Embodiment 1

[0017] A method for improving the flatness of a single-sided TPU composite fabric mainly includes adding the following steps between the priming step and the TPU film-coating step in the production process of the TPU composite fabric:

[0018] Step (1), roll-forming process: roll the coated fabric obtained after priming on the shaft, the number of meters in the roll is 1000 meters, and the diameter of the roll is determined according to the thickness of the fabric. The rolls of fabric are then placed on the unwinding frame and pushed into the curing chamber.

[0019] Step (2), ripening treatment: place a humidifier in the ripening chamber, the power can be determined according to the size of the ripening chamber. Turn on the humidifier to pre-humidify the coated fabric. Indoor temperature: room temperature. Indoor humidity: 30% RH. Curing time: 24h.

[0020] Step (3), pre-treatment of TPU coating: After the machine is set up, before starting the coating, add water to the h...

Embodiment 2

[0022] A method for improving the flatness of a single-sided TPU composite fabric mainly includes adding the following steps between the priming step and the TPU film-coating step in the production process of the TPU composite fabric:

[0023] Step (1), roll-forming process: roll the coated fabric obtained after priming on the shaft, the number of rolls is 5000 meters, and the diameter of the roll is determined according to the thickness of the fabric. The rolls of fabric are then placed on the unwinding frame and pushed into the curing chamber.

[0024] Step (2), ripening treatment: place a humidifier in the ripening chamber, the power can be determined according to the size of the ripening chamber. Turn on the humidifier to pre-humidify the coated fabric. Indoor temperature: room temperature. Indoor humidity: 90% RH. Curing time: 24h.

[0025] Step (3), pre-treatment of TPU coating: After the machine is set up, before starting the coating, add water to the humidifier to ...

Embodiment 3

[0027] A method for improving the flatness of a single-sided TPU composite fabric mainly includes adding the following steps between the priming step and the TPU film-coating step in the production process of the TPU composite fabric:

[0028] Step (1), roll-forming process: roll the coated fabric obtained after priming on a shaft, with a roll diameter of 50 cm. The rolls of fabric are then placed on the unwinding frame and pushed into the curing chamber.

[0029] Step (2), ripening treatment: place a humidifier in the ripening chamber, the power can be determined according to the size of the ripening chamber. Turn on the humidifier to pre-humidify the coated fabric. Indoor temperature: room temperature. Indoor humidity: 50% RH. Curing time: 24h.

[0030] Step (3), pre-treatment of TPU coating: After the machine is set up, before starting the coating, add water to the humidifier to ensure the normal operation of the humidifier during the production process, adjust the humi...

Abstract

The invention provides a method for improving the single-face TPU compound fabric flatness for the technical problems that a sample wafer rolls up after being be cut and sampled, and is easy to blend and the next working procedure is not easy to carry out. The technical scheme adopted in the invention is as follows: the method for improving the single-face TPU compound fabric flatness is characterized in that following steps are added between a priming step and a TPU laminating step in the production process of a TPU compound fabric: step (1) coiling treatment; step (2) curing treatment; and step (3) TPU laminating pretreatment. By adopting the technical scheme, after the treatments such as curing and pre-humidification are adopted, a force generated when a coating fabric extends outside and droops after absorbing moisture and shrinkage of a TPU film can form a balanced force, so that the TPU compound fabric can not generate coiling or irregular phenomena, the subsequent working procedures are easy to perform, and meanwhile, the fitting fastness and other performances of the TPU products can not be influenced.

Description

technical field [0001] The invention belongs to the technical field of textile coating fabric processing, in particular to a method for improving the flatness of a single-sided TPU composite fabric. Background technique [0002] TPU (Thermoplastic polyurethanes) is a thermoplastic polyurethane elastomer, which has the characteristics of high strength, good toughness, wear resistance, cold resistance, aging resistance, and weather resistance. With many excellent functions such as warmth retention, anti-ultraviolet radiation and energy release, it is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. TPU composite fabric is to use TPU film to compound on various fabrics to form a composite material, and combine the characteristics of the two to obtain a new type of fabric. [0003] In the conventional production process of TPU composite fabric, the fabric is first scraped and primed by a scraper to form a coated fabric; then the coa...
