Computer pattern maintenance and needle selection


First, the maintenance of computer pattern machine

(1). It is the cleaning of the shuttle bed. The shuttle bed is the core of the computer sewing machine work, and it is also the most prone to faults. Therefore, it is necessary to frequently remove the dirt from the computer pattern machine and add a small amount of sewing machine oil;

(2). To clean the feed dog, remove the screw between the needle plate and the feed dog, remove the cloth and dust, and add a small amount of special oil for the sewing machine;

(3). It is the cleaning of other parts, that is, the surface of the computer sewing machine and all parts in the panel should be cleaned up. We have a special few minutes after the operation is to clean the computer sewing machine, which will create a good working environment for the future work and the dual purpose of maintaining the machine!


Second, the needle

The needles used in computer vehicles are classified according to their functions, such as needles for straw hats, needles for seaming machines, needles for sewing leather, and needles for sewing clothes that we commonly use. The main point here is the needle for household sewing machines. When buying a new sewing machine, it is often accompanied by a 14- or 16-pin needle with a pair of eccentric rods. The thickness and type of the needle are most suitable for sewing cotton textiles because the needle tip of the needle is sharp. Shaped, after being woven into the textile, the warp and weft yarns can be separated and the warp and weft yarns of the fabric can be kept from being damaged. The needles are divided into different specifications such as No. 9, No. 11, No. 14, No. 16, and No. 18.
Because the clothes we usually sew are not exactly the same, they are hard, soft, thick, and thin. Therefore, different sizes of needles and different models are required. When sewing a thick and hard cloth, use a thicker needle, that is, a larger number. The number is the size of the needle. The larger the number of each bag, the thicker the needle. The smaller the number of the needle, the thinner the needle. The 18th needle is thicker than the 16th needle, while the 16th is thicker than the 11th needle. The needle is suitable for the thickness, thickness, softness and hardness of the sewing material.
