Grass Yarn Twisting Machine

Product Overview

The Grass Yarn Twisting Machine is a specialized piece of equipment designed to meet the demanding needs of yarn processing, particularly for artificial grass production. Developed by JDS Textile Machinery Co., Ltd., a leading manufacturer in the industry, this machine excels in twisting both mono-filament straight grass yarn and curly grass yarn with precision and efficiency.

Available in multiple models—including HDRT-721A, HDRT-721B, HDRT-722, and HDRT-723—it caters to diverse production scales. The most commonly used variant is the 6-spindle model, though options range from 6 to 196 spindles (e.g., HDRT-721A offers 16 spindles per group with a maximum of 196 spindles). A key advantage is its ability to complete both stranding and twisting in a single operation, eliminating the need for multiple machines and significantly boosting production throughput.

Engineered for high performance, the machine operates with spindle speeds ranging from 1800-6760rpm (depending on the model) and supports a twist range of 28-275T/m, ensuring versatility across different yarn types and thicknesses. Its design prioritizes energy efficiency, with a motor power as low as 7.5KW (equipped with frequency conversion for optimal control), and features low noise levels, making it suitable for various factory environments.

Product Features

High Efficiency & Integrated Processing

Unlike traditional machines that require separate steps for stranding and twisting, this Grass Yarn Twisting Machine combines both processes into one, reducing production time by up to 40%. This integration minimizes material handling and ensures consistent yarn quality, as the entire process is controlled within a single system.

Versatile Model Range

With models tailored to different production needs:

HDRT-723 (6 spindles/group, max 54 spindles) is ideal for small to medium batches, handling yarn diameters of 2.5-3mm.

HDRT-721A (16 spindles/group, max 196 spindles) suits large-scale production, accommodating finer yarns (0.5-1mm) with spindle speeds up to 6760rpm.
Each model features adjustable parameters, such as traverse (ring rail stroke) ranging from 300-350mm, to adapt to specific yarn requirements.

Precision & Control

Equipped with advanced controllers, the machine offers precise twist adjustment, with a built-in twist range setting that ensures uniformity across all yarns. Spindle direction (Z or S) is customizable, allowing manufacturers to meet unique product specifications. The feet trample type brake ensures quick stops during operation, enhancing safety and reducing material waste.

Durable & Low-Maintenance Design

Key components are built to last: the down roller (Φ61mm) undergoes hard chrome plating for wear resistance, while spindle parts (e.g., Φ70mm spindle dish dia, Φ35mm spindle pole dia) are made from high-strength materials. The machine’s structure (dimensions up to 7600×1200×2000mm, with customizable creels) is designed for easy access during maintenance, reducing downtime.

Applications

The Grass Yarn Twisting Machine is widely used in the production of artificial grass and related textiles, supporting a variety of materials:

PE yarn (polyethylene), commonly used in outdoor artificial lawns for its weather resistance.

PP yarn (polypropylene), favored for its durability in sports fields.

PET yarn (polyethylene terephthalate) and nylon yarn, ideal for high-traffic areas like playgrounds and golf courses.

It is suitable for both primary twisting and re-twisting processes, making it a versatile solution for manufacturers producing straight or curly grass yarns. Whether for residential landscaping, sports surfaces, or commercial green spaces, this machine ensures the yarns meet the required strength, elasticity, and aesthetic standards.

FAQ

What materials can the Grass Yarn Twisting Machine process?

The machine is compatible with PE yarn, PP yarn, PET yarn, and nylon yarn, covering most materials used in artificial grass production. It handles yarn diameters from 0.5mm to 3mm, depending on the model.

How does the machine ensure consistent twist quality?

Each model is equipped with a precision controller that maintains the set twist range (28-275T/m). Additionally, uniform spindle speeds (e.g., 1800-2100rpm for HDRT-723) and stable traverse movements prevent variations in yarn tension.

Is the machine customizable for specific production needs?

Yes. JDS Textile Machinery offers customization options, including creel design (tailored to customer requirements) and spindle configurations. This allows adaptation to unique factory layouts and production volumes.

What after-sales support is provided?

JDS provides comprehensive after-sales services, including installation guidance, spare parts supply, and technical troubleshooting. The machine also comes with a warranty to cover manufacturing defects.
