Sewing machines are closely related to our lives. The clothes we wear in our daily life are all related to sewing machines. Even many people have sewing machines at home as their daily hobby to make clothes. We need to know the needle type comparison table of sewing machine?

Sewing machine needle model comparison table?

1, sewing needle model: According to statistics, there are thousands of sewing needle models produced in countries all over the world, and each sewing needle has several or several needle numbers and dozens of needle tip shapes. At present, there are three commonly used methods to express the number of sewing needles: counting system, metric system and British system.

Numbering system-Numbers are used to indicate the thickness of the needle bar, and the numbers themselves have no special significance. The smaller the number, the thinner the needle. Knitwear sewing usually uses 6- 16 stitches. China needle, Japanese? Organ? The needles are numbered.

Metric-Starting from 50, the number of stitches increases in units of 5 until 380. The number of needles multiplied by 0.0 1 is the actual diameter of the needle bar (mm). The number of stitches commonly used in knitting production is 55- 100. This kind of needle count is widely used in Germany and is gradually used in China at present.

English system-represented by 3 digits, such as 022,025,027,040. The number of needles multiplied by 0.00 1 is the actual diameter (inch) of the needle bar. In people? The company (union) adopts this pin number.

2. New sewing needle: With the increase of sewing equipment speed, the needle will have fierce friction with sewing materials, thus causing the needle to heat up. The surface temperature of needles can reach above 200℃, which is very dangerous to chemical fiber stitches or fabrics. At such a high temperature, the yarn may melt. Therefore, some high-speed sewing machines use needle cooling mechanism to reduce the surface temperature of needles. At the same time, something suitable for this environment has been developed? High speed needle? And then what? Double needle? .

The needle bar of a double-section needle is divided into two sections, the upper section is thick and the lower section is thin, the upper section can reduce the vibration of the needle, and the lower section can reduce the friction between the needle and the sewing material, thus reducing the surface temperature of the needle.

The high-speed machine needle, except that the needle bar is similar to a double-section needle, protrudes on both sides of the needle hole of the needle part, and is 5%-7% thicker than the needle bar part. When the needle tip pierces the sewing material, the sewing material yarn is pushed away, which is also to reduce the friction between the needle bar and the sewing material and reduce the surface temperature of the needle.

How to clean and maintain sewing machines?

First, the sewing machine cleaning method

1. Cleaning of cloth feeding teeth: Remove the screw between the needle plate and the cloth feeding teeth, remove cloth wool and dust, and add a small amount of sewing machine oil.

2. Remove dirt and add a small amount of sewing machine oil.

3. Cleaning of other parts: All parts of the sewing machine surface and panel should be cleaned frequently and kept clean.

Second, the maintenance method of sewing machine

Refueling position: each oil hole on the machine head lubricates the upper shaft and the parts connected with the upper shaft; Components in the panel and movable components connected with each component; Lubricate the presser foot bar, needle bar and their connecting parts; Clean the moving parts at the lower part of the machine board and add less oil.

Special sewing machine oil must be used. The sewing machine should be fully oiled after continuous use for one or several days. If you refuel between uses, the machine should idle for one turn, so that the oil can be fully saturated and the excess oil can be thrown out, and then the machine head and table top should be wiped clean with a clean soft cloth to avoid staining sewing materials. Then thread to sew the rag, wipe it with the action of sewing thread, and throw out excess oil stains until there are no oil stains on the rag, and then formally sew it.

Pay attention to your health

1. After the work is completed, insert the needle into the pinhole plate, lift the presser foot, and cover the machine head with a hood to prevent dust from invading.

2. When starting work, first check the main parts, how heavy it is to step on it, whether there is any special sound, whether the pointer is normal, and so on. If abnormal phenomena are found, they should be repaired in time.

The machine has been used for a long time and should be overhauled. If the worn parts are found, they should be replaced with new ones.

4. After the work is completed, insert the needle into the pinhole plate, lift the presser foot, and cover the nose with a hood to prevent dust from invading.

The above sewing machine needle model comparison table? How to clean and maintain sewing machines? That's all. I hope the above introduction can help you in the use of sewing machines. Sewing machines are closely related to our lives. Without it, our life will lose a lot of fun. Without it, we can't wear beautiful clothes and some puppet toys It is necessary to know.
