Definitions

• This invention relates to the treatment of waste spun or woven material arising in textile works, garment factories or the like or which are obtained from rag merchants and object to provide an improved method of treating such waste containing silk, wool, artificial silk, cotton or other fibres in order to obtain therefrom fibres adapted to be respun into yarns with or without the addition of virgin fibre.
• the invention is mainly concerned with the treatment of waste spun or woven material containing artificial silk in connection with which the known processes of treating the same have resulted in crude and unsatisfactory results in that the original lustre oi the artificial silk is lost and spinners have experienced dificulty in treating the cardedartificial silk fibre.
• the waste is subjected to the action of aqueous detergents and before or after treatment in an opening carder is treated with a weak acid, for instance boric acid, and dextrine or soluble starch or the like.
• a weak acid for instance boric acid, and dextrine or soluble starch or the like.
• the textile waste After being subjected to the action ot a detergent the textile waste may be treated with a solution of a neutral salt for instance, sodium sulphate.
• a neutral salt for instance, sodium sulphate.
• the waste treated consists of or contains a material proportion of artificial silk the same is advantageously subjected to the acacid ammonium phosphate in addition to oric acid.
• bales which will be opened up and may be disinfected, for instance, by the aid of formaldehyde.
• the waste may also be beaten to remove .dust prior to treatment with a detergent.
• Waste material after treatment to remove dust and washing with a detergent maybe treated with a solution of sodium sulphate and dried, the washed and dried material being then cut up into suitable sized fragments which by means of machines of generally known character are disintegrated or opened up, the fibrous material obtained being carded and subjected to the action of a solution containing essentially a weak acid, 0
• waste rags consisting wholly or mainly of artificial silk
• the rags may be freed from dust or dirt by mechanical processes, sorted with the aid, for instance, of an endless belt conveyor, cut'up into pieces of 2 or 3 inches in length by a rag-cutting ma- 0 chine, such for instance as is used in a fine paper factory.
• the cut rags are then opened up by treatment with an opening carding machine, washed in warm water suitable detergents, for instance, soap flakes, dyed if necessary, to obtain a uniformly coloured product, and dipped into a solution con taining a weak acid and a proportion of solubis starch.
• suitable detergents for instance, soap flakes
• This dipping may be carried out by treating the fibre with a solution containing 1 oz. of boric acid and oz. soluble starch to each 10 gallons of cold water and as indicated this solution may also contain acid ammonium phosphate.
• the waste is taken out, lightly pressed and cotton, the solution em- 5 the invention, the solu- 70 with the addition of 85 treatment to which 35 the action of aqueous so treatin eo per litre acid ammonium phosphate,
• Yarns of fine counts can be spun from the finished fibres on a cotton spinning machine while the coarser yarns may be'spun on worsted spinning machines and in the spun condition the yarns may be used for difi'erent purposes either alone or in association with real silk, cotton, wool or linen so as to obtain products of high or low lustre.
