“…In addition, the protective properties of textiles can also be significantly improved by adjusting the type, [28] content, [29] particle size, [30] orientation and distribution, [31] and other parameters of the nanofillers. [32][33][34][35] Although such coatings have many advantages for the target application, we discovered that using a continuous coating to cover a textile negatively impacts its flexibility and breathability. As a result, it is still challenging to simultaneously improve the protective performance of personal protective equipment while maintaining its original flexibility and breathability.…”

Functional textiles with desirable protective properties (i.e., high cut‐, stab‐, and abrasion resistance) and wearability (i.e., excellent flexibility and permeability) remain unmet goals for personal protective equipment. Herein, inspired by crocodile skin, a unique and soft‐rigid unified structure (SRUS) is reported by integrating rigid protective blocks onto a soft textile substrate while obtaining a high cut‐, stab‐, and abrasion‐resistant composite textile that is flexible, waterproof, and breathable. Rigid blocks, consisting of epoxy resin reinforced by inorganic powders, strongly adhere to the soft textile surface with small intervals between each other via a pattern‐controllable integrated molding (PCIM) approach. Consequently, the SRUS design guarantees superior protective performance through rigid protective blocks and satisfactory flexibility and permeability via soft textiles and intervals. The SRUS textile achieves excellent cut‐resistance (58 N), the highest grades of stab‐ (38 N) and abrasion‐resistance (600 r mg−1), and good flexibility (65 mN cm) and permeability (60 mm s−1) values, indicating a distinct combination of desirable protective and wearable performance. The proposed SRUS protective textiles, incorporating the PCIM approach, offer a novel strategy for manufacturing functional soft composite textiles that combine high protective performance and good wearability, opening up a new avenue for the development of personal protective equipment.

“…A warp-knitted scale structure was prepared in the same lab, in this case using epoxy resin with SiC particles to impregnate the scales [ 39 ]. They reported an increase in the stab resistance due to the addition of SiC particles, but also mention that the knitted material (here polyester and Spandex) should be changed to a technical yarn, and washing of the composite structure should be tested.…”

Stab-resistant garments have been used for centuries, utilizing metals, paper, or polymeric structures, often inspired by natural structures such as scales. Nowadays, stab-resistant vests or vest inserts are used by police and security personnel, but also by bus drivers, ambulance officers, and other people who are empirically often attacked on duty. Since stab protection garments are often heavy and thus uncomfortable and not well accepted, whether in the form of chain-mail or metal inserts in protective vests, researchers are striving to find lightweight, drapable alternatives, often based on polymeric materials. These research attempts have recently focused on textile fabrics, mostly with impregnation by shear-thickening fluids (STFs) or ceramic coatings, as well as on lightweight composites. The first studies on 3D printed polymeric objects with tailored shapes, as well as theoretical investigations of the stab-protective effect of different materials, have been published throughout the last years. Here, we discuss different measurement methods, including dynamic and quasistatic methods, and correlations of stab-resistance with other physical properties, before we give an overview of recent developments of stab-resistant polymers, using different materials/material combinations and structures.

“…Previous studies have indicated that yarn slip is the primary factor causing cutting or puncture failure of original high-performance ber textiles, and nowadays, coating is one of the most advanced strategies, including shear thickening uid (STF) [27][28][29][30], hydrogel [31][32][33][34], exible resin [2,35,36] and hard particle [37,38]. For instance, Liu [39] designed a new type of stab-resistant fabric based on the warp knitted scale structure by coating epoxy resin reinforced by inorganic powder (Epoxy/IP). Fan [27] treated the fabric with nano-SiO 2 /shear thickening gel (STG), which greatly increased the peak piercing force of the STG-treated fabrics in puncture testing compared to neat samples.…”

This study prepared a soft-rigid unified structure (SRUS) textile composed of inorganic powder (IP) reinforced epoxy resin block (EIPB) array and a soft textile substrate via a pattern-controllable integrated molding method. The effects of IP content and alumina particle size on the cutting and puncture resistance of the resulting SRUS textile were evaluated. The anti-puncture and anti-cutting mechanisms of the SRUS textile were assessed based on the damage morphology and process. The experimental results demonstrated a significant enhancement in the puncture and cut resistance of the SRUS textile after the addition of IP. Moreover, the cut/stab resistance of the SRUS textile increased with the increase of IP content and the size of Al2O3, and the optimal cut/stab resistance was observed at 60 mesh-50 wt.%. The maximum stab and cut resistance of the SRUS textile increased by approximately 19.2% and 62.1%, respectively, reaching the highest protection level when compared to pure SRUS textile. Additionally, the hard passivation at the EIPB and the friction self-locking at the interval were considered to be the anti-puncture mechanism of the SRUS textile, while the anti-cutting mechanism was attributed to the reverse cutting of hard particles on the blade.
