Abstract
The invention discloses a production method for micro porous membrane fabric. The production method comprises the steps of uniformly coating a mixed resin at least containing water dispersive polyurethane and a water-soluble polymer on a surface of a base cloth in a coating manner; drying to form a membrane; then washing the fabric with the formed membrane to dissolve the water-soluble polymer out from the membrane; and finally drying and shaping to obtain the micro porous membrane fabric. The production method is environment-friendly and simple in process. The obtained fabric has relatively high air permeability and moisture penetrability and soft handfeel, and is suitable for use in various outdoor sports wear.
Description
Technical field
The present invention relates to a kind of production method of micro-porous film fabric.
Background technology
Along with the raising of people's living standard, consumer has higher requirement to the comfortableness of garment material, motion, Waterproof Breathable field especially out of doors, and supply falls short of demand especially for demand in recent years.At present, on market, main product comprises two large classes: a class is micro-porous type waterproof moisture permeating fabric, and a class is anapsid waterproof moisture permeating fabric.
The method of producing at present micro-porous type waterproof moisture permeating fabric mainly comprises two large classes: a class is wet-process coating, its main principle is by exchange occurs forming micropore being dispersed in solvent type resin system the water in DMF and tank, although this method is applied often at present, but there is serious environmental pollution, the shortcoming such as production efficiency is low.Another kind of is intumescent coating, its main principle is that the form by resin being carried out to mechanical foaming forms micropore, at present this technology further method be: in prescription, add a certain amount of pore-foaming agent as mentioned in Chinese patent CN 102425069A, the micropore that by the mode of rubbing in water, mechanical foaming is formed after drying and forming-film is connected, but general all very large of the micropore that mechanical foaming obtains, and also heterogeneity very of size, so it is many that it generally applies in the production of leather, and the application in Waterproof Breathable field is relatively less out of doors.
Summary of the invention
The object of the present invention is to provide that a kind of production method is simple, the production method of environmental protection and the good micro-porous film fabric of moisture permeability.
The production method of micro-porous film fabric of the present invention, it comprises the steps:
1. the hybrid resin that at least contains water dispersant type polyaminoester and high molecular weight water soluble polymer is evenly coated to the surface of base cloth by the mode of coating, then drying and forming-film;
2. by washing, the high molecular weight water soluble polymer stripping in film is formed to microporous barrier again;
3. final drying sizing, obtains product.
Above-mentioned hybrid resin, is generally first high molecular weight water soluble polymer to be fully dissolved in water, is then thoroughly mixed to form with water dispersant type polyaminoester, can add as required a certain amount of bridging agent and defoamer in the time mixing.
Above-mentioned high molecular weight water soluble polymer is: sodium carboxymethylcellulose, polyethylene glycol, polyvinylpyrrolidone, polyvinyl alcohol, hydroxyethylcellulose, modified starch or shitosan.The high molecular weight water soluble polymer aqueous solution in use will take into full account the compatibility with water dispersant type polyaminoester, and stripping property when drying and forming-film after washing.High molecular weight water soluble polymer is preferably sodium carboxymethylcellulose and hydroxyethylcellulose.
The content of above-mentioned high molecular weight water soluble polymer is 5%～30%, and the number of content directly has influence on the quantity of micro-porous of formation and the impact that breathable moisture permeability is brought, and preferred content is 10%～20%.
The mode of above-mentioned washing can be cylinder washing or liquid-flow dyeing machine circulating water wash.The condition of washing is 50～90 ℃ of temperature, 20～60 minutes time.The dissolution rate 80～99.9% of high molecular polymer.Water temperature is too low or washing time is too short all can not make the abundant stripping of high molecular weight water soluble polymer, and water temperature over-high or washing time are long, easily cause the problem such as hydrolysis and cost increase of polyurethane resin.Washing condition is preferably 60～80 ℃ of temperature, 30～40 minutes time.
The present invention has no particular limits for the requirement of base cloth, can be terylene, nylon, cotton or polyester-cotton blend etc.But because coating needs the technique through washing after dry, may bring impact to a certain degree to the color of base cloth, so the base cloth preferably using is nylon fabrics.
By the production method of micro-porous film fabric of the present invention, thoroughly solve the problem that environmental pollution and production efficiency are low, the careful homogeneous of its micropore, moisture permeability can reach 10000g/m
