Abstract

The invention discloses a thermal transfer printing method for a waterproof and moisture-permeable nanofiber film, which comprises the following steps: printing a pattern on a transfer printing medium; transferring the pattern from the transfer medium to the waterproof and moisture-permeable nanofiber film; transferring the printing Separation of the medium and the waterproof and moisture-permeable nanofiber membrane after printing the pattern. The nanofiber film after transfer printing has good light fastness, water fastness and dry and wet rubbing fastness; good mechanical properties, air permeability, moisture permeability, waterproof performance, etc. The invention realizes that under the premise that the waterproof and moisture-permeable nanofiber membrane's waterproof and moisture-permeable performance does not change greatly, after transfer printing, the dry rubbing fastness of the waterproof and moisture-permeable nanofiber membrane printed product is grade 3-4, The wet rubbing fastness is grade 3-4, the water fastness is grade 5, and the light fastness is grade 4-5. The tensile strength is increased by an average of 56.6%; the hydrostatic pressure resistance is increased by an average of 32%, and the moisture permeability is increased by an average of 167.4%.

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...
