The dendrimers consist of a central core linked to layers of repeating units (generations) and a number of terminal groups. These units are interdependent and create a unique molecular shape. The molecular weight, diameters and terminal group number of different generation PAMAM dendrimers are tabulated in Table 1. Because of their unique structures, dendrimers have a variety of intriguing potential applications like catalyst, sensor, drug delivery, and reaction matrix. The strategies for the design of dendritic macromolecules have convergent, divergent, and double-stage convergent growth methods.

After the finishing process, a special cubic net comprising nano dendirmer and functional inorganic chemicals are form on the textile substrate. This special structure can bring textile with functions of anti-UV irradiation, anti-bacteria etc. The dendrimers with functional inorganic salts offer a way to provide enhanced properties. The dendirmers with —COOH, —NH2, etc terminal groups can bring finished textiles with hydrophilic, anti-bacterial, antistatic etc simultaneously. The dendrimers with alkyl terminal groups provide textile with water proof, good hand feeling, and soil-repellency. The amphiphilic dendrimers and dendimers having siloxane groups finishing bring textiles with good hand feeling and as carrier and phase transfer enhance the dyeing effect of hydrophobic fibres. Also, because of the dendrimers nano structure, it brings textiles with functions of nano material finishing of time enduring, high wash ability while low influence to textiles styles. The terminal groups of dendrimers can be modified to obtain the groups in need to offer versatile function to textile which bring much more difference function to textiles. Besides, because of dendrimers molecules internal voids and channels in the nano sphere, it offers a way for drug or perfume embed and controllable release in finished textiles. The principle of molecular design of the dendrimer is shown in FIG. 3.
  • One finishing liquid preparation and application technology is through sol-gel method. First, nano-dendritic molecules and different function inorganic precursors such as TiO2 and SiO2, are made into sol as finishing liquid. The multifunction finishing liquid is composed of 0.1 wt % dendrimer molecules and 10.0-15.0 wt % functionalized inorganic precursors and distilled water. The finishing process includes impregnation or padding, drying and post curing. The post curing temperature and time are set according to different textiles. After textiles finished a special cubic cross linked net structure will be developed on textile between yarns gap and on yarns surface. The finished textiles can obtain functions of water proof, breathable, anti-static, soil repellency, oil repellency, anti-UV irradiation, anti-bacterial.
