The Wool Shrink-Proof Technology of Sericin Bonding Wool

For protecting the environment, reducing pollution and saving our precious natural resources, a new technology of wool shrinkproof was investigated in this paper. Wool/husks yarn was used as materials to knit fabrics.Through special steam treatment and sericin fixation finishing, the steaming conditions and the optimal technical parameters of sericin fixing were determined. The results showed that when steaming temperature was100 degrees Celsius and steaming time was 10min, the effect of steaming was good. The optimal technical parameters of sericin fixing were glutaraldehyde concentration 0.2%, treating time 60min and temperature 40 degrees Celsius. On this condition, the wool fabric shrinkage was 1.99%.

Study on the Effect of Slenderized Wool on Knitting Performance in Manufacturing Engineering

In this paper, wool yarns and the slenderized wool yarns were used as raw materials, and knitted under the same process parameter, many methods of testing were applied to analysis the wearing characteristics, An series of experiments show that there was a significantly improvement in the anti-pilling performance and air permeability, and the stiffness of the sample became smaller, increasing soft and comfort, but it had little effect on crease- resistance. The slenderizing not only improved the spinning count, but also enhanced the knitted properties by the structural transformation, was a good choice to develop the high-grade wool knitwear.

Promotional Effect of Ionic Liquid on the Enzymatic Shrink-Resistant Finishing of Wool Fabrics

In the paper, wool samples were pretreated by [BmiCl ionic liquid, followed by protease. The effect of ionic liquid pretreatment on the enzymatic shrink-resistant finishing of wool fabrics was studied. The results showed that the epicuticle was damaged by pretreatment, and the wettability of wool fabric was improved. These changes of wool surface made a promotional effect on proteolytic reactions. They could remarkably improve the accessibility of protease and thus increasing the efficiency of protease treatment. The weight loss of the sample pretreated with ionic liquid was dramatically increased, and the encouraging shrink-resistance was also achieved after the combination of ionic liquid and protease treatments.
