Problems solved by technology

U.S. Patents US5618610 and US7470656 use corrugated finishing and stripe finishing, but this physical finishing method is likely to cause the wiping cloth to deform after repeated wiping, and the decontamination efficiency decreases instead.
The wiping cloth made in Chinese patent ZL200620100706.6 has low instantaneous water absorption capacity and low water absorption speed

preparation example Construction

[0019] The preparation process of the nonwoven wiping cloth of the present invention mainly includes the following three steps: (1) base cloth preparation; (2) coating finishing; (3) baking process; (5) opening finishing. Especially the formulation of the coating agent and the coating process, and the setting of the opening parameters.

[0020] The wiping cloth referred to in the present invention should meet the requirements of high water and oil absorption, good softness, no crumbs when wiping, and good wear resistance. The present invention adopts the coating process, mainly to solve the problem of shavings caused by the surface hairiness of the needle-punched base cloth during the wiping process, and to improve its instantaneous water and oil absorption performance. However, the coating will sacrifice part of the water and oil absorption rate and softness of the wiping cloth, so the present invention further designs the opening of the wiping cloth. Experimental studies ha...

Embodiment 1

[0037] (1) Selection of base fabric: select needle-punched base fabric mixed with viscose fiber / polyester fiber at 55 / 45, and its weight is 450g / m 2 ;Thickness 3.7mm.

Abstract

The invention belongs to daily necessities, and in particular relates to a method for preparing a non-woven wiping cloth. The method is characterized by comprising the following steps: performing coating finishing on a non-woven base fabric with an acrylate coating agent, wherein 1 liter of coating agent mainly comprises 100 to 800 milliliter of acrylate adhesive, 0.5 to 50 grams of foaming agent, 1 to 30 grams of stabilizer, 0.5 to 40 grams of tackifier, 5 to 80 grams of water absorbent, 1 to 50 grams of cross-linking finishing agent, 10 to 80 milliliter of softener and 200 to 900 milliliter of water; and coating with a scraper is adopted, and the thickness of the coating is 0.05 to 1.5mm; and after the amount of the adhesive is controlled to be between 20 and 250g / m2, performing baking and tapping finishing on the coated material. The vehicle wiping cloth prepared by the process of the invention has good water and oil absorption and relatively good softness, solves the problems of dropping chips, scraping the surface of a vehicle and leaving water marks after wiping which usually appear in a wiping process of an ordinary wiping cloth, and the coating surface and a base fabric have good adhesion.

Description

technical field [0001] The invention belongs to daily necessities, in particular to a method for preparing a nonwoven wiping cloth. Background technique [0002] In the past, people often used old cloths, old towels, etc. as wiping cloths to clean the surface of objects. However, these "wiping cloths" not only have poor wiping effect, but also shed hair and debris, recontaminate the surface, and even scratch objects. At present, a variety of wipes are popular in the market, mainly non-woven fabrics, fabrics, sponges, foam products, artificial or natural deerskin and other products, among which non-woven wipes have the most development prospects. This is mainly because the non-woven fabric has a three-dimensional structure, the fibers are arranged in disorder, and there are many micropores between the fibers. The wipes made are good for liquid absorption, dust removal, and have excellent softness, and the production process is small, the output is large, and the cost is low. ...
