Embodiment Construction

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in further detail below in conjunction with specific embodiments.

[0027] The invention discloses a production process of medical fabric, which comprises the following steps:

[0028] 1. Gray cloth weaving, select low-denier nylon yarn material, and weave on the loom. In this embodiment, 20-70 denier fully stretched cotton fiber 66 yarn material (single filament meeting 4G / D) is selected. The weave is designed as a plaid cloth with a warp and weft density of 145*132 and a width of 63 inches, which is woven on a loom. The weave design considers plaid, double-grid or multi-line plaid with 2 or 3 grid sides, or dobby-style prismatic fabric. Using this kind of weave design can improve the tear resistance and overall strength of the fabric .

[0029] 2. Desizing, desizing the woven gray fabric on the desizing machine, ...

Abstract

The invention discloses a production technology of a medical fabric. The technology comprises the following steps of grey fabric weaving, desizing, drying, splashing and sizing, calendering treatment, and coating of a double-sided coating, wherein the calendered surface of the fabric is coated with a PU resin coating with water pressure resistance; the PU resin coating is divided into a PU polyether two-component base material and a PU one-component fabric for separate coating; after the calendered surface is coated, the fabric is dried through high-temperature oven until being rolled up, and the other side of the fabric is coated with an organic silicone coating, and high-temperature drying is carried out to obtain the medical fabric. The tissue style characteristics of the woven fabric are integrated, and coating finishing is carried out on the front and reverse sides of the fabric, so that the fabric has the characteristics of being waterproof, easy to decontaminate and high in tenacity, and the production technology is suitable for the medical fabric.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production process for medical fabrics. Background technique [0002] Medical materials are high-performance medical textiles. Since the working environment of medical staff is complex and they are easily exposed to radiation, static electricity, and highly infectious bacteria and viruses, they require high safety and softness. It has the effects of waterproof and anti-seepage, no dandruff, and easy decontamination. [0003] Invention patent 2012100057265 discloses a waterproof and permeable coating fabric and its preparation method, including water repellent treatment, calendering treatment, primer coating, surface glue coating and other steps. It is waterproof and breathable, but has poor decontamination. Suitable for sports fabrics, not suitable for medical fabrics. [0004] Invention patent 2014108528383 discloses a functional medical fabric and its preparation method. I...
