the model and embeds the SKNet modules and ParNet modules in the decoder part to enhance the feature expression capability of the model. The paper uses evaluation metrics to measure the segmentation performance of the model and compares it with four segmentation models based on deep learning. The paper not only combines the current research focus-deep learning and attention mechanism but also introduces the Lovász-hinge loss function to effectively solve the problem of class imbalance in the Miao costume patterns. The RSKP-UNet model is better than other models in various segmentation indicators. Compared with the benchmark model U-Net the Dice coefficient IoU precision recall and accuracy are improved by 6. 98% 11. 07% 2. 89% 6. 75% and 3. 92% . The segmentation algorithm proposed in this paper realizes the extraction of the element content of the Miao costume patterns through image segmentation of Miao costume patterns which can be used to build the Miao costume pattern database in this way thus helping designers relevant researchers and organizations to provide research foundation and completing the protection and inheritance of the Miao costume culture. The paper also provides some reference for the segmentation research of other minority costume patterns. © 2022 Authors. All rights reserved.

Analysis on the shape and structure of Mongolian traditional Gu Gu crowns in the illustrations of the Jāmi' al-Tawārīkh in the National Library of France北大核心CSCD

Jāmi' al-Tawārīkh is a detailed history book of Mongolia compiled by the prime minister Rashid al-Din under an order issued by Ghazan Khan in 700 of the Islamic calendar (1310 - 1311 A. D.). After the book was finished the royal family invested a great deal of manpower material and financial resources to draw its illustrated edition which was completed between 1306 A. D. and 1314 A. D. In this period Persian miniatures had strong Mongolian characteristics. The facial shapes of the characters showed the image characteristics of Mongolians and the clothing styles and patterns on the clothes also had the characteristics of Mongolian and even traditional Chinese costumes. Among them Jāmi' al-Tawārīkh in the National Library of France was drawn between 1425 A. D. and 1430 A. D. There are 15 Persian miniatures in the book that illustrate the Gu Gu crowns worn by aristocratic women of Mongolia which were the headgear favored by women of the ethnic group at that time and were very popular. The Gu Gu crowns in the illustrations are rich in color and clear in structure which provide precious and detailed historical image data for us to study the shape and manufacture characteristics of Gu Gu crowns in the Mongolian and Yuan Dynasties. Through reading the pictures we can learn the color pattern shape structure collocation wearing effect and identity of the wearers wearing occasions and other practical problems of the Gu Gu crowns. Combined with the ancient documents and images we can further study and analyze the specific shape and system of the Gu Gu crowns in the Mongol Yuan period the characteristics of wearing and the related cultural connotation behind them. Firstly the 15 illustrated wearing scenes were classified and the wearing characteristics of Gu Gu crowns in different scenes were summarized to find out their regularity. Secondly the characteristics of wearing the Gu Gu crowns in different scenes were compared and the different meanings they represent were analyzed and studied. Finally we concluded the shape characteristics and decorative effect of Gu Gu crowns in the Mongol Yuan period and summarized the cultural implication and national belief represented by Gu Gu crowns as well as the fundamental reason why they were favored by Mongolian women for their enduring popularity. On this basis the correspondence analysis method was used to study the relationship between the formative characteristics occasion of wearing cultural connotation and the identity status and belief of the users. We concluded that the characteristics of the Gu Gu crowns in the illustrations of Jāmi' al-Tawārīkh collected in the National Library of France except for only wearing the hood and crown cape in keeping vigil beside the coffin changed little with the wearing occasions. The shape of the bionic swan showed totem worship the structure features of the square above and the circle below explained the significance of the combination of men and women. It reflects that Mongolians believe in the "Mongke Tengri" Eternal Heaven and the modeling concept based on nature is beyond nature. The structure of being square at the top and circular at the bottom explains the significance of the combination of men and women. The length of crown feathers the number of the ball feathers the hood color and the cape length change showed that the usefulness of Gu Gu crowns was replaced by decoration becoming a symbol of status. In the middle and late period the gold cross pattern appeared frequently in the crown decoration highlighting the identity of many noble women as disciples of Nestorianism. As a whole Gu Gu crowns elongated the human body lines in a towering and beautiful shape making people appear tall and in line with aesthetic characteristics. The luxurious decorative details highlighted the rich and leisure life of aristocratic women and their noble social rank and status in the Yuan Dynasty. The original symbolism took a back seat to the decorative function. This edition of Jāmi ' al-Tawārīkh provides precious image information for the study of the shape and symbolic significance of aristocratic women's headgear in the Mongol (Yuan) period. Through systematic studying and sorting out the structure shape material pattern production technology etc. it can better inherit Chinese traditional costume culture and inherit the traditional costume skills of China. The research results can provide inspiration and innovative ideas for the design and innovation of Chinese national costumes. Under the trend of global integration the exchange of clothing culture among different countries is increasingly close. It is a shortcut for Chinese fashion to go to the world to retain and integrate the characteristics of national clothing. © 2022 Authors. All rights reserved.     

Seoul Food Culture Viewed from High-Class Korean-Styled Restaurants and Korean Female Entertainers in the 1930s

Since Korea-Japan annexation in 1910, Japan has promoted the migration and/or tourism into colonial Chosun （old Korea） as an efficient cultural strategy for extending imperialism into Korean peninsula. In many tour guide books, the gisaeng （Korean female entertainers） was not only a symbol of Chosun tradition, but a main icon of Chosun tourism. The high class Korean-styled restaurants （yorijoem） were established as tourist attraction for Japanese inlanders, with singing and dancing gisaengs, ondol （Korean heating floor） house and Korean authentic cuisine, etc. The aim of this paper is firstly to explore the existential change of gisaengs in the yorijoem through its spatial significance in the 1930s, and secondly to explore the identity of Seoul local food culture and its metamorphosis under the colonial modernity.
