Power Net
Power Net is a fine mesh warp-knit textile made mainly from nylon and polyurethane, with high stretch and moderate compression and shaping support.
Definition and Overview
Power net is a thin mesh knit that uses polyurethane elasticity to stretch along the body while retaining recovery force. It is often made as a warp knit, and its strength and stretchability vary depending on the mesh size, yarn thickness, and how polyurethane is used.
“Power” does not simply mean that it stretches; it refers to holding power and compression when stretched. However, there is no unified standard for the degree of holding power, so even materials called power net vary in texture and tightness.
Features
Its basic appearance is thin and sheer, but fabrics with a high knitting density can reduce how much skin shows through. The surface is relatively smooth, and while it is lightweight and breathable, coarse mesh and yarn usage may make it easy to snag.
Many types stretch in both the lengthwise and widthwise directions, but the stretch rate and recovery differ by direction. For applications that support the body, it is important to check not only stretch but also recovery after repeated stretching, feel against the skin, and sheerness.
- Fits the body flexibly and easily
- Can provide a moderate hold even in a thin material
- The mesh structure can help reduce stuffiness
- Needles, hook and loop, and similar items may catch in the mesh
Main Applications
It is used in areas that require fit and support, such as shapewear, lingerie, the side and back of bras, and girdles. In swimwear, sportswear, and dance costumes, it may also be used as lining, panel inserts, or a layered material.
Because it is thin and makes it easy to take advantage of breathability, it is also suitable for spring and summer innerwear and costumes. However, since it is not a material for insulation, in autumn and winter products it is generally used as an inner shaping layer or as a layer with other textiles.
Selection and Handling Notes
Depending on the application, check the stretch direction, holding power, thickness, mesh fineness, and sheerness by actually stretching the material. Select it by organizing the required performance for each use area, such as prioritizing appearance for outer fabric and skin feel and recovery for lining and shaping sections.
When cutting, arrange the grain so the textile is not stretched. During sewing, consider adjusting the differential feed and using a stretch-compatible stitch to avoid waviness caused by overfeeding. The seam also needs a specification that can follow the stretch of the textile.
If polyurethane is damaged by washing or heat, stretch and recovery may decline. Shrinkage and dimensional change vary depending on blend ratio, knit structure, and finishing, so before mass production, perform wash tests and sewing tests, and confirm the care label that is suitable for the product.
Differences from Similar Terms
Mesh refers broadly to textiles with an open, net-like structure and does not require holding power. By contrast, power net generally refers to a net-like knit that emphasizes stretch and body support.
Tulle is also a sheer, net-like textile, but many types focus on decorative qualities and a light appearance, and they usually are not intended to provide the holding power needed for shaping. Tricot is a type of warp knit, and power net may be made from warp-knit structures including tricot.
Frequently Asked Questions
How much does power net stretch?
The stretch rate varies greatly depending on the knit structure, yarn thickness, polyurethane blend ratio, and arrangement. It may also stretch differently in the lengthwise and widthwise directions. Rather than relying only on numbers, check the actual material to confirm that it stretches in the needed direction and recovers sufficiently after release.
Can power net be machine washed at home?
Some types can be machine washed at home, but this depends on the material composition, processing, and product specifications. Strong friction, heat, and chlorine bleach can all cause deterioration. Follow the care label, and before production, check the dimensions and recovery after washing.
How can waviness in power net seams be prevented?
Sew without pulling the textile, and adjust presser foot pressure and differential feed with test stitching. Match the sewing thread, needle, and stitch type to the stretch of the textile. After sewing, it is important to stretch the seam and check that there is no thread breakage or seam failure.
