Abstract

The invention provides a production process of a fluoride-free waterproof breathable knitted fabric. The production process comprises the following steps of: (1) raw material preparation: weaving a gray cloth with single side being of a fleece tissue structure; (2) preprocessing: preprocessing the gray cloth, wherein the processing liquid contains 1.2-1.7g/L of low-temperature scouring and bleaching agents, 1.8-2.2g/L of hydrogen peroxide activating agent, 1.8-2.2g/L of anti-creasing agent, 6-7g/L of hydrogen peroxide and 3.5-4.5g/L of caustic soda liquid; (3) dyeing: dyeing the gray cloth, wherein the dyeing liquid contains 7-9% of anhydrous sodium sulphate and 0.5-0.7% of substitutive soda by weight percent; (4) drying: drying the gray cloth; and (5) setting and finishing: setting the gray cloth in a setting machine, wherein a waterproof finishing agent in the finishing liquid is organic silicone emulsion and a catalyst is an emulsifier. The produced fabric has better breathability and wear and use durability, is aired at room temperature after being washed, without high temperature drying and ironing maintenance and overcomes the defect that the common waterproof and oilproof fabrics have poor breathability and stability and need high temperature drying and ironing maintenance after being washed.

Description

A kind of production technology of fluoride-free waterproof breathable knitted fabric
Technical field
The present invention relates to a kind of production technology of fluoride-free waterproof breathable knitted fabric.
Background technology
Along with the development of modern society, the improving constantly of people's living standard, various comfort properties, appearance property and the property of textiles more and more come into one's own.Some new textile through special finishing can provide the function of various excellences to people, thereby meet the requirement of specific use, and it is exactly wherein a kind of that knit fabric waterproof and breathable arranges.Traditional waterproof knit fabric Collator Mode has three kinds: (1), be to carry out top finish at fabric face, and as Corvic coating, polyurethanes resinous coat, the shortcoming of top finish is there is no gas permeability; (2), be laminated, as tetrafluoroethylene laminated fabric, this waterproof and breathable membrane type is by micropore principle, the clothes of making easily make blockage of the micro orifice in wearing process, cause breathing freely or micropore becomes large, waterproof airing function variation after washing times 5 times; (3), be to adopt fluorine carbon water repellent to arrange, can realize moderate oil repellent energy, little on the impact of fabric air-permeability performance, but this class garment material is difficult for arranging, and needs hyperthermia drying or flatiron could keep its waterproof and breathable performance after dress.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of produce there is efficient WATER REPELLENCY, the production technology of fine air permeability and washable fluoride-free waterproof breathable knitted fabric.
Object of the present invention realizes by following technical solution:
A production technology for fluoride-free waterproof breathable knitted fabric, comprises the steps:
(1), raw material preparation, braiding one side is defended the grey cloth of clothing institutional framework;
(2), pre-treatment process, grey cloth is carried out to pre-treatment, treatment fluid is containing the low temperature of 1.2-1.7g/L scouring and bleaching Activation of Hydrogen Peroxide Solution agent, the anti-creasing agent of 1.8-2.2g/L, the liquid caustic soda of the hydrogen peroxide of 6-7g/L, 3.5-4.5g/L of agent, 1.8-2.2g/L;
(3), dyeing, grey cloth is dyeed, dyeing liquor is containing the percentage by weight glauber salt that is 7-9%, the substitute alkali of 0.5-0.7%;
(4), stoving process, grey cloth is dried;
(5), sizing finishing technique, in setting machine, grey cloth is carried out to heat treatment, the water-proof aagent in dressing liquid is that organic silicon emulsion, catalyst are emulsifying agent.
Described dressing liquid contains the water-proof aagent of 18g/L, the catalyst of 4g/L.
The bath raio of described pre-treatment process is 1:4, and temperature is 78-83 ℃, and the time is 45-55min.
The bath raio of described dyeing is 1:4, and temperature is 60-65 ℃, and the time is 40-50min.
The knitted material of described grey cloth selects 100% cotton textiles, veil JC32S(match network to spin), filling C16SX2, braiding parameter: blank grammes per square metre is 280g/m 2, blank door width is 110 * 2cm, and JC32S line length is that flat pin 38cm/ ties up a mao 45cm/100G, and C16S/2 line length is 18.5cm/100G.
The present invention has following beneficial effect:
The knit fabric tool that adopts the present invention to produce has the following advantages: efficient WATER REPELLENCY and fine air permeability, and function lasting stability, washable number of times is more than 20 times; , containing organic fluorocarbon compounds, do not comprise PFOS, PFOA and APEO; After washing, can at room temperature dry, not need hyperthermia drying and flatiron maintenance just can keep refusing water effect; Fabric is soft level and smooth, is better than coated fabric and fluorine carbon waterproof fabrics, comfortable and easy to wear, can be used for all types of clothes.
The processing of traditional cotton fabric boiling and bleaching process is carried out at more than 98 ℃ high temperature, steam economy is large, under high temperature, high alkalinity and hydrogen peroxide exist, cloth cover feel is not good, and loss is large, fabric strength loss is large, and wrinkle easily appear in cloth cover, affect fabric quality, for overcoming the above problems, the present invention has developed Low temperature pretreatment, carries out pre-treatment under cryogenic conditions.
In dyeing, adopt polishing and dyeing one to bathe enzyme glossing and dyeing are carried out in same bath, adopt biological substitute alkali fixation to solve the problems such as the consumption that traditional fixation alkali brings is large, operation inconvenience, Yi Sehua, the time is long, production efficiency is low.
Aspect the formulation of sizing finishing technique, by a large amount of experimental studies the usage ratio of water-proof aagent and catalyst, the ratio summing up at consumption 18:4 is issued to superior water-proof breathable properties and the washing resistance that is applicable to knit fabric.The environmental protection of fabric green ecological is not containing organic fluorocarbon compounds (being PFOS/PFOA) and APEO, soft level and smooth, improved the not environmental protection of general waterproof fabrics containing organic fluorocarbon compounds (being PFOS/PFOA) and APEO, the shortcomings such as Boardy Feeling.
