Method for making a ladderproof knitted elastomeric polyamide fabric

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a method for making a ladderproof knitted elastomeric poly- amide fabric, and also relates to the thus made fabric.

[0002] As is known, for making ladderproof elasti­cized fabrics, which are for example used for making bath costumes and the like, there are conventional­ly used knitted fabrics consisting of a polyamide yarn and an elastomeric yarn.

[0003] The elastomeric yarn is threaded on the bottom comb or bar of the loom, whilst the poly­amide yarn is threaded on the top bar or comb of the loom.

[0004] Upon knitting, the made fabric is subjected to a raising step, which is carried out on the back or reverse of the fabric.

[0005] Knitted fabrics made by this method, even if they are broadly used, have been found to be susceptible to improvements, mainly with respect to their outer aspects and their touch or hand cha­racteristics.

SUMMARY OF THE INVENTION

[0006] Accordingly, the aim of the present inven­tion is to solve the above mentioned problem, by providing a method for making such a knitted ela­stomeric-polyamidic fabric which has a "hide" aspect, and which is particularly pleasant to touch while having satisfactory resiliency proper­ties.

[0007] Within the scope of the above mentioned aim, a main object of the present invention is to provide such a method which can be carried out without the need of performing substantial modifica­tions in the textile machines, which are convention­ally used for making elasticized or resilient fa­brics.

[0008] Another object of the present invention is to provide such a method which can be quickly and easily carried out and can provide a knitted fabric with novel characteristics and which moreover has a very reduced cost.

[0009] According to one aspect of the present in­vention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a method for making an elastomeric polyamide knitted fabric, characterized in that said method comprises the steps of: threading the polyamide yarn on the bottom comb of a loom or textile machine, threading the elastomeric yarn on the top comb of said loom, and knitting said fabric.

[0010] Further characteristics and advantages of the invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0011] According to the invention, the method for making an elasticized ladderproof knitted fabric has the main feature that said method comprises the steps of threading the elastomeric yarn on the top comb of a ladderproof chain loom and threading the polyamide yarn on the bottom comb of said loom, which is just the reverse of the conventionally used methods.

[0012] Upon the yarn engaging steps, the loom or textile machine is operated in a conventional way so as to provide a knitted fabric: then on the thus made knitted fabric there is carried out a further raising step which, according to the invention, and contrarily to known procedures, is carried out on the right side of the knitted fabric.

[0013] Thus, a knitted fabric is obtained which has a "hide" type of aspect, which is particularly pleasant to touch and has a very broad range of applications.

[0014] By way of a merely indicative example, it is indicated that very satisfactory results have been obtained by using a ladderproof chain loom with a loom fineness from 32 E to 28 E and with a binding or weave value at the bottom comb of 10/34 and a binding value at the top comb of 10/12, with a raw loop stitch number of substantially 28/cm.

[0015] The used polyamide yarn was of the (40/36 filament denier) type, and the elastomeric yearn was of the 40/1 denier type.

[0016] The obtained finished knitted fabric con­sists of 18 % elastomeric material, 82% polyamide material and is made with a height of about 150 cen­timeters, a weight of 245 grams/m² and 370 grams for linear meter (± 10%).

[0017] The number of loop stitches for centimeter, through the piece length, is of about 35/40, where­as the number of wefts or quills, in the height di­rection, is of 26.5.

[0018] From the above disclosure it should be appa­rent that the present invention fully achieves the intended aim and objects.

[0019] In particular the fact is to be pointed out that a knitted fabric making method has been provided which, by reversing conventional making procedures, provides a knitted elasticized fabric having great­ly improved characteristics, both with respect to the aesthetic aspect and with respect to the touch sensivity.

[0020] While the invention has been disclosed and illustrated with reference to a preferred embodiment thereof, it should be apparent that the disclosed embodiment is susceptible to many modifications and variations all of which will come within the scope and spirit of the appended Claims.
