Abstract

The invention relates to a needle-punched non-woven base fabric, belonging to the technical field of a needle-punched non-woven base fabric production technology. The needle-punched non-woven base fabric takes sea-island fiber as a raw material and is made according to the steps of: (1) opening and pre-processing the raw material; (2) performing rough opening; (3) feeding into a primary cotton box; (4) performing fine opening; (5) feeding into a secondary cotton box; (6) feeding into an air pressure cotton box; (7) feeding into a carding machine; (8) feeding into a lapping machine; (9) feeding into a drafting machine; (10) feeding into a pre-needling machine; (11) feeding into an upper needling machine; (12) feeding into a lower needling machine; (13) feeding into a single-sided needling machine; (14) feeding into a double-sided needling machine; (15) feeding into a winding machine; (16) feeding into an ironing machine; and (17) feeding into the winding machine. The needle-punched non-woven base fabric has good air permeability and high wear resistance, and is soft and comfortable.

Description

technical field [0001] The invention relates to a needle-punched non-woven base cloth, belonging to the technical field of needle-punched non-woven base cloth production technology. Background technique [0002] It is a conventional manufacturing method to use needle-punched nonwovens as the base of artificial leather. Needle-punched non-woven base fabrics are generally made of polyester and nylon blends as raw materials, and are produced in conjunction with corresponding production processes. With the improvement of living standards, the current quality of needle-punched non-woven base fabrics can no longer meet the needs of consumers, such as air permeability, hand feeling, wear resistance and other properties. Contents of the invention [0003] The invention provides a needle-punched non-woven base cloth with good air permeability, soft and comfortable hand feeling and high abrasion resistance. [0004] To achieve the above object, the technical solution adopted in th...
