The utilization of blockchain technology and its subproduct smart contract could transform the second-hand fashion market value by solving problems related to fake products or fraud, and absence of total disclosure. This paper introduces DMarket, a decentralized marketplace that would enable usage of blockchain based smart contracts for trading and authenticating second-hand fashion. DMarket’s implementation of the blockchain technology is well driven towards increasing the level of trust and security on the platform by guaranteeing product and transaction integrity. That represents a product’s authenticity, the handling of an escrow payment and other aspects of a transaction are all governed by smart contracts thus ensuring that all stipulations on the contract are met before the transaction can go through. In this paradigm, findings have shown us that DMarket enhances security and transparency than conventional second-hand fashion marketplaces. DMarket eliminates the consequences such as fraud and usage of counterfeit products since it captured product data and transaction history on the public ledger. Improved customer trust is apparent by their satisfaction as well as confidence in transactions. In conclusion, this paper is in agreement with the idea that blockchain technology and smart contracts present the second-hand fashion e-market place with an efficient solution to its problem, hence fostering the development of more secure e-business platforms. As such, future research should focus on augmenting the features of platform and identifying possibilities for its future expansion.

The effect of yarn density of color textiles on the visual impression evaluation of double-piled textiles was examined. Four yarn densities and six textile colors were prepared for cotton fabrics and piled on a black or white paper. The semantic differential method was applied for the evaluation with 14 pairs of adjectives, and revealed that the score of the impression evaluation was linearly correlated to the area void fraction of the covering fabric. The examination of the relation between the correlation factors and covering-underlying color combinations resulted in the following: (1) The impression evaluation worsened as the underlying color became more transparent, independent of the color combination between the covering and the underlying paper; (2) The evaluation score was strongly dependent on the yarn density and the values or hues of the colors.
