As a quick and easy way to produce garments, automatic sewing machine are becoming more popular. They are easy to maintain, so you can concentrate on the actual creation of your garment and not worry about how it works. Nevertheless, they can be expensive, and there are important considerations when choosing one.
Mechanical vs computerized machines
The differences between a mechanical sewing machine and a computerized sewing machine may seem confusing to newbies, but it doesn’t have to be. Each machine has its pros and cons. Consider the features you are looking for and the type of project that you will be sewing before you buy a sewing machine.
Computerized sewing machines and embroidery machines computerized can be more costly than their mechanical counterparts. They have more features and capabilities. They are also much easier to use. A computerized model is a good option for beginners and experienced sewists.
A computerized sewing machine allows you to adjust your stitch settings. It may even include automatic buttonholing and thread cutting abilities. These are great features for someone who plans to sew a lot of fabric or embroidery.
Although a computerized sewing machine can be a huge improvement over a manual one it can also be overwhelming. You’ll want to be sure you don’t pay for features you won’t actually use. This is especially important if you are on a budget.
Unlike a computerized sewing machine, a mechanical sewing machine doesn’t require the user to set up stitches. Instead, a series of gears turns an oscillating needle. Mechanical machines are simpler and easier to use.
A good quality sewing machine will do a great job and is much cheaper than its computerized counterparts. However, they aren’t able to do everything that a computerized machine can.
The technology is not the main difference between a computerized and a mechanical sewing machine. Both types can perform straight stitches, but computerized machines are capable of performing zigzags or other decorative stitches.
Computerized machines are the best option for large projects and people who love complex designs. As a result, they can be expensive, but they’ll also last you for a long time.
On the other hand, a mechanical sewing machine can be more affordable, and they’re a great option for beginners and those with limited budgets. Besides, they don’t have the bells and whistles that a computerized machine will have, so they’re easy to use.
With increasing fabric thickness, the stitch length decreases linearly.
We have studied the effects of presser height on the sewing machine’s stitch length and density. Optimal presser height is derived based on experimental results. To ensure a balanced stitch pattern, it is important to determine the best presser height for fabrics.
To examine the effect of sewing machine parameters, different stitches were sewn on each fabric. Fabrics were tested at four different stitch densities. These included lockstitch, chain, three-thread overedge and four-thread overedge. Sewing speed was a factor in influencing the pattern of the stitch. Lockstitch was the most affected by the amount of thread used. However, the effect of thread consumption was moderated by presser height.
The zigzag stitch showed a proportional increase in width with increasing presser height. The lock stitch had the fastest stitch speed at 200 RPM. This resulted in a uniform stitch pattern and a balanced seam allowance.
Zigzag stitches also showed high seam strength under a wide stitch width. This is a consequence of the internal frictions of fabric. As the presser height increased, the density of the stitch increased.
For a more accurate analysis, the sewn patterns were evaluated using a sewing parameter measurement device. An automatic sewing process was designed for garment production. Each fabric was tested at different thicknesses. They were all 100% cotton with different fiber compositions.
The ISO 5084: 1996 standard measured the fabric thickness and recorded it. After 24 hours of conditioning, the thickness of the fabric was measured again. To compare the appearance of the sewn garment with different textile properties, statistical analysis was done on the sewing parameters.
Optimal presser height for each fabric sample was derived from the experimental results. Stitch length, thickness, and the amount of sewing threads consumed were also measured. A regression equation was created to determine the stitchability of the pattern. A stitch pattern can have a positive or a negative effect on the stitch’s sewability depending on the sewing conditions.
Besides the physical characteristics of the fabrics, the weight and the SPI values of the fabrics were also measured. Results from the study showed that the SPI values were correlated with most of the variables.
Easier to maintain than basic sewing machine
Learning how to sew can be a great way to expand your skills. Although it sounds simple, it is not easy. It takes patience and practice to master the art. It is also important to maintain your sewing machine’s smooth operation.
You can prevent a lot of costly repairs by keeping your sewing machine clean. A few minutes of cleaning each day will make your machine last longer.
One of the most important things to remember is to use the same thread on your machine. The wrong thread can make your stitches messy or even break your needle. Make sure you use the right kind of thread to avoid these problems.
The needle must also be replaced as part of your maintenance plan. After four hours of sewing, you should replace the needle.
Your machine should also be oiled. Using too much oil can damage parts of your machine. A small amount of light, refined oil will help your machine function properly.
Most sewing machines come with an automatic needle-threader. However, it’s important to follow the manufacturer’s instructions and check the manual before using this feature.
Before you start your sewing project, you’ll need to set up your machine. If you’re a beginner, you can buy a model with a speed control button. This will help you get started with a smooth pedal.
A good way to do this is to practice your stitches on a piece of printed paper. You can also print free patterns from online stores. These patterns are a great way for you to try out your new sewing machine.
Your machine will run smoothly if it is free from fur and dust. Use a soft brush to clean the throat plate on your sewing machine.
You can repair any mechanical problems that may occur with your machine, in addition to keeping it in top condition. Rethreading is a good option if your stitching is uneven or tearing.
If you’re experiencing a sewing machine malfunction, you may need to call a technician. An expert can tell you what you need to do and can even check your machine to make sure it’s working properly.
Automatic sewing machine does not allow for thin fabrics
An automatic sewing machine is a machine that performs the sewing process automatically. It is an important step in garment manufacturing. However, the current automated sewing technology can only sew rigid materials like cotton. This is why research is necessary to expand the technology to other fabrics.
Different types of fabrics were tested to determine their appearance and sewing ability. They included silk, mesh fabric, cotton-PET blend fabric, and others. These fabrics were commercially available. They were then measured for their thickness, fiber composition, and weight. Table 1 shows the physical characteristics of these fabrics.
Also, the mechanical properties of the fabrics were determined. A regression equation was obtained for the sewability of these fabrics under different sewing conditions. The correlation between sewing conditions and textile properties, such as seam strength, stitch length, lock stitch pattern, and stitch length, was shown. This was moderated multiple regression analysis.
For this study, 12 different types of fabrics were selected. The thickness of the fabrics was determined using ISO 5084:1996). Fabrics with thinness less than 0.5 mm were excluded from the study because stitches could not be formed properly when the fabrics were moved by the automatic feeding system. Afterwards, the fabrics were fixed with a template.
Using a computer numerical control sewing method, two-dimensional seams were produced. The seam allowance was a key factor in determining the overall seam strength. The overall seam strength increased if the stitch width was large. The seam strength decreases when the stitch width is narrow.
Based on the results, a pattern was created. Two types of stitches were performed on the fabrics: zigzag and lock stitches. The seam strength of zigzag stitches was high despite having a large stitch width. Similarly, lock stitches had a balanced stitch and seam allowance.
Depending on the fabrics and sewing conditions, the best presser height was determined. The fabric’s thickness and roughness correlated strongly with the presser height. Similarly, friction force and sewing speed played a significant role in stitch formation. As presser height increases, the density of the stitch increases. It was therefore recommended that thicker, heavier and smoother surfaces have a higher pressing height.
