Maternity and Baby Products Require Improvement

It is known that several quality and security issues happened in recent years. These inevitably weigh on consumer sentiment. The whole market is in dire need of excellent maternity and baby products. Under this circumstance, the first Maternity and Baby Industry Quality Control Expo 2014 was successfully wrapped up on 22nd July, 2014.

This expo had participants came from related fields like food service industry, textile industry, clothing industry, cartoon culture industry, etc.. Lou Yingcai, the Assistant Dean of Zhejiang Textile Test Institute and General Secretary of Zhejiang Textile Standard Committee also took part in the expo. They gathered to discuss over the improvement and detection of maternity and baby products.

China has become the second largest consumer of maternity and baby products after America. Its market size is expected to reach 2 trillion RMB in 2015. Due to inadequate industry norms, quality and safety incidents of maternity and baby products occurs occasionally, which greatly dampen consumer moral.

With implement of Two Children Allowed Policy, maternity and baby products will be accelerated to integrate into each side of life and production. Thus the quality and security problems in this industry will also be paid with more attention in future.

Maternity and baby products is consistently associated with children’s health, thus the related products, brands and channels should be made to develope with deep cooperation. Enterprises in this field must provide qualified products with favorable price.

What’s more, quality control system in this line should maintain uniformity from raw materials to products, or even consumers. Last but not least, products with low quality must be forbidden to enter into circulation field.

Characteristics of Waste Streams Caused by Dyeing Knitted Fabrics

A large amount of waster streams or effluents is produced during dyeing knitted fabrics. Water streams produced in different sector of dyeing knitted fabrics pollute environment. Desizing, souring, bleaching, mercerizing, dyeing, printing, finishing, washing and other process can produce waste streams which contains harmful chemicals. For that, waste streams need to be purified before discharge to the environment.

Characteristics of waste streams: the followings are the characteristics of waste streams.

Desizing: Size materials are used on the surface of yarn during weaving. The process removing size materials form the fabric is called as desizing. Possible pollutant in water is Starch, Glucose, CMC, PVC, Resins, Fats, and Oils etc. Waste streams have high BOD (35-50%).

Scouring: Scouring can remove impurities of textile materials. Waste water contains NaOH, Na2CO3, Waxes, Grease, Fragments of cotton etc. Nature of waste water is strongly alkaline, dark color, high BOD (30%) of total.

Bleaching: Bleaching can remove natural color of the textile materials which also causes waste streams containing Na(0Ocl)Cl, NaOH, Cl2, H2O2, Na2O2, acids etc. Nature of waste stream is alkaline, BOD (5%) of the total.

Mercerizing: The process can improve the physical properties of the fiber, producing waste streams. Pollutant in water is NaOH, H2SO4, Na2CO3 etc. Nature of waste water is strongly alkaline, BOD (less than 1%).

Dyeing: The process can produce a large number of waste water. Possible pollutant is various types of dyes, salts, acids, alkalis, soap and detergent etc. Nature of waste streams is strongly colored, fair BOS (6%) of the total.

Printing: Printing forms carious types of decorous design. Possible pollutant is colors, pigments, gums, oils, acids, different salts and other auxiliaries. Waste water is highly colored, oily appearance, BOD (6 to 10%) of the total.

Finishing: Possible pollutant in water is Traces of Starch, Resins, Softeners, and Stiffeners etc. Nature of waste water is low BOD (2 to 4%) of the total.

Effluent treatment plant (ETP) should be set up for protecting the environment from the influence of the waster streams.

Objectives and Requirements of Soft Winding for Dyeing Knitted Fabrics

Dyeing knitted fabrics is quite special. Knitted fabrics must be packaged after having been packaged. Soft winding transfer knitted fabrics from paper cone to spring tube or plastic tube. Various winding machines are used for soft winding section. Different parameters having influence on dyeing process directly should be maintained.

Soft winding which is the first step for preparing yarn for dyeing plays a key role in yarn dyeing industry.

The following objectives should be gained during soft winding section

Making soft package (Density should lie between 0.300 and 0.350 gm/cc
Transferring yarn from cone to spring tube or plastic tube
Making free cone from yarn to facilities next process
Decreasing the density of package
Removing unwanted materials from the package
Facilities batching operation

Requirements of soft winding: Various parameters should be set based on requirements of package which is best for yarn dyeing. The followings are the requirements of soft winding.

Density lies between 0.30 and 0.35 gm/cc
Winding is on the basis of yarn count.
Tension of yarn must be kept strictly. More tension makes the package hard and less tension makes the package soft. Softness of package should be acceptable for better dyeing.
Winding floor must be kept neat and clean.
Winding parameter should be set wisely for different yarn count.
More tension can make hard yarn and low tension make soft package. For that tension must be accurate.

Get rid of pollution ‘short legs’ keqiao area businesses have turned to digital printing

The face of increasingly severe environmental pressures, many printing companies keqiao zone set their sights on less polluting digital printing, and some companies even at the cost of introducing new technology digital printing equipment abroad.

Vigorous investment in digital printing
Keqiao Development Zone is located in a small and medium enterprise printing, has decided to invest $ 3 million from abroad a digital printing machine. “Purchasing a first try, if good, will present three flat screen digital printing equipment, all changed.” Ms Chan said the person in charge of the enterprise, and now increasingly demanding environment, we do not want to sewage problems suspense.

Recently keqiao area printing digital printing business operators to increasingly high degree of concern, enthusiasm for investment in digital printing high. Over a large-scale printing and dyeing business owners these days, Mr. Zhang has been shuttling between Shanghai and Hangzhou, study current digital printing production and market conditions. Zhang said, turning from digital printing dyeing, re-learn everything, there is an old saying called “the observatory.” So, why such a large campaign Zhang? “Digital printing is only in the last part – when washing produce very little waste compared to traditional printing can certainly solve the sewage problem.” Zhang said, the investment of digital printing, traditional printing can get rid of the pollution of the “short leg.”
Digital printing due to ink-jet printing, dyeing process which dyes remaining only 5%, while the most advanced of its traditional printing equipment also dye the remaining 30%. Dye surplus, the more and more water, the higher the concentration of wastewater, sewage treatment more difficult it his.

Digital printing technology matures

Digital printing, dyeing and printing industry in keqiao area is no stranger, but a few years ago due to the speed restriction has been used only for proofing production lines become climate. Located in Binhai Industrial Zone RGB Dyeing Co., Ltd. is an earlier attempt to digital printing business, its products in the domestic market will soon hit a new world.

In recent years, digital printing technology matures, digital printing production is also a substantial increase in the use of digital printing technology is rapid, speed is no longer the bottleneck of digital printing. “Three or four years ago, 1 hour print speed of 5-10 m have been considered high-speed, and now has achieved 100 meters above the hourly rate.” “RGB” general manager Chen Yuming said that with the increase in production, these in digital printing costs has also been reduced from the original ink costs only 100 yuan per meter, down 10 yuan now.
Chen Yuming been concerned keqiao digital printing industry, he told the author, along with cost reduction and product individual needs, the last three years, investment in digital printing business keqiao increasing, especially last year, the number of digital printing machines increases the hundreds. Digital printing is becoming a hot spot for investment keqiao dyeing enterprises, a number of well-known digital printing equipment manufacturers have come to Shaoxing sell equipment, such as Hangzhou Honghua Digital Technology, Hangzhou, computer technology and other open-source companies are still in Shaoxing has a distribution network.

Investment in digital printing to pay attention to what
Traditional textile printing business is not very different, easy to form a vicious price competition. So, digital printing can replace traditional printing it? “Difficult!” One in 10 years of study of the digital printing industry, told the author, only the cost of printing, traditional printing is about 2 yuan per meter, and digital printing at more than $ 10, this cost gap on the leading digital printing in Price competition tends to be a disadvantage. Chen Yuming also admitted that because of the price, he often suffered its customers “abandoned.”
. “Currently digital printing biggest competitor is the cost,” Chen Yuming believes that today’s textile printing, pop elements change quickly, the need for more design; orders yardage getting shorter, but more complex designs, fastness also higher; and as people’s environmental awareness, tolerance and fabric color variation tighter specifications, digital printing and dyeing industry must be the direction for future development.

So, the current investment in digital printing and dyeing enterprise transformation should pay attention to what? Chen Yuming has proposed to locate a clear second to consider the return on investment, then there need to continue training, efforts to increase staff to operate digital printing expertise, ability to learn self-control digital printing equipment and ink control. The only way to make the digital printing technology to get faster and better development.
