Description
Technical field
The present invention relates to a kind of textile water proof processing technology.
Background technology
Water with can be penetrated into fabric back after common weaving face fabric contacts and influence appearance of fabrics and comfortableness.Therefore, the waterproof fabrics demand that can be widely used in special climate, the particular surroundings such as daily life and rainy day, hot summer days, high temperature, field is more and more vigorous.When possessing water resistance, the breathable moisture permeability of fabric also needs to take into account.That is to say that the rainwater that molecular diameter is bigger does not immerse fabric under certain pressure, and the sweat of body can spread, and prevents that sweat from accumulating between body surface and fabric with the form of the less steam of molecular diameter by fabric, thereby keep the comfort of body.
Waterproof fabrics roughly is divided three classes.One class is to come the high-density fabric of Waterproof Breathable by the space of fabric itself, such as Coolmax class fabric, sweat can be excreted at the microchannel of its fibrous inside, can prevent that rainwater from infiltrating simultaneously again.This class fabric is grasped production technology by international major company, belongs to high-end product, and market penetration rate is low.Another kind of is to realize waterproof by microporous membrane, with the kinds of processes technology HAIR COLOR COMPOSITION is coated on fabric face, solidifies back formation film, thereby seals or reduce the function of the space realization Waterproof Breathable of fabric itself.This type of fabric poisture-penetrability is relatively poor, can not satisfy basic Waterproof Breathable needs.The 3rd class is the non-porous film waterproof moisture permeating fabric, thereby form the purpose that nonporous film reaches waterproof with HAIR COLOR COMPOSITION coating, oven dry back at fabric face, the hydrophilic radical that the macromolecule in the while waterproofing agent contains is given fabric ventilation and perspiration function performance by penetration mechanism.The thickness of controlling diaphragm is quite important in the treatment process of this class fabric.
Summary of the invention
The object of the present invention is to provide a kind of textile water proof processing technology, be applicable to the processing of aforementioned the 3rd class non-porous film waterproof moisture permeating fabric.Reach the viscosity that coating and equipment processing need by the proportioning of regulating the waterproof combination agent, control every indexs such as temperature in the process, the speed of a motor vehicle, equipment simultaneously, guarantee that overlay film thickness is more than 10uM.This technology can solve the unmanageable problem of waterproof coating thickness in the existing textile water proof treatment technology, makes fabric obtain durable water resistance, and does not influence the breathable moisture permeability of processing fabric.
For reaching above purpose, the method applied in the present invention may further comprise the steps:
A) with rotary screen printing machines coating waterproof combination agent, this combination agent comprises waterproofing agent, crosslinking agent, thickener and water;
B) typing bakes.
The compound method of described waterproof combination agent is:
A) in waterproofing agent, progressively add earlier water and form dispersion;
B) with dispersion and the abundant mixing of crosslinking agent;
C) in dispersion, add thickener and regulate composition viscosity.
Wherein, as if being 100 parts of unit of weights with the waterproofing agent consumption, dosage of crosslinking agent is 15-21.5 part unit of weight
,The thickener consumption is 14-20 part unit of weight, and the consumption of water is 870-1300 part unit of weight, and combination agent viscosity is between the 3700-4000 centipoise.
Rotary screen printing machines is selected 105 order cylinder net embryos and No. 10 bar magnets.The speed of a motor vehicle be the 15-20 sign indicating number/minute.Machine seal comprises that drying process, purpose are to dry moist fabric after the coating waterproof combination agent, and drying temperature is 150-170 ℃.
Typing bakes in the step soaks fabric in advance in the typing auxiliary agent.The typing baking temperature is 150-170 ℃.The speed of a motor vehicle be the 25-30 sign indicating number/minute.
In a preferred embodiment of the invention, described typing auxiliary agent comprises antiseptic, and consumption is 0.5%.
In a preferred embodiment of the invention, described typing auxiliary agent comprises inhales apparent perspire agent, and consumption is 3%.
Compared with prior art the present invention has the following advantages:
1. be widely used in synthetic fiber, natural fabric and blended fabric thereof, as terylene, nylon, cotton, silk, hair etc.;
2. water resistance is lasting;
3. the breathable moisture permeability that keeps fabric;
4. can carry out the processing of single face waterproof processing or double-faced waterproofing according to demand.
