Manufacturing method of dustless cleaning cloth

Abstract

The present invention relates to a production method of dust-free cleaning cloth and its finished product. Said method includes the following steps: 1. adopting extremely fine denier profiled fiber with spade-shaped structure as tissue fibre base material; 2. weving yarn bundle made of said base material into a base cloth; 3. making said base cloth into which a cleaning agent is added into cloth roll; 4. thermosetting said cloth roll; 5. cutting the cloth roll into required size by means of thermal cutter, laser or ultrasonic wave; and 6. finishing to obtain the finished product.

[0002] Dust-free wiping cloth is an indispensable wiping tool in the thin film transistor liquid crystal display (TFT-LCD) panel manufacturing industry, because in the production process of thin film transistor liquid crystal display panels, such as figure 1 , it is often necessary to remove the particles (Particles) 1 on the panel; in addition, if you want to rework after the polarizer 10 is attached, you need to tear off the attached polarizer 10 first, and remove the remaining adhesive on the glass substrate 11 12 is removed, and then a new polarizer 10 can be attached, but no matter whether it is the particles 1 on the panel or the residual adhesive 12, it needs to be wiped with a dust-free cloth dipped in an organic solvent (such as alcohol) , earlier it was used as figure 2 The dust-free wiping cloth made of the traditional round-section fiber 13 is used for wiping, but because it is mainly used for equipment wiping and environmental cleaning and maintenance in the clean room, if it is used to wipe the panel, because the fiber cross-section is circular, each fiber The fineness is about 2 deniers (d.p.f), which cannot effectively remove the stains when wiping the stains, but pushes the stains to the original clean surface. In addition, if image 3 , the rate of gap 14 between circular fibers 13 is low, and the water absorption is 350 milliliters per square meter (ml / m 2 ) below, water marks are likely to remain when wiping, and the industry adopts such as Figure 4 , is a dust-free wiping cloth currently used for wiping thin film transistor liquid crystal display panels, all of which are made of composite fiber 15 [polyethylene terephthalate (PET) + nylon (Nylon)] Because the fiber fineness after splitting is less than 0.3 denier (d.p.f), the cleaning and water absorption properties are excellent, but there are still: 1. After the fiber is reduced and opened, the strength becomes poor, and the rear channel is increased. Difficulty in engineering dust-free cleaning; in addition, when wiping the residual glue stains on the panel, the filaments will be broken to form fiber pollution, which will affect the yield; 2. It is not easy to control the degree of fiber opening and fiber shrinkage, and the manufacturability (manufacturability) Three, the production cost is also far higher than the three shortcomings of the dust-free cloth without fiber opening. Therefore, how to conceive a kind of low manufacturing cost, and the wiper cloth made has high cleaning performance, Water absorption, the manufacturing method and product of the dust-free wiping cloth that does not lose its fiber when wiping, is a topic that can be improved
