瓜尔胶在经纱上浆中的应用研究

Study on the usage of guar gum on warp sizing

在浆料中减少PVA用量后,加入瓜尔胶对纱线进行上浆,测试上浆纱的各项性能。这种加入瓜尔胶的混合浆料的某些性能与现行混合浆料的浆纱性能相似,但瓜尔胶黏度较大,上浆纱耐磨性较差。

After reducing the dosage of PVA, the size mixtured with guar gum was used for sizing and the performances of the yam thus sized were tested. Some of sizing properties of this mixtured size with guar gum show similar to that of currently used mixtured size, but guar gum features a high viscosity which makes a poor wear-resistance of the sizing yam.
