Carded synthetic leather or similar synthetic leather apron

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

The Japanese enterprise patent can be considered as the material suitable for the manufacture of aprons in China, the requirements and its main working properties-softness, compressibility, elasticity of the compression system, uniformity of the surface progressing state and surface friction coefficient, surface wear resistance , Good oil resistance, and through these technical performance parameters do not change with production time. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.

The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Special equipment for the textile industry on the winder.

As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. Although the aprons made of natural leather have an appropriate softness, good breathability and hygroscopicity, the properties of our products change with time, and at the same time improve the surface existence state to form uniformity, abrasion resistance and resistance. Bad management of berths. When the fibers are drawn, due to the friction of different fibers, the surface of the leather tends to become rough and rough, resulting in sticky flowers, tangled flowers, and the forks are easily polluted by the oil. Sustainability decreased.

Although the synthetic research rubber company has the previous advantages, its softness is poor and the rebound position is large, so it is difficult to spin high-cross yarns. At the same time, there are uneven aprons in our country. Therefore, a method for manufacturing such a synthetic leather aprons is proposed. Carded synthetic leather loops consist of a base layer (orientation layer) and a cover polymer layer (outer layer).

The inner layer is pinhole non-woven fabric. The inner layer is saturated with a porous material mainly composed of polyurethane, and the outer layer is a porous material mainly composed of polyurethane. For example, a pinhole non-woven fabric is made of nylon-polystyrene (50:50) mixed fibers, then soaked in a polyurethane-dimethyl methyl aerogel solution, and coated on the non-woven fabric by wet winding , washed thoroughly with toluene and polystyrene, dried and made into aprons.

It has good flexibility, compression ratio, compression elasticity, surface state uniformity, friction coefficient, abrasion resistance and oil resistance. It can be used for worsted wool spinning to improve spinning quality, and has the advantages of less winding and less end breakage. Another patent describes the use of artificial leather aprons in different situations (29).

The functional polymer chemical substances are filled in the plate composed of a fiber network system, and then the selected leather-like plate is coated with the polymer material material on the research surface, and then the outermost or innermost surface of the plate is applied. Apply a thin layer of hydrophilic organic polymer through a substance (at least on the outermost surface), or coat a thin layer of polymer including a substance on the innermost side, and use such a sheet to make aprons. The shape and structural design of this apron are shown in Figure 2-4 and Figure 2-5. In the group, 1 is the fiber layer of the spatial information network, 2 is the material provided by the ionic molecules filled in the gap of the fiber layer 1, 2 is the macromolecule as the continuous emblem hole in the material 2; 3 is the macromolecule with the Chinese sponge layer structure 3 and a substance, 4 is a hydrophilic reinforcing resin or a hydrophilic level-controlling polymer development substance layer, and 5 is a polymer main substance or a synthetic resin layer.

Japan's patented Yamauchi Rubber Industries proposed a new apron, the upper apron is similar, but also a two-layer structure, the lower layer is a resin thing, suede, candidate, and the middle layer is a complex network of fibers. The lease operation state structure is shown in Figure 12-6 and in Figure 2-7. Figure 2 is hopper 1 due to the fur cap, 2 involves a highly complex fiber layer (thickness 1-8 mm) with a direct network 4 stretchable fibers 3 pinholes (50-400 cells/cm2) with a sea cement Patterns (note the use of leather, natural rubber, synthetic rubber, soft synthetic resin, 0.1-0.5 mm thick) may scratch flexed surfaces, 5 made of synthetic resin sheets or similar can flex the bottom (2,4,5 - adhesives for dry bonding, etc.).
