涤棉品种应用部分醇解PVA的浆纱实践

Sizing Practice of Using Partial Alcoholysis PVA in Polyester Cotton Variety

为了减少涤棉混纺产品浆料配方中PVA的用量,降低上浆成本,应用PVA-217SB低醇解度PVA、润力浆料进行了上浆实践。结果表明:应用PVA-217SB低醇解度PVA、润力浆料上浆后,减少了PVA用量,提高了浆纱质量,减少了经向断头,提高了织机效率,并且降低了用浆成本。

To reduce the use of PVA in size formula in polyester cotton blended product, and reduce sizing cost, sizing practice of using low alcoholization PVA-217SB and Runli size mixture were done. The result shows that using PVA-217SB and Runli size mixture can reduce PVA dosage, enhance sizing quality, reduce warp broken ends, enhance loom efficiency and reduce sizing cost.
