编织绳的收缩率问题：请教高手！
type: polyester round braidedname:cord 0.65 mm without core
material: 100% polyester
construction: cover - 16 braid, core - polyester (1800 dtex), picks per 20mm - 28+/-1
diameter: 0.65 (+0/-0.1)mm
tensile strength: min. 30 lbs
elongation: max. 2%, load - 20n, duration - 12hrs, temperature - 23 c
wet shrinkage: max. 5%
这是编织拉绳的指标，但现在出现收缩问题，而且非常不稳定，造成因拉绳收缩而使产品长度收缩的问题。请哪位大侠能指点下迷津，怎么进行控制。谢谢！ 请试改tensile strength: min. 20 lbs
