• 浆纱主要应用于短纤单纱和无捻长丝纱。
This process is performed on single spun warp yarns and untwisted continuous filament warp yarns.
概述:
二、浆纱目的 —— 提高经纱在织机上的可织性
Objectives —— to adapt warp yarns to weaving on looms.
- 渗透性
Penetration
Penetration of the size into the yarn must be properly controlled.
- 吸湿性 - 均匀性
Hygroscopicity Uniformity
- 浆液粘性
Viscosity
The viscosity of the size mixture directly controls the amount of
penetration at a given temperature and roll pressure. Too little viscosity (too thin a mixture) will give excessive penetration
五、上浆后浆纱性能值得关注的几个指标 - 强力
Tensile strength
The greater the increase in tensile strength, the less
likelihood there will be of a break occurring,
particularly where weak places are excessive.
