Description

A kind of preparation method of aqueous wet process woven fabric bass
Technical field
The invention belongs to the production fields that water-base resin is used for synthetic leather, are specifically related to a kind of aqueous wet process woven fabric bass Preparation method.
Background technique
Island microfiber leather as forth generation synthetic leather leather on physicochemical property well beyond corium, at present in shoes The fields such as class, sofa furniture, automobile interior decoration, luggage gloves gradually replace corium, and dosage respectively accounts for half river with corium Mountain, it is believed that following as microfiber leather items environmental-protecting performance improves, microfiber leather dosage can be increasing.People's living standard It is continuously improved, causes the requirement to quality of life higher and higher, especially under national strength energy-saving and emission-reduction policy, for substitution The microfiber leather product feature of environmental protection of corium proposes requirements at the higher level, the especially feature of environmental protection, the feature of environmental protection of technique of the exploitation from material, Entire process of manufacture does not use organic solvent, this aqueous technology is the emphasis direction of the following leather products exploitation, and Major subjects are studied by each scientific research institutions.
Country's superfine fiber leather is produced at present, but is all non-environment-friendly products, due to common superfine islands-in-sea bicomponent The technology features of fiber leather not can solve the material of the product feature of environmental protection itself and environmental friendly property problem, especially skin The technical problems such as the nuisances such as DMF, toluene, smell, VOC in leather volatilization can not solve always, and described the said goods can not be real Existing environment protection requirement, is also just unable to reach the environmental protection index requirement of top-grade furniture, footwear and automobile leather.
Common people can be referred to as the synthetic leather other than corium rtificial leather or imitation leather, such as PVC, PU leather.And show Having in technology using Synthetic Leather is solvent based product, there is different degrees of solvent environment in process of production, It has greater environmental impacts.Determining island microfiber leather is used as synthetic leather of new generation on physicochemical property well beyond corium, at present Gradually replace corium in fields such as footwear, sofa furniture, automobile interior decorations, it is believed that future is with the microfiber leather items feature of environmental protection The raising of energy, microfiber leather dosage can be increasing.The microfiber leather product feature of environmental protection for substituting corium proposes higher want It asks.From the feature of environmental protection of material, the feature of environmental protection of technique, entire process of manufacture has not used the woven fabric bass that the present invention is developed Solvent, this aqueous technology are the major fields of the following leather products research and development.This product solves DMF in leather from source, The technical issues of toluene, the unwanted volatiles such as VOC.
Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of the present invention is to provide a kind of aqueous wet process woven fabric bass Preparation method, entire manufacturing process do not use organic solvent, and obtained water-based microfiber bass reaches absolutely environmentally protective and zero DMF replaces traditional PVA with water-soluble polyester, effectively reduces non-degradable problem caused by PVA, and water-soluble polyester Cost is relatively low, and the rate of sizing is high, has many advantages, such as to reduce production cost, protection animal and ecological environment.Using aqueous wet coagulation Technique, zero solvent in production process, zero DMF are generated, and are just really reaching the requirement of environmental protection.
In order to achieve the above objects and other related objects, the present invention provides a kind of preparation side of aqueous wet process woven fabric bass The preparation of method, the aqueous wet process woven fabric bass includes the following steps：
