Discussion On Finishing Technology Of Knitted Fabric

People often ask for a small yarn on T-shirts, which comes from consumers and on the other hand is also needed for production.

For example, the modern high-speed circular knitting machine and the warp knitting machine have high requirements for yarn tensile force and elasticity.

What we emphasize here is finishing technology, which plays a very important role in the quality of knitted fabric.

Modern modern finishing machines can provide new, soft, efficient and economical finishing processes to meet people's needs for products.

There are various knitted garments in the market: on the one hand, the knitted fabric with skin feeling, softness of complex fiber and microfiber; on the other hand, there are functional knitwear suitable for different needs.

For knitting technology, today's technology can achieve 50 inches per inch (2.54 centimeters). This product has already appeared in the market, but the highest market share is the warp knitted fabric with 18 to 32 stitches per inch.

Due to various

This single function machine is still visible everywhere, and most of the actual operators of post finishing enterprises take various effective ways to bring the machine into full play.

Multi-function

Modern post processing equipment has been modularized, which can largely satisfy users' individual needs.

Such a device requires complete functions, high performance, strong processing ability, easy operation, process optimization, economical and flexible, and environmental protection requirements.

This multifunctional equipment can handle various products such as fabrics, knitwear and fleece fabrics, and can handle small quantities, even hundreds of meters long fabrics. This kind of equipment has a great market prospect.

New technologies emerge in endlessly.

Lafer, based in Schio, Italy, has introduced a device that can be used for fleece and fur lining for sportswear and winter knitwear.

Recently, at the Asian Textile Machinery Exhibition (ITMA) held in Singapore, the company launched a slogan of "accelerated finishing" to promote the equipment.

The super soft raising machine (UtraSoft-T) introduced a prototype two years ago to handle circular woven fabrics.

The company has claimed that the patent stretches and special flanners can even handle the velvet structure.

It has been 25 years since Lindau, a Lindau in Germany, studied the processing of circular woven fabrics (Lindauer-Dornier).

The machine introduced by the company uses a flexible circular fabric stretper for singeing, bleaching and mercerizing to avoid wrinkling during processing.

The latest reform is to replace the rubber fixed roller and symmetrical roller with non-contact magnetic control.

According to the company, due to the improvement of this technology, the quality problems of knitted fabric due to pressure and wire drawing can be reduced.

In order to save energy and cost in the wet process (including heat setting and drying process) of superfine modal (Micromodal) and elastic blended fabric, it is necessary to ensure the effective humidity value.

Through the new cylinder type rolling mill (EcoSqueeze), the fabric will no longer appear indentation, weft and other defects, fully meet the quality requirements of the product.

Some companies are committed to the study of drying technology.

Brook Br ckner Trockentechnik, which is located in Leonberg, Germany, developed special processing methods for circular knitting machines and warp knitted fabrics. The concept of flat stretch was proposed and named PowerLine.

This technology utilizes a complex system to control the direction of inlet and outlet air flow so as to optimize the drying process.

At the same time, it is applied to elastic knitted fabric combined with feeding mechanism, stretching before knitting.

According to the requirements of different processes, the degree of heating can be controlled in the drying process, and the residual moisture is controlled accordingly, so that the phenomenon of drying is avoided.

In the summer of 2004, the Fuji (Monforts) company at M? Nchengladbach, Germany, began to certify and issue Monforized quality certification labels. Monforts launched a series of quality standards for a series of fluffy dryer, stretch dryers, continuous dyeing machines and anti shrinkage finishing machines.

The company said that Fuji launched the "MONFORIZED" certification, which aims to help textile buyers distinguish the quality of printing and dyeing and ironing merchants. For printing and dyeing and ironing merchants, they can prove that they are equipped with modern equipment, and the equipment is good in performance, and can produce high standard quality fabrics.

The "MONFORIZED" certification will only be issued to those textile manufacturers that use Fuji modern equipment and maintain the level to Fuji standard.

The validity period is 2 years. After the expiry, the manufacturer will wait until the equipment passes the test of Fuji technician.

According to Fuji, according to Fuji, more than 20 international textile manufacturers have obtained the certification after the "MONFORIZED" certification came out, including 10 Chinese companies, such as Jiangsu red willow sheet group company (Jiangyin sheet factory), Shanghai Huayuan home textile (Group) Limited by Share Ltd, Kaiping Ben Da textile and so on.

In addition, in Pakistan, Turkey, Germany, Italy and Belgium, fabric manufacturers have also been granted "MONFORIZED" certification.

According to Hongkong Fongs (Li Xin), its ECO-8 multi ring loose dyeing machine (Multi Ropesoft) can not only dye the woven and knitted fabrics, but also greatly reduce the production cost.

The company said that the internal pmission system of the machine has been optimized in a whole way, and only a small amount of water, energy and chemicals can be used to improve the dyeing effect.

The pmission system also has an expansion device to prevent scratches and folds.

The inner part is coated with a layer of polytetrafluoroethylene (PTFE), so the fabric can be passed smoothly.

Future development

Just as architects are concerned about building blocks, the world's leading textile chemicals manufacturers are concerned about the systematic research of chemical substances, so that chemicals can match each other, mainly to simplify the process of dyeing and finishing.

Product recognition is one aspect of consumers, and manufacturers are constantly thinking about users.

Sustainable development is the concern of all, as well as the safety in the production process, the continuous optimization of production process and the reduction of costs.

In this process, the purchase of cheap finishing products is not the main thing. The important thing is that the consumption of water and energy and the disposal of waste will greatly reduce the profit margins of the products.

At the same time, we should also consider the problems of high permeability, extraction of chemical substances and requirements for waste utilization.

Hartmut Hasse, general manager of Basf Inc (BASF), the world's most famous textile finishing chemical company in Ludwigshafen, Laifa, Germany, said recently at the Singapore textile machinery exhibition. "We are using modern technology to provide consumers with new and powerful products.

Strive to provide consumers with a better choice in terms of quality, efficiency and environmental protection.
