Abstract
The invention discloses a manufacturing technology for an environment-friendly comfortable sofa. The novel environment-friendly comfortable sofa is manufactured based on improvements on structures, filler, coated artificial leather and the like of sofas, thereby being durable, resistant to wear and quite comfortable to use; coated microfiber leather of the sofa, which is optimized particularly, is excellent in mechanical property, soft in hand feel as same as that of real leather, good in breathability and easy for dyeing, an excellent dyeing effect can be achieved at the temperature of 55 DEG C, formaldehyde content is reduced greatly, and accordingly more environment friendliness is achieved; since a complete biological method by enzymes and microorganisms substitutes for a chemical method for modification, naturalness and environment friendliness are achieved and residue is avoided.
Description
Technical field
The present invention relates to a kind of manufacturing process of sofa, particularly relate to a kind of manufacturing process of sofa of environmental-friendly and comfortable, belong to furniture manufacturing field.
Background technology
Sofa is the household goods popularized the most, and its seating is comfortable, various informative.But sofa is except wood sofa, in leather sofa, cloth sofa basic comprising, sponge is the material that must be equipped with.Sofa is the large consumer goods in furniture item, has a large capacity and a wide range.Along with the raising of living standards of the people, the development of science and technology, more and more higher to the requirement of sofa, the materials such as textile fabric, leather and artificial leather are added to the regulation of dry friction color fastness >=4 grade, be also provided with flame-retardancy requirements.In addition, also more and more comfort level and environmental-protecting performance is pursued.
As everyone knows, existing high-grade sofa mostly is natural leather sofa, and its comfort level is good, and durability is good, but environmental protection not.Natural leather is that animal hides makes a kind of polymer composite with higher-strength, favorable elasticity, higher hydrothermal stability and excellent sanitation performance through a series of physics and chemistry processing.Synthetic leather is for natural leather, the synthesis performance that it is emphasized " material ".It with the institutional framework of natural leather for target, the resilient macromolecular material of apparatus (as polyurethane) impregnated fiber layer (as Fypro, polyester fiber etc.), fibrage imitates the random 3-D solid structure of natural leather lamina reticularis, elastic polymer material forms the film with continuous microcellular structure, and obtained a kind of stuctures and properties all exactly likes the composite of natural leather.
Along with the development of superfine fiber chemical leather industry, its application also constantly expands, although its a lot of aspect is all than natural leather excellence (as mechanical performance), still there is larger gap in its sanitation performance, dyeability compared with natural leather.It is reported, the crust leather vapor pervious amount of natural leather is 800mg/ (10cm224h) left and right, and the vapor pervious amount of superfine fiber chemical leather is only 400mg/ (10cm224h) left and right.In fact, superfine fiber chemical leather has been water vapour permeability optimum in the middle of current all synthetic leather, and it and the main cause of natural leather sanitation performance difference are that the hydrophilic radical in natural leather on collagenous fibres is more than the hydrophilic radical in superfine fiber chemical leather.
The present inventor is in long-term production practices, and found a kind of manufacturing process of sofa of environmental-friendly and comfortable, it is from the structure of sofa, filler, and coated artificial leather many-side is improved, and obtains a kind of sofa of brand-new environmental-friendly and comfortable, it is durable, wear-resisting, uses as snug as a bug in a rug.
