With the winter season coming, the temperature is getting colder and it's more challenging for hipsters to wear. Shaker down is definitely a more "alternative" option than puffy down jackets and heavy coats. In addition to the advantages of heat preservation, air permeability and weight, the shaker fleece has been improved in the last two years on the model and color matching, and has been reactivated the fashion DNA. The perfect balance of "grace and temperature", and to meet the needs of the current young people to "fold" and other personalized collocation, it can be said that shaker velvet has become an essential piece of clothing in our winter wardrobe.

So what exactly is shaker fleece? The following small series for you to introduce the basic knowledge of shaking grain velvet.


First, the definition of shaker fleece


Definition 1.

Polar fleece (also known as sheep pile) is a kind of knitting fabric, woven circle machine, woven fabric after dyeing first, after again hair, combing, and anti-pilling finishing of wool processing technology, positive napped fabrics, anti-pilling fluffy dense and difficult to shed, pilling, opposite thin thin hair, well-balanced, hairs short, texture clear, soft, good elasticity.


Characteristics of 2.

Its ingredients are generally all polyester, feel soft, winter is the first choice of cold products. In addition, shaking fleece can also be combined with any other fabric to make the cold effect better (shaking fleece and shaking fleece compound, shaking fleece and denim compound, shaking fleece and lamb compound, shaking fleece and mesh fabric compound with waterproof breathable film and so on).


Classification of 3.

4. The application

Fleece is mainly used to make the lining of clothes (generally choose polyester 150D96F fleece, "D" thickness, "F" root number) made of bedding, carpet, coat, jacket, vest, windbreaker, clothing logo, gloves, scarves, hats, pillows, cushions, shoes and toys, etc.



Second, the development process of shaking grain fleece

Shaker fleece production in Taiwan in the early 1990s, the mid-1990s, Fujian quanzhou area also began to produce shaker fleece, are generally Taiwan technology. Later in Zhejiang, Changshu, Wuxi and Changzhou areas also began to produce shaker fleece. The quality of shaker fleece in Jiangsu is better, and the price of shaker fleece in Zhejiang is lower. Shaker fleece has plain color and printing, plain color shaker fleece according to different personal requirements, can be divided into strip shaker fleece, embossing shaker fleece, jacquard shaker fleece, etc. According to the different printing materials, there are more than 200 varieties of printing, such as penetration printing, glue printing and transfer printing color strip. This fabric pattern is novel and unique, colorful, natural and smooth, favored by people from all walks of life.

Three, the production process of shaking grain fleece

1. Technological process

White base inspection - dyeing - type soft reservation - finishing - drying - napping - combing, shearing, high temperature gas steam curly anti-pilling - shape - - inspection of warehouse

2. Production of grey cloth

Sd-60 and SD-60A single - side wool - winding machines produced by Taiwan Sanda company are generally used.

3. The dyeing

The high temperature and high pressure overflow jet dyeing machine is generally used, which can not only adjust its running speed according to the fabric type structure, but also automatically prompt feeding and automatically control the temperature rise and fall, so as to better ensure its dyeing quality. After dyeing, the fabric needs to be dewatered by a centrifugal dehydrator and dissected by a high-speed loom.

4. Drying and setting equipment after setting

These two kinds of process equipment are using eight zone hot air needle plate tensioning machine, but the drying of the scheduled type need rolling and then finalize do not need. This equipment is a kind of combined machine, which can be rolled, drying, drawing and shaping at one time. It is composed of preparation part (rolling), heating part and cooling part. The model is KST10, the power is 380V, 50HZ, according to the different weight of the fabric, the setting parameters are different, such as the weight of the fabric is 285, the general heating parameters are set to 158 degrees, the cloth speed is 29m/min.

5. Terry

Shaking grain generally adopts frequency conversion type raising machine, such as MB335B raising machine of Yingyou Spinning Machine, Taiwan East Asia Gear machinery Factory, etc. Its characteristic is that the operation mode is mechanical change gear, driven by gear and chain, raising roller 24, diameter 62mm. Under normal circumstances, one line is equipped with 6-7 fuelling machines, two of which are anti-fuelling and the other several are positive fuelling. The cloth walking speed is generally set as 18m/min.

6. The bristles

Brush machine generally adopts digital brush machine, touch screen control, belt drive, high production efficiency, for example: SME485 and SME485C series brush machine in Eagle Spinning machine, under normal circumstances, three production lines can be configured with two brush once on the front side, not on the back side, usually the working parameters are set as follows: Cloth walking speed 35m/min, cylinder speed 80-110rpm (depending on the cloth), tension set at 1.00, 1.01, 1.03, 1.04, brush force depends on the weight of the fabric, usually 15-20 g, 8-15 g.

7. Shearing

Under normal circumstances, shearing once can meet the requirements, shearing machine is composed of round knife, flat knife and bracket, such as: Yingyou machine MB314 shearing machine (Germany imported round flat blade), Changzhou Tonghuang shearing machine, Changzhou constant spinning shearing machine, Shanghai Chi Rong shearing machine, under normal circumstances, a production line equipped with one. The shearing quality directly affects the quality of shaking grain, while the length of shearing affects the style of products. In order to reduce the cost and minimize the loss of shearing, as long as the brush out of the hair and the length of the hair cut off, so that the face hair neat. Process parameters: the cloth speed is generally 30-40m/min, the rotary speed of the circular knife is 1000rpm, and the tension is moderate.

8. Anti-pilling

The process is mainly completed by shaking machine, which is composed of air jet device, blower device and shaking host frame. The operation mode is touch screen control, and it can operate automatically as long as various required working parameters are set. But not all products are used in the above equipment, such as plush, ant cloth only need to brush, do not shake do not cut. According to different products, choose different finishing equipment. General ordinary fabric shaking time control in 20 minutes, temperature control in 46-60 degrees, heating timing 20 minutes, cooling timing 20 minutes, steam timing 20 minutes, according to different materials, set parameters are different. After shaking the grain, you need to take back the twisting cloth, such as shaoxing Xin Tian Jin knitting equipped with shaoxing jing chuang take back the twisting cloth machine.

9. To finalize the design

The products need to be finalized before playing, such as Zhejiang Tianshi company used Taiwan Force gen Bao molding machine, Shaoxing jianzhong zhongshan Huangji molding machine. If the customer has requirements on the density of the fabric, it is necessary to do a single set of back brush treatment before shaping.

10. Volume

General winding machine in the frame under a set of telescopic rise and fall ability of winding device, winding device arm or long or short or wide or narrow, dc motor drive sprocket, chain drive mechanism. The rolling cart is composed of frame, wheel, top wheel, roller bearing seat and so on. Its main function is to take away the cloth rolled by the rolling machine for printing and dyeing. At present, customers use the winding machine shaoxing Jin Long, Shaoxing sanlian, Shanghai Deshi Kang, etc., such as: Shaoxing shen Hui ironing light used shaoxing Guangxing test cloth rolling machine.

11. Outbound

The products can go out for sale after rolling inspection.

Four, shaking fleece products

Understand the above shaker nap related knowledge, a lot of people will want to shaker nap products is not the same? It is wrong to think so. In fact, the enterprises producing fleece fabric are producing more creative products through continuous innovation.
