Problems solved by technology

Since the jute fiber layer and the polyester fiber layer are stacked at intervals, and the jute fiber and the polyester fiber are not entangled with each other, the board prepared by this interval stacking has small and few pores on the board, and the board is relatively hard. , resulting in poor air permeability and poor sound absorption

Abstract

The invention relates to the technical field of sound absorption plates, in particular to a polyester fiber plate based on jute straw waste and a production process thereof. The jute straw waste is used as raw materials for preparing jute fiber; then low-melting-point fiber is prepared after melt-spinning; mixing, opening, carding, lapping, and needling reinforcing are conducted to obtain a fiberplate body; a fire retardant is sprayed to the fiber plate body and the fiber plate body is subjected to drying, press polishing and cooling; and the polyester fiber plate is obtained after cutting. The polyester fiber plate is prepared from the following components in parts by weight: 50-60 parts of the jute fiber and 40-50 parts of the low-melting-point fiber; and the NRC sound absorption coefficient of the polyester fiber plate is higher than or equal to 0.90. The production process of the polyester fiber plate comprises the following steps: (1) preparing the raw materials; (2) mixing and lapping; (3) reinforcing a fiber mesh; (4) spraying the fire retardant; (5) drying, press polishing and cooling; and (6) cutting and organizing. The polyester fiber plate based on the jute straw wasteis extremely high in hygroscopicity and air permeability and good in sound absorption effect, can realize effective anti-microbial, anti-mite, mould-proof and sound insulating effects, and is degradable.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing boards, in particular to a polyester fiber board based on jute straw waste and a production process thereof. Background technique [0002] The full name of polyester fiber sound-absorbing board is polyester fiber decorative sound-absorbing board, which is a decorative material with sound-absorbing function made of polyester fiber as raw material by hot pressing. Polyester fiber sound-absorbing board has the characteristics of sound-absorbing, heat-insulating and heat-insulating, and the material of the board is uniform and firm, full of elasticity, toughness, wear resistance, impact resistance, tear resistance, not easy to be scratched, and large board width. Because of its characteristics of decoration, heat preservation, flame retardancy, environmental protection, light weight, easy processing, stability, impact resistance, and easy maintenance, it has become the first choice of decorati...
