Embodiment 1

[0038] (1) Process the high-strength and low-stretch polyester filament through the network and make it into a chemical fiber fabric with plain weave / twill weave for subsequent use;

[0039] (2) Use 1.5d×38mm polyester staple fiber and polyester-based bonded staple fiber PES to make a bonded non-woven fabric through mixing, laying, carding, needle punching, and hot pressing. The hot pressing condition is temperature 155℃, time 3 seconds;

[0040] (3) Apply the first slurry to the spare chemical fiber fabric: speed 400 m / h, temperature 150°C, sizing amount 105 g / m 2 , park for 24 hours, apply the second slurry: speed 400 m / h, temperature 150°C, sizing amount 105 g / m 2 , parked for 12 hours after standby;

[0041] (4) The first sizing on non-woven fabric: speed 300 m / h, temperature 100 ℃, sizing amount 120 g / m 2 , park for 24 hours, apply the second slurry: speed 400 m / h, temperature 100°C, sizing amount 105 g / m 2 , parked for 12 hours after standby;

Abstract

The invention discloses a chemical fiber long silk fabric/ ternary adhesive/short nonwoven fiber stacked composite anti-transpierce shoe midsole and a method for manufacturing same. The stacked composite anti-transpierce shoe midsole comprises various materials such as multi-layer high-strength low-stretching chemical fiber long silk fabrics, ternary adhesive, short nonwoven fabrics and the like, wherein the chemical fiber long silk fabric is the high-strength low-stretching type chemical fiber long silk compact textile, the ternary adhesive is the mixed solution consisting of high temperature-resistance graft chloroprene adhesive, latex and vulcanized mucilage, and the short nonwoven fiber is formed by sequentially mixing, carding, paving, puncturing and hot-pressing the PET staple fiber and polyester-based PES fiber. The preparation method adopts a way of single-layer fractioning and multi-layer compounding on the textile and uses the processes of hot-pressing as well as the slab vulcanization. The method can prepare the anti-transpierce shoe midsole of safety shoes, can prepare the anti-transpierce shoe midsole of the molding safety shoes particularly, and has the advantages of good anti-transpierce effect, flexibility and easy bend, firm combination with the sole, no lamination and the like.

Description

technical field [0001] The invention relates to a laminated composite anti-piercing shoe midsole and a manufacturing method thereof, which are used for making the puncture-resistant midsole of safety shoes, in particular for making the puncture-resistant midsole of molded safety shoes. Background technique [0002] The soles for daily wear are composed of rubber and plastic soles, midsoles, and insoles. On this basis, anti-puncture materials can be added to make safety shoes with anti-puncture functions (or training combat boots for troops). Usually, the puncture-resistant material is punched out of plates such as stainless steel and manganese steel to make the puncture-resistant midsole, so as to prevent the sole from being pierced by sharp objects and hurting the sole of the foot. [0003] Chinese patent 200720047148.6 provides a new type of puncture-resistant sole, which consists of a stainless steel front and a hard plastic rear, wherein the shape of the front matches th...
