All friends who love sewing, no matter novice or veteran, are always very interested in the ability of sewing machines to eat. After we contacted thousands of novices, we found that everyone's misunderstanding on this issue is widespread. So it is necessary to explain.
I will often tell novices this way, your sewing machine is not very thick.
The so-called sewing machine does not eat thick, is actually a forced conclusion based on the psychological gap of many novices. In fact, sewing machines are not so vulnerable. Troublesome things could have been avoided. The reason for emphasizing is that we have seen too many gaps between fantasy and reality, which has caused the machine to be annoying and annoying.
To explain briefly, eating thick is actually not what novices think, the soles of the shoes can be sewn through. If the normal two and three layers of denim are no problem, it is usually enough for home sewing. A thick sewing machine can reach 4 to 6 layers, and even 8 to 12 layers in extreme cases (this is a method that damages the machine and is not recommended). Based on past experience, novices often have naive fantasies, imagining that their sewing machine is as strong as a tank, and they can easily pass all tests, such as the junction of the jeans edge and the trouser seam folded to a thickness of seven or eight layers. Corners, such as thick and hard stitching when sewing bags, or patchwork that is sewn up and down. Novices who operate here often have problems such as repeated jamming, stranding, stagnation, broken needles and even thread jams leading to machine gear failures, and they are embarrassed and outraged. (In those cases, the correct operation method is to stop pedaling. Turn the handwheel to let the sewing machine slowly pass through hard, thick, uneven places, and then start sewing with a bicycle.)
[The concept of "eat thick"]
"Eat thick" contains two concepts, one is "eat hard" and the other is "thickness". Usually we use denim as a measure. In fact, we are talking about "eat hard", that is, the density of the fabric that can be sewn smoothly by the sewing machine.
The meaning of 4-layer denim is "same toughness as 4-layer denim." This thickness is generally a bit difficult to sew by hand. Machines with solid leather can pass through easily, and machines with meat spots can also pass, but it will accelerate wear. 4 layers of denim is also equal to the density of "1.5mm cowhide" or "3 layers of real fabric", or "8 layers of woolen". Now, everyone should understand the concept of eating thick that we usually talk about.
"Thickness" simply refers to the allowable height under the sewing machine's presser foot. We use soft woolen as an example. Stacked to a thickness of 8 mm, a good sewing machine can pass without jumpers. No matter how thick it is, it cannot be sewn because the needle cannot be penetrated to the end. If it is denim, 8mm, a 38-caliber pistol can pass through close shots perfectly. Don't think about hand sewing, and don't need to think about home sewing. . . Unless it is a binding machine or some industrial sewing machine.
Therefore, eating thick is related to the texture, thickness, and number of layers of the fabric processed by the sewing machine. It’s best to make a careful estimate first.
Simply put: soft fabrics can be thicker and can have many layers, such as woolen, cotton and linen, blends, etc. (but not more than 6mm, high-end machines 8mm); stiff fabrics, the number of layers should be less, and can't Too thick (such as canvas, real good, leather, denim, etc.) should not exceed 4 layers. Most machines have 2 or 3 layers. In one sentence, it is compactness. If you feel difficult to sew by hand, don't use a sewing machine to sew directly. (If unfortunately you happen to be a Popeye, just treat me as saying nothing)
When we recommend sewing machines to users, we usually talk about the concept of "eat hard" mentioned above, 2, 3, 4 layers of denim and so on. The data is conservative, based on the actual test does not damage the conventional situation of the sewing machine. Some businesses will introduce products very exaggeratedly, eating up to 8 or 16 layers of denim! This has caused a misleading to users, thinking that 8 to 16 layers of denim is a normal ability, and can be used to hold the soles of the shoes every day. It is not surprising that the results mentioned at the beginning have occurred.
What I want to say is that sewing machines can occasionally be tough, but it is not the norm. Just like when the adrenaline is soaring, the mother can lift a 1.8-ton car in order to rescue the child who was crushed in the carriage. This is not impossible. Weightlifters can lift more than 4 times their own weight, but they cannot do this every day. This is why the data we provide looks conservative. I don’t want to say that the XX machine can sew 12 layers of denim, although it has been sewn for a while, which makes me understand that its design margin is very sufficient, but I will not claim that they can be used in this way, because it does not It is meaningless, it can only add trouble to everyone in vain, and wait until the machine is scrapped early, that is the real trouble.
Now, do you have a more perceptual understanding of the concept of sewing machine eating thick? If you still have any questions, please leave a message for questions.
If you understand that eating thick is a balanced concept, you won't let your love machine do things that can only be achieved by soaring adrenaline.
