How to Solve Problems When Printing Knitted Fabrics

Printing on knitted fabrics can present various challenges, from dealing with cloth feather to maintaining stable gram weight. In this article, we, as experts in circular knitting machines, aim to address some common issues encountered during the printing process and provide effective solutions to overcome these challenges.

Problem 1: Cloth Feather Management

One common issue in printing knitted fabrics is dealing with cloth feather, which can obstruct the pattern gridding and result in blockages during the pre-treatment process. To address this:

• Manufacturers should conduct thorough inspections of fabrics to identify low-quality ones and handle them promptly.
• Implement effective pre-treatment processes by adjusting settings and increasing washing time to minimize feather occurrence.
• Utilize knitting machines equipped with vacuum cleaners and apply sticky nets on printing machines to capture excess feather.

Problem 2: Hole Formation in Finished Products

Holes in finished products can arise due to various factors, including inherent holes in original cloths, machine damage, and human error. To mitigate this issue:

• Conduct meticulous inspections of original cloth to identify and address any existing holes before further processing.
• Opt for fabrics with smooth textures and superior durability to minimize the risk of hole formation.
• Enhance operator responsibility by ensuring machines are clean and free of sharp items, and maintain consistent machine speeds.

Problem 3: Maintaining Stable Gram Weight

Stable gram weight is crucial for ensuring the quality of knitted fabrics and meeting customer expectations. To achieve this:

• Thoroughly assess the quality of original cloth to identify any deviations from the desired gram weight.
• Address any discrepancies in gram weight by optimizing equipment settings and refining techniques.
• Select appropriate equipment and auxiliary dyes, and tailor techniques based on fabric characteristics.
• Consider incorporating additives such as urea and water to boost gram weight and address any deficiencies.

Problem 4: Anti-Staining Measures

Knitted fabrics, lacking mercerization, are prone to staining during washing, necessitating effective anti-staining measures:

• Choose soap lotions with superior anti-staining properties to minimize contamination.
• Ensure thorough removal of paste residue to prevent tough texture and reduce the need for softening agents, thus lowering costs.
• Exercise caution during processing to prevent residual colors, which can compromise product quality.

In conclusion, by implementing these solutions, manufacturers can effectively address common challenges encountered when printing on knitted fabrics, ensuring high-quality results and customer satisfaction.
