Embodiment 1

[0029] (a) The following monomers

[0030] Butyl acrylate 120g

[0031] Methyl methacrylate 18g

[0032] Acrylic 6g

[0033] Styrene 15g

[0034] Place it in a 500ml reactor and stir evenly to form a polymer monomer mixture A. Dissolve 5g of N-methylolacrylamide with 75g of deionized water to form a solution for later use.

[0035] (b) Combine the following components

[0036] Fatty alcohol polyoxyethylene ether (10) 3.5g

[0037] Emulsifier OS 2.3g

[0038] Alkylphenol polyoxyethylene ether (30) 3.5g

[0039] Polyethylene glycol (molecular weight 400) 2g

[0040] Sodium lauryl sulfate 2.3g

[0041] Glycerin 1g

[0042] Deionized water 250g

[0043] Place it in a 500ml glass, stir and dissolve at 50°C for 40 minutes to form a stable emulsifier aqueous solution B. Dissolve 0.45g ammonium persulfate with 75g deionized water to form a solution for later use.

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

Embodiment 2

[0047] A preparation method of burnt-out printed flocking fabric includes electrostatic flocking and burnt-out printing. The specific steps are as follows:

[0048] (1) Electrostatic flocking process

[0049] First, the polyacrylate adhesive emulsion prepared in Example 1: thickener HIT: polyisocyanate = 100: 2: 2 weight ratio to prepare flocking glue, and then the flocking glue is 240g / m 2The amount of glue applied is scraped on the spandex or polyester knitted fabric, and then mixed with 1.5D×0.5mm nylon fleece and 1.0D×0.6mm viscose fleece under the conditions of voltage 50kV and pole distance 10cm Flocking, and finally pre-baking the flocked fabric at 85°C for 5 minutes and 155°C for 5 minutes; then brushing and setting.

[0050] (2) Burnt-out printing process

[0051] First, prepare the original paste according to the weight ratio of paste A9: water = 10 parts: 100 parts, add 12 parts by weight of aluminum sulfate to the original paste to prepare the carbonized slurry, and th...

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 burnt-out printed flocking fabrics and a preparation method thereof. Background technique [0002] Electrostatic flocking is to use high-voltage electrostatic field to implant the processed short fleece on the base cloth coated with adhesive vertically along the power line. Flocking products are rich and colorful, strong in three-dimensional, soft in hand, and have multiple functions such as sound absorption, waterproof and warmth, so they can be used in decoration, clothing, arts and crafts and product packaging industries. [0003] Burnt-out printing is to print acid carbonized pulp patterns on flocked fabrics composed of different acid-resistant fluffs to destroy and dissolve one or more of the fluffs, thereby obtaining a vague, hollow engraving effect. This technology improves the appearance quality of flocking products and expands the design ideas of flocking products. Its p...
