Problems solved by technology

However, this method has the following fatal disadvantages: (1) Since no flame retardant is used in the double-sided coating, only the non-washable flame-retardant finishing of the base fabric, the flame retardancy of this tarpaulin cannot meet some standards Regulations (its smoldering time ≥ 7s)
(2) Because there is no flame retardant in the coating, in order to reduce the influence of the coating on the flame retardancy of the tarpaulin, the amount of glue applied should not be too large, so the coating film is too thin and the strength is low, and the coating is easy to rub off when used in summer
(3) Due to the double-sided coating, the vapor permeability of the tarpaulin is poor
The applicant's application involves breathable, waterproof and oil-proof fabrics, but does not involve the treatment of infrared protection and comprehensive oil resistance, and the process is also different

Embodiment Construction

[0016] Vapor-permeable, flame-retardant, oil-proof, water-proof, acid-proof and near-infrared polyester tarpaulin is a multi-functional protective fabric with specified fiber materials. Its core protective function is flame retardancy and oil-proof, waterproof and acid-proof performance, and the flame-retardant processing is carried out in two steps (base fabric first and then coating). Phosphorus-halogen flame retardants are used for the durable flame-retardant finishing of the base fabric and the flame-retardant coating, and fluorine-containing compounds are used for the oil-proof, waterproof and acid-proof treatment, so that the phosphorus-halogen flame retardant and the fluorine-containing acid-proof agent have the same synergistic effect . The solution of vapor permeability (wetness) depends on the modification of PU coating resin and one-sided coating. The near-infrared protection is to add suitable dyes to the PU coating slurry, and make a reasonable formulation of the ...

Abstract

The present invention relates to a preparation process of breathable fire-retardant oil-proofing water-proofing acid-proofing and anti-near-infrared polyester sailcloth. Said preparation process includes the following several steps: firstly, making permanent flame retardant treatment of polyester sailcloth, said permanent flame retardant treatment includes padding and baking, baking temperature is 170 deg.C-200deg.C, baking time is 1-10 min, coating flame retardant PU coating adhesive, making water-proofing and acid-proofing treatment, drying and baking for 1-10 min, at 170-230 deg.C, then making permanent flame retardant of base cloth, dyeing, coating flame retardant PU coating adhesive, making water-proofing, oil-proofing and acid-proofing treatment.

Description

technical field [0001] The invention relates to the preparation of a multifunctional fabric, in particular to the preparation of a vapor-permeable, flame-retardant, oil-, water-, acid-, and near-infrared-proof polyester tarpaulin. Background technique [0002] Polyester fiber is the most productive variety among chemical fibers, accounting for about 70% of the total output. In recent years, polyester fiber has been widely used in industrial textiles, especially tarpaulins. Polyester tarpaulins are mainly used for vehicles, boats, aircraft covers, open-air material covers, tourism and lifesaving tents, and cloth for horses and horses. vinyl latex tarpaulin). But they are all airtight. In recent years, there have also been reports on the study of vapor-permeable flame-retardant and waterproof pure polyester tarpaulin, but its smoldering time is relatively long (7-8 seconds), which does not meet the requirements of relevant domestic and foreign stand...
