Consumer Expectations

  • Consumers expect garments to have functional properties that align with specific wear conditions.

  • Garments are not only expected to offer comfort, modesty, and style but must also provide functionalities such as:

    • Anti-wrinkling

    • Breathability

    • Waterproofing

    • UV protection

    • Psychological comfort

  • Different materials require tailored treatments to meet these performance requirements, often involving compromises in properties.

Garment Functionality

  • Garment functionality can be improved at various stages:

    • Fibre stage

    • Yarn stage

    • Fabric stage

    • Garment stage

  • Compromises may need to be made based on cost, health, and environmental factors.

Factors Affecting Garment Function

  • Garments are complex, resulting from various interactions of:

    • Fibre, yarn, and fabric structures

    • Mechanical and chemical finishing procedures

  • Choices depend on desired characteristics:

    • High performance may prioritize strength over comfort (e.g., polyester for durability).

    • Softness may lead to using natural fibres like cotton, linen, or cashmere.

Improving Fabric Handle and Tailorability

  • Fabric handle refers to the tactile quality and is assessed based on:

    • Surface friction

    • Bending stiffness

    • Compression

    • Thickness

  • Tailorability relates to how well a fabric can be fabricated and worn. Factors include:

    • Fibre Properties

      • Diameter and cross-sectional shape affect stiffness and handle.

      • Finer fibres generally yield softer fabrics (e.g., cashmere).

      • Coarser fibres can create harsh textures (e.g., wool).

    • Yarn Properties

      • Yarn structure and twist influence fabric handle and making-up properties.

    • Fabric Properties

      • Tightly woven fabrics often result in stiffer handles, impacting wear performance.

Reducing Wrinkling

  • Wrinkles are defined as unwanted residual deformations. Two types occur:

    • Pressure wrinkles (sharp creases during static pressure)

    • Movement wrinkles (rounded creases during movement)

  • Key factors affecting wrinkling include:

    • Temperature and moisture content

    • Duration and type of deformation

  • Improving wrinkle recovery can be done at:

    • Micro level: Changing the fibre structure.

    • Macro level: Adjusting fabric or garment design to minimize deformation.

Pilling Reduction

  • Pilling refers to the formation of small balls of entangled fibers on the fabric surface.

  • Factors affecting pilling:

    • Fibre length and diameter

    • Inter-fibre friction

    • Fabric structure

  • Treatments like singeing and shearing can help reduce pilling propensity.

Bagging Prevention

  • Bagging is permanent deformation in fabrics caused by wear.

  • Influenced by:

    • Elastic and viscoelastic properties of fibres

    • Check with yarn and fabric construction

    • Garment fit and design

  • Key properties to resist bagging include:

    • Good recovery from deformation

    • Appropriate tension and stretch in yarns.

Improving Drape

  • Drape refers to how a fabric hangs and folds under its own weight.

  • Influencing factors include:

    • Fibre diameter and stiffness

    • Yarn properties and structure

    • Fabric finishing treatments.

Enhancing Durability

  • Durability includes the wear life of textiles and their appearance over time.

  • Important factors for durability:

    • Fibre strength, elongation, and recovery

    • Fabric structure and properties

  • Balancing durability with comfort and aesthetics is essential in garment design.

Research and Future Trends

  • Future trends may include multifunctional fabrics with:

    • UV protection

    • Self-cleaning and self-healing properties

    • Enhanced aesthetic and performance features.
