Abstract

The present invention relates to a kind of based on the crosslinked fabric anti-crease finishing method of spray process point-like, the sprinkling equipment that utilization can accurately be controlled sprays crease-shedding finishing agent drop on fabric equably with certain size and spacing, after heat treatment and/or electron beam irradiation, form even, intensive, discontinuous crosslinking points in fabric, form point-like cross-linked structure. Crosslinking points fixed member chain, prevent that strand from producing large slippage, for fabric provides wrinkle resistance, between molecule segment between crosslinking points and fiber, possesses certain relative mobility, give fabric softness and the high strength retention of tearing, prevent the tearing strength decline phenomenon that the conventional anti-crease finishing method of fabric easily causes. Method provided by the invention has that operation is simple and direct, working (machining) efficiency is high, environmental protection, feature that economic benefit is high. Good, soft, the powerful nothing of wrinkle resistance of goods obviously declines, tearing strength retentivity is good, can be used for clothes, bedding etc.

Description

A kind of based on the crosslinked fabric anti-crease finishing method of spray process point-like
Technical field
What the present invention relates to is a kind of based on the crosslinked fabric anti-crease finishing method of spray process point-like, belongs to textileRear finishing technique field.
Background technology
Work, the life style of the high rhythm of modern society have proposed high request to the performance of easily arranging of clothes. ClothesRequirement has good wrinkle resistance, after washing, still keeps smooth, does not affect the appearance. Therefore some resists selfThe bad fabric of wrinkle property needs first to carry out anti-crease finishing making before clothes.
Relative slippage easily occurs fiber molecule interchain is the major reason that fabric produces fold. Cotton, hair, silk,The fibers such as fiber crops, viscose glue pure spun and blend fabric all easily produces fold. The principle of anti-crease finishing is mainly fixing pointThe relative position of subchain, prevents and reduces the generation of slippage between strand.
Current industrialized anti-crease finishing method mainly contain roll-dry-roasting technique, foam finishing and tide crosslinked etc. Roll-baking-roasting technique is traditional anti-crease finishing technique, and what the fabric obtaining existed feel to harden, strength loss is large asksTopic, the wearability of clothes is had to certain harmful effect, and the finishing agent consumption of padding method is large, after padding, knitsThe liquid carrying rate of thing is high, causes preliminary drying, to cure energy consumption high, do not meet the theory of environmental protection and economy. AndFoam finishing, tide are crosslinked etc. owing to there being the problems such as complex procedures, process time are long, have affected its popularization.
In order to overcome now methodical deficiency, researcher has carried out a large amount of explorations and research. Granted publication numberFor patent of invention " for spraying method and the spray thrower of fabric finishing ", the Granted publication number of CN101974834BFor utility model patent " array electrostatic spraying system and equipment for dyeing and finishing thereof " and the mandate of CN201915239UNotification number is the utility model patent " for the spray thrower of fabric finishing " of CN201793915U, and one is providedNew finishing agent applies mode and application devices.
In order to provide, a kind of operation is simple, environmental protection, good in economic efficiency, and product can have concurrently good crease-resistantEffect, feel and powerful fabric anti-crease finishing new technology, on fabric, point-like applies crease-shedding finishing agent, crosslinkedNumerous even, the intensive and discontinuous crosslinking points of rear formation. Point-like crosslinked fabric has good wrinkle resistanceMeanwhile, can keep good brute force and feel: crosslinking points provides good wrinkle resistance, between crosslinking points and crosslinking pointsSegment provide good flexibility and segment mobility for fabric. The particle diameter of spray droplet, spacing, sprayThe parameters such as amount are controlled, can control flexibly operating mode according to fabric situation and processing request. Spray the total of finishing agent usedAmount is less than padding method, can effectively reduce the use amount of the chemical substances such as crease-shedding finishing agent, meets people health is got overCarry out higher requirement. The liquid carrying rate of fabric is lower, can effectively reduce heat treatment energy consumption, meets energy-saving and emission-reduction requirement.The method has serialization production, process velocity is fast, and environmental pollution is little, equipment investment is few, economic benefit is highAdvantage.
Electron beam to irradiate crosslinked technology is nearly decades of full-fledged technology, and industrial applications is in multiple necksTerritory, is the manufacturing process that a kind of efficiency is high, public hazards are few, economic benefit is high, has widely in the crease-resistant field of fabricApplication prospect. Point-like is applied to crosslinking agent and electron beam to irradiate crosslinked is used in conjunction with, can further reduce fabric anti-The energy consumption that wrinkle arranges, promotes fabric property, improves process velocity.
Summary of the invention
