摘要
应用Spinlab HVI900系统和X射线衍射强度-方位角扫描谱的多峰分离法测量了成熟棉纤维的初始模量M、3.2mm隔距比强度T、2.5%跨距长度L和微原纤螺旋角φ、微晶取向离散角α。并提出了成熟棉纤维种间、品种间品质性状与取向参数间的相关关系式为 M=3.73-0.04φ-0.06α(N/tex) 复相关关系r=0.762 T=58.08-0.30φ-1.33α(gf/tex) r=0.876 L=63.23+0.57φ-1.88α(mm) r=0.
The Spinlab HVI900 system and the computational multipeak resolution
method were used to determine qualitative characters and orientational parameters of cotton fiber
and developed the following relationships.
M = 3. 73- 0.04 (?)p-0.06 a (N/tex) r = 0. 762
T = 58. 08 - 0. 30 (?) - 1. 33 a (gf/tex) r = 0. 876
L = 63. 23 + 0. 57 (?)- 1. 88 a (mm) r = 0. 905
Where M is modelus of elasticity, T is 3. 2 mm gauge strength, L is 2. 5% span length (?) is mi-
crofibril spiral and a is the angle of crystallite orientational dispersion.
