preparation example 1～5

[0041] As shown in Table 1, the main difference of Preparation Examples 1-3 lies in the mass ratio of the mixed solution to the prepolymer; the main difference of Preparation Examples 1, 4, and 5 lies in the different stirring speeds.

[0042] Taking Preparation Example 1 as an example below,

[0043] The preparation method of microcapsules:

[0044] Preparation of oil phase solvent: Weigh 20g of simethicone in container A, stir evenly, and set aside;

[0045] Preparation of aqueous phase emulsion: weigh 9g of epoxy resin in container B, add epoxy resin curing agent 593, the mass ratio of epoxy resin to epoxy resin curing agent 593 is 4:1, stir and mix evenly, and pre-cure for 5 minutes , to obtain a prepolymer; add 20ml carbon tetrachloride and 3ml sorbitan oleate to the prepolymer, stir well; then add the mixed solution of ethylenediamine and alkali-resistant penetrating agent TF-107B, The mass ratio of the liquid to the prepolymer is 1:5, and it is stirred evenly at a spe...

Embodiment 1～4

[0051] As shown in Table 2, the main difference of Examples 1-4 is that the proportioning of raw materials is different.

[0052] The following is described by taking Example 1 as an example, wherein the microcapsules prepared in Preparation Example 1 are used. Silicone softener was purchased from Dongguan Jiahong Silicone Technology Co., Ltd. The amine swelling agent is ethylenediamine, and the alkali-resistant penetrating agent is alkali-resistant penetrating agent TF-107B. The primary product of printed crepe is to first use all cotton yarns to form strands, and then weave the strands into gray fabrics. The twist of the entire cotton yarns is 180 twists / m.

[0053] The production method of the high tear strength printed crepe that embodiment 1 provides specifically comprises the following steps:

[0054] Padding: padding the primary printed crepe cloth in the anti-wrinkle finishing solution, two dipping and two rolling, the liquid retention rate is controlled above 90%, a...

Embodiment 5

[0060] Embodiment 5, the difference between this embodiment and embodiment 3 is:

[0061] The mass ratio of amine swelling agent to alkali-resistant penetrating agent is 2.5:1.

Abstract

The invention provides a production method of a high-tear-strength printed crepe and the printed crepe. The production method comprises the steps of padding, stretching, pre-drying and baking. In the pre-drying treatment process, alkaline resin finishing liquid is slightly crosslinked with an amorphous region of cotton fiber, meanwhile epoxy resin in a microcapsule material is crosslinked with the amorphous region of the cotton fiber, the structure of the capsule material is changed to enable a microcapsule to be broken, an amine swelling agent and an alkali-resistant penetrant seep out, the alkali-resistant penetrant reduces the surface tension of the surface of the cotton fiber, the amine swelling agent is accelerated to permeate into a setting area of the cotton fiber, the internal structure of the setting area is changed, the tearing strength of the cotton fiber is improved, and the problem that the tearing strength of a printed crepe primary product is severely reduced after resin finishing is obviously improved; and in addition, during baking, the alkaline resin finishing liquid is quickly crosslinked with the amorphous region of the cotton fiber to form reticular macromolecules, so that the cotton fiber cannot be relatively moved and the shrink resistance of the printed crepe is improved.

Description

technical field [0001] The application relates to the technical field of crepe cloth, more specifically, it relates to a production method of high tear strength printed crepe cloth and the printed crepe cloth. Background technique [0002] Crepe is a thin plain cotton fabric with uniform longitudinal wrinkles on the cloth surface, and it can also be called crepe. Crepe has a cool hand feel, good weft elasticity, and is light and soft. It is suitable for making all kinds of shirts, skirts, pajamas, and bathrobes. [0003] The warp yarns used in crepe cloth are mostly ordinary cotton yarns, and the weft yarns are shaped strong twisted yarns. After being woven into gray fabrics, they are firstly processed by pre-treatments such as singeing, loose desizing, scouring, bleaching and drying, so that the fabric can withstand a certain period of time. Treated with hot water or hot lye, the weft shrinkage is about 30%, and the crepe cloth with uniform folds is obtained; then the crep...
