Description
Technical field
The present invention relates to a kind of preparation methods of pretreating reagent containing spandex fabric, belong to technical field of textile auxiliary agent.
Background technique
Since the 1980s, due to the exploitation of spandex core-covered silk and coating technology, make spandex in socks processing and
Band class application field expands rapidly, and spandex yield suddenly increases.To the nineties, wrap yarn, the covering yarn, conjunction of spandex and other fibers
Fabric of twisting thread has been greatly developed, oneself gradually replaces cotton, polyester-cotton fabric, and one jumps and becomes current garment material, especially
It is the first choice of fashion material.Nowadays, due to weaving, knitting technology continuous development, spandex using more and more extensive, demand
Growth trend is also always maintained at yield.Spandex fibre has many advantages, such as that good elastic recovery, extension at break and breaking strength are high.
Comfortable and easy to wear containing clothes made of spandex face fabric, Chinese PU Fiber is mainly used in terms of being knitted woven fabric containing elastic fiber.With weaving, needle
Knit the development of technology, spandex has developed to dancing sportswear, sweater, Insulation shirt, worsted fabric etc. using increasingly extensive,
Supply falls short of demand for spandex fibre.
By the development of over half a century, global Surfactant Industry has become mature.Textile industry in recent years is raw
Production center is gradually shifted to Asia from traditional Europe, the U.S. due to well-known, so that the weaving of Asia
Auxiliary agent demand rapid growth.Whole world textile auxiliary has nearly 100 classes, produces nearly 1.6 ten thousand kinds, annual output about 410
Ten thousand tons.
Spandex is often used its long filament multifilament, much thinner than rubber thread, thus adapt to knitwear, woven fabric etc. it is a variety of plus
Work.After spandex generally uses naked silk and polyamide fibre or other fibers (cotton, hair, fiber crops, silk, chemical fibre etc.) that yarn is made together, warp knit,
Processing weaving is carried out in the equipment such as weft knitting, loom, since naked spandex yarn elongation is larger, sliding capability is bad, therefore multi-purpose packet
Cover yarn, packet forms such as yarn, folded yarn of growing sturdily weave.Its main feature is that the content of spandex less (2%~25%) can give full play to it
Elastic reaction.Using spandex thread high resiliency and wearability the characteristics of, various elastic bands, waistband can be processed；Industrially may be used
Small-sized or light-duty belt or transmission belt is made with it；In terms of medical supplies, it can be made into elastoplast and the shield of scalded patient
Band or shield.Various labor protection gloves are made using spandex oil resistant, organic solvent-resistant, chemical resistance, its use
Service life considerably beyond common work gloves, very by the welcome of worker.Furniture decoration cloth, automobile interior trim, wig can also be made
Cap etc. provides great exploitation potential and economic benefit for fields such as clothes, medical supplies, hotel article and industrial cloth linings
Upgraded product.
The pre-treating technology of the textile containing spandex is different and different with kind, and most important processing includes loose and concise.Contain
The textile containing spandex of cotton fiber also needs to carry out mercerising and bleaching；It is tubular knitted also to carry out the processing such as open-width.
Some chemical companies, which specially develop, is suitable for the scouring agent containing spandex.Such as it is Japanese bright at chemical industrial company
Minexup-100；Solar corona chemical company develops two kinds of nylon/polyurethane fiber pretreating reagent, and PU-800 can be effectively removed
And dispersed metal component, specking caused by preventing because of metal ion.PU-252 can effectively remove silicone oil, finish, stone on fabric
Wax etc. prevents them from adhering to again by good emulsion dispersion.
Domestic scouring agent: scouring agent MOL-201, without phosphorus multi-functional scouring agent, the low alkaline-resisting silkete penetrating agent ADVANWET of bubble,
Shin-gosen scouring agent AV-SCOUR81, scouring agent TF-108, scouring agent TF-109, shin-gosen scouring agent MS, solvent type are concise
Agent SSA etc..The concise bleeding agent EA-11A of the low temperature oil removing of Yi Xin new high-tech material Co., Ltd；The limited public affairs of Ningbo Orco textile raw material
The spandex of department deoils scouring agent OKESOL-A300；HK-G22 spandex degreaser etc..They are all strong concise of some abilities of deoiling
Agent has very strong emulsifying capacity to finish, and generally prevents the ability that greasy dirt is infected with again with very strong.
China also develops many novel environment-friendly auxiliary agents in recent years, such as scouring agent ZS-95, hydrogen peroxide stabilizer
GJ-201, alkyl glycosides analog assistant, biological enzyme formulation ZS-200, main auxiliary agent manufacturing enterprise concentrate on Jiangsu, Zhejiang
The Guangzhou and.The ratio between textile auxiliary and fiber production world average level are 7:100, the industry such as the U.S., Germany, Britain and Japan
Developed country is 15:100, but the ratio between the current textile auxiliary yield in China and fiber production only have 4:100, with world level phase
Than the consumption level of China's textile auxiliary is also relatively low, and low-grade and universal auxiliary agent is superfluous, possesses independent intellectual property right
Auxiliary agent it is less.In addition, the level due to basic material is not high, some top grade tailored version auxiliary agents are developed slowly.Textile auxiliary
Product about 80% is using surfactant as raw material, and about 20% is functional aid.The textile auxiliary kind that China is able to produce
Nearly kind 2000, often produced has more than 800, and principal item has 200 or so.Textile industry especially dyeing and finishing industry by
National authorities are determined as heavy polluted industry, and Devoting Major Efforts To Developing meets the environmentally friendly textile auxiliary of ecodevelopment, to raising auxiliary agent row
The whole competitiveness of industry, promotes textile auxiliary product quality and technical level is particularly important, is the key that industry value chain.
In knitted fabric dyeing and finishing, often encounters cloth cover greasy dirt, contamination, color stain, dyeing defect, silicone oil spot etc., cause product matter
Amount reduces, and some can not even return something for repairs.For that purpose it is necessary to find with height emulsification, disperse, the degreaser of solvability.Spandex
In-O-CO-NH-group will receive the attack of alkali and effective chlorine, therefore in preceding processing, the concentration of alkali must be controlled
It is good, in practice it has proved that, with the increase of alkali concentration and the raising of temperature, the elastic loss of spandex increases, and temperature is higher, elasticity
Loss increases with concentration and incremental degree is also bigger.
In fabric scouring, the scouring agent of early application is generally fairly simple, and composition and function are also relatively simple, some sides
It permeates again, such as penetrating agent JFC；Some stresses to emulsify, such as peregal；Some stresses washing, such as soap, 601 detergent (alkyl sulphur
Sour sodium), 209 detergent (oleoyl N-methyltaurine sodium) etc..The environment-friendly type highly effective scouring agent developed in recent years, has still followed 20
Requirement of the 80~nineties of century to scouring agent, it is such as more efficient although some new techniques put forward higher requirements scouring agent
To shorten process time；Higher alkali resistance is to adapt to cold pad--batch or a few unification techniques etc., but the composition of scouring agent is still with yin
Based on the compounding of ionic surface active agent and nonionic surfactant, only compounded technology more attains maturation, raw materials used to have sent out
Great changes are given birth to.The environment-friendly type highly effective scouring agent of a new generation is most of by fatty alcohol polyoxyethylene ether, lauryl alcohol polyoxyethylene
The surfactants such as ether sulfuric ester, Teepol alkyl polyglycoside, fatty acid methyl ester sulfonate, Tea Saponin are compounded.
Since spandex itself has very strong adhesion property, difficulty when in order to avoid post-processing process, than general synthetic fibers
More finishes are enclosed, the oil applying rate of spandex is generally 2%~6% or so.Spandex is containing miscellaneous few, the mainly ash of finish and contamination
Dirt etc., since spandex is a kind of elastomer, oil absorption is stronger than other fibers, and polyether-type class oil absorption is again stronger than polyesters.
So the purpose of spandex Pretreatment of textile mainly removes degreaser.When textile is less containing spandex, the influence of finish is less
Obviously, and when amount containing spandex is high in textile, such as swimming suit etc., the finish of spandex often brings to Pretreatment of textile many tired
It is difficult.
Scouring agent currently on the market usually carries out under alkaline condition when concise, alkali concentration size and effect pass of deoiling
It is very big, and the alkali resistance of spandex is very poor, therefore in order not to hurt the performance impairment of spandex, especially it is necessary to develop to be suitble to containing ammonia
The pretreating reagent of synthetic fibre fabric, it is good to prepare one kind effect of deoiling, to whiteness and the equal significant effect of capillary effect containing spandex fabric；Have good
Permeability, small pretreating reagent is influenced on the elastic property containing spandex fabric.
