Embodiment 1

[0052] A weft printing process, comprising the following processes:

[0053] Bleached yarn base (exhaust dyeing, liquor ratio: 20:1, temperature 30°C, time 30min) → washing and drying → weaving (using base yarn as weft yarn) → printing → color development → alkali washing → sodium bisulfite Liquid washing→hot water washing→cold water washing→drying;

[0054] Among them, the formula of the primer is: 12.5g of naphthol AS, 16.5mL of 30% NaOH, 7.5mL of penetrant JFC, and 1000mL by adding water

[0055] Among them, the printing paste formula is: chrome red B 100g, 30% hydrochloric acid 200mL, sodium nitrite 60g, starch-long glue paste 2750g, sodium acetate and acetic acid to buffer the pH to 4.5, add water to synthesize 5000g

[0056] Among them, the printing equipment is a flat screen printing machine.

Embodiment 2

[0058] The present invention adopts following technical scheme:

[0059] A weft printing process, comprising the following processes:

[0060] Bleached yarn base (exhaust dyeing, bath ratio: 18:1, temperature 25°C, time 25min) → washing and drying → weaving (use base yarn as weft yarn) → printing → color development → alkali washing → sodium bisulfite Liquid washing→hot water washing→cold water washing→drying;

[0061] Among them, the primer formula is: naphthol AS 10g, 30% NaOH 15mL, penetrant JFC 5mL, add water to form 1000mL;

[0062] Among them, the printing paste formula is: chrome red B 80g, 30% hydrochloric acid 180mL, sodium nitrite 50g, starch-long glue paste 2600g, sodium acetate and acetic acid to buffer the pH to 4, add water to make 5000g

[0063] Among them, the printing equipment is a flat screen printing machine.

Embodiment 3

[0065] The present invention adopts following technical scheme:

[0066] A weft printing process, comprising the following processes:

[0067] Bleached yarn base (exhaust dyeing, liquor ratio: 22:1, temperature 35°C, time 35min) → washing and drying → weaving (use base yarn as weft yarn) → printing → color development → alkali washing → sodium bisulfite Liquid washing→hot water washing→cold water washing→drying;

[0068] Among them, the primer formula is: Naphthalene AS 15g, 30% NaOH 18mL, penetrant JFC 10mL, add water to form 1000mL;

[0069] Among them, the printing color paste formula is: 120g of chrome red B, 220mL of 30% hydrochloric acid, 70g of sodium nitrite, 2900g of starch-long glue paste, appropriate amount of sodium acetate and acetic acid to buffer the pH to 5, and add water to make 5000g

[0070] Among them, the printing equipment is a flat screen printing machine.

Abstract

The invention relates to a weft and pattern printing process. The warp yarn printed with patterns are weaved, the obtained fabric has a special style with obscure and colored effects and strong three-dimension effect, and the printed pattern has the glimmering effect, is elegant, soft and rich in characteristics. The weft and pattern printing process is a convenient and feasible special pattern-printing method. The weft and pattern printing process not only can be used for pure-cotton products, but also can be applied to fabrics such as acrylic fibers and blends.

Description

technical field [0001] The invention relates to the textile field, in particular to a weft printing process. Background technique [0002] In the weaving process of cotton, linen or chemical fiber blended fabrics, the fabric is divided into two groups perpendicular to each other by yarns and interwoven on the loom. A group along the longitudinal direction of the fabric is called warp yarn; a group along the transverse direction of the fabric is called weft yarn. The process of interweaving warp and weft yarns on a loom is called weaving engineering (knitted fabrics are woven using circular knitting machines or flat knitting machines). After the warp and weft are ready, the loom is used to weave the cloth. There are many types of looms, which can be divided into shuttle looms, shuttleless looms, and two-layer looms. There are plain weave, twill weave, satin weave and jacquard weave for warp and weft yarn interweaving. The identification of warp and weft yarns in woven fabr...
