Problems solved by technology

Moreover, in the gluing process before flocking, in order to maintain a certain thickness of the rubber layer, degumming treatment is required. If degumming is not done properly, it will cause leakage or thick coating, which will seriously affect the quality of flocking. Use spraying technology instead of gluing technology can achieve the above

Embodiment

[0030] (1) Feeding and feeding: 60 groups of spindles are pre-loaded into the creel device, and each group of yarns passes through their corresponding multi-component yarn rings to ensure the running path of the yarns, so that the yarns will not be separated from each other. The entanglement will affect the production of yarn. After the yarn is divided, the yarn group is connected to the clamping device, and the yarn group is adjusted to clamp the yarn group at an appropriate position. The yarn group then passes through the yarn tension balancer to adjust the yarn tension to complete the feeding. Prepare;

[0031] (2) Pretreatment and decontamination: the yarn group is immersed in the pretreatment solution through the power roller, and the bubbles generated by the 2400W ultrasonic generator are used to assist the pretreatment solution to clean the dirt on the yarn and improve the cleaning efficiency. The cleaning temperature is 50~80℃ , and then the yarn group passes through t...

Abstract

The invention discloses a preparation method of thermal insulation flocked yarn. The preparation process includes the steps of yarn feeding, pretreatment, decontamination, drying, spraying, flocking,UV curing, brushing and winding. The production process of the flocked yarn can achieve continuous production, ensures the quality of the flocked yarn, a lot of time and cost are saved in the subsequent weaving process, and the production efficiency is improved. A heat-insulating UV-curable water-borne coating adopted in the yarn preparation process makes the flocked yarn endowed with excellent heat insulation performance, the flocked yarn has shorter coating curing time, and the performance requirements of a high-grade flocked fabric can be fully met.

Description

technical field [0001] The invention belongs to the field of textile engineering, and in particular relates to a preparation method of heat-insulating flocking yarn. Background technique [0002] Flocking is to use the principle of same-sex repulsion and opposite-sex attraction, so that the short fiber fluff is negatively charged, and the flocking material is placed under zero potential or grounding conditions, and the fluff is accelerated to fly vertically to the surface of the flocking material under the action of the electric field , because the flocking material is pre-coated with an adhesive, the fluff is vertically adhered to the material, and after the flocking is completed, it is dried or air-dried to obtain a finished product. In the field of flocking, fabrics are usually flocked. After pretreatment, gluing, flocking and brushing, a large amount of fluff, glue and pretreatment liquid are consumed, resulting in an increase in the cost of flocking fabrics. , in order...
