What is the the principle of shifting rib circle knitting machine and point of its commissioning?

Posted on

First, the principle of shifting rib circle knitting machine
On the shifting rib circle machine knitting circle shift organization, the first coil should move the needle on the dial. Needle grooves in the cylinder, the expansion ring is inserted with the latch needle plate, expanding ring of spring steel sheet is bent, one end of which is secured to the needle bar, and the other end close to the knitting needle bar groove, and the other there incision (also known piece shoulder) on expanding circle piece.

Move ring installed on the machine has a triangular base and rib needle selection mechanism used exclusively for moving coil (flower disc, put chip, inserts, roller, etc.), the need to move the needle circle rises above the ring back location. At this point, expanding circle piece penetrates the coil, the coil expansion, and resting on the incision, followed by the needles on the disc outwardly (dial needles can rise to the position of the needle is not unseating ), through the needle bar and the diffuser ring is composed of sheet voids and move the dial needles, the cylinder coil is hooked on the knitting needles. With the decline of syringe needles, between the coil from the syringe needle knitting circle piece rod and extend the gap at the slide. When the syringe needle continues to drop, the stitches from the needles of the cylinder needles and take off, and transferred to the needles on the needle plate at this time, the needle of the needle is no coil. When the needle reaches the next before a loop system (ones), when the syringe needles rise, by means of the tongue opener (also known as the open needle), the needle off the tongue (that is, the coil is removed syringes the needles of the tongue) is open, ready to weave.

Using shifting circle weave rib-knit organization called the shifting circle, also known as leno. It is based on the basic organization of the weft, according to the pattern required to shift some of the ring coil, the coil that is transferred from one to another wale wale formed. Because of the way the law shifting circle varies, the use of different types of organization (flat needles, interlock, rib tissue) and shifting circle way, you can form a variety of patterns effects (patterns) in the knitted fabric surface.

Second, the shift points rib machine debugging circle
1 shift in the security circle rib machine maintenance, hedge cloth (also known as the hanging fabric, buckle cloth), you need to dial cloth cover on the needle, which is different from other knitting machine. The reason is that the syringe with the needle incision easily hooked cited cloth, not easy unseating.
2 Oil is not too tight, put the appropriate length of the coil length. The main reason is to be transferred into the coil elastic expansion ring films, needle loop is rapidly expanding, causing tension mutations.
3 coiling tension can not be too large, otherwise prone to holes. In order to ensure the smooth progress of weaving, coiling tension adjustment should be slightly smaller than the other product specifications.
4 take lag (after eating, asynchronous) into a circle, and note the dial needles pressure needle not too deep, or prone to holes.
5 weaving a yarn tension control in general 4.9 ~ 7.84 cN (5 ~ 8 g) is appropriate. Too prone to holes, too small needle prone to leakage.

Traditional Printing Another Way – Imitation Digital Printing

Posted on

20140726231658
Printing is the essence of flowers, flower attributed to fashion, digital technology has created a digital fashion development, and people turn to the pursuit of fashion Forced advances in technology. With the continuous development of digital printing technology, the traditional printing industry to further shocks. But it can not completely replace the traditional digital printing, then how reasonable arrangements between digital printing and traditional printing complementary, into new technology to enhance the point? Generally have the following observations and recommendations:

1, color digital printing on relatively poor. A large number of digital printing products are similar to the original work or imitation color. Can not be compared with the traditional color printing; does not specify a color for their customers, especially spot demanding customers.

2, high cost of digital printing, the loss is high. When digital printing process due to nozzle clogging, uneven friction fabric, wrinkles and the adverse higher, not completely mass production.

Given the status of traditional printing and digital printing, as well as the advantages and disadvantages of digital people for the pursuit of fashion, combined with digital printing and traditional printing, digital printing technology came into being fake!

Digital printing is an imitation of the digital inkjet printing technology with the perfect combination of traditional network-based application of new technology, which is different from traditional innovative use of spot color separations private network technology in the existing network platform printing technology, breaking the cycle of songs and limiting devices to be close to the cost and efficiency of the traditional printing digital printing printing comparable to the effect of, great to meet the consumer demand for digital fashion pursuit.
Imitation digital printing technology with printed fabrics, not only has the characteristics of low-carbon environment, the more important is the color change fabric richer, lifelike and vivid flowers. A three-dimensional fabric, especially for young people’s tastes. On the other hand, imitation digital printing in energy efficiency compared to ordinary printing to save a lot of value-added products is 3 to 5 times digital printing.

Imitation digital technology to meet today’s dominant individual consumption. Now clothing fashion cycles are getting shorter, pattern changes more quickly, producing increasingly high demand, order smaller quantities. Cost and time consumed by conventional printing plate, no matter how it is difficult to meet the requirements of the modern trends in printing, digital printing and imitation has unique advantages in this regard.

Meanwhile, digital printing has great potential in foreign markets. Europe is the biggest digital printing products, demand and production, digital printing has penetrated into apparel, home textiles, customization, and other fields. Small volume, variety, and rapid response mode greatly enhance the value chain clothing brand.

In short, digital printing as a revolutionary technological advancement for textile printing industry to bring endless vigor and vitality, but its price is expensive, especially nozzles, ink and other supplies not yet fully mature, operating costs are extremely expensive, and there is limited proofing small batch production, the real mass production also needs a little time to verify. The imitation of digital printing as a new means of digital printing technology, perfect make up the traditional printing and digital printing imperfections, suitable for mass production of digital flowers, flower power is not inferior to the performance of a digital direct injection and transfer printing, and bright colors degree, feel, color fastness, penetration is much better than the digital direct-injection and transfer printing, after all, a high-volume digital production orders.

When taking about the development of textile industry, Christine Schindler illustrates cross-border cooperation, “many Chinese companies purchase European textile machine manufacturers. Some Indian companies choose to found plants in American. Africa is also regarded as a feasible investment districts for some European and Chinese companies.

In his view, global textile industry chain is undergoing shuffling integration from fiber production to sales. This means textile enterprises must make constantly change to follow changes of market and seek for innovation and cooperation. In the zones that are out of local technic capacity, companies should join hands with others and build up business relationship throughout the world.

Christine Schindler regarded that the future development of global textile industry can be analyzed from long-term side and short-term side.

“For short-term prospect, international economy still stays in recovery phase and people know nothing about future growth. However, the investment on textile machines was not influenced at all. In this period, prices of cotton are comparatively high. China yarning enterprises improve their competitiveness through investment on machines.” He said, “For long-term prospect, more and more people enter into consumer market. With growth of global GDP, especially that of India, China and other Asian countries, consumption in textile industry is increasing. We can confirm that textile industry, particularly textile machine field, has a promising prospect. ”

In the end, Christine Schindler added, “ China textile industry has presented constant high-technology application and high ratio of investment. Apart from that, China also has obvious advantages over raw material cost, energy cost, mechanical equipment cost and so on. At the same time, other Asian countries do not have as big market as China. Therefore, cooperation is needed to promote development of global textile industry.

Textile Enterprises Turn Waste Clothing into Wealth

Posted on

With improvement of people’s life, the refresh rate of clothing is accelerating constantly. Piles of old clothing have become some kind of burden for many families. In July 2014, Environmental and Resources Committee of China Textile Industry Association organize No Old Clothing Discarded – China Brand Clothing Recycling Programme. From this activity, some enterprises from Keqiao detect business chances and work on the old clothing

1. Donating old clothing in the past was usually refused by grantees.
Several years ago, people used to donate those second-hand clothing. This can help others on one hand and solve the accumulated old clothing problems on the other hand. However, according to survey, we found that donation of old clothing are often refused in Shaoxing.

2. Value of discarded old clothing each year equals to half of Daqing Oilfield.
The production of clothing, from silk to cloth and then garment, cost numerous energy and time of works, as well as countless power. However, they are discarded in the end. Shortly before, China Textile Industry Association indicated that: China generates about 20 million tons of old textile products. Completely recycling those products can provide chemical fiber and natural fiber which can produce up to 24 million tons of crude oil. This amounts to oil production of nearly half of Daqing Oilfield. At the same time, they can reduce 80 million tons of carbon dioxide emissions and save almost one third of cotton area.

3. Many enterprises of Keqiao get involved in this activity to turn waste into wealth.
Facing piles of old clothing, many textile enterprises in Keqiao have discovered business chances. They work positively on exploring recycling and generative technology of fiber.

Guqiandao Green Fiber Co., Ltd. strives to develop intensive production and green circulatory economic industry. In 2012, they founded Zhejiang Lvyu Generative Macromolecule Material Company. This company mainly engaged in recycling waste textile products to produce recycled polyester chip and melt of high viscosity.

Selection of knitted fabric dyeing auxiliaries common quality problems

Posted on

1. color fastness unqualified
Color fastness to light fastness, washing fastness, perspiration fastness, rubbing fastness, fastness to open China, ironing fastness, these fastness lies dye structural performance, but also with the fibers, dyes closely related to the concentration, dyeing and finishing processes, external conditions, so whether the target color fastness, the key is to choose the dye, followed by dyeing and auxiliaries applications.

When dyeing system permits must be based dyes, fibers and customer indicators reasonable assurance that the dye additives help, under certain conditions, as far as possible on the ground dye fastness fiber to make it fully fixed. For the additives, the first, a good choice and pro-dye leveling agent, the dye slowly and evenly, fully dyeing fibers; Second, plus a chelating agent to overcome the dye and metal ions from the water floating color, and reduce hydrolytic activity of the dye in the water; Third, choose good soaping, go to the net floating color, and anti-floating re-stain fabric;; fourth is to select the appropriate fixative, the current sublimation fastness, sun outside fastness is no ideal fixative for soaping fastness, perspiration fastness collapse, the indicators rubbing fastness, etc. are excellent fixative to choose from.

2. brittle damage
Brittle damage showed a strong decline in profit before oxygen bleaching due to improper handling and other processes cause damage or even brittle outer holes and other reasons, there are generally two types of brittle damage caused by dyeing reasons, one is brittle damage such as sulfur black dye caused required to improve the anti-brittle agent, as well as dyeing vat dyes and strong oxidizing agents strong reducing agents, such as damage to the fibers brittle; Second stage or the improper dyeing and stages with acid, and acetic acid is generally used, and currently on the market supply of some alternative acids, some of these alternative acids like BASF’s strong organic acid buffer, excluding sulfuric acid, hydrochloric acid, phosphoric acid, and even superior performance than acetic acid, the chemical company Ningbo Runhe buffer acid is also true these buffer acetic acid but also to improve some of the shortcomings (such as glacial acetic acid winter inconvenient to use, stimulating taste great, residual acidity, and metal ions in water such as Ca +2 Mg +2) remain in the fabric caused by the combination of dark shade wilt etc. etc.). Some with H2SO4, HCl, H3PO4 and other alternative acid, not only cause changes in dyeing shade, dyeing and finishing equipment and pumps for corrosive effect, but during and after the acid residues can also cause fabric damage brittle under acidic conditions.

3. Wrinkle Article
Wrinkles are generated mainly of equipment reasons, the amount of cloths has installed causes the bath ratio and the processing operation of the reasons and other reasons, the amount of fabric mounted equipment, the pressure and friction between the pump power and the tension of the fabric and the fabric are affected fabric cloth flatness; bath ratio will affect the size of the flatness of canvas; process operations caused by too much fabric floating foam additives and process skid heating and cooling operation appears cold and hot phenomenon will cause fine wrinkles of the phenomenon . The current bath lubrication wrinkle agent, bath treasure, bath softener can improve fine wrinkles of the phenomenon, but if the device does not improve, poor process control, plus bath lubricant alone can not completely avoid the fine wrinkles of produced.

4. Wind India
Air India has little to do with the additives, the key is to dye their own performance (acid resistance) and fabric with pH, acid gas air humidity and so on, such as direct dyes Fast Turquoise Blue GC, chrysophenine G, etc. in case of sour gas prone to wind and India; activity in Turquoise Blue KN-G, brilliant orange X-GN and other pH sensitive and easy to produce on wind India; dyes such as yellow RGFL in base-sensitive, but also easy to produce wind India . For aid, the middle and must do to make cloth as pH = 7. Therefore, attention must also breed and when acids and bases, as far as possible with glacial acetic acid or organic acid substitution, can never substitute acid containing H2SO4, HCl and other strong inorganic acids, bases with Cheung also choose to ease as much as possible Some.

5. color flowers (including color, color does not match the sample, etc.)
Flower color dyeing process is the most common, the most common quality problems, the causes are:
(1) the development and operation of process issues: developing technology to produce an unreasonable or improper operation flower color.
(2) equipment problems: If the disperse dye polyester heat-setting machine inside the oven temperature varies also easy to produce color-color flowers, dyed rope pump power shortage also cause colored flowers.
(3) Dye problem: dye aggregation prone, poor solubility, poor compatibility, temperature, pH is too sensitive and are easy to produce color flower color. Reactive Turquoise Blue KN-R as easy to produce colored flowers.
(4) water quality problems: poor water quality, causing the dye and metal ions or dyes and impurities caused by condensation flower color, light color, the color does not match the kind of phenomenon.

Problem with colored flowers are mainly related to penetrant additives, leveling agents, chelating dispersant, pH value control agents penetrant penetration enough, could easily lead to uneven color dye penetration flowers, such as casual cotton dyeing, cheese dyeing effect, heavy fabric dyeing, penetrant can not be ignored, and some believe only authentic factory penetrant JFC, but did not take into account the cloud point JFC only 38-42 ℃, More than 42 ℃, its penetration force it to play out, will cause quality problems. There leveler with polyester, cotton with wool, nylon used, with all kinds of acrylic leveling agent, and the quality is uneven, leveler selection must take into account the effect of dispersing the dye solubilization, retarding migration effect, Help osmosis or complexation of metal ions in water, and must take into account various factors which PH applicability, foam and other effects on the rate of color. Leveler to improve the color of flowers, color point and so contributed, some plants leveler just solution diffusion agent N, but did not think the proliferation of agents N at a high temperature resistant dyes its unifying role greatly reduced; there the plant selection nonionic surfactants are not suitable, resulting in more than the cloud point nonionic surfactant itself precipitated dye adsorbed from tarry substance or apparatus into the fabric, but cause quality problems. Quality chelating dispersant leveling problems are related, in the current water quality is getting worse, the chelating dispersant leveling should help more attention. pH control problem is a problem of the plant too seriously, pH and some plants are not the same for each cylinder stained, with some plants using different acid substitution of quality, such as containing phosphate, pH phosphate are three ionization there are differences in how to control a uniform pH: pH slip agents using some plants, but not such as to grasp the relationship between the pH and the temperature and time generated between the slip agents, pH control of the question, so that the flower color, the phenomenon of color continue to produce.

6. color point (including white point)
The reason there are many color points generated, such as white spots, may be non-mature cotton is not the cause of the dye, it may be caused by the local soda ash and other solid stick and other reasons not to dye the cloth. Color point is the main reason:
(1) Dye inappropriate choice: dye particles are too large or easy to produce condensed color point;
(2) performing a dye dissolved: not dissolved dye into the fabric from sticking to the dye color point;
(3) water quality is poor: poor water quality caused by dye condensation;
(4) the device without a net: vat of tar-like substance under the swap cause color point;
(5) Auxiliary Reason: added in dyeing auxiliaries sometimes cause the dye to produce color point but agglutination; aids too much foam, foam with a colored dye binding bubbles stick to the fabric to form color point; additives and dyes precipitate combined with the device sticks to the fabric, and agglutinates will turn the device on the color point of the dip caused by the fabric.
