Description

Making method for one-side coated fabric

Making louver is that professional general knowledge will be arranged, and needs quite to understand its composition and the purposes of yarn, the characteristic and the character of yarn class, can make best finished product; According to inventing into the result who is studied, for example: long fine Te Duolong 100% improves and is made into cloth through being processed into the softness product of weaving cotton cloth again, and through the typing of the temperature more than 200 ℃, its material is rigid to be best suited for being used for the shutter raw material.After the acrylic yarn is handled through distillation, become to be rich in fluffy soft character, do louver through after the special treatment again being made into cloth with two kinds of Te Duolong allotment specification, is rich in flexibility, full of elasticity, strong, can restore to the original state automatically through folding line, be best louver, under above all raw material allotments, use that effect is best.

Do a kind of tissue of different purposes, cooperate through multiple program and finish; The raw material mix of blade is formed in known road, to understand the stability requirement of blade then exactly, its must have a particular stiffness and elasticity and can keep strong vertically, not crooked and attractive in appearance, that will be controlled with a kind of resin, otherwise be subject to the influence of external environment, it includes weather, humidity, drying, temperature and crosses problems such as height.With inventor's practical study, as doing blade with artificial cotton, under 38 ℃ of irradiations of sunlight, blade can crooked, distortion, also can be crooked under humidity or become oval; As doing blade with nylon, when changing, temperature will change to some extent, for example can elongate at 40 ℃ of blades down of sunlight, temperature restores to the original state again if return to 28 ℃ of left and right sides blades, because they are influenced by environmental change all too easily, so the above neither suitable manufacturing louver of these raw materials, this phenomenon actual test of inventor are just learnt.

Resin composition and process that the present invention allocated are can not be misplaced order, otherwise will lose its effect according to following numeral order allotment:

One. the cotton hard resin (acrylic and water-based PU resin, ACRYLIC COPOLYMER) of acrylic, particle is thin, high temperature resistant, film is hard, toughness is strong, and usage ratio is 54%.

Two acrylic soft resins (acrylic resin, ACARYLIC POLYMER) are the acrylic latex of automatically cross-linked formula, film soft, and the fastness of friction is good, the transparency height, does not influence the coloured light of raw material.Because of the composition of use has difference, can be divided into DC-2440 and DC-2430 again and distinguish being easy to, usage ratio is 16%.

Three. ammonium water (the water-sprinkling agent has another name called waterproofing agent WATERREPELLENT AGENT) has waterproof action, and using composition is 2%.

Four. softener (SYNTHE TIC WAY EMULSION), have soft effect, increase feel elasticity, using composition is 7.5%.

Five. bridging agent (the U.S. fat of anti-ming tree the, MELAMI NE RESIN), when resisting the effect of chlorine damage wound and using chlorine bleach, make grey cloth minimizing flavescence itself, fiber increase hard effect, increase elastic handfeel, increase waterproof effect, mix use so this agent is good dose, it uses composition is 8%.

Six. promoter (having another name called catalyzer contact agent CATALYST), impel resin and fiber to form bridged bond and combine, do not become molten, insoluble polycondensation material, and hardened, its use composition is 0.5%.

Seven. tackifier (ACRYLIC ACID POLYMER), belong to high molecular polymer, do the time spent with other acrylic resin, can produce thickening power, when adjusting its pH value, can obtain required viscosity, its usage ratio is 12%.
