Preferably, after described guarantor's width of cloth drying and shaping step, surpass waterproof and protect width of cloth drying and shaping.
Another object of the present invention provides the gathered web that a kind of method produced according to the present invention makes, and said gathered web is a fish scale shape gathered web.
Adopt the inventive method to prepare gathered web, adopt hot and cold water alternately fabric to be carried out wrinkling processing, technology is simple; Easy to control; Adopt segmental dyeing, the phenomenon that dyeing quality is good, be not prone to dyeing flower adopts the inventive method to prepare gathered web; It is high to have improved finished product rate and production efficiency, constant product quality; Adopt the gathered web of the inventive method preparation, pattern presents the fish scale shape, and at the cloth cover distribution rule, cloth cover is active, has bionical effect, gives the pure and fresh aesthetic feeling of people, meets modern's aesthetic trend.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description:
Shown in Fig. 1-4, its gauffer of the fabric of present embodiment is to be the fish scale shape that rule distributes, and the style nature has modern aesthetic feeling; Meet the esthetic requirement of contemporary people to fashion, its preparation technology comprises the steps: mainly that destarch, hot water cold water alternate cycles cloth are wrinkling, dyeing and protect width of cloth drying and shaping, during preparation, adopts the HTHP overflow dyeing machine; When destarch, adopt conventional desizing, preferred destarch speed is 20m/min-40m/min, then adopting the method for hot water cold water alternate cycles cloth is that cloth is wrinkling; At first the water in the dye vat is warmed up to 60-95 ℃, preferred 80-90 ℃ will be distributed into more than the interior circulation 5min of dye vat, and preferred 5-10min carries out hot water circuit, and then the hot water in the emptying dye vat also injects cold water immediately in dye vat; Carry out the cold water circulation again, the time priority of cold water circulation is selected 5-10min for use, can fully reduce the temperature of recirculated water like this; Also can enhance productivity, and make corrugation effect better, the water of then having arranged in the dye vat carries out temperature-gradient method dyeing; Elder generation's hot water advances cloth and carries out hot water circuit, carries out the cold water circulation again, and cloth shrinks; Can make cloth cover fold more, corrugation effect is more obvious, dyes by dyeing curve as shown in Figure 4 during dyeing; Be 1 by bath raio (the heavy ratio with water of cloth) at first: 10-1: 15 inject cold water in the dye vat, and the water in the dye vat is warmed up to normal temperature, add levelling agent, acid successively, and have dissolved the ACID DYES that finishes; The pH value of adjustment dyestuff stirs to 4.5-5, then carries out temperature-gradient method dyeing; First section is adopted low speed to heat up, and is warming up to 60 ℃-70 ℃, and second section is warming up to 80 ℃-90 ℃ with middling speed; The 3rd section at a high speed to be warming up to 100 ℃-115 ℃, then between 100 ℃-115 ℃, is incubated 30-60min, and fast cooling to 80 is ℃-90 ℃ again; Preferred low speed programming rate is 0.4 ℃ of-0.6 ℃/min; Preferred middling speed programming rate is 0.6 ℃ of-0.9 ℃/min; Preferred high speed programming rate is 1.0 ℃ of-1.2 ℃/min; Preferred fast cooling is 100-115 ℃/min, in order further to increase the degree of folding of cloth cover, carries out the cold water washing after the fast cooling discharge opeing; After the cold water washing, cloth is protected width of cloth drying and shaping, the bake out temperature of preferentially selecting for use is 100-140 ℃, and drying rate is 30-60m/min, under above-mentioned technological parameter, protects the persistence that width of cloth drying and shaping can keep gauffer, reduces the modification of gauffer;
After described guarantor's width of cloth drying and shaping step, surpass waterproof and protect width of cloth drying and shaping; Preferred setting temperature is 160 ℃-180 ℃; Protecting width of cloth typing speed is 40-60m/min, and protecting width of cloth drying and shaping with this understanding can increase the typing effect, increases the fastness of typing.Surpass waterproof guarantor width of cloth drying and shaping after the width of cloth drying and shaping and can obtain to have the gathered web of waterproof effect.Ultra waterproof typing prescription can be: water-fast ultra waterproofing agent 40-100g/l, bridging agent 5-10g/l, bleeding agent 1-3g/l, the citric acid 1-3g/l (pH transfers to 4.5-5) of washing; Setting process: temperature 160-180 ℃, speed 40-60m/min* protects the width of cloth, surpasses the waterproof typing with this understanding, the cloth dimensionally stable of processing gained, and keep the original fold style of cloth cover.
In above-mentioned technology, destarch, guarantor's width of cloth drying and shaping and ultra waterproof are protected width of cloth drying and shaping and all can be adopted conventional production technology.
Above-mentioned process conditions are suitable for any fabric, are more suitable for the wrinkling processing in continuous synthetic fibre fabric, and corrugation effect is superior to other fabric.The dyeing heating curve all adapts to all ACID DYES combinations.
