Printing and dyeing machinery technology: no continuous improvement will have no way to go

With computerized sewing machines increasingly becoming mainstream, electronic control after-sales service industry has become increasingly prominent. The electronic control system of the computer sewing machine is a relatively complex core component, and the country does not have a clear stipulation on the time and content of its warranty, and the industry standards have yet to be established. At present, the electronic control after-sales service is basically all corporate governance. The company's own warranty period is too short to protect the interests of consumers. Unregulated companies deliberately extend the warranty period but cannot cash it out. How does this chaotic situation affect the industry, companies, or consumers? How can consumers avoid risks?

Warranty Repair Kits Guard against Word Games It is not difficult to see from Prince Motors’s complaints about the merchant’s promised lifetime warranty but the consumer’s confusion over the two completely different concepts of warranty repair. Article 45 of the "Protection of Consumer Rights and Interests Protection Law" expressly states that business operators shall be responsible for the repair, replacement, or return of goods subject to state regulations or business operators and consumers agreeing to repair, replace, or retreat. If two repairs cannot be used normally during the warranty period, the operator shall be responsible for replacement or return. The repair package refers to repairs that do not require consumers to pay any fees during the warranty period. As for the warranty, there is no clear provision in the country. It can be understood that if there is a quality problem during the warranty period that needs repair, the merchant may charge the cost of the part, but no maintenance fee will be charged. In the interview, the reporter found that many consumers think that the warranty is repair, it is all free maintenance. Some bad distributors have also seized this point, playing word games and misleading consumers.

When the domestic computer-stitch sewing machine just emerged, the stability of the electronic control system was poor. In order to seize the market, manufacturers often took the form of repairs and repairs, that is, they provided sufficient electric control boxes at the dealers' offices, and they were replaced when they failed. Secured service in exchange for consumer trust. According to Qin Chaifa, president of Bowemas, this method is very effective when there is less sales of computerized sewing machines. However, as sales volume continues to increase, the burden on companies will become more and more serious. Therefore, at the beginning of its establishment, Bao Maikes established two principles. First, it is necessary to personally perform services instead of changing them. Second, there must be costs for services. Electronic components also have a certain service life and cannot be violated. Act regularly. Qin Cang law said.

In this remind consumers, when buying products, it is best to get the operator's written commitment, regardless of repair, warranty agreed in writing, to prevent bad businessmen from playing word games, stealing posts.

Violence promises to buy computer sewing machine, under the same conditions, the longer the warranty period, the better, but consumers also need to polish their eyes and carefully screen. At present, on the market, it is not ruled out that some non-standard enterprises use the after-sales service as a promotion method and have made a promise but cannot fulfill it. Therefore, after consumers hear the company's service commitments, they must carefully examine the company's overall strength and brand status. Consumers must first be responsible for their own, rational consumption.

According to industry insiders, the manufacturers promised a long repair period, which is equivalent to planting a time bomb for themselves. Once the promise is not honored, there will be a brand and trust crisis, and the credibility of the company will be greatly reduced. The creative clothing company had changed its equipment to Fushan this year because of the unfavorable quality of FDM and the fragile services. According to Zhou Haibo, a mechanic of Suzhou Qunhong Garment Co., Ltd., they are now saying that they support domestic products. However, blindly exaggerated advertising has caused people to really fail to love. If domestic companies put this part of human and material resources into product quality, improve after-sales service, and establish a system for tracking consumer visits, the results obtained will be better. Gold tablets and silver tablets are inferior to consumers' word-of-mouth.

The speed of replacement of electronic products is getting faster and faster. Many models of electronic products have already exited the market without exceeding the warranty period. In addition, how to ensure the supply of repair parts is also a big problem. Qin Cangfa believes that the limitations of the product itself are also difficult to achieve a lifetime warranty. Two years ago, Shanghai Wood House Garment Co., Ltd. encountered a similar situation, more than 10 years ago, the brother 737-313 computer sewing machine purchased due to aging components, the failure rate continues, but ultimately scrapped due to spare parts production. Therefore, in the final analysis, the so-called lifetime warranty is only a manufacturer's gimmick.

The quality improvement is a key service business. There are also problems in the FDM electronic control box mentioned in the Prince's Car Apparel and Creative Apparel. The most frequently reported problem is crash, burning of the motherboard, no response from the machine, and no power from the fuse. According to expert analysis, the above problems are related to factors such as defective software design, no overvoltage current protection device, and welding problems. According to the Qincang Law, in the first half of the year, the electronic control market was in short supply. Many manufacturers sold their goods indiscriminately, arbitrarily replaced the major component suppliers, passed product quality control, and experienced a sharp drop in aging test time, which would leave them with endless trouble. . Jiang Lei said: As a user, no matter how good the after-sales service, quality is still the first indicator of choice, and also hopes that manufacturers can perform necessary training for front-line maintenance personnel.

The "Consumer Protection Act" clearly stipulates that when a product has a quality problem, consumers should be responsible whether they find a dealer or any of the manufacturers. However, in the electronic control market, most dealers are not responsible for after-sales service, and they often have the ability to lay down all kinds of reasons to require consumers to find manufacturers, so as to shirk their own responsibilities, so that those manufacturers, Consumers push each other to push the consumer is a headache. Is the dealer really unable to undertake after-sales service because of the technology and spare parts? Actually not, because some dealers have begun to assume the responsibility of after-sales service of the electric control box, and the operation is very normal. Boomers has achieved remarkable results since the dealership training program started at the end of 2008. After one month or so of professional training, 30% of the more than 100 service technicians who have completed their jobs can repair 90% of defective products by themselves, about 50%. Can be handled on site and simple repairs. In order to encourage dealers to participate in the maintenance system, Baomaxi sells spare parts prices to the dealers at the purchase price, so that they can obtain certain benefits from them and make up for the service expenses. Qin Cangfa said: Even so, our maintenance costs are much lower than the cost of replacing the motherboard, ranging from a few yuan to a few tens of dollars, and the maximum is no more than two hundred yuan. Resolving problems in a timely manner and reducing the cost of subsequent use are also one of the main duties of after-sales service.

In the market, there are many brands of computerized sewing machines, and the quality of products varies greatly. How do consumers choose products with no worries? Industry insiders gave the following suggestions: First, select a product with a strong brand name; secondly, use a multi-directional operation to feel comfort in the product trial period, such as noise, vibration, and torque; and third, check the product's unpacking The rate and the production management are more confusing. Generally, the qualified rate for out-of-carriage manufacturers is low. Fourthly, the product's anti-jamming capability is checked. In addition, after-sales service can be guaranteed by pressing a part of the dealer's equipment.

This is an era of service victory. However, the present situation of domestic after-sales service is worrying. As the after-sales service is not in place, there will be more and more cases of product slow-moving and brand bankruptcy. After-sales is a double-edged sword, and the good word-of-mouth effect of after-sales will bring unlimited business opportunities and huge profits to the manufacturers. Otherwise, it will become a heavy burden. Bao Maike took the lead and picked up the banner of electronic control after-sales service standardization. He hoped that all manufacturers could act quickly and jointly regulate the market order.

The quality assurance standards vary from one manufacturer to another. In early June, two readers of our publication reported that the FDM electronic control system had a different warranty period in Jiangsu. According to Lu Wenjia, mechanic and repairman of Jiangsu Changshu Prince Garment Co., Ltd., the company purchased a total of nearly 300 FDM computer sewing machines. The model of the electric control box is type 02, which has been used for about 5 years. Previously, as long as the electronic control box had a problem, the local agent would immediately replace it, and did not need to pay any fees. However, starting this year, it would cost 200 yuan to replace an electric control box. The reason was that the warranty period had passed. At the time of sales, agents recently organized the “Experience Exchange on Energy Saving and Emission Reduction Experience” organized by the Ministry of Industry and Information Technology in Beijing and announced the first batch of 60 pilot demonstration enterprises for energy conservation and emissions reduction. Changzhou Hongda Electric Co., Ltd., Wuxi First Cotton Textile Factory, Hangzhou Open Source Computer Technology Co., Ltd., Tianjin Tianfang Investment Co., Ltd., Zhejiang Meixin Printing & Dyeing Co., Ltd., Zhejiang Huili Printing & Dyeing Finishing Co., Ltd., and China Textile Energy Saving Network Seven textile companies are among them.

Looking back at the list of companies that eliminated the outdated production capacity of printing and dyeing in 2010 announced by the Ministry of Industry and Information Technology, it clearly demonstrated the government’s firm determination in improving energy efficiency. According to the announcement of the Ministry of Industry and Information Technology, the backward production capacity for 201 companies in the printing and dyeing industry that need to be eliminated has reached 3.81 billion meters in printing and dyeing cloth. Relevant data show that in the first half of this year, the total output of printing and dyeing cloth in China was 20 to 30 billion meters, and the annual output of printing and dyeing cloth in China was 60 to 70 billion meters. Based on this calculation, the outdated printing and dyeing capacity will account for about 6% of the actual demand for printing and dyeing cloth in China. Judging from the previous rules, some market analysts believe that the adjustment is more detailed and the implementation of the phase-out policy directly to enterprises will be more conducive to policy implementation and supervision. On the other hand, it can also be considered in conjunction with the specific conditions of the enterprise. Avoid "across the board."

Under this process, for those printing and dyeing companies with advanced technologies and large scales, they may have a little easier life. For many small and medium-sized printing and dyeing companies, the competition they face will become even fiercer.

Timely adjustment is an inevitable choice for companies. It is known that airflow dyeing machines use air as the only medium to drive fabrics, and do not need other devices to assist. Water is used only for dyeing, so dyeing can be performed at a low bath ratio. For example, the ratio of cotton fiber bath to about 1:4, chemical fiber about 1:2 to 1:3 atomization dyeing liquor, so that the dye bath does not have to spray directly on the fabric, to avoid the strong water in the fabric while spraying accelerated dye penetration into the fabric fiber . Due to the low bath ratio, the consumption of additives, salts and alkalis is greatly reduced. The special washing system (VPR), which can wash the side row, provides 180 liters of clean water per minute for washing. The washing efficiency is high and the water consumption is reduced, which is 50% lower than that of the traditional dyeing machine. Due to the small amount of water, the time for water inlet, drainage, heating, cooling and other processes is reduced, and the time for the entire dyeing process is shortened accordingly. As the overall time is shortened, the power consumption is lower than that of the conventional flow dyeing machine.

Equipment update still needs new technology to follow up. Sanren Holding Group's subsidiaries, such as Hualun Printing and Dyeing, Jimei Printing and Dyeing, have all introduced automatic dispensing systems and digital printing machines, use humidity testing after baking, and appropriately shorten the pre-treatment process It saves energy and increases production efficiency. SAMURA rotary screen printing process can greatly save washing water. Paint printing and inkjet printing, reclaimed water recycling technology, printed nickel net recycling technology, etc., can greatly reduce energy waste and printing and dyeing wastewater discharge. They also invested 30 million yuan to install waste gas desulfurization and desulfurization equipment, cooling water recycling system, the existing 11 boiler flue gas waste heat and steam generated for recycling.

The introduction of Japan's stereotyped machine waste heat recovery devices like Jimei and Tiancheng can save about 15% to 25% of fuel and significantly reduce CO2 emissions. At the same time, the company's total thermal oil boilers installed a total of 9 sets of waste heat utilization devices, a total price of 3.5 million yuan, each set can save 6 tons of steam / hour, each ton of steam can save 140 yuan. Introduced advanced equipment such as Japan KYOTO liquid ammonia finishing and Airo air softener. Reduce the use of alkali, water, additives and softeners. The above-mentioned projects are all put into operation at present, and the effect of energy-saving and emission reduction is obvious.

The numbers can tell everything. The Sanyuan Holding Group Company only eliminated one old transformer and achieved an annual saving of electricity consumption of 20,000 kilowatts. Eliminating the use of heat-conducting oil furnaces, flue gas waste heat, and waste heat recovery and utilization can save 13,000 tons of standard coal annually. At the same time, Sanyuan Holdings actively develops and promotes new energy-saving and emission-reduction technologies, the “cold-pile” pre-treatment technology, cold-pile dyeing technology, and short-flow wet steam dyeing technology used in cotton and linen products, as well as automated dosing systems and digital The use of printing technology has significantly reduced product energy consumption and water consumption.

It is not difficult to see from the principle of automatic control of the fallback rate of Jimei printing and dyeing owned by Sanyuan Holding Group Company that the changes brought about by good equipment and technology are very great. The control of drying moisture regain in the dyeing and drying process can be achieved by controlling the drying temperature. For drying devices heated by steam, the drying temperature is controlled by controlling the steam supply. Therefore, controlling the steam supply of the drying cylinder is to control the moisture regain of the cloth.

The control of the moisture regain in the dyeing and drying process is related to three important indicators: product quality, production efficiency and energy cost. The reduction of energy costs is mainly aimed at avoiding over-bake. They have shown in practice that the control of falling moisture regain in the automatic drying process is more cost-effective than testing the moisture regain rate through hand testing. First, relying on equipment to digitize and automate production operations, workers' production quality indicators The control ability can then be programmed and standardized, otherwise it lacks an accurate evaluation criterion. Second, the result of proceduralization and standardization is to avoid waste, ensure quality, and increase production efficiency.

Therefore, it is very important to control the moisture regain. On the one hand, excessive drying will inevitably result in energy waste. On the other hand, from the pre-processing to the finishing process of this series of dyeing and finishing processes, the moisture regain of the fiber is one of the main physical characteristics that affect the success or failure of the process. Changing the moisture regain can greatly change the processing characteristics of the fiber, such as singeing, mercerizing, dyeing, fixing, pre-shrinking, calendering, nap, setting, etc., and the moisture regain data is reasonable and uniform to quality. Stability plays a decisive role.

Some small and medium-sized printing and dyeing enterprises have basically lost their production capacity after eliminating obsolete indicators and have stopped production. Some companies can rely on advanced equipment and relatively stable market efficiency to continue their production capacity and gain more room for development. In any case, the printing and dyeing enterprises that have survived and can develop healthily in this large phase-out will have to continuously adjust their thinking and continuously improve their production processes in order to meet the evolving market demands.

Said to be a lifetime warranty, our boss is to buy after the good after-sales service. According to Lu Wenjia statistics, nearly half of the FDM computer sewing machines of the Prince's car apparel have passed the warranty period. This situation was confirmed by Jiang Lei, a mechanic of Jiangsu Yixing Creative Garment Co., Ltd.. When the factory purchased the brand, the agent also called a lifetime warranty. After the problem electric control box was sent directly to the manufacturer, it would send a new one. Just pay the shipping fee.

The reporter visited a number of computer sewing machine manufacturers, the brand's commitment to the electronic control system warranty period from two years to five years, and even a lifetime warranty, warranty content is also different, the salesman on the warranty period and The explanation for the inconsistent content is even more pertinent. Professional electronic control system supplier Shanghai Bomax Electronic Technology Co., Ltd. has a warranty period of two years for the complete machine manufacturers, but the length of the commitment to the dealer or consumer after the delivery is long, and the whole machine company has the final say.

The reporter then contacted Ma Binwu, director of the office of Zhejiang Fangzheng Motor Co., Ltd. His answer is that this is a policy formulated by the sales department and further verification is required. The reporter sent several e-mails to verify the results and received the following e-mail response: Founder did not have any commitment on the company's computerized sewing machine for 6 years or lifetime warranty. The company adopted a sales agent-based sales model. You can directly consult the product seller. Lu Wenjia said that the response given by local agents is not clear.
