• ABSTRACT A method for processing polyamide fibrous material, especially nylon products, wherein the fibrous material is treated with a solution or dispersion including TiCl and polyethylene, thereby providing the material with full-dullness and nonwaxy touch.
• Polyamide fibers are highly superior in their strength and dyeing characteristics, and therefore find their vast and broad availability in the fields of industrial application; domestic appliances and especially clothing products.
• Various and profound investigations have been made toward providing, in addition to said superior and desirous characteristics, other various characteristics which are peculiar to common natural fibers such as wool, cotton and the like, to polyamide fibers which are defective on account of its remarkable transparent and waxy appearance and lack ot moisture-absorbing characteristic.
• polyamide fibers are utilized for fabrics for clothing, inferior appearance, touch, handling and wearing contact are necessarily encountered.
• the surface conditions of polyamide fibers are modified by being subjected to the action of certain reagents such as hydrochloric acid, sulfuric acid, zinc chloride or the like.
• certain reagents such as hydrochloric acid, sulfuric acid, zinc chloride or the like.
• the technical reason for the accentuated stiffness in the surface-conditioned polyamide fibers in the above sense can be attributed to the fact that at least a part of the polyamide fibers is dissolved by contact with the conditioning reagent, such as hydrochloric acid, causing strong sticking take place among the fibers and further even among the threads fabricated therefrom.

• the process may be, when so desired, carried into effect partially.
• the best mode for this purpose may be performed in the conventional printing mode. In this way, highly durable and brilliant white and color designs may be obtained, the characterizing feature of which resides in full penetration of the printed designs through the material, thus the designs appear very sharp even from the back side of the fibrous material.
• the conventional waxy and transparent touch and appearance may be substantially obviated and the desirous full-dull effect may be provided to the fibrous material under consideration.
• the swelling agent and the separating agent can be mixed into the printing paste. Pigments and/or dye stuffs may also be added thereto.
• the printing paste can be prepared so as to contain any of of the swelling agents in an amount of about 2 45 percent; a separating agent in an amount of about 0.5 percent and starch or the like paste-fonning material in an amount of about 2 25 percent, so far as virgin polyamide fibrous material is concerned. If the fibrous material has previously been treated with separating agent, the paste must preferably contain the swelling agent in an amount of about 2 45 percent and the starch and the like paste-forming material in an amount of about 2 25 percent.
• the printing paste may contain naturally various additives already referred to hereinbefore.
• the printed polyamide fibrous material is kept for the time being at room temperature, or heated at a certain elevated temperature such as 50-100 C. preferably for l 8 minutes.
• the printed areas have an excellent full-dullness, proper degree of soft touch and medium stiffness, yet not having any waxy feeling. After several repeated laundries or dry-cleaning operations, the printed design will not be subjected to any appreciable adverse effect.
• the printed designs may appear to be less colored, yet non-transparent, while the non-printed or substrate areas will represent a thicker color.
• the printed designs will be of resist-colored and appear to be non-transparent.
• the products according to the present invention represent desirous and superior full-dullness and non-waxy appearance and touch, without any appreciable loss of the strength of the fibrous material and the obtained characteristi cs are highly durable and permanent considerably irregular surface conditions. It is supposed that the superior full-dullness obtained and the disappearance of the conventional waxy appearance are attributable to the diffused reflection caused by the intentional provision of the irregular surface conditions.
• the fibrous material When the fibrous material is treated only with the swelling agent, the treated material, after being dried, will show a highly accentuated stiffness. When the material is in the form of a fabric, the latter will show a considerable paper-like touch which prevents the material definitely from being used for the clothing purpose. On the other hand, a considerable reduction in strength may generally be invited. This phenomenon is attributable to the fact that the swollen or partially dissolved fibers resulting from the above-mentioned treatment will stick together to a large extent which fact has been found from elec- $9.
• polyamide fibers are brought into contact with particles of the separating agent specifically adopted in this invention and these particles adhere to the surfaces of the fibers so that the above-mentioned mutual and adverse sticking phenomenon between fibers may be eliminated by the influence of the intermediate presence of said attached particles of the separating agent.
• the minute parti cles of the agent will effectively prevent the swollen fibers from direct contacting. It is believed that the strength of the fibrous material is maintained in the present invention by the existence of particles of anti-sticking agents between the fibers which effectively act as a kind of lubricant for allowing considerable mutual slippage when subjected to a heavy load.
• the thus treated yarn showed enough full-dullness and nonwaxy, linen like touch for clothing purposes, without loss of any appreciable strength, while a similar yarn treated with a similar liquor in the absence of said polyethylene emulsion represented too high stiffness to-be used for clothing purpose.
• the thus treated fabric showed desirous full-dullness and cotton-like feelings, without representing appreciable paperlike touch and without reducing the strength of the fabric.
