Embodiment 1

[0030] Raw materials:

[0031] Island-fixed sea-island staple fiber was purchased from Yangzhou Tianlun Fiber Co., Ltd.

[0032] Polyester filament: the total fineness is 68D-75D, purchased from Zhejiang Xingfa Chemical Fiber Group Co., Ltd.;

[0033] PVA is a widely used water-soluble high molecular polymer, its performance is between plastic and rubber. purchased from Suzhou COSCO Chemicals.

[0034] PU resin is a common raw material for the manufacture of microfiber leather.

[0035] The DMF aqueous solution is a dimethylformamide (DMF) solvent, which is a common raw material for the DMF impregnation process in textiles.

[0036] Disperse dyes can be purchased from Zhejiang Longsheng Group, or you can configure disperse dyes yourself:

[0037] For every L of disperse dye, the dosage of high-temperature leveling agent is 1.0g, the dosage of diffusing agent is 0.5g, and the dosage of acetic acid with a concentration of 98% by weight is 1g. The high-temperature leveling a...

Embodiment 2

[0058] The difference with embodiment 1 is:

[0059] In step (4), every 100 kilograms of PVA aqueous solution is mixed with 15 kilograms of polyvinyl alcohol PVA and 85 kilograms of water in the PVA aqueous solution.

[0060] Every 100 kilograms of PU resin and DMF mixture is composed of 20 kilograms of polyester polyol PU resin and 80 kilograms of dimethylformamide DMF.

[0061] Every 100 kg of DMF aqueous solution is composed of 20 kg of dimethylformamide DMF and 80 kg of water.

[0062] Every 100 kg of cleaning agent for pre-dyeing treatment is composed of 3 kg of TF-108 scouring agent, 3 kg of JFC penetrating agent, 12 kg of liquid alkali (30% NaOH aqueous solution), 3 kg of TF-101C deoiling spirit and 79 kg of water. All the other are with embodiment 1.

Abstract

The invention relates to high-strength terylene microfiber needling fabric and belongs to the technical field of needling non-woven cloth. The high-strength terylene microfiber needling fabric is prepared by the following steps: performing non-woven double carding and double lapping on island type island short fiber to obtain double-layer cotton web; clamping base cloth which is obtained by using polyester filament yarn through a hydraulic loom in the middle of the double-layer cotton web; performing non-woven needling to obtain composite base cloth; starching; performing polyurethane (PU) resin impregnation; performing alkali reducing splitting; dyeing; drying; and performing double-sided sanding, wherein the polyester filament yarn is 68 to 75 D, the fineness of the island type island short fiber is 1 to 3 D, the island type island short fiber contains 37 islands and has the length of 38 to 51 mm, and the sea / island ratio is 30 / 70. The high-strength terylene microfiber needling fabric is low in dye cost and water consumption, uniform in dyeing, bright in color and luster, and high in color fastness and air permeability, enhances the stretching resistance, and takes both leather feeling and fluff feeling into consideration.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a high-strength polyester superfiber needle-punched composite fabric. Background technique [0002] In the prior art, microfiber non-woven fabrics are usually used as non-woven base fabrics and synthetic leathers. The island-in-the-sea polyester staple fiber production technology is a relatively new and advanced technology for producing superfine fibers in the world. There are manufacturers in our country that can carry out large-scale production of sea-island polyester staple fibers with independent intellectual property rights. It is made through the advanced compound production technology of one component of conventional staple fiber polyester and one group of cationic modified polyester. Viewed from its cross-section, the sea-island short fiber of fixed island type is that one component is surrounded by another component in a fine and dispersed state, as ...
