About this file
This document is a Request for Information (RFI) for the procurement of polyester twill fabric with mechanical stretch properties for use in Navy physical training trunks. The Navy Clothing and Textile Research Facility (NCTRF) is seeking domestic manufacturers that can provide fabrics meeting the detailed material requirements outlined in Table I, including specifications for fiber content, weave, yarn, breaking strength, air permeability, colorfastness, and other characteristics. Interested parties are required to submit a cover sheet, 5-yard fabric samples, material details, technical data, production lead time, pricing, and country of origin information to NCTRF by June 28, 2024. Successful fabrics may be utilized in future Navy physical training uniform procurements. The agency involved is the Department of the Navy Naval Supply Systems Command.

1/ Drying Time Testing. The cloth shall be tested for drying time.
1a/ Apparatus and Materials
Wringer (motor driven) (see notes). Laboratory balance, accurate to 0.1g. White AATCC Textile Blotting Paper, 25 x 25 cm (see notes). Water, distilled. 250 ml glass beaker.
1b/ Test Specimens
The fabric samples and blotting paper should be conditioned at 65 +/- 2% RH and 70 +/- 2°F for a minimum of 4 hours.
3 test specimens per sample, 2 x 2 inches.
1c/ Procedure:
1. Test shall be run in standard conditions, 65 +/-2% RH and 70 +/- 2°F.
2. Weigh the conditioned specimen using a laboratory balance accurate to 0.lg.
3. Place I00 mL of distilled water into a 250 mL glass beaker.
4. Submerge the specimen in the beaker of water for 30 minutes. Make certain that the specimen is completely submerged to insure complete wetting.
5. Remove the specimen and sandwich it between two pieces of unused blotting paper. Pass the sandwich through the wringer with a dead weight load of 27.7 +/- 0.5 kg.
6. Immediately place specimen on the balance with top door of the balance open and record wet weight. Manually monitor weight at set intervals until dry or use an automated balance with capability to weigh specimen until dry (see notes). Record time to dry.
7. Repeat for remaining specimens. Average the 3 specimens.
2/ The test specimens shall be subjected to five washing and drying cycles before the shrinkage and/or elongation values are calculated.
3/ The specimen shall be laundered and dried three complete cycles. The specimen shall be dried after each of the three laundering cycles. Rated using the AATCC EP1, Gray Scale for Color Change and AATCC EP2, Gray Scale for Staining. Stain on all multifiber transfer swatches shall be evaluated.
4/ Rated using the AATCC EP 1, Gray Scale for Color Change and AATCC EP 2, Gray Scale for Staining. Stain on all multifiber transfer swatches shall be evaluated.
5/ Rated using the AATCC EP 1, Gray Scale for Color Change 6/ Rated using the AATCC EP 8, AATCC EP 9-Step Chromatic Transference Scale.
