Method for preparing clean fabrics

Abstract

The invention discloses a method for preparing clean fabrics, which comprises the following steps of: (1) weaving polyester filament yarns serving as ground yarns and poly/nylon filament yarns or polypropylene filament yarns serving as terry yarns into cylindrical grey cloth, wherein the grey cloth consists of base cloth and terry on the single side of the base cloth, and the height of the terry is 0.3 to 0.6cm; (2) opening the grey cloth in an overflow dyeing machine, soaking the grey cloth in an opening washing bath at a bath ratio of 1:70-80 at the temperature of between 70 and 100 DEG C and at normal pressure for 30 to 60 minutes, and drying and sizing the opened grey cloth to form cylindrical smooth grey cloth, wherein the opening washing bath is alkali liquor with the pH value of 13-15; and (3) cutting and sewing the cylindrical smooth grey cloth obtained by the step (2) to obtain the clean fabrics. Compared with the cotton cloth used by soft capsule or pill manufacturers at present, the clean fabrics have the advantages of no hair slip, durability and high liquid absorption capacity.

Description

technical field [0001] The present invention relates to a kind of cleaning fabric which is a wiping product for removing surface adhesive substances such as capsules or dripping pills, such as liquid paraffin, vegetable oil or animal oil, etc., and particularly relates to a preparation method of clean fabric. Background technique [0002] In order to adapt to a fast-paced lifestyle and maintain good health, people need to supplement various nutrients and trace elements needed by the human body. Therefore, a large number of health care products have come out, some of which exist in the form of capsules or dripping pills. Because mineral oil-liquid paraffin has relatively stable chemical properties and is not easy to oxidize, pharmaceutical companies that produce capsules or drop pills often use liquid paraffin as a lubricant during the processing of capsules or drop pills to make finished products Finally, it can make the capsules or dripping pills not easy to stick together,...

Problems solved by technology

Because mineral oil-liquid paraffin has relatively stable chemical properties and is not easy to oxidize, pharmaceutical companies that produce capsules or drop pills often use liquid paraffin as a lubricant during the processing of capsules or drop pills to make finished products Finally, it can make the capsules or dripping pills not easy to stick together, but as a small amount of liquid paraffin on the surface of the finished capsules and dripping pills, it should not be too much, and should be kept at a low level. During the process, most of the liquid paraffin on the surface of the capsules or drop pills is removed, and at the same time when processing different capsules or drop pills, some substances inside the capsules or drop pills will overflow and adhere to the surface of the capsules or drop pills. The surface will also affect the appearance of the capsules or dripping pills. Some of the spilled substances are mostly vegetable oils or animal oils. After a long period of oxidatio
