Definitions

• This invention relates to novel textile fabrics and to processes for making the same. More particularly, this invention relates to a process whereby natural or artificial cellulose materials in the form of fibre, yarn, or woven fabric, are given novel and useful properties.
• cotton muslin or voile is preferably treated with one-third to one mol. of ethylene oxide, per-CeHioOs unit, the amount of reagent used depending on the nature of the fabric and on the required degree of stiffness in handle.
• the amount used may run considerably higher than that indicated above, and may even exceed 10 mols of ethylene oxide per CsHwOs unit. It is found, however, that when large proportions of ethylene oxide enter into combination, the fabric obtained is tender.
• the treatment with ethylene oxide may be direct, with gaseous ethylene oxide, or may be carried out by using a solution of ethylene oxide in an inert solvent, for instance dioxane, acetone. benzene, tetrachlorethane, or carbon tetrachloride.
• an inert solvent for instance dioxane, acetone. benzene, tetrachlorethane, or carbon tetrachloride.
• Propylene oxide and glycide being liquids at room temperature, are used as such, either at ordinary or elevated temperature, but preferably they are used as solutions in the solvents mentioned.
• the products obtained according to this invention can then be regarded as consisting of cellulose fibres carrying a layer or skin of treated cellulose.
• the product obtained may be further modified as to surface finish and dyeing qualities by treating the same with acylating agents according to the methods usually employed in acylatlng ordinary cellulosic material to produce a cellulose esterinaterial.
• acylating agent is an acetylating agent it has been found that acetylation readily takes place, so that the process can be carried out under mild conditions.
• the fabric, yarn, etc. may also be given a subsequent mercerizing treatment, whereby the finish is improved, particularly in respect of transparency.
• the dyeing properties of the products of the invention differ from those of the starting materials in that they possess altered afiinity for certain dyestuffs.
• Example 1 Finely woven bleached cotton fabric 14 parts is mercerized by immersing it under tension according to the customary procedure in 50 Tw. aqueous caustic soda. The mercerized fabric is then wrung out until there remains in the fabric 25 parts of mercerizing liquor. The moist fabric is then suspended in a chamber into which 3.8 parts (1 molecular proportion per 1 molecular proportion of cellulose reckoned as Cal-[1005) of ethylene oxide are passed. The chamber is closed and left for 17 hours.
• the fabric is then washed and dried.
• the product is a stiff organdie fabric, but becomes limp when wet. It is readily dyed by direct cotton dyestuffs.
• Example 2 The product of Example 1 is put into a bath, kept at 95 (1., composed of a mixture of 20 parts of dry pyridine and 80 parts of acetic anhydride. The material is subjected to the action of the bath for two hours. It is then washed and dried.
• Emample 3 Closely woven cotton fabric (162'parts) is mercerized in aqueous caustic soda of 50 Tw. removed, pressed and treated with 44 parts of ethylene oxide in a closed vessel for 17 hours at room temperature. The fabric is washed and dried, being parchment-like, but pliable.
• Example 4 Cotton muslin (52 parts) is treated with 50 Tw. caustic soda as described in previous examples, pressed and treated with 11 parts of ethylene oxide, moi. per CsHloOs unit) in a closed vessel for 17 hours at room temperature. The material is then washedin water and dilute acetic acid (1%), rinsed in water and dried. A fabric with an organdle type of finish and of good color is obtained.
• Example 5 Cotton muslin (14 parts) is treated with alkali as described in Example 1, immersed in a solution of ethylene oxide (30 parts) in dioxan (500 parts) and left for 20 hours at ordinary temperature (20 C.). The fabric is then washed and dried. A material is so obtained which is slightly stiffened in handle, more transparent than the original material and of good color.
• Example 6 Cotton muslin (14 parts) is pretreated with alkali as previously described, immersed in a solution of ethylene oxide parts) in benzene (500 parts) and left at room temperature for 20 hours. The fabric is washed and dried, a slightly stiffened gauze-like material being obtained,
• propylene oxide may be used instead of ethylene oxide.
• the subsequent mercerization is carried out according to the usual procedure for mercerizing under tension.
• the product of Example 6 there is an increase in transparency and the appearance is improved.
• Example 7 Cotton muslin parts) is placed in aqueous sodium hydroxide (50 Tw.) for 5 minutes and the excess alkali is removed by squeezing.
• the fabric is then immersed in a solution (50 parts) consisting of 2 parts of glycide in 48 parts of acetone and left at room temperature for 15 hours. After washing and drying, the fabric is considerably stiffened and has an organdie" finish.
• Example 8 Cotton muslin parts) is pretreated with alkali as described in the preceding example.
• the temperature at which the reaction between the alkylene oxide and mercerized cellulosic fabric is effected may also be varied, it being understood, of course, that higher temperatures result in increased speed of reaction and that the time of reaction must be decreased accordingly to obtain the same degree of reaction, and of finish in the fabric.
• the quantity of ethylene oxide may vary considerably depending on the desired finish or on whether a solvent is employed. In the latter case, the large quantity of solvent reduces the concentration of the ethylene oxide at the zone of reaction, that is the surface of contact between the fabric and the ethylene oxide; therefore a larger total quantity of the latter is permissible.
• a process for producing an organdie fabric which comprises treating a cellulosic fabric in the presence of alkali with an alkylene oxide compound of the general formula CHz-CH-R wherein R stands for H, CH3 or CHzOH, in proportion of from 5 to 1% moles of the latter per unit of CBHlOOB in the fabric, and under conditions equivalent to about room temperature and a time from about 17 to about 20 hours.
• Cellulose fabric containing mercerized fibers partially etherified under alkaline conditions by reaction with ethylene oxide in the ratio of one mole of cellulose to from one-third to one and one-half moles of ethylene oxide dissolved in an inert organic solvent, said fabric having the finish and feel of an organdie fabric and having an afiinity for direct cotton dyestuffs.
• Cotton fabric containing fibers which have been modified by treatment with aqueous caustic soda or not less than 11% strength and then by treatment under alkaline conditions with ethylene oxide in the ratio of one mole of cellulose to from one-third to one and one-half moles of ethylene oxide, said fabric having the finish and feel of an organdie fabric and having an afiinity for direct cotton dyestufls.
• a process for modifying the surface qualities of textile cellulosic fabric which comprises subjecting the same to a treatment including as its first step treatment of the fabric with aqueous alkali of a strength comparable to those employed in mercerization of cotton, and as a second step the further treatment of said fabric with an alkylene oxide of the general formula wherein R. stands for H, CH3 or CHzOH, in low concentration ln'the zone of reaction and under reaction conditions equivalent to about room temperature at a time of about 1'7 to about 20 hours.
• a process of producing a woven textile fabric which comprises treating a mercerized woven cellulose fabric with ethylene oxide in proportion not exceeding 1 mols per unit of CaHmOs in the fabric, dissolved in an inert organic solvent, and under conditions equivalent to about room temperature and a time of from about 17 to about 20 hours.
