Chen Aihua Technical Director of Shanghai Zhengzhang Industrial Co., Ltd., leader of Shanghai Skill Master Studio, the only laundry master in Shanghai laundry industry, a national washing and dyeing industry expert, and a national senior evaluator. Awarded the National Model Worker
At the end of 2021, at the finals of the former 12th National Vocational Skills Competition for Washing and Dyeing Industry, Chen Aihua, a "laundry god craftsman" who was praised by customers as "hand to hand", appeared on the field again as a referee. She sighed with emotion, "I didn't expect to have today's results, I just wanted to learn a craft when I first entered the industry." "In the past 25 years, she has become more and more engaged, the more she learns, the more fascinated, in addition to practicing washing technology, she also explores equipment innovation, tries process reform, and develops more than 40 kinds of washing solvents to overcome many laundry problems and become a well-known skill master in the laundry industry.
How the Master's Skills are practiced
Chen Aihua's classic laundry case of "hand to stain removal" is often amazing. Two years ago, she was approached by an upscale hotel in Shanghai and asked her to clean a national ceremonial tapestry. The tapestry has been hanging for a long time, covered with floating dust, and the fading is even more serious. Tapestry is wool and linen material, there are thirty or forty colors, wash to prevent decolorization, anti-dyeing, after washing also to fix color, trimming, color patching, coloring... The whole process is like a brush stroke copying, not the slightest difference. This "hard bone" she "nibbled" for two months, and the tapestry re-unveiled surprised everyone on the scene: the pattern was clear, the color was bright, just like new!
A customer came with a BV leather bag worth 300,000 yuan. The bag was contaminated with ink by a quarter from the inside out, and the stains seeped into the outer skin surface. The BV store directly sentenced him to "death penalty", but the customer was not willing, and heard that Chen Aihua of the zhengzhang was very powerful, so he held a glimmer of hope and asked her to help.
BV bag even the inside and outside of the sandwich is made of leather, to ink stains, first of all, the ink should be dissolved, but the ink should be put into the water, and the leather bag should not be put into the water, because the leather is easy to deform when it meets water. Chen Aihua repeatedly pondered with the leather bag, and finally decided to open the bag and clean it in layers from the inside to the outside, so that the ink would not form secondary pollution. Then the stain removal process is used to remove the ink stains on the outer skin surface. After the cleaning was completed, she sewed the bag one by one.
After the repaired BV leather bag is intact, the customer is surprised and happy, and said to Chen Aihua one by one: "I really don't know how to thank you." Chen Aihua said bluntly: "I took the bag apart and washed it, and after washing it, it was sewn up again." The customer didn't believe: "Really? How come I didn't see it? ”
The 2014 CICA Summit was held in Shanghai, during which the flags of the participating countries should be hoisted. The flag is made of tribute satin fabric, soft and silky, because of the long-term folding, the formation of obvious creases. The security demanded that the national flag could not be taken out of the venue and must be ironed on the spot, and Chen Aihua, who received the task, rushed over with an ironing board and an iron.
The national flag is big, the hot plate is small, what to do? On a whim, she spread the thread blanket on the marble steps and made a homemade oversized "hot table". Steam irons cannot be ironed, as there is no dehumidification equipment on site, and if there is still moisture on the flag after ironing, the crease will appear again. She uses an old-fashioned electric iron, controlling temperature and humidity by the sound of water droplets on the iron. Patrol, stew, gently lift, slow move... In one fell swoop, the 108 national flags were as smooth and smooth as ever, and she recreated the unique work of a craftsman with her profound skills. Every time he completed a challenge, Chen Aihua was very pleased, because "every challenge is an experience".
A handkerchief was scalded for three weeks
Kung Fu is all practiced. In 1997, 18-year-old Chen Aihua graduated from secondary school and went to Shanghai Zhengzhang as an intern. "Isn't it just washing clothes?" At that time, she thought very lightly, and when she started to move, she knew that it was not so simple. The first lesson in the industry is a hot handkerchief. Master told her that the hot handkerchief should be flat, the four corners should be kept at 90 degrees, and then folded in half and then in half, and when folded into a new square, the four sides must be straight, and each side must not be exposed. An ordinary handkerchief, she burned for three weeks in a row to pass, but the four corners of 90 degrees still did not meet the standard.
Chen Aihua had a stubbornness, she did not believe that she could not do a good job, from then on she "pierced" into it, carrying an iron every day to practice, and her hands and elbows were often burned red and purple. Practice the iron and practice the fan brush. Fan stem brush is a seiko hand washing tool, brushing need to control the strength of the wrist, keep the surface flat, do not hurt the fabric, can not be like the fan stem has a silky brush marks. Often, someone else was off work, and she continued to brush it over and over again.
Holding the iron, carrying the brush, dry all day, every day when I go home, my arms are tired and sore, and I dare not touch them at night. Chen Aihua cried bitterness, shouted tiredness, and even thought about giving up, everyone's girls are clean and clean in the office, she also wants to find a relaxed job. Parents were ordinary workers, and they believed in the power of craftsmanship, "Besides, where is the sweetness without bitterness?" The encouragement of his parents made Chen Aihua persist.
After settling down, she began to think about dry cleaning techniques. What does it look like to wash the same fabric for a minute? What does it look like to wash for two minutes? What is the difference between the two effects? She found that the knowledge is hidden in the details, "Only if you pay more attention and understand more, can you ask the teacher father with more questions, and can you learn more techniques." ”
Chen Aihua, who loves to study and endure hardships, became the first official employee among interns. After that, she took one step at a time, from the grass-roots salesman to the secretary of the regiment branch. In 2003, the company planned to open a branch store on Huaihai Road, which is now called "flagship store". The leader wanted to choose a young store manager for the store, picked and chose, and locked Chen Aihua. "This girl is down-to-earth, has strong business ability, and can afford to take on this burden!"
That year, 24-year-old Chen Aihua became the youngest store manager of Shanghai Zhengzhang Company.
Huaihai Road is located in a bustling commercial street, busy business, washing clothes often have a variety of "difficult and miscellaneous diseases". Some stains are difficult to wash, or washed off clothes also spent. There are also some severe fading, and there is a large area of color difference, which is very troublesome to recover. How to remove stains without hurting the fabric? How to pluck the color and fix the color? Chen Aihua began to lead the team to develop the "stain removal" process.
"We bought hundreds of fabrics of different colors and materials, tested them one by one with different potions, and observed the changes in the color of the fabrics." Fabrics have natural fibers and chemical fibers, so it is necessary to learn fiber knowledge; most of the potions are chemical synthesis reagents, so it is also necessary to learn chemical knowledge. During that time, she bought a lot of books and read a lot, "including the professional books left by the masters. In countless tests, her original "stain removal" process has gradually matured.

Chen Aihua's disciples ironed clothes
The new process developed by Chen Aihua was quickly verified by the market. One day, a German customer came to the shop and wanted to wash a Michelin doll costume. The dress was worth 140,000 yuan, the whole dress was stained with black offset, and the clothes themselves were pure white. Before this guest had run to twenty or thirty laundromats in Shanghai, no one dared to pick up, he was discouraged, saying that if he really could not wash, he had to take it back to Germany to wash.
After Chen Aihua inspected it, he found that the difficulty in cleaning this dress was that the fabric had a coating. "There are many methods of degumming in traditional laundries, but ordinary degummants cannot be used on this fabric, and the agent will chemically react with the coating. When the coating is gone, the clothes are wasted. Although it is a "hot potato", Chen Aihua still took it, "with experience, I feel that I have 50% certainty." ”
She first selected a sesame-sized dot on the back of the suture as a sample, dripped the potion, checked how the offset print and coating changed, and then adjusted the concentration and type of agent according to the change, this is not OK, change; that kind of no, then change... Until the fifth type was adjusted, a miracle appeared: the vinyl was printed off, and the coating was not removed! That's great! That's it!
The two-meter-high clothes, hundreds of stains, were treated clean by Chen Aihua, and there was no change in the fabric and no change in the coating. The German guest's eyes widened in disbelief: "You washed this?" He thought that only German craftsmanship could achieve this kind of cleaning effect, but he did not expect that Shanghai could also do it.
Why do you dare to take jobs that others dare not take? In the face of such a question, Chen Aihua always smiled and said: "I am bold and lucky." Of course, she also said bluntly: "In fact, I also do assessment, and I will pick up the number in my heart." ”
Chen Aihua loved to study, and saw that the condensate of the dry cleaning machine in the store was directly discharged, and she felt pity: "The water is clean and has temperature, can it be reused?" "A water tank, a water pump, the water tank is heated, the pump is pressurized, and the dry cleaning condensate is connected to the washing machine, which realizes the recycling of condensate. This set of "dry cleaning condensate recycling energy saving method" was quickly promoted by the industry.
Chemicals should be used when spraying leather, and it is not conducive to physical health for people to face leather. Chen Aihua accidentally saw a car spray room in the Shanghai Automobile Factory, which was operated by a manipulator and no one had to enter. Inspired, she also invented a "leather spray room", the spray room is transparent, with a water curtain, the water can take away the exhaust gas after atomization, people only need to put their arms into it to operate. "Leather spray room" has obtained a national invention patent.
Laundry is very knowledgeable. Chen Aihua edited and wrote industry textbooks and question banks, restored the identification of senior technicians who had been stuck for 23 years; she led apprentices to pass on the art, and the disciples won gold and silver in the national vocational skills competition... Due to his exquisite skills, Chen Aihua became the chief technician of the first batch of laundry engineers in Shanghai. In 2018, she was named a Shanghai craftsman, and in 2020, she was elected as a national labor model.
Asked how to understand the spirit of craftsmanship, Chen Aihua's answer was: "Treat all clothes sincerely, treat them like works of art and 'finely carved', for me, this is the craftsman!" ”
