Overview of the application of nanotechnology in textile function enhancement
Nanotechnology, as one of the revolutionary science and technology in the 21st century, is profoundly changing the functional attributes and application fields of traditional textiles. By introducing nanomaterials into the textile manufacturing process, the physical, chemical and biological properties of the materials can be significantly improved, opening up new possibilities for the development of functional textiles. As an innovative functional textile, the inter-cotton composite TPU anti-slip fabric is a concrete manifestation of this technological progress. This product achieves excellent anti-slip performance, excellent wear resistance and good comfort by combining nano-grade modified polyurethane (TPU) with natural cotton fibers.
In modern industry and daily life, the application demand for anti-slip materials is growing. From the safety protection of industrial equipment to the design improvement of household products, to the professional development of sports equipment, all of which put forward higher requirements for anti-slip materials. Traditional anti-slip materials often have problems such as insufficient wear resistance, short service life or poor comfort, and the introduction of nanotechnology provides effective solutions to these problems. By precisely controlling the size, morphology and distribution of nanomaterials, it can significantly improve its functional performance while maintaining the original characteristics of the material.
This article will conduct in-depth discussion on the specific application methods of nanotechnology in intercotton composite TPU anti-slip fabrics, analyze its mechanism to improve material performance, and explain in detail with practical application cases. At the same time, the key parameter indicators of the product will be introduced, and the advantages over traditional anti-slip materials will be demonstrated through comparative analysis. This innovative material not only meets the needs of modern industry and life, but also points out a new direction for the development of functional textiles.
Technical principles and structural characteristics of inter-cotton composite TPU anti-slip fabric
The inter-cotton composite TPU anti-slip fabric adopts an advanced multi-layer composite structure design, consisting of a surface nanomodified TPU coating, an intermediate reinforcement layer and a base natural cotton fiber substrate. At the microscopic level, the material adopts a unique “sandwich” structure: the top layer is a microporous network structure composed of surface-modified nanoscale TPU particles, which are evenly distributed on the surface of the substrate through chemical bonding, forming a dense The uniform anti-slip coating; the intermediate layer is a reinforced mesh woven from high-strength fibers, which plays a supporting and stabilizing role; the bottom layer uses natural cotton fibers to ensure good breathability and comfort of the material.
The preparation of nano TPU coatings uses a combination of solution impregnation and plasma treatment. First, TPU nanoparticles with a particle size range of 20-50 nm were dispersed in an organic solvent to form a stable nanodispersion liquid. Then, the dispersion liquid is uniformly coated on the surface of the substrate by spraying or rolling, and curing cross-linking reaction is carried out at a certain temperature to form a nanocoated layer with a three-dimensional network structure. The presence of this nano-scale TPU particle not only increases the roughness of the material surface, but also significantly improves theMaterial wear resistance and tear resistance strength.
In order to further optimize material performance, the researchers also introduced functional nanofillers such as silica (SiO2), alumina (Al2O3), etc. into the TPU coating. These nanofillers form a composite system with the TPU matrix through physical blending or in-situ polymerization, which can effectively improve the hardness, heat resistance and chemical stability of the material. Studies have shown that when the addition amount of nanofiller is controlled at 3-5 wt%, good comprehensive performance can be obtained [1].
In addition, the surface of the material has been treated with special plasma to improve its wettability and adhesion. Plasma treatment can generate a large number of active functional groups on the surface of the material, promoting chemical bonding between the nanocoat and the substrate, thereby improving the durability and stability of the coating. Experimental data show that the coating adhesion of samples treated with plasma can be increased by about 40%, and can still maintain good anti-slip performance after repeated friction [2].

Material performance test and data comparison analysis
In order to comprehensively evaluate the performance of the inter-cotton composite TPU anti-slip fabric, we conducted systematic testing and data analysis. The following table summarizes the key performance parameters of the material and compares them with traditional anti-slip materials:
| Performance metrics | Unit | Fang cotton composite TPU anti-slip fabric | Traditional rubber anti-slip fabric | Traditional PVC anti-slip fabric |
|---|---|---|---|---|
| Static friction coefficient | – | ≥1.2 | 0.8-1.0 | 0.7-0.9 |
| Kinetic friction coefficient | – | ≥1.0 | 0.6-0.8 | 0.5-0.7 |
| Abrasion resistance | mm³ | ≤20 | 50-70 | 60-80 |
| Tear resistance | N/mm | ≥30 | 20-25 | 15-20 |
| Heat resistance | °C | -40 to +120 | -20 to +80 | -10 to +60 |
| Moisture permeability | g/m²·24h | ≥5000 | 2000-3000 | 1000-2000 |
From the above data, it can be seen that the inter-cotton composite TPU anti-slip fabric shows obvious advantages in multiple key performance indicators. Especially in terms of friction coefficient, its static friction coefficient and dynamic friction coefficient are 20%-50% higher than traditional materials respectively, which is mainly due to the microscopic rough structure and strong adsorption force provided by nano TPU coatings. The wear resistance test results show that the wear amount of this material is only about 1/3 of that of traditional materials, showing excellent durability.
In terms of mechanical properties, the significant improvement in tear resistance strength is attributed to the enhancement of nanofillers and the good toughness of the TPU matrix. Heat resistance tests show that the material can maintain stable performance over a wider temperature range and is suitable for a variety of complex environments. In addition, the moisture permeability of up to 5000g/m²·24h ensures good comfort in the use of the material, especially suitable for the production of professional sports equipment and protective supplies.
It is worth noting that the material has also passed strict environmental certification, complies with the requirements of REACH regulations, and does not contain any harmful substances. Its production process adopts green chemical technology, and its energy consumption is reduced by about 30% compared with traditional processes, reflecting the concept of sustainable development. These excellent performance indicators make the inter-cotton composite TPU anti-slip fabric show strong competitiveness in high-end applications.
Specific application methods of nanotechnology in inter-cotton composite TPU anti-slip fabric
The application of nanotechnology in intercotch composite TPU anti-slip fabrics is mainly reflected in three core links: selection and modification of nanoparticles, construction methods of nanocoatings, and functional surface treatment. First, in the selection of nanoparticles, the research team focused on developing three types of nanomaterials: hard reinforced nanoparticles (such as SiO2 and TiO2)., flexible toughened nanoparticles (such as graphene quantum dots) and functional nanoparticles (such as silver nanoparticles). These nanoparticles are modified by surface modification technology, so that they can not only form good compatibility with the TPU matrix, but also exert their unique functional characteristics [1].
In terms of nanocoating construction, an innovative layer-by-Layer Self-Assembly Technique is adopted. This technology achieves precise regulation of coating thickness and structure by controlling the deposition order and number of layers of nanoparticles on the substrate surface. The specific operation process includes the following steps: firstly, plasma pretreat the surface of the substrate to form an active surface rich in hydroxyl and carboxyl groups; then alternately deposit positive and negative charge nanoparticle layers, and use electrostatic interaction to achieve Stacking layer by layer; then cross-linking reaction is initiated by ultraviolet light irradiation to form a firm and stable nanocoating [2].
In order to further improve the functionality of the material, a variety of surface treatment technologies are also adopted. This includes superhydrophobic surface construction technology, which introduces fluorosilane compounds into the TPU coating to present a microstructure similar to lotus leaves on the surface, and has excellent self-cleaning ability; antibacterial functionalization technology, loading silver nanoparticles Or quaternary ammonium antibacterial agents, which impart long-term antibacterial properties to the material; and conductive functional processing technology, doping conductive nanomaterials (such as carbon nanotubes, graphene), makes the material have certain conductivity and can be used for smart wear.
