Embodiment 1

[0017] 1) Warp-knitted mesh cloth: use a weft-inserted warp-knitting machine to warp-knit the warp and weft in full-width weft-insert, and weave it into a mesh fabric. The warp is 30D 24F polyester FDY, and the weft is 100D 48F polyester DTY;

[0018] 2) Heat setting and finishing: under tension, use a slightly higher temperature than the subsequent process to prevent the fabric from shrinking and deforming. Dry heat setting is used to enter the warp knitted mesh into the domestic model M-751, or M-751A needle clip chain heat setting machine, overfeed 2 ~ 4%, carry out clip tentering, and then enter the warp knitted mesh cloth of the tenter into the heating zone with a temperature of 180 ~ 210 ℃, heat for 2 ~ 15 Seconds, then cool the cloth to a temperature less than 50°C and drop the cloth.

[0019] The mesh fabric after the above heat treatment is added into the treatment bath and finishing bath used in the dyeing and finishing process of the fabric, such as flexibilizer, pe...

Embodiment 2

[0023] 1) warp-knitted grid cloth: warp and weft full-width weft-inserted warp-knitting with weft-inserted warp-knitting machine is used to weave into mesh fabric, the warp uses 50D 48F acetate fiber, and the weft uses 60D 70F polyurethane fiber;

[0024] 2) Heat setting and finishing: This step makes the fabric shape relatively stable and fixes the overlapping parts of the warp and weft of the mesh cloth. The thermoplastic fiber fabric will generate internal stress during the weaving process, and it will be affected by the humidity, heat and external force in the dyeing and finishing process. Under the condition that wrinkles and deformation are prone to occur, dry heat setting is adopted, and the warp knitted mesh cloth is fed into the dual-purpose needle plate cloth clip type, and the overfeed is 2 to 4%, and the needle clip tenter is carried out, and then the warp of the tenter The woven grid cloth enters the heating zone with a temperature of 180-210°C, heats for 2-15 seco...

Embodiment 3

[0029] 1) Warp-knitted mesh cloth: use a weft-inserted warp-knitting machine to warp-knit the full-width weft-inserted warp and weft threads, and weave them into a mesh fabric. The warp threads use monofilaments made of 45D 40F polyvinyl chloride, and the weft threads use 100D 80F glass fiber;

[0030] 2) Heat setting and finishing: This step makes the fabric shape relatively stable and fixes the overlapping parts of the warp and weft of the mesh cloth. The thermoplastic fiber fabric will generate internal stress during the weaving process, and it will be affected by the humidity, heat and external force in the dyeing and finishing process. In this situation, wrinkles and deformations are prone to occur. Put the warp-knitted mesh cloth into the dual-purpose needle plate cloth clip type, overfeed 2 to 4%, carry out the needle clip tentering, and then put the warp-knitted mesh cloth of the tenter Enter the heating zone with a temperature of 180-210°C, heat for 2-15 seconds, then...

Abstract

The invention relates to a manufacture technique of easy tear tape, comprising the following steps: 1) tricot grid cloth: using a tricot weft insertion machine to carry out full tricot weft insertion on the warp and weft to be knitted into mesh fabric; 2) thermal forming and finishing: carrying out thermal treatment on the mesh fabric and sizing treatment on a sizing machine by using a sizing agent; 3) compounding: using high temperature melt resin on the front and back faces, and carrying out direct film sprinkling treatment to obtain a three-layered structural film shape substrate; and 4) adhesive coating: directly coating pressure-sensitive adhesive on the substrate followed by drying, or pre-coating the pressure-sensitive adhesive on a mold release substrate and drying followed by being transferred to be compounded onto the three-layered substrate to obtain the adhesive tape with viscosity. The invention has the beneficial effects that the tape produced by the technique of the invention can be torn off transversely with slight force in use, can be directly torn off without special tools, and the transverse torn part is neat, so that the adhesive material looks neat and beautiful in appearance, the use is safe and convenient, the working efficiency is improved and task cost is reduced.

Description

technical field [0001] The invention relates to an adhesive tape manufacturing process, in particular to an easy-to-tear adhesive tape manufacturing process. Background technique [0002] There are many kinds of tapes and are widely used, but most tapes need to be cut with special tools when they are used, and often the cut edges are not neat, which not only wastes time, reduces work efficiency, but also looks very unattractive to the pasted materials. Therefore it is necessary to provide a manufacturing process for producing easy-tear tapes. Utility model content [0003] The object of the present invention is to provide a kind of easy-tear adhesive tape manufacturing process, to overcome the disadvantages that the existing product adhesive tape needs to be cut with a special tool, and the cutting edge is not neat. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A kind of easy-tear adhesive tape manufacturi...
