Problems solved by technology

[0018] However, this particular fabric is insufficient in terms of thinness (softness) and strength
[0019] Thus, there has not been established a method for producing a scrim that is excellent in all of softness (bending resistance / tensile elongation), tensile strength, mesh shifting property, etc.

Embodiment 1

[0152] Ne10 / 2s (double yarn of cotton count (number) 10) polyester machine-spun yarn is plain-woven at intervals of 8 warp yarns / inch and weft yarn 8 yarns / inch, and EVA-acrylic Resin (manufactured by Showa Denko, product name PSA SE-8001) is used to make a cheesecloth by mending the intersection points of the warp and weft yarns.

[0153] The produced cheesecloth was subjected to calender processing using a calender (manufactured by Yuri Roll Co., Ltd., Type: H.P.C.M) to perform a thinning process.

[0154] A pair (two pieces) of calender rolls was used, and one calender roll was made of iron with a roll diameter of 350 mm, and the other calender roll was made of resin with a roll diameter of 500 mm.

[0155] The iron calender rolls being processed were heated to 150° C., the linear pressure applied to the cheesecloth was set to 780 kgf / cm, and the moving speed of the cheesecloth was set to 10 m / min.

Embodiment 2

[0158] In addition to changing Ne10 / 2s (double yarn of cotton yarn count (number) 10) polyester machine-spun yarn to Ne14 / 1s (single yarn of cotton yarn count (number) 14) polyester In addition to machine spinning, changing the distance between warp and weft to 14 threads / inch for warp and 14 threads / inch for weft, and using vinyl acetate-based copolymers for mending, the same In the same manner as in Example 1, a cheesecloth was manufactured and calendered.

Embodiment 3

[0160] In addition to changing Ne10 / 2s (double yarn of cotton count (number) 10) polyester machine-spun yarn to Ne30 / 1s (single yarn of cotton yarn count (number) 30) polyester Except for machine spinning and changing the distance between warp and weft to 22 warps / inch and 21 wefts / inch, a scrim was produced and calendered in the same manner as in Example 1.

Abstract

The invention provides a method for thinning the fabric without greatly reducing the strength of the fabric in a plain weave or leno weave fabric with a high porosity such as denim cloth. The invention is a plain weave or leno fabric. A method of manufacturing a leno-woven thinned fabric, which is a plain weave or A method for producing a leno-woven thinned fabric, wherein the thinning process is performed by passing the fabric between rotating calender rolls to perform calendering processing with pressure and heat, and during the calendering process, the The surface temperature of at least one of the calender rolls in contact with the fabric is a temperature above the glass transition point of the fibers constituting the fabric, and the average thickness (T1) of the fabric before thinning treatment is different from the average thickness of the fabric after thinning treatment. (T2) satisfies the relationship of the following formula (1). 0.25≤(T1–T2) / T1(1).

Description

technical field [0001] The present invention relates to the manufacturing method of plain weave or leno weave (leno weave) thinning treated fabric, more specifically, it is to make the thickness greatly reduce by carrying out calendering processing under specific conditions, and has excellent A method of manufacturing a coarse-mesh fabric such as cheesecloth with excellent physical properties. Background technique [0002] Coarse cloth is a fabric with a high porosity (coarse mesh), and it is used as an agricultural material for the purpose of heat preservation, shading, frost protection, insect protection, wind protection, etc.; it is used to strengthen the cover and back of the book when making books Book-making materials; living materials such as flower packaging materials; industrial materials such as mounting reinforcement for floor materials, reinforcement cloth for building waterproofing, substrates for painting, etc.; food for wrapping meat and filtering soup Variou...
