Study on the effect of the sanitary properties of microfiber synthetic leather base by using a filling agent

Abstract

In the manufacturing process of the microfiber synthetic leather, various types of filling agents were selected to fill the microfiber synthetic leather base to improve the sanitary properties, in which a zirconium tanning agent was used commonly. In this study, the softness, moisture absorption, water vapor permeability and mechanical properties of the base were used as indexes, and the type and dosage of the filling agent were optimized. The results indicated that the sanitary properties of the base treated by the filling agent were improved generally compared with that of the blank base. Among them, the moisture absorption increased by 28–45%, the water vapor permeability increased by 50–56% and the mechanical properties were significantly improved. The bases before and after being filled were characterized by Fourier infrared spectroscopy, the water contact angle, atomic force microscopy, scanning electron microscopy and the specific surface area. The results showed that the filling agent’s cross-linking effect on the base fiber led to the active group content and wettability of the base increasing, the fiber surface structure changing obviously and the fiber gap becoming larger with looser dispersion. Moreover, the specific surface area of the base increased.

Construction of Collagen Methacrylamide Microspheres to Modify Nonwoven Polyamide Fibers Based on Click Chemistry

“…The polyamide fiber is a kind of synthetic fiber with the molecular chain composed of the repeated amide group (CONH) as well as −COOH and −NH 2 at the end of the molecular chain . Compared with cotton, the polyamide fiber nonwoven material has poor moisture absorption performance and stuffiness. − Collagen with many hydrophilic groups modified on polyamide fiber nonwoven materials can effectively improve moisture permeability. − Based on the morphological characteristics of microspheres, the leather waste collagen in the form of microspheres was modified on the polyamide fiber nonwoven material, which can not only keep collagen off the original voids on the material but also greatly improve moisture permeability.…”

Construction of a Novel Substrate of Unfigured Islands-in-Sea Microfiber Synthetic Leather Based on Waste Collagen

“…A series of studies − have been carried out to improve the moisture permeability of microfiber synthetic leather substrates, but the studies have focused mainly on modifying the surface of polyamide fibers by introducing a large number of hydrophilic groups to improve the moisture absorption and permeability of the substrates. However, a few studies have been reported on modifications or substitution studies around polyurethane fillers.…”

Pengaruh pemlastis dioktil ftalat terhadap sifat fisis dan mekanis kulit sintetis

“…Pembuatan kulit sintetis dapat menggunakan bahan baku polimer beragam, antara lain PVC (Musthofa et al, 1997), PU, poliamida (Liu et al, 2015;Qiang et al, 2017;Roh et al, 2013), akrilik, atau polyester (Ho, 2015). Basis polimer perlu ditambahkan bahan pembantu seperti pemlastis, penstabil, bahan pengisi, pigmen serta bahan penguat untuk mendapatkan kulit sintetis dengan sifat fisis dan mekanis yang diinginkan.…”
