RFP Title


Development  Partner for Testing Instrument to Measure Yarn Tension
RFP Description

NineSigma, representing a multibillion-dollar manufacturer in clothing industry, seeks a development partner for a testing instrument to measure yarn tension of weaving machinery. Specifically, the client aims at tension measurement of every single piece of yarns disposed at a density of 6 pieces/cm. Proposals for a technology that has not been applied to textiles and will require additional development are also welcome.

The client’s goal is to develop a testing instrument; however, it is also considering introducing the technology to the production line, depending on the circumstances.

Key Success Criteria

Client’s Current Situation

  • In the client’s weaving machinery, 480 yarns per 80 cm (density of 6 yarns/cm) are aligned in parallel.
    • Yarn material: PET
    • Thickness: Approx. 0.3 mm
    • Yarn feeding speed: Approx. 1-2 cm/s
  • As illustrated in Figure 1, the current tension measuring instrument of 1 cm width can measure 1 yarn, which means only 1 in 6 yarns aligned at density of 6 yarns/cm can be measured. However, all yarns should be measured ideally.

Figure 1. Current tension measurement

(measurement of 1 yarn in 1 cm)

Development Goal

  • The tension of ALL yarns aligned at a density of 6 yarns/cm, as described above, should be measured at all times.
  • Measurement range of tension: 02 N
  • Time resolution: 100 Hz or more
  • Continuous measurement time: 12 hours or longer
  • Data recording method: To prevent the volume of measured data from being excessive, it is preferable that the instrument should be able to record data only for a few minutes before and after abnormal values are detected.

Anticipated Respondents

Anticipated organizations include, but are not limited to, the following:

  • Tension meter manufacturers
  • Corporations and universities specialized in the development of customized devices using sensors
  • Pressure sensor manufacturers
Possible Approaches

Possible Approaches

Possible approaches might include, but are not limited to:

  • Approach to align compact tension meters side by side in the same manner as now
  • Approach that enables detection for all yarns by installing the tension meters three-dimensionally
    • In this approach, measured values should remain the same even if the incident angle of yarns against the instrument changes.
  • Approach using a non-contact mechanism, such as light

Proposals for a technology that has not yet been applied to textiles and will require additional development are also welcome.


The client produces textiles using weaving machinery. For yarn floats that unexpectedly occur as defects in the production process, it seeks to determine the cause and take measures to solve the problem.

While striving to collect data of yarn tension before and after floats occur in order to determine the cause of such defects, the client has yet to find an instrument that can fulfill all of its required specifications, such as the number of yarns that can be simultaneously measured, instrument size, and data proceeding function. Thus, the client can conduct only limited activities to improve the current situation.

Therefore, the client has issued this open request to select a potential partner(s) from corporations and researchers with excellent technology outside their existing network.

The client aims to develop a testing instrument in this open request, and depending on the circumstances, is considering introducing the technology to the production line.


Items to be Submitted
Notes on Response

Proposal shall have clear points and should not include confidential information. Supplemental files may be submitted in addition to the proposal.


Response evaluation

The client will evaluate all responses with the following criteria.

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Realism of the proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences


Anticipated Project Process

After reviewing submitted proposals, the client possibly ask clarifying questions before selecting the most suitable candidates for collaboration. The client will select best candidates through evaluations. During the selection process, the client may execute NDA with selected respondents, seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreements with the selected respondents and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
