Summary

Dyeing gives textile materials their color while aiming to make that color last through use and care. This lesson introduces how dyes attach to fibers, traces the history of dyeing, and explains how dyes are selected.

Dyeing is the application of dyes or pigments to textile materials such as fibers, yarns, and fabrics to achieve a desired color and degree of color fastness. It is commonly carried out in a solution containing dyes and other chemicals. Dye molecules attach to fibers through processes such as absorption, diffusion, or bonding. Temperature and time are important controls because they affect how dye moves into and interacts with the material.

All flashcards

What is dyeing?
Applying dyes or pigments to textile materials to achieve a desired color and degree of color fastness.
How can dye molecules attach to fibers?
Through absorption, diffusion into the fiber, or bonding; time and temperature help control the process.
What is color fastness?
A textile material’s resistance to color change or transfer during exposure to washing, rubbing, light, or similar conditions.
What is dope dyeing?
Adding pigment to a synthetic polymer solution before the fiber is extruded.
What is space dyeing?
Applying color in localized areas along a material to create a multicolored effect.

Quiz questions

  1. What was mauveine, and who created it?Answer: The first synthetic dye, created by William Perkin in 1856.
  2. Why can indigo on cotton denim help produce a washed-down effect?Answer: Its relatively poor wash and rubbing fastness allows color to leave the denim.
  3. Compared with continuous dyeing, what is a characteristic of exhaust dyeing?Answer: It uses more water and transports dye to the material through moving dye liquor.
  4. Which dye classes can be used on cotton when excellent washing fastness is needed?Answer: Vat or reactive dyes.
  5. How may dye liquor move through yarn packages during package dyeing?Answer: It may flow alternately from the inside outward and from the outside inward.
