Background
Teslin is a special textile, mainly used for household articles such as dining mat, curtain and the like, and outdoor articles such as beach chair fabric, sunshade umbrella and the like.
The surface of the chemical fiber filament is coated with plastics and the like to prepare yarns with a sheath-core structure, and then the yarns are spun to obtain the textilene fabric, and various products are further prepared.
The yarns used by the traditional textilene products are all of PVC/PET skin-core structures, and the yarns are high-molecular composite yarns prepared by coating modified PVC plastics on the surfaces of PET filaments. However, PVC contains halogen, is not beneficial to environmental protection, and can cause certain harm to human bodies after long-term contact; the plasticizer and the like are added in the processing process of PVC, so that a large odor is generated, and small molecular auxiliaries in the PVC are migrated, so that a textilene product prepared from the PVC is sticky and crisp after long-term use. With the increasing requirement of environmental protection, PVC in a textilene product needs to be a more environment-friendly substitute, however, in the sheath-core structure of the yarn after the PVC is replaced by the polyolefin material, the adhesion force of the plastic layer to the fiber filament is obviously reduced, the separation of the sheath-core structure is easy to occur, the surface is not scratch-resistant, the hardness is higher, and the high-speed spinning can not be carried out. Therefore, the PVC substitute which is more environment-friendly is selected, and the problems of processing, adhesive force, surface hardness and other properties of the plastic layer, production efficiency and the like are also considered.
