A kind of canopy fabric with anti-drenching rain leakage and anti-pocket water leakage performance and its manufacturing method

Abstract

The invention provides an overcanopying fabric with rain seepage prevention and water containing seepage prevention performance and a manufacturing method of the overcanopying fabric. The method comprises the following steps that a fabric to be treated is provided; a jet dyeing machine is used for applying water repllents to the fabric to be treated, so the fabric subjected to water repllent treatment is obtained, wherein the jet dyeing machine uses work fluid for pushing the rope-shaped annular fabric to be treated to do rotary operation, the operation speed of the fabric can be between 300 m / min and 800 m / min, and the jet dyeing machine can apply the water repllents for 15 to 30 minutes at 40 to 80 DEG C and at the bath ratio between 1 / 3 and 1 / 12; the fabric subjected to the water repllent treatment is subjected to drying, amplitude shaping and forming, so the formed fabric is obtained; the formed fabric is subjected to calendaring processing, so the overcanopying fabric is obtained, wherein the pressure of a padder can be 1 to 5kg / cm<2>, the temperature of the padder can be 30 to 90 DEG C, and the speed of the padder can be 16 to 32 m / min. The invention also provides the overcanopying fabric with rain seepage prevention and water containing seepage prevention performance manufactured according to the manufacturing method.

Description

technical field [0001] The invention relates to a canopy fabric with anti-rain leakage and anti-pocket water leakage performances and a manufacturing method thereof. In particular, the present invention relates to a canopy fabric that can obtain functions of preventing rain leakage and pocket water leakage without coating or laminating processing. Background technique [0002] In the transportation industry, it is necessary to use canopy fabrics to cover the transported materials, automobiles / aircrafts / helicopters and other large-scale transportation machinery to avoid damage to goods and equipment due to rain and water leakage; large-scale operation machinery working in the field also needs to have canopy fabrics Covering construction machinery, especially precision equipment, placed in the field can prevent rainwater seepage due to rain or partial water leakage, and prevent damage to equipment. The canopy fabric needs to have light weight, high strength, no weight increas...

Problems solved by technology

[0003] However, the current canopy fabrics are mostly cotton fabrics or polyester-cotton fabrics, which are prone to water leakage. The method of coating finishing or film coating to improve the anti-leakage performance will increase the weight and affect the operation, increase the labor intensity of the user, and It will affect the moisture permeability of the canopy fabric, affect the moisture dissipation of the covered object, and increase the cost; the conventional canopy fabric will also affect the operation due to water absorption and weight gain

For flame-retardant tarpaulins, some fabrics have insufficient tensile and tear strength and low service life due to the use of low-strength flame-retardant fibers; some have strength due to the preparation of cotton fabrics and polyester fabrics. low, hard to the touch, and even odor; when applying the coating, a flame-retardant coating must be used to take into account both the anti-water leakage performance and the flame-retardant performance, and the weight gain of the flame-retardant coating will reach 50g / m 2 The above makes it very difficult to use the tarpaulin to cover the aircraft, vehicles and large outdoor equipment, and it is even more difficult to complete the work when encountering strong wind and heavy rain
