Definitions

• This invention relates to patterned fabrics particularly knitted fabrics provided with relief patterns and to a method of making the same. More particularly this invention relates to patterned fabrics having at least two color relief patterns.
• Relief patterned and differently colored fabrics are known in the textile industry and have heretofore been produced by knitting and in particular by weft knitting or warp knitting, their relief patterns being obtained for example, in the process of stitch formation by making the lengths of the sinker loops on relief pattern forming threads different from those of sinker loops of threads constituting the fabric base or ground. 1.
• the relief effect of the pattern has been produced by the combination of rib courses and plain courses interlocked according to a given design.
• the difference between the height of the relief effect and the ground depends on the difference in the length of the aforesaid sinker loops forming the rib and plain stitches respectively.
• a further disadvantage of this method of producing relief patterned fabric consists in the tedious, time consuming prepara tion of the conventional and/ or synthetic yarns involved.
• the synthetic yarns are usually textured and have to be predyed in order to produce color patterns therefrom as it is not possible to produce fabrics from the undyed yarns and to then subject them to piece-dyeing for obtaining multi-color effects.
• the output of the machines involved is relatively low since in producing relief patterns according to the known methods one rib course and two plain courses usually alternate so that the output of the machine having 36 feeders amounts to 12 courses per revolution.
• the coloration of the relief patterned knitted fabric prepared by the known processes is accomplished by the coloration of the respective binding yarns it having been found desirable that the shrinkability of the relief pattern forming yarns and that of the yarns forming the fabric ground be the same or at least approximately similar.
• Still another object of the invention is to provide a method of producing knitted fabrics having a relief pattern permitting higher productivity to be obtained.
• Yet another object of the invention is to provide such a method where new and improved results in the production of patterned fabrics and especially of knitted fabrics can be realized.
• a relief patterned fabric consisting of at least two yarn types each having a different shrinkability as well as a different dye afiinity, the less shrinkable yarns forming the relief pattern and those of higher shrinkability forming the ground of the fabric.
• the difference in shrinkability between the two types of yarns amounts most advantageously in accordance with the invention to at least 15%.
• yarns containing filaments or staple fibers prepared from co-polyeach having adifferent shrinkability as well as a different dye affinity subjecting the resultant fabric simultaneously or in sequence to a thermal treatment and a dyeing procedure in a dyeing bath having a substantially different affinity for one of the types of yarn forming the fabric,
• the shrink-age of the fabric can be preferably carried out in a dyeing bath having amarked afiinity for the less shrinkable yarns which form the relief pattern.
• a knitted fabric having a relief pattern in accordance with the invention is made for example on a Jacquard weft knitting machine, the more shrinkable yarns being used for knitting the rib courses while the less shrinkable yarns are used for knitting the plain courses forming the relief pattern, the difference in shrinkablity between the two different types of yarn amounting to at least 15%.
• the knitted fabric is made of an undyed material, the ground yarns, i.e., the more shrinkable yarns consisting of filament or synthetic spun yarns containing as shrinkable component copolyester fibers prepared from polyethylene terephthalate and polyethylene isophthalate or of shrinkable fibers base on polyacrylonitrile, polyvinyl chloride, polypropylene and the like.
• the shrinkage and the imparting of an at least two color dyeing to the knitted fabric is carried out in the wet state by heating the fabric in a dyeing bath having an affinity for only one of the types of yarn forming the fabric.
• a shrinkage of the more shrinkable yarn forming the ground of knitted fabric and thus an increased relief effect of the pattern formed from the less shrinkable yarns
• a coloration of the yarn type which is dyeable in the said dye bath within the range of its active temperature.
• the latter type of yarn can be constituted by the pattern forming yarn, i.e., the less shrinkable yarn.
• the use of the more shrinkable yarn for this purpose is not excluded.
• the relief pattern becomes not only more obvious as hereinabove set forth but differs moreover in color from the shrunk threads forming the fabric ground.
• the method of the invention is utilized in connection with the above described knitting machines having 36 feeders, it is possible by using materials with different shrinkabilities to obtain a relief pattern with an alternating one rib course and one plain course in the fabric, the output of the machines thereby being increased to 18 courses per revolution, i.e., by more than /2 as compared with the usual method of knitting one rib course and two patterned plain courses.
• the method of the invention for producing at least two color relief patterned fabrics from the point of view of both quality and output are more advantageous than any of the heretofore known combinations of materials or techniques.
• the considerably simplified method according to the invention makes it possible in a single operation to obtain an excellent relief effect which is apparent after shrinking on the face of the fabric together with the simultaneous or eventual different coloration of the corresponding binding threads forming the pattern. 7
• EXAMPLE 1 There was used in this case for the production of a knitted fabric having a colored relief pattern a Jacquard knitting machine ODZI provided with pattern wheels, 36, 7", gg. .18" and 36 feeders.
• the material for the rib courses was a yarn Nm 48 consisting of 40% of Velana, i.e., copolyester fiber based on polyethylene terephthalate and polyethylene isophthalate and 60% of Tesil 31, i.e., a copolyester fiber and the material for the plain courses was a polyamide textured yarn Td 120.
• FINISHING Shrinkage Steaming for 30-60 seconds or 10 minutes shrinking at boil. The shrinking can also be carried out in the dyeing bath during the dyeing process. 7
• Scouring For 30 minutes in a bath containing'0.2 g./l.
• the starting temperature of 40 C. was slowly increased to the boiling point of the bath and after 11.5 hours slowly reduced.
• the fabric was thereafter rinsed in warm and cold water.
• Hydroextracting Slight Drying: To C., or heat setting at C. for 30 to 60 seconds.
• EXAMPLE 2 There was used for the production of a knitted fabric having a color relief pattern a knitting machine METO, 32", gg. 20" and 44 feeders.
• the material for forming the rib courses was a Nm 48 yarn containing 40% of Velana S manufactured by Silon National. Enterprise, Plana, Czechoslovakia, i.e., copolyester fiber formed from polyethylene terephthalate and polyethylene isophthalate, and 60% of Velana N manufactured by Silon National Enterprise, Plana, Czechoslovakia, i.e., a non-shrinkable copolyester fiber, and for the plain course there was used a polyamide textured yarn, Td 120.
• EXAMPLE 3 There was used for the production of a knitted fabric having a colored relief pattern a Jacquard knitting machine ODZI provided with pattern wheels e536, 7", gg. 18" and 36 feeders.
• EXAMPLE 4 For the production of a knitted fabric having a colored relief pattern there was used a raschel machine, gg 24 sax.
• the knitted fabric was made by using two or more yarn systems, some of which contained Nm 48 x 2 yarn consisting of 40% Velana S (a copolyester fiber based on polyethylene terephthalate and polyethylene isophthalate) and 60% of Tesil 31, and the other containing a textured yarn Td 120 formed from polyamide, polyester, or polypropylene.
• Nm 48 x 2 yarn consisting of 40% Velana S (a copolyester fiber based on polyethylene terephthalate and polyethylene isophthalate) and 60% of Tesil 31, and the other containing a textured yarn Td 120 formed from polyamide, polyester, or polypropylene.
• EXAMPLE 5 There was used for producing a knitted fabric having a colored relief pattern a Jacquard knitting machine ODZI provided with pattern wheels, gg. 18". As material for the rib courses a yarn Nm 60 was used, containing 40% Velana S, i.e., copolyester fiber based on polyethylene terephthalate and polyethylene isophthalate, and 60% of Velana N, i.e., non-shrinkable polyester fiber, and for the plain courses a textured polyester yarn, Td 150. Finishing:
• a shrunk and dyed knitted fabric the said fabric being composed of interlooped rib courses and plain courses of yarns arranged in a relief pattern, the yarns of each course having dilferent heat-shrinkability characteristics, different affinity for particular dyes, and being shrunk to different lengths, so that the less-shrinkable yarns form a relief pattern having a first color and the more-shrinkable yarns form a base for the relief pattern and have a different second color.
