Description

Preparation process of anti-pilling worsted wool yarn
Technical Field
The invention relates to the technical field of wool yarn preparation, in particular to a preparation process of anti-pilling worsted wool yarn.
Background
The appearance of the textile is seriously affected by the pilling phenomenon of the textile. The premise of fiber pilling is that the fibers are fluffed, so short fiber textiles are more prone to pilling than long fibers. The factors influencing the pilling of the fibers are complex, but the essence of the method is that the surfaces of the fibers are not easy to break after fluffing and can be mutually entangled to form the balls. Therefore, wool fabrics, especially knitted or woven wool fabrics, have good elasticity and breaking strength, and can generate serious pilling phenomenon due to friction and the like when worn and used.
The anti-pilling finishing of the textile is mostly treated by adopting an anti-pilling finishing agent, and the processing principle is that the exposure of short hair fibers on the fiber surface during friction is reduced by covering high molecular substances or bonding among reinforcing fibers on the fiber surface, so that the anti-pilling effect is achieved by preventing the pilling on the fiber surface. The anti-pilling finishing agent for the textile mainly comprises the following components: organosilicon and its derivatives, polyurethane and its derivatives, mixture of organosilicon and polyurethane, and other high molecular substances.
Although the prior art can increase the pilling resistance of wool fabrics, the prior art has two defects: firstly, the finishing agent has poor fastness to washing, although polymers such as organic silicon or polyurethane cover the surface of the fiber, the fluffing phenomenon of the fiber can be reduced or prevented, but the bonding fastness of the polymers and the fiber is high, and the fluffing and pilling phenomena can be generated due to the falling off of the polymer covering along with the increase of the washing times; secondly, the soft hand feeling of the fabric is reduced, a cross-linking agent and the like are introduced in the finishing process, the fastness to washing of the combination of the finishing agent and the fiber can be improved, but the soft hand feeling of the fabric is obviously influenced, and the soft hand feeling of the fabric is sometimes more important than the special function of the fabric from the aspect of popular use requirements. In order to improve the pilling resistance of worsted wool products and maintain the soft hand feeling of worsted wool, it is necessary to research a preparation process of the pilling resistant worsted wool yarn.
