Study Notes
Permanent Crease and Wrinkle-Free Treatments
- Suitable for 100% cotton garments like trousers and skirts; DMDHEU is commonly used to achieve permanent pleats.
- The chemical treatment needs curing before any wet processing is applied; garments are pressed at 150°C.
- Heat treatment is followed for 5 minutes, and optional washing can occur to remove stains.
- Robotic spray systems (e.g., Picasso SS330) are used for uniform chemical application on cotton, linen, or viscose.
- Garments undergo drying, hot pressing, and rinsing to eliminate unreacted resin.
- Surface finishes such as stain release modifiers help reduce pilling by altering the fiber’s surface protein.
Garment Dyeing
- Garment dyeing occurs after the manufacturing of garments, allowing cost-effective and trendy production.
- Common fabrics include cotton and blends with textiles like wool, nylon, and silk.
- Paddle machines and rotary drums are used for dyeing; paddle machines utilize high liquor ratios while rotary drums gently handle garments.
- Reactive dyes pose challenges in color fastness, particularly under wet conditions if not completely rinsed.
- After-treated direct dyes are traditionally used for both pale and dark shades; treatments can enhance soil-release properties and UV protection.
- Wet processing can involve additional finishes for antimicrobial properties and comfort, followed by drying processes.
Knitwear Finishing
- Special processing in knitwear is crucial for quality enhancement.
- Knitwear includes various fibers and blends, often requiring gentle handling to avoid damage during finishing.
- Stone tumbling is used in denim processing to create aesthetic effects and does not involve chemicals.
- Micro-sanding techniques include sandblasting, machine sanding, and hand sanding, with sandblasting being the most common.
- Recent advancements include laser technology for creating patterns on denim, improving efficiency while minimizing fabric damage.
Pressing Techniques and Equipment
- Pressing is essential for removing creases and presenting garments attractively for sale.
- Proper garment presentation affects consumer perception and brand recognition; poorly pressed items can decrease retail value.
- High-performance machines for shirt finishing include the Veit 8326 finisher and the Veit 8900 press, designed for optimal hem and sleeve positioning.
- The UADD B58 jacket press utilizes micro-processor control for precise pressure regulation and production monitoring.
- Household pressing is commonly done with electric irons, supported by pressing tables that may include vacuum features for stability during drying.
- Steam presses enhance efficiency and improve shape retention during the garment finishing process.
