Embodiment Construction
[0020] The preparation method of a fiber mesh skeleton hot-melt adhesive gangbao of the present invention is prepared through the following steps:
[0021] Step 1. Preparation of the middle layer. The spunlace nonwoven fabric produced by polypropylene raw materials is used. The spunlace nonwoven fabric uses multiple strands of fine water jets generated by high pressure to spray the fiber web, and the fibers are arranged in a certain direction. The spunlace nonwoven fabric Cloth is a known product;
[0022] Step 2, soaking for the first time, put the spunlace non-woven fabric of step 1 in the first glue tank and soak it with mixed latex for 10-13 minutes, preferably 10 minutes, to obtain the first soaked body; this mixed latex It is prepared from water-soluble polyester, EVA granules and titanium dioxide. The water-soluble polyester and EVA granules are first mixed and stirred for 28-32 minutes. The weight ratio of water-soluble polyester to EVA granules is 2:1. After stirring ...

Abstract
The invention provides a preparation method of a hot melt adhesive counter of a fiber web skeleton. The preparation method comprises the following steps: 1, a spunlace non-woven fabric produced by a polypropylene raw material is selected; 2, the spunlace non-woven fabric is put in a first glue groove and soaked by adopting a mixed latex, and soaked for 10-13 minutes to obtain a first soaking body;3, manual glue scraping treatment is performed, and then thickness pressing treatment is performed; 4, second soaking is performed; 5, second shaping is performed; 6, pressing and finishing treatmentis performed; and 7, curing treatment is performed, and a processing sheet carries out heat curing in a thermal curing box, an then immediately transferred into a cooling curing box for cooling and curing to obtain a shaped finished product, wherein the shaped finished product is a non-woven mesh fabric inside, and the outer surface of the shaped finished product is a fiber web skeleton hot meltcounter of a hot melt colloid. The hot melt counter with a middle layer made by the spunlace non-woven fabric can be prepared, and has the advantages of being high in structural strength, not prone todeformation, soft, light and thin, good in resilience, excellent in weather resistance and wear resistance, and capable of being decomposed and environment-friendly, and uppers of sneakers are liableto shaping.
Description
technical field [0001] The invention relates to a hot-melt adhesive gangbao, in particular to a preparation method of a fiber mesh skeleton hot-melt adhesive gangbao. Background technique [0002] Hot-melt adhesive Gangbao is used for the front lining and back lining parts of sports shoes, and is an important material in the sports shoe manufacturing industry. After the hot-melt glue Gangbao is shaped in the sports shoe cavity, the shoe shape is straight and round, not easy to deform, and has excellent resilience, excellent weather resistance and wear resistance, which greatly improves the comfort and appearance of the sports shoes. At the same time, it has the plasticity of thermoplastic materials; the viscosity does not change after repeated use; the product is not sticky after heating and softening. [0003] According to the principle of protective space in sports mechanics, not only the front of the shoe must have sufficient strength, but the heel should also be able to...
