Technical Field

The application relates to a textile hand feeling finishing agent technology, in particular to a terylene fluffy hydrophilic film.

Background

Soft finishing is an important after-finishing process in printing and dyeing processing. During the processing of the textile, the hand feeling of the textile becomes rough after being treated for many times, and the common synthetic fiber fabrics are worse, especially the superfine fiber fabrics. In order to make the fabric have soft, smooth and comfortable hand feeling, the fabric needs to be finished, and the finishing is widely performed by using a softening agent at present.

Softeners are a class of chemicals that change the static and dynamic coefficients of friction of the fibers. When the static friction coefficient is changed, the hand feeling is smooth to touch and is easy to move on the fiber or the fabric. When the dynamic friction coefficient is changed, the fine structures between the fibers are easy to move mutually, namely the fibers or the fabric is easy to deform, and the combined feeling of the fibers and the fabric is soft. Therefore, the fabric softener is an important textile auxiliary. At present, the softening agents commonly used in the printing and dyeing industry are mainly: silicone emulsion type softeners, film type softeners, wax emulsion type softeners and the like.

The film is used in large amount in the finishing process after printing and dyeing due to low price. The soft sheet plays an essential important role in improving the product quality and the added value of the textile, can endow the textile with various special styles and functions such as softness, fluffiness, elasticity, smoothness, antistatic property, antibiosis, ozone resistance and the like, can improve a dyeing and finishing process, and plays roles in saving energy and reducing processing cost. The film is crucial to promote the overall level of the textile industry and its role in the textile industry chain.

The hand feeling of the film products is good, but the film products are not hydrophilic. The polyester fabric has the advantages of high strength, wear resistance, good rebound resilience, low cost and the like, and is widely used as a textile fabric. However, the polyester structure has no polar group, so that the polyester fabric has poor hydrophilicity and low moisture regain (standard moisture regain is 0.4%), thereby affecting the wearability of the polyester fabric. Therefore, the terylene bulky hydrophilic film with simple preparation process, low cost, fluffy softness and good hydrophilic performance is in urgent need.
