Electronic device for automatically and continuously adjusting the height of a shearing pile of textile articles having a differing thickness

A device is described which permits automatic, uniform, and precise shearing of cloth pieces, including those areas near the seams, and which thus minimizes the economic loss due to non-sheared areas of cloth. The device employs the logic processing of information continuously delivered by a detector which measures the thickness of the cloth at a point before it reaches the shearing cylinder. This information is processed in an electronic system so as to adjust properly the width of the shearing slit in synchronism with the movement of the cloth. By the technique described herein, spurious signals of thickness information caused by the presence of a seam are discarded and replaced by certain fictitious signals that will bring about the desired height of pile in the sheared cloth in the areas near the seams, while nevertheless permitting the seam to pass through the shearing slit.

Process for dyeing cellulosic textile materials

Cellulosic textile material is dyed with substantive dyes or preferably with reactive dyes. Dyeing is carried out by applying to the cellulosic material, by a non-pad method, an aqueous dye liquor which contains, in addition to the dye, a graft polymer which is obtained from an adduct of an alkylene oxide, preferably propylene oxide, with an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide. The cellulosic material is then subjected to a heat treatment, e.g. by steaming or with microwaves, or is preferably stored cold, to fix the dyes. This dyeing process affords dyeings with excellent penetration of the fabric and with level depth of shade from edge to edge.

The hydrogen bonding provided by the hydroxyl group, together with the high molecular weight and high boiling point of the polyol, mitigate against migration of the dye stuff out of the film, i.e., fading of the film, and impart long lasting color fastness to the film. Rapid diffusion of the dye bath into the film is enhanced by thermal and ultrasonic energization of the bath.

Transfer printing sheet carrying impregnant and transfer printing of cellulose, wool, silk or polyamide textile materials

The transfer sheet or web is intended for the use in a heat transfer printing process of cotton, of cotton-polyester blend or of nitrogen containing textile fibers such as wool, silk or nylon. It comprises on its surface at least one organic impregnating agent which has a melting point between 60° and 230° C. and is no polymer, at least one water insoluble, non-subliming dyestuff, and the minimum amount of a binder. The dyestuff forms a pattern or image which is heat contact printed on said textile substrate without the use of carrier vapors or vacuum. The pattern to be heat transferred may also be prepared in an electrophotographic process using a new toner comprising particles of impregnating agent, binder and dyestuff. The pattern on the transfer support is transferred at a temperature between 160° and 230° C. during 30 to 60 seconds to said textile substrate. The printings obtained have very good light, rubbing and washing fastnesses; the handling is not impaired.

Process with no heating for transfer pattern printing of a moist cellulose, wool or silk textile web, and an apparatus as well as a pattern carrier web for use in the process

In a process for transfer pattern printing of a moist textile web consisting wholly or predominantly of natural fibers, in particular cotton, and/or artificial fibers on the basis of cellulose, the pattern carrier web is a web of paper or a paper-like material which carries a pre-printed pattern of a water soluble or dispersable dye. After wetting of the textile web to a carefully controlled moisture, the textile web is joined with the pattern carrier web and the joined webs are compressed at a suitable pressure so that the pattern can be transferred without using heat. The advantage is that it will be possible to avoid both heating and use of organic solvents. It is also possible to transfer a pattern to a colored textile web since the textile web may be wetted before hand with an aqueous dye solution or dispersion instead of undyed liquid.

Block polymers of alpha-olefines, processes for producing the same, and mixtures thereof with isotactic polyolefines

Blended dyes and process for dyeing polypropylene fibers

An improved method of dyeing a polyolefin material, and preferably a polypropylene based fiber, involves a disperse dye mix including a selected plurality of disperse dyes from the same primary color group. Each dye within the mix and the concentration of each dye within the mix is selected by testing individual disperse dye solutions with an undyed sample and determining the maximum dye concentration which will produce an acceptable crocking test for that dye. A plurality of disperse dyes within the mix are each at a concentration of at least 75% of the maximum dye concentration for that individual dye. The selected dye mix is used to prepare a disperse dye mix solution which is then contacted with the polyolefin material to reliably dye the material without fastness problems. A red dye mix, a blue dye mix, and the yellow dye mix may each be prepared and may each be separately used to dye polypropylene fibers with relatively dark shade without crocking problems. Different proportions of each of the three dye mixes may be used to dye polypropylene fibers at various selected shades and color depths.
