Problems solved by technology

[0004] Compared with the washing machine washing method, the hand washing method can carry out meticulous cleaning according to the decontamination status and the type of the object to be cleaned, but on the other hand, for the laundry person, it is also accompanied by physical and mental stress. fatigue
Especially the "rubbing" method of rubbing between the objects to be cleaned, although this method is easy to apply mechanical force to the parts to be cleaned, it is one of the most natural hand washing methods, but long hours of labor will become a burden for the laundry person
[0005] In addition, microscopic observation of cloth and other objects to be cleaned is not smooth, in fact, resistance will be generated when they are rubbed against each other
This kind of resistance will make people feel uncomfortable elements such as "roughness" and "friction" of the object to be cleaned, and the scrubbing action will also cause physical exertion, further increasing the burden on the body
In addition, the local friction generated during scrubbing will cause hand scratches and scratches, and cause fiber wear on the cleaned object, that is, "fabric damage" will occur
Fiber damage not only shortens the durability of the garment, but also acts as a factor that increases soil adhesion, further increasing the physical strain required for washing
[0006] In addition, this frictional resistance will also cause fiber damage, deformation, etc. due to mechanical forces such as stirring in the washing machine.
[0007] On the other hand, the technical development at this stage mainly focuses on improving the cleaning performance of detergents, preventing the recontamination of clothing on the object to be cleaned, etc. "how to remove the attached dirt from the object to be cleaned", or Bring softness to the clothes after washing and other aspects such as "how to complete the treatment after washing" (for example, refer to Patent Documents 1, 2, 3, 4), but so far, hand washing as described above has not been considered The uncomfortable elements and physical loads that occur during the process, that is, "the mental and physical burden of the scrubber", and the development of technologies that focus on improving this situation

Abstract

The present invention relates to a method for improving the smoothness of objects to be cleaned in the washing liquid by allowing an organic polymer with stringiness to exist in the washing liquid during washing; liquid, or use a washing solution diluted with water to more than 1 time and less than or equal to 1000 times, and perform the hand-washing washing process of the cleaned object; contain more than 0.1% by weight of an average molecular weight of 1.5 million or more with stringiness Detergent compositions of organic polymers; laundry detergent compositions containing polymers with an average molecular weight of more than 500,000 and more than 60 mol% of structural monomers having sulfonic acid groups or their salt-type groups, or sulfuric acid groups or their salt-type groups things. The detergent compositions of the present invention are particularly suitable for hand washing.

Description

technical field [0001] The present invention relates to a method for improving the smoothness of an object to be cleaned, a hand washing method, a detergent composition, a laundry detergent composition, and a smoothness improving agent. [0002] In addition, the present invention also relates to a washing method using the above-mentioned detergent composition, laundry detergent composition or smoothness improving agent. Background technique [0003] Washing methods are roughly divided into two types: hand washing and washing machine washing. In recent years, with the popularization of washing machines, there is an increasing trend of using washing machines for machine washing. However, due to the considerations of decontamination and economic benefits, people still use hand washing. [0004] Compared with the washing machine washing method, the hand washing method can carry out meticulous cleaning according to the decontamination status and the type of the object to be clea...
