Problems and solutions in the jigger dyeing machine process


In the textile printing and dyeing industry, the jigger dyeing machine has become the preferred equipment for many companies due to its high efficiency and uniform dyeing effect. However, in actual production, many operators are troubled by various dyeing problems.

What are the common problems in the jigger dyeing machine process?
  • Color shading, color stains, color difference, weft skew, warp skew, wrinkles, crease, loose – board mark, water marks, etc.

Color shading and stains

What are color shading and stains? Why do they appear on the fabric? How to solve the problem if they occur during the dyeing process of the jigger dyeing machine?
  • Color shading: the color of the fabric is different, with patches or stripes;
  • Color stain: irregular dark stains appear on the fabric.
  • Causes: improper selection of dyes; incorrect use of auxiliaries; improper control of process parameters; incomplete cleaning of equipment.
  • Solutions:
1) Optimize dye selection: Select appropriate dyes according to fiber types to ensure good dyeing results.
2) Correct use of auxiliaries: Add leveling agents and other auxiliaries in strict accordance with process requirements to ensure uniform dispersion of dyes.
3) Accurately control process parameters: Reasonably set the heating speed, insulation time and cooling process to ensure that the dyes are fully penetrated and fixed.
4) Clean equipment regularly: Thoroughly clean the dye tanks and pipes before each dyeing to avoid residues from contaminating new batches.

Color difference

What is color difference? Why does color difference occur during the dyeing process of the jigger dyeing machine? How to solve the color difference problem?
  • Color difference: There are color differences between dyed products of the same batch or different batches, which affects the overall consistency and aesthetics.
  • Causes of color difference: inconsistent dye ratio; changes in process parameters; differences in operator skills.
  • Solution:
1) Strictly control the dye ratio: adopt a standardized dye ratio scheme to ensure that the dye ratio of each batch is consistent.
2) Keep the process parameters stable: reasonably set and keep the process parameters stable during the dyeing process to avoid color differences caused by parameter fluctuations.
3) Strengthen personnel training: improve the skill level and experience accumulation of operators to reduce color differences caused by human factors.

Introduction of Sizing

Image
  Sizing is the process of applying size to warp yarns to improve their weavability. Weavability refers to the ability of warp yarns to withstand repeated friction, stretching, bending and other effects of stop sheets, heddles, reeds, etc. on a loom without causing excessive fluffing or even breakage. Unsized single yarn fibers do not adhere tightly to each other and have more hairiness on the surface, making it difficult to weave. After sizing, part of the sizing liquid penetrates between the fibers, and the other part adheres to the surface of the warp yarn. The sizing that mainly involves the penetration of the slurry into the fibers is called penetrating sizing, and the sizing that mainly relies on the slurry adhering to the surface of the warp yarns is called covering sizing. Ancient manual sizing involves spreading the warp yarns into sheets, applying paste with a brush or reed, drying and then winding them into weaving beams. Wang Zhen’s “Nongshu” of the Yuan Dynasty contain...

Fiber Fineness and Tenacity Test

Image
  Test methods explanation We have tested 5 fiber samples using two solutions to test fiber fineness and tenacity: Solution 1 and solution 2. Solution 1 We use YG002C measured the fiber diameter, and YG005S tested the break force and extension. The fiber density is converted to denier from diameter using the formula. Then use the break force divide the density to get the tenacity. Please move to TABLE 1 to view the test result. We have attached YG002C parameter sheet in Appendix 1 and YG005S parameter sheets in Appendix 2. Solution 2 We use ZK100F measured the fiber density, and YG005X tested the break force, extension, and tenacity. Please move to TABLE 2 to view the test result. We have attached ZK100F parameter sheet in Appendix 3 and YG005X parameter sheet in Appendix 4. A better solution for fiber density and tenacity testing  We also have a YG005XD AUTOMATIC FIBER TENSILE AND FINENESS TEST SYSTEM, which has integrated function of ZK100F and YG005X; it is equipped wi...

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient i...
