Environmental Performance Analysis

Lycra composite TPU fabric has outstanding performance in environmental protection performance, mainly reflected in three key links: raw material selection, production process and life cycle management. First, the material uses recyclable TPU raw materials, which reduces carbon emissions by about 40% compared to traditional PVC materials (according to research data from the European Plastics Converters Association). The TPU material itself has good biodegradability and can be decomposed into carbon dioxide and water under industrial compost conditions after special treatment, which complies with the requirements of the EU REACH regulations.

In terms of production process, Leica cloth composite TPU fabric adopts advanced solvent-free composite technology. Compared with the traditional wet composite process, this process eliminates the use of organic solvents and greatly reduces VOC (volatile organic compounds) emissions. According to a research report published by Journal of Cleaner Production, solvent-free composite technology can reduce the release of volatile organic compounds by more than 95%, while saving energy consumption by 30%. In addition, this process can effectively control the TPU film thickness to ensure that the material achieves the expected performance while saving resources to the maximum extent.

From the whole lifeFrom a cyclical perspective, Leica composite TPU fabric exhibits significant environmentally friendly characteristics. It has strong durability and long service life, which can effectively reduce waste caused by frequent replacement. After the product is scrapped, it can be recycled and reused through physical or chemical methods to form a complete circular economy chain. According to statistics from the journal Environmental Science & Technology, products made of such recyclable materials have a total environmental impact of about 35% lower than traditional materials.

It is worth noting that the material has also passed a number of international environmental certifications, including Oeko-Tex Standard 100, bluesign® system, etc., proving its outstanding performance in the control of hazardous substances and environmental protection. These certifications not only ensure the safety of the product, but also provide consumers with reliable environmental protection guarantees.

Comfort technology analysis

Lycra composite TPU fabrics show multiple technical advantages in terms of comfort, and their core principle lies in the unique three-layer composite structural design. The outer fabric is made of high-volume lycra fiber, which gives the fabric excellent elasticity and fit, effectively dispersing pressure points and reducing the discomfort caused by long-term rides. According to the experimental data of Journal of Textile Research, the tensile recovery rate of this fabric is as high as 98%, far exceeding the 75%-80% range of ordinary knitted fabrics, which makes the seat cover perfectly fit the human body curve and provide more comfortable support. Experience.

In terms of temperature regulation, the TPU intermediate layer plays a key role. Its microporous structure design achieves ideal breathable and moisture permeability, with the water vapor permeability per square meter per hour reaching 2000-3000g/m², ensuring the internal environment is dry and comfortable. At the same time, the TPU film has good heat conduction characteristics, can quickly disperse human heat and maintain appropriate body surface temperature. A study published by Textile Research Journal shows that the material has a thermal and humidity comfort index (HUMI) of more than 85 points, which is better than most child seat fabrics on the market.

Touch comfort is an important indicator for measuring fabric quality. Lycra composite TPU fabrics use surface treatment technology to form a soft and delicate feel, with a friction coefficient as low as 0.25 (static friction), which is significantly lower than the range of 0.4-0.6 of ordinary fabrics. This feature not only improves children’s comfort while riding, but also effectively prevents wear of clothes. In addition, the fabric surface has been treated with antistatic treatment to avoid the discomfort caused by static accumulation.

The material performs excellently in terms of dimensional stability. The shrinkage rate in the meridian and latitude directions is controlled within 2%, ensuring that it can maintain a good shape after long-term use. This stable dimensional feature is especially important for child safety seat covers, as any deformation can affect the functionality and safety of the seat. According to InternationalTest results from Journal of Clothing Science and Technology, the fabric still maintains its initial shape and performance after repeated 50 times, showing excellent durability.

Detailed explanation of technical parameters

The core technical parameters of Leica composite TPU fabric cover multiple key dimensions, and the specific values ​​are shown in the table below:

From the mechanical properties, the tensile strength of this fabric is significantly higher than that of ordinary textiles (usually 200-300N/cm), which is due to the synergy between TPU film and Leica fibers. The elongation index reflects the elastic recovery ability of the material and can maintain stable shape while ensuring comfort. The excellent performance of water vapor transmission and waterproofing grade reflects the exquisite design of TPU film in functional balance.

In terms of functional parameters, the breathability index reaches the ideal range, ensuring good air circulation. Optimization of the surface friction coefficient not only improves tactile comfort, but also helps reduce discomfort during relative movement. Thermal conductivity coefficientThis shows that the material can effectively regulate heat transfer and adapt to different ambient temperatures.

The wear resistance test results show that the fabric can withstand high strength use and meet the special needs of child safety seat covers. Aging resistance test proves the stability of the material under ultraviolet irradiation and extends the service life of the product. Antibacterial performance testing verifies its hygiene and safety, which is particularly important for children’s products. Easily cleansing evaluation shows that the fabric has good stain removal effect, simplifying daily maintenance.
