this may result in yarns that are considerably weaker in some areas than in others, causing breakage to occur easily at the weak points.
从而引起应力的不均匀分配。纱线某段的强度比其它段要低,在纱线的弱段容易产生断头。
However, if the yarns are packed too tightly, the fabric will have reduced tearing strength, abrasion resistance and wrinkle recovery.
但是,如果纱线密度过大,织物的撕裂强度、耐磨强度及折皱恢复能力会降低。

The strength of yarns is due, in part, to the amount of twist that has been imparted. Strong yarns require considerable twist. However, beyond an optimum point additional twist will cause yarns to kink and finally to lose strength.
