Sewing Will Have Stretchable Yarn To Remove Textiles.

< p > when sewing "a href=" //www.sjfzxm.com/news/index_p.asp > textile > /a ", people often encounter the following problems: for example, needle cutting or stretching through the stretch yarn (colloid or artificial colloid), so that it is easy to break the stretch yarn, and make the textile's scalability and the stability of the joints weaken.

Or the needle tip of the needle may have a stretch < a href= "//www.sjfzxm.com/news/index_c.asp > yarn > /a > forced fabric, or the friction between the needle and the stretchable yarn may drag the latter out of the textile and become a wire loop.

< p > in principle, sewing needles should be made of round needles.

However, it is very important not to use rough machine needles, because thick machine needles have more chances to have stretch yarn, and the friction between machine needles and stretch yarns increases. The use of 10# needles for rough round needles and special round needles is a multifaceted way. Using this kind of needle to sew stretchable textiles, more than half of them can be satisfied without worrying about additional remedial measures.

< p > round needles only move the yarn to one side rather than the needle tip needle may cut or penetrate the yarn (passing through the yarn). However, one thing to consider is that when the small needle is used to sew thick textiles, the strength of the needle is too low, which often results in too much deflection of the puncture fabric, resulting in a gap, resulting in needle jumping.

In this case, it is necessary to use the thicker machine needle to test the seam and find the suitable needle. It should not only have the least jumping needle, but also avoid the massive breakage of the fiber line.

< p > the more layers of stitched stretchable textiles, the higher the rate of loss. When the needle passes through the textile, the friction between layers will prevent the line from extending to the side.

< p > the greater the difference in sewing properties, the less difficult the a href= "//www.sjfzxm.com/news/index_f.asp" > sewing "/a" is. For example, the satin of the corset should avoid sewing with the stretchable textiles, because the former is very easy to break, and must use very small machine needles; and the needling needles with Coarse Round needles should be used for sewing the textile with stretchability.

If the two kinds of textiles are stitched together, the stitch on the top of the satin will be very irregular with the needle of the round needle, which is suitable for the stretchable textiles.

If you use a fine needle suitable for satin, the needle may be too deflected, which will lead to a sharp increase in the chance of jumping.

< p > however, the use of round needle needles to sew other common textiles (twill, silk satin) and stretchable textiles together will not produce undesirable results.

When sewing the fabric, the needle is introduced into the gap and the line is broken.

However, it needs to be pointed out that the seams that are sewn by needles of circular pointed machines are not regular than those of ordinary joints. This is because the round needle machine moves the wires aside.

< p > except for the rough round needles and special round needles recommended, the small round needles and the middle round needles can also be used because there are a wide variety of stretchable textiles, of which the four kinds of needle tips mentioned above are the most suitable ones and must be combined with practical choices.

< p > however, only the expansion line with envelopes is beneficial to the needle of the circular needle tip, so that the needle of the circular needle can slide along the fiber line.

If there is no wrapping line, there is a stretchable line. The round needle tip may press it out of the textile, or the friction between the wire and the machine needle may be very high, so that the former is dragged out to become a wire loop. In this case, the needle tip must be replaced by a very sharp tip, so that the needle can easily pass through the expansion line.

This must be taken into consideration when sewing thread tape or thin film on velvet fabric.

< p > in the market, there are often fashionable and stretchable textiles, some of which are man-made fibers.

Because it is easy to be affected by heat, there will be a doubling of difficulties in sewing such textiles.

When sewing this kind of textile, it is very important to use good quality needles. At the same time, we should also reduce the sewing speed and avoid the overheating of the needle.

< p > powdered powder on expanded textiles can reduce friction between needles and wires.

Similar results can be achieved by wetting textiles with water.

In this case, it is best to use rust inhibitor and soap to further reduce friction.

Applying dry soap before sewing can also reduce friction and reduce damage.
