Understanding Needle Types
Needles are a critical component in sewing machines, affecting the quality and efficiency of stitching. The right needle helps in achieving clean stitches, reduces damage to the fabric, and increases the life of both the needle and machine. Each needle type is designated for specific purposes, based on their size, shape, and design.
135×17 Needle Specifications
The 135×17 needle type features a rounded point (also known as a ballpoint) which gives it the ability to penetrate fabrics without causing damage. This is especially important when working with more delicate materials.
Applications of 135×17 Needles
The 135×17 needle is commonly used in operations involving:
- Woven Fabrics: Such as cotton and polyester blends.
- Knit Fabrics: Ideal for sewing stretchy materials.
- Denim and Heavy Fabrics: Suitable for thicker materials requiring robust stitching.
Choosing the Right Needle Size
Selecting the appropriate needle size is vital for achieving optimal performance with the DDL 8700. Needle sizes for the 135×17 type generally range from:
- Size 9 (60/8): For very fine fabrics.
- Size 11 (75/11): For light to medium-weight fabrics.
- Size 14 (90/14): For medium-weight fabrics such as denim.
- Size 16 (100/16): For heavier fabrics.
Choosing a needle that matches the weight of the fabric being used can enhance stitch quality and prevent fabric damage.
Benefits of Proper Needle Selection
Using the correct needle type and size with the DDL 8700 offers several advantages:
- Improved Stitch Quality: Ensures consistent tension and uniform stitches.
- Minimized Fabric Damage: Reduces the risk of snagging or piercing issues.
- Enhanced Performance: Reduces thread breakage and allows for higher sewing speeds.
Understanding and applying these principles can lead to superior sewing outcomes, increased productivity, and less frustration.
Maintenance Tips for Needle and Machine
Maintaining the DDL 8700 sewing machine and its needles is essential for longevity and performance. Here are several maintenance tips:
- Regular Needle Replacement: Change needles after every project or at least every 8-10 hours of sewing.
- Cleaning the Machine: Keep the area around the needle and the feed dogs clean to prevent fabric snags.
- Oiling: Regularly oil your machine per the manufacturer’s instructions to ensure smooth operation.
Common Problems and Solutions
Skipped Stitches
If you experience skipped stitches, ensure that you are using the correct needle and that it is installed properly. A damaged or dull needle can also cause this issue.
Needle Breakage
Needle breakage often results from using the incorrect needle size for the fabric. Check for burrs on the needle plate or the feed dogs that may cause friction.
Puckering Fabric
Puckering can occur if the needle is too large or if the fabric tension is set too high. Adjust tension settings and use a needle suited for the fabric type.
