PATENT? OFFICE AND HERBERT PLATT, OF CUMBERLAND,
OF DELAWARE TEXTILE MATERIAL AND METHOD OF PREPARING THE SAME No Drawing. Application filed April 2,
This invention relates to textile materials, such as yarns or fabrics, made of or containing organic derivatives of cellulose and having therein or thereon a substance that causes the same to scorch at temperatures below their melting points.
An object of our invention is to incorporate in textile materials containing organic derivatives of cellulose, substances that lower the scorching temperature of the same. Other objects of our invention will appear from the following detailed description.
Unlike textile materials made of cotton, natural silk, wool or reconstituted cellulose, textile materials containing organic derivatives of cellulose tend to melt when they are subjected to an iron or calender that is at too high a temperature. While the safe ironing temperature of organic derivatives of cellulose material is no lower than the safe ironing temperature of natural silk, these organic derivatives of cellulose textile materials do not scorch at temperatures substantially below the temperature at which they tend to melt, and therefore the launderer does not have the warning of scorching to indicate too high temperatures of the iron or calender as he does in the case of the laundering of other textile materials.
We have found that if certain substances are incorporated in the textile material con taining organic derivatives of cellulose, either prior or subsequent to its formation, the temperature at which it scorches is reduced considerably below the temperature at which it melts, and therefore if too hot an iron or calender is applied to such textile material, it tends to scorch and thus oifer a warning to the operator that the iron is too hot, so that the melting of .the textile material may be avoided.
In accordance with our invention, we prepare textile materials containing organic derivatives of cellulose which tend to scorch at temperatures lower than at which they melt, by incorporating therein or thereon, either prior or subsequent to their formation, substances which cause such textile materials to scorch before they tend to melt.
The textile material may contain any suit- 1929'. Serial No. 352,046.
able organic derivative of cellulose such as organic esters of cellulose or cellulose ethers. Examples of organic esters of cellulose are cellulose acetate, cellulose formate, cellulose propignate and cellulose butyrate, while examples of cellulose ethers are ethyl cellulose,
tile material either before or after its forma-.
tion. Thus the substance may be added to the solution of the organic derivative of cellulose prior to its extrusion through orifices into a drying atmosphere or into a precipitating bath to form the filaments or yarn.
On the other hand, the yarn, after its formation, may be subjected to a solution or paste containing the substance that tends to cause scorching. If desired, the fabric containing organic derivative of cellulose yarn may be treated with the substance that tends to cause scorching.
Any suitable organic substance that does not deleteriously affect the textile material containing the organic derivatives of cellulose, and which tends to lower the scorching point of such textile material, may-be used. This substance may be an oil such as olive oil, an organic salt such as the acetates of sodium, potassium, or aluminum, soaps such as the oleate or stearate of sodium or potassium, starches, albumen, gelatin, latex, or a wax such as beeswax or spermaceti. Some of these substances, such as olive oil, are best incorporated in the spinnin solution, while some of the others may well lie applied to the yarn or fabric. i
If such substances that tend to cause scorching are applied to the yarn or fabric, after the formation of the same, often swelling agents such as the thiocyanate of ammo nium, sodium or potassium, or formic acid of the textile material, the soluble salt is not removed to a substantial extent.
If the textile material contains organic esters of cellulose, further advantages may be obtained by saponifying the surfaces of the filaments or yarns of the organic esters of cellulose to increase the safe ironing temperature thereof. Thus the yarn or fabric may be subjected to a dilute alkaline bath until it sufiers a loss in weight of from 3 to 10% or more by saponification. Other methods of obtaining surface saponification of the filaments or yarns may also be employed; This surface saponification of the textile material may be caused to take place either prior or subsequent to the incorporation of the substance that tends to lower the scorching temperature. While the surface saponfication may be produced in any suitable manner, we prefer to employ the processes described in our copending applications Nos. 248,558 filed Jan. 21, 1928; 268,365 filed April 7, 1928 and 303,600 filed Sept. 1, 1928.
Textile materials when made or treated in accordance with our invention scorch at temperatures of 10 to 30 C. or more lower than the temperature at which they tend to melt. If an attempt is made to iron such textile materials with an iron or calender that is too hot, ample Warning will be given by the tendency of the textile material to scorch first.
In order further to illustrate our invention but without limiting the scope thereof, the following specific examples are given.
Example I A fabric consisting wholly of cellulose acetate yarn is scoured and then subjected to a bath'contain ing about 0.5 grams per litre of caustic soda in such a manner as described in our applications Nos. 248,558 and 268.365 that it suffers a loss of weight of about 6% by saponification. This treatment materially increases the temperature at which the fabric may be ironed safely. The sotreated fabric is then subjected on a jig to an aqueous bath containing 15 grams per litre of sodium acetate and 10 grams per litre of egg albumen, the temperature of the bath being 60 and the time of treatment being about 10 minutes. The material is then dried on a tenter at a temperature of about 78 to 85 C. to cause the coagulation of the albumen.
The fabric so treated scorches at a temperature considerably below that at which it melts. Even afterthe fabric is washed for 10 minutes at C. in a soap bathcontaining 5 grams of soap per litre, rinsed and dried, the materials tending to cause scorching are retained so that the Washed fabric still has a reduced scorching temperature.
Example I I A fabric consisting Wholly of cellulose acetate yarn and partially saponified as described in Example I is treated'on a jig with an aqueous solution containing 15 grams of sodium acetate per litre for about 15 minutes. It is then dried on a tenter and is found to have a materially lower scorching temperature than the fabric that is not treated.
