Изобретение относитс к текстиль ной промышленности и может быть использовано при отделке текстильных материалов. Известен способ аппретировани целлюлозных тканей обработкой их 2,5-5%-ным латексом сополимера на основе акрилонитрила, а именно разбавленным до указанной концентрации латексом СКС-40ГП,с последукхцей термообработкой ij . Недостатками способа вл ютс не высока износоустойчивость и снижение белизны аппретированных тканей. Кроме того,, указанный латекс нал пает на оборудование при сушке и легко смываетс с тканей при стирка Цель изобретени - повышение износоустойчивости целлюлозных тканей Поставленна цель достигаетс за счет того, что при аппретировании целлюлозных тканей обработкой их 2,5-5%-ным латексом сополимера на основе акрилонитрила с последующей термообработкой, используют латекс на основе привитого сополимера акрилонитрила и метилакрилата в соотношении 50-90:10-50 соответст ,венно, на поливиниловом спирте. Синтез латекса провод т методом привитой эмульсионной полимеризации прививкой на поливиниловом спирте, растворенном в воде, акрилонитрила и метилакрилата в соотношении 50-90: : 10-50 при температуре 60-120 С в течение 60-180 мин в присутствии инициаторов - персульфата аммони и метабисульфита натри и комплексообразовател трилона Б. Поливиниловый спирт ввод т в количестве 20 вес.% мономеров. Полученный латекс разбавл ют при комнатной температуре водой до необходимой концентрации . Дл повышени белизны тканей в латекс ввод т оптические отбеливатели . Дл придани ткан м малоусадочности к латексу можно добавл ть карбамол ЦЭМ. Пример 1. Хлопчатобумажную ткань пропитывают 2,5%-ным (в пересчете на сухой остаток) латексом, синтезированным при соотнс иении акрилонитрила и метилакрилата в реакционной смеси 90:10, содержащим дополнительно 0,02 вес.% оптического отбеливател . Пропитку провод т 5-10 с при комнатной температуре. затем ткань отжимают до привеса 100 и сушат при 100-14 Ос. Свойства обработанной ткани приведены в таблице. Пример 2. Хлопчатобумажную ткань пропитывают 5%-ным латексом, синтезированным при соотношении акрилонитрила к метилакрилату 75:25, (Содержащим 0,05% оптического отбели тел . Параметры обработки те же, цто и в примере 1. Показатели обработанной ткани приведены в таблице. Пример 3. Хлопчатобумажную ткань пропитывают 2,5%-ным латексом, синтезированным при соотношении акрилонитрил:метилакрилат 50:50, содержащим 0,05% оптического отбеливател . Параметры обработки те же, что и в примере 1. Свойства ткани приведены в таблице.The invention relates to the textile industry and can be used in the finishing of textile materials. There is a known method of finishing cellulose fabrics by treating them with a 2.5-5% acrylonitrile-based copolymer latex, namely SCS-40GP latex diluted to a specified concentration, with subsequent heat treatment ij. The disadvantages of the method are not high wear resistance and reduced whiteness of the fitted fabrics. In addition, the specified latex falls on the equipment when drying and is easily washed off the fabrics during washing. The purpose of the invention is to increase the durability of cellulose fabrics. The goal is achieved due to the fact that when finishing cellulose fabrics by processing them with 2.5-5% by weight copolymer latex on the basis of acrylonitrile, followed by heat treatment, use a latex based on the graft copolymer of acrylonitrile and methyl acrylate in a ratio of 50-90: 10-50, respectively, on polyvinyl alcohol. Synthesis of latex is carried out by the method of graft emulsion polymerization by grafting on polyvinyl alcohol, dissolved in water, acrylonitrile and methyl acrylate in a ratio of 50-90: 10-50 at a temperature of 60-120 ° C for 60-180 minutes in the presence of ammonium persulfate and metabisulphite initiators sodium and complexing agent Trilon B. Polyvinyl alcohol is introduced in an amount of 20 wt.% of monomers. The resulting latex is diluted at room temperature with water to the desired concentration. To increase the whiteness of the fabrics, optical brighteners are introduced into the latex. Carbamole CEM can be added to give latex tissue a small size. Example 1. Cotton fabric is impregnated with 2.5% (calculated on the dry residue) latex synthesized by the ratio of acrylonitrile and methyl acrylate in a 90:10 reaction mixture, containing an additional 0.02 wt.% Optical bleach. Impregnation is carried out for 5-10 s at room temperature. then the fabric is pressed to weight gain 100 and dried at 100-14 OC. The properties of the treated fabric are shown in the table. Example 2. Cotton fabric is impregnated with 5% latex synthesized at a ratio of acrylonitrile to methyl acrylate 75:25, (containing 0.05% optical bleaching phone. The processing parameters are the same as in example 1. The values of the treated fabric are shown in the table. Example 3. Cotton fabric is impregnated with 2.5% latex synthesized with an Acrylonitrile: Methyl acrylate ratio of 50:50 containing 0.05% optical brightener. The treatment parameters are the same as in Example 1. The fabric properties are shown in the table.
Несминаемость определ ют по углу раскрыти испытуемой полоски на приборе см тиеметре. Стойкость к истиранию определ ют на приборе ИТ, а прочность на разрыв на разрывной машине РТ-250.Injuryability is determined by the opening angle of the test strip on the device, see meter. Abrasion resistance is determined on the IT device and the tensile strength on the RT-250 tensile testing machine.
Дл определени светостойкости образцы аппретированной ткани подвергают инсол ции в течение одного мес ца, а затем определ ют прочность на разрыв на разрывной машине РТ-250.To determine the light fastness, the samples of the finished fabric are insulated for one month, and then the tensile strength of the RT-250 tensile testing machine is determined.
Таким образом, предлагаемый способ аппретировани обеспечивает повышение износостойкости и светостойкости тканей без снижени степени белизны при хорошем наполненном грифе и высокой устойчивости аппрета.Thus, the proposed dressing method provides an increase in the wear resistance and light resistance of fabrics without reducing the degree of whiteness with a good filled neck and high stability of the finish.
