[0044] (c) Under stirring, add 1 / 3 weight of polymer monomer mixture A and 1 / 3 weight of N-methylol acrylamide ...

Embodiment 2

[0047] A method for preparing a burnt-out printed flocked fabric, comprising electrostatic flocking and burnt-out printing, the specific steps are as follows:

[0048] (1), electrostatic flocking process

[0049] First with the polyacrylate adhesive emulsion that embodiment 1 prepares: thickener HIT: the weight ratio of polyisocyanate=100: 2: 2 prepares flocking glue, then flocking glue is with 240g / m 2 The amount of glue applied is scraped on the spandex or polyester knitted fabric, and then the mixed fluff made of 1.5D×0.5mm nylon fluff and 1.0D×0.6mm viscose fluff is carried out under the conditions of voltage 50kV and pole distance 10cm. Flocking. Finally, pre-bake the flocking fabric at 85°C for 5 minutes and bake at 155°C for 5 minutes; then brush the bristles and set the shape.

[0050] (2), burnt-out printing process

[0051] First, the original paste is made according to the weight ratio of paste A9: water = 10 parts: 100 parts, and 12 parts by weight of aluminum sulf...

Abstract

The invention provides an etching printed flocked fabric, which comprises a textile base cloth layer, a mixed flock layer and a binding agent for fixing the textile base cloth layer together with the mixed flock layer, wherein, the binding agent is polyacrylate binding agent. The invention further provides the process for manufacturing the etching printed flocked fabric. The advantages of the etching printed flocked fabric and its manufacturing process in the invention lies in that: it achieves the printed pattern with obscure and hollow cutting effects, bright and colorful appearance of finished product and high fastness.

Description

technical field [0001] The invention relates to the fields of clothing and textiles, in particular to a burnt-out printed flocked fabric and a preparation method thereof. Background technique [0002] Electrostatic flocking is to use high-voltage electrostatic field to make the processed short fleece vertically implanted on the base cloth coated with adhesive along the power line. Flocking products are colorful, three-dimensional, soft to the touch, and have multiple functions such as sound absorption, waterproof, and warmth retention, so they can be used in decoration, clothing, arts and crafts, and product packaging industries. [0003] Burn-out printing is to print acid carbonized pulp patterns on flocked fabrics composed of different acid-resistant fluffs to destroy and dissolve one or several fluffs, so as to obtain vague and hollow carving patterns. This technology improves the appearance quality of flocking products, expands the design ideas of flocking products, and...
