CN1952225A - Maize protein colored textile fiber and method for producing same - Google Patents

Abstract

The invention provides a colored fiber of corn protein and manufacture method. There is activated dye in corn protein. The manufacture method is that activated dye is added in the process for confecting spinning solution and plant protein colored fiber with the density of 0.7-3.0dtex is slubbed by wet spinning technology after ripening and polymerizing in reaction vessel. Because of activated dye added in confecting process, strike and fixation rates are improved. In detection method the cooler fiber has good fastness with five degree and enough light. There are no pollution and public disaster in the activated dye. The fiber is provided with good moisture conduction, light gravity, dry heat resistance and so on. It is knitted and tatted to various ultrathin or thickening apparel fabrics with high grade.

Description

Maize protein colored textile fiber and production method thereof

Technical field

The invention belongs to textile material, relating in particular to by soybean protein fibre and REACTIVE DYES is that the look of component spins fiber, also relates to the manufacture method of this colored spinning fiber (spinning hereinafter to be referred as look) simultaneously.

Background technology

Zein fiber just had the zein fiber production of " Vicara " by name as far back as 1948, it is a Zein fibers, and to nineteen fifty-seven, corn Vicara fiber is formally manufactured by Virginia, The United States-Ka Liluolaina chemical company.Soon afterwards, the U.S. well-known Cargill cereal company develops successfully " corn acid fiber by polylactic ", and " output was once reaching 6000 tons to drop into batch process.Manufacture method by plant protein synthetic fiber and this fiber is disclosed among national patent CN99116636.1 and the CN02109966.9 in addition.More than the fiber of its production need to dye bleaching look thereafter because the cellulose fibre strand is a polypeptide polymer, not anti-caustic soda, protein fibre all can be subjected to infringement in various degree in highly basic still is weak base, even cause decomposing.The fastness of acid dyeing is very poor, albumen is in separation, purifying and spinning process process, suffered obvious impairment, the amino negligible amounts during amino acid is formed, so the ability of combination dye reduces greatly, again because the protein of this fiber mainly is distributed in fibrous outer, negligible amounts, and swelling comes off easily, so even a large amount of ACID DYES are gone up in absorption, dyestuff also comes off under damp and hot and Frotteurism with protein easily, and color is not bright-coloured yet.In addition, we prove that quite a few dyestuff also is adsorbed in the cellulose composition of fiber internal layer, but fastness is very poor, low in glossiness.Easier fading under the ultraviolet ray irradiation.

Summary of the invention

Purpose of the present invention provides color fibre exactly, and the COLOR FASTNESS that overcomes former technology is poor, the shortcoming of low in glossiness.Saved the back look dyeing technique in the former fabrication processes, to spinning material, all very favourable to environmental protection.

The technical scheme that the present invention proposes to address the above problem is; Adopted the first production technology that dyes and afterwards weave.In the process of preparation spinning solution, add the vital staining material, fully maturation, polymerization in reactor, and use wet spinning technology, be spun into the phytoprotein colored fibre of fine density 0.8-2.4dtex.Owing in system liquid process, add REACTIVE DYES, improved dye uptake and fixation rate.This colored fibre after testing, the good fat light foot of COLOR FASTNESS.COLOR FASTNESS can reach the 4-5 level.This REACTIVE DYES is pollution-free, nuisanceless, have and good lead moist and wet putting.Light specific gravity strength and elongation height, acid-fast alkali-proof performance are good.Soft, smooth, drapability is better than silk.Anti-boiling water shrinks and dry heat resistance.Can be knitting, tatting becomes the high-grade fabric of various ultra-thin or thickenings.

Description of drawings

Patent specification of the present invention comprises a width of cloth accompanying drawing

Fig. 1 is the process chart of patent of the present invention

The specific embodiment

(1) corn protein preparation, polyethylene soaks, the mill base preparation;

(2) the poly-ethanol of corn protein and immersion back, mill base are joined reactor, heat 55 ℃-105 ℃, reacted 100-120 minute;

(3) add the coloured system liquid of activating agent;

(4) spinning;

(5) crosslinked;

(6) full gear; (being up to state standards)

(7) curl;

(8) cut off;

(9) Vacuum shaping;

(10) packing.

Use activating agent, percentage preparation by weight:

Sodium phosphate---0.1-0.3%

Sodium perborate---0.2-0.5%

Sodium tetraborate---0.4-0.6%

Second is milled amine---0.2-0.4%

Bio-ethanol---0.4-0.6%

Dibenzoyl peroxide---0.6-0.8%

REACTIVE DYES, percentage preparation by weight:

Active blue or green ED-2G 0.3-0.5%

Reactive yellow ED-2G 0.3-0.5%

Reactive red ED-3B 0.3-0.5% various active dyestuff, REACTIVE DYES has different proportionings, makes the source liquid of different colours.

In our spun staple fibre detects, use above three kinds of REACTIVE DYES, can dye the mill base of tens kinds and tens kinds different colours.In the final experiment of weaving face fabric, water-fast washing with UV resistant shone.COLOR FASTNESS is fine, and bright in colour.This colored fibre, following market is very wide.
