Tricot Machine Case Study: HTS4-EL & HTS3M Bubble Fabric Warp Knitting | A-ZEN

High-Speed Tricot Warp Knitting Machine Case: Bubble Fabric Production

1. Overview: Creative Fabric Realization on HTS4-EL Tricot Machine

Tricot warp knitting machines are engineered to produce smooth, elastic, and structured fabrics at exceptionally high production speeds. Depending on fabric construction and application requirements, A-ZEN provides two primary series: HTS3M (3-bar tricot machine) and HTS4 (4-bar tricot machine).

As a high-speed tricot machine equipped with 4 guide bars and an advanced electrical drive system, the HTS4-EL model has achieved widespread market recognition. In 2020, A-ZEN successfully developed the 290” wide HTS4-EL specifically for producing trendy bubble elastic fabrics. Delivering a massive daily output of nearly 900 kg per 24 hours, the 290” HTS4-EL has built a solid reputation for productivity and market profitability.

2. Key Technical Features & Machine Comparison

To ensure high-speed stability at 1,200 – 1,900 rpm, the HTS4-EL 290" E28 machine integrates top-tier international components:

• Carbon Fiber Elements: 4 guide bars and needle beds are constructed from lightweight, high-strength carbon fiber material to minimize thermal expansion and vibration.

• Control & Drive System: Powered by the Yaskawa (Japan) EL electronic guide bar drive system for flexible pattern shifting.

• Knitting Elements: Equipped with Groz-Beckert compound needles, alongside Saxonia guide needles, tongue needles, and sinkers.

A-ZEN Tricot Machine Series Comparison:

• HTS3M Series: 3 guide bars, high cost-efficiency, ideal for plain tricot fabrics, mesh, and lining textiles.

• HTS4 / HTS4-EL Series: 4 guide bars, high-speed electronic shogging (EL), designed for complex structures such as 3D bubble fabrics, sportswear, and elastic textiles.
