Sample Cone Yarn Dyeing Machine

Sample Cone Yarn Dyeing Machine

A Sample Cone Yarn Dyeing Machine is a lab-scale dyeing unit designed for dyeing small batches of yarn wound on cones. It simulates the bulk cone dyeing process, allowing testing of dye formulations, shade matching, and process development before large-scale production.

Purpose Sample Cone Yarn Dyeing Machine:

To dye yarn cones under controlled conditions using a small quantity of dyes, water, and chemicals.

Working Principle Sample Cone Yarn Dyeing Machine:

Yarn cones are mounted on dyeing spindles.

The dye liquor is circulated through the yarn from inside (inward flow) or outside (outward flow), ensuring uniform penetration.

Temperature, pressure, and time are controlled digitally.

Applications of Sample Cone Yarn Dyeing Machine:

Lab trials in dye houses

R&D in dye and chemical manufacturing

Shade and recipe matching

Process optimization before bulk production

Benefits of Sample Cone Yarn Dyeing Machine:

Cost-Effective Testing – Uses minimal dye, water, and energy for trial batches.

Accurate Shade Development – Matches production dyeing conditions for reliable color matching.

Quick Recipe Validation – Fast testing of dyeing recipes before bulk production.

Time Saving – Rapid cycle time helps speed up R&D and approvals.

Versatile Applications – Suitable for different yarn types: cotton, polyester, blends, etc.

Improved Quality Control – Identifies dyeing issues early in lab conditions.

Features of Sample Cone Yarn Dyeing Machine:

Compact Design – Lab-friendly, space-saving build.

Digital Controller – Precise control of temperature, time, and pressure.

Reversible Flow System – Ensures uniform dyeing by alternating liquor flow.

Stainless Steel Construction – Durable and corrosion-resistant.

Pressure & Temperature Safety Devices – For safe high-temperature operations.

Easy Loading & Unloading – Designed for quick cone placement and removal.

How to Use Sample Cone Yarn Dyeing Machine:

Prepare the Yarn – Wind yarn uniformly onto dye able cones (perforated cones preferred).

Load the Machine – Mount the cones on dyeing spindles and secure the lid properly.

Add Dye Liquor – Fill the tank with water, dye, auxiliaries, and chemicals based on the recipe.

Set Parameters – Use the digital controller to set: – Dyeing temperature – Holding time – Heating rate   – Flow direction (inward/outward)

Start Dyeing Cycle – Begin the process; the machine will heat and circulate dye liquor.

Monitor the Process – Watch for pressure, temperature, and flow direction changes if applicable.

Cool Down & Drain – After dyeing, allow the machine to cool. Drain the bath and rinse the yarn.

Unload and Dry – Remove the cones carefully and dry them using a hydro extractor or dryer.

Safety Tips for Sample Cone Yarn Dyeing Machine:

Use Heat-Resistant Gloves – Always wear gloves when handling hot parts or dye liquor.

Secure the Lid properly – Ensure the lid is tightly closed before starting to avoid leaks under pressure.

Avoid Overloading – Do not exceed the recommended cone or liquor load to prevent uneven dyeing or damage.

Stay Clear During Operation – Keep hands and tools away from moving or hot parts while in use.

Ventilation – Operate in a well-ventilated area to avoid inhaling steam or fumes.

Emergency Stop – Know the location and function of the emergency stop button.
