Advanced Suit Materials (ASM) Custom Textile Development

Textile Vendor SOW

Objective

The vendor will work with NASA to prototype woven fabrics using yarns provided by NASA.

Weave pattern combinations will be developed in collaboration with NASA and down selected by NASA. Prototyping will take place at the vendor facility using best effort for successful outcomes approach.

Key SOW Assumptions

1. Changes to this SOW cannot be made unless mutually agreed upon and confirmed in writing between the Parties’ designated representatives. Any change to this SOW may require additional funds.

2. The vendor will invoice Sponsor, monthly, based on milestone status and accompanying deliverable, according to the timeline/templates as defined in the tasks in this SOW.

3. The project described in this SOW involves a degree of uncertainty as to the ultimate outcome. Parties understand that milestones and/or deliverables described below include several “down selection decisions” which may result in a “lessons learned requiring changes to the SOW” of subsequent tasks and/or may call for a re-scoping of the effort.

4. In the event the Sponsor requests revisiting a completed task or milestone and/or deliverable or decision point, the parties understand they will need to mutually agree on the scope of work, schedule, and additional budget.

5. NASA and the vendor will have weekly progress meeting discussing relevant machine, yarn or fabric critical learnings with images and or data/settings.

PowerPoint format is acceptable, with update to timeline and project success.

6. The vendor will keep one copy of samples produced.

Project Scope

The scope of this project is to create a suite of fabric designs with a goal of 8 and threshold of 3, uniquely different tightly woven textiles from COTS yarns, down-selected from NASA teams’ previous work. Additional weaving using new yarns derived from coating or co-extrusion methods. The final fabric goal is to have minimal particle and air permeability, allowing for maximum possible drape using high performance yarns. The project includes two phases. In Phase I, the vendor will work with uncoated yarn to produce fabric and in Phase II, the vendor will work with coated yarns to produce fabric. All tasks and milestones described below are contingent on prompt delivery of raw materials and feedback on decisions by the NASA team within the timeframe required.

Phase I Tasks

NASA will provide up to seven specific uncoated yarn types to the vendor. Variations in yarn such as twist and denier would result in different yarn types. NASA will be responsible for the down selection of the final yarn types.

Upon award, NASA will travel to the vendor for onsite “kick-off” meeting to review lessons learned from previous NASA projects, and to show legacy, COTS, developmental yarns and fabric samples in preparation for Task 1 activity.

Task 1 – Uncoated yarn evaluation for warping suitability (time dependent on NASA delivering yarns). Uncoated may refer to twisted, plied or other co-polymer yarn solution.

o Task 1.1 The vendor will assess weaving structures of double cloth, 2x2 twill, basketweave and crepe structures. NASA yarn types/sizes will reflect cover factor/fabric density outcomes; the vendor will consult with NASA to make adjustments to the weave patterns as needed to maintain scope. NASA will down select the weave patterns based on their requirements. Weave patterns may include a ¼” grid ripstop (diagonal rip stop is not feasible in this SOW).

o Task 1.2 Upon receiving uncoated yarns from NASA, the vendor will evaluate warp suitability by producing one “striped” warp that includes all the different yarn types. NASA will choose the best feasible warp/yarn combinations. the vendor will consult with NASA to make adjustments to the warp combinations.

o Task 1.3 The vendor will provide a brief report of the steps above including warping results and mitigation required during warping as well as weave pattern development and down selection process.

Task 1 Deliverable complete. Lessons Learned Review: proceed to Task 2 or rescope.

Task 2 – Suitability of weaving warp combinations with uncoated yarns.

o Task 2.1 The vendor will produce up to four warp combinations with a single end warper based on NASA choice of the best feasible warp/yarn combinations.

o Task 2.2 The vendor will weave up to a total of four fabrics down selected during Task 1. Each fabric has a deliverable goal of 10 meters and threshold of 6 meters. Successful weaves will be delivered.

o Task 2.3 The vendor will provide a report describing weaving results.

Machine settings, weaving diagrams, yarn preparation settings, tension basics. fabric weight, fabric thickness, fabric end count, and CAD design models if applicable.

Deliverable 2 complete. Lessons Learned Review: proceed to Task 3 or rescope.

Phase II Tasks The fabric samples to be attempted in this phase are to be woven with the same above yarns with an added coating. The successful and timely delivery of the fabrics is dependent on the timely delivery of the coated yarn to the vendor. NASA will provide up to seven specific coated yarn types to the vendor. Variations in coating would result in different yarn types. NASA will be responsible for the down selection of the final coated yarns.

Task 3 – Coated yarn evaluation for warping suitability (time dependent on NASA delivering coated yarns).

o Task 3.1 Upon receiving coated yarns from NASA, the vendor will evaluate warp suitability by producing one “striped” warp that includes all the different coated yarn types. NASA will choose the best feasible warp/yarn combinations. the vendor will consult with NASA to make adjustments to the warp combinations.

o Task 3.2 the vendor will provide a brief report of the steps above including warping results and mitigation required during warping as well as weave pattern development and down selection process.

o Deliverable 3 complete. Lessons Learned Review: proceed to Task 4 or rescope.

Task 4 – Suitability of weaving warp combinations with coated yarns.

o Task 4.1 the vendor will produce up to four warp combinations with a single end warper based on NASA choice of the best feasible warp/coated yarn combinations.

o Task 4.2 the vendor will weave up to a total of four fabrics down selected during Task 1 and/or 2. Each fabric has a deliverable goal of 10 meters and threshold of 6 meters. Successful weaves will be delivered.

o Task 4.3 the vendor will provide a report describing weaving results and all relevant weaving information. Machine settings, weaving diagrams, yarn preparation settings, tension basics. fabric weight, fabric thickness, fabric end count, and CAD design models if applicable.
