1. VP (VAPOUR PHASE) finishing cotton non-iron treatment technology
It is a national high-tech technology in the United States. Its process is to sew fabrics that meet certain technical requirements into ready-made garments. It directly enters a special reactor for high-pressure spray fumigation treatment, and then uses steam cleaning. The American ATP Company (American Textile Processing Technology Co., Ltd.) currently owns this technology. The test results show that shirts treated with VP technology are not only anti-wrinkle and anti-shrinking, but also soft to the touch. Compared with untreated shirts, their breathability, moisture absorption, easy stain removal, and easy drying are all significantly improved. An environmentally friendly product that is harmless to the human body. The appraisal report of the National Garment Quality Supervision, Inspection and Testing Center believes that Youngor VP finished cotton no-iron shirt is a high-tech product, and its technical indicators all meet or exceed the national high-quality product standards. It complies with the relevant requirements of the State Planning Commission and the State Science and Technology Commission on the development of high-tech projects such as "natural fiber anti-wrinkle and iron-free products" in the field of light industry.
2. Five characteristics and related excellent properties of shirts treated with VP technology
Five characteristics: breathable, sweat-absorbent, easy to dry, no ironing, and environmentally friendly
Excellent performance: long-lasting styling, strong wrinkle resistance; soft hand feel, natural and comfortable; good breathability, moisture absorption and easy drying; strong color fastness; good shrinkage resistance.
3. Comparison with SSP and HP technologies
The world's chemical industry has developed three types of cotton-free ironing technologies. The first technology is called SSP, which involves ironing-free processing of fabrics during the production process, and then cutting, sewing, and "hot air setting" within a specified time and temperature. The second technology is called HP. After the untreated fabrics are sewn into garments, they are soaked in a resin-based iron-free solution, and then washed and set at high temperature. The first two technologies are Japanese patented technologies. The third technology is called VP. After the fabrics that meet certain technical requirements are sewn into garments, they are directly put into a special reactor for high-pressure spray fumigation, and then steam cleaned. This is an American patented technology.
From the analysis of processing theory and the comparison of the final processing results, the VP method can best maintain all the original advantages of cotton fabrics, and the ironing-free effect is the best. It can be said to be permanent iron-free and formaldehyde-free. has the lowest residual value. Judging from the technical appraisal results, all technical indicators of Youngor VP cotton iron-free shirts are in line with the national excellent standards; compared with products processed by HP and SSP methods, whether it is formaldehyde residual value, anti-wrinkle reduction, softness, In terms of breathability, hygroscopicity, easy decontamination, and easy drying, it is significantly better than products treated with HP method without ironing.
IV. VP equipment
As a new generation of shirt-free ironing equipment, VP equipment is generally composed of two parts: reactor (reactor) and exhaust gas processor (scrubber). The waste gas treated in the reactor is led to the sewage treatment processor through pipelines, and then hydrogen peroxide, sodium hypochlorite, and sodium hydroxide are injected into the processor through a water pump in corresponding proportions to neutralize and dilute the treated waste gas, and then render it harmless emission.
At present, the American ATP Company, which owns this technology, has only rented out more than fifty sets of VP processing equipment in the world. Youngor Group has exclusively leased two sets, making it the only domestic company that owns this set of equipment.
5. Practical operation
The most direct feeling it brings us is that the process has changed from complicated to simple. A process flow chart is used to represent it from washing → dehydration → drying → Resin processing → dehydration → drying → ironing → high temperature setting → packaging, but now you only need to put the shirts ironed in the workshop directly into the VP process operation box for processing, and then package them, and more than half of the intermediate process is cut off. , while the manpower was reduced by half. The second biggest benefit is that high-tech equipment allows consumers to "return to nature" and completely retains the natural characteristics of cotton fiber. It feels particularly soft and smooth, and is anti-wrinkle, anti-shrink, breathable, hygroscopic, and easy to remove dirt. , good color fastness, wear resistance and other advantages.
Youngor’s first domestic introduction and development of VP finishing cotton non-iron shirts is a high-tech that reflects the new trend of international clothing. The production line is complete and standardized, the technology level is advanced, and it meets the corporate standard Q/NYJ001- According to various indicators stipulated in 1999, the quality has reached the level of international and export-based similar products, and has good commercialization prospects. The flatness is higher than the 124 test standards of the United States (AATCC): small shrinkage, good hand feel, and strong breathability. . This product uses nail-free packaging and is the first green packaging for clothing in China. The process and technical equipment meet environmental protection requirements and are environmentally labeled products for the clothing industry. The expert group unanimously recognized Youngor VP cotton no-iron shirt as a high-tech clothing product in my country.
