Analysis of performance advantages and limitations

Elastic knitted fabric composite PU silver coated fabric shows significant technical advantages in extreme environments, but also has certain limitations. The following is a detailed analysis from three aspects: physical properties, chemical properties and economics:

Physical performance advantages and limitations

The fabric has a prominent advantage in its excellent elastic recovery rate (≥95%), thanks to the combination of a unique double-layer knitted structure and high elastic fibers. However, this structure also brings about the problem of increased thickness, limiting its use in certain application scenarios where lightweight is extremely demanding. For example, according to Kumar et al. (2021), when applied to skydiving suits, the thickness of the fabric may cause an increase in air resistance by about 8%, affecting flight performance.

Another significant advantage is its waterproof and breathable performance (waterproof grade 10,000mm H₂O, moisture permeability ≥5,000g/m²/24h). This balance allows the fabric to remain dry and comfortable in humid environments. However, it should be noted that long-term exposure to high humidity environments may affect the stability of the PU coating. Experimental data show that in an environment with a relative humidity of more than 95% for more than 30 days, the waterproof performance of the coating will decrease by about 15%.

Chemical performance advantages and limitations

In terms of chemical properties, the fabric exhibits excellent acid and alkali resistance and UV resistance. The presence of silver coating not only gives the fabric a strong antibacterial ability (bacterial antibacterial rate ≥99.9%), but also effectively shields electromagnetic interference. However, the durability of the silver layer remains a challenge. According to Liu & Wang (2022), under repeated cleaning conditions, the thickness of the silver layer may be reduced by about 20%-30%, affecting its long-term antibacterial effect. In addition, although fabrics are well resistant to common chemicals, slight discoloration may occur in strong oxidant environments (such as chlorine-containing disinfectant concentration >5%).

Economic Advantages and Limitations

From an economic point of view, the initial investment cost of this fabric is high, mainly due to complex production processes and raw material selection. According to Industry Research ReporAccording to data from ts (2023), the unit production cost of this fabric is about 2.5 times that of ordinary protective fabrics. However, the overall cost-effectiveness is still competitive given its longer service life and lower maintenance costs. For example, in polar scientific research applications, although the procurement cost has increased by about 60%, the actual usage cost has been reduced by about 20% due to nearly doubled service life.

It is worth noting that the fabric is difficult to process and has strict requirements on production equipment and technology, which to a certain extent limits its large-scale promotion. At the same time, the high R&D investment has also kept the price high, limiting its application scope in the low-end market. Despite this, with the advancement of technological progress and the advancement of large-scale production, it is expected that its production costs will be reduced by about 30%-40% in the next few years, thereby further expanding the scope of market application.
