Description
Technical Field
The invention relates to a processing method of a cool fiber product, and belongs to the technical field of functional textile processing.
Background
The functional textile not only has the basic functions of wind prevention and warm keeping, but also has other special functions, such as antibiosis, mildew prevention, hydrophobic and oil repellency. In recent years, fiber products with microenvironment temperature regulation functions are popular with consumers, and especially cool fabrics have potential market prospects in summer clothing and home textile processing.
The processing methods of the cool fabric and the fiber product are more, and mainly comprise the following steps: 1) processing the textile by taking cool fibers as raw materials; 2) the fabric product is cool by adopting a specific fabric weave structure; 3) the fiber product is endowed with cool feeling by applying a finishing agent with high heat transfer coefficient and combining a dipping deposition or coating finishing method. The cool fiber is obtained by adding mica sheets into spinning solution and spinning, or directly plating a heat-conducting silver film on the surface of the fiber, and has the advantages of lasting heat-conducting and cool effect and the defect of special requirements on the raw materials of fiber products. The fabric is woven by adopting a specific fabric weave structure to form appearance effects such as meshes, fancy meshes, double-sided vertical strips, concave-convex lattices and the like, and the moisture absorption and cooling feeling of the textile can be improved. The method is simple and feasible, and can be applied to most fiber products, but the method has certain defects, such as poor textile hand feeling caused by a coating method, and poor washing fastness caused by the fact that no adhesive is added for dipping and baking. Therefore, the problem to be solved still exists in the cool fiber product processing at present.
Boron nitride is a crystal composed of equal amounts of boron atoms and nitrogen atoms, has high mechanical strength, wider band gap, excellent chemical stability and higher thermal conductivity coefficient, is an ideal heat conduction material, and has potential application prospect in the development of cool fiber products. On the other hand, unmodified boron nitride has extremely poor compatibility with water, has super-hydrophobicity, and is difficult to form stable hydrogen bonds with water molecules; the nanometer boron nitride can be obtained through ultrasonic treatment or ball milling treatment, the dispersibility of the boron nitride finishing liquid can be improved to a certain extent, but when the nanometer boron nitride is used for impregnating fabrics for cool finishing, the nanometer boron nitride is not firmly combined with fibers, the arrangement of heat-conducting media is not compact, and the excellent heat-conducting property of the nanometer boron nitride is difficult to exert. Therefore, how to effectively improve the dispersing ability and reactivity of the nano boron nitride and promote the combination of the nano boron nitride and the fiber fastness has very important significance.

After the treatment by the above process, the thermal conductivity, the drape coefficient and the burst strength of the samples in example 2 and comparative examples 5 to 8 were measured according to the methods described in the specific embodiments, respectively.

The fibers are not grafted with vinyl, and the heat conductivity coefficient of the grafted samples (the sample in the comparative example 3 and the sample in the comparative example 7) treated by the enzyme catalysis of the vinyl-containing nano boron nitride is obviously increased compared with the former one, which indicates that the enzyme catalysis of the vinyl-containing nano boron nitride is crosslinked with each other but does not further react with the fibers, so that the increase of the heat conductivity coefficient is limited.
In comparative example 4 and comparative example 8, after the samples were treated by the methods described in example 1 and example 2, and then washed with hot water at 60 ℃ for 1 hour and then dried, the results show that the samples have thermal conductivity coefficient similar to that before washing, still have good cool feeling, and the change rate is lower than 4%, which indicates that the samples have high bonding strength and long cool finishing effect. The drape coefficient of the fabric in the above example 1 or example 2 is similar to that in comparative examples 1 to 4 and comparative examples 5 to 8, respectively, indicating that the processing process has less influence on the hand feeling of the fabric.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
