Description

A kind of production method of soft coating dye printing flannelette

Technical field

The present invention relates to method for textile production, the production method of the flannelette of particularly printing and dyeing.

Background technology

Dyeing will actively be applied clearer production technology transformation dyeing and finishing processing status, to efficient, high-quality, short flow process, energy-conservation, consumption reduction, low-cost, safety, reliable, of low pollution development, to meeting the processing of dyeing and finishing economy.The textile printing and dyeing drying technologies such as the wrinkle proofing technology of clearer production technology, natural fabric, and the employing of environment-friendly type dye addictive and new type functional auxiliary agent contributes to improve the class of textile product and increases added value.

Flannelette has gloss feature soft, soft, comfortable and easy to wear.Traditional coating is printed and dyed, and the flannelette COLOR FASTNESS of producing is poor, Boardy Feeling, and active dye printing operation is many, easily staining.And traditional handicraft use active dye printing operation is longer, washing difficulty is large, and cost is high.Compare dye printing and dyeing, the advantages such as coating dye printing has that technique is simple, technological process is short, product is checked colors conveniently, it is little to pollute and cost is lower, but use that first coating dye printing will overcome that traditional coating dyeing cloth exists that feel is stiff, colour brightness is poor, friction and the shortcoming such as washing fastness is poor, because coating is water-fast tiny solid particle, fiber is not had to affinity, need adhesive to be anchored at fiber surface, be difficult to keep the peculiar style of high-quality flannelette, therefore, the performance of flannelette needs to improve at present.

Summary of the invention

The object of the invention is to overcome above-mentioned not enough problem, a kind of production method of soft coating dye printing flannelette is provided, overcome that traditional coating dyeing colour fastness is poor, the shortcoming of Boardy Feeling, the disadvantage of having avoided many, the easy staining of active dye printing operation, the flannelette making has gloss feature soft, soft, comfortable and easy to wear.

The technical scheme that the present invention adopted is for achieving the above object: the production method of soft coating dye printing flannelette, and concrete technology step is:

1) destarch: adopt alkali-oxygen bath technology, carry out two in padding liquid and soak two and roll, pick-up 105%-115%, decatize 30min at latter 100 ℃;

2) napping: carry out 105～115 ℃ of oven dry in following padding liquid, the positive three anti-nappings of napping machine four;

3) preliminary treatment: adopt washing or mercerising, the fritter face not mercerising of printing and dyeing, bristle washing before printing and dyeing, the printing and dyeing of bulk face adopt the mode of light mercerising: sodium hydroxide concentration 120-160g/L;

4) printing and dyeing: first prepare following mill base mixed liquor, adopt cylinder dyeing machine to print and dye, bake out temperature lower than 120 ℃, rotating speed 45～55m/min, 150 ℃ of baking temperatures, bake time 4～6min, coating dye printing mill base aqueous formulation is as follows, is mixed with mill base viscosity 60～70dPaS:

Printing and dyeing coating 1～5%, paint dyeing and printing adhesive agent 8～20%, coating dye printing thickener 4～5%;

5) dry: soft width is selected softener acid solution, 105～115 ℃ of prebake temperature, 160～180 ℃ of width bake out temperatures, rotating speed 45m/min, adopts preshrinking machine to carry out preshrunk after soft width.

The advantages such as the present invention compares dye printing and dyeing, and coating dye printing has that technique is simple, technological process is short, product is checked colors conveniently, it is little to pollute and cost is lower.The use of flexibility pigment printing paste and auxiliary aid has overcome that traditional coating dyeing cloth exists that feel is stiff, colour brightness is poor, friction and the shortcoming such as washing fastness is poor, and the product making keeps the peculiar style of flannelette.What adhesive was effective and lasting anchors at fiber surface by coating, and fastness is good, and good hand touch and content of formaldehyde are low.The highly energy-consuming operation such as technical process reduced washing, evaporate, has saved energy expenditure greatly, has reduced sewage discharge.

The specific embodiment

Below in conjunction with specific embodiment, the present invention is described in further detail, but the invention is not restricted to specific embodiment.

The production method of soft coating dye printing flannelette, concrete technology step is:

1) destarch: adopt alkali-oxygen bath technology, carry out two in padding liquid and soak two and roll, pick-up 105%-115%, decatize 30min at latter 100 ℃;

2) napping: carry out 105～115 ℃ of oven dry in following padding liquid, the positive three anti-nappings of napping machine four;

3) preliminary treatment: adopt washing or mercerising, the fritter face not mercerising of printing and dyeing, bristle washing before printing and dyeing, the printing and dyeing of bulk face adopt the mode of light mercerising: sodium hydroxide concentration 120-160g/L;

4) printing and dyeing: first prepare following mill base mixed liquor, adopt cylinder dyeing machine to print and dye, bake out temperature lower than 120 ℃, rotating speed 45～55m/min, 150 ℃ of baking temperatures, bake time 4～6min, coating dye printing mill base aqueous formulation is as follows, is mixed with mill base viscosity 60～70dPaS:

Printing and dyeing coating 1～5%, paint dyeing and printing adhesive agent 8～20%, coating dye printing thickener 4～5%;

5) dry: soft width is selected softener acid solution, 105～115 ℃ of prebake temperature, 160～180 ℃ of width bake out temperatures, rotating speed 45m/min, adopts preshrinking machine to carry out preshrunk after soft width.

The quality of coating quality directly affects vividness and the COLOR FASTNESS of color and luster.The coating that particle is thin, interparticle light scattering effect is strong, and absorptivity is large, and tinting strength, tinting power is high, and can form good covered effect after adhesive film forming, improves rub resistance and the washing fastness of printing product.
