Since the sewing thread works at a high speed, good sewing thread oil must have three conditions: 1: excellent lubrication, 2: excellent thermal conductivity; 3 excellent electrical conductivity.
I collect information on some silicone products summarized by experience for your reference.
Lubricating (oiling) the sewing thread is an important process.
Choosing a good lubricant has a great impact on the lubricity of the sewing thread. For now, silicone wax-based lubricants are the most lubricating agents on the market. There are two types of oiling for sewing threads, one is the dipping method and the other is the contact method. Lubricant package available under dipping method
Including the following two: cationic hydroxy silicone oil emulsion (male milk) and silicone wax water emulsion. Under the contact method, there are three types of lubricating oils that can be selected: thread-forming silicone oil (line oil), 201 methyl silicone oil, and (anhydrous) silicone wax emulsion. The performance of the products listed above is from low to high. Of course, there are differences in production from different manufacturers. For example, for the silicone wax water emulsion under the dipping method, if it is done well, it can be completely adsorbed to the sewing thread, and only water is left in the end, without pollution, and it is easy to clean. There is also 201 methyl silicone oil under contact method.
Silicone wax for thread sewing. In principle, silicone wax can stay on the surface of sewing threads for a longer time. The structure of the sewing thread is fluffy. After oiling the sewing thread, the oil easily penetrates into the inside of the thread. If the oil goes into the inside of the thread, the sewing thread will increase toughness and tension. The line manufacturer guarantees the lubrication performance of the line by increasing the oiling rate. Not only can it provide good lubricity, but also other properties of the sewing thread can be greatly improved!
The sewing thread is always used on the sewing machine. The speed of sewing threads is getting faster and faster. It is generally around 5000 stitches / minute in China, and around 7000-8000 stitches / minute in foreign countries. It can reach 9000 stitches / minute faster. At this speed, you can infer how high the temperature of the sewing machine needle is!
Silicone wax has the following advantages:
(1) Provide good lubricity, which can make the sewing machine speed up to more than 7000 stitches / minute;
(2) Good anti-static property, providing the bunching property of sewing thread, that is, the thread is not easily dispersed. Because the wire is not one, it is twisted together. If the static electricity is large, the wires will be separated;
(3) The difference between dynamic / static friction is small. In this way, the jitter of the sewing machine needle during the upward and downward movement is small. The stitches are flat when punched out, which improves the sewing quality;
(4) Reduce oiling rate and production cost;
At present, many domestic manufacturers can produce silicone wax emulsions that are fined by dipping. The difference between *** is the high quality, as mentioned above, can it be absorbed cleanly, can it be recycled under a two-way pump, it needs heating, etc. The (anhydrous) silicone wax emulsion under contact method,
Silicone wax is a special synthetic silicon wax developed for sewing and embroidery threads. In addition to the properties of ordinary 201 silicone oil, it has better thermal effects, low head breakage, low wool, and good antistatic properties. Low oiling rate, generally equivalent to 1/3 of 201 silicone oil; and can greatly improve the smoothness and softness of the thread, increase the gloss of the thread, and have excellent antistatic properties.
Features and characteristics:
1. Silicone wax has excellent lubricity. The sewing thread treated with it will only generate a slight peak tension when passing through the thread guide and the tensioner, making the surface of the yarn smooth and soft. , Abrasion resistance, less color change, can not afford to ball.
2. Silicone wax has good thermal stability and has thermal screen protection for the yarn.
3. The yarn is endowed with excellent thermal protection and antistatic properties.
4. The abrasion of the tension device on the needle and its sewing machine is small.
5. There will be no oil leakage. Silicon wax products have been widely recognized by users in terms of giving yarn smoothness, bunching, antistatic, reducing hair and broken ends.
