preparation example Construction

[0041] A method for preparing a microcapsule printed fabric for improving hand feeling, comprising the following steps:

[0042] (1) Preparation of low-crosslinked shell microcapsules;

[0043] (2) mixing the above-mentioned low-crosslinked shell microcapsules and a compound emulsifier to obtain a printing paste;

[0044] (3) Printing the above-mentioned printing paste to obtain a microcapsule printed fabric with improved handle.

[0045] The preparation of low cross-linked shell microcapsules comprises the following steps:

[0046] a. Add oil-soluble core material, water and emulsifier into high shear emulsifier to form O / W emulsion A;

[0047] b. Add oily wall material polymer monomer, water and emulsifier into a high shear emulsifier to form O / W emulsion B1, and prepare water-soluble wall material polymer monomer as solution B2;

[0048] c. Add B1 and B2 dropwise to A, the dropping rate is the system mass increase rate, 0.5-2.8%wt per minute;

[0049] d. Adding a crossl...

[0069] Such as figure 1 As shown, in this example, the SEM photograph of the phase change microcapsule with a phase change temperature of 28°C is used. The preparation of the low-crosslinked shell microcapsules comprises the following steps:

[0070] a. Form O / W emulsion A with octadecane, water and OP-10;

[0071] b. Form O / W emulsion B1 with isophorone diisocyanate and water, OP-10;

[0072] c. Add B1 dropwise to A, and the drop rate is 1.2%-2.2%wt per minute for the system mass increase rate;

[0073] d. Add cross-linking agent polyether amine, the amount of cross-linking agent is 4.2%-8.5%wt of the mass ratio of oily wall material polymer monomer; %-2.2%wt;

[0074] e. Insulate at 50-80°C for 3-8 hours to form a polymer at the oil-water interface to obtain the low-crosslinked shell microcapsules.

[0075] The particle size test result of a kind of low cross-linked shell microcapsule of gained is as follows figure 2 As shown, the D50 is 2.078 microns, and the maximum...

Embodiment 2

[0087] In this example shea butter microcapsules are used.

[0088] The preparation of the low-crosslinked shell microcapsules comprises the following steps:

[0089] a. Shea butter, water and polyethylene-maleic anhydride are hydrolyzed sodium salt to form O / W emulsion A;

[0090] b. Hydrolyze ethylene glycol dimethacrylate, crosslinking agent trimethylolpropane triacrylate and water, polyethylene-maleic anhydride sodium salt to form O / W emulsion B1;

[0091] c. Add B1 dropwise to A, and the drop rate is 0.5%-1.8%wt per minute for the system mass increase rate;

[0092]d. In this example, after the crosslinking agent trimethylolpropane triacrylate is mixed with the polymer monomer, emulsion B1 is formed together, and the amount of the crosslinking agent is 2.2% to the mass ratio of the oily wall material polymer monomer 10.5%wt;

[0093] e. Adding an initiator and keeping warm at 50-80° C. for 3-8 hours to form a polymer at the oil-water interface to obtain the low-crossli...

Abstract

The invention discloses a preparation method and a preparation device of a microcapsule printed fabric. The preparation method comprises the following steps of (1) preparing a low-crosslinking shell microcapsule; (2) mixing the low-crosslinking shell microcapsule with a compound emulsifier to obtain printing paste; and (3) printing the printing paste to obtain the microcapsule printing fabric with improved hand feeling. According to the preparation method and the preparation device of the microcapsule printed fabric provided by the invention, on the premise that the functionality of the microcapsule is guaranteed, the hand feeling and the air permeability are improved, so that the wearing experience is enhanced; and meanwhile, a series of overall technical solutions of the low-crosslinking shell material microcapsule, the printing paste and the microcapsule printed fabric capable of improving the hand feeling are given, and the microcapsule printed fabric can be used for various natural or synthetic material fabrics by simply replacing materials, so that the universality is good, and popularization is easy.

Description

technical field [0001] The invention relates to the field of printed textiles, in particular to a method and device for preparing microcapsule printed fabrics. Background technique [0002] Microcapsule is a new type of functional material developed in recent years. Microcapsules are tiny containers on the micron or submicron scale. Structurally, microcapsules are composed of shell material and core material. The shell material is usually various polymer materials. The core material is a variety of materials with special properties, including phase change materials, plant flavors, vitamins, flame retardants, chemical inhibitors and so on. In short, a microcapsule is a tiny container loaded with functional substances. [0003] This new material can not only impart new functionality, but also avoid the loss of functional materials during processing, and at the same time enhance the compatibility between different materials, which can be said to serve multiple purposes. Th...
