Explain whisker in dry process to garment productions?

Scratch in dry process in garment production refers to the technique of distressing or creating a worn-out look on the fabric using abrasive tools such as sandpaper, pumice stones, or wire brushes. This process is typically done after the garment has been sewn together and before it is washed or finished.

To create a scratch effect, the garment is placed on a flat surface and the abrasive tool is rubbed against the fabric in a specific pattern or direction to create scratches or abrasions. This technique is often used to give denim garments a vintage or distressed look, as well as to add texture and character to other types of fabrics.

Scratching can be done in various intensities and patterns to achieve different effects, from subtle fading to more dramatic distressing. It is important to carefully control the pressure and technique used during the scratching process to ensure a consistent and desired result.

Overall, scratching in dry process is a popular technique in garment production for adding a unique and worn-in look to garments, and can be customized to achieve different styles and finishes.

Scratch in Dry Process

In garment production, "scratch" refers to a defect that occurs during the dry processing stage, where garments undergo cutting, sewing, and finishing. It primarily affects woven fabrics and can manifest as:

- Snagging: When fibers are pulled or broken, creating small holes or tears.

Causes of Scratch

Scratch can be caused by several factors during dry processing:

- Poor Quality Fabric: Fabrics with weak fibers or loose weaves are more susceptible to snagging.
- Dull or Damaged Needles: Blunt or damaged needles can catch and break fabric fibers.
- Overfeeding: Feeding fabric too quickly into machines can put excessive tension on the fabric, leading to fiber breakage.
- Incorrect Thread Tension: Too-tight thread tension can pull fibers out of the fabric, creating snags.
- Poorly Adjusted Machines: Mishandled or improperly calibrated machines can exert excessive pressure on the fabric, causing damage.
- Operator Error: Careless handling of garments during cutting, sewing, or pressing can cause snags or scratches.

Consequences of Scratch

Scratch can compromise the garment's appearance and overall quality:

- Reduced Esthetics: Visible holes or tears can detract from the garment's aesthetic appeal.
- Weakened Structure: Snags can weaken the fabric structure, making it more prone to further damage.
- Rejections and Rework: Garments with scratches may be rejected by customers or require extensive rework, which incurs additional costs.

Prevention and Control

To prevent and control scratch in dry processing, garment manufacturers should implement the following measures:

- Use High-Quality Fabrics: Choose fabrics with strong fibers and tight weaves.
- Maintain Needle Sharpness: Regularly replace or sharpen needles to ensure proper stitching.
- Calibrate Machines Properly: Make sure all machines are adjusted to optimum settings for the specific fabric and garment type.
- Control Fabric Feeding: Feed fabric at a controlled rate to avoid excessive tension.
- Use Optimal Thread Tension: Adjust thread tension to minimize fiber breakage.
- Train Operators: Train operators on proper fabric handling techniques and machine operation.
- Inspect Garments Regularly: Conduct quality control inspections at various stages of dry processing to detect and address any potential scratches.
