Study Notes
Knitwear Overview
- Knitwear has gained a significant global market share due to casual dress trends and the versatility of modern knitting machinery.
- Knitting is a versatile textile method creating intermeshing loops from yarn.
- Historically, loop formation included knotting or spool-and-pin methods, but modern fashion knitwear (weft knitting) primarily uses hand- or machine-based needle technologies.
- Hand knitting, dating back to the 15th century, is a skilled craft, while modern knitwear is produced by sophisticated computer-controlled machinery.
- William Lee's invention of the stocking frame in 1589 marked a key technological milestone.
- Two distinct knitting technologies exist (warp and weft) producing diverse fabrics for different applications.
- Knitted fabrics are generally less stable, more flexible, and have better drape than woven counterparts.
- Recent trends toward casual dress have significantly increased knitwear's popularity.
Loop Formation Process
- Mechanical loop formation differs significantly from hand knitting's complex wrist and finger movements.
- Each loop requires a specific needle, the type varying by machine.
- Loop formation involves six stages.
- Stage 1: Needle at rest position.
- Stage 2: Needle moves to the knit position.
- Stage 3: New yarn inserted into the hook.
- Stage 4: Old loop slips under latch, forcing it to close.
- Stage 5: Old loop knocks over.
- Stage 6: Takedown force completes the cycle, returning the needle to rest position.
- Yarns used for knitted fabrics have less twist compared to woven fabrics.
Knitting Terminology
- Stitches (wales) are counted horizontally, and rows (courses) are counted vertically.
- "Stitch" in industrial knitting terms refers to the type of stitch (knit, float, tuck), not the loop.
- Fabric weight varies from fine gauge (lightweight) to chunky gauge (heavyweight).
- Gauge represents needle count per unit length for needle bed.
Weft-Knitted Structures
- Most high-street knitwear is made of weft-knitted fabric.
- Weft knitting is versatile, creating a variety of structures with patterns.
- Basic weft-knitted structures include plain, rib, and purl.
- Plain: Identical looping pattern, differing appearances front and back; unstable edges.
- Rib: Face & reverse loops in the same course; balanced rib looks the same on both sides, while unbalanced ribs have a defined "face" side; highly stable edges with good elongation; thicker in collapsed state.
- Purl: Decorative structure; identical stitches alternating front/back, producing a ripple effect, good for infant/child apparel; More expensive to produce.
Weft-Knitting Machines
- Three main types of weft-knitting machines: circular, fully fashioned, and flatbed.
- A new flatbed type emerged producing seamless garments
- Most productive method is the circular knitting machine forming continuous tubes.
- Single- and double-jersey fabrics used for T-shirts & sweatshirts are often made by circular technology
- Flatbed (or rib) machines are versatile handling ribs, complex structures, diverse patterning options, and panel shaping; currently faster than in the past.
- Complete garment knitting (seamless) machines knit entire garments in one stage, eliminating waste & seams, common in designer and high street brands.
Warp-Knitted Structures
- Warp knitted structures are made from intertwined loops with crossing yarns.
- Warp machines have needles across the machine width. Each needle has an individual yarn source/guide.
- All loops in a course are formed simultaneously.
- Warp fabrics are frequently continuous sheets from filament yarns; machinery ranges from small (scarf/crochet) to wide (industrial).
- Warp knit fabrics have properties similar to woven structures (stability) or more extensibility.
- Major types are tricot & raschel machines.
- Tricot machines produce plain-type fabrics (e.g. lingerie, sportswear).
- Raschel machines produce openworks, laces, fancywork, pile fabrics, with less stretching.
Knitting Developments
- Significant technological advancements since William Lee's invention.
- Refinements include improved mechanical action for finer fabrics, alternative structure development, automated weft and warp machines.
- Introduction of computerized mechanisms, variable stroke knitting, and complete garment machines.
- Innovations resulted in sophisticated machinery, influencing design (e.g., skinny ribs).
- Computer-controlled systems are enabling production of complex patterns and shaped panels.
Quality Control
- Knitting fabric quality is influenced by factors like stitch type, yarn, fiber, and delivery friction.
- Loop length (or stitch length) measurement, essential for quality, is measured across defined numbers of stitches.
- Stich density (wales and courses/cm/in) is another key control point for ensuring accurate garment dimensions and maintaining consistent quality.
- Fabric samples are unreeved and measured using tools like HATRA testers and cross-referenced against machine reported data, to ensure consistent quality of yarn delivery.
Case Study/Design Considerations
- Knitted garments increasingly important for fashion reasons e.g., elastic recovery, drape, easy-care, thermal insulation, formability and softness.
- Design considerations for clothing should incorporate user requirements (warmth, comfort, and care) and fabric properties.
- Material choices (e.g., fibers like acrylic or polyester) impact final fabric quality and cost in relation to garment's intended use.
Future Trends
- Knitwear's continued prominence is predicted, with advancements in machinery supporting pattern and shape generation.
- Globalisation's influence on the industry is substantial, including low-cost labor opportunities.
- Future knitwear will combine advanced materials with sophisticated technology for innovative designs.
- Opportunities exist for computer-aided design (CAD) and computer-aided manufacturing (CAM) to improve garment simulations and customer experiences.
- Customisation and on-demand garment production will become more common.
Project Ideas
- Project 1: Observation of knitwear collections in stores.
- Project 2: Knitwear weight categorization.
- Project 3: Calculation of stitch density.
- Project 4: Evaluation of garments considering fitness for purpose/user requirements and materials options.
Revision Questions
- These questions cover the materials presented, relating to knitwear technologies and design principles.
