I chose 10 different fiber types to use over the course of the experiment. 8 were selected initially, and 2 were added after pretesting revealed trends. Fibers were as follows: 98% Cotton 2% Elastic (Cascade "Fixation"); 70% Superwash Wool, 30% Nylon (Red Heart "Heart & Sole"); 100% Alpaca (Knitpicks "Alpaca Cloud"); 100% Tencel (Yarntopia Treastures "6/2 Egyptian Cotton Laceweight"); 100% Sugarcane (Arucania "Ruca Multy"); 55% Wool, 45% Silk (Fyberspates "Scrumptious Lace"); 100% Silicon (Rescue Tape); 100% PTFE (PTFE Thread Seal Tape Mil Spect-27730A), 25% Bufallo 75% Tencel (Buffalo Wool Company "Moon Lite"); 50% Soy Protein, 50% Milk Protein (Kollage "Milky Whey"). Ply number was recorded for each yarn.
Swatches knit on size 0 needles. The pattern used was as follows: long-tail CO 15 stitches, Stockinette stitch for 21 rows and traditional bind off. Natural fiber swatches were soaked briefly and blocked gently. Synthetic fibers were left unblocked. A 10 nm T-type thermocouple (Copper and Constantan, Omega) was arc welded under Argon atmosphere into row 21 of each swatch.
Swatches were secured with 2 hemostats and the CO edge was plunged roughly 1 centimeter into liquid nitrogen. Temperature was measured until the thermocouple reported -196 C. 5 measurements were taken per swatch. Mean rates of change were compared across groups. Observational data was recorded for absorbancy and flexibility.
New swatches were secured between 2 hemostats and plunged completely into liquid nitrogen. Flexibility was evaluated on the following criteria: Horizontal stretch, vertical stretch, scrolling, 180 degree twist, breaks, and glass like nature. Observational data was also recorded for each swatch.
Next up: Results (Data analysis takes time... ugh)
