Abstract
The utility model discloses an improved polyurethane basketball leather which comprises basic fabric and a polyurethane particle surface layer, wherein the basic fabric is formed by compounding a plurality of layers of non-woven fabric, the basic fabric is a reticular structure, the cross section of the basic fabric comprises lotus root-shaped through holes, and the microporous polyurethane particle surface layer is arranged on the upper surface of the basic fabric. As the non-woven fabric for constituting the basic fabric forms the reticular structure, the cross section has the lotus root-shaped through holes and the surface polyurethane layer is a microporous structure, the appearance and the internal structure of PU synthetic leather are progressively close to those of natural leather, the improved polyurethane basketball leather has good air permeability and moisture permeability, slippery and plump hand feel and excellent mechanical strength, and the physical properties are close to indices of the natural leather.
Description
Technical field
The utility model belongs to the tanning technology field, relates in particular to the PU leather that basketball is made in a kind of special use.
Background technology
The The Nomenclature Composition and Structure of Complexes of existing Synthetic Leather simulation natural leather is to be lamina reticularis with the nonwoven fabric through dipping, and micropore polyurethane layer makes as grain layer.Quite similar with leather, and have certain gas permeability, than ordinary people fabricate-leather more near natural leather.Be widely used in and make footwear, boots, case and bag and ball etc.But owing to as the structural reason of the multi-layer nonwoven fabrics of base cloth, exist poor flexibility, the problem that mechanical strength is low influences the quality of basketball.
Summary of the invention
The purpose of this utility model is the above problem that exists at existing Synthetic Leather, and a kind of improved polyurethane basketball leather is provided, and it has good springiness, smooth plentiful feel, good advantages such as mechanical performance.
The purpose of this utility model is achieved through the following technical solutions, this improved polyurethane basketball leather comprises base cloth, polyurethane grain layer, described base cloth is that multi-layer nonwoven fabrics is composited, described base cloth is a network structure, its section has lotus root shape through hole, is provided with one deck microvoid polyurethane grain layer above the described base cloth.
The network structure of described base cloth is that acupuncture becomes net or is bonded to net.
The production method of wet polyurethane synthetic leather is that adding DMF solvent and other filler, auxiliary agent in the polyurethane wet method resin are made mixed liquor, after the deaeration of vacuum machine, the dipping or be coated on the base cloth, put into then with solvent (DMF) and have compatibility, and with the incompatible water of polyurethane resin in, solvent (DMF) is replaced by water, polyurethane resin solidifies gradually, thereby form the porous epithelium, it is the microvoid polyurethane grain layer, pass through dry method veneer or surface again after ornamenting, after technologies such as surface printing, embossing, mill skin, form Synthetic Leather.
The beneficial effects of the utility model: reticulate structure owing to constitute the nonwoven fabric of base cloth, its section has lotus root shape through hole, the top layer layer of polyurethane also is a micro hole construction, thereby make the outward appearance of PU synthetic leather and immanent structure and natural leather progressively approaching, have high ventilation, poisture-penetrability, smooth plentiful feel, good mechanical strength, its physical characteristic all approaches the index of natural leather.
