Detailed explanation of parameters of TPU composite milk silk fabric
TPU composite milk silk fabrics occupy an important position in the high-end dress market due to their unique physical characteristics and functionality. The following is a detailed analysis of the main parameters of the fabric:
Surface finish
The surface finish of the TPU composite milk silk fabric is extremely high, presenting a natural and soft sheen, thanks to the smooth texture of its TPU layer and the delicate structure of the milk protein fibers. This luster not only enhances the visual effect, but also effectively reduces light reflections, so that the fabric can maintain a consistent aesthetic under different light sources.
Elastic Modulus
| parameter name | Numerical Range (MPa) | Description |
|---|---|---|
| Tension elastic modulus | 20-40 | The fabric has strong elastic recovery ability when stretching, and is suitable for dress designs that require close-fitting tailoring. |
| Compression elastic modulus | 15-30 | It can still maintain the shape and increase the comfort of wearing in the compressed state. |
The elastic modulus is an important indicator to measure the deformation ability of a material under external force. The TPU composite milk silk fabric has a high elastic modulus, which means it can quickly return to its original state after being stretched or compressed, which is especially important for dresses that require close-fitting cuts.
Density
| parameter name | Value (g/cm³) | Description |
|---|---|---|
| Fabric density | 1.1-1.3 | The lower density makes the fabric lighter and increases the comfort of wearing. |
Density refers to unit volumeThe quality of the substance, the low density properties of TPU composite milk silk fabrics make it keep it lightweight while ensuring strength, making it ideal for high-end gowns.
Fiber Diameter
| parameter name | Numerical range (μm) | Description |
|---|---|---|
| Average fiber diameter | 10-15 | The delicate fiber diameter gives the fabric a soft feel and excellent drape. |
Fiber diameter directly affects the softness and feel of the fabric. The fiber diameter of the TPU composite milk silk is small, so it is very soft to touch and has good drape, which is crucial for the styling of the dress.
Hymoscopicity
| parameter name | Value (%) | Description |
|---|---|---|
| Hydragonism | 8-12 | Can effectively absorb and emit moisture generated by the human body, keeping the wearer dry and comfortable. |
Hydroscope reflects the fabric’s ability to absorb and release moisture. The moisture absorption rate of TPU composite milk silk fabric is moderate, which can adjust the humidity of the wear environment to a certain extent, thereby improving the comfort of wearing.
To sum up, the parameters of TPU composite milk silk fabric provide a solid foundation for its wide application in high-end dresses, and they perform well in terms of visual effects and actual wear experience.
Application of antistatic technology in TPU composite milk silk fabrics
The application of antistatic technology in TPU composite milk silk fabrics is a key technology, aiming to solve the static problems caused by friction, thereby improving the practicality and comfort of the fabric. Electrostatic phenomena usually occur in dry environments, and when two different materials rub against each other, electron transfer can lead to charge accumulation. For high-end dresses, static electricity not only affects the wearing experience, but may also destroy the appearance of the clothing. Therefore, the introduction of antistatic technology is particularly important.
Basic Principles of Antistatic Technology
The core of antistatic technology is to reduce or eliminate the generation and accumulation of static electricity. Specifically, it can be achieved through the following two methods: one is to increase the conductivity of the fabric so that the charge can dissipate quickly; the other is to reduce the formation conditions of static electricity by improving the moisture absorption performance of the fabric. TPU composite milk silk fabrics are added to the production process by adding conductive fibers or coatings.The antistatic properties are significantly improved.
Specific implementation method
-
Conductive fiber blend
Embedding a small amount of conductive fibers (such as carbon fiber or metal fiber) into the fiber structure of the TPU composite milk wire can effectively form a conductive network and help the charge to quickly conduct it to the ground. This method will not change the overall appearance of the fabric, but also significantly improves the anti-static effect. -
Antistatic coating treatment
By applying a thin layer of antistatic agents (such as quaternary ammonium compounds or silicone substances) to the surface of the fabric, its surface resistivity can be significantly reduced. This type of coating not only prevents static electricity accumulation, but also improves the durability and careability of the fabric. -
Improving hygroscopic performance
The TPU composite milk silk itself has a certain hygroscopicity, but in order to further enhance its antistatic ability, the moisture absorption and sweating function of the fabric can be optimized by adjusting the proportion of milk protein fibers or adding hydrophilic additives. This not only helps reduce the generation of static electricity, but also improves the comfort of wearing.
Practical Effect Evaluation
The following is a comparison of the effects of several common antistatic technologies:
| Technical Type | Antistatic effect score (out of 10 points) | Feature Description |
|---|---|---|
| Conductive fiber blend | 9 | provides a fast charge conduction path, with significant anti-static effect, but high cost. |
| Antistatic coating treatment | 8 | Easy to implement and low cost, but the coating may wear after long-term use and requires regular maintenance. |
| Improving hygroscopic performance | 7 | It is mainly aimed at environmental humidity regulation and has certain auxiliary effects on anti-static electricity, but the effect of using alone is limited. |
From the practical application point of view, conductive fiber blending technology is considered to be one of the effective solutions at present, especially suitable for high-end dresses and other scenarios with high quality requirements. However, considering the cost and process complexity, antistatic coating treatment is also a cost-effective option.
Foreign literature support
According to the American Textile Association,A study by ATA, conductive fiber blending technology can reduce the surface resistivity of TPU composite milk silk fabrics to below 10^6 Ω, which is much lower than the 10^9 Ω level of ordinary fabrics, significantly reducing the possibility of electrostatic accumulation. . In addition, a paper published by the German Textile Research Center (GTRC) pointed out that by optimizing hygroscopic properties, the peak of the electrostatic voltage can be reduced by about 30%, providing additional guarantees for the antistatic properties of the fabric.
In short, the application of antistatic technology in TPU composite milk silk fabrics not only solves the static problem, but also further improves the functionality and durability of the fabric, providing more possibilities for the design and production of high-end dresses.
