Introduction
Leno weaving is an advanced textile technique designed to create stable, slip-resistant fabrics by twisting warp threads around the weft. One of the most critical components of this system is the leno device heald, which guides and controls warp thread movement during weaving. With various designs available, selecting the right heald type is essential for achieving optimal weaving performance. Among the widely used healds is the 33/J Leno Heald, known for its precision and durability.
This article explores the types, differences, and shapes of leno device healds, helping manufacturers select the best option for their production needs.
What Are Leno Device Healds?
Leno device healds are specialized metal or synthetic loops with an eyelet that holds and controls warp threads. Unlike traditional healds that lift or lower warp threads, leno healds twist two warp threads together before inserting the weft, forming a stronger and more stable weave.
Types of Leno Device Healds
1. Standard Leno Healds
- Designed for basic leno weaving applications where simple twisting of warp threads is required.
- Made of stainless steel or high-strength synthetic materials.
- Best for lightweight fabrics like netting and fine mesh textiles.
2. Twisted Wire Leno Healds
- Feature a curved or twisted structure to enhance the twisting motion of warp threads.
- Provide greater stability and precision, reducing yarn displacement.
- Commonly used for medium-weight fabrics and industrial textiles.
3. Flat Leno Healds
- Designed with a flat body and smooth eyelet, ensuring less friction and wear on warp threads.
- Ideal for delicate fabrics where minimizing thread damage is crucial.
- Often used in the production of high-end curtains, sheers, and decorative textiles.
4. Open-Eye Leno Healds
- Have a wide-open eyelet that allows for easier threading and smoother movement of warp yarns.
- Recommended for heavy-duty weaving, such as technical fabrics and reinforcement textiles.
- Reduces tension buildup, preventing breakage in thick or stiff yarns.
5. 33/J Leno Healds
- One of the most widely used leno healds in modern weaving.
- Offers high precision and durability, making it ideal for fine and intricate weaving applications.
- Designed to withstand high-speed weaving, ensuring smooth operation and minimal thread breakage.
- Commonly used in curtain manufacturing, net fabrics, and high-end decorative textiles.
Differences Between Leno Healds
Each leno heald type serves different fabric needs and varies based on:
✅ Material: Some are made of stainless steel for durability, while others use plastic or composite materials for lightweight applications.
✅ Eyelet Design: Some have closed eyelets for firm grip, while others have open eyelets for easier threading and higher flexibility.
✅ Twisting Capability: Some healds provide stronger twists for rigid fabrics, while others allow gentle movement for delicate materials.
✅ Compatibility: Different healds are suited for specific leno devices and weaving machines, such as Dobby Staubli and Jacquard systems.
Shapes of Leno Healds
The shape of a leno heald influences how efficiently it guides warp threads and ensures smooth weaving. Here are the most common shapes:
1. Straight Leno Healds
- Simple design with a linear structure.
- Best for standard leno weaving where minimal movement control is required.
2. Curved Leno Healds
- Have a slight bend to assist in warp thread twisting.
- Improve fabric consistency and reduce thread breakage.
3. Loop-End Leno Healds
- Feature rounded ends to allow for smooth movement of the warp threads.
- Prevents yarn friction and damage, making them suitable for delicate textiles.
4. Double-Twist Leno Healds
- Designed for maximum twisting effect, ensuring tight and strong fabric structures.
- Common in heavy-duty weaving applications, such as industrial textiles and reinforced fabrics.
Conclusion
Selecting the right leno device heald depends on the fabric type, machine compatibility, and production requirements. The 33/J Leno Heald, in particular, is a reliable choice for achieving high-quality, precision weaving. Whether you need flat healds for delicate fabrics, twisted wire healds for extra stability, or open-eye healds for heavy-duty textiles, choosing the right design can enhance productivity, fabric quality, and weaving efficiency.
