Embodiment 1

[0060] In this embodiment, a new type of sea-island fiber synthetic leather base cloth is composed of water-soluble sea-island fiber through acupuncture to form a three-dimensional network structure, and the sea-island fiber needle-punched cloth layer is made of water-soluble PVA as the sea phase. Components, PA material is made of sea-island fibers composed of island phase components by laying nets and needle punching. The island phase components of the sea-island fibers account for 60% of the fiber cross-sectional area, and the sea-island components account for 40% of the fiber cross-sectional area. The fineness of the fiber is 1.6-14dtex, the breaking strength is 3-6cN / dtex, the elongation at break is 7-10%, the single fiber fineness of the island component is below 0.8dtex, and the PVA is water-soluble PVA masterbatch. The PVA masterbatch is formed by fusing raw materials in the following proportions by weight: 50 parts of polyvinyl alcohol; 15 parts of polyalcohol or salt ...

Abstract

The invention discloses novel sea-island fiber synthetic leather base cloth. The novel sea-island fiber synthetic leather base cloth is a net which is prepared from water-soluble sea-island fibers byneedle punching and is of a three-dimensional network structure; a sea-island fiber needle-punched fabric layer is prepared from the sea-island fibers with water-soluble PVA (polyvinyl acetate) as a marine component and a PA (polyamide) or PET (polyethylene terephthalate) material as an island phase component by lapping and needle punching, wherein the island phase component accounts for 60%-85% of a fiber section area, the marine component accounts for 40%-15% of the fiber section area, denier of the sea-island fibers is 1.6-14 dtex, breaking strength is 3-6 cN / dtex, elongation at break is 7%-10%, single fiber denier of the island phase component is 0.8 dtex or lower, PVA is water-soluble PVA mater batch, and the melting point is 180-190 DEG C; the melting range is 175-195 DEG C, and thethermal decomposition temperature is 210-220 DEG C. The invention further discloses a production technology of the base cloth. The problem of pollution caused by the fact that complex fibers are treated and prepared from traditional PVA chips by adopting an organic solvent is solved, and the purpose of composite melt spinning with island phase resin is achieved.

Description

technical field [0001] The invention relates to the technical field of superfine fibers, in particular to a novel sea-island fiber synthetic leather base cloth and a production process thereof. Background technique [0002] In the past, fiber synthetic leather used woven fabrics and knitted fabrics, and was gradually replaced by needle-punched nonwoven fabrics and spunlace nonwoven fabrics. Synthetic leather products using woven or knitted fabrics as base fabrics have poor elasticity and unsatisfactory surface style, and can only produce medium and low-grade synthetic leather products; synthetic leather products using ordinary needle-punched fabrics and spunlace fabrics It has a certain imitation leather effect, but the fiber is thicker and the density of the base fabric structure is low, which cannot meet the requirements of high-end products; after entering the 21st century, with the advancement of microfiber manufacturing technology, superfine fiber from indeterminate isl...
