Embodiment approach

[0062] The inspected products are taken as a batch, and three pairs are selected from them for inspection.

[0063] The first is the performance control of the main and auxiliary raw materials:

[0064] (1) Standard natural rubber: the breaking strength of raw rubber is not less than 19.6MPa, and the elongation at break is not less than 680%;

[0065] (2) High wear-resistant carbon black: a) Pure carbon black test indicators: PH value 7-9.5, oil absorption value 0.90-1.15, DPG adsorption rate 4-8%, 100-mesh sieve residue less than 0.02%; b) physical Performance index (Physical properties of the film prepared according to the following ratio: 300g smoked rubber, 9g stearic acid, 3g anti-aging agent CD, 15g zinc oxide, 1.8g accelerator M, 9g pine tar, 9g sulfur, high wear resistance Carbon black 150g, total 496.8g.): tear strength ≥ 24.5MPa, elongation at break ≥ 470%, 300% elongation strength ≥ 11.76MPa, Acron wear volume ≤ 0.22cm 3 / 1.61km;

[0066] (4) Zinc oxide: content ...

Abstract

The invention discloses a quality controlling method for a pair of cloth cover moulded shoes. The method consists of the control to raw materials, appearance and physical and mechanical properties, wherein, the raw materials comprise standard natural ruuber, carbon soot with high wear resistance, zinc oxide, stearic acid, accelerant DM, accelerant M, sulfur, space-variant terylene filament canvas and terylene filament flat hair plush; the appearance comprises the appearance of an upper semifinished product and the appearance of a finished shoe; the physical and mechanical properties comprise the bond strength of the upper with a foxing, the wear-resisting performance of external bottom, the strength and elongation performance of the external bottom, the hardness of a glue component, aging performance of glue stuff and the air permeability and the moisture permeability of the upper. The invention establishes a novel quality controlling method for a pair of cloth cover moulded shoes, improves the quality control standard of moulded shoes and ensures the performances of the moulded shoes better, such as the comfortableness for wearing, the wearing resistance, etc.

Description

technical field [0001] The invention relates to the technical field of cloth molded shoes, in particular to a quality control method for cloth molded shoes. Background technique [0002] Cloth molded shoes are of molded vulcanized structure, including cloth molded single shoes and cloth molded cotton shoes, which are favored by consumers because they are comfortable to wear, light and practical, and have a casual and elegant appearance. [0003] The preparation method of molded shoe is: [0004] 1. Production of semi-finished products: the textile materials that meet the technical requirements are made into shoe uppers, which are used for molding after passing the inspection; at the same time, the chemical raw materials and rubber that pass the inspection are made into molded shoe rubber parts on the rubber mixer, and then Use rubber compound to make semi-finished film and adhesive glue. [0005] 2. Forming and manufacturing of molded shoes: First, the qualified upper and ...
