Interpretive Summary: THIS STUDY EVALUATED FIBERS PRODUCED BY COTTON PARENTS AND THEIR PROGENY USING RESULTS GENERATED VIA THE STELOMETER, PEYER AL101, FIBROGRAPH, HVI, AFIS, FAVIMAT, AND MINIATURE SPINNING. WITH INCREASED PROCESSING SPEEDS, COTTON FIBER CLASSIFICATION AND COTTON BREEDING IMPROVEMENTS ARE REQUIRED. TRADITIONAL FIBER TESTING WAS COMPARED TO SINGLE FIBER TESTING AND MINIATURE SPINNING. A NEW SINGLE FIBER TESTING INSTRUMENT PROVIDED TRADITIONAL SINGLE FIBER DATA. THIS INSTRUMENT PROVIDED FIBER PARAMETERS SUCH AS FIBER CRIMP IMAGE ANALYSIS. RESULTS FROM THIS NEW INSTRUMENT MAY HELP EXPEDITE PROCESSING IN TEXTILE MILLS AND ENCOURAGE CERTAIN COTTON VARIETIES. A VARIETY WITH HIGHER STRENGTH AND CONTAINING MORE CRIMP MAY LEAD TO A FIBER WITH BETTER PROCESSING ABILITIES. IT MAY BE ADVANTAGEOUS FOR COTTON BREEDERS TO TRY AND DEVELOP NEW CONVOLUTED VARIETIES WITH INCREASED FIBER STRENGTH. THE PROGENY COTTON DISPLAYED BETTER-QUALITY FIBER AND YARN PROPERTIES TESTED UNDER A WIDE RANGE OF CONDITIONS.

Technical Abstract: THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE FIBERS PRODUCED BY COTTON PARENTS AND THEIR PROGENY USING RESULTS GENERATED VIA THE STELOMETER, PEYER AL101, FIBROGRAPH, HVI, AFIS, FAVIMAT, AND MINIATURE SPINNING. THE FAVIMAT, A SINGLE FIBER TESTING MACHINE, WAS USED TO MEASURE FIBERS FROM SAMPLES CONSISTING OF COTTONS CONTAINING TWO DIFFERENT PARENTS (FM832 AND MD51neOK) AND THEIR PROGENY. IN ORDER TO GET A REPRESENTATION OF CERTAIN FIBERS WITHIN THESE SAMPLES, THE COTTON WAS FURTHER DIVIDED INTO THE 17 AND 19 SUTER-WEBB ARRAY LENGTH GROUPS. THESE FIBERS RANGE IN LENGTH FROM 1.00 TO 1.125 IN (LENGTH GROUP 17) AND 1.125 TO 1.25 (LENGTH GROUP 19). TRADITIONAL FIBER TESTING WAS COMPARED TO SINGLE FIBER TESTING AND MINIATURE SPINNING. SINGLE FIBER TESTING WAS PERFORMED USING THE FAVIMAT WHICH MEASURES THE AMOUNT OF FORCE REQUIRED TO BREAK UP TO 210 cN WITH A RESOLUTION OF 1 X 10-4, WHILE THE FINENESS OF THESE SAME FIBERS CAN BE MEASURED FROM 0.5 TO 200 DTEX. FOLLOWING SINGLE COTTON FIBER IMAGE CAPTURING, FIBER FINENESS IS DETERMINED BY THE VIBROSCOPE METHOD. COTTONS IN THIS STUDY WERE BROKEN AT DIFFERENT LOADING RATES FROM 0.3 CM/MIN FOR THE STELOMETER, 2 CM/MIN FOR THE FAVIMAT, 13.6 CM/MIN FOR THE HVI, AND 25.4 CM/MIN FOR THE STATIMAT-M WITH RESPECTIVE FIBER OR YARN STRENGTHS OF 32, 32, 41, AND 27 G/TEX. CONCURRENTLY, CALCULATED CRIMP CHARACTERISTICS INDICATED THAT THE PROGENY FIBER CONTAINED MORE UNDULATIONS. THE PROGENY COTTON DISPLAYED BETTER-QUALITY FIBER AND YARN PROPERTIES TESTED UNDER A WIDE RANGE OF CONDITIONS.
