Prepared For Dyeing (PFD)
Prepared for dyeing (PFD) is textile that has been scoured and bleached to make it suitable for piece dyeing in later processes or garment dyeing.

Definition and Overview
Prepared for dyeing is textile that has had sizing, oils, and other substances removed from woven fabric and has been prepared as fabric for dyeing. PFD is an abbreviation of prepared for dyeing, and is used to refer to prepared for dyeing intended for dyeing.
In particular, prepared for dyeing for garment dyeing is intended for dyeing after cutting and sewing, in the form of the finished product. It is not the name of the fabric structure or material, but a term that describes the processing stage before dyeing and its intended use.
Features
It often appears undyed or in a pale natural tone, and is finished with dyeing results and uniformity in mind. However, whiteness, fuzz, stiffness, and surface feel vary depending on the type of fiber, scouring and bleaching, and any additional processing.
Compared with regular fabric, it is easier to incorporate the changes in texture and appearance after garment dyeing into the design plan. On the other hand, sewing thread, interlining, buttons, and other accessories do not necessarily dye in the same way, and differences in shade after dyeing may become part of the design.
Main Applications
It is used for shirts, blouses, cut-and-sew tops, pants, skirts, dresses, jackets, and similar items when the plan calls for color expression or a washed look through garment dyeing. Depending on the fabric thickness and structure, applications range from spring and summer to autumn and winter.
It is also used for piece dyeing in roll form, but prepared for dyeing sold for garment dyeing should be selected on the premise of dyeing after the sewing process. Garment dyeing is also used when you want to take advantage of differences in appearance created by seams and sewing specifications.
Selection and Handling Notes
When selecting, check the suitability for the intended dyeing method in addition to material, blend ratio, structure, and fabric weight. For not only the fabric but also sewing thread, interlining, zipper, buttons, and labels, confirm heat resistance and dyeability in advance, and verify the finish through prototypes.
In garment dyeing and washing processes, shrinkage, twisting, skewing, and puckering may occur. Allow for dimensional changes after processing in the pattern, and consider grainline, seam allowances, and sewing thread tension. It is important to carry out trial dyeing and laundering tests before full-scale production.
- Check the fabric width and shrinkage rate in the prepared for dyeing state separately from the figures after dyeing and washing.
- Clarify in the specification whether differences in color or deformation in accessories are acceptable as part of the design.
- Confirm that hue and texture may vary depending on the lot and dyeing conditions.
Differences from Similar Terms
Bleaching refers to a process that makes fabric white or clean through scouring, bleaching, and similar treatments. Prepared for dyeing is the term used when such fabric is handled as being in a state suitable for later dyeing. Because the processing differs from fabric to fabric, prepared for dyeing does not mean the same level of whiteness or the same finish.
Piece dyeing is a method of dyeing fabric in roll form after weaving or knitting. In contrast, garment dyeing is a method of dyeing sewn garments. Prepared for dyeing is used for both types of dyeing, but prepared for dyeing for garment dyeing places emphasis on suitability for the latter.
Frequently Asked Questions
Is prepared for dyeing the same as natural-colored fabric?
Not necessarily. Natural-colored often refers to a color tone that looks unbleached or undyed, whereas prepared for dyeing indicates the processing stage before dyeing. Even if the appearance is similar, the degree of scouring and bleaching, suitability for dyeing, and whether any finishing has been applied differ by fabric, so check the specifications.
How much does prepared for dyeing for garment dyeing shrink after sewing?
Because shrinkage varies depending on the material, structure, dyeing method, washing method, and drying conditions, it cannot be determined uniformly. In addition to the shrinkage rate of the fabric alone, dye and wash a sewn sample under conditions close to actual production, then check changes in body length, width, twisting, and similar factors and reflect them in the pattern.
When garment dyeing is done on prepared for dyeing, will the accessories also be dyed?
Dyeing results vary depending on the material and surface treatment of the accessories. Sewing thread, interlining, buttons, zippers, and similar items may not match the fabric in color, or may deform due to heat or chemicals. Decide whether to use color differences as part of the design or use accessories compatible with dyeing, and carry out prior testing.
