8451400000DF241-21 1–5 kg lab cone yarn dyeing machine is designed for package yarn sampling, shade confirmation, recipe testing and small-batch process trials before bulk cone yarn dyeing production. It is suitable for dyehouse laboratories, textile R&D centers, yarn testing rooms and sampling departments that need to test cone yarn in package form before larger production batches.
Compared with beaker dyeing or general laboratory dyeing machine testing, this small-capacity cone yarn dyeing machine allows yarn to be tested as soft package yarn. It provides practical reference for bulk package yarn dyeing machines, especially when cone size, package density, circulation condition and dyeing process may affect final shade result.
DF241-21 helps dyeing factories check color performance, dyestuff behavior and process conditions on smaller batches before bulk package yarn dyeing. It is practical auxiliary equipment for new color development, sample approval, dyestuff and auxiliary comparison, and production process reference.
This lab cone yarn dyeing machine is mainly used for dyehouse laboratory sampling and small-capacity process testing in package yarn dyeing production. Typical applications include:
DF241-21 adopts compact structure with small footprint, making it suitable for laboratory rooms, yarn testing rooms and sampling areas where installation space is limited. Operation is convenient for frequent sample tests, small-batch color checking and process comparison.
Standard reference cone size is 165 mm in diameter with dye tube height of approximately 170–171 mm. Under this reference condition, each soft package is approximately 1 kg. Actual number of packages per batch should be confirmed according to cone diameter, cone height, package density and yarn weight per cone.
Standard configuration uses domestic-brand dyeing control system for sample process setting and operation management. It supports practical laboratory operation for heating, holding and cooling steps during dyeing process.
For customers requiring higher-level control, SEDO control can be supplied as optional upgrade. Final control configuration can be selected according to laboratory management requirement and project budget.
Standard configuration is steam heating. If laboratory has no steam supply, electric heating version can be customized according to project requirement. Electric heating is not standard configuration and should be confirmed before quotation.
Dyeing vessel and main wetted parts are made of stainless steel suitable for textile dyeing applications. Material selection follows practical standard used for larger package yarn dyeing machines, helping ensure durability, corrosion resistance and stable operation during laboratory sample dyeing.
This small-capacity package yarn dyeing machine can be used for polyester, nylon, cotton, acrylic, wool and blended yarns. Polyester and some synthetic yarns may require high-temperature dyeing, while cotton, wool, acrylic and blended yarns should be tested according to actual dyeing process.

For dyehouses that frequently develop new colors, adjust recipes or compare dyestuff performance, laboratory sampling is not only used to obtain small dyed samples. It also helps check dyeing recipe, yarn package condition and process performance before larger production.
Final production result may still be affected by yarn material, package density, loading weight, circulation condition and operation process. Therefore, lab dyeing result should be used as practical reference for bulk dyeing preparation and production adjustment rather than fixed production guarantee.
