A kind of print paste and stamp silk twill production technology
Technical field
The present invention relates to a kind of print paste and stamp silk twill production technology, this print paste and stamp silk twill production technology may be used for preparing heavy pound stamp silk twill.
Background technology
Silk fabric is thin only bright and clean, and have gloss soft, quality is frivolous, soft and high resilience, and hygroscopicity is strong, magnificent noble quality, to characteristics such as body-cares, can be made into clothes, ornament, indoor article, handicraft etc.Heavy-weight silk is the twice silk amount with common silk fabric, forms through special process is spinning, and outward appearance is graceful, gloss is soft, comfortable and easy to wear.Heavy-weight silk except possessing the feature of common silk fabrics, also have shrink-proof, well-pressed, easily arrange, not easily scratch, fabric weight is greater than 40g/m
2, fabric is fine and closely woven abundant, and feel is soft lubricious, and sense of hanging down is powerful, elegant quality.Be not only the desirable fabric making autumn and winter jacket, wind coat, ladies' suit, and summer Men's Casual Wear, fitted pants and one-piece dress for lady Fashion, become dress to wear to the noble magnificent sensation of people.
Silk twill is a kind of real silk fabric being organized as the similar drillipg of twill structure, and cloth cover has obvious oblique lines, good hand touch, gloss, elasticity better.The silk twill positive and negative printed color difference of below the 14MM of prior art is little, silk twill positive and negative stamp is clear.But heavy-weight silk twill silk stamp is more difficult.Such as 18.5MM silk twill, the raw material of employing is warp: 3/20/22D filature silk, warp density 74/CM; Parallel 5/20/22D filature silk, weft density 41/CM; The raw material that 20MM silk twill adopts is warp 3/20/22D filature silk, warp density 74/CM, parallel 5/20/22D filature silk, weft density 44/CM.The graticule density of these two kinds of heavy-weight silk twill silks spends height, fabric tightness is high, space between fiber is little, in stamp process, concentrator not easily passs through interfibrous space and penetrates into reverse side from the front of silk twill, causes that silk twill positive and negative printed color differs greatly, stamp is unintelligible.
Summary of the invention
In order to reduce heavy-weight silk twill silk positive and negative printed color difference, make heavy-weight silk twill silk positive and negative stamp clear, the invention provides a kind of print paste.
In order to solve above technical problem, technical scheme of the present invention is: a kind of print paste, comprises following component by mass fraction:
Printing gum 8% ~ 12%;
Urea 8% ~ 10%;
Dyestuff 0.01% ~ 5%; The scope of described dye molecule amount is 500 ~ 800;
All the other compositions are water;
Described printing gum is prepared from by the component of following mass fraction:
Modification melon glue seed extract 18 ~ 20%;
Preservative agent 0.8 ~ 1.2%,
All the other compositions are water.
The preparation method of described printing gum is by described modification melon glue seed extract, preservative agent and water, after mass fraction mixing, mixer stirs 45 ~ 50 minutes, then the H2SO4 of 5% is added, at 70 DEG C, be hydrolyzed 2 ~ 2.5 hours after mixing, then adding NaOH, to be neutralized to PH be 6.5 ~ 7.
As preferably, described print paste viscosity is 4000 ~ 5000CPS.
As preferably, described dyestuff is weak acid dye or reactive dye for wool.
Described reactive dye for wool is preferably LANASOL type reactive dye for wool, and described weak acid dye is preferably ERIONYL type dye.Wherein, described LANASOL type dye be selected from LANASOL Huang-4G, the black CE-PV of blue 8G-01, LANASOL dark blue B-01, LANASOL sauce of LANASOL bright red 3G, LANASOL red 6G, LANASOL red B, LANASOL blue 3G, LANASOL red CE, LANASOL palm fibre CE, LANASOL dark blue CE-R, LANASOL any one.Described ERIONYL type dye be selected from ERIONYL yellow A-R, ERIONYL red B-10B, ERIONY blue A-R, ERIONYL bright blue A-G and ERIONYL orange B-GRLS any one.
Compared with prior art, concentrator provided by the invention, printing gum adopts modification melon glue seed extract, and the scope of dye molecule amount is 500 ~ 800; Adopt this concentrator counterweight pound stamp silk twill stamp, flower pattern is meticulous, and concentrator infiltration is good, and heavy-weight silk twill silk positive and negative printed color difference reduces greatly, and positive and negative color and luster flower pattern is clear.
In order to solve above technical problem, the present invention also provides a kind of stamp silk twill production technology, comprises the following steps:
Step (1): weave silk twill, and refining treatment is carried out to described silk twill;
Step (2): stamp, adopts above-mentioned print paste to described silk twill stamp;
Step (3): decatize, adopts the saturated vapor of 102 DEG C ~ 108 DEG C by the silk twill after stamp, decatize 40 minutes ~ 50 minutes;
Step (4): washing, washes the silk twill after decatize 15 minutes ~ 20 minutes on open width continuous washing machine at 40 DEG C ~ 60 DEG C;
Step (5): dry, arranges the silk twill after washing through three-in-one blanket;
Step (6): fixation, by silk twill, the water be placed in containing 0.02% ~ 0.1% color-fixing agent pads, evenness calender, pressure 8KG, a leaching one is rolled.
Step (7): tentering is dried and HEAT SETTING, silk twill was processed for 20 seconds on tentering heat setting machine at 120 DEG C, obtains stamp silk twill.
As preferably, the 19.5MM silk twill that to be grammes per square metre be of silk twill described in step (1), the raw material warp of employing is 4/20/22D filature silk, warp density 55/CM; Parallel is 6/20/22D filature silk, weft density 37/CM, and grammes per square metre is 19.5MM.
Reasonably combined by graticule raw material choose and graticule density degree, adjustment silk twill institutional framework, add the fiber number of longitude and latitude raw material, reduce graticule density degree, increase the space between fiber, thus improve the penetrating power of print paste on silk twill, contribute to print paste and penetrate into reverse side from silk twill front, reduce silk twill positive and negative printed color difference, make silk twill positive and negative stamp clear, improve printing quality.
What graticule adopted is the high-grade filature silk of more than 5A level, and this type of filature silk silk gum fibroin content is uniform and stable, is conducive to thoroughly removing silk gum in scouring processes; do not damage fibroin simultaneously; the fineness of protection fabric, is conducive to dye material and penetrates into silk thread inside, and uniformly penetrating is to fabric backing.
As preferably, in step (1), use full-automatic decorating machine to described silk twill stamp.
As preferably, it is 2Kg ~ 4Kg that described full-automatic decorating machine scrapes pressure, in this pressure limit, contributes to improving print paste osmotic effect, avoid scraping simultaneously pressure excessive and produce scrape paste.
As preferably, described full-automatic decorating machine printing table temperature is 35 DEG C ~ 40 DEG C, in this temperature range, is conducive to the infiltration of print paste, avoids the too low fineness affecting flower pattern of Yin Wendu simultaneously.
As preferably, the mode that scrapes of described full-automatic decorating machine scrapes for jumping version; Screen Printing screen frame order number is 150 order ~ 180 orders.
Use full-automatic decorating machine to described silk twill stamp in step (1).
Full-automatic decorating machine controls to scrape pressure and printing table temperature automatically, keeps scraping pressure printing table temperature stabilization in stamp process, reduces silk twill positive and negative printed color difference, makes silk twill positive and negative stamp clear, improve printing quality.
Compared with prior art, stamp silk twill production technology provided by the invention, by the improvement to weaving process and concentrator, the heavy pound stamp silk twill flower pattern of preparation is meticulous, concentrator infiltration is good, heavy-weight silk twill silk positive and negative printed color difference reduces greatly, and positive and negative color and luster flower pattern is clear.The stamp silk twill adopting this production technology to prepare may be used for preparing heavy pound stamp silk twill scarf.
Detailed description of the invention
