Problems solved by technology

In the dyeing and finishing process, on the one hand, the use of concentrated sulfuric acid will damage the inner wall of the machine cylinder. Experience has proved that if it is used continuously for 2 months, the overflow cylinder will be scrapped; on the other hand, the use of concentrated sulfuric acid also has hidden dangers to the safety of operators.
In addition, what is more important is that when sulfuric acid damages the cortex, it will also damage the core layer, resulting in a significant decrease in the strength of the fabric and unstable use.

Abstract

The invention relates to a splitting agent and a preparation method thereof and discloses a modal fiber napping splitting agent with a skin-core structure and a preparation method of the modal fiber napping splitting agent. The modal fiber napping splitting agent with the skin-core structure is prepared from components in percentage by mass as follows: 20%-40% of organic phosphonic acid, 10%-20% of p-toluenesulfonic acid, 5% of polymeric polyacrylic acid and the balance of deionized water. The modal fiber napping splitting agent has the advantages and effects as follows: not only can the napping splitting purpose be achieved, but also little influence is produced on strength of fabric, and a machine cylinder cannot be damaged.

Description

technical field [0001] The invention relates to a fiber opener and a preparation method thereof, in particular to a sheath-core structure modal fiber raising fiber opener and a preparation method thereof. Background technique [0002] With the innovative development of synthetic fiber technology, the new concept of "fiber opening" comes along. The "fiber opening" of fibers in the dyeing and finishing process involves the opening of chemical composite fibers and the opening of regenerated fibers with skin-core structure. The purpose of fiber opening is to obtain a fabric with a special hand feeling style. [0003] Modal fiber is a high wet modulus viscose fiber developed by Austrian Lenzing Company. The raw material of the fiber is beech wood from Europe. It is made through a special spinning process. There is no pollution in the whole production process and it can be degraded naturally. Its dry strength is close to that of polyester, and its wet strength is stronger than th...
