# Exploring the Green Design of Hakka Cultural Creative Textiles for Sustainable Development
###### Abstract  
This study explored Hakka cultural creative textiles using the green design concept, the cultural creative product design model and [PERSON]'s three-component unifying metatheory based on ideology, social structure and technology to analyse the effect of blue dye colour, floral pattern size and pattern type on the preference for natural indigo dyed and stonewashed Tung blossom denim. Two hundred and twenty-nine subjects aged 18-24 years (\(M=19.5\), \(SD=1.25\)) participated in this study. The results demonstrate that the main effect of blue colouring was significant and that Hanaasagi and Ai-iro were the most preferred colours. The main effect of floral pattern size was significant, and the subjects exhibited the strongest preference for the large size and the weakest preference for the extra-small size. The main effect of pattern type was also significant, and the subjects' preference for the two-dimensional repetitive pattern was always stronger than that for the one-dimensional repetitive pattern. These results show that green design may be combined with cleaner production, such as using natural indigo as a raw material for sustainable development, to create new luxury fashions of cultural creative textiles for consumption.

migrations and this group's pioneering spirit [3]. Regarding their dress, [PERSON] et al. [4] noted that the most representative Hakka clothing item is the \"blue dress\" (blue blouse), which is the traditional garment worn by Hakka women. From a material perspective, the \"blue dress\" has a durable and solid texture, and its cotton fabric is suitable for a subtropical climate environment, consistent with the needs of local residents [5]. Second, regarding social structure (including social behaviour), according to Taiwan's official survey data, the Hakka population, estimated at over 4.53 million, is the second-largest ethnic group in Taiwan, accounting for 19.3% of Taiwan's total population [6]. [PERSON] and [PERSON] [7] showed that the world's Hakka population is approximately 65.624 million, of which 61.078 million (93%) are in China and 4.546 million (7%) are overseas, indicating that Hakka people have become one of the world's important ethnic groups. From more than a thousand years of migration hardship experience, the Hakka people generally exhibit fine traditional characteristics, such as diligence, thrift, contentment, a tendency to choose what is good and hold fast to it, a hardworking nature, cooperation, hospitality, engagement in actions that suit local circumstances, etc. [8], which are also unique social behaviour manifestations of the Hakka people. In terms of the mechanism of government and economic organizations, the Hakka Affairs Council in Taiwan has been promoting the Hakka Tung Blossom Festival and, thus, the development of the Hakka cultural industry since 2002 [9]. [PERSON] [10] argued that Hakka images may be appropriated to generate capital, an opportunity that has been validated by the Hakka Tung Blossom Festival. [PERSON] and [PERSON] [11] found that the distribution of Tung Blossom and the region where the Hakka people reside are highly correlated and that the features of the Tung Blossom (e.g., its shape, colour, flowers, growth characteristics, and low profile) are consistent with the characteristics of the Hakka people. Therefore, the Tung Blossom is a fitting visual image to represent the Hakka people. Third, regarding technology, it refers to material culture, to the physical things used in adaptation to one's physical and social environment in the cultural system [1]. Taking the textile industry and denim fabric as an example, nearly 60% of the world's jeans are produced in Mainland China. \"Chemical blue dyeing\" of denim requires the use of azo dyes. Some of these dyes degrade during the dyeing process and release aromatic amines that may be carcinogenic [12].
