Description
Technical Field
The invention belongs to the technical field of textile assistants, and particularly relates to a softener suitable for N/R roman cloth, a preparation method thereof and a finishing method based on the softener.
Background
Roman cloth is a knitted fabric, also known as Pan Yangde Roman cloth (ponte-de-roma). Roman cloth is a four-way one cycle, the cloth cover is not flat and smooth by common double-sided cloth, and a little irregular cross bar is arranged. The fabric has good longitudinal and latitudinal elasticity, the roman cloth is a very thick and elastic fabric, and has texture as a garment fabric, and the double weaving is natural and light, has good stretchability and little wrinkling, so the roman cloth is commonly used for manufacturing underwear with high air permeability requirement. The most commonly used roman cloth in the market is N/R roman cloth, however, the N/R roman cloth has a relatively obvious disadvantage that as the N/R roman cloth is a fabric blended by nylon and viscose, the nylon fiber has high orientation degree and serious crystallization phenomenon, so that the softness is poor, itching is easy to occur when the fabric is taken next to the skin, and the fabric is combined with an irregular stripe structure, so that the hand feeling is poor. Thus, the prior art has generally used common softeners such as polyethers, amino groups, etc. to finish them, or hydrophilic finishes specific to nylon fabrics, such as those disclosed in CN 107556483B. The conventional general softening agent is difficult to have both high hydrophilicity and expected hand feeling on Roman cloth, and the Roman cloth treated by the softening agent is not washable, so that the hand feeling disappears after multiple times of washing. The hydrophilic finishing agent also has the defects of poor hydrophilic durability and poor hand feeling. Also for this reason, the prior art generally compounds silicone emulsions and hydrophilic polymers into hydrophilic finishes. However, silicone oil gives a good hand feel to the fabric, and at the same time, the hydrophobicity of the fabric is improved, so that the wearing comfort of the fabric is affected. Moreover, sufficient evidence proves that the surface of the fabric finished by the compound hydrophilic finishing agent has the defects of easy contamination, non-hydrophilism, easy static electricity and the like. Meanwhile, there is sufficient evidence that the clothes with static electricity, easy contamination and other problems are harmful to health after being worn for a long time. Thus, there is a need for a suitable softener/finish that addresses the foregoing problems, and also provides a healthy and comfortable wearing environment for the consumer.
