Abstract

The invention discloses a thermal transfer printing method for a waterproof moisture-permeable nanofiber membrane, which comprises the steps: printing patterns on a transfer printing medium; transferring the patterns from the transfer medium to a waterproof moisture-permeable nanofiber membrane; and separating the transfer printing medium and the waterproof moisture-permeable nanofiber membrane after printing the patterns. The nanofiber membrane subjected to transfer printing has good light fastness, water fastness and dry-wet rubbing fastness, as well as good mechanical properties, air permeability, moisture permeability, water resistance and the like. At the premise that waterproof and moisture-permeable performances of the waterproof moisture-permeable nanofiber membrane are not greatlychanged, the dry rubbing fastness of the waterproof moisture-permeable nanofiber membrane after transfer printing reaches grade 3-4, with wet rubbing fastness reaching grade 3-4, water fastness reaching grade 5, and light fastness reaching grade 4-5. The tensile strength is increased by 56.6% on average; the hydrostatic pressure resistance is increased by 32% on average; and the moisture permeability is increased by 167.4% on average.

Description

technical field [0001] The invention belongs to the field of green textile printing and dyeing, can solve the problem that the current waterproof and moisture-permeable nanofiber membrane is difficult to color, has no pollution, and meets the requirements of environmental protection. Specifically, it is a new product that uses thermal transfer printing technology to print waterproof and moisture-permeable nanofiber membranes to obtain certain patterns. Background technique [0002] Waterproof and moisture-permeable nanofiber membrane, the main components are PVDF and PU. obtained by electrospinning. The nanofiber membrane fabric prepared by electrospinning not only has good waterproof performance, but also has good moisture permeability and certain strength. It has good application prospects in sunscreen clothing and sunscreen T-shirts. However, because the waterproof and moisture-permeable nanofiber membrane has good waterproof performance, it is difficult to color, and t...
