Sewing Needle
A sewing needle is a slender needle with an eye for threading thread and a point for passing through fabric, used to join fabric and accessories by hand.
Definition and Overview
A sewing needle is a hand-sewing tool used to thread thread through the eye of the needle and repeatedly pass it through fabric to form stitches. It is used for processes and finishing details that are difficult to handle with a sewing machine, such as basting, button attachment, blind hemming, and repairs.
In general, sewing needles differ in length, thickness, point shape, and eye size. Choosing one according to the thickness of the textile, the density of the weave or knit, the thread used, and the sewing method makes it easier to achieve smooth stitching and a clean finish.
How to Use
Use thread that is thin enough to pass through the needle eye without force, and avoid taking more length than necessary. Advancing the needle at the proper angle to the fabric and keeping the stitch length and spacing even helps produce stable stitching.
When sewing thick materials or pushing the needle through, use a thimble. Forcing the needle and bending it may cause breakage, injury, or damage to the textile, so if it is difficult to pass through, review the type and thickness of the needle.
- For basting, choose a needle that is easy to handle and less likely to damage the textile.
- For button attachment, check the thickness and eye size to match the buttonhole and thread thickness.
- For blind hemming, a thinner needle is used so that the stitches do not show on the outer fabric.
Types and Selection
Sewing needles include versatile general-purpose needles, short fine needles suited to small, precise stitches, and longer needles that are easy to use for basting. Since the way names and sizes are indicated may differ by manufacturer and market classification, check the length, thickness, and intended use as well.
For thin fabrics and tightly woven cloth, a fine needle with a sharp point is suitable. For thick materials, layered seam allowances, or button attachment, consider strength and eye size. However, a needle that is too thick may leave holes in thin fabric or cause the thread to pucker.
For knits and stretchy textiles, a needle with a point shape that is less likely to cut the loops may be selected. It is important to do a test stitch in an inconspicuous area and check for holes, puckering, or skipped stitches.
Care and Safety Precautions
Do not use needles with dulled points, bent needles, or needles with visible rust. Poor surface condition can cause snagging on the textile or damage the thread. After use, keep them away from moisture and store them in a pincushion or box.
Do not leave needles on the fabric or worktable during work; return them to a designated place such as a pincushion. After sewing, check the number of needles, and if one breaks, collect the fragments. In workplaces where preventing contamination in products is necessary, follow management procedures including needle inspection.
Differences from Similar Terms
A straight pin is a needle used to temporarily secure fabric before cutting or sewing, and is not usually used for stitching with thread. A sewing needle differs in that thread is passed through the eye to form stitches.
A machine needle is a needle attached to and used with a sewing machine, and its shaft and eye position, as well as the way thread is moved, differ from a hand sewing needle. Use a sewing needle for hand sewing, and choose the appropriate needle for the fabric and thread when machine sewing.
Frequently Asked Questions
What should I do if needle holes are noticeable when hand sewing thin fabric?
The needle may be too thick for the textile. Consider a thinner needle and thinner thread that blends with the textile, and avoid making the stitches too tight. Before the actual work, do a test stitch on the same fabric and check for needle holes or puckering.
Can a sewing needle and a machine needle be used as substitutes for each other?
As a rule, no. A machine needle has a shape suited to the mechanism of the sewing machine, and its structure differs from a sewing needle intended to be handled by hand. Use a sewing needle for hand sewing, and choose a machine needle suitable for the fabric and thread for machine sewing.
