China's Best Seamstress: Hundreds of Thousands of Wedding Clothes, Spend Tens of Thousands of Hours!

Original Title: China's Best Seamstress: Hundreds of Thousands of Wedding Clothes, Spending Tens of Thousands of Hours! Beauty is not only beautiful, but also because of people "The most beautiful dress in the world is the wedding dress, and the most beautiful woman in the world is the bride. I think every Chinese girl can wear a Chinese wedding dress and get married beautifully." She is called "Chanel of China". She is the royal costume designer of Zhang Ziyi, Dong Qing and Fan Bingbing. She was the first person Apple CEO Cook met in China this year. In 2016, she became the first Asian designer to hold a show at Gaoding Fashion Week in France. She is Guo Pei, the first person in China's advanced customization. The first time I heard Guo Pei's name was in April this year. She was named one of Time magazine's 100 most influential people in the world. Expand the full text At the same time, she was selected by Xi Dada and Wang Jianlin. And Tu Youyou, who won that Nobel prize last year. Nowadays, Guo Pei has been struggling in the field of fashion design for more than 30 years. It is a "living dictionary" to witness the development of modern Chinese clothing. Give up millions of annual salary to do Chinese design In 1967, Guo Pei was born in an ordinary family in Beijing. He has not been exposed to knowledge related to clothing and design since childhood. In 1982, she graduated from technical secondary school. He was admitted to Beijing Second Light Industry School. They are the first batch of fashion design students in China. He became a "tailor" in the eyes of his neighbors. In the environment of the 1980s, Chinese people have no concept of fashion design. Guo Pei became one of the first people to eat crabs. After graduation, she was assigned to the designer of the children's clothing factory. From design, assembly line production to ready-made clothes, Learn and accumulate more professional knowledge in practice. Guo Pei became a real "tailor". " Every designer is eager to realize his own design. But many designers can draw it, but they can't do it. With his own efforts and talent, In 1989, she entered Tianma Fashion, the earliest fashion company in China. And become the chief designer. At that time, more than 90% of the company's products were designed by her. It has created a marketing success of 3.9 billion yuan. Tianma brand has become one of the top ten brands in China. When her designs hit the market, It can always become a new fashion trend. Guo Pei was also awarded "Top Ten Designers in China" However, success did not make her happy. She's not even happy with herself. In those years, she didn't want to go to the mall. Even if you go, you will bypass the clothes you designed. In my mind, those designs are not up to my standards. I always want to pursue a kind of perfection, not for anyone. Just fulfilling one of my desires as a designer, Make a dress that can't be sold. In the 1990s, Most of the designs in China are copied from abroad. Simple imitation, mass assembly line production,keychain tape measure, It can't be called design at all. One must not be haughty, but not without haughtiness. Deep in Guo Pei's heart, There was always a voice reminding her: Why can't we make designs that belong to China? In 1997, Guo Pei gave up the good "money" of the chief designer. He resigned willfully and started his own business. He opened his own studio, Rose Square. It has embarked on its own road of Chinese advanced customization. At Rose Square, The essence of advanced customization is embodied in the design of excellence in every detail. Every piece of clothing is tailor-made and tailor-made. To achieve Chinese dress design, No one knows how difficult the road is. She has to go to the theatre to watch performances after work. Learn about the costumes on the stage and collect more images and pictures. When learning to make a real traditional cheongsam, She bought more than ten antique cheongsams. Take it all down and study the direction of the warp and weft. Embroidery is the biggest highlight of Rose Square. For Guo Pei, hardship is not the most difficult. The most difficult thing is that fewer and fewer people can embroider. Fewer and fewer people are willing to sink down to learn embroidery. This skill, which has an ancient history of more than two thousand years,large print tape measure, is inherited. It broke her heart. Embroidery technology has not been widely handed down. In order to be able to embroider the most beautiful patterns, Better presentation design effect She can only look for a needle in a haystack to visit these embroidery workers who have been forgotten and neglected by the times. Heaven pays off. The first embroiderer in the studio, She found it in the fields in the countryside. In this way, Guo Pei followed suit. Use the most stupid way to find the second, third, first.. Up to now, there are 300 skilled embroiderers in her Rose Workshop. Some things can only be said in one sentence, but it takes a lifetime to do it. Guo Pei cherishes these embroiderers and gives them five or six times the salary. For them, there is only one requirement: the heart must be calm. Embroidery is a lonely skill. If you want to achieve a zero-defect boutique, Peace of mind is the foundation, but it is also the most difficult. Some embroidery techniques are complex. Sewing is too thick, the needle is difficult to penetrate, must rely on pliers and tweezers to pull out. Every stitch, it pricks the hand.. This is not something that ordinary people can bear and insist on. "Pursuing beauty and inheriting craftsmanship is actually a belief." It takes time, patience, and dedication to nurture. Guo Pei and her more than 300 embroiderers, Defending the last pride and dignity of ancient handicraft. In Guo Pei's private museum in 798 Art District, there is a priceless "advanced customization". It was made by 100 embroiderers for nearly three months and took the whole team more than 50000 hours to make. This super luxurious work of art has also created many digital miracles: 28000 silver buckles embroidered by human hands, thousands of shafts of European silver thread, and a weight of more than 200 kilograms.

Private customization, making clothes for celebrities On 5 May 2015, The Metropolitan Museum of Art Gala, International superstar Rihanna (Rihanna) wore Guo Pei's "One Thousand and Two Nights" couture dress "Rhubarb Robe" on the red carpet of Met 2015. Stunning the entire fashion world, It received hundreds of millions of hits that day. In fact, among Guo Pei's clients, More than 1/3 of them are stars at home and abroad. So far, Guo Pei has designed costumes for the hosts and actors of the Spring Festival Gala for ten consecutive years. Dong Qing, Zhou Tao, Li Sisi, Song Zuying, Li Yugang and other Spring Festival Gala costumes are all designed by herself. On the eve of the 2008 Spring Festival Gala, The editor-in-chief of Harper's Bazaar took Zhang Ziyi to Rose Square to find Guo Pei to design the dress. And Zhang Ziyi's Spring Festival Gala performance "Tian Nu San Hua" shocked the audience! The audience was full of praise for her dress. It is speculated that it comes from the hands of international famous teachers and is worth millions. In fact, the dress was lent by Guo Pei to Zhang Ziyi. Years later, Zhang Ziyi went to the United States to attend the Grammy Awards Ceremony. At the event, she wore a short yellow chiffon dress designed by Guo Pei. Zhang Ziyi's dress on that day attracted considerable media attention. It has won numerous praises. In this year's star reality show of Hunan Satellite TV, On the stage of "Here We Come", Guo Pei once again conquered the public's eyes with his design. In July this year, Guo Pei was invited to hold a show at Gaoding Fashion Week in Paris. He became the first Chinese designer to hold a personal show here. With the theme of "Meet", Clothing absorbs the essence of ancient Chinese tradition. A stitch, a plain brocade, It has achieved the ultimate beauty of China. It has become the founder of Chinese Gaoding Museum-level collections. It has not only changed the world's understanding of Chinese fashion, It also makes Chinese clothing go to the world. Since then, advanced customization is no longer exclusive to the West. Every Chinese girl can afford to wear Chinese wedding clothes. Whether it is the Spring Festival Gala or the international stage, But Guo Pei still felt that. These do not meet the most beautiful standards in her heart. She has been looking for a dress that can withstand the passage of time and the change of trends, and still be amazingly beautiful. Maybe it's doomed in the dark. A mother-in-law from Hong Kong let Guo Pei find the answer. Her mother-in-law came to her with a traditional Chinese wedding dress to modify. "This is the Chaozhou embroidered wedding dress I wore more than 50 years ago." Now, I hope my daughter-in-law can wear this wedding dress. From ancient times to the present, Wedding dress is the most important dress in every girl's life. It must be tailored and hand-sewn to show its preciousness and uniqueness. It is the best blessing for parents to give their daughters when they get married. Their deepest love, reluctance and wishes for their daughter were all gathered in the wedding dress. And hope that this blessing and expectation can be passed on and become eternal. On her mother-in-law, Guo Pei saw: A wedding dress, with blessings, has gone through three generations. This gave Guo Pei inspiration. From that day on, Guo Pei found the most beautiful clothes in his heart: Chinese traditional wedding dress. In Rose Square, Guo Pei has a requirement for the embroidery workers who make "Chinese wedding clothes": If you are in a bad mood today, please don't move your needle and thread on the wedding dress, because your mood will certainly affect the wedding dress. The person who makes the wedding dress must have a good mood and a peaceful state of mind. Needle and thread, closely sewn are all blessings to the bride.

The person who makes the wedding dress must have a good mood and a peaceful state of mind. Needle and thread, closely sewn are all blessings to the bride. In fact, in recent years, many stars'wedding clothes have been designed by Guo Pei. From drawing design, plate making to accessories matching, pattern combination to fabric selection and manual sewing, it has been widely used. She is very strict in every step and every detail. Because of the exquisite materials used in traditional Chinese wedding clothes, In addition, it is all hand-embroidered. Often time consuming, Sometimes hundreds of workers, for a few months, Only one wedding dress can be completed. But each one is unique. Each piece is the painstaking effort of Guo Pei and the 300 craftsmen of Rose Square. Liu Shishi's colorful gold thread embroidery with dragon and phoenix patterns took 7412 hours; Wu Qilong's golden dragon embroidered silk wedding dress took 640 hours. (The baby's wedding dress took 798.1 hours.) Chen Yanxi's orange phoenix dress took 1880 hours. It took Chen Xiao 3,985 hours to get the Purple and Gold Robe.) Perhaps some people will say: Only rich people can afford to wear her clothes. She was worried that her Chinese wedding dress would also take a high-set route. But in fact, her biggest dream is, So that every girl can wear Chinese wedding clothes. Guo Pei said: "My Gaoding can not be commercialized, it is the purest kingdom I left to myself, but the wedding clothes must go to business.". Because my wish is that every Chinese girl can afford to wear Chinese wedding clothes in the future. Guo Pei said: "My Gaoding can not be commercialized, it is the purest kingdom I left to myself, but the wedding clothes must go to business.". Because my wish is that every Chinese girl can afford to wear Chinese wedding clothes in the future. For this reason, Guo Pei runs schools, factories, embroidery classes and trains craftsmen. The design is newer and more beautiful. This is just to minimize the cost of each wedding dress. Now, her wedding dress has been reduced from more than 100,000 yuan to 20,garment measuring tape,000 yuan a set. This is her most sincere wish to every Chinese bride.

Original Title: Brief Introduction to the US FDA Guidelines on Key Points for Non-clinical Evaluation of Medical Devices Containing Nitinol Brief Introduction of FDA's Guideline on Nonclinical Evaluation of Medical Devices Containing Nitinol In October 2020, FDA of the United States issued the Guidelines for Non-clinical Evaluation of Medical Devices Containing Nitinol, which elaborated the key points of technical review of medical devices containing Nitinol. The contents of the Guidelines are briefly introduced as follows. I. Basic Concepts Nitinol is a near-equiatomic alloy of nickel and titanium, which has the properties of superelasticity and shape memory, and is widely used in cardiovascular devices such as heart stents, valves, guidewires, and other fields of medical devices. Compared with traditional metals such as stainless steel, titanium or cobalt-chromium alloys, nickel-titanium alloys have complex properties and are susceptible to many factors such as alloy composition, thermal processing, surface treatment, corrosion of biological tissues and so on. When evaluating its safety and effectiveness, it is necessary to focus on thermodynamic properties, process sensitivity and so on. II. Key points of technical evaluation (I) Basic information 1. Material composition If the material of the nickel-titanium alloy used in the device conforms to a recognized standard, it shall be specified in the application (e.g., ASTM F2063). If the material does not conform to a recognized standard,titanium plate gr7, the composition of the material shall be defined and its properties shall be described. 2. Manufacturing process The production process flow diagram shall be provided, especially the thermal process, surface treatment steps, final cleaning steps, etc. 3. Superelastic/shape memory properties At operating temperatures, superelasticity or shape memory can be achieved by adjusting the composition and heat treatment of the nitinol alloy. Due to the large difference in properties between the two, the applicant should specify in the application which properties (superelasticity or shape memory) of the nickel-titanium alloy are used. 4. Deformation temperature The change of temperature will affect the mechanical property of nickel-titanium alloy. It is recommended to specify the phase transformation temperature of the finished product in the data. Refer to ASTM F2004 and ASTM F2082. (II) Mechanical test 1. Key points of experiment It is recommended to explain the control mode adopted for mechanical testing; for deformable implantable devices,3d titanium wire, it is recommended to consider clinical deformation and temperature drift before mechanical testing; mechanical testing should be carried out at actual clinical temperature; if fatigue testing is carried out, it is recommended to use clinically relevant solvents (such as PBS); If the shape memory properties of the device are utilized, it is recommended that shape memory testing be performed at clinical temperatures and service cycles, and that functional properties and device integrity be evaluated. 2. Stress calculation/strain analysis If a computational analysis is performed, an appropriate metal model should be used to correctly reflect the thermodynamic properties of the nitinol alloy. A material model may be selected by reference to ASTM F2516. The applicant shall verify the calculation model. If the device is subjected to a cyclic load test, the fatigue safety factor shall also be calculated. Expand the full text (III) Corrosion resistance test 1. Pitting Corrosion of nitinol alloys can result in the release of nickel ions and affect the integrity of the device. The corrosion resistance depends on the manufacturing process and surface treatment. Pitting corrosion testing is recommended in accordance with ASTM F2129. 2. Release of nickel ion If Nitinol devices do not meet the accepted criteria for corrosion resistance, or do not use a proven surface treatment process, a nickel ion release test should be considered. Refer to ASTM F3306 for test methods. 3. Galvanic corrosion If Nitinol devices are expected to be in contact with dissimilar metals, consideration should be given to performing a galvanic corrosion test, as recommended in ASTM F3044. (IV) Biocompatibility It is recommended to refer to ISO 10993 -1 for biocompatibility evaluation. If a nickel ion release test is performed, refer to ISO 10993 -17. (V) Label information It is recommended that the label clearly indicate that the device contains nitinol, suggesting that it may cause allergic reactions in patients, nickel titanium wire ,Titanium welding pipe, especially in long-term or permanent implanted devices.
