Problems solved by technology

Due to the film-like airtightness of the film, the seamless underwear produced by this process cannot achieve the desired effect in terms of air permeability, comfort, extensibility, and firmness.
Difficult to meet modern women's requirements for underwear comfort, beauty and durability
At the same time, the difference in bonding strength also limits the use of seamless heat pressing technology on other garments

preparation example Construction

[0033] The present invention also provides a preparation method of water-based dispensing, by weighing 30-40 parts of thermoplastic resin, 1-2 parts of dispersant, 1-2 parts of emulsifier, 1-2 parts of plasticizer, 1-2 parts of Thickener, 1-2 parts of bactericide, 1-2 parts of defoamer and 50-65 parts of water are mixed evenly to obtain water-based dispensing.

[0034] The present invention also provides a method of using water-based dispensing: firstly, through the screen printing process, the glue is sprayed on the joint of the fabric, and arranged intermittently in small dots, and then hot-pressed and cooled to make the fabric stick to the fabric. together and fixed. The water-based dispensing in this embodiment is in the form of a cream, which can be directly attached to the fabric; the dispensing adhesive performance is excellent, and the tensile ductility is good, which can meet people's requirements for comfortable, beautiful and durable underwear.

Abstract

The invention relates to water-based dotting glue. The water-based dotting glue is prepared from, by weight, 10-30 parts of a phosphoric acid-phosphate binding agent, 20-30 parts of silicon carbide, 20-30 parts of kyanite, 20-30 parts of zirconium dioxide, 20-30 parts of mullite, 10-20 parts of titanium dioxide, 5-10 parts of a reinforcing agent, 5-10 parts of an anti-cracking slow-release agent,9-11 parts of ceramic powder resin, 2-5 parts of an accelerator and 2-5 parts of a grinding aid. The dotting glue has the advantages that the ceramic powder resin has the functions of increasing the hardening speed of inorganic mineral nodules, improving the compactness and the like, so that the anti-burst performance of high-strength concrete at the high temperature is improved; the phosphoric acid-phosphate binding agent mainly achieves the effect of collecting microaggregates, correspondingly the using amount of cement can be decreased, the bonding force of the cement and aggregate is enhanced, and the fluidity of the concrete is improved, so that the compactness of the concrete is improved. The high-strength concrete made of the cement is subjected to a high-temperature effect under open fire at 1,200 DEG C for 1 hour, the appearance is kept complete, no crack is generated, and the compressive strength is not lower than 90 MPa.

Description

technical field [0001] The invention relates to the field of chemical adhesive materials, in particular to a water-based dispensing method and a preparation method thereof. Background technique [0002] With the improvement of human living standards, in addition to meeting the basic physiological needs of clothing, more emphasis is placed on the comfort of clothing, the individuation of styles, characteristics and functionality. Traditional sewing and garment-making technology will cause disadvantages such as poor wrinkle resistance, large shrinkage rate, and poor elasticity of the garment, which will result in poor comfort of close-fitting clothing, such as women's underwear, underwear, tight sportswear, swimsuits, etc. In order to meet people's pursuit of comfortable underwear, people continue to innovate and improve in fabrics, technology, design and other aspects. The seamless underwear produced on the basis of seamless weaving technology finds the best product interpre...
