Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all Example.

[0023] The pretreatment method of the all-cotton heavy-duty self-adhesive bandage in the present embodiment comprises the steps:

[0024] A preparation of the base material: the base material is made of pure cotton material, and the weight of the pure cotton material is selected from 160 to 200gsm; Thick, so that the self-adhesive bandage can meet the high-strength requirements;

[0025] Production of B base material: the base material is set as a woven fabric, so that the fabric texture is formed on the base material to improve the aesthetics, and the spandex yarn is configured, and the spandex yarn is covered with a process to form a...

Abstract

The invention discloses a pretreatment method for a full-cotton heavy type self-adhering bandage. The pretreatment method includes the steps that a, during preparation of a substrate, the substrate isselected to be made of pure cotton materials, and a selected gram weight ranges from 160 gsm to 200 gsm for the pure cotton materials; b, during making of the substrate, the substrate is set to be woven fabric, spandex filaments are arranged, the spandex filaments are coated to form stretch yarns, and the multiple stretch yarns are arranged on the surface of the substrate; c, during preparation of a padding reagent, the padding reagent is composed of, by weight, 2-4 parts of mixtures of methyl acrylate and ethyl acrylate, 1-2 parts of water and 0.05-0.2 part of cross-linking agent, wherein the proportion of the methyl acrylate to the ethyl acrylate is 1:1 during mixing; d, during finishing, the padding reagent in the step C is adopted for finishing the substrate in the mode of padding.

Description

technical field [0001] The invention relates to a pretreatment method of an all-cotton heavy-duty self-adhesive bandage. Background technique [0002] The non-woven self-adhesive bandages currently used mainly use polypropylene as the base material, and the base fabric is made through the spinning and hot pressing process, and then the spandex yarn is formed on the base fabric by a professional crochet machine to complete the base. The production process of the material, the weight of the base material is about 40gsm, the breaking strength is greater than 25N / inch, the adhesiveness of the self-adhesive bandage to the plate is greater than 0.8N / inch, and the elasticity ratio is greater than 2.0; it can be cut into multiple specifications and has multiple colors You can choose; this non-woven self-adhesive bandage is cheap and widely used, and it is currently the most widely used product. [0003] In addition to the economical non-woven self-adhesive bandages, the self-adhesi...
