Technical Field
The invention belongs to the field of fabric finishing and shaping, and particularly relates to an environment-friendly finishing and shaping process for Ding Yulian cloth.
Background
The shower curtain is a curtain-like article that hangs outside the tub with the shower head, or in the shower area. The bath curtain is mainly used for preventing water splash of a shower from splashing to a place outside the shower and has a shielding effect on a person taking the shower. As a bath curtain, the most important performance is to achieve the water resistance and the automatic dripping of water, and the bath curtain also has the enough mildew-proof function.
For a long time, the traditional satin curtain cloth achieves the effects of yarn fixing, water prevention and mildew prevention through the finishing of a coating adhesive coating, but the coating adhesive has certain influence on the health of a human body, and meanwhile, the coating can consume a large amount of water, steam, electricity, glue cost and the like, and a certain amount of cooling wastewater can also be generated.
With the increasingly strict monitoring of the environment-friendly production of the printing and dyeing industry in China, energy conservation and emission reduction become the key points of the long-term development of the printing and dyeing industry. There is therefore a need for improvements to conventional coating finishes.

The specific technical scheme of the invention is as follows: an environment-friendly finishing and sizing process for Ding Yulian cloth, which comprises the steps of spraying aqueous environment-friendly emulsion to a cloth cover before formal sizing, wherein the aqueous environment-friendly emulsion comprises 30-40% of aqueous polyurethane, 1-3% of stabilizing agent, 2-4% of emulsifying agent and water; during sizing, the baking temperature is controlled at 220 ℃, the vehicle speed is controlled at 80m/min, the padder pressure is controlled at 1.2kg/cm, and the liquid carrying rate is 70% and the overfeeding rate is-0.5%.
Coating with coating glue is not needed, before shaping, water-based environment-friendly emulsion is sprayed to a cloth cover in a spraying mode, baking and shaping are carried out after spraying, the water-based environment-friendly emulsion contains 30-40% of water-based polyurethane, meanwhile, a stabilizing agent and an emulsifying agent are added, drying is carried out, the water-based environment-friendly emulsion generates a firm polyurethane film on the surface of a fabric under the action of high temperature, yarns are wrapped by a self-crosslinking film forming effect, and the polyurethane film is also fixed between the yarns, so that a better yarn fixing effect is achieved, the phenomenon that the yarns fall off during cutting is avoided, after the water-based environment-friendly emulsion is sprayed, baking and shaping are carried out, the baking temperature, the rolling pressure and the vehicle speed of shaping are controlled, the yarn fixing effect can be improved by 40%, and consumption of various coating finishing processes is reduced.
Preferably, the aqueous environment-friendly emulsion is divided into two sprays, and the two sprays are sequentially formed into a first spray and a second spray respectively. The density of the satin cloth is larger, the water absorption is poorer, so that the aqueous environment-friendly emulsion is sprayed in two times, the time interval between the two spraying is controlled to be 20-30s, the aqueous environment-friendly emulsion sprayed for the first time has enough time to be combined with yarns of the fabric before the second spraying, and meanwhile, the aqueous environment-friendly emulsion sprayed for the second time can cover the surface defects sprayed for the first time.
Preferably, the two spraying directions are crossed, the included angle between the two spraying directions is 60 degrees, and the included angle between the spraying direction and the cloth cover is 60 degrees. The two spraying directions form an included angle with the cloth surface, so that the water-based environment-friendly emulsion is prevented from forming splash stripes on the cloth surface during spraying.
Preferably, the first spraying direction is directed toward the setting padder and the second spraying direction is directed away from the setting padder. The second spraying belongs to the final spraying before baking and shaping, and the spraying direction of the second spraying is the same as the relative moving direction of the shaping padder relative to the fabric, so that the flowing direction of the aqueous environment-friendly emulsion sprayed by the second spraying is consistent with the direction of the shaping padder, and the surface of the color Ding Yulian is smoother.
Preferably, the injection pressure of the first injection is higher than that of the second injection, the injection pressure of the second injection is 80% of that of the first injection, and the injection pressure of the first injection is controlled to be 0.2MPa. The spraying pressure of the first spraying is large, so that the water-based environment-friendly emulsion can intrude into gaps where yarns are interwoven, and the adhesive film fixing effect between the yarns is improved.
Preferably, the injection rate of the first injection is at least 20kg/min and the injection rate of the second injection is 80% of the injection rate of the first injection.
The beneficial effects of the invention are: coating with coating glue is not needed, before shaping, water-based environment-friendly emulsion is sprayed to a cloth cover in a spraying mode, baking and shaping are carried out after spraying, the water-based environment-friendly emulsion contains 30-40% of water-based polyurethane, meanwhile, a stabilizing agent and an emulsifying agent are added, drying is carried out, the water-based environment-friendly emulsion generates a firm polyurethane film on the surface of a fabric under the action of high temperature, yarns are wrapped by a self-crosslinking film forming effect, and the polyurethane film is also fixed between the yarns, so that a better yarn fixing effect is achieved, the phenomenon that the yarns fall off during cutting is avoided, after the water-based environment-friendly emulsion is sprayed, baking and shaping are carried out, the baking temperature, the rolling pressure and the vehicle speed of shaping are controlled, the yarn fixing effect can be improved by 40%, and consumption of various coating finishing processes is reduced.
