High-density microfiber wiping cloth and processing method thereof

Abstract

The invention discloses a high-density microfiber wiping cloth and a processing method thereof. The wiping cloth contains polyester and nylon composite filament, the splitting rate of which is more than 80% and filament number of which is from 0.01 dtex to 0.6 dtex, and the polyester and nylon composite filament is 20%-100% of the wiping cloth in weight. According to JIS1096826IA, the ventilation capacity of the wiping cloth is less than 50cm3 / cm2 / sec. The wiping cloth has the advantages of comfortable feeling, density, high fluid suction and fluid keeping, no harm to surface and high wiping performance.

Description

technical field [0001] The invention relates to a high-density microfiber wiping cloth and a processing method thereof. Background technique [0002] At present, the wiping cloths on the market are divided into ordinary fiber wiping cloths according to the thickness of the fibers. This kind of wiping cloths can only wipe relatively large fibers due to the thicker single filament fineness (generally, the single filament fineness is above 1dtex, and the single filament diameter is above 7 microns). Larger dust particles can only stretch out smaller dirt and oil films, and cannot be wiped off. The monofilament of the superfine fiber wiping cloth is very thin, which can reach about 5 microns or even 2 microns. The wiping performance is good, and it has good wiping properties for dust particles or solvent oil films with dissolved dirt. [0003] However, the general superfine fiber wiping cloth is made of polyester / nylon composite yarn or sea-island polyester yarn through alkali ...

AI Technical Summary

Problems solved by technology

In the end, due to the large reduction rate, the tightness of the cloth will be reduced. Not only is it inconvenient to use because it is too soft, but also when wiping, the dirt or oil film will penetrate through the cloth surface to the reverse side, causing the user or automatic wiping. The pollution on the head may even fall back to the surface being wiped to cause secondary pollution

[0004] Wiping cloths currently on the market, in order to achieve a better degree of compactness, sometimes use a relatively low weight reduction rate for fiber opening, so that although the surface can be fiber-opened, due to the "pockets" formed by the microfiber gaps in the cloth The quantity is not enough and the size is too large, so it is difficult to fix a large amount of dirt. At the same time, because there is no large shrinkage, the fluffiness of the surface is not enough, and it is difficult to take away a large amount of dirt. It takes multiple wipes to achieve better wiping Effect

[0005] Disclosed a kind of polyester nylon composite yarn that adopts twisting as cashmere in Chinese published patent CN1858315A, and polyester is used as ground warp and weft yarn through double organization, alkali reduction, hydrophilic finishing and gluing process to obtain high water absorption, high Wiping cloth with strong wiping performance, but the fiber opening effect of alkali reduction after twisting the composite yarn is difficult to maintain stability. If you want to achieve a better fiber opening effect, you must use a higher weight reduction rate, which will greatly increase The risk of fiber breakage makes the wiping effect of lint falling off during wiping

And after the weight reduction, it is necessary to improve the hand feeling and water absorption through hydrophilic finishing, and the effect of hydrophilic finishing will inevitably decrease after repeated washing

[0006] Another example is that in the Chinese published patent CN101200829A, by adopting a composite yarn with a difference in filament length, and then physically opening the fibers, the fabric becomes dense, and the longer superfine fibers of the yarn length are located on the surface of the wiping surface to improve the wiping effect; Although it is tight, because the high-shrinkage yarn in the composite yarn has a relatively thick single-filament fineness, and the fiber opening rate of the physical method is relatively low, it is easy to cause fiber breakage, which has an impact on the wiping liquid retention performance.
