Development and performance study of a natural silk fiber facial mask paper

Abstract

Facial masks are beauty products which composed of a facial mask paper and beauty solution. Silk contains the amino acid structure closest to the human skin, and has the skin-friendly, cosmetic and antibacterial functions, but the common method for making nonwoven facial mask paper is not suitable for silk. In this paper, the silkworm’s spinning path is intervened manually to obtain a smart silk facial mask paper (SMC) of controllable thickness, so that the sericin on the silk fiber is well preserved. In the experiment where the SMC is compared with the nonwoven 384-cuprammonium rayon facial mask paper (CRMC) which is the most widely used in the market, it is found that the ways of forming the two facial mask paper are completely different, and therefore the morphologies under SEM are obviously different. The thickness of the SMC is 0.183 mm and the areal weight of it is 38.0 g/m2. It is very close to the CRMC (0.187 mm, 38.4 g/m2). The porosity of the SMC is 84.0%, which is slightly lower than that of the CRMC (86.3%), but its pores are well distributed. Compared with the CRMC, the smart SMC has higher dry and wet strength, lower elongation, slightly lower air permeability and liquid entrainment rate, and better antibacterial performance.

Silk/Rayon Webs and Nonwoven Fabrics: Fabrication, Structural Characteristics, and Properties

“…Figure 3 displays the results of measuring the porosity of the silk/rayon web and nonwoven fabric in this study. The porous web and nonwoven fabric are widely used in cosmetic (e.g., mask pack) [17,18] and biomedical applications (e.g., wound dressing [8,9] and membrane for guided regeneration [12][13][14][15]) because they can hold more water [38] and allow cell adhesion and proliferation [39][40][41] through their pores. In addition, the porosity influences the mechanical properties of porous materials [32,42].…”

“…Silk exhibits good biocompatibility [ 1 , 2 ], excellent cytocompatibility [ 3 ], a low inflammatory response in the body [ 4 , 5 ], and biodegradability [ 6 , 7 ]. Because of these unique properties, silk has been studied for its application as a wound dressing [ 8 , 9 ], nerve conduit [ 10 ], tympanic membrane [ 11 ], membrane for guided bone regeneration [ 12 , 13 , 14 , 15 ], artificial heart value [ 16 ], and artificial mask pack [ 17 , 18 ].…”

Bioinspired Janus All-Natural Electrospinning Membranes with Directional Water Transport as Ecofriendly Dry Facial Masks

“…Conventional facial masks are made of the nonwoven substrate soaked with liquid active ingredients. The inner wet environment requires antibacterial agents, preservatives, and emulsifiers to extend the guarantee period . Wet facial masks need to be packed in nonbiodegradable plastic barrier packaging.…”

“…The inner wet environment requires antibacterial agents, preservatives, and emulsifiers to extend the guarantee period. 22 Wet facial masks need to be packed in nonbiodegradable plastic barrier packaging. After their use, landfill and incineration are the main end-of-life options.…”

Structure and properties of flat cocoon silk after silk reeling

“…However, due to the differences in varieties of Bombyx mori silkworms, the amount of silk production will be different. The way of body movement and the change of place during silk spinning will have an impact on the shape and the properties of cocoons [15][16][17][18]. If the silking place is limited to two-dimensional space, mature Bombyx mori silkworms can hardly find the best place of cocooning and will spin out a piece of silk on a flat surface, which is the so-called flat cocoon.…”
