How To Sew Stretchable Textiles With Equipment

In sewing

In textiles, people often encounter the following problems:

(1) when the needle is cut or penetrated by a stretchable yarn (colloid or artificial gum), it is easy to break the stretch yarn, which makes the textile's stretching performance and the stability of the joint weaken.

(2) needle needles may be removed from the textile with stretchable yarns.

Or because of the friction between the needle and the stretchable yarns, the yarn is dragged out of the textile to form a wire loop.

In principle, sewing needles should be made of round needles.

Coarse machine needles can not be used because thick machine needles have more chances to encounter stretchable yarns, thus increasing friction between machine needles and stretchable yarns.

However, if the 10# needle is used for rough round needles and special round needles, satisfactory results can be obtained without additional consideration of additional remedial measures.

The round needle tip only moves the yarn to one side, rather than the needle tip needle may cut or pass through 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, often causing the puncture fabric to be too deflected, resulting in a gap, resulting in the 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.

The more layers of stretchable textiles, the higher the ratio of sewing loss.

When the needle passes through the textile, friction between layers will prevent the line from spreading to the side.

The greater the difference in properties, the more difficult the sewing work is. For example, the satin of the corset should avoid sewing with the stretchable textiles, because the former is very easy to break, and the machine must be very small.

If the two kinds of textiles are stitched together, such as the use of round needle needles suitable for stretchable textiles, the seams on the satin will be very irregular. If the suitable needle is suitable for the satin, the needle may be too deflected and the chance of jumping is increased.

However, sewing needles with other ordinary textiles (twill, satin) and stretchable textiles will not be undesirable.

Because sewing needles are introduced into the gap, and the line breaks are avoided.

It needs to be pointed out that the joints sewn by the needle of the circular pointed machine do not have regular seams. This is because the round needle machine moves the line to the side.

In addition to the recommended rough tips and special round needles, the small round needles and the middle round needles can also be used because there are a wide variety of stretchable textiles, and the most suitable form of needle tips must be combined with practical choices.

Only using a telescopic line with envelopes is conducive to sewing needles of circular needles, so that needle needles will slide along the fiber line.

Using a telescopic line without a wrapping line, the round needle tip may press it out of the textile, or increase the friction between the wire and the machine needle, causing the thread to be dragged out to become a wire loop. In this case, the needle tip must be replaced by a very sharp tip to make the needle easier to traverse through the expansion line.

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

Expansive

Powdering powder can reduce friction between needle and thread.

Similar results can be achieved by wetting textiles with water.

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

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

Spraying a layer of plastic fog around the joints is also a way to reduce damage.
