Description

Seamless sculpture elastic cord production facility

Technical Field

The invention relates to the field of production equipment of elastic fabrics, in particular to production equipment of seamless sculpture elastic bands.

Background

In the market, the parts of the underpants, the leg openings, the neckline, the cuffs, the hem, the waistline and the like are all finished by connecting or internally wrapping the rubber band and the elastic woven belt with the large body piece if the parts are required to be stretched when the trousers are worn.

Because of the limitations of the traditional sewing process, only a few decorative patterns can be added to the appearance improvement. When the elastic band manufactured by the traditional sewing process is worn, extreme fatigue, rebound resilience loss, wrinkle returning and folding are easily caused during use. And the sewing thread for splicing also limits the elasticity of the woven belt, so that the woven belt is uncomfortable to wear, and the cloth of the clothes of the sewing thread is separated from the woven belt to form a separated state.

Aiming at the defects, the production equipment of the elastic woven belt is improved.

In conclusion, the invention has the following beneficial effects: 1. the automatic equipment adopts a rotary table rotary structure, is time-saving and labor-saving, can automatically perform circular operation, and greatly improves the production benefit;

2. steam heating is adopted to avoid sol bonding by a traditional electric heating method, the electric heating is destructive to vulcanization oxidation of a polyurethane adhesive high molecular structure, so that the bonding fastness risk is large, the current is unstable, the product color difference is large, and the steam heating well avoids the problems;

3. because the meshbelt expandes when pressing and scalding, utilize the electric heat mould to preheat, recycle steam mould and play decisive pressure to scald to finished product fastness bonding, can make hot melt adhesive membrane dissolve meshbelt and base cloth and paste an organic whole, this process utilizes steam heating, avoids vulcanizing the oxidation destruction to sticky fat. Because the elastic polyurethane is a high-molecular linear polymerization structure, the density is above 40000-50000PCS, the molecular structure moves slowly, and after heating, glue molecules slowly permeate into fibers, so that the viscosity and the durability of a glue film are ensured, and the bonding fastness of a product is improved. After the polyurethane is shaped by steam, the firmness and the softness of adhesive bonding and no color difference between bonding positions and base cloth can be ensured by utilizing the steam shaping.

4. Because the woven belt is unfolded during pressing and ironing, the process needs to be extended and hot-pressed and then retreated, and degumming is easily caused because no cooling process is adopted in the retreating and contracting process, a cooling system needs to be added. The elastic polyurethane is a high-molecular linear polymerization structure, the density is above 40000-50000PCS, the molecular structure moves slowly, and after heating, glue molecules slowly permeate into the fibers, so that cooling is carried out by utilizing an air draft cooling system, and air cooling is a relatively natural slow cooling process, so that the glue molecules can be fully fused with the fibers, and the adhesive effect of the glue can be fully exerted. If suddenly cooled, the fusing action is stopped, which has the effect of setting the chemical fiber of the base cloth and has the adverse effect of reducing the adhesiveness on the high molecular polyurethane, thus affecting the adhesion fastness.
