no. 1 approach

[0063] In a first embodiment of the present invention, the present invention provides a method for the preparation of polyester-based rayon (bend yarn), the resulting rayon and artificial turf or carpet based on the rayon. Its overall preparation process has, for example, image 3 The flowchart shown.

[0064] raw material

[0065] Suitable raw materials for use in the present invention are polyester based resin mixture raw materials. The mixture includes polyester and optional auxiliary agents (also called additives, auxiliary materials, etc.).

[0066] Polyester is generally a general term for polymers obtained by polycondensation of polyols and polyacids. As the polyester resin used in the polyester resin composition of the present invention, common thermoplastic polyester resins are used, and are not particularly limited. For example, polyalkylene terephthalates such as polyethylene terephthalate, polybutylene terephthalate, and polycyclohexanedimethylene terephthala...

no. 2 approach

[0102] In a second embodiment of the present invention, the present invention provides a method for the preparation of polyester-based rayon (straight yarn), the resulting rayon and artificial turf or carpet obtained based on the rayon. Its overall preparation process has, for example, Figure 4 The flowchart shown.

[0103] The process of pre-crystallization, weighing and batching, mixing and drying, feeding and melt extrusion, and cold water tank shaping of straight polyester artificial turf is basically the same as the process of bending (polyester) artificial turf in the above-mentioned first embodiment. Therefore, the selection of specific raw materials and the setting of equipment are performed with reference to the first embodiment.

[0104] When carrying out the straight yarn production of rayon, after carrying out cold setting (cold water tank setting), carry out the processing of following steps:

[0105] Preheating and dehumidification treatment

[0106] In som...

Abstract

The present invention relates to a preparation method and product of rayon based on polyester. The rayon is curved or straight. The present invention uses polyester as raw material to stably prepare artificial turf through melt extrusion. At the same time, the present invention further provides lawns or carpets based on the artificial turf.

Description

technical field [0001] The invention relates to a preparation method and a product of polyester-based rayon, belonging to the field of high-density filament production, and in particular to the field of artificial turf products for artificial lawns and carpets. Background technique [0002] The initial material used for artificial turf is nylon (PA). Nylon is the initial stage (starting stage) of the use of grass silk materials. In the early stage, the grass silk is made of nylon 6; the shape of the grass silk is similar to that of a carpet. At present, artificial turf has evolved from the first generation of artificial turf to the third generation of artificial turf. Artificial turf has developed from the original nylon material to the current polyethylene and polypropylene materials. [0003] There are currently three types of artificial turf products, which are divided into open mesh, straight and curved. The main materials are PE, PP and PA. Among them, the open mesh ...
