TPU-PDMS-TMS Coating Enhances Protective Fabric Comfort and Performance

A novel coating technology using TPU-PDMS-TMS on polycotton fabrics significantly improves liquid repellency and thermal resistance while maintaining acceptable comfort levels.

Polymers · 2017

Key Findings

01Achieved high hydrophobic surface with a water contact angle of 142°.
02Demonstrated durability against laundering and crocking cycles.
03Exhibited excellent long-term repellency against oils, liquids, and chemicals.
04Modified air and water vapor permeability, impacting moisture management.
05Enhanced thermal resistance of the fabric.

Application

Design takeaway

How to apply

When designing workwear or outdoor gear, consider using durable, repellent coatings. Test the coated materials for breathability and moisture vapor transmission rates to ensure adequate comfort for the intended use and duration.

Project actions

01When researching materials for protective gear, look for coatings that offer multiple resistances (water, oil, chemical).
02Always consider the 'wearability' aspects: breathability, moisture management, and flexibility, alongside protection.

Method & Evidence

AimHow can a TPU-PDMS-TMS coating applied to polycotton fabrics enhance protective properties without compromising user comfort?

MethodExperimental research and material characterization

ProcedurePolycotton fabrics were coated using a padding-knife coating-padding-curing technique with a TPU-PDMS-TMS formulation. The coated fabrics were then subjected to various characterizations, including contact angle measurements, laundering and crocking durability tests, and assessments of air and water vapor permeability, moisture management, and thermal resistance.

ContextProtective clothing and functional textiles (e.g., military, mining, outdoor gear)

Variables

IVApplication of TPU-PDMS-TMS coating.

DVHydrophobicity (water contact angle), oleophobicity, durability (laundering/crocking resistance), air permeability, water vapor permeability, thermal resistance.

CVFabric type (polycotton 80/20), coating application method (padding-knife coating-padding-curing).

Strengths & Limitations

Strengths

+Developed a novel, fluorine-free coating.
+Demonstrated multi-functional protective properties (hydrophobic, oleophobic, chemical repellent).
+Assessed durability and comfort-related properties (permeability, thermal resistance).

Limitations

The study did not extensively test the long-term effects of the coating on fabric flexibility or the subjective comfort experienced by wearers.

Reliability & validity

The study uses standard material characterization techniques (contact angle, permeability tests) which lend reliability. Validity is supported by testing multiple properties and durability, though subjective comfort measures are less emphasized.

Think critically

How might the changes in air and water vapor permeability, as noted in this study, affect the wearer's thermal comfort and perceived 'feel' of the fabric during prolonged use in different environmental conditions?

Design Principles

"Functional coatings can enhance material performance, but their impact on human comfort factors must be thoroughly evaluated and managed."

For designers of protective clothing and functional textiles, this research offers a method to balance robust protection with user comfort. Understanding how material coatings affect properties like breathability and moisture management is crucial for creating garments that are both effective and wearable in demanding environments.

What This Means for Your Design

This study shows how a special coating can make fabrics really good at repelling water and oil, making them useful for protective clothing, and it also makes them warmer. It's important to check how this coating affects how breathable the fabric is, so people wearing it stay comfortable.

How to use in your project

1.Use this research to justify the selection of advanced materials or coatings for a design project focused on protective apparel.
2.Refer to the findings on contact angles and durability to support claims about material performance.

Paragraph starter

Research by Moiz, Padhye, and Wang (2017) developed a TPU-PDMS-TMS coating for polycotton fabrics that significantly enhanced hydrophobic and oleophobic properties, achieving a water contact angle of 142° and demonstrating durability through laundering and crocking. This advancement is crucial for functional textiles, offering improved protection while also enhancing thermal resistance, though it necessitates careful consideration of its impact on air and water vapor permeability for optimal user comfort.
