Double layer multi-strand wire prepared fiber rod and preparation method

Abstract

The invention discloses a double layer multi-strand wire prepared fiber rod and a preparation method thereof. The fiber rod is compositely prepared by heating multiple pieces of double layer multi-strand wires, each piece of double layer multi-strand wire comprises multiple strands of single-strand fiber wire, the single-strand fiber wire is singularly composed of inner core layers, the inner core layers are high melting point inner core layers prepared from the PP materials, multiple strands of single-strand fiber wire are bonded together with each other, through the heating method, the outer surface layer of low melting point is melted, while the inner core layers of high melting points do not dissolve, the remaining multiple pieces and multiple strands of the inner core layers of fiber wires can be bond together with each other by the physical effect produced by the dissolution of the outer surface layer, the preparation method completely puts an end to the use of glue and boiled oil water, redundant impurity substances are not generated, chemical substances are not generated in the fiber rod, and any kind of pollution cannot be generated when it is in the operating process or in the recycling process of a later period, so that the fiber rod becomes an environmentally friendly, green and pollution-free product, meanwhile, because there is no impurities to block the pores, the situation of the swelling and looseness of the fiber cannot occur, therefore, compared to the use of the traditional fiber rod of the glue, the present fiber rod has relatively strong capillary water absorption effect and long service life.

Description

technical field [0001] The invention relates to the technical field of fibers, in particular to a fiber rod. Background technique [0002] Existing water-absorbing fiber rods are made of pure PET (polyester) or PP (polypropylene) monofilaments. The fiber filaments are closely bonded to form a certain elastic rod-like structure, and the glue must be dissolved in oil and water, which has the following problems: 1. Due to the impurities inside the fiber filaments, the purity of the final formed fiber rods is not enough, causing the fiber rods to absorb water The amount is not high, and the residual glue impurities will block the capillary pores, affect the capillary water absorption effect, and the water absorption speed is slow, which affects the volatilization effect of the water agent. 2. Due to its chemical characteristics, the residual glue is not resistant to the corrosion of sesame oil or essence, which will cause the fiber filaments used as the water-absorbing core to ...

[0002] Existing water-absorbing fiber rods are made of pure PET (polyester) or PP (polypropylene) monofilaments. The fiber filaments are closely bonded to form a certain elastic rod-like structure, and the glue must be dissolved in oil and water, which has the following problems: 1. Due to the impurities inside the fiber filaments, the purity of the final formed fiber rods is not enough, causing the fiber rods to absorb water The amount is not high, and the residual glue impurities will block the capillary pores, affect the capillary water absorption effect, and the water absorption speed is slow, which affects the volatilization effect of the water agent. 2. Due to its chemical characteristics, the residual glue is not resistant to the corrosion of sesame oil or essence, which will cause the fiber filaments used as the water-absorbing core to expand, causing the fiber filaments to loosen, and the service life of the product will be affected. ; Moreover, after the fiber sticks containing impurities such as residual glue are discarded, it is not conducive to recycling and will have a negative impact on the surrounding environment
