1. sizing. According to the properties of products and substrates, different properties of adhesives are selected. Waterborne polyurethane adhesives or acrylic adhesives can be selected according to different materials and properties. For example, rubber, plastics, steel, glass, wood and so on, the adhesive fastness is mainly considered. Clothing should be considered not only for its fastness to washing, but also for its soft handle, breathability and moisture permeability. The viscosity is too small, the fuzz on the plant may tilt, and the viscosity is too large, which will hinder the implant depth and reduce the strength. A large amount of coating will cause poor touch and prolong drying time. The coating will be less and the rubbing fastness will be reduced. The proper viscosity and coating amount can be adjusted to ensure the quality of flocking.

上浆方式目前主要采用辊筒法和刮刀法。对于植花(局部植绒),则采用圆网或平网印浆法对花纹部印浆,要求均匀、边界清晰,不能有起泡或空白点,植绒后形成植绒花纹。

The main way of sizing is roller and scraper. For planting flowers (local flocking), a circular or flat screen printing method is used for the printing of the pattern, which requires a uniform and clear boundary, and no bubbles or blank spots, and the flocking pattern is formed after the flocking.

2.植绒。植绒方式主要有提升式、下落式、侧植式和上下拼植式四种。提升式:绒毛在输送带上进入电场,在静电作用下绒毛自下而上飞升插入底材粘合涂层中粘合剂中。提升法被植物在上方,下落法加工物在下方。提升法需要两条输送装置,即被加工物输送和绒毛输送,结构复杂,传送时张力较大,若强力不大的织物就很难加工。不连续生产,则提升法比较好,因为绒毛在静电场作用下一部分植入粘合剂中,多余的绒毛会自然落下,植绒表面浮绒较少。下落法则另加一个吸绒装置,将在绒面的浮绒吸去,目前多数植绒机均采用下落式。侧植式适用于片块状物体的植绒,提升下落拼植法适用于线状物体的植绒。

2. flocking. There are four ways of flocking: lifting, falling, side planting and up and down. Lifting type: the fluff enters the electric field on the conveyor belt. Under the action of electrostatic force, the fuzz goes up from bottom to top into the adhesive of the substrate adhesive coating. The lifting method is placed above and below the processing plant. The lifting method requires two conveying devices, namely, the conveying of the processed material and the conveying of the wool. The structure is complex, and the tension is large when conveying. In discontinuous production, the lifting method is better, because the fluff is implanted in the adhesive under the action of the electrostatic field. The excess fluff will fall naturally, and the surface of the flocking is less. The falling rule plus a suction device will absorb the floating fleece on the suede, and most of the flocking machines are used at the present time. The side planting type is suitable for flocking of block like objects, and the lifting and falling planting method is suitable for flocking of linear objects.

植绒室的心脏是高压静电发生器。通常要求直流电压达20-200千瓦,两电极之间的距离按公式E二V/H可求得,式中:E为电场强度(v/m)；v为极板电压(v)；H为极板短离(m),一般为10厘米以内,电场强度1-5千瓦/厘米,绒毛以100-200厘米/秒的速度垂直插入底材表面的粘合剂中。为了确保车速较快时的植绒质量，可采用多套静电发生器,或者增加打击振动装置,来补充静电力的不足。

The heart of the flocking room is a high voltage electrostatic generator. The DC voltage is usually required to be 20-200 kilowatts, the distance between the two electrodes is obtained by formula E two V/H, in the formula: E is the electric field strength (v/m); V is the plate voltage (V); H is the polar plate short (m), generally within 10 cm, the electric field strength is 1-5 kW / cm, and the fluff is vertically inserted into the adhesive on the surface of the bottom material at 100-200 cm / sec. In order to ensure the quality of flocking when the speed is fast, a number of electrostatic generators can be used, or additional vibration striking devices should be added to supplement the shortage of static electricity.

3.热固。植绒完毕后需进行热处理,以使绒毛、粘合剂和底材牢固结合。一般都有两个阶段:预烘和焙烘,具体视粘合剂种类而定。加热方式也有多种,通常采用热风循环方式较好,既可达到粘合剂交联温度,又能使粘合剂中水分尽快脱离。烘燥温度还应注意到底材性质,防止材质在较高温度下会变形。热处理在烘箱中完成,其质量对植绒牢度影响较大。为了确保热处理的温度和时间,若车速较快时,应适当加长烘箱长度。

3. thermosetting. After the flocking is finished, heat treatment is necessary to make the wool, adhesive and substrate firmly combined. Generally, there are two stages: pre drying and baking, depending on the type of adhesive. There are also many ways of heating. Generally, the hot air circulation method is better, which can not only achieve the crosslinking temperature of the binder, but also make the moisture in the adhesive as soon as possible. Drying temperature should also pay attention to the properties of the material to prevent deformation of the material at higher temperature. Heat treatment is completed in oven, and its quality has a great influence on flocking fastness. In order to ensure the temperature and time of heat treatment, the oven length should be lengthened properly if the speed is fast.

4.刷毛。在植绒后虽吸去浮绒,但在间隙中还有残余绒毛,一般采用毛刷逆底材运动走向的方式,进行一次刷毛清洗。也有采用机械拍打、吹风等方式相结合进行处理,则效果更佳。如不需后整理加工,则刷毛后即可得到成品。

4. brush hair. After flocking, though it suck floating fleece, there are still residual villi in the gap. Generally, brush brush is used to reverse the movement of the base material to carry out a brush cleaning. There is also a combination of mechanical flapping and blow drying to achieve better results. If no finishing is needed, the finished product can be obtained after bristling.

   5.后整理.后整理的目的是锦上添花和提高产品附加值。例如:全面植绒(又称满地植绒)虽然赋予产品绒的风格,但美中不足色彩单一,于是采用印花(或转移印花)加工方法,印上各种彩色图案,而成为印花植绒产品；通过轧辊热压(轧辊上刻有凸型图案)压花(轧花),使局部绒毛在高温下变形固化,成为轧花植绒产品;利用喷管上若干小孔,喷出过热蒸汽使绒毛受热变形,且喷汽口横向有规则地往复与织物纵向直线运动,形成了一定形状的几何图案,成为喷花植绒产品;利用磨毛工艺,将植绒织物表面绒毛磨细,达到仿魔皮绒效果;采用化学处理法(仅对复合纤维)将植绒产品浸渍在溶液中,溶去“海”部分纤维,形成仿桃皮绒、仿丝绒产品,等等。以上仅列举了一部分后整理方法。总的来说目前后整理方法很多,但开发力度还不够,有很多课题需要我们探索研究。

After finishing 5., the purpose of finishing is to add icing on the cake and improve the added value of products. For example, the full flocking (also called full ground flocking), although endowed with the style of the product, has a single color in the United States, so the printing (or transfer printing) processing method is used to print various color patterns and become printed flocking products; the hot pressing of the rolls (the roll is engraved with a convex pattern) embossed (ginning) to make the local villi deformed at high temperature. It becomes a floral flocking product; using a number of small holes on the nozzle and spraying superheated steam to heat the fluff, and the nozzle has a regular reciprocating movement between the fabric and the fabric, forming a geometric pattern of a certain shape and becoming a floral flocking product; using the grinding process, the surface villi of the flocking fabric will be grinded to imitate the magic skin effect. Fruit; chemical treatment (only for composite fiber) to impregnate the flocking products in the solution, dissolve the "sea" part of the fiber, form the imitation peach skin, imitation velvet products, and so on. Only a part of the finishing method is listed above. Generally speaking, there are many ways of finishing now, but the development is not enough. There are many subjects that we need to explore.
