I. Learning Objectives

  1. Master the core communication elements for addressing “excessive yarn breakage” in Polyester POY post-processing, ensuring information is transmitted clearly, completely, and without omission.

  2. Tailor communication focus and delivery based on the specific characteristics and responsibilities of the audience (operators, technicians, management, etc.).

  3. Improve cross-departmental collaboration efficiency by using precise communication to accelerate the analysis and resolution of breakage issues.

II. Target Audience

Personnel involved in Polyester POY production and post-processing (including operators, technicians, maintenance staff, management, and sales representatives).

III. Key Focus and Difficulties

  • Key Focus: Essential information that must be covered during communication (breakage phenomena, specific requests, etc.); differentiated communication techniques tailored to different roles.

  • Difficulties: Moving beyond vague descriptions like “too many breakages” to providing precise, actionable data; ensuring that communication outcomes lead to tangible improvement actions.

IV. Communication Core

1. Problem Context

The specific impact of excessive yarn breakage in Polyester POY post-processing (texturing): Directly leads to decreased production efficiency, increased raw material waste, fluctuations in product quality, and increased labor intensity for employees.

2. Core Communication Points

  • ① Detailed Description of the Breakage Phenomenon

    • Time: The specific timeframe when the breakage began (e.g., “abnormal since startup,” “breakage increased after changing bobbins at 8:00 AM today,” “high breakage over the past 3 days”) and the frequency (e.g., “5 breaks per hour,” “3 consecutive breaks on the same spindle of machine No. 3”).

    • Location: The exact process segment where the break occurred (e.g., feeding zone, stretching zone); the specific position on the POY bobbin (e.g., outer layers, middle layers, inner layers, or during tail-end processing). Note any visible defects (e.g., poor tail silk, heavy hairiness, knots, or damaged paper tubes).

    • Characteristics: The morphology of the break (e.g., breaks under high/low tension, or caused by tension CV fluctuations).

    • Scope: The affected machines (a single machine vs. all machines) and critical POY data such as lot number, specifications, production date, and spindle number (e.g., recurring breaks on specific spindle positions for a specific POY lot).

  • ② Communication Objectives and Requests

    • Clearly express the support required from the other party (e.g., “require on-site technical inspection of equipment and process parameters,” “need quality improvement,” “require coordination to switch POY lots for trial testing,” or “request for replacement/return”).

3. Communication Techniques by Audience

  • With Operators: Focus on specific details using industry-standard terminology (e.g., “How many breaks occurred on the machine you operate, and did you notice any abnormalities with the POY?”). Encourage timely logging of breaks and observations. Be mindful of spindle configurations (e.g., 240, 288, 312, 360 spindles).

  • With Technicians: Focus on technical analysis (e.g., “Is the maintenance cycle due? What was the previous product type produced? Do the ceramic parts need replacement? Does the process require optimization?”).

  • With Management: State the business impact (e.g., “Employee feedback regarding the current breakage level, the increase in second-grade products, the drop in AA grade rates”). Clearly outline actions taken and resources required (e.g., “Is an emergency stock transfer required for testing? Do we need to apply for a dedicated trial run on a single machine? Should we swap to a different production date for tracking?”).

4. Post-Communication Actions and Documentation

  • Emphasize “Closed-loop Communication”: After communication, the responsible person must record the key points, define the specific measures taken, and set a timeline for follow-up to verify improvements.

By completing this training, relevant personnel will be equipped to communicate “efficiently and professionally” when facing excessive POY post-processing breakage, laying a solid foundation for rapid problem resolution.
