“…The dyed PLA fabrics displayed better sublimation fastness than dyed PET and PA 6.6 fabrics. 117 Novel phenylazopyrazolone-containing acylamide disperse yellow dyes were designed and synthesized for PLA, based on the prediction that some polar groups build stronger force between dyes and PLA macromolecular chain. The dye sorptions changed depending on the types of acylamide dyes.…”

Poly(lactic acid) (PLA) fiber was developed more than a decade ago. It has been regarded as the most promising sustainable and biodegradable fiber to replace conventional polyethylene terephthalate (PET) polyester fiber in textile products. This paper reviews recent developments in PLA polymerization, PLA filament and fiber spinning, staple yarn spinning, fabric production, dyeing and finishing and aftercare procedures. The properties of PLA fiber are broadly similar to those of PET fiber; however, the properties of PLA fiber that differ, including thermal degradation and low hydrolytic resistance to strong alkaline, significantly affect the method selection and parameter setting of production and processing of PLA fibers and fabrics. PLA filaments are mainly produced by two-step melt spinning to get fibers with stable quality, but degradation at high temperature is still a problem. PLA staple yarns are normally spun using ring spinning. Currently existing knitting or weaving techniques can be used to produce PLA fabrics. PLA fabrics can be dyed with disperse dyes at 110°C, but their color fastness and shades are different from PET fabrics when using the same dyes. The scouring and dyeing of PLA/cotton blended fabrics and the reductive clearing after dyeing remain to be improved. As a new fiber, the entry of PLA fiber into the textile market faces difficult challenges as well as great opportunities in the future.

Monosubstitute thiazolyl amines were diazotized in acetic acid, coupled to 1-phenyl-3-aminopyrazol-5-one (1a-1c) and acetylated to obtain the 2a-2c dyes. The dyes were characterized by elemental analysis and spectroscopic (Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), ultraviolet (UV)) methods. The effects on the visible absorption spectra of the substituents present, solvents, pH, concentration and temperature were investigated in detail. Tautomerism of the dyes were investigated by spectroscopic methods. Fastness properties of dyes were studied using the standard method for the assessment of color fastness of textile.

“…Second, unique soft texture is one of the most important advantages of silk, so the fragrance-loaded systems should also be soft. − Third, silk is frequently washed, so the fragrance-loaded systems should hold on the silk in the alkalescent washing condition. Fourth, silk is usually made into costumes that go next to the skin, so the fragrance should be released in the acidic perspiration conditions. − Fifth, the surface of silk is negatively charged, so the fragrance-loaded systems with positive charges are more easily adsorbed on the surface of silk because of the electrostatic interaction. With the developments of nanoscience and nanotechnology, preparation of nanoencapsulated fragrances is expected to meet these above requirements. − …”

Aromatherapy is widely used in the treatment of diseases of the central nervous system, such as depression and anxiety. However, the rapid and uncontrolled release of aroma weakens the effects of aromatherapy. In this study, zwitterionic polymer-based nanoparticles encapsulated with linalool were prepared to improve the regulation of the central nervous system. First, the nanoparticles were modified with positive charges to adhere to the surface of silk via electrostatic interactions between the cationic nanoparticles and anionic silk. Besides, the fragrance was sustainably and controllably released from the nanoparticles. The effects of polymerization degree, polymer structure, and zeta potential on encapsulation efficiency, adhesion efficiency, and release profiles of linalool were then explored. The results showed that the linalool-encapsulated nanoparticles had the best performances of encapsulation, adhesion and release of fragrance when the polymerization degrees of hydrophilic block and hydrophobic block were 20 and 5, respectively. In addition, open field tests evaluated the regulation of nanoparticles on the central nervous system at the behavioral level. Measurements of dopamine, acetylcholine, and γ-aminobutyric acid expressions explored the mechanism of moderating effects on the central nervous system at the molecular level.
