Description
Дл получени несмываемых аппретов известно применение простых и сложных эфиров целлюлозы, растворов целлюлозы и др. Отличительной особенностью предлагаемого способа вл етс то, что в качестве аппрета примен ют раствор целлюлозы в-Цинкате (HZnOa), которым пропитывают волокнистый материал, после чего материал следует обработать кислотой и промыть водой.The use of cellulose ethers and esters, cellulose solutions, etc. is known for obtaining indelible finishing agents. A distinctive feature of the proposed method is that a cellulose solution in Zincate (HZnOa) is used as a coupling agent, which is impregnated with fibrous material, after which the material should be treated acid and rinse with water.
Пример. Отбеленный линтер или мелкоразмельченную целлюлозную пульпу с в зкостью 10-30 сантипуаз ввод т небольшими порци ми Б раствор цинката натри , охлажденного до температуры -5° С или +5° С.Example. Bleached linter or finely ground cellulose pulp with a viscosity of 10-30 centipoise is introduced in small portions B of a solution of sodium zincate, cooled to a temperature of -5 ° C or + 5 ° C.
Раствор цинката готов т следующим образом: ПО г едкого --натра раствор ют в 110 ли воды ив полученный раствор постепенно внос т 25 г окиси цинка, нагревают его до кипени и, когда раствор сделаетс прозрачным, довод т объем раствора до литра.The zincate solution is prepared as follows: After a gum-free solution, it is dissolved in 110 liters of water, and the resulting solution is gradually introduced 25 g of zinc oxide, heated to boiling and, when the solution is clear, bring the volume of solution to a liter.
Растворы линтера или целлюлозной пульпы в цинкате через Z9- 45 мин. после начала растворени получаютс прозрачными и в зкими 5Solutions of linter or cellulose pulp in zinc in Z9- 45 min. after initiation of dissolution, they are clear and viscous. 5
и не содержат нерастворившихс волокон,and do not contain undissolved fibers,
4%-ный раствор целлюлозы вследствие его большой в зкости мало пригоден дл аппретировани ; более подход щими вл ютс 2%-ные растворы, которые приготовл ют следующим образом.Due to its high viscosity, 4% cellulose solution is not suitable for dressing; more appropriate are 2% solutions, which are prepared as follows.
В котел с мешалкой загружают 490 кг охлажденного до температуры 5° С цинката и при непрерывном перемешивании небольшими порци ми прибавл ют 10 кг отбеленного линтера или целлюлозной пульпы и при этой температуре и работающей мешалке дают выдержку в течение 45 мин. - I часа.490 kg of zincate cooled to 5 ° C are charged to the stirred boiler and 10 kg of bleached linter or cellulose pulp are added in small portions with continuous stirring and the holding is allowed to hold for 45 minutes at this temperature and operating mixer. - I o'clock.
Контроль за полнотой растворени волокна производитс путем просмотра капли аппрета под микроскопом . Прозрачный, однородный, в зкий и не содержащий нерастворимых волокон аппрет может без изменений хранитьс при комнатной температуре в течение %-3 дйей. Нанесение аппрета на ткань производитс обычным способом. Ткань, пропитанна аппретом и отжата на плюсовке или джигере, поступает дл коагулщии и закреплени в кнс67Monitoring for the complete dissolution of the fiber is carried out by viewing a drop of a size under a microscope. A clear, uniform, viscous, and non-insoluble sizing compound can be stored unchanged at room temperature for% -3 dyy. Applying the dressing on the fabric is made in the usual way. The fabric impregnated with a dressing and pressed on a pad or jigger is supplied for coagulation and fixation in kn67
лотную ванну, а затем тщательно промываетс водой до исчезновени кислой реакции (по метилоранжу или конго). После чего ткань сушат и, если это необходимо, подвергают ширению и каландированиго.The lot bath and then thoroughly washed with water until the acid reaction disappears (according to methyl orange or Congo). After that, the fabric is dried and, if necessary, subjected to brooding and calendering.
Преимущества предлагаемого способа следующие;The advantages of the proposed method are the following;
а)изготовление несмываемого аппрета не нуждаетс в сложной аппаратуре и дефицитных материалах и может быть легко осуществлено непосредственно на красильно-отделочной фабрике;a) the fabrication of an indelible finish does not require complicated equipment and scarce materials and can be easily carried out directly at the dyeing and finishing factory;
б)отпадает необходимость в трудоемких и сложных процессах мерсеризации целлюлозного сырь , этерификации алкалицеллюлозы, тре .бующих дл своего осуществлени организации специального производства со сложной аппаратурой;b) there is no need for labor-intensive and complex processes for the mercerization of cellulosic raw materials, the esterification of alkaline cellulose, which is required for its implementation of the organization of special production with complex equipment;
в) предлагаемый аппрет по своей стойкости к многократным стиркам не уступает лучшим маркам несмываемых-аппретов , как-то: деллину, тилозе и оксиэтиловому эфиру целлюлозы .c) the proposed finish in terms of its resistance to repeated washing is not inferior to the best brands of indelible finishing agents, such as: delline, tylose and hydroxyethyl cellulose ether.
Предмет изобретени Subject invention
Способ получени несмываемого аппрета, отличающийс тем, что волокнистый материал, например , ткань, пропитывают раствором целлюлозы в цинкате щелочного металла , обрабатывают кислотой и промывают .A method for producing an indelible finish, characterized in that the fibrous material, for example, a fabric, is impregnated with a solution of cellulose in alkali metal zincate, treated with acid and washed.
