CN101942756A - Method for improving skewness of low-density knitted fabric - Google Patents

Abstract

The invention provides a method for improving skewness of a low-density knitted fabric, which is characterized by being realized through a deviation correcting device of a slitting setting machine and comprising the following steps of marking a slitting mark line, slitting, shaping and the like. By adopting the method, the skewness of the washed low-density knitted fabric can meet the textile industry standard without changing features of the fabric such as appearance, density and the like, thus being especially suitable for the textile industry.

Description

A kind of method of improving low-density knitted fabric skew

Technical field:

The present invention relates to a kind of method of improving the knitted fabric skew, particularly a kind of method of improving low-density knitted fabric skew.

Technical background:

The latitude plain stitch, it is a kind of tissue the most the most frequently used in the single jersey, in process of production, often run into directly to lines (wale) crooked and form thus copy the waist product, the problem that crook in waist seam seam road, for the client can not accept, exported product generally requires directly to must not crook greater than 5%, textile industry standard FZ/T 73008-2002 " knitted t-shirt " regulation is not more than 6%, and low-density knitted fabric washing back skew reaches more than 15% especially, general solution is to utilize s, the z twist yarn is offset the internal stress of yarn, or the underfill coefficient of minimizing fabric etc., but these methods all are in the outward appearance that changes fabric, indexs such as characteristic are got off and are realized.

Summary of the invention:

Purpose of the present invention is exactly to provide a kind of under the situation of characteristics such as the outward appearance that does not change fabric, rare close degree, makes low-density knitted fabric washing back skew reach the method for textile industry standard.

The object of the present invention is achieved like this: a kind of method of improving low-density knitted fabric skew, and it is characterized in that utilizing the well straightening device that cuts open width of cloth setting machine to realize, adopt following steps:

1), do and cut open width of cloth mark line: before weaving cotton cloth, earlier fixing on loom some arbitrary interval is extracted 2～3 pins and does and cut open width of cloth mark line, after weave cotton cloth;

2), cut open the width of cloth: after knitted fabric weaves, cut open from cuing open width of cloth mark line when cuing open the width of cloth, guarantee that the vertical line of knitted fabric is straight;

3), typing: utilize the well straightening device that cuts open width of cloth setting machine to increase fabric stroke on one side, make the horizontal skew of weft of typing back fabric be controlled at 18～23%, low-density knitted fabric washing back skew is reached in 6%.

The present invention compared with prior art has the following advantages:

Because utilizing the well straightening device that cuts open width of cloth setting machine that fabric stroke distances is on one side done arbitrarily adjusts, thereby under the situation of characteristics such as the outward appearance that does not change fabric, rare close degree, the skew of any low-density knitted fabric can be controlled in the scope of standard 6%.

The specific embodiment:

Before weaving cotton cloth, earlier fixing on loom some arbitrary interval is extracted 2～3 pins and does and cut open width of cloth mark line, after weave cotton cloth; After knitted fabric weaves, cut open from cuing open width of cloth mark line when cuing open the width of cloth, guarantee that the vertical line of knitted fabric is straight; The well straightening device that width of cloth setting machine is cutd open in utilization increases fabric stroke on one side, makes the horizontal skew of weft of typing back fabric be controlled at 18～23%, and low-density knitted fabric washing back skew is reached in 6%.

Embodiment:

With 32 single thread single jerseys, grammes per square metre is 120g/m ², fabric width is that the low-density single jersey of 130cm is an example, sets its horizontal skew of weft and is controlled at 18～23% o'clock, skew can be controlled in 6%.

A, before weaving cotton cloth, fix some arbitrary intervals earlier and extract 2～3 pins and do and cut open width of cloth mark line, after weave cotton cloth;

After B, knitted fabric weave, cut open from cuing open width of cloth mark line when cuing open the width of cloth, guarantee that the vertical line of knitted fabric is straight;

When C, typing, the well straightening device that width of cloth setting machine is cutd open in utilization increases fabric stroke on one side, make the more parallel many 26cm of stroke (setting horizontal skew of weft 20%) in stroke ratio the right on the fabric left side, the horizontal skew of weft after the single jersey typing was controlled at 18～23% o'clock thus, and skew can be controlled in 6%.

1. method of improving low-density knitted fabric skew is characterized in that utilizing the well straightening device that cuts open width of cloth setting machine to realize, adopts following steps:

1), do and cut open width of cloth mark line: before weaving cotton cloth, earlier fixing on loom some arbitrary interval is extracted 2～3 pins and does and cut open width of cloth mark line, after weave cotton cloth;

2), cut open the width of cloth: after knitted fabric weaves, cut open from cuing open width of cloth mark line when cuing open the width of cloth, guarantee that the vertical line of knitted fabric is straight;

3), typing: utilize the well straightening device that cuts open width of cloth setting machine to increase fabric stroke on one side, make the horizontal skew of weft of typing back fabric be controlled at 18～23%, low-density knitted fabric washing back skew is reached in 6%.
