Description
Technical field
The present invention relates to textile processing field, be specifically related to preparation technology and the application thereof of the fire-retardant all-cotton fabric of a kind of water and oil repellant.
Background technology
Because existing greasy dirt, operation place, naval vessel is infected with and disaster hidden-trouble; Work Clothes is as human body and extraneous shielding; should there is the oil of refusing, refuse water and fire resistance, thereby effectively protect human body to escape injury, keep soft feel, excellent durability and snugness of fit simultaneously.
Rear arrangement is that fabric obtains the major way of refusing oil, water repellency, and essence is in fabric face absorption layer of substance, makes the high energy surface of fabric become low-energy surface, obtains the fabric of refusing oil, refusing water effect with this; And fabric face can be less, refuse oil, refuse water effect better.
Du pont company has carried out the trial of fluoropolymer fabric water and oil repellent finish at first the 1950's.Afterwards, 3M company has researched and developed the fabric finishing agent taking perfluorocarboxylic acid chromium complex as main component, but this perfluorocarboxylic acid chromium complex fabric finishing agent is replaced by the better fluorine-containing propene vinegar of performance polymer soon, becomes the main flow of refusing now water, refusing oil and soil resistant finish.Refuse that water, oil-repellent finiss technique should " roll and cure " according to the corresponding employing of actual requirement, the process route of top finish and the two combination.
Make fabric obtain one of method of fire resistance for flame-retardant finishing method, fabric is carried out to surface treatment, to reach fire-retardant object.This processing mode comprises spraying, pads and three kinds of coatings.Wherein, the processing mode padding is mainly used in processing dress ornament series products.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of novel, possess simultaneously refuse water, refuse oil, the cotton fabric of resistant, the performance such as fire-retardant, and the preparation method and application of this fabric are disclosed, for textile processing industry provides new fabric panel.
First the present invention discloses the preparation technology of the fire-retardant all-cotton fabric of a kind of water and oil repellant, comprises the steps:
1) weaving: adopt cotton fiber to spin, weave, obtain grey cloth;
2) pre-treatment and dyeing;
3) flame-proof treatment: grey cloth is immersed in fire retarding treating liquid, pads successively, dry, bake, wash and dry;
4) water and oil repellent finish: grey cloth is immersed in water and oil repellent finish liquid, pads successively, dry, bake, soap, wash and dry;
5) postfinishing process;
Wherein, described in step 3), fire retarding treating liquid is the aqueous solution that comprises following component and concentration:
380～420g/L Pyrovarex CP (antiflaming finishing agent)
18～22g/L phosphoric acid (catalyst)
12～17g/L uric acid
10～20g/L softener
Described in step 4), water and oil repellent finish liquid is the aqueous solution that comprises following component and concentration:
45～55g/L Oleophobol CP-C (water-refusing oil-refusing finishing agent)
18～22g/L knittex FEL(crosslinking agent)
12～16g/L knittex CATALYST MO LIQ(crosslinking agent)
4～6g/L wetting agent.
Preferably, described in step 1), cotton fiber is long-staple cotton fiber.
Preferably, the resultant yarn mode of spinning described in step 1) is RING SPINNING, and the fineness of yarn is 12～20S.Preferably the fineness of yarn is 12S, 16S, 20S.
Preferably, in weaving process, fabric structure adopts 1/3 twill-weave described in step 1).
Why the present invention adopts 1/3 twill-weave to be because 1/3 twill-weave is best in the latitudinal strength of twill the inside, and other tissue affects weaving efficiency and fabric quality, increases cost.
Preferably, described in step 3), flame-proof treatment is specially: grey cloth is immersed in fire retarding treating liquid, and two soak two rolls, pick-up rate 85～95%; 100～110 DEG C of bake out temperatures, dry 2～5min; 160～180 DEG C of baking temperatures, bake 40～70s.
More excellent, flame-proof treatment is specially described in step 3): grey cloth is immersed in fire retarding treating liquid, and two soak two rolls, pick-up rate 90%; 100 DEG C of bake out temperatures, dry 3min; 170 DEG C of baking temperatures, bake 60s.Be that flame-proof finishing process flow process is: pad (two soak two rolls, pick-up rate 90%) → dry (100 DEG C, 3min) → bake (170 DEG C, 60s) → wash → dry (100 DEG C, 3min).
Preferably, the formula of described fire retarding treating liquid is as follows:
400g/L Pyrovarex CP (antiflaming finishing agent)
20g/L phosphoric acid (catalyst)
