Abstract

The invention discloses an ultraviolet resistant cold-feeling finishing fabric and a processing method thereof, and application of a silica coated dodecanol microcapsule to ultraviolet resistant cold-feeling finishing fabric. The fabric is characterized in that the inner surface and outer surface of the fabric and the interior of the fabric are distributed with silica coated dodecanol microcapsules. The processing method of the fabric comprises the step that the silica coated dodecanol microcapsules are finished to the fabric by using a padding method. The microcapsule particles have size distribution of 0.2-6 mum; in the padding process, rolling waste rate is 80-90%; a capsule dosage is 40-60g / L; drying conditions include a temperature at 80-100 DEG C and a time of 3-5 min; and baking conditions include a temperature at 140-160 DEG C and a time of 1-2 min. A polyurethane adhesive can be used together with the microcapsules. The fabric has ultraviolet resistant and cold-feeling effects.

Description

technical field [0001] The invention belongs to the technical field of functional fabric processing, and in particular relates to an anti-ultraviolet cold feeling finishing fabric and a processing method, and the application of silicon dioxide-coated lauryl alcohol microcapsules in the anti-ultraviolet cold feeling finishing of fabrics. Background technique [0002] Develop a suitable anti-ultraviolet cooling finishing process, so that dark fabrics used in summer have anti-ultraviolet and cold feeling effects. It can overcome the shortcomings of severe stuffy feeling, easy sweating and uncomfortable wearing when professionals wear dark fabrics in summer. [0003] To achieve the anti-ultraviolet effect of the fabric, the traditional method is to coat the surface of the fabric with a thick coating. Although this achieves the anti-ultraviolet effect, it also affects the air permeability of the fabric and is not suitable for application to clothing fabrics. In addition, to achi...
