Product Overview

The KR‑839A computer‑controlled infrared medium‑sample dyeing unit is developed for textile‑dyeing laboratories for medium‑batch dyeing trials and washing‑resistance testing. It processes yarn, fabric strips, laces, zippers, ropes and small accessory components such as buttons.

Adopting infrared radiation heating technology combined with rotary‑cylinder circulation, it reproduces actual factory dye‑bath conditions in lab environment. Operators validate dye formulas, test color‑fastness performance and optimise process parameters before mass‑scale production. The machine is well‑received by dye‑finishing plants, textile R‑D centres and textile‑related educational institutions for medium‑size sample‑batch processing.

Core Product Competitive Advantages

1. Corrosion‑Resistant SUS316 Dyeing Vessel with Integrated Safety Design Main dyeing cylinder is constructed from premium SUS316 stainless‑steel, resisting erosion from diverse dye liquors and chemical auxiliaries. Built‑in temperature‑sensing probe requires no frequent disassembly. Equipped with safety‑valve over‑pressure‑protection mechanism. Fixed‑cylinder layout eliminates heavy‑tank hoisting operations for easier sample loading‑unloading. Rated tank capacity reaches 30 kg for 1‑3 kg textile sample batches.
2. Robust SUS304 Whole‑Machine Housing & Safe Pneumatic Upper Lid Outer cabinet adopts SUS304 stainless‑steel sheets, anti‑fouling and easy‑to‑wipe for dye‑lab messy working‑scenarios. The upward‑pull pneumatic cover avoids pinching‑hazards to lab operators during opening‑closing cycles.
3. Programmable Multi‑Segment Process Curve Control LCD‑based intelligent controller supports forward‑reverse rotary running logic. Up to 99 groups of independent temperature‑time process profiles can be stored and quickly recalled, enabling one‑touch execution of complex dyeing‑programs.
4. Efficient Infrared Heating plus Forced‑Convection Air‑Cooling 6 kW infrared heating tubes deliver uniform radiant heating onto the rotating cylinder body. After dyeing cycles finish, forced convection air‑cooling speeds down system temperature, shortening interval waiting‑time between successive test‑batches.
5. Variable‑Frequency Adjustable Rotary Transmission System 370 W geared‑motor with frequency‑conversion drive enables stepless rotational‑speed adjustment from 0‑50 rpm. Stable cylinder‑rotation ensures dye‑liquid circulates fully around textile specimens for even dye uptake across medium‑sized sample lots.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Inspect machine condition, safety‑valve status and pneumatic‑lid function. Place textile samples inside SUS316 dyeing cylinder, inject prepared dye‑bath solution, fasten cylinder sealing‑components. Mount cylinder into machine inner‑chamber. Power‑on unit, recall or edit target dyeing‑process curve on LCD control panel.
2. Dye‑Cycle Execution Close pneumatic upper‑lid, start program. Infrared heating system ramps‑up temperature as programmed; geared‑motor drives cylinder to rotate forward‑and‑reverse continuously for full liquor circulation. System follows stored time‑temperature profile automatically.
3. Forced Cooling Phase Upon completion of heating‑holding segments, machine switches to forced‑air cooling mode to lower cylinder temperature down to safe‑handling level.
4. Sample Unloading After cooling‑procedure finishes, open pneumatic cover, take out dyeing cylinder. Release seal, retrieve dyed textile specimens for subsequent washing, colour assessment or physical‑property testing.
5. Post‑Test Tidying Clean residual dye‑liquor and chemical residues inside cylinder and chamber. Keep lid open for ventilation. Shut‑off main‑power‑supply after finishing‑all‑batches. Regularly inspect safety‑valve, sealing‑rings and infrared‑heating tubes.
