"No, I have to emphasize a very important point. In addition to plant dyes, ancient fabric dyes were sometimes dyed with mineral pigments such as cinnabar. Therefore, a color fading test should be done before washing. The method is to wet the edges and corners of the fabric with water, and then dip it with cotton
Wipe it to see if there is any color on the cotton. This method is universal." Cheng Zhen said playfully: "Just remember this basic thing. If the color fades, it cannot be washed."
"Okay, it's not difficult to remember this." Luo Tian smiled bitterly: "If the color fades and cannot be washed, then dry cleaning is necessary?"
"Yes, there are many stains that are neither soluble in water nor safe in aqueous solution, so organic solvents must be used to deal with them. Organic solvents used for dry cleaning include: ethanol, acetone, gasoline, benzene, toluene, etc.
When using the above flammable and explosive substances with low boiling points, pay attention to fire and explosion prevention. For safety, it is best to do a small experiment first to confirm that it will not harm the fabric before starting to use it. Whether it is washing with water or dry cleaning with organic solvents, choose and
Using appropriate surfactants will achieve good results." Cheng Zhen said: "To a certain extent, dry cleaning is slightly simpler than wet cleaning, but it is only slightly simpler."
"I don't understand." Luo Tian immediately raised his question: "Generally, ancient fabrics are unearthed with ancient corpses. There should be some processes before cleaning."
"Ah, you discovered it." Cheng Zhen felt a little embarrassed: "I made a mistake in the order of my statements. Yes, the ancient fabrics are all together with the ancient corpses, so we have to separate the fabrics from the ancient corpses at the beginning.
I participated in the cleaning work of an ancient corpse from the Chu State. After the ancient corpse was moved to the museum, it was disinfected, dissected, and examined, and then the unearthed silk clothes were cleaned. After the cleaning was completed..."
"Repair work." Luo Tian had already thought of it.
"Yes, repair and cleaning are just the first step. For most fabrics, there is generally no need for reinforcement, because these collections do not require usable mechanical strength. But for those that are very rotten
For fabrics, if some appropriate reinforcement is not done, they are often broken at a touch. Sometimes for display purposes, it is also required to have enough strength to be easy to pick up and move. Some broken parts should be repaired if conditions permit.
Do some appropriate repair work. Before repairing, you should first analyze the fiber composition, properties, processing aspects, dyeing and other issues of the fabric, and then choose the appropriate method for treatment."
"It's like seeing a doctor, prescribing the right medicine." Luo Tian gave a quite apt metaphor.
Cheng Zhen couldn't help but applaud: "Yes, that's it. Prescribe the right medicine, know the composition, properties, processing technology and other factors of the fabric, and then repair it, so that it can be reproduced perfectly."
"What are your commonly used methods?" The reason why Luo Tian asked this was mainly because he knew that Cheng Zhen had just graduated and had very little practical experience, so he might not know everything comprehensively, so what he wanted to know now was only the most commonly used methods, which Cheng Zhen should have some understanding of.
, at least I participated in a practical operation.
"Well," Cheng Zhen tried hard to remember: "For those silk fabrics such as silk paintings or silk books, the best way at present is to use the traditional mounting method. For those fragile fabrics, silk screens can also be used as a foil.
It can be either single-sided or double-sided. However, because silk threads are not durable and are easily eroded by moths and microorganisms, synthetic fibers (such as Trilon fiber) are now used to repair and reinforce fabrics abroad, which are both durable and durable.
It won’t shrink and can achieve extremely fine repair effects.”
Strangely, Luo Tian thought about it. Prince Zeng's queen's dress was just fixed on the wall without any background. Could it be that some special treatment had been done? I must ask for advice if I have the chance.
"Fragments of fabric can also be preserved between two pieces of special glass or plexiglass. This glass or plexiglass should preferably have the ability to absorb ultraviolet rays. When sandwiching the fabric between pieces of glass, the corners should be padded
Some soft cloth or soft paper, the weight of one side of the glass directly presses on the fabric. When displaying, it should be laid flat and the fabric should not move back and forth inside. The four sides of the glass frame should be sealed with tape or transparent glue to block outside air pollution." Cheng
After I finished speaking, I felt a sense of accomplishment: "How about it, this is indeed my major, right?"
"It's true that there are specialties in the art industry." Luo Tian said: "I will have to ask you for advice often in the future." Regarding antique restoration, Luo Tian learned a lot from Zhu Jingzhi, but they were all about porcelain and ancient books, and they were practical.
It's a pity that he doesn't have much experience and can only stay in theory. His own powers have been proven to be useful in repairing antiques. Perhaps, Luo Tian thought, there are high imitations. As soon as the idea came up, Luo Tian
Tianjiu shook his head vigorously, Gao Fang, master Lu Tai'an said, if you want to be used for it, you must use it in the right way, otherwise you will live up to his teachings.
Lu Tai'an has been a contradictory individual throughout his life. On the one hand, he is very proud of his jade-making skills. On the other hand, the criticism he has received also makes him feel uneasy. He wonders whether his life is valuable. Luo Tai'an
God doesn't want to repeat the master's life. In this case, wouldn't Lu Tai'an's beloved professor be in vain?
"What are you thinking about?" Cheng Zhen interrupted Luo Tian's thoughts and looked at the empty bowls and plates: "I'm glad you have such an appetite."
"Today's meal was so worthwhile. I learned a lot. Sure enough, you will be my most effective assistant." Luo Tian said with a smile: "Unfortunately, I am only a temporary nanny now. How about Xiaoya?"
Do we get along well?"
"It's a very strange feeling." Cheng Zhen didn't want to hide it in front of Luo Tian: "She looks mature and beautiful, but when she talks, she is very naive. This contrast makes me feel very weird. Can't she regain her mind?"
"I don't know. I heard it was caused by a car accident. I don't know if this is a mental illness. Maybe Xie Yun can help?" Luo Tiangang came up with this idea and immediately gave it up: "However, I can't make the decision.
You have to ask her brother."
"Who is her brother?"
Luo Tian was stunned: "I met him at the auction. He is my guest. He bought one of my paintings for a huge sum of money. We had some contacts later. I was also surprised. He actually entrusted his sister to me so confidently.
.”
"Don't you know that you are born with a trait that makes people trustworthy?" Cheng Zhen took away the bowls and chopsticks: "It's getting late, you should go to bed early."
"Thanks."
Luo Tian needs some time to digest everything he learned tonight. It seems that he needs to pay more attention to the knowledge of antique restoration.
