Embodiment 1

[0035] Embodiment 1: A double-sided tearable fabric for medical adhesive tape, including a fabric body formed by interlacing warp yarns and weft yarns, both warp yarns and weft yarns are made of polyester modified fibers. Among them, ordinary polyester fiber is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions. Fiber polymer - polyethylene terephthalate (PET), fiber made by spinning and post-processing. It has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crisp, easy to wash and dry, and not easy to fluff.

[0036]In order to properly weaken the binding force between fiber molecules and reduce the fiber strength, in addition, the warp and weft yarns are all 100D polyester modified fibers. It is obtained by modifying the body and the fourth monomer. In addition, the third monomer ado...

Embodiment 2

[0039] Embodiment 2: A double-sided tearable fabric for medical adhesive tape, the difference from Embodiment 1 is that the third monomer is sodium terephthalic acid sulfonate, such as 2-sulfonic acid terephthalic acid Monosodium salt, which has the molecular formula C 8 h 5 NaO 7 S, its molecular formula contains 2 carboxyl groups; when added in the polymerization reaction, the hydrophilic group on the fiber can be increased at this time to increase the moisture regain of the fiber, thereby weakening the bonding force between the fiber molecules and making the crystallization more loose , the fiber strength is further reduced. And the fourth monomer is polyethylene glycol, its chemical formula is HO(CH 2 CH 2 O) n H, it not only has good water solubility, but also has good compatibility with many organic components; it also has excellent lubricity, moisture retention, dispersibility, adhesive, antistatic agent and softener.

Embodiment 3

[0040] Embodiment 3: a double-sided tearable fabric for medical adhesive tape, the difference from embodiment 1 is: the third monomer is sodium salt of isophthalic acid sulfonate, such as 5-thioisophthalic acid Monosodium, which has the molecular formula C 8 h 5 NaO 7 S, its molecular formula contains 2 carboxyl groups; when added in the polymerization reaction, the hydrophilic group on the fiber can be increased at this time to increase the moisture regain of the fiber, thereby weakening the bonding force between the fiber molecules and making the crystallization more loose , the fiber strength is further reduced. The fourth monomer is 1,4-dimethylolcyclohexane, 1,4-dimethylolcyclohexane, also known as bis(hydroxymethyl)cyclohexane, which is composed of dimethyl terephthalate The methanol solution of the ester (or ethylene glycol terephthalate) is produced by hydrogenation reduction under pressure and can be used as a lubricant.

Abstract

The invention discLoses doubLe-face tearabLe fabric for medicaL adhesive tape and a processing method of the fabric and beLongs to the technicaL fieLd of textiLes. The doubLe-face tearabLe fabric forthe medicaL adhesive tape is characterized by comprising a fabric body which is formed by interweaving warp and weft, and poLyester modified fibers are adopted for the warp and the weft and obtained in the mode that third monomers containing hydrophiLic groups and / or fourth monomers containing hydrophiLic groups are added to poLyester fibers during a poLymerization reaction for modification treatment. The processing method comprises the steps of cyLinder preparation and roLLing, coLd pad-batch desizing, water washing reroLLing, in-cyLinder embrittLement, water washing out-cyLinder, finishing and formation and packaging storage in a warehouse. The fabric is durabLe and does not fLuff, the operation is simpLe, an operator more convenientLy uses the fabric, and more Labor is saved; accordingto the processing method, the fiber strength of the fabric body can be effectiveLy Lowered, and accordingLy the good tearabLe performance and effect of the fabric body are improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and more specifically relates to a double-sided tearable fabric used for medical adhesive tape and a processing method thereof. Background technique [0002] The base material of existing medical packing tape product is pure wood pulp natural material, non-toxic and non-irritating, has good gas permeability. Medical packing tape has good softness, easy unwinding and convenient operation; it is suitable for cross-shaped packing wrapped in sterile cotton cloth used by medical institutions and enterprises. It is suitable for central disinfection supply room, operating room, stomatology department, etc. [0003] At present, most of the existing fabrics used to make medical tapes are made of non-tearable cotton cloth. At this time, the cotton cloth will not only fluff during use, but also the operator needs to use scissors or other materials when using it. Tool for cropping, relatively inconvenient...
