When sewing stretchable textiles, people often encounter the following problems: for example, needle cutting or through a stretchable yarn (colloidal or artificial rubber), which makes it easy to break the stretchable yarn. It reduces the stretchability of the textile and the stability of the seam. Or the needle tip may force the stretchable yarn away from the textile, or the friction between the needle and the stretchable yarn, which may pull the latter out of the textile and become a loop.
Stretchable textile
In principle, for sewing textiles that have stretchability, a needle with a round needle should be used. However, it is important not to use a thick needle, because the thick needle has more chances of touching the stretchable yarn, and the friction between the needle and the stretchable yarn is increased, the round needle tip and the special The use of round needle tip 10# needles is multi-faceted. These needles are used to sew stretchable textiles, more than half of them, and you don't have to worry about taking additional remedies to get satisfactory results.
The round tip only moves the yarn to one side, unlike a sharp needle that can cut or penetrate the yarn (passing through the yarn), but one thing to consider is when using a small needle to sew thick textiles. Due to the low strength of the needle, the deflection of the puncture textile is often too large, and a void is formed, which causes a jump stitch. In this case, it is necessary to use a thicker needle to test the seam and find a suitable needle. It must not only have the least jump stitch, but also avoid a large number of fiber strands.
The more the number of layers of the stretchable textile, the higher the rate of breakage. When the needle passes through the textile, the friction between the layers prevents the line from extending to the side.
The more difficult the sewing properties are, the more difficult the sewing work is. For example, the satin of the corset should be avoided from sewing with the stretchable textile. Because the former is easily broken, it is necessary to use a very fine needle. For sewing textiles that have stretchability, a needle with a rounded needle tip is required. If you sew these two kinds of textiles together, using a round needle needle for textiles with stretchability, the seams on the satin will be very irregular. If a fine needle suitable for satin is used, the needle may be skewed too much, which will greatly increase the chance of jumping.
However, the use of round needle needles to sew other common textiles (twill, satin) and stretchable textiles together does not have undesirable effects. Because of the sewing of such fabrics, the needle is introduced between the line gaps, and the breakage of the thread is also avoided. However, it should be pointed out here that the seams sewn by the round needles are not neat than the ordinary seams, because the round needles move the thread away from one side.
In addition to the recommended thick round tip and special round tip, slight round and medium round tips can also be used, as there are a wide variety of stretchable textiles, of which the four tip shapes described above are the most suitable. Must be combined with the actual choice.
However, only the flexible wire with the covered wire is beneficial to the needle of the round needle, so that the needle of the round needle can slide along the fiber line. There is a stretchable wire without a covered wire. The round needle tip may push it out of the textile, or the friction between the wire and the needle may be high, causing the former to be pulled out and become a wire loop. In this case, it must be used. A very sharp tip replaces the round tip so that the needle can easily pass through the stretchable line. Be sure to consider this when sewing a tape (cord) or thin film on a velvet.
In the market, there are often fashionable and flexible textiles, some of which are man-made fibers. Because it is susceptible to heat, it can be cumbersome when sewing such textiles. When sewing such textiles, it is very important to use a good quality needle, while reducing the sewing speed and avoiding overheating of the needle.
Powdering on expanded, stretchable textiles reduces friction between the needle and the thread. A similar effect can be obtained by using water to wet the textile. In this case, it is best to use a rust inhibitor, plus soap to further reduce friction. Applying dry soap before sewing can also reduce friction and reduce damage. (Chinese brand clothing network)
