A novel, waterborne polydimethylsiloxane (PDMS)-modified polyurethane-acrylic (Si-PUA)/pigment hybrid emulsion was synthesized by one-step miniemulsion polymerization for the pigment printing of polyester fabric. The phase structure, hydrophobicity, and thermal and mechanical properties of the formed films with different PDMS contents from the hybrid emulsion were investigated. The results indicated that the pigment particles were uniformly distributed in the homogeneous phase polymer substrate without phase separation occurring between the PDMS phase and polyurethane-acrylic. The hydrophobicity and toughness of the Si-PUA/pigment hybrid latex films gradually increased with the increase of PDMS content. Moreover, the obtained hybrid emulsion was used as a self-curable hybrid pigment that was applied to polyethylene terephthalate fabric for pigment printing. This showed that the Si-PUA/pigment hybrid latex particles yielded similarly good values in terms of color strength, and dry- and wet-rubbing fastness to the PDMS-free hybrid latex particles. Furthermore, use of the Si-PUA/pigment hybrid latex avoided certain problems related to printed fabric, such as poor air permeability and softness.

“…Aminolysis with ethylenediamine for a short time in ambient conditions results in the creation of both amine and carboxylic acid functional groups on the polyester fiber surface, which provides a possibility for better finishing effects [18,[32][33][34]. Hydrolysis can be performed with alkaline and enzymes [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]. The mechanism of hydrolysis is shown in Figure 1.…”

“…In harsher processing conditions, cracks and often holes occur, suggesting fabric damage [6][7][8][9][10][11][12][13][14][15][16][17][18]. By controlling the processing time, it can be used to engineer sub-micro roughness (also called alkali etching) on a fiber surface to make superhydrophobic, self-cleaning textiles [45][46][47][48][49].…”

Sustainable Alkaline Hydrolysis of Polyester Fabric at Low Temperature

et al. 2022

High crystallinity leads to low hydrophilicity of fabric made of (poly(ethylene terephthalate)) fibers (PET) causing problems in finishing, washing, and dyeing processes. To improve these properties, the surface of PET fibers is usually modified by hydrolysis. Alkaline hydrolysis is a conventional process usually performed at a temperature higher than 100 °C for more than 1 h. However, the use of strong alkali and high processing temperatures (>100 °C) can lead to fabric damage and a negative impact on the environment. Therefore, in this paper, the possibility of hydrolysis of the PET fibers in the fabric in a sustainable, energy-efficient process was researched. The influence of low temperature (60–100 °C) and an accelerator (a cationic surfactant HDTMAC) to PET alkaline hydrolysis was studied through weight loss, the loss in breaking force, and fiber morphology. The kinetics of PET dissolution in 1.5 mol cm−3 NaOH at low temperature with and without the addition of HDTMAC was determined and the activation energy was calculated according to the theoretical model. It has been confirmed that PET hydrolysis can be carried out in 1.5 mol cm−3 NaOH with the addition of HDTMAC as an accelerator at 80 °C for 10 min. This process is more economically and energetically acceptable than the conventional process, and is therefore more sustainable.

“…Therefore, it is necessary to simulate a gravel environment in practical applications to evaluate the performance of the coatings. Sand washing, a typical experimental method, is typically used to evaluate the durability of coatings [43]. Based on the above analysis, the sand-washing experiment was adopted to simulate the gravel test in practical applications.…”

Stable and Durable Conductive Superhydrophobic Coatings Prepared by Double-Layer Spray Coating Method

et al. 2021

Herein, a low cost, durable, and stable conductive superhydrophobic composite coating (CSC coating) was fabricated on a Q345 steel surface by simple double-layer spray coating. The water contact angle (WCA) of the CSC coating was 160° and the sliding angle (SA) was 3°. In addition to its excellent conductivity (3.10 × 103 Ω), the fabricated composite coating had good durability and wear resistance. After 10 sand-washing cycles, the CSC coating surface still exhibited stable superhydrophobicity (149° WCA, 9.5° SA). At 200 g pressure, the surface of the optimized CSC coating still maintained fine superhydrophobicity (150° WCA, 9.2° SA) and conductivity (1.86 × 104 Ω) after 10 abrasion cycles. In addition, it also exhibited fine adhesion (0.307 MPa) between the composite coating and the substrate. This functional superhydrophobic surface can be applied in specialty fields with harsh conditions such as coal mining and petrochemical activities. This new coating may also expand the application fields of superhydrophobic surfaces and have broad practical application prospects.
