Knitted Garment Construction Techniques

Knitted Garment Cutting

• Knitted fabrics are cut using specialized patterns and techniques, differing from woven fabrics due to the inherent stretch and drape of knits.
• Pattern layouts are crucial for minimizing fabric waste and optimizing yarn use. Methods vary based on the type of knitting stitch, the machine, and the end product.
• Considerations include the stretch and recovery properties of the specific yarn and knit.
• Accurate pattern marking ensures consistent fabric positioning during cutting.
• Fabric cutting tools include rotary cutters, specialized blades/shears for preventing damage to knits. Automated cutting tools are used for high-volume production.

Knitted Garment Stitching

• Stitching methods differ for knit fabrics versus woven fabrics, accommodating the elongation/recovery of knits to prevent distortion.
• Stitching techniques are vital for stitch strength and to prevent fabric ripping/snagging, while accounting for knit stretch.
• Specialized needles and thread types are necessary for knits, differing from those used in woven garments.
• Seams should be strategically placed to create smooth, even fabric joints.
• Seam allowances and stitch lengths must be adjusted for knits based on their properties compared to woven fabrics.
• Over-stitching is often applied to the raw edges of knit fabrics to prevent fraying and maintain garment shape.
• Specialized industrial sewing machines are often used for stitching knits, suitable for fabric feed, stitch type, and tension control.

Knitted Garment Quality Control

• Quality control checks are crucial throughout knit garment production, both pre- and post-production.
• Initial fabric inspection assesses yarn quality and material appearance (color, flaws).
• Dimensional accuracy and uniformity (length, width, circumference) are checked against prescribed standards for each garment.
• Stitching is inspected for evenness, strength, absence of puckers, and seam quality.
• Garment fit, drape, and appearance are evaluated, potentially involving modeling for fit confirmation.
• Checks during stitching can identify potential issues in production, while post-production checks evaluate sewing and handling flaws.
• Pre-production sampling and testing, and post-production tests are essential for maintaining quality standards, focusing on stretch/recovery properties.
• Garments must satisfy predetermined specifications and quality ratings.
• Identifying and rectifying garment defects is crucial for maintaining standards and customer satisfaction.
• Detailed record keeping of quality control procedures and results is key for process improvements.
• A comprehensive quality control system helps identify and fix flaws, problems, and irregularities in knit garment production. Feedback is vital for improving quality, production time, efficiency, and costs.
