Stainless Steel Hollow Embroidery Needle TP304 TP316L Capillary Tube

A capillary tube works on the principle of capillary action, where liquid can flow through narrow spaces without the assistance of external forces (like gravity). This is primarily due to surface tension, adhesive and cohesive forces.

Hollow Embroidery Needles: Types and Applications

Hollow embroidery needles (also known as tubular embroidery needles or cord embroidery needles) are specialized needles designed for embroidering with thick or three-dimensional materials such as ribbons, cords, ropes, and threads. Their defining feature is a hollow shaft that allows bulky materials to pass through the needle tube, minimizing friction.

Key Features of Hollow Embroidery Needles

1. Hollow Shaft: The needle’s tubular design allows threads or ribbons to pass through the tube instead of a traditional eye, reducing wear on delicate materials.

2. Needle Tip: Typically rounded or slightly pointed to avoid piercing fabric fibers, ideal for surface-level embroidery.

3. Compatible Materials: Ribbons, cords, yarns, metallic threads, and other bulky or textured materials.

Standard Hollow Embroidery Needle

• Features: Small tube diameter (1–2 mm), rounded tip, short shaft.
• Applications:
• Narrow ribbons (2–4 mm) for floral designs (e.g., roses, leaves).
• Fine yarn or cord embroidery for filling large areas.

Selection Guide

1. By Material Thickness:

- Thin ribbons (1–3 mm) → Standard hollow needle (1–2 mm bore).

- Thick cords (5+ mm) → Large-bore needle (3–5 mm).

2. By Complexity:

- Simple flat designs → Standard needle.

- Multi-layered 3D work → Adjustable or curved needles.

3. By Fabric Type:

- Lightweight fabrics → Small-bore, rounded-tip needles.

- Heavy fabrics (denim, wool) → Sharper-tip, large-bore needles.
