CN103046381A - Process method for improving tear resistance of coating fabric - Google Patents

Abstract

The invention discloses a process method for improving the tear resistance of a coating fabric. According to the method, a softening agent RCF-RTR which has good chemical stability and is capable of endowing the extra soft and fluffy handfeel on fibers and a waterproof agent Tg-536 are adopted for co-bathing and padding. The process method is capable of meeting the waterproof function and improving the tear strength.

Description

A kind of process that improves the coated fabric tear resistance

Technical field

The present invention relates to a kind of process that improves the coated fabric tear resistance, belong to field of textiles.

Background technology

The coating tent cloth that uses under the general environment is easily torn under the effect of strong wind or certain force in the place of seam, has caused certain economic loss.

Summary of the invention

The shortcoming that exists in order to overcome prior art the invention provides a kind of process that improves the coated fabric tear resistance, and it is characterized in that: concrete steps are as follows:

(1) material

Prescription: RCF-RTR (silicone softening agent) and the water of the Tg-536 of 35g/l (weak cation type waterproofing agent), 0.5g/l;

In the material still, put into the cold water of half volume, then start agitator, RCF-RTR is poured in the material still while stirring, be finished down rear agitator until RCF-RTR and continue to stir 10min, stir again 5min after adding second half water, stir 5-6min after adding at last Tg-536, obtain the oyster white homogeneous latex emulsion;

(2) base cloth pads in above-mentioned emulsion through setting machine, and oven dry;

(3) coating;

(4) the typing tentering obtains finished product.

Advantage of the present invention: processing step is simple, and cost is low, can satisfy water-proof function, can improve tearing strength again.

The specific embodiment

Below be to further specify technical scheme of the present invention by embodiment.

Embodiment 1

(1) material

Prescription: RCF-RTR (silicone softening agent) and the water of the Tg-536 of 35g/l (weak cation type waterproofing agent), 0.5g/l;

In the material still, put into the cold water of half volume, then start agitator, RCF-RTR is poured in the material still while stirring, be finished down rear agitator until RCF-RTR and continue to stir 10min, stir again 5mi n after adding second half water, stir 5-6min after adding at last Tg-536, obtain the oyster white homogeneous latex emulsion;

(2) base cloth pads in above-mentioned emulsion through setting machine, and oven dry;

(3) coating;

(4) the typing tentering obtains finished product.

The result that the coated fabric that the present invention is obtained is tested: can be under the hydraulic pressure of 3000mm water column waterproof 90mi n; Tearing toughness radially 〉=6.5N, broadwise 〉=5.5N.
