Asked Questions (FAQ)

FOOD TEXTILE's Features

FOOD TEXTILE achieves a hybrid dyeing method that combines over 90% natural dyes with chemical dyes, utilizing a patented technology (patents obtained both domestically and internationally). This innovation prevents color fading from traditional washing, allowing for long-lasting use. Additionally, it ensures full traceability from raw materials to finished products. Beyond the scope of typical CSR activities, FOOD TEXTILE supports companies in confidently engaging with these initiatives as a viable business endeavor.

Is it possible to only provide food ingredients?

We are grateful to receive many offers for providing food ingredients, but we are not currently recruiting partners who only provide food ingredients. We only accept partners who are willing ingredients to consider utilizing unavoidable food waste from their own operations and work towards productization.

Is it possible to use any type of food material?

There are certain suitability factors for use as dye, but as long as the material is not processed or excessively high in moisture, it can be used for dyeing.

Do uneven coloring or variations occur?

We manage the process to prevent uneven coloring or variations, but the quality of vegetables changes every year. Factors such as lighter colors in the ingredients compared to previous years, diseases affecting growth, and other various reasons can cause the dyeing to become lighter or darker. We adjust the varying conditions of the ingredients depending on the season by controlling the pH to maintain consistency.

Is there any "odor" in the product?

The odor is eliminated during the dyeing process, so it is "odorless."

How long is the lead time for dyed fabrics?

Since it involves a special technique, it takes longer than regular chemical dyeing.

*The sewing period depends on the product, but it will take an additional 2 months or more to the above-mentioned period.
(Example: If dyeing with original residue and making it into a product → Approximately 5 months.)

Does the color fade?

The dyeing process of the FOOD PROJECT uses over 90% natural dyes, with the remaining few percent consisting of chemical dyes. This ensures that all fabrics pass the color fastness test (durability of color). This technology is entirely developed in Japan and has been patented not only domestically but also in several other countries.

※ Compared to chemical dyes, it may be less resistant to light (degradation caused by exposure to light) or chlorinated water (used in tap water or pool disinfection).
