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
A preparation method of fiber mesh skeleton hot-melt adhesive gangbao of the present invention is prepared through the following steps: 1. Spunlace non-woven fabric produced by selecting polypropylene raw materials; 2. Putting it in the first glue tank and using mixed latex Soak, soak for 10-13 minutes to get the first soaked body, step 3, firstly carry out manual scraping treatment, and then carry out thickening treatment, step 4, soak for the second time, step 5, set the shape for the second time, step 6, ironing Trimming treatment, step 7, curing treatment, heat curing in the heat curing box first, then immediately transfer to the cooling and curing box to cool and solidify, and obtain a shaped product. The shaped product is a non-woven mesh inside and a hot-melt surface The colloidal fiber mesh skeleton is hot-melted Gangbao. The invention can prepare hot-melt gangbao whose middle layer is spunlace non-woven fabric, which has the advantages of high structural strength, not easy to deform, soft and thin, good resilience, excellent weather resistance and wear resistance, and can be decomposed and environmentally friendly, and is easy to wear for sports shoes Knot forming.
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...
